The etiology and p...Androgenic alopecia, also known as seborrheic alopecia, is the most common hair loss disorder in dermatology clinics, mainly characterized by hair follicle miniaturization and progressive hair loss. The etiology and pathogenesis of androgenic alopecia are not clear, but may be related to heredity and androgen metabolism. Currently, minoxidil and finasteride are the only two drugs approved by the U.S. Food and Drug Administration (FDA) for AGA treatment, other treatments include oral minoxidil, hair transplantation, low energy laser therapy (LLLT), platelet-rich plasma (PRP), Chinese medicine microneedles, and combination therapy. With the development of medicine and science, we have ushered in the era of biologics and targeted therapy. In recent years, a variety of signaling pathways for androgenic alopecia have been found, which may provide a basis for targeted therapy for androgenic alopecia.展开更多

Oral, topical, and injectable autologous treatments demonstrate ability to stimulate hair re-growth, but the response is suboptimal or plateaus off. Synthetic combination of the peptide complex and hyaluronic acid (P-HA) demonstrated hair regrowth in alopecia patients. Electronically-operated pneumatic injections (EPI) generate micro-trauma in the dermis and under wound-healing conditions may enhance regeneration effect of P-HA. Methods: Subjects seeking improvement of their male pattern hair loss (Hamilton-Norwood type 2-4) received the P-HA treatments through EPI. The course included 4 treatments every two weeks over the 8-week period. In 6 months, the hair growth was assessed comparative to baseline by global clinical photography and digital phototrichograms. The treatment safety and tolerability were documented through the whole study period. Results: Twelve men (30-45 years old) completed the treatment course with high tolerability and without adverse events. Post-treatment assessment of the previously bald areas showed improved coverage on the clinical photographs. The phototrichograms demonstrated statistically significant increase in terminal hair density by 36%, cumulative hair thickness by 37%, and follicular units by 20%;all contributing to a 38% increase in cumulated hair density (all p Conclusion: Electronic pneumatic injections are well tolerated and can be safely used for the needle-free administration of the peptide-hyaluronic acid combination in MAGA therapy. We achieved significant hair re-densification in the balding scalp. The exact role of the EPI-induced impact in the hair re-growth mechanism remains to be ascertained. .展开更多

Methods Eighty-four patients with androgenic alopecia were divided into catgut embedment group （group A） and western medicine group （group B） on the basis of random number table and according to the order of treatment. For the pateints in group A, Shenguan （肾关） on both sides, Minghuang （明黄） and Zusanli （足三里 ST 36） were selected to receive catgut embedment therapy, once every month, combined with moxibustion on the lower abdomen and local bloodletting treatment. For the patients in group B, finasteride 1mg/d was orally administrated. The treatment period for two groups was 3 months, and the follow-up visit lasted for 3 months. Serum testosterone （T） and estradiol （E2） contents were detected respectively before treatment, after i month and 3 months of treatment and after 3 months of follow-up visit, and the specific values were calculated to make statistical analysis of T, E2, T/E2 and curative effects of the two groups after i month and 3 months of treatment and after 3 months of follow-up visit. Results There was no statistical significance in curative effect between the two groups after i month of treatment （P〉0.05）, and the curative effect in group A were better than that in group B after 3 months of treatment or after 3 months of follow-up visit （both P〈0.05）; E2 level in group A was lower than that in group A after 3 months of treatment （P〈0.05）; T, E2 and T/E2 in group A were all lower than that in group B after 3 month of follow-up visit （all P〈0.05）. Conclusion The curative effect of treating androgenic alopecia with catgut embedment, moxibustion and bloodletting is definite, and its mechanism of action may be related to the reduction of T levels and T/E2 values.展开更多

SA is of 2 types, symptomatic and essential, and 3 clinical types, moth-eaten or patchy pattern, diffuse pattern and a combination of both. SA in our case indicated symptomatic SA with moth-eaten hairloss. A 46-year-old Japanese homosexual man experienced hairloss followed by the pruritic skin rash. Physical examination of the scalp showed diffusely spread papulosquamous erythema and incomplete hairloss around the lesions. The scalp lesions appeared as “moth-eaten alopecia”. Serological examination for syphilis and HIV were positive. Thus, SA complicated with HIV infection was diagnosed. He was treated with a single perioral dose of ampicillin for 4 weeks, then his condition improved rapidly and hair regrowth occurred. HIV-infected persons show a high incidence of syphilis. Therefore, HIV test should be considered for patients with alopecia.展开更多

