Material and Methods: An observational retrospective study was conducted on intoxicated patients who admitted to ICU between January 2022 and January 2024. Data were collected from the patients medical records. The demographic characteristics, causes of intoxications, clinical parameters, the mean stay in the ICU, treatment modalities and prognosis were recorded. Results: A total of 2875 critically ill patients were admitted during the study period, and 109 (3.79%) of them were acute intoxications. Their mean of ages was 38.09 ± 12.29. The female-to-male ratio was 1.37/1. Drugs were found to be the primary cause (62.39%) of intoxications, and analgesics, antidepressants, and antibiotics were the most frequent agents. Suicidal attempts were present in 66 patients, most of them were female (62.13%) and between 17 - 24 years (40.91%). The other common causes of intoxications were carbon monoxide (CO) (22.02%), methyl/ethyl alcohol (8.26%) and mushroom (5.50%). The mean stay in the ICU was 2.69 ± 0.89 days. Mechanical ventilation was applied to 10 of our patients. Renal replacement therapy was required in 6 patients. Despite all treatments, 6 of our patients died, and we found the mortality rate to be 5.50%. Conclusion: Intoxications were more frequent in young female patients and drugs were the most common cause with suicidal intent. Unfortunately, CO poisoning continues to be a very important problem in our city. These findings provided significant information about the characteristics of intoxications in Karabuk.展开更多

[Method] Acute alcohol intoxication was induced by administering alcohol to mice. Three different doses (low, middle and high) of compound of traditional Chinese drugs were administered to mice before and after administering alcohol respectively to investigate the preventive and therapeutical effect of drugs on acute alcohol intox-ication through doing statistical analysis about drunk mice and their sleeping time. The concentration of malondialdehyde (MDA), reduced glutathione (GSH) and triglyc-erides (TG) in liver was also determined to investigate the protective effect of drugs on liver. [Result] The efficacy of compound of traditional Chinese drugs on acute al-cohol intoxication was dose-dependent. High-dose administration decreased the number of drunk mice significantly compared with control group; middle- and high-dose administration reduced the sleeping time of drunk mice and the concentration of MDA and TG in liver tissue; three doses al increased the concentration of GSH. [Conclusion] The compound of Japanese raisintree fruit, lobed kudzuvine flower bud and lightyel ow sophora root had preventive and therapeutical effect on hangover, and it also had certain preventive and therapeutical effect on liver damage caused by alcohol.展开更多

Methods: Seventy-six randomly selected volunteer drivers each had three times of alcohol intake (100 ml each time). After each drank, BAC was measured with gas chromatograph and driving ability was evaluated. The drivers were grouped according to age, weight, alcohol tolerance and driving experience respectively and changes in BAC and driving ability were analyzed. Results: Average BAC and the percentage of drivers showing impaired driving ability in the groups increased after each intake of 100 ml alcohol. BAC in Group≤60 kg was more susceptible to alcohol than that in Group>60 kg. When each drank, alcohol had greater influence on drivers who had comparatively shorter driving experience. Conclusion: Volume of consumed alcohol, BAC and driving ability have direct associations among one another and are all under the influence of various factors including individual conditions. To set an appropriate legal BAC limit for safe driving should take an overall consideration of all factors.展开更多

In the environment, there are many hepatotoxic xenobiotics. CCl4 is a free radical toxic for organelles of hepatocytes. The presented work was studying the character of ultrastructural changes in CCl4-intoxicated hepatocytes as well as the tissue after treatment by grape seed extract (GSE), α-tocopherol (α-T). As a result of cell bioremediation effect and reactions against corruptive factors, the liver has a high regeneration ability.展开更多

