Drying is a complex operation that demands much energy and time. Drying is essentially important for preservation of ginger rhizome. Drying of ginger was modeled, and then the effective diffusion coefficient and activation energy were determined. For this purpose, the experiments were done at six levels of varied temperatures: 10°C, 20°C, 30°C, 40°C, 50°C and 60°C. The values of effective diffusion coefficients obtained in this work for the variously treated ginger rhizomes closely agreed with the average effective diffusion coefficients of other notable authors who determined the drying kinetics and convective heat transfer coefficients of ginger slices.展开更多

Methods: Sixty postoperative breast cancer patients undergoing chemotherapy were randomly divided into an observation group and a control group, with 30 patients in each group. The control group received antiemetic treatment with dolasetron, while the observation group received ginger slice acupoint application combined with moxibustion in addition to antiemetic treatment to address chemotherapy-induced vomiting. The vomiting response on days 1-3 was compared between the two groups, along with R-INVR retching scores and patient satisfaction with the intervention methods. Results: On days 2 and 3 of chemotherapy, the observation group showed significantly less vomiting than the control group, with differences reaching a highly significant level (P < 0.001). On day 3, the R-INVR score in the observation group was significantly lower than that of the control group, with a highly significant difference (P < 0.001). The satisfaction score in the observation group was 8.38 ± 0.81, higher than the control group’s 7.65 ± 0.71, with a statistically significant difference (P < 0.05). Conclusion: Ginger slice acupoint application combined with moxibustion effectively alleviates chemotherapy-induced vomiting in postoperative breast cancer patients, improves quality of life, and is worth promoting clinically.展开更多

Methods: Effect of a commonly used herbal product and ginger(Zingiber officinale) towards protoscoleces(PSC) and cyst wall in vitro was studied. The effect of [6]-gingerol, and the pungent constituent of ginger, was also evaluated on PSC culture. Furthermore, the activity of both extracts in association with interferon-gamma(IFN-γ) on PSC co-cultured with mononuclear cells of hydatic patients was evaluated. The nitric oxide(NO) production was measured in each co-culture. Results: Ginger exhibited a concentration- and time-dependent cytotoxic effect against PSC and cyst wall. Interestingly, ginger was more effective than the [6]-gingerol. Moreover, additional parasitic effect between extracts and IFN-γ are also observed in co-cultures. Furthermore, both extracts attenuated the NO production elicited by this infection or by the IFN-γ. Conclusions: Ginger has an important anti-hydatic effect in vitro. This effect is amplified in the presence of IFN-γ. Moreover, this herbal product may protect against host's cell death by reducing the high levels of NO. Ginger may act, at least, through the [6]-gingerol. All our data suggest the promising use of ginger in the treatment of Echinococcus granulosus infection.展开更多

In the present study, the effect of ginger （rhizome of Zingiber officinale Roscoe） volatile oil on a rat model of colitis was evaluated. METHODS： Volatile oil of ginger with doses of 100, 200, and 400 mg/kg, prednisolone （4 mg/kg）, or vehicle were administered orally to groups of male Wistar rats （n = 6） for 5 d. Animals were randomly divided into 6 groups, each group consisting of 6 rats. Colitis was induced by intracolonic instillation of 2 mL of 4% （v/v） acetic acid solution. All rats were sacrificed 24 h later and the tissue injuries were assessed macroscopically and histopathologically. RESULTS： Ginger volatile oil with all doses reduced colon weight/length ratio （P 〈 0.01） and the effects were similar to the reference drugs. Higher oral doses of volatile oil （200 and 400 mg/kg） reduced ulcer severity （P 〈 0.05 and P 〈 0.01）, ulcer area （P 〈 0.01） and ulcer index （P 〈 0.01）. On the other hand, evaluation of microscopic scores showed that the dose of 400 mg/kg of volatile oil was effective to reduce inflammation severity （P 〈 0.01） and inflammation extent （P 〈 0.05） compared to the control group. CONCLUSION： It is concluded that ginger volatile oil could effectively reduce symptoms of experimental colitis in a dose-dependent manner.展开更多

