Introduction/Aim. By analyzing activity of some of the enzymes normally present in the saliva and the level of malondialdehyde in gingivitis, it is possible to estimate the functional condition of parodontium, and the examined parameters can be considered as biochemical markers of its functional condition. The aim of this paper was to examine activity of alanine aminotransferase, aspartate aminotransferase, gamma glutamyl transferase, lactate dehydrogenase and the level of malondialdehyde in the saliva of children affected with gingivitis, as well as the values of the mentioned parameters in relation to the level of the inflammation of gingiva. Methods. The research included 120 children at the age of 12.2 with permanent dentition. L?e and Silness gingival index was used to estimate the condition of gingiva, based on which the children were classified into four groups: the children with healthy gingiva (the control groups), the children with mild, moderate and severe inflammation of gingiva (the study group). Enzymes of the saliva were determined by the use of original tests and measured by the autoanalyser (Bio Systems A25, Spain). A modified method with tiobarbituric acid was used to determine malondialdehyde in nonstimulated mixed saliva. Results. The results of the examined enzyme activity and the level of malondialdehyde in the saliva of the study groups showed statistically considerably higher values for the level of malondialdehyde (p < 0.001), for the activity of aspartate aminotransferase and gamma glutamyl transferase (p < 0.01), as well as for alanine aminotransferase (p < 0.05) in comparison with the control group, whereas the activity of lactate dehydrogenase did not show a statistically significant increase. In relation to the level of the inflammation of gingiva, the results of the examination of the enzyme activity in the study groups showed statistically significantly higher values in the group with severe inflammation in comparison with those with mild, as well as the moderate inflammatory, except for the gamma glutamyl transferase, and in the group with moderate inflammation compared to that with the mild one, except for alanine aminotransferase. The results of the examination of the level of malondialdehyde in the saliva of the study groups did not show a statistically significantly increase in relation to the level of the inflammation of gingiva. Conclusion. There is a higher level of alanine aminotransferase, aspartate aminotransferase, gamma glutamyl transferase and lactate dehydrogenase enzyme activity together with the higher level of malondialdehyde in the saliva of children with gingivitis in comparison with the activity of the same enzymes and the level of malondialdehyde in the saliva of children without gingivitis. The activity of the examined enzymes in the saliva of children with gingivitis increases in relation to the intensity of the pathological process, whereas the level of malondialdehyde shows no significant difference in relation to the level of the inflammation of gingiva.

Introduction: Liver disease and diabetes often co-occur and have shared risk factors. We undertook this study to investigate which liver enzyme (alanine aminotransferase (ALT), aspartate aminotransferase (AST), or gamma-glutamyl transferase (GGT)) would be most strongly associated with incident diabetes in a large, community-based population. Hypothesis: We hypothesized that ALT, AST, and GGT would be independently associated with diabetes and that ALT would be most strongly associated with diabetes due to its liver specificity. Methods: We conducted a prospective analysis of 9,524 participants in the ARIC Study without diagnosed diabetes or a history of high alcohol consumption (>14 [women] and >21 [men] drinks/week). Enzymes were measured from stored plasma samples. We examined the association of sex-specific quartiles of liver enzymes with incident diagnosed diabetes using Cox proportional hazards models adjusted for demographic, lifestyle, and behavioral risk factors. Restricted cubic spline models were fit to model the continuous associations. Results: Median ALT, AST, and GGT were 13, 18, and 22 U/L, respectively. During a median follow-up of 11 years, there were 1,905 self-reported cases of diabetes. All three liver enzymes were significantly associated with diabetes, even after adjustment for all covariates (HRs (95% CIs): ALT, 1.63 (1.44, 1.85); AST, 1.23 (1.09, 1.40); GGT, 1.99 (1.71, 2.30) comparing Q4 versus Q1). The restricted cubic spline models show similar patterns (Figure). After simultaneously adjustment for the other liver enzymes, only ALT and GGT remained significantly associated with diabetes. In analyses further restricted to participants who reported never consuming alcohol only GGT remained significant. Conclusion: In this community-based population, GGT was more strongly associated with diabetes risk than ALT and AST. Although ALT and AST are considered to be more specific markers of liver disease, higher levels of GGT may be a more important risk factor for diabetes.