The diagnosis of mushroom intoxication was based on the following: (1) a positive history of recent wild mushroom intake (either raw or cooked); (2) the onset of gastrointestinal symptoms, such as watery diarrhea, vomiting, and/or abdominal pain, after ingestion; and (3) the exclusion of other possible causes of acute liver injury. Acute liver injury was defined by a > 5-fold elevation of liver enzymes or moderate coagulopathy [international normalized ratio (INR) > 2.0]. Clinical and laboratory findings were compared in survivors and non-survivors.RESULTSOf 93 patients with mushroom intoxication, 23, 11 men (47.8%) and 12 women (52.2%), of median age 61 years, developed acute liver injury. The overall in-hospital mortality rate was 43.5% (10/23). Among the laboratory variables, mean serum alkaline phosphatase (73.38 ± 10.89 mg/dL vs 180.40 ± 65.39 mg/dL, P < 0.01), total bilirubin (2.312 ± 1.16 mg/dL vs 7.16 ± 2.94 mg/dL, P < 0.01) concentrations and indirect/direct bilirubin (2.45 ± 1.39 mg/dL vs 0.99 ± 0.45 mg/dL, P < 0.01) ratio as well as prothrombin time (1.88 ± 0.83 mg/dL vs 10.43 ± 4.81 mg/dL, P < 0.01), and activated partial thromboplastin time (aPTT; 32.48 ± 7.64 s vs 72.58 ± 41.29 s, P = 0.01), were significantly higher in non-survivors than in survivors. Logistic regression analysis showed that total bilirubin concentration (OR = 3.58, 95%CI: 1.25-10.22), indirect/direct bilirubin ratio (OR = 0.14, 95%CI: 0.02-0.94) and aPTT (OR = 1.30, 95%CI: 1.04-1.63) were significantly associated with mortality. All patients with total bilirubin > 5 mg/dL or aPTT > 50 s on day 3 died.CONCLUSIONMonitoring of bilirubin concentrations and aPTT may help in predicting clinical outcomes in patients with acute liver injury from wild mushroom intoxication.展开更多

Massive ischemic tissue necrosis occurs in 0.5%-1% of cases with CO poisoning. The affinity of CO to Hb is 200-250 times more when compared to the affinity of oxygen. As a result of CO binding to Hb, oxygen delivery to the tissues is reduced, and tissue hypoxia develops. This affects mostly the brain and heart, which are the organs with the highest demand for oxygen.展开更多

Recent reports ...Cadmium (Cd), one of the most dangerous heavy metals, has a very similar ionic radius to calcium (Ca). The interference of cadmium in calcium homeostasis may play an important role in cadmium toxicity. Recent reports indicate that calmodulin (CaM) inhibitors such as trifluoperazine and chlorpromazine (CPZ) could protect rodents against cadmium toxicity. It was also reported that pretreatment of mice with zinc (Zn) could reduce the adverse effects induced by cadmium. The aim of this study is to determine whether Cd changes the balance of other essential metals such as Zn and copper (Cu) in rat tissues, and whether CPZ can reverse these changes which are induced by cadmium intoxication. Adult male Sprague Dawley (SD) rats were injected intraperitoneally (ip) with cadmium chloride (CdCl 2) (0.2, 0.4, 0.8 mg Cd/kg body weight) alone and 0.4mg Cd/kg in association with CPZ (5 mg/kg) daily for a week. The control animals were injected with normal saline only. The results showed that the cadmium content in the liver, kidney and testis increased significantly with a dose response relationship. Cadmium treatment markedly increased the Zn and Ca content in some of the tissues. Hepatic and renal metallothionein (MT) increased significantly after cadmium intoxication. CPZ treatment, however, reduced cadmium content in liver, but not blood and kidney. CPZ seemed to decrease the content of MT in liver and significantly increase the amounts of MT in kidney. These data suggest that the intervention of cadmium with tissue essential metals may play a role in cadmium toxicity in rats, and calmodulin inhibitors to some extent can reduce the adverse effect of cadmium by decreasing the cadmium load in tissues and reversing the unbalance of essential metals.展开更多

However, an enormous protection obtained could not be delineated on account of possible in situ binding of α-KG given intraperitoneally (i.p.) in mice to cyanide administered through the same route. The present study was designed to see the efficacy of a-KG alone or in combination with sodium nitrite (SN) and/or sodium thiosulfate (STS) in male mice exposed to cyanide administered through subcutaneous (s.c.) or inhalation route. A technique for generation of hydrogen cyanide (HCN) is also discussed. On the basis of protection index (PI), defined here as the LD50 of cyanide in protected mice/LD50 of cyanide in unprotected mice and survival time, STS + α-KG regimen was equipotent to the conventional SN + STS regimen. This is further substantiated by effect of α-KG in reducing plasma cyanide levels. The efficacy of α-KG remains undeterred irrespective of the route of cyanide intoxication, while the magnitude of protection varies.展开更多

