Male Sprague-Dawley rats were fed control diet or diet containing 0.05% nafenopin (NAF) or 0.025% WY-14,643 (WY) and male Syrian hamsters were fed control diet or diet containing 0.25% NAF or 0.025% WY for periods of 1, 15, 40, and 60 weeks. Both NAF and WY produced a sustained increase in liver weight and induction of peroxisomal fatty acid beta-oxidation in the rat and Syrian hamster. Replica...

BACKGROUND Following the production of Syrian gel, the scientists from Atomic Energy Commission of Syria, researchers in Yazd Atomic Energy Commission Radiation Processing Center in Iran, have manufactured a hydrogel wound dressing. This study was conducted to evaluate and compare the efficacy of these two hydrogels. METHODS In this study, 32 male Wistar rats underwent a full thickness circul...

Rats and other rodents are exposed by inhalation to identify agents that might present hazards for lung cancer in humans exposed by inhalation. In some cases, the results are used in attempts to develop quantitative estimates of human lung cancer risk. This report reviews evidence for the usefulness of the rat for evaluation of lung cancer hazards from inhaled particles. With the exception of n...

A complementary DNA (cDNA) library was prepared from messenger RNA (mRNA) isolated from Syrian hamster islets. Bacterial colonies containing hamster preproinsulin cDNA were identified by cross-hybridization with the human preproinsulin gene. The sequences of two of these established the complete sequence of Syrian hamster preproinsulin mRNA and predicted the sequence of the protein. Hamster pre...

the culture results of 203 cases with different wounds were studies 150 of the latter were burn cases (mainly second and third degree burns), and 53 were of other types (surgical, traumatic, ect). four subtypes of bacillus cereus were isolated upon culture, and the different toxins produced in dht broth with 0.1% glucose were assessed. the lethal toxin was injected intravenously to syrian rats,...

Fat intake and obesity are positively correlated with pancreatic cancer in humans. N-nitrosobis(2-oxopropyl)amine (BOP) induces pancreatic ductal adenocarcinomas limited to Syrian golden hamsters, other rodents not being susceptible. In the present study, we found markedly high levels of serum triglycerides (TGs) and total cholesterol (TC) in Syrian golden hamsters, but not C57BL/6 mice, ICR mi...

A number of phthalate esters and related chemicals were tested for mutagenicity in Salmonella typhimurium. The chemicals were tested blind in three laboratories by a preincubation modification of the Ames Salmonella/mammalian microsome test using S-9 prepared from Aroclor-induced rats and Syrian hamsters. All chemicals tested were judged to be nonmutagenic.

Elastase intratracheal instillation induces early emphysema in rodents. However, Syrian Golden hamsters develop more severe emphysema than Sprague-Dawley rats. We have reported species differences in oxidant/antioxidant balance modulating antiprotease function early after instillation. We now hypothesize that other components of the initial lung response to elastase might also be species-depend...

Gemfibrozil is a widely prescribed hypolipidemic agent in humans and a peroxisome proliferator and liver carcinogen in rats. Three-month feed studies of gemfibrozil were conducted by the National Toxicology Program (NTP) in male Harlan Sprague-Dawley rats, B6C3F1 mice, and Syrian hamsters, primarily to examine mechanisms of hepatocarcinogenicity. There was morphologic evidence of peroxisome pro...
