The efficacy of Picroliv, a standardized iridoid glycoside fraction of Picrorhiza kurroa, was studied against the Amanita phalloides-induced biochemical changes in rat liver. A phalloides (50 mg.kg-1) caused significant increases in the activities of hepatic 5'-nucleotidase, gamma-glutamyl
Administration of aflatoxin B1 to rats (2 mg/kg intraperitoneally) caused significant increase in the activities of gamma-glutamyl transpeptidase, 5'-nucleotidase, acid phosphatase, acid ribonuclease as well as content of lipid peroxides in liver after six weeks. However, the activities of succinate
Single doses of aflatoxin B1 (2 mg/kg, i.p.) caused significant increases in the activities of tau-glutamyl transpeptidase, 5'-nucleotidase, acid phosphatase and acid ribonuclease, and decreases in the activities of succinate dehydrogenase and glucose-6-phosphatase in liver, after 8 weeks. The level
Monocrotaline, a pyrrolizidine alkaloid, caused changes in most of the biochemical parameters in rats 12 days after a single dose of 120 mg/kg. These included significantly increased activities of hepatic succinate dehydrogenase, acid ribonuclease, acid phosphatase, gammaglutamyl transpeptidase and
The hepatoprotective activity of Picroliv, a standardized iridoid glycoside fraction of Picrorhiza kurroa, has been investigated by studying the protection of biochemical and histological changes induced in livers of rats given single oral doses (7 mg/kg) of aflatoxin B1. Administration of aflatoxin
D-Galactosamine (800 mg/kg, intraperitoneally) caused significant decrease in the activities of 5'-nucleotidase, glucose-6-phosphatase and cytochrome P450 and increase in activities of gamma-glutamyl transpeptidase, succinate dehydrogenase, acid phosphatase and acid ribonuclease in liver after 24
Administration of picroliv, a standardized fraction of alcoholic extent of Picrorhiza kurroa (3-12 mg/kg/day for two weeks) simultaneously with P. berghei infection showed significant protection against hepatic damage in Mastomys natalensis. The increased levels of serum glutamate oxaloacetate
The aim of the study was to assess the protective effect of Picrorhiza kurroa hydroalcoholic extract (PCK), a glycoside-rich extract, against potassium dichromate (PDC)-induced liver oxidative stress in Wistar albino rats. Thirty-six male Wistar rats were divided into six groups: the control group
Picroliv, a standardized extract from the plant Picrorhiza kurrooa containing active constituents, showed a significant dose dependent (3-12 mg/kg p.o. x 7) protective activity against galactosamine-induced hepatic damage in rat as evaluated on the isolated hepatocytes (ex vivo) preparation. It
Perfusion of liver of rats toxicated with galactosamine or thioacetamide with a 0.02% solution of picroliv (glycoside fraction of Picrorhiza kurroa) for 30 min (1 ml/min; 6 mg/rat), significantly reversed toxicant-induced changes in the activities of several enzymes. Galactosamine induced increases
Picroliv, the active constituent of P. kurrooa, showed a dose dependent (1.5-12 mg/kg, po for 7 days) hepatoprotective activity against oxytetracycline induced hepatic damage in rat. It increased the number of viable hepatocytes (ex-vivo) significantly. Increase in bile volume and its contents in
Administration of carbon tetrachloride to normal rats increased activities of hepatic 5(1)-nucleotidase, acid phosphatase, acid ribonuclease while the activities of succinate dehydrogenase, glucose 6-phosphatase, superoxide dismutase and cytochrome P450 were decreased. Levels of lipid peroxides,
Picroliv, an iridoid glycoside mixture prepared from the roots and rhizomes of Picrorhiza kurroa was found to be an effective inhibitor of hepatocarcinogenesis induced by N-Nitrosodiethylamine (NDEA) in rats. Animals administered with NDEA had large hepatic nodules and the liver weight was increased
The therapeutic efficacy of Picroliv--a standardized extract of Picrorhiza kurroa--was investigated in male rats exposed to CdCl2 (0.5 mg/kg, sc), 5 days/week for 18 weeks. Picroliv at two doses (6 and 12 mg/kg, po) was given to the cadmium (Cd)-administered group for the last 4 weeks (i.e., weeks
Thioacetamide (100 mg/kg), when administered to normal rats, caused a significant increase in the activities of 5'-nucleotidase and gamma-glutamyl transpeptidase and a decrease in the activities of glucose 6-phosphatase and succinate dehydrogenase enzymes in the liver. DNA, RNA, and proteins were