文摘Dynamic changes in the physiochemical,structural,and flavor characteristics of ginger-juice milk curd were explored by texture analysis,scanning electron microscopy,rheometry,electronic tongue,and gas chromatography-mass spectrometry(GC-MS).Protein electrophoresis showed that ginger juice could hydrolyzeαs-,β-,andκ-casein.Curd formation was initiated at 90 s,marked by significant changes in intensity detected via intrinsic fluorescence.The contents of soluble protein and calcium decreased rapidly during coagulation,while the caseinolytic activity,storage moduli,loss moduli,hardness,adhesiveness,and water-holding capacity increased,resulting in a denser gel structure with smaller pores and fewer cavitations as observed by scanning electron microscopy.Electronic tongue analysis indicated that milk could neutralize the astringency and saltiness of ginger juice,rendering the taste of ginger-juice milk curd more akin to that of milk.Approximately 70 volatile components were detected in ginger-juice milk curd.α-Zingiberene,α-curcumene,β-sesquiphellandrene,andβ-bisabolene were the predominant volatile flavor compounds,exhibiting an initial decrease in content followed by stability after 90 s.Decanoic acid,γ-elemene,and caryophyllene were identified as unique volatile compounds after mixing of milk and ginger juice.Understanding the dynamic changes in these characteristics during coagulation holds significant importance for the production of ginger-juice milk curd.

文摘Vein graft(VG)failure(VGF)is associated with VG intimal hyperplasia,which is characterized by abnormal accumulation of vascular smooth muscle cells(VSMCs).Most neointimal VSMCs are derived from pre-existing VSMCs via a process of VSMC phenotypic transition,also known as dedifferentiation.There is increasing evidence to suggest that ginger or its bioactive ingredients may block VSMC dedifferentiation,exerting vasoprotective functions;however,the precise mechanisms have not been fully characterized.Therefore,we investigated the effect of ginger on VSMC phenotypic transition in VG remodeling after transplantation.Ginger significantly inhibited neointimal hyperplasia and promoted lumen(L)opening in a 3-month VG,which was primarily achieved by reducing ferroptotic stress.Ferroptotic stress is a pro-ferroptotic state.Contractile VSMCs did not die but instead gained a proliferative capacity and switched to the secretory type,forming neointima(NI)after vein transplantation.Ginger and its two main vasoprotective ingredients(6-gingerol and 6-shogaol)inhibit VSMC dedifferentiation by reducing ferroptotic stress.Network pharmacology analysis revealed that 6-gingerol inhibits ferroptotic stress by targeting P53,while 6-shogaol inhibits ferroptotic stress by targeting 5-lipoxygenase(Alox5),both promoting ferroptosis.Furthermore,both ingredients co-target peroxisome proliferator-activated receptor gamma(PPARγ),decreasing PPARγ-mediated nicotinamide adenine dinucleotide phosphate(NADPH)oxidase 1(Nox1)expression.Nox1 promotes intracellular reactive oxygen species(ROS)production and directly induces VSMC dedifferentiation.In addition,Nox1 is a ferroptosis-promoting gene that encourages ferroptotic stress production,indirectly leading to VSMC dedifferentiation.Ginger,a natural multi-targeted ferroptotic stress inhibitor,finely and effectively prevents VSMC phenotypic transition and protects against venous injury remodeling.