Alopecia areata is frequently associated with immune-medi- ated diseases with skin manifestations such as psoriasis and lichen planus, or without skin manifestations such as autoimmune thyroiditis and idiopathic thrombocytopenic purpura. Helicobacter py/ori （H. pylorl） infection is present in around 50% of the world＇s population and has been associated with a variety of immune-mediated extra-digestive disorders including autoimmune thyroid- itis, idiopathic thrombocytopenic purpura, and psoriasis. A case of a 43-year old man with an 8-too history of alopecia areata of the scalp and beard is presented. The patient was being treated by a dermatologist and had psychiatric support, without any improvement. He had a history of dyspepsia and the urea breath test confirmed H. pylori infection. The patient went into remission from alopecia areata after H. pylori eradication. If such an association is confirmed by epidemiological studies designed for this purpose, new therapeutic options could be available for these patients, especially in areas where infection with H, pylori is highly prevalent.展开更多

The gross appearance, growth characteristics, pathological changes in skin, and major organs of B6.KM-AA mice were observed. Counts and proportions of CD4＋ and CD8＋ T lymphocytes in peripheral blood were determined by flow cytometry. Results show that congenic B6.KM-AA mice were obtained after 10 generations of backcrossing/intercrossing. B6.KM-AA mice grew slower than B6 control mice and AA skin lesions were developed by four weeks of age. The number of hair follicles was reduced, but hair structures were normal. Loss of hair during disease progression was associated with CD4＋ and CD8＋ T lymphocytes infiltration peri- and intrahair follicles. No pathological changes were found in other organs except for the skin. In the peripheral blood of B6.KM-AA mice, the percentage of CD4＋ T cells was lower and percentage of CD8＋ T cells higher than in control mice. These findings indicate that B6.KM-AA mice are characterized by a dysfunctional immune system, retarded development and T-cell infiltration mediated hair loss, making them a promising new animal model for human alopecia areata.展开更多

According to the antique treaties, the foundations of traditional Chinese medicine are based in maintaining the harmony between Qi (energy), Jing (essence) and Shen (spirit). Alterations in this harmony can develop and determine the appearance of disease. Therapeutic effects of Qigong are helpful in the prevention and treatment of several diseases. It's main role in restoring body functions is due to the communication between internal organs, tissues and cells. The main goal of this work is to show the efficacy of Qigong in the treatment of a dermatological disease characterized by the appearance of circular or oval patches of missing hair, known as alopecia universalis. For western medicine the exact cause of this illness is not totally revealed, however, it's attributed to psycological, genetics and metabolic alterations. From the traditional Chinese medicine perspective, hair alterations are framed in the area of the water energy, represented by the kidney organ. The results of Qigong treatment suggested that the cranial hair follicles had been activated since the first treatment. As treatment progressed, the cranial hair follicles continued to grow, what's more, the brightness and pigmentation of the hair also increased. Therefore, in the clinical conditions evaluated, Qigong could be an effective alternative treatment in consideration of the visible evidence about rapid and long lasting results.