Acute liver failure was realized by intrajejunal acetaminophen administration in six animals, two animals were sham operated. All animals were invasively monitored and received standardized intensive care support throughout the study. Portal blood flow, hemodynamic and ventilation parameters were continuously recorded. Laboratory parameters were analysed every eight hours. Liver biopsies were sampled every 24 h following intoxication and upon autopsy.RESULTSAcute liver failure (ALF) occurred after 28 ± 5 h resulted in multiple organ failure and death despite maximal support after further 21 ± 1 h (study end). Portal blood flow (baseline 1100 ± 156 mL/min) increased to a maximum flow of 1873 ± 175 mL/min at manifestation of ALF, which was significantly elevated (P < 0.01). Immediately after peaking, portal flow declined rapidly to 283 ± 135 mL/min at study end. Thrombocyte values (baseline 307 × 10<sup>3</sup>/µL ± 34 × 10<sup>3</sup>/µL) of intoxicated animals declined slowly to values of 145 × 10<sup>3</sup>/µL ± 46 × 10<sup>3</sup>/µL when liver failure occurred. Subsequent appearance of severe thrombocytopenia in liver failure resulted in values of 11 × 10<sup>3</sup>/µL ± 3 × 10<sup>3</sup>/µL preceding fatality within few hours which was significant (P > 0.01).CONCLUSIONDeclining portal blood flow and subsequent severe thrombocytopenia after acetaminophen intoxication precede fatality in a porcine acute liver failure model.展开更多

The advanced therapeutic tactics were proposed for the patients of both groups. The control group consisted of 40 healthy individuals (donors). BS of these patients was also tested using MFS. <strong>Results: </strong>Patients with burn injury have endogenous intoxication in their blood. The effective concentration of albumin is reduced in patients with burn injury due to the blockage of albumin binding centers by bacterial metabolism products. Fluorescence spectra (FS) of BS in patients with burn trauma and donors were obtained and investigated. Based on MFS results, an improved treatment regimen using infusion of albumin solution was proposed. <strong>Conclusions:</strong> An improved technique for the management of patients with burn injury is based on the use of MFS for the diagnostic evaluation of endogenous intoxication in them. The idea of pathological changes in albumin molecules in patients with burn injury is pathogenetically substantiated by the successful use of infusion of albumin solution in these patients on the basis of the MFS.展开更多

文摘Background: The aim of this study was to evaluate the clinical and epidemiological characteristics of patients with acute intoxication admitted to the Intensive Care Unit (ICU). Material and Methods: An observational retrospective study was conducted on intoxicated patients who admitted to ICU between January 2022 and January 2024. Data were collected from the patients medical records. The demographic characteristics, causes of intoxications, clinical parameters, the mean stay in the ICU, treatment modalities and prognosis were recorded. Results: A total of 2875 critically ill patients were admitted during the study period, and 109 (3.79%) of them were acute intoxications. Their mean of ages was 38.09 ± 12.29. The female-to-male ratio was 1.37/1. Drugs were found to be the primary cause (62.39%) of intoxications, and analgesics, antidepressants, and antibiotics were the most frequent agents. Suicidal attempts were present in 66 patients, most of them were female (62.13%) and between 17 - 24 years (40.91%). The other common causes of intoxications were carbon monoxide (CO) (22.02%), methyl/ethyl alcohol (8.26%) and mushroom (5.50%). The mean stay in the ICU was 2.69 ± 0.89 days. Mechanical ventilation was applied to 10 of our patients. Renal replacement therapy was required in 6 patients. Despite all treatments, 6 of our patients died, and we found the mortality rate to be 5.50%. Conclusion: Intoxications were more frequent in young female patients and drugs were the most common cause with suicidal intent. Unfortunately, CO poisoning continues to be a very important problem in our city. These findings provided significant information about the characteristics of intoxications in Karabuk.