文摘Background:Exploring the efficacy,potential components,and mechanism of the combination of ginger essential oil and gingerols in the treatment of head wind disease based on network pharmacology technology with content weight.Methods:The experimental groups were divided into:0:10,1:4,1:2,1:1,2:1,4:1,10:0.The relative content(Ri)of the chemical constituents of ginger's volatile oil was determined using gas chromatography-mass spectrometry(GC-MS).Additionally,the physicochemical and biological property parameters(LogP,MDCK,PPB,MW)of the components were considered.To assess the quantitative effect of the components,a grading score was performed,and the quantitative effect index(Ki)was calculated.Subsequently,the target effect index(Ti)was calculated by combining the component-target matching score(Fit score).Using these calculations,the target effect score A was determined under the influence of multiple components targeting different targets.Key targets with A≥1000 were identified.To predict the targets related to head wind disease,the Comparative Toxicogenomics Database(https://ctdbase.org/),Gene Cards(https://www.genecards.org/),and Disgenet database(https://www.disgenet.org/)were utilized.The key targets,obtained from different proportions of ginger's volatile oil and gingerol,were intersected with the predicted targets.This facilitated network pharmacological analysis and verification of the efficacy.Results:The content of volatile oil in ginger demonstrated an impact on key targets associated with the volatile oil group.Each specific combination of volatile oil consistently activated distinct pathways,with variations stemming from changes in content.Experimental testing revealed that different combinations of ginger's volatile oil and gingerol effectively alleviated migraine symptoms in rats.Conclusion:Through the application of content-weighted network pharmacology technology and pharmacodynamic verification,it was determined that altering the ratio between ginger's volatile oil and gingerol leads to variations in potential targets and pathways,consequently impacting its efficacy.
文摘This study is an extension of the previous work done with ARS-680 Environmental Chamber. Drying is a complex operation that demands much energy and time. Drying is essentially important for preservation of ginger rhizome. Drying of ginger was modeled, and then the effective diffusion coefficient and activation energy were determined. For this purpose, the experiments were done at six levels of varied temperatures: 10°C, 20°C, 30°C, 40°C, 50°C and 60°C. The values of effective diffusion coefficients obtained in this work for the variously treated ginger rhizomes closely agreed with the average effective diffusion coefficients of other notable authors who determined the drying kinetics and convective heat transfer coefficients of ginger slices.
文摘Objective:Menstrual blood-derived stem cells from endometriosis patients(E-MenSCs)have different gene expression patterns than those from healthy nonendometriotic females(NE-MenSCs).Exosomes extracted from mesenchymal stem cells and plants are considered for the treatment of various diseases.This study aimed to compare the effects of exosomes derived from NE-MenSCs(C-exos)and those from the roots of ginger(P-exos)on E-MenSCs.Methods:E-MenSCs at the third passage were used,and after evaluating the effective dosage with MTT,C-exos(200µg/mL)or P-exos(100µg/mL)were added to treat them.Following a 72-h incubation,the cells were analyzed with annexin V/PI test to evaluate the apoptosis rate.Also,genes related to inflammation(IL-6,IL-8,IL-1β,NF-κB,COX2),cell cycle(Cyclin D1),the steroid pathway(ESR1),migration and invasion(MMP-2,MMP-9,VEGF),and the apoptosis pathway(BAX,BCL2)were detected by real-time PCR.Results:Apoptosis was increased in both the P-and C-exos groups.The expression levels of IL-6 and IL-1βwere significantly lower in the P-exos group than in the E-MenSCs group.The expression levels of IL-8,NF-κB,COX-2,and MMP-9 were significantly decreased in both the P-exos group and the C-exos group.The expression level of VEGF was significantly lower in the P-exos group than in the E-MenSCs group.The BAX/BCL2 ratio was much lower in the P-exos group than in the E-MenSCs group.Conclusion:In this study,we established the feasibility of using a novel natural nontoxic material to target endometriotic mesenchymal stem cells to modify their gene expression and function toward healthy cells.Both C-exos and P-exos showed positive effects on the gene expression and function of endometriotic cells.Considering that plant exosomes are easier to access and less expensive,they can be considered for clinical use in improving the symptoms of endometriosis patients.
文摘Objective: To investigate the effect of ginger slice acupoint application combined with moxibustion on chemotherapy-induced vomiting in postoperative breast cancer patients. Methods: Sixty postoperative breast cancer patients undergoing chemotherapy were randomly divided into an observation group and a control group, with 30 patients in each group. The control group received antiemetic treatment with dolasetron, while the observation group received ginger slice acupoint application combined with moxibustion in addition to antiemetic treatment to address chemotherapy-induced vomiting. The vomiting response on days 1-3 was compared between the two groups, along with R-INVR retching scores and patient satisfaction with the intervention methods. Results: On days 2 and 3 of chemotherapy, the observation group showed significantly less vomiting than the control group, with differences reaching a highly significant level (P < 0.001). On day 3, the R-INVR score in the observation group was significantly lower than that of the control group, with a highly significant difference (P < 0.001). The satisfaction score in the observation group was 8.38 ± 0.81, higher than the control group’s 7.65 ± 0.71, with a statistically significant difference (P < 0.05). Conclusion: Ginger slice acupoint application combined with moxibustion effectively alleviates chemotherapy-induced vomiting in postoperative breast cancer patients, improves quality of life, and is worth promoting clinically.

文摘Objective: To study in vitro anti-hydatic and immunomodulatory effects of ginger and [6]-gingerol as an alternative therapy for Cystic echinococcosis. Methods: Effect of a commonly used herbal product and ginger(Zingiber officinale) towards protoscoleces(PSC) and cyst wall in vitro was studied. The effect of [6]-gingerol, and the pungent constituent of ginger, was also evaluated on PSC culture. Furthermore, the activity of both extracts in association with interferon-gamma(IFN-γ) on PSC co-cultured with mononuclear cells of hydatic patients was evaluated. The nitric oxide(NO) production was measured in each co-culture. Results: Ginger exhibited a concentration- and time-dependent cytotoxic effect against PSC and cyst wall. Interestingly, ginger was more effective than the [6]-gingerol. Moreover, additional parasitic effect between extracts and IFN-γ are also observed in co-cultures. Furthermore, both extracts attenuated the NO production elicited by this infection or by the IFN-γ. Conclusions: Ginger has an important anti-hydatic effect in vitro. This effect is amplified in the presence of IFN-γ. Moreover, this herbal product may protect against host's cell death by reducing the high levels of NO. Ginger may act, at least, through the [6]-gingerol. All our data suggest the promising use of ginger in the treatment of Echinococcus granulosus infection.