The medical bibliography is deficient in research involving structural and laboratory abnormalities of the liver in asymptomatic and oligosymptomatic male alcoholics. The present study describes the alterations in tests that evaluate liver aggression, lesion and dysfunction, also correlating these with the changes in the consistency and sensitivity of the liver in aged and non-aged alcoholics. Cross-sectional study involving 100 alcoholic men, 50 aged and 50 non-aged. Of the aged and non-aged, respectively, the liver was palpable in 68% and 80%, the spleen was percutable in 72% and 74% and palpable in 12% and 22%, non-painful soft hepatomegaly was observed in 14% and 8%, painful hepatomegaly in 0% and 2%, firm hepatomegaly (painful and non-painful) in 54% and 70%, hepatomegaly and splenomegaly (percutable and palpable spleen) in 84% and 84%, and portal hypertension in 10 % and 14%. Elevated levels of aspartate aminotransferase were observed in 66% and 84%, alanine aminotransferase in 24% and 60%, gamma glutamyl transferase in 46% and 82% and alkaline phosphatase in 0% and 16% of the aged and non-aged, respectively. Elevation of aspartate aminotransferase greater than twice the reference value and the ratio aspartate aminotransferase to alanine aminotransferase greater than 2 were observed in 18% and 42% and 18% and 10% of the aged and non-aged, respectively. Hypoalbuminemia and hyperbilirubinemia were observed in 70% and 24% of the aged and 40% and 44% of the non-aged, respectively. The clinical and laboratory alterations observed are compatible with acute liver disease in 18% and 42%; chronic liver disease in 54% and 70%; portal hypertension in 10% and 14% of aged and non-aged patients, respectively.

Abstract Background Hepatocellular carcinoma is the most frequent primary malignancy of liver and accounts for as many as one million deaths worldwide in a year. Objectives The aim of the present study was to evaluate the anti-cancerous efficiency of Bergenia ciliata rhizome against diethylnitrosoamine induced hepatocarcinogenesis in Balb C mice. Methods One percent diethylnitrosoamine was prepared by using 99 ml of normal saline NaCl (0.9 percent) solution to which was added 1 ml of concentrated diethylnitrosoamine (DEN) solution (0.01 μg/μl). Extract of Bergenia ciliata was prepared by maceration technique. Mice were classified into four groups as follows: Group 1 a control group (N=7) received saline solution (3.5 μl/mg), group 2 (N=14) received diethylnitrosoamine (3.5 μl/mg) intraperitoneally once in a week for eight consecutive weeks, group 3 (N=7) received plant extract (150 mg/kg (Body weight)) once in a week, while group 4 (N=7) was given combination of diethylnitrosoamine (3.5 μl/mg) and plant extract (150 mg/kg (Body weight)). After eight weeks of DEN induction group 2 mice were divided into two subgroups containing seven mice each, subgroup 1 was sacrificed while subgroup 2 was treated with plant extract (150 mg/kg (Body weight)) once in a week for eight consecutive weeks. Results The model of DEN injected hepatocellular carcinomic (HCC) mice elicited significant decline in levels of albumin with concomitant significant elevations in tumor markers aspartate aminotransferase, alanine aminotransferase (ALT), lactate dehydrogenase (LDH), alpha feto protein (AFP), gamma glutamyl transferase (Y-GT), 5 nucleotidase (5NT), glucose-6-phosphate dehydrogenase (G6PDH) and bilirubin. The intraperitoneal administration of B. ciliata as a protective agent, produced significant increase in albumin levels with significant decrease in the levels of tumor markers aspartate aminotransferase (AST), alanine aminotransferase (ALT), lactate dehydrogenase (LDH), alpha feto protein (AFP), gamma glutamyl transferase (Y-GT), 5 nucleotidase (5NT), glucose-6-phosphate dehydrogenase (G6PDH) and bilirubin. Conclusion Bergenia ciliata has potent antioxidant activity, radical scavenging capacity and anticancerous properties. Bergenia ciliata extracts may provide a basis for development of anti-cancerous drug.

