The degree of metabolic rehabilitation of the bronchopulmonary system was evaluated in non-specific pulmonary diseases, like pneumonia or chronic obstructive bronchitis, by using the data of biochemical testing of the exhaled-air vapor condensate. Nine parameters were investigated, i.e. enzymes alanine aminotransferase (ALT), aspartate aminotransferase (AST), lactate dehydrogenase, alkaline phosphatase (AP), gamma-glutamate amino-transpeptidase (GGT) as well as parameters of protein metabolism--common protein, seromucoid (SC), C-reactive protein and urea. AST, ALT, AP, GGT, SC and urea were acknowledged as the most informative parameters. The results are indicative of that the recovery of metabolic processes in the bronchopulmonary system was not completed.

BACKGROUND/AIM:: Cirrhosis in chronic hepatitis C is a major cause of mortality. The components of reported diagnostic indices of cirrhosis based on biochemical markers may be modified by therapies for hepatic inflammation. We aimed to construct index of cirrhosis in patients treated for chronic active hepatitis. METHODS:: Using sera of consecutive 140 patients with chronic hepatitis C, routine blood tests including fibrosis markers, type IV collagen and procollagen type III peptide (PIIIP), were performed. Diagnosis of cirrhosis was determined by biopsy. Using multivariate analyses, diagnostic indices of cirrhosis were constructed. RESULTS:: Fifty-eight patients were diagnosed to have cirrhosis. Platelet count, prothrombin time, and albumin were lower, and type IV collagen and PIIIP were higher in patients with cirrhosis (p<0.05). There was no difference in aspartate and alanine aminotransferases (AST, ALT) and gamma-glutamyl-transpeptidase (GGT) (p>0.3). Our diagnostic indices I (prothrombin time and platelet count) and II (prothrombin time and type IV collagen) of cirrhosis showed the area under the ROC curves (AUC) of 0.77 and 0.81, respectively. The index II was relatively superior to the index I. CONCLUSIONS:: Using combination of type IV collagen and prothrombin time, efficient diagnosis of cirrhosis can be performed in patients with chronic active hepatitis C.

To determine whether the current liver screening program for fatty liver has sufficient scientific evidence to justify its continued implementation. The liver screening program to detect fatty liver was performed on 411 Japanese workers utilizing serum aspartate aminotransferase (ALT), alanine aminotransferase (AST), and gammaglutamyl transpeptidase (gamma-GTP). Based on the preceding studies, subjects with viral and alcohol hepatitis were excluded from the evaluation. The diagnosis of fatty liver was based on ultrasound findings. The program was evaluated by efficacy and effectiveness; efficacy was measured according to the receiver operating characteristic (ROC) curves in comparison with the Body Mass Index (BMI). Effectiveness, based on the efficacy determinations, was assessed by means of the positive predictive value (PPV) test performance, the disease characteristics, and the program price. The diagnostic performances of ALT and BMI were nearly acceptable but far from excellent. The areas under the curves of the two indices were 0.69 and 0.63, respectively and these were statistically equivalent. The PPV ranged from 15 to 28% where the prevalence of fatty liver was 12.3%. The price of the program was estimated at US 4 dollars per person based on the medical reimbursement fee rate. The efficacy of the liver screening program was found to be insufficient and BMI monitoring may provide a more suitable and inexpensive alternative. Furthermore, the effectiveness of the program is open to question, considering the generally benign prognosis of the disease in the absence of any accompanying morbid conditions and the high price of the program.

The chemopreventive effect of ethanol extract of Indigofera aspalathoides (EIA) on N-nitrosodiethylamine (DEN, 200 mg/kg)-induced experimental liver tumor was investigated in male Wistar rats. Oral administration of ethanol extract of Indigofera aspalathoides (250 mg/kg) effectively suppressed liver tumor induced with DEN as revealed by decrease in the levels of extend of serum glutamate pyruvate transaminase (SGPT), serum glutamate oxaloacetate transaminase (SGOT), alkaline phosphatase (ALP), total bilirubin, gamma glutamate transpeptidase (GGTP), lipid peroxidase (LPO), glutathione peroxidase (Gpx) and glutathione S-transferase (GST) with a concomitant increase in enzymatic antioxidant (superoxide dismutase and catalase) levels when compared to those in liver tumor bearing rats. The histopathological changes of liver sample were compared with respective control. Our results show a significant chemopreventive effect of EIA against DEN induced liver tumor.

The chemopreventive and cytotoxic effect of ethanol extract of Bauhinia variegata (EBV) was evaluated in N-nitrosodiethylamine (DEN, 200 mg/kg) induced experimental liver tumor in rats and human cancer cell lines. Oral administration of ethanol extract of Bauhinia variegata (250 mg/kg) effectively suppressed liver tumor induced by DEN as revealed by decrease in DEN induced elevated levels of serum glutamate pyruvate transaminase (SGPT), serum glutamate oxaloacetate transaminase (SGOT), alkaline phosphatase (ALP), total bilirubin, gamma glutamate transpeptidase (GGTP), lipid peroxidase (LPO), glutathione peroxidase (GPx) and glutathione S-transferase (GST). The extract produced an increase in enzymatic antioxidant (superoxide dismutase and catalase) levels and total proteins when compared to those in liver tumor bearing rats. The histopathological changes of liver samples were compared with respective controls. EBV was found to be cytotoxic against human epithelial larynx cancer (HEp2) and human breast cancer (HBL-100) cells. These results show a significant chemopreventive and cytotoxic effect of ethanol extract of Bauhinia variegata against DEN induced liver tumor and human cancer cell lines.