文摘In order to establish high-yield and high-efficient cultivation technology for ginger in the central region of Shandong Province, the effects of different manage-ment modes on yield of ginger, nutrient efficiency and soil nitrate were carried out by field experiment. Four management modes were farmer convention mode, high yield and high efficiency mode, super high yield mode and super high yield and high efficiency mode, in which farmer convention mode was local farmers ’ conven-tional cropping methods, the other three management modes were optimized combi-nations of al management measures under a certain goal of increasing yield and efficiency. The results were as fol ows： ginger yield and nitrogen fertilizer efficiency under such three optimized management measures combinations as high yield and high efficiency mode, super high yield mode and super high yield and high efficien-cy mode were al higher than these of farmer convention mode, moreover, com-pared with farmer convention mode, the yield increased by 11.85%, 25.75% and 23.34%, respectively, and nitrogen fertilizer efficiency increased by 47.94%, 11.24%and 33.14%, respectively. Thereinto, the yield under super high yield mode were the greatest,and nitrogen fertilizer efficiency under high yield and high efficiency mode was the highest.
文摘Ginger(Zingiber officinale Roscoe)has high economic value as medicinal and food resources.6-gingerol is the core medicinal constituents of ginger.In the present study,a local ginger cultivar of Chongqing was taken as the research material.The ZoWRKY1 gene was cloned to determine its expression level in different ginger developmental phases and to analyze its correlation with 6-gingerol content.The expression level of ZoWRKY1 under different concentrations of NaCl stress was tested,and so was the correlation between ZoWRKY1’s expression level and the contents of 6-gingerol synthase genes,i.e.ZoPAL,ZoC4H and Zo4CL.The results showed that the cDNA of the cloned ZoWRKY1 gene is 1026 bp in total length,and ZoWRKY1 belongs to the second type member of the WRKY family;the expression level of ZoWRKY1 rose sharply in the second developmental phase of the ginger which was about one month after sowing,and there was a significant correlation between the expression level of ZoWRKY1 and the increase of 6-gingerol content;the expressions of ZoWRKY1 and 6-gingerol synthase genes ZoPAL,ZoC4H and Zo4CL had sharp rises under 25 g/L NaCl stress,and the expression level of ZoWRKY1 was closely related to that of ZoC4H or Zo4CL.Therefore,it was speculated that there was a regulatory correlation between ZoWRKY1 and ZoC4H or Zo4CL that can further affect the biosynthesis of 6-gingerol.

文摘OBJECTIVE： Ulcerative colitis is a chronically recurrent inflammatory bowel disease of unknown origin. In the present study, the effect of ginger （rhizome of Zingiber officinale Roscoe） volatile oil on a rat model of colitis was evaluated. METHODS： Volatile oil of ginger with doses of 100, 200, and 400 mg/kg, prednisolone （4 mg/kg）, or vehicle were administered orally to groups of male Wistar rats （n = 6） for 5 d. Animals were randomly divided into 6 groups, each group consisting of 6 rats. Colitis was induced by intracolonic instillation of 2 mL of 4% （v/v） acetic acid solution. All rats were sacrificed 24 h later and the tissue injuries were assessed macroscopically and histopathologically. RESULTS： Ginger volatile oil with all doses reduced colon weight/length ratio （P 〈 0.01） and the effects were similar to the reference drugs. Higher oral doses of volatile oil （200 and 400 mg/kg） reduced ulcer severity （P 〈 0.05 and P 〈 0.01）, ulcer area （P 〈 0.01） and ulcer index （P 〈 0.01）. On the other hand, evaluation of microscopic scores showed that the dose of 400 mg/kg of volatile oil was effective to reduce inflammation severity （P 〈 0.01） and inflammation extent （P 〈 0.05） compared to the control group. CONCLUSION： It is concluded that ginger volatile oil could effectively reduce symptoms of experimental colitis in a dose-dependent manner.