文摘BACKGROUND Bacillus cereus(B.cereus)is known to cause 2 types of foodborne diseases;the diarrheal and emetic syndromes.They are largely underreported due to their usually self-limiting course.Rare and sometimes fatal cases of liver failure,pulmonary hemorrhage and cerebral oedema have been reported mainly in children and young adults.We present here a case of liver failure associated with B.cereus food poisoning in a middle-aged patient.CASE SUMMARY A 48-year-old female patient presented to the emergency department for emesis,diarrhea,chills without fever,asthenia and diffuse abdominal cramps that started less than 30 minutes after eating a rice salad.Her past medical history was relevant for cholecystectomy and a cured Hashimoto’s disease.She did not take any medication,drugs and declared a consumption of one glass of wine per week.In the emergency department,she was treated with acetaminophen,metoclopramide,ondansetron,and an intravenous normal saline infusion.Blood gas analysis revealed a metabolic acidosis with hyperlactatemia,coagulation revealed a low prothrombin activity[32%;normal values(N):70-140]and a low Factor V activity(15%;N:>70).Transaminases were elevated with hyperbilirubinemia,elevated lipase and rhabdomyolysis.N-acetylcysteine treatment was introduced.Abdominal echography revealed no signs of chronic hepatopathy or hepatomegaly.Day after the admission,psychomotor activity improved,transaminases and lipase started decreasing.Rhabdomyolysis gradually worsened to peak on day 3.Screening tests for liver disease were negative for viral and autoimmune cause of liver failure.Stools cultures were positive for colonies of the B.cereus group which were also identified in the rice salad samples processed whereas blood cultures were negative.The patient’s condition improved gradually including her liver function parameters and psychomotor activity which allowed her discharged home on day 9.CONCLUSION We describe a rare case of hepatocellular dysfunction due to a foodborne B.cereus intoxication in an adult patient.Even if it is uncommon,the severity of liver dysfunction reported and mechanism of the cereulide toxin toxicity on liver suggest that acetaminophen should be avoided in case of a foodborne intoxication and n-acetylcysteine could be a potential therapy helping to prevent hepatocytes necrosis due to the oxidative stress induced by mitochondrial dysfunction.