文摘Objective This study aimed to comprehensively investigate the potential protective effects and underlying mechanisms of taurine against dihydrotestosterone(DHT)-induced androgenetic alopecia(AGA)in male C57BL/6 mice,with a focus on hair follicle cycle modulation,cellular proliferation/apoptosis,and key related signaling pathways.Methods Six-week-old female C57BL/6 mice were initially used to assess the hair growth-promoting potential of taurine.After acclimatization,they were randomly assigned to three groups(n=8):control(regular drinking water),taurine(drinking water containing 1%taurine),and minoxidil(topical 2%minoxidil,positive control).For the AGA study,male C57BL/6 mice were randomly divided into five groups(n=8):control(physiological saline),DHT(model group,1 mg/d DHT),DHT+low-dose taurine(1 mg/d DHT+2 mg/d taurine),DHT+high-dose taurine(1 mg/d DHT+10 mg/d taurine),and DHT+minoxidil(positive control,1 mg/d DHT+topical 2%minoxidil).One day before treatment initiation,dorsal hair was shaved with scissors,and residual hair was removed using a depilatory cream.DHT and taurine were administered via daily intraperitoneal injection.Hair regrowth was assessed by photographing the depilated area at regular intervals and quantified using a four-point grading system(0-3).Dorsal skin samples were collected on day 14 for histological analysis(H&E staining),immunofluorescence staining(Ki67 for proliferation,TUNEL for apoptosis),ELISA(DHT quantification),RT-qPCR,and Western blot analysis to evaluate the expression of key genes and proteins(androgen receptor(AR),transforming growth factor(TGF)‑β1,TGF‑β2,Dickkopf-1(DKK1)).Results In female mice,taurine supplementation significantly accelerated hair growth,with effects comparable to minoxidil.This was evidenced by an earlier transition from pink(telogen)to black(anagen)skin and increased hair growth scores.Histological analysis showed that taurine increased hair follicle count and dermal thickness.Immunofluorescence confirmed enhanced keratinocyte proliferation in the hair matrix.In the DHTinduced AGA model,DHT significantly extended the telogen phase,inhibited hair growth,increased skin DHT content,and induced hair follicle miniaturization.Taurine treatment,particularly at the high dose,effectively counteracted these effects:it promoted the telogen-to-anagen transition and improved hair growth scores.Histomorphometric analysis showed that taurine significantly restored DHT-induced reductions in dermal thickness,hair follicle count,hair bulb depth,and follicle size.Taurine treatment also reduced apoptosis and promoted the proliferation of hair follicle cells,as demonstrated by Ki67 and TUNEL assays.Crucially,RT-qPCR and Western blot analyses revealed that DHT significantly up-regulated the expression of AR,TGF‑β1,TGF‑β2,and DKK1 at both mRNA and protein levels in dorsal skin.Taurine administration markedly down-regulated the expression of these pathogenic factors,bringing them closer to the levels observed in the control group.Conclusion Taurine demonstrates significant efficacy in alleviating DHT-induced AGA in male C57BL/6 mice.Its protective effects are mediated through multi-faceted mechanisms.(1)Promoting hair follicle cycle progression:it accelerates the transition from telogen to anagen,counteracting DHT-induced prolongation of the telogen phase.(2)Modulating cellular dynamics:it stimulates the proliferation of hair matrix keratinocytes and reduces DHT-induced apoptosis within hair follicle cells.(3)Suppressing androgen-driven pathogenic pathways:it downregulates the expression of critical molecules in the AGA pathway,including AR,the cytokines TGF-β1 and TGF-β2,and the Wnt pathway inhibitor DKK1.Given its favorable safety profile and multi-targeted action,taurine emerges as a promising novel therapeutic candidate or adjunct for treating AGA.Further investigation into its clinical potential and precise molecular mechanisms is warranted.This study provides a robust preclinical foundation for considering taurine supplementation or topical application in hair loss management strategies.

