Mercuric chloride (HgCl2) administered at a dose of 1mg/kg body wt/day for 5 days decreased hepatic lactate dehydrogenase (LDH) activity (63%) and increased isocitrate dehydrogenase (ICDH) activity (127%). After withdrawal of HgCl2 treatment for 10 days, the LDH and glutamate pyruvate transaminase (GPT) activities showed 56% and 40% decrease, respectively, while alkaline phosphatase (AkP) activity increased 4.12 fold. The ICDH activity got normalized. Glutamate oxaloacetate transaminase (GDT) was not affected at all. The hepatic LDH, ICDH and GPT activities decreased 58%, 72% and 82%, respectively, five days after partial hepatectomy (PH), while AkP activity increased 90%. At the end of 15 days after PH, the hepatic ICDH activity increased 4.27 fold, while GPT and GOT activities decreased 67% and 91%, respectively. The hepatic ICDH activity of PH-rabbit increased 53%, after 5 days of HgCl2 treatment post-PH, while GPT and AkP activities decreased 89% and 97%, respectively, during this period. The ICDH activity increased 416%, 10 days after the last dose, while all other enzymes showed normal values. The total body growth rate and relative liver weight decreased under all experimental conditions.

Gossypol was administered in Goya olive oil to low protein-fed (LP, protein-malnourished) and normal protein-fed (NP, control) adult male albino Wistar rats for 4 and 8 weeks at 20 mg/kg body weight/rat/day. At the end of the experiment, the rats were killed and blood was drawn from the rats by cardiac puncture and subjected to hematological and biochemical analyses. The data obtained were analyzed by two-way analysis of variance (ANOVA). The interaction of the treatments produced significant effects on serum levels of sodium, potassium, cholesterol, triglyceride, urea, glutamate oxalate transaminase, glutamate pyruvate transaminase, amylase and blood platelet count (P < 0.001), and uric acid (P < 0.01). Significant effects were produced on serum phosphate, albumin and blood reticulocyte count (P < 0.05) but not on packed cell volume, red blood cell count, white blood cell (WBC) count and WBC differential counts, hemoglobin concentration, creatinine, creatinine phosphokinase and alkaline phosphatase (P < 0.05). The administration of gossypol reduced the level of transaminases, cholesterol and uric acid in LP and NP rats, increased the levels of triglycerides, amylase, platelet and reticulocyte count in LP rats but decreased them in NP rats. The implications of the findings are discussed.

Hepatotoxic effects of chromium have been studied on the liver function enzymes of male New Zealand white rabbits, Oryctolagus cuniculus, with and without pretreatment with phenobarbitone (PB) and promethazine (PM). The total body weight was decreased under all experimental conditions. After PB administration (5 mg/kg body wt/day for 5 days), the serum glutamate oxaloacetate transaminase (GOT), glutamate pyruvate transaminase (GPT), lactate dehydrogenase (LDH), and isocitrate dehydrogenase (ICDH) activities decreased 21%, 65%, 25%, and 37%, respectively, whereas the alkaline phosphatase (AP) activity increased 70%. After PM treatment (5 mg/kg body wt/day for 5 days) the serum GPT was inhibited 73%, whereas LDH activity was increased 37%. The hepatic GPT and AP activities decreased after PB (52% and 31%, respectively), and PM (48% and 44%, respectively) treatments, whereas the activities of LDH and ICDH increased (after PB: 817% and 109%, respectively, and after PM: 136% and 44%, respectively). Potassium dichromate, administered at a dose of 8 mg/kg body wt/day for 5 days, decreased serum GOT (44%), GPT (61%), LDH (63%), and AP (44%) activities. The hepatic GOT, GPT and AP activities were likewise decreased (86%, 51%, and 46%, respectively), whereas hepatic LDH and ICDH activities increased 667% and 193%, respectively. When administered to PB-pretreated animals, the serum GOT and AP activities were decreased (50% and 68%), whereas ICDH was increased (29%). The hepatic GOT, LDH, and ICDH activities increased 79%, 221%, and 130%, respectively. In the PM-pretreated animals, the chromium treatment inhibited the activities of serum GOT (48%), GPT (44%), and LDH (43%). The hepatic GPT, LDH, and ICDH activities increased 90%, 133%, and 52%, respectively.

