N,N'-dimethylnitrosourea-induced tumors in mice and Syrian hamsters.
Carcinogenic effect of N, N’-dimethylnitrosourea (DMNU) on mice and hamsters was studied. Repeated subcutaneous injections　of DMNU resulted in the induction of malignant lymphomas with an　incidence of 100 per cent in adult C3HjBifBjKi mice and induced　malignant tumors of　forestomach, mammary gland and uterus with a　high incidence in adult hamsters. Control ani...

15 صفحه اولPheromone-induced anorexia in male Syrian hamsters.
Transition from long days (LDs) to short days (SDs) triggers seasonal obesity in Syrian hamsters. We report here that SD-exposed males housed near females exhibit obesity resistance, episodic weight loss, and reduced adiposity. Negative energy balance is achieved by reduced eating, elevated motor activity, and increased caloric efficiency without metabolic compensation. Circulating leptin, insu...
متن کاملGeniculo-hypothalamic tract lesions block chlordiazepoxide-induced phase advances in Syrian hamsters.
Administration of the benzodiazepine triazolam at the appropriate time in the circadian cycle has been shown to induce phase shifts in hamster circadian rhythms. These phase shifts can be blocked by geniculo-hypothalamic tract (GHT) ablation or by restraint of activity. The present study examined the effects of the benzodiazepine chlordiazepoxide on running-wheel activity rhythms of hamsters. T...
متن کاملPineal-induced depression of free thyroxine in Syrian hamsters.
Blind hamsters had no alteration of the dialyzable fraction of serum thyroxine (T4) but had depressed total and free T4 concentrations compared to controls. Prevention of the effects of blinding by pinealectomy indicates pineal influence on circulating free T4 concentration. Parallel changes in free T4 and the free T4 index indicate adequacy of the index in representing pineal-induced changes i...