文摘The androgenetic alopecia(AGA)is the most prevalent clinical manifestation of hair loss,believed to be associated with excessive dihydrotestosterone(DHT)caused by typeⅡ5α-reductase(5αR2).The utilization of oral finasteride(FNS),which selectively inhibits 5αR2,is frequently constrained by its adverse effects.Topical FNS formulations can mitigate adverse effects but often exhibit limited dermal permeability.Nanocarriers show great potential in augmenting the cutaneous permeation of loaded FNS due to their inherent properties of selective accumulation within the hair follicles(HFs).In this study,hollow mesoporous silica nanoparticles(HMSN)with varying sizes were utilized as the nanocarriers for FNS,following mixing with the Carbopol hydrogel(F@H/Gel)for direct topical application.Specifically,the influence of size on the targeted delivery of FNS to HFs,and its enhanced therapeutic efficacy for the AGA mice model was evaluated.Results showed that the HMSN,with a diameter of approximately 300 nm,exhibited significant enhancement in FNS retention within skin and HFs,as well as remarkably accelerated hair regrowth on an AGA mouse model.In conclusion,this FNS topical formulation has proved to be a viable approach in offering a secure and efficient treatment modality for AGA.
文摘Background:Androgenetic alopecia(AGA)is a common hair loss disorder that significantly affects patient’s quality of life.Botulinum toxin(BoNT)has emerged as a potential treatment;however,its effectiveness and underlying mechanisms remain unclear.This systematic review aimed to synthesize the existing evidence on BoNT for AGA,analyze its mechanisms,evaluate its efficacy,and explore its potential for precision therapy.Methods:A PubMed search was conducted for studies published between 2020 and 2025.A total of 25 studies,including 11 clinical trials and 7 reviews,were included.The studies were analyzed for BoNT mechanisms in AGA,treatment regimens,efficacy,outcomes,cost-effectiveness,and safety profiles.Results:Experimental evidence suggests that BoNT reduces transforming growth factor-βin dermal papilla cells,a key pathological pathway in AGA.Other hypothetical mechanisms,such as scalp muscle relaxation improving microcirculation or inhibiting androgen conversion require further validation.In clinical trials,most studies used 30-150 U of BoNT via intramuscular(six studies)or intradermal(three studies)injections,with 1-3 sessions and up to 6 months of follow-up.Early open-label trials reported response rates of 70%-79%,but recent high-quality randomized controlled trials(RCTs)showed no significant improvement in hair density compared to placebo.Combination therapy with finasteride or minoxidil enhanced treatment outcomes,though large-scale evidence is lacking.BoNT was less cost-effective than first-line therapies such as minoxidil,with session costs approximately 37 times higher.Intramuscular injection appeared more effective than intradermal injection,possibly due to scalp muscle relaxation and vascular decompression.BoNT generally had a mild safety profile.Conclusion:Currently,BoNT lacks robust evidence to replace traditional treatments for AGA.Future research should focus on establishing standardized dosing protocols,conducting large-scale,long-term RCTs,and integrating molecular biomarkers to improve understanding and optimize the clinical use of BoNT in AGA management.

文摘BACKGROUND Androgenetic alopecia(AGA)is a common form of hair loss that can be influenced by psychological factors.AIM To investigate the impact of mental stress on neurotrophic factors in patients with AGA and correlate the findings with the progression of AGA.METHODS A total of 120 patients with AGA were analyzed in this study,which were divided into a non-stress group(n=30)and a stress group(n=90)on the basis of the presence or absence of psychological stress confirmed by Depression Anxiety Stress Scale-21 scale.The baseline demographic characteristics,serum cortisol levels,hair growth parameters,neurotrophic factors,and AGA progression scores between the non-stress and stress groups were compared.Correlation analyses were conducted to assess the relationships among stress,neurotrophic factors,hair loss progression,and AGA progression.RESULTS This study revealed significantly higher cortisol levels throughout the day in the stress group than in the non-stress group.The stress group exhibited lower levels of nerve growth factor,brain-derived neurotrophic factor,and glial cell linederived neurotrophic factor and higher expression levels of neurotrophin(NT)-3 and NT-4 than the non-stress group.Hair parameters indicated lower hair diameter,decreased hair density,and more severe AGA grading in the stress group,whereas follicle count and terminal/vellus hair ratio showed no significant differences between the two groups.After 1 year of treatment with 5%minoxidil,efficacy was observed to be lower but AGA progression was notably more pronounced in the stress group than in the non-stress group.Disease progression was positively correlated with high stress and NT-4 levels.CONCLUSION This study provides compelling evidence of the influence of mental stress on neurotrophic factors and its correlation with the progression of AGA.The findings underscore the need for a comprehensive approach to the management of AGA that considers the physiological and psychosocial aspects.Further research is warranted to validate the findings and explore targeted therapeutic interventions for individuals with stress-related AGA.
文摘Androgenic alopecia, also known as seborrheic alopecia, is the most common hair loss disorder in dermatology clinics, mainly characterized by hair follicle miniaturization and progressive hair loss. The etiology and pathogenesis of androgenic alopecia are not clear, but may be related to heredity and androgen metabolism. Currently, minoxidil and finasteride are the only two drugs approved by the U.S. Food and Drug Administration (FDA) for AGA treatment, other treatments include oral minoxidil, hair transplantation, low energy laser therapy (LLLT), platelet-rich plasma (PRP), Chinese medicine microneedles, and combination therapy. With the development of medicine and science, we have ushered in the era of biologics and targeted therapy. In recent years, a variety of signaling pathways for androgenic alopecia have been found, which may provide a basis for targeted therapy for androgenic alopecia.
文摘Introduction: Mechanism of male androgenic alopecia (MAGA) is complex and leads to an excessive hair shedding and decreased hair density. Oral, topical, and injectable autologous treatments demonstrate ability to stimulate hair re-growth, but the response is suboptimal or plateaus off. Synthetic combination of the peptide complex and hyaluronic acid (P-HA) demonstrated hair regrowth in alopecia patients. Electronically-operated pneumatic injections (EPI) generate micro-trauma in the dermis and under wound-healing conditions may enhance regeneration effect of P-HA. Methods: Subjects seeking improvement of their male pattern hair loss (Hamilton-Norwood type 2-4) received the P-HA treatments through EPI. The course included 4 treatments every two weeks over the 8-week period. In 6 months, the hair growth was assessed comparative to baseline by global clinical photography and digital phototrichograms. The treatment safety and tolerability were documented through the whole study period. Results: Twelve men (30-45 years old) completed the treatment course with high tolerability and without adverse events. Post-treatment assessment of the previously bald areas showed improved coverage on the clinical photographs. The phototrichograms demonstrated statistically significant increase in terminal hair density by 36%, cumulative hair thickness by 37%, and follicular units by 20%;all contributing to a 38% increase in cumulated hair density (all p Conclusion: Electronic pneumatic injections are well tolerated and can be safely used for the needle-free administration of the peptide-hyaluronic acid combination in MAGA therapy. We achieved significant hair re-densification in the balding scalp. The exact role of the EPI-induced impact in the hair re-growth mechanism remains to be ascertained. .