The effect of human placental extract (HPE) on liver regeneration in rats was investigated. After intravenous administration of HPE to a-naphthylisothiocyanate (ANIT)-intoxicated rats, the labeling index in hepatocytes was significantly increased to a level 16.5 times higher than that of the control. A 1/500 dilution of HPE directly stimulated DNA synthesis of the hepatocytes in primary culture. HPE heated at 121 degrees C did not stimulate the labeling index in vivo or hepatocyte DNA synthesis in primary culture, suggesting that HPE contains heat-unstable but potent mitogens for hepatocytes. HPE contains hepatocyte growth factor (HGF), but the mitogenic effect of HPE cannot be explained by the effect exerted by HGF alone, since both the labeling index in vivo and hepatocellular DNA synthesis in vitro stimulated by HPE were much higher than those stimulated by HGF alone when the applied doses of HGF were set to be almost the same level between each case. When HPE was fractionated on a heparin-sepharose column, the mitogenic effect of HPE was found to be located mainly in the heparin-bound fraction. Hepatocyte DNA synthesis induced by this fraction was enhanced cooperatively by the heparin-unbound fraction, suggesting that there are some modulators in the heparin-unbound fraction which enhance the proliferative activity of the heparin-bound fraction by a synergetic mechanism. Both HPE and heated HPE completely recovered the biochemical marker activity for liver function (glutamic-pyruvic transaminase, GPT; alkaline phosphatase, ALP; lactate dehydrogenase, LAP; gamma-glutamyltransferase, gamma-GTP activities and the bilirubin concentration) almost to the control level in the serum of ANIT-intoxicated rats, indicating that HPE also contains a heat-stable fraction which repairs liver function.

Cadmium induced lipid peroxidation (LPO) and the activity of antioxidant enzymes after the administration of a single dose of CdCl2 (0.4 mg kg-1 body wt, i.p.) was studied in rat erythrocytes. Cd intoxication increased erythrocyte LPO along with a decrease in superoxide dismutase (SOD) up to three days of Cd treatment. The decrease in erythrocyte catalase (CAT) activity was marked within 9 h of Cd intoxication. After three days of Cd treatment, LPO decreased towards normal, along with an increase in erythrocyte SOC and CAT activity. Blood glutathione (GSH) decreased significantly within 24 h of Cd treatment, followed by an increase towards normal. Erythrocyte glutathione S-transferase (GST) activity increased up to 10 days of Cd intoxication, probably in an attempt to reduce Cd toxicity. Serum glutamate pyruvate transaminase (SGPT), serum alkaline phosphatase (SALP) and serum bilirubin increased up to 10 days of Cd intoxication. Blood urea increased significantly up to three days, followed by a decrease towards normal. The results show that Cd induced LPO was associated with a decrease in antioxidant enzymes and GSH in erythrocytes; as these antioxidants increase in erythrocytes with recovery from Cd intoxication, the Cd induced LPO reversed towards normal. The increase in the SGPT, SALP and serum bilirubin correlated with LPO. The results suggest that Cd intoxication induces oxidative stress and alters the antioxidant system, resulting in oxidative damage to rat erythrocytes.

Tumour markers correlate strongly with prognosis based on tumour burden and surgical resectability. If chemotherapy is extremely effective in certain stage of the disease, the sensitive marker may be of great use in monitoring disease response and drug treatment. Hence, this study was launched to evaluate the changes in tumour marker enzymes like lactate dehydrogenase (LDH), glutamate oxaloacetate transaminase (SGOT), glutamate pyruvate transaminase (SGPT), alkaline phosphatase, and acid phosphatase in before and after 3 and 6 months tamoxifen treated breast cancer patients. In addition, the changes in serum glycoproteins viz., hexose, hexosamine, and sialic acid and lysosomal enzymes such as N-acetyl-beta-D-glucosaminidase, beta-D-galactosidase, and beta-D-glucuronidase were analysed in these patients. These values were compared with their age matched healthy control subjects. At 6 months evaluation, the tamoxifen treated postmenopausal breast cancer women showed a statistically significant decreased (p < 0.001, 0.05 respectively) levels of LDH, SGOT, SGPT, alkaline and acid phosphatases than their baseline values. Similarly, the levels of hexose, hexosamine, and sialic acid and N-acetyl-beta-D-glucosaminidase, beta-D-galactosidase, and beta-D-glucuronidase were decreased significantly (p < 0.001) in tamoxifen received postmenopausal women. The result of this study suggested that tamoxifen potentially retard the metastasis of breast cancer as well as the bone demineralisation in postmenopausal breast cancer women. Thus, tamoxifen may also have its antitumour activity through its beneficial effects on tumour marker enzymes and serum proteins in breast cancer women.