文摘[Objective] We aimed to investigate the preventive and therapeutical effect of compound of traditional Chinese drugs (Japanese raisintree fruit, lobed kudzuvine flower bud and lightyel ow sophora root) on acute alcohol intoxication in mice. [Method] Acute alcohol intoxication was induced by administering alcohol to mice. Three different doses (low, middle and high) of compound of traditional Chinese drugs were administered to mice before and after administering alcohol respectively to investigate the preventive and therapeutical effect of drugs on acute alcohol intox-ication through doing statistical analysis about drunk mice and their sleeping time. The concentration of malondialdehyde (MDA), reduced glutathione (GSH) and triglyc-erides (TG) in liver was also determined to investigate the protective effect of drugs on liver. [Result] The efficacy of compound of traditional Chinese drugs on acute al-cohol intoxication was dose-dependent. High-dose administration decreased the number of drunk mice significantly compared with control group; middle- and high-dose administration reduced the sleeping time of drunk mice and the concentration of MDA and TG in liver tissue; three doses al increased the concentration of GSH. [Conclusion] The compound of Japanese raisintree fruit, lobed kudzuvine flower bud and lightyel ow sophora root had preventive and therapeutical effect on hangover, and it also had certain preventive and therapeutical effect on liver damage caused by alcohol.
文摘Objective: To study the relationship between the amount of consumed alcohol, blood alcohol concentration (BAC), and driving ability among a part of the population in Southwest China and to provide reference for the formulation of the legal limits for safe driving. Methods: Seventy-six randomly selected volunteer drivers each had three times of alcohol intake (100 ml each time). After each drank, BAC was measured with gas chromatograph and driving ability was evaluated. The drivers were grouped according to age, weight, alcohol tolerance and driving experience respectively and changes in BAC and driving ability were analyzed. Results: Average BAC and the percentage of drivers showing impaired driving ability in the groups increased after each intake of 100 ml alcohol. BAC in Group≤60 kg was more susceptible to alcohol than that in Group>60 kg. When each drank, alcohol had greater influence on drivers who had comparatively shorter driving experience. Conclusion: Volume of consumed alcohol, BAC and driving ability have direct associations among one another and are all under the influence of various factors including individual conditions. To set an appropriate legal BAC limit for safe driving should take an overall consideration of all factors.
文摘The liver, as the central metabolic organ, plays an important role in metabolism of carbohydrates, lipids and proteins. In the environment, there are many hepatotoxic xenobiotics. CCl4 is a free radical toxic for organelles of hepatocytes. The presented work was studying the character of ultrastructural changes in CCl4-intoxicated hepatocytes as well as the tissue after treatment by grape seed extract (GSE), α-tocopherol (α-T). As a result of cell bioremediation effect and reactions against corruptive factors, the liver has a high regeneration ability.
文摘To identify early predictive markers of poor outcomes in patients with acute liver injury from wild mushroom intoxication.METHODSThis observational, retrospective record review involved adults aged ≥ 18 years admitted to emergency department with mushroom intoxication from January 2005 to December 2015. The diagnosis of mushroom intoxication was based on the following: (1) a positive history of recent wild mushroom intake (either raw or cooked); (2) the onset of gastrointestinal symptoms, such as watery diarrhea, vomiting, and/or abdominal pain, after ingestion; and (3) the exclusion of other possible causes of acute liver injury. Acute liver injury was defined by a > 5-fold elevation of liver enzymes or moderate coagulopathy [international normalized ratio (INR) > 2.0]. Clinical and laboratory findings were compared in survivors and non-survivors.RESULTSOf 93 patients with mushroom intoxication, 23, 11 men (47.8%) and 12 women (52.2%), of median age 61 years, developed acute liver injury. The overall in-hospital mortality rate was 43.5% (10/23). Among the laboratory variables, mean serum alkaline phosphatase (73.38 ± 10.89 mg/dL vs 180.40 ± 65.39 mg/dL, P < 0.01), total bilirubin (2.312 ± 1.16 mg/dL vs 7.16 ± 2.94 mg/dL, P < 0.01) concentrations and indirect/direct bilirubin (2.45 ± 1.39 mg/dL vs 0.99 ± 0.45 mg/dL, P < 0.01) ratio as well as prothrombin time (1.88 ± 0.83 mg/dL vs 10.43 ± 4.81 mg/dL, P < 0.01), and activated partial thromboplastin time (aPTT; 32.48 ± 7.64 s vs 72.58 ± 41.29 s, P = 0.01), were significantly higher in non-survivors than in survivors. Logistic regression analysis showed that total bilirubin concentration (OR = 3.58, 95%CI: 1.25-10.22), indirect/direct bilirubin ratio (OR = 0.14, 95%CI: 0.02-0.94) and aPTT (OR = 1.30, 95%CI: 1.04-1.63) were significantly associated with mortality. All patients with total bilirubin > 5 mg/dL or aPTT > 50 s on day 3 died.CONCLUSIONMonitoring of bilirubin concentrations and aPTT may help in predicting clinical outcomes in patients with acute liver injury from wild mushroom intoxication.
文摘Objective:To assess the toxicity of the pufferfish Takifugu oblongus,from Chennai coast,Tamil Nadu,India and to detect the presence of Tetrodotoxin(TTX).Methods:The toxicity was evaluated by mouse bioassay using Swiss Albino mice which were expressed in mouse units(MU).Gross anatomical features were observed which is followed by histopathology of the dead mice tissues to establish the toxicity.Instrumental analysis for the presence of tetrodotoxin was also performed through GC-MS and HPLC.Results:The toxicity of ovary was the maximum with 163 MU/g and lowest toxicity was observed in skin with 75.88 MU/g.Histopathological analyses of the dead mice showed various cellular degenerations and inflammations.The amount of Tetrodotoxin detected through GC-MS and HPLC was more reliable and sensitive than the customary mouse bioassay as instrumental analyses were able to detect even nanograms of the toxin.Conclusions:The present study evidently proved that Takifugu oblongus is highly toxic and consumption of the same can pose serious threat for health and possible lethality to humans.

In order to evaluate the epidemic status of paraquat harm to human health in China, 24 h hotline information about paraquat intoxication consultation from January Ist, 2002 to December 31st, 2011 was collected by experienced practitioners in the Poison Control Center (National Poison Control Center, NPCC)
文摘Dear editor, Following its entrance into the human body through inhalation, carbon monoxide (CO) forms carboxyhemoglobin (COHb) by binding to hemoglobin (Hb) within the blood. Massive ischemic tissue necrosis occurs in 0.5%-1% of cases with CO poisoning. The affinity of CO to Hb is 200-250 times more when compared to the affinity of oxygen. As a result of CO binding to Hb, oxygen delivery to the tissues is reduced, and tissue hypoxia develops. This affects mostly the brain and heart, which are the organs with the highest demand for oxygen.