文摘Objective To observe the clinical efficacy of catgut embedment combined with moxibustion and bloodletting in the treatment of androgenic alopecia and to probe into its therapeutic mechanism. Methods Eighty-four patients with androgenic alopecia were divided into catgut embedment group （group A） and western medicine group （group B） on the basis of random number table and according to the order of treatment. For the pateints in group A, Shenguan （肾关） on both sides, Minghuang （明黄） and Zusanli （足三里 ST 36） were selected to receive catgut embedment therapy, once every month, combined with moxibustion on the lower abdomen and local bloodletting treatment. For the patients in group B, finasteride 1mg/d was orally administrated. The treatment period for two groups was 3 months, and the follow-up visit lasted for 3 months. Serum testosterone （T） and estradiol （E2） contents were detected respectively before treatment, after i month and 3 months of treatment and after 3 months of follow-up visit, and the specific values were calculated to make statistical analysis of T, E2, T/E2 and curative effects of the two groups after i month and 3 months of treatment and after 3 months of follow-up visit. Results There was no statistical significance in curative effect between the two groups after i month of treatment （P〉0.05）, and the curative effect in group A were better than that in group B after 3 months of treatment or after 3 months of follow-up visit （both P〈0.05）; E2 level in group A was lower than that in group A after 3 months of treatment （P〈0.05）; T, E2 and T/E2 in group A were all lower than that in group B after 3 month of follow-up visit （all P〈0.05）. Conclusion The curative effect of treating androgenic alopecia with catgut embedment, moxibustion and bloodletting is definite, and its mechanism of action may be related to the reduction of T levels and T/E2 values.
文摘Syphilitic alopecia (SA) is a rare skin manifestation in secondary syphilis and sometimes indistinguishable from other alopecia. SA is of 2 types, symptomatic and essential, and 3 clinical types, moth-eaten or patchy pattern, diffuse pattern and a combination of both. SA in our case indicated symptomatic SA with moth-eaten hairloss. A 46-year-old Japanese homosexual man experienced hairloss followed by the pruritic skin rash. Physical examination of the scalp showed diffusely spread papulosquamous erythema and incomplete hairloss around the lesions. The scalp lesions appeared as “moth-eaten alopecia”. Serological examination for syphilis and HIV were positive. Thus, SA complicated with HIV infection was diagnosed. He was treated with a single perioral dose of ampicillin for 4 weeks, then his condition improved rapidly and hair regrowth occurred. HIV-infected persons show a high incidence of syphilis. Therefore, HIV test should be considered for patients with alopecia.
文摘As life pace becomes faster and working pressure gets bigger, incidence of alopecia areata （AA） also increases. The susceptible population presents a trend of getting younger and more diversified. Medical workers in clinic and scientific researchers home and aboard conduct plenty of clinical practices and experimental researches, thus it brings about a lot of new methods, techniques, and theories for treatment of AA. But the effect varies a lot. Therefore, the review summarizes diverse methods and techniques domestic in recent ten years in order to enhance the clinical effect on treatment of AA with acupuncture.