In this study we examined the effects of continuous calcium channel blocker (CCB) infusion on pancreatic duct-ligated acute pancreatitis (AP) in rabbits. Thirty rabbits were used for this study. Animals in group 1 (n = 10), which served as a control group, underwent dummy operations and received 0.5 microliter/h normal saline via the internal jugular vein. Animals in group 2 (n = 10) with artificially-induced pancreatitis received the same dosage of saline in the same manner. Animals in group 3 (n = 10) with artificially-induced pancreatitis received 180 micrograms/kg/h CCB (Verapamil) via the jugular vein starting from just before pancreatic duct ligation. AP histology score, plasma amylase levels and liver function tests were measured after 48 h. Verapamil infusion did not prevent the rise in plasma amylase levels, nor did it prevent pancreatic inflammation and damage. Serum levels of serum glutamate pyruvate transaminase, serum glutamate oxalacetate transaminase and alkaline phosphatase were significantly elevated in group 2 and significant reductions were seen in the Verapamil treated animals (group 3). The findings in this study imply that a continuous 180 micrograms/kg/h dose Verapamil infusion does not ameliorate the pathogenesis of pancreatitis induced by ligation of pancreatic duct but do not rule out a dose-dependent protective effect. Meanwhile, the lowering of liver function test scores should be considered the beneficial effect of CCBs, and this should be investigated in further studies.

Extracts of Emblica officinalis (EO), Phyllanthus amarus (P. amarus) and Picrorrhiza kurroa (P. kurroa) significantly inhibited hepatocarcinogenesis induced by N-nitrosodiethylamine (NDEA) in a dose dependent manner. The anticarcinogenic activity of these extracts were evaluated by their effect on tumour incidence, levels of carcinogen metabolizing enzymes, levels of liver cancer markers and liver injury markers. Animals treated with NDEA alone showed 100% tumour incidence and significantly elevated tissue levels of drug metabolizing enzymes such as glutathione S-transferase (GST) and aniline hydroxylase (AH). Treatment of extracts significantly reduced these levels. Levels of gamma-glutamyl transpeptidase (GGT) were also found to be elevated both in serum and tissues of tumour bearing animals, while they were significantly reduced in the treated group. Similar reduction was seen in tissue levels of reduced glutathione. Serum levels of lipid peroxide (LPO), alkaline phosphatase (ALP) and glutamate pyruvate transaminase (OPT), which are markers of liver injury, were also elevated. Morphology of liver tissue and levels of marker enzymes indicated that these extracts offered protection against chemical carcinogenesis.

About 50 mg of silver leaf (metallic silver) was given daily by mouth to 30 healthy volunteers for 20 days. A statistically significant hypophospholipidemic, hypotriglyceridemic, hypocholesterolemic and hypoglycemic effect was observed. This was accompanied by a less marked fall in total lipids and significant rise in HDL-cholesterol. In addition, a decrease in plasma enzymes - alkaline phosphatase (ALP), glutamate oxaloacetate transaminase (GOT), glutamate pyruvate transaminase (GPT), creatine phosphokinase (CPK), gamma glutamyl transpeptidase (GGT) and lactate dehydrogenase (LDH) was noted. This was statistically significant for all enzymes except CPK. The safety of ingested silver foil is indicated by absence of pathology in urine and unaltered levels of protein and albumin in the plasma. These observations suggest that silver could be beneficial in conditions like diabetes mellitus, obesity and atherosclerosis.

The active fraction of Ixora coccinea flowers showed chemoprotective effects on cyclophosphamide - induced toxicity by increasing the life span of treated mice, preventing body weight loss and maintaining near normal leucocyte and haemoglobin levels compared with cyclophosphamide treated controls. Decreased serum glutamate pyruvate transaminase (SGPT) and serum alkaline phosphatase (SAKP) levels in the Ixora coccinea treated groups indicated protection against hepatic toxicity. The active fraction was identified by phytochemical methods as the triterpenoid, ursolic acid.