We describe the case of a patient with chronic hepatitis C (CHC) who showed a progressive increase in aminotransferase level, reaching values of aspartate aminotransferase 1723 UI/L, alanine aminotransferase 1519 UI/L and gamma-glutamyl-transpeptidase 296 with a bilirubin level of 6 mg/dL and direct bilirubin level of 4.6 mg/dL. One year previously, the patient had been diagnosed with CHC, genotype 1, and had an initial hepatitis C virus RNA load of 249,000 UI/mL. All the specific blood tests performed were negative except for antisoluble liver antigen (anti-SLA) antibodies, which were positive in two different determinations. A diagnosis of overlap syndrome CHC and autoimmune hepatitis was made. Steroid and azathioprine treatment was started with good response. The relationship between CHC and anti-SLA is not well characterized but has been described in these patients. We found no prior reports in the literature of CHC associated with positive anti-SLA in a patient with persistent acute hepatitis.

The alcoholic extract of stem of Indigofera aspalathoides was evaluated for its antihepatotoxic activity against CCl(4)-induced hepatic damage in rats. The activity was evaluated by using biochemical parameters, such as serum glutamate pyruvate transaminase (SGPT), serum glutamate oxaloacetate transaminase (SGOT), alkaline phosphatase (ALP), total bilirubin and gama glutamate transpeptidase (GGTP). The histopathological changes of liver sample were compared with respective control. The extract showed remarkable hepatoprotective effect.

Hepatoprotective activity of ethanolic extract of flowers of Vitex trifolia (Verbenaceae) was studied against CCl4 induced hepatic injury in albino rats. The plant extract (EVT) at the dose of 200 mg/kg, p.o. showed a remarkable hepatoprotective activity. CCl4 induced a significant rise in serum glutamate pyruvate transaminase (SGPT), serum glutamate oxaloacetate transaminase (SGOT), alkaline phosphatase (ALP), total bilirubin and gamma glutamate transpeptidase (GGTP). Treatment of rats with EVT significantly (P<0.001) altered serum biomarker enzyme levels to near normal against CCl4 treated rats. The activity of the extract was comparable to the standard drug, silymarin (100 mg/kg, p.o.). Histopathological observations also revealed that treatment with EVT protected the animals from CCl4 induced liver damage. The results indicate that the flowers of V. trifolia possess hepatoprotective activity on CCl4 induced hepatic injury in rats.

OBJECTIVE. Severe (PiZZ) alpha(1)-antitrypsin (AAT) deficiency is a risk factor for liver disease, i.e. juvenile cirrhosis in infancy, and cirrhosis and hepatoma in adulthood. Little is known about the risk of liver disease in individuals with moderate (PiSZ) AAT deficiency. To investigate the natural course of AAT deficiency, a cohort of PiZZ and PiSZ individuals identified by the Swedish National neonatal screening programme in 1972-74 is followed regularly. The aim of this study was to compare liver function in this cohort with healthy control subjects aged 30 years. MATERIAL AND METHODS. Blood samples were obtained from 89 PiZZ, 40 PiSZ, and 84 control subjects (PiMM), and plasma levels of aspartate aminotransferase (AST), alanine aminotransferase (ALT), and gamma-glutamyl (GT) transpeptidase were analysed. RESULTS. The mean values of all liver enzymes were within the normal range in all Pi subgroups. However, the mean AST was higher in the PiZZ and PiSZ subgroups than in the PiMM subgroup (p < 0.001), and the mean ALT was higher in the PiZZ individuals than in the controls (p < 0.05), while GT did not differ significantly among the Pi subgroups. The PiZZ women taking oral contraceptives had higher mean AST and ALT (p < 0.01) and GT (p < 0.05) than the control women taking oral contraceptives. CONCLUSIONS. At the age of 30 years, PiZZ and PiSZ individuals have normal plasma levels of the transaminases AST and ALT, although they are significantly higher than those in healthy control subjects. Use of oral contraceptives seems to influence liver enzymes in PiZZ women.

The aim of the present study was to assess the physiological response of male zebrafish Danio rerio to the fungicide tebuconazole and recovery in fungicide-free water. Acute toxicity tests were carried out and the median lethal concentration (LC(50)) from 24 to 96 h was calculated. The fish were exposed to a sublethal fungicide concentration of 230 microg/L for 7 or 14 days and allowed to recover for 7 or 14 more days, respectively. Whole-body levels of vitellogenins, triglycerides, cholesterol, glucose, lactate and proteins as well as the activities gamma-glutamil transpeptidase (gamma-GT), alanin aminotransferase (AlAT), alkaline phosphatase (AP) and lactate dehydrogenase (LDH) were assayed; corpulence factor (k) was also calculated. Fish exhibited significant increase of vitellogenins (Vtg), which continued to increase after 14 days of recovery. Levels of glucose, lactate, cholesterol and triglycerides increased after 7 and 14 days of exposure. Finally, cholesterol and glucose recovered after 14 days of recovery whereas triglycerides and lactate continued to be elevated. Proteins and k remained unaltered the entire experiments. AAT, AlAT and AP enhanced during exposure and did not recover at the end (except AlAT). A longer recovery period should be necessary to re-establish fish physiology. These results alert about the multiple disruptive physiological actions that tebuconazole may have on fish.