文摘BACKGROUND Alopecia areata is a hair loss disease associated with genetics,autoimmunity,and other factors.There is an intriguing link between alopecia areata and gut dysbiosis.Fecal microbiota transplantation(FMT)has been recommended to treat Clostridium difficile(previously known as Clostridioides difficile)infection,and has also shown potentials in the treatment of inflammatory bowel disease,irritable bowel syndrome,and non-alcohol fatty liver disease.CASE SUMMARY An 86-year-old man,with a history of sigmoid colon carcinoma,suffered from recurrent abdominal pain and distension,and diarrhea for six months,with inappetence.At admission,he was also diagnosed with depression.Upon physical examination,the patient presented with a 1.5 cm×2.0 cm alopecia areata on his right occiput.Due to the negative results of laboratory testing,capsule endoscopy,and colonoscopy,the patient was diagnosed with noninfectious diarrhea,depressive disorder,and patchy alopecia areata.Considering that noninfectious diarrhea in the elderly patient was mainly caused by gut dysbiosis,he was given six rounds of FMT.His diarrhea improved remarkably one month after FMT,with improved appetite and disappearance of abdominal pain,distension,and depressive symptoms.Surprisingly,he reported new hair growth on the affected region of his scalp,with some of his white hair gradually turning to black,without taking any other therapies for alopecia areata before and after FMT.CONCLUSION FMT might act as a potential therapy for patients who suffer from alopecia areata.Large and well-designed studies are required to confirm the role of FMT in alopecia areata.
文摘Alopecia areata is a disease of the hair follicles, with strong evidence supporting autoimmune etiology. Alopecia areata is frequently associated with immune-medi- ated diseases with skin manifestations such as psoriasis and lichen planus, or without skin manifestations such as autoimmune thyroiditis and idiopathic thrombocytopenic purpura. Helicobacter py/ori （H. pylorl） infection is present in around 50% of the world＇s population and has been associated with a variety of immune-mediated extra-digestive disorders including autoimmune thyroid- itis, idiopathic thrombocytopenic purpura, and psoriasis. A case of a 43-year old man with an 8-too history of alopecia areata of the scalp and beard is presented. The patient was being treated by a dermatologist and had psychiatric support, without any improvement. He had a history of dyspepsia and the urea breath test confirmed H. pylori infection. The patient went into remission from alopecia areata after H. pylori eradication. If such an association is confirmed by epidemiological studies designed for this purpose, new therapeutic options could be available for these patients, especially in areas where infection with H, pylori is highly prevalent.
文摘BACKGROUND Alopecia areata(AA)is a common autoimmune disease characterized by hair loss.AA appears in extensive forms,such as progressive and diffusing hair loss(diffuse AA),a total loss of scalp hair(alopecia totalis),and complete loss of hair over the entire body(alopecia universalis).Recently,mesenchymal stem cells(MSCs)have been identified as a therapeutic alternative for autoimmune diseases.For this reason,preclinical and case studies of AA and related diseases using MSCs have been conducted.CASE SUMMARY Case 1:A 55-year-old woman suffered from AA in two areas of the scalp.She was given 15 rounds of minimally manipulated umbilical cord-MSCs(MM-UC-MSCs)over 6 mo.The AA gradually improved 3 mo after the first round.The patient was cured,and AA did not recur.Case 2:A 30-year-old woman,with history of local steroid hormone injections,suffered from AA in one area on the scalp.She was given two rounds of MM-UC-MSCs over 1 mo.The AA immediately improved after the first round.The patient was cured,and AA did not recur.Case 3:A 20-year-old woman,who was diagnosed with alopecia universalis at the age of 12,was given 14 rounds of MM-UC-MSCs over 12 mo.Her hair began to grow about 3 mo after the first round.The patient was cured,and alopecia universalis did not recur.CONCLUSION MM-UC-MSC transplantation potentially treats patients who suffer from AA and related diseases.