文摘Cadmium (Cd), one of the most dangerous heavy metals, has a very similar ionic radius to calcium (Ca). The interference of cadmium in calcium homeostasis may play an important role in cadmium toxicity. Recent reports indicate that calmodulin (CaM) inhibitors such as trifluoperazine and chlorpromazine (CPZ) could protect rodents against cadmium toxicity. It was also reported that pretreatment of mice with zinc (Zn) could reduce the adverse effects induced by cadmium. The aim of this study is to determine whether Cd changes the balance of other essential metals such as Zn and copper (Cu) in rat tissues, and whether CPZ can reverse these changes which are induced by cadmium intoxication. Adult male Sprague Dawley (SD) rats were injected intraperitoneally (ip) with cadmium chloride (CdCl 2) (0.2, 0.4, 0.8 mg Cd/kg body weight) alone and 0.4mg Cd/kg in association with CPZ (5 mg/kg) daily for a week. The control animals were injected with normal saline only. The results showed that the cadmium content in the liver, kidney and testis increased significantly with a dose response relationship. Cadmium treatment markedly increased the Zn and Ca content in some of the tissues. Hepatic and renal metallothionein (MT) increased significantly after cadmium intoxication. CPZ treatment, however, reduced cadmium content in liver, but not blood and kidney. CPZ seemed to decrease the content of MT in liver and significantly increase the amounts of MT in kidney. These data suggest that the intervention of cadmium with tissue essential metals may play a role in cadmium toxicity in rats, and calmodulin inhibitors to some extent can reduce the adverse effect of cadmium by decreasing the cadmium load in tissues and reversing the unbalance of essential metals.
文摘Antagonising effects of α-ketoglutarate (α-KG) could be attributed to complexing of the reactive nucleophile (CN-) to form cyanohydrin in cyanide intoxication. However, an enormous protection obtained could not be delineated on account of possible in situ binding of α-KG given intraperitoneally (i.p.) in mice to cyanide administered through the same route. The present study was designed to see the efficacy of a-KG alone or in combination with sodium nitrite (SN) and/or sodium thiosulfate (STS) in male mice exposed to cyanide administered through subcutaneous (s.c.) or inhalation route. A technique for generation of hydrogen cyanide (HCN) is also discussed. On the basis of protection index (PI), defined here as the LD50 of cyanide in protected mice/LD50 of cyanide in unprotected mice and survival time, STS + α-KG regimen was equipotent to the conventional SN + STS regimen. This is further substantiated by effect of α-KG in reducing plasma cyanide levels. The efficacy of α-KG remains undeterred irrespective of the route of cyanide intoxication, while the magnitude of protection varies.

