The measurement of the plasma activities of glutamic-oxaloacetic and glutamic-pyruvic transaminases, aldolase, cholinesterase, and isocitric, lactic, and phosphogluconic dehydrogenases in random samples of blood was found to be of no value in the differential diagnosis of hepatitis, obstructive jaundice, hepatic cirrhosis, and neoplastic conditions involving the liver. Serial determinations of ...

Male Sprague-Dawley rats were daily given orally for 22 days a regimen consisting of polychlorinated biphenyls (PCBs), 1 mg/day; polychlorinated quaterphenyls (PCQs), 1 mg/day; polychlorinated dibenzofurans (PCDFs), 10 micrograms/day; or a mixture of PCBs, PCQs and PCDFs (Mix-1, 1 mg + 1 mg + 10 micrograms/day). Female Cynomolgus monkeys were daily administered PCBs (5 mg), PCQs (5 mg) or a mix...

A significant decrease of hepatic high-Km glucose- phosphorylating enzyme glucokinase (ATP- D- glucose 6- phosphotransferase, EC 2.7. 1.2, GK) and low-Km hexokinases (EC 2.7. 1.1. HK) activities were noticed in liver treated with 2, 2'- dichlorodiethyl sulfide (sulfur mustard, HD) when injectedinteraperitoneally to male rats in 114 LD50. This decrease occurred 1.5 to 5.5 hours after the in...

The present studies were designed to clarify the contribution of the liver to the development of hyperglycemia in Wistar fatty rats. The hepatic activities of insulin-inducible enzymes involved in glycolysis (glucokinase; GK and pyruvate kinase) and lipogenesis (glucose-6-phosphate dehydrogenase), were higher in fatty rats than in lean rats at 4 and 8 weeks of age because of the higher insulin ...

Effects of dietary carbohydrates on triglyceride production and hepatic lipogenic enzyme activities were examined in Wistar fatty rats, an animal model of noninsulin dependent diabetes mellitus, fed fructose or glucose and were compared with those of Wistar lean rats. Carbohydrates were supplied in 10% drinking solutions for 21 days. As compared with lean rats, Wistar fatty rats were characteri...

We investigated the effect of curcumin on insulin resistance and glucose homeostasis in male C57BL/KsJ-db/db mice and their age-matched lean non-diabetic db/+ mice. Both db/+ and db/db mice were fed with or without curcumin (0.02%, wt/wt) for 6 wks. Curcumin significantly lowered blood glucose and HbA 1c levels, and it suppressed body weight loss in db/db mice. Curcumin improved homeostasis mod...