文摘In the current study, the alopecia areata gene was introduced into the C57BL/6 （B6） mouse through repeated backcrossing/intercrossing, and the allelic homozygosity of congenic AAtJmice （named B6.KM-AA） was verified using microsatellites. The gross appearance, growth characteristics, pathological changes in skin, and major organs of B6.KM-AA mice were observed. Counts and proportions of CD4＋ and CD8＋ T lymphocytes in peripheral blood were determined by flow cytometry. Results show that congenic B6.KM-AA mice were obtained after 10 generations of backcrossing/intercrossing. B6.KM-AA mice grew slower than B6 control mice and AA skin lesions were developed by four weeks of age. The number of hair follicles was reduced, but hair structures were normal. Loss of hair during disease progression was associated with CD4＋ and CD8＋ T lymphocytes infiltration peri- and intrahair follicles. No pathological changes were found in other organs except for the skin. In the peripheral blood of B6.KM-AA mice, the percentage of CD4＋ T cells was lower and percentage of CD8＋ T cells higher than in control mice. These findings indicate that B6.KM-AA mice are characterized by a dysfunctional immune system, retarded development and T-cell infiltration mediated hair loss, making them a promising new animal model for human alopecia areata.
文摘Androgens have an intense consequence on the human scalp and body hair.Scalp hair sprouts fundamentally in awol of androgens whereas the body hair hike is vulnerable to the activity of androgens.Androgenetic alopecia(AGA)invoked as males emulate Alopecia due to the cause of the dynamic reduction of scalp hair.Androgens are medium of terminus growth of hair although the body.Local and system androgens convert the extensive terminal follicles into lesser vellus like structure.The out start of this type of alopecia is intensely irregular and the reason behind this existence of enough circulating steroidal hormones androgens and due to genetic predisposition.Effective treatments are available in the market as well as under clinical and preclinical testing.Many herbal formulations are also available but not FDA approved.Different conventional and NDDS formulations are already available in the market.To avoid various systemic side effects of both Finasteride and Minoxidil,topical formulations and natural products(nutrients,minerals,vitamins)now a days are being widely used to treat Androgenic alopecia.CAM(complementary and alternative medicine)provides the option to elect favorable,low-risk,adjuvant and alternative therapies.Herein,we offer a widespread review of topical marketed formulations,natural products,and CAM treatment options for AGA.

文摘A male,62 years old,suffering from alopecia universalis,was treated with acupuncture.The treating principle was promoting qi and blood circulation.The selected acupoints included Bǎihui(百会GV20),Tàiyáng(太阳EX-HN5),Fengmen(风门BL12),Xīnshū(心俞BL15),Ganshū(肝俞BL18),Shenshū(肾俞BL23),etc.After treated for 3 months,the hair was grown normally and the hair on the scalp got black obviously.In the follow-up for 2 months,the hair on the body and scalp grew in good condition.
文摘Qigong is a part of traditional Chinese medicine. According to the antique treaties, the foundations of traditional Chinese medicine are based in maintaining the harmony between Qi (energy), Jing (essence) and Shen (spirit). Alterations in this harmony can develop and determine the appearance of disease. Therapeutic effects of Qigong are helpful in the prevention and treatment of several diseases. It's main role in restoring body functions is due to the communication between internal organs, tissues and cells. The main goal of this work is to show the efficacy of Qigong in the treatment of a dermatological disease characterized by the appearance of circular or oval patches of missing hair, known as alopecia universalis. For western medicine the exact cause of this illness is not totally revealed, however, it's attributed to psycological, genetics and metabolic alterations. From the traditional Chinese medicine perspective, hair alterations are framed in the area of the water energy, represented by the kidney organ. The results of Qigong treatment suggested that the cranial hair follicles had been activated since the first treatment. As treatment progressed, the cranial hair follicles continued to grow, what's more, the brightness and pigmentation of the hair also increased. Therefore, in the clinical conditions evaluated, Qigong could be an effective alternative treatment in consideration of the visible evidence about rapid and long lasting results. Besides, we did not observe any side effects of Qigong in this case.