Relevance. Assessment of liver damage and functional state is one of the leading tasks of clinical and laboratory diagnostics. Traditionally used methods for determining the activity of a number of indicator enzymes in blood with relative organ-specificity, such as aspartate aminotransferase, alanine aminotransferase, lactate dehydrogenase, sorbitol dehydrogenase, alkaline phosphatase, and -glutamyl transferase, have low specificity for liver diseases. In this regard, the determination of the optimal marker of acute liver injury is an urgent problem. Aim. The purpose of the study is to determine the dynamics of changes in liver damage markers in rats at different periods of reperfusion after 20 minutes of ischemia in order to select the indicators that most informatively characterize the state of test-animals under conditions of correction of ischemia-reperfusion syndrome. Materials and methods: the study was performed on 120 white nonlinear male rats weighing 200250 grams. The animals were divided into 8 groups of 15 test-animals; all of them were simulated liver ischemia by clamping the analog of the hepatoduodenal ligament with a vascular clamp for 20 minutes. Then, blood was taken from different groups of rats at different reperfusion times 5, 15, 30, 60, 120, 180 minutes, 8 hours and a day. In the blood plasma of laboratory animals, the activity of alanine aminotransferase (ALT), aspartate aminotransferase (AST), lactate dehydrogenase (LDH), glutathione transferase (GST), and lactate concentration were determined. Results: the results obtained allowed us to characterize two main peaks of indicators: a 5-minute period after restoration of blood flow the maximum activity of glutathione transferase and lactate concentration, increased by 3.94.7 times; 60180 minutes of reperfusion is the peak of aminotransferase activity, a significant increase in the activity of which begins 60 minutes after the restoration of blood flow and reaches its maximum by the 3rd hour of reperfusion, and LDH, the peak of which is recorded already by the 60th minute of revascularization. At the same time, after 8 hours of reperfusion, an obvious tendency for a decrease in all studied parameters was determined, which ends a day after modeling ischemia with a decrease to the level of control values. Conclusion: the assessment of organ damage in the ischemic period and the anti-ischemic effect of metabolic drugs can be carried out with the determination of an increase in lactate concentration and glutathione transferase activity almost immediately after restoration of blood flow. The development of injuries during the reperfusion period is more expedient to assess by determining AST, ALT and LDH after a 3-hour period of blood flow restoration, at which time the maximum values of markers are recorded under the condition of 20-minute total liver ischemia.

Objectives: Our goal was to contribute to the production of reference values ​​of plasma or serum biochemical markers by determining the reference values ​​of gamma-glutamyltransferase (GGT), aspartate aminotransferase (ASAT) and alanine aminotransferase (ALAT) in young Congolese presumed to be healthy. Methods: 250 young Congolese presumed to be healthy (125 boys and 125 girls) aged 15 to 25 participated in the study. They were selected according to anamnestic and clinico-biological criteria. Samples were taken on a tube containing EDTA and the resulting plasma was stored at -20 ° C. The KENZA MAX spectrophotometer was used to analyze GGT, ASAT and ALAT. The median and the 2.5-97.5 percentiles were used to set the reference limits for each enzyme. The benchmarks determined were compared with those reported by other Africans, Europeans, Indians and Americans. Results: The established reference values ​​were: GGT 12.15-61.85 IU/L for boys and 7-51.95 IU / l for girls (p˂0.0001); ASAT 21.60-94.85 IU/L for boys and 17-84.85 IU/L for girls (p = 0.0003); ALAT 8.30-74.40 IU/L for boys and 8-53.85 IU/L for girls (p˂0.0001). In addition, the comparison between our values ​​and those of other populations showed significant differences. Conclusion: Our results underline the importance of establishing reference values ​​for plasma enzymes specific to the Congolese population. The use of the values ​​established in the ’other populations could induce errors of judgment by excess or by default. Key words: Gamma-glutamyltransferase, Aspartate aminotransferase, Alanine aminotransferase, Reference values, Congo.
