Hepatic necrosis induced by norepinephrine in rabbits.

Numai utilizatorii înregistrați pot traduce articole

Extensive hepatic necrosis was produced in rabbits 48 hr following infusion of a cardiopathogenic dose of norepinephrine (NE, 2 micrograms/kg/min for 90 min). Livers had necrotic areas of varying sizes and gross appearances. Histologically, the lesions were areas of varying sizes and gross

Induction of two different modes of cell death, apoptosis and necrosis, in rat liver after a single dose of thioacetamide.

Numai utilizatorii înregistrați pot traduce articole

A sequential study of the appearance of liver cell death after thioacetamide (TH) administration was performed in male Wistar rats. Within 3 hours of a single dose of TH, occurrence of cell death by apoptosis was evident around the centrilobular area. Light as well as electron microscopic

Effect of dimethyl sulphoxide on oxidative stress, activation of mitogen activated protein kinase and necrosis caused by thioacetamide in the rat liver.

Numai utilizatorii înregistrați pot traduce articole

Thioacetamide (400 mg/kg body weight, i.p.) was administered to rats. After 12 h the activity of plasma glutamate-oxaloacetate transaminase (GOT) and glutamate-pyruvate transaminase (GPT) was significantly higher than that of the control group, and after 24 h plasma GOT and GPT activities strongly

The sequential analysis of liver cell necrosis: inhibition of diethylnitrosamine- and dimethylnitrosamine-induced acute liver cell death by posttreatment with diethyldithiocarbamate.

Numai utilizatorii înregistrați pot traduce articole

Posttreatment with diethyldithiocarbamate (DEDTC) largely prevented the development of acute hepatocellular necrosis induced by diethylnitrosamine (DEN) and dimethylnitrosamine (DMN) in male Fischer rats as monitored by the release of glutamate-pyruvate transaminase and sorbitol dehydrogenase into

Comparison of hepatotoxicity of 1,2-, 1,3- and 1,4-dibromobenzenes: the dynamics of changes of selected parameters of liver necrosis in acute poisoning in mice.

Numai utilizatorii înregistrați pot traduce articole

Various doses of dibromobenzene isomers (1,2-dBB, 1,3-dBB, 1,4-dBB) were administered (i.p.) to BALB mice. The levels of reduced glutathione (GSH) and malondialdehyde (MDA) in the liver, and glutamate-pyruvate transaminase (GPT) (EC.2.6.1.2) gamma-glutamyltransferase (gamma-GT) (EC.2.3.2.2) and

D-galactosamine-induced mouse hepatic apoptosis: possible involvement with tumor necrosis factor, but not with caspase-3 activity.

Numai utilizatorii înregistrați pot traduce articole

We investigated whether tumor necrosis factor (TNF) and caspase-3 activity are involved in the induction of hepatocellular apoptosis in D-galactosamine (D-GalN)-induced hepatotoxicity in mice. Acute hepatotoxicity was induced by the intraperitoneal injection of D-GalN into female BALB/c mice. D-GalN

Combined Effects of Vincristine and Quercetin in Reducing Isoproterenol-Induced Cardiac Necrosis in Rats.

Numai utilizatorii înregistrați pot traduce articole

Combined effects of vincristine and quercetin in the regulation of isoproterenol (ISO)-induced cardiac necrosis have been evaluated in rats. ISO administration (100 mg/kg, s.c., for two consecutive days) increased the levels of serum creatine kinase-MB (CK-MB), lactate dehydrogenase (LDH), glutamate

Cardioprotective effect of vincristine on isoproterenol-induced myocardial necrosis in rats.

Numai utilizatorii înregistrați pot traduce articole

This study investigated the protective effect of vincristine (VCR) on isoproterenol (ISO)-induced cardiac necrosis (CN) in rats. Animals (n=7 in each group) were pretreated with vincristine (25µg/kg) intraperitoneal (i.p.) daily in 5-day cycles with 2 days pause between cycles using a 5-day-on,

Protection of lethal toxicity of endotoxin by Salvia miltiorrhiza BUNGE is via reduction in tumor necrosis factor alpha release and liver injury.

Numai utilizatorii înregistrați pot traduce articole

Lipopolysaccharide (LPS) has been implicated as one of the major cause of Gram-negative bacteria-induced sepsis that are life-threatening syndromes occurring in intensive care unit patients. Many natural products derived from medicinal plants may contain therapeutic values on protecting

Plasma ornithine carbamyl transferase level as an indicator of ischaemic injury of rat liver.

Numai utilizatorii înregistrați pot traduce articole

The activity of ornithine carbamyl transferase (OCT) and glutamate pyruvate transaminase (GPT) in serum has been correlated with the extent of necrosis 24 h after different periods of ischaemia in rat liver. The extent of necrosis has been quantified as the volume density of necrosis in the total

Ameliorative potential of whey protein hydrolysate against paracetamol-induced oxidative stress.

Numai utilizatorii înregistrați pot traduce articole

The aim of the present study was to validate the antioxidant effect of whey protein hydrolysate (WPH) using a small animal model. Paracetamol is common drug that is safe at therapeutic levels; however, an overdose causes oxidative stress, which may lead to potential hepatic and renal necrosis. The

Postnatal mice have low susceptibility to paracetamol toxicity.

Numai utilizatorii înregistrați pot traduce articole

The hepatotoxicity of paracetamol in mice of 2, 3, 8-10, 24-26, 32-34, and 52-54 wk of age was determined by lethality data, histopathologic examination of the liver, and appearance of glutamate-pyruvate transaminase and glutamate-oxaloacetate transaminase activities in the plasma over an 8-h

The addition of protein-bound amino acids in low-protein diets improves the metabolic and immunological characteristics in fifteen- to thirty-five-kg pigs.

Numai utilizatorii înregistrați pot traduce articole

This study was to evaluate the effects of supplementation of AA form (crystalline vs. protein bound) in low-protein diets on growth, metabolic, and immunological characteristics of pigs. A total of 80 barrows (PIC 327 × 1050; 15.57 ± 0.13 kg BW and 48 ± 2 d of age), housed in 4 pigs per pen with 5

Stimulation of DNA synthesis after a single administration of cadmium nitrate.

Numai utilizatorii înregistrați pot traduce articole

The effect of a single intravenous (i.v.) injection of cadmium nitrate was investigated in livers of male Wistar rats. A significant increase in liver weight, accompanied by an elevation of total hepatic DNA content was observed. DNA synthesis as measured by the incorporation of [3H]thymidine, was

Liver cell proliferation induced by a single dose of lead nitrate.

Numai utilizatorii înregistrați pot traduce articole

Treatment of male Wistar rats with a single dose of lead nitrate caused a marked enlargement of the liver, which reached its maximum 3 days after the administration of the metal salt. This grossly anatomic effect was accompanied by biochemical changes such as an increase in total protein and DNA