文摘Objective:To evaluate the effect of different doses of lead acetate(1/20,1/40 and 1/60 of LD_(50))on body weight gain,blood picture,plasma prolein profile and the function of liver,kidney and thyroid gland.Methods:Male albino rats were divided into four groups,the first group represented the health control animals,while the second,third and fourth groups were ingested orally with sub lethal doses of load acetate(1/20,1/40 and 1/60)of the oral LD_(50),respectively.One dose was ingested every two days during the experimental period(14 weeks)including the adaptation time.Blood was collected and used for all analysis.Results:The results showed that,the ingestion of Pb^(2+)induced significant stimulation in glutamic-pyruvic transaminase(ALT)and glutamic-oxalacetic transaminease(AST)activity.Also,total soluble protein and albumin contents of plasma were significantly decreased,while the content of globulin was changed by the Pb^(2+)treatments.The cholinesteiase activity was inhibited,but the activities of alkaline and acid phosphates and lactate dehydrogenase were stimulated,while plasma glucose level was elevated as a result of lead acetate intoxication.In case of blood picture,Pb^(2+)ingestion reduced the contents of hemoglobin and RBCs count of intoxicated rat's blood and the plasma levels of T3,T4 and blood WBCs count were decreased.Conclusions:It can be concluded that lead acetate has harmful effect on experimental male albino rats.Therefore,the present work advises people to prevent exposure to the lead compound to avoid injurious hazard risk.
文摘To investigate the changes of hemodynamic and laboratory parameters during the course of acute liver failure following acetaminophen overdose.METHODSEight pigs underwent a midline laparotomy following jejunal catheter placement for further acetaminophen intoxication and positioning of a portal vein Doppler flow-probe. Acute liver failure was realized by intrajejunal acetaminophen administration in six animals, two animals were sham operated. All animals were invasively monitored and received standardized intensive care support throughout the study. Portal blood flow, hemodynamic and ventilation parameters were continuously recorded. Laboratory parameters were analysed every eight hours. Liver biopsies were sampled every 24 h following intoxication and upon autopsy.RESULTSAcute liver failure (ALF) occurred after 28 ± 5 h resulted in multiple organ failure and death despite maximal support after further 21 ± 1 h (study end). Portal blood flow (baseline 1100 ± 156 mL/min) increased to a maximum flow of 1873 ± 175 mL/min at manifestation of ALF, which was significantly elevated (P < 0.01). Immediately after peaking, portal flow declined rapidly to 283 ± 135 mL/min at study end. Thrombocyte values (baseline 307 × 10<sup>3</sup>/µL ± 34 × 10<sup>3</sup>/µL) of intoxicated animals declined slowly to values of 145 × 10<sup>3</sup>/µL ± 46 × 10<sup>3</sup>/µL when liver failure occurred. Subsequent appearance of severe thrombocytopenia in liver failure resulted in values of 11 × 10<sup>3</sup>/µL ± 3 × 10<sup>3</sup>/µL preceding fatality within few hours which was significant (P > 0.01).CONCLUSIONDeclining portal blood flow and subsequent severe thrombocytopenia after acetaminophen intoxication precede fatality in a porcine acute liver failure model.
文摘<strong>Background: </strong>The main causes of mortality in patients with burn injury are the development of systemic inflammatory process, multiple organ failure and septic complications. <strong>The aim of the research:</strong> Improvement of diagnostic and therapeutic approaches to the detection and elimination of endogenous intoxication in patients with burn injury. <strong>Materials and methods:</strong> The main study group consisted of 19 patients and the comparison group—of 10 patients with burn injury. 92 blood serum (BS) samples of the patients of the main group were tested, using the method of fluorescence spectroscopy (MFS). The advanced therapeutic tactics were proposed for the patients of both groups. The control group consisted of 40 healthy individuals (donors). BS of these patients was also tested using MFS. <strong>Results: </strong>Patients with burn injury have endogenous intoxication in their blood. The effective concentration of albumin is reduced in patients with burn injury due to the blockage of albumin binding centers by bacterial metabolism products. Fluorescence spectra (FS) of BS in patients with burn trauma and donors were obtained and investigated. Based on MFS results, an improved treatment regimen using infusion of albumin solution was proposed. <strong>Conclusions:</strong> An improved technique for the management of patients with burn injury is based on the use of MFS for the diagnostic evaluation of endogenous intoxication in them. The idea of pathological changes in albumin molecules in patients with burn injury is pathogenetically substantiated by the successful use of infusion of albumin solution in these patients on the basis of the MFS.
文摘Pulmonary injury after acute H<sub>2</sub>S inhalation was studied with bronchoalveolar lavage(BAL),ultracentrifuge,and optical and electron microscopy.The changes of the activities oflactate dehydrogenase,alkaline and acid phosphatase,and angiotension converting enzymes inBAL fluid were used as the indicator of cellular damages,those of leucocytic count and the indi-cator of inflammatory response,and those of the concentration of protein and Evans blue as theindicator of vascular permeability.In addition the effects of H<sub>2</sub>S on lipid peroxidation,naturalantioxidative system and energy substances and the changes of phospholipid concentration inBAL fluid were also observed.The results were as follows:1.Inhalation of H<sub>2</sub>S exerted a severe cytotoxic effect on the lung tissues resulting in dam-ages on various types of cells and a severe edematogenic effect on lung parenchyma.2.The development of pulmonary edema in H<sub>2</sub>S intoxication resulted from a combination ofdifferent pathogenic factors.3.The biochemical changes and their recovery occurred earlier than the pathologicalchanges and their recovery.The efficacy of 6 categories of drugs including 25 medicaments against H<sub>2</sub>S intoxication wasevaluated in mice,and 10 drugs were found to be prophylactically effective.The effects of vari-ous methemoglobin-forming agents and some other drugs were also studied in their treatment ofH<sub>2</sub>S intoxication in rabbits and dogs.It was concluded that methemoglobin-forming agentscould be used as specific antidotes but could not provent or alleviate the lung damages due toH<sub>2</sub>S inhalation unless they were administered in association with dexamethasone,vitamin E oranisodamine.A scheme of the medical treatment for H<sub>2</sub>S intoxication was presented.
