...G.R. Ambler; B.H. Breier; S.N. McCutcheon; P.D. Gluckman To further evaluate the role of growth hormone (GH) in the neonatal period, the effects of GH or insulin-like growth factor 1 (IGF-1) administration were studied in the neonatal GH-defïcient rat. Groups of pups from newborn litters were...

...Alan N. Elias; Nosratola D. Vaziri; M.R. Pandian; Krish Iyer; Mohammad A. Ansari The role of dopamine in the dysregulation of TSH secretion in uremic male rats was investigated using the dopamine antagonist, pimozide. In order to obviate the effect of weight loss due to uremia-induced anorexia...

...Jelle Wiersma; Jan Kastelijn The temporal effects of intracerebroventricular (icv) infusion of prolactin (PRL) on endogenous PRL secretion was investigated in intact, freely moving, cycling rats. An icv infusion of 10 ng or 100 ng rat-PRL/min from 13.00 to 17.00 h during the proestrous afternoon...

...Elżbieta Zacny; Jan Bugajski In conscious, nonstressed rats clonidine given intracerebroventricularly (i.c.v.) increased the pituitary-adrenocortical response evaluated indirectly from corticosterone concentration. The maximum significant increase occurred 60 min after a dose of 10 µg. The α 2...

...F. Geisthövel; G. Brabant; E.J. Wickings; E. Nieschlag The age dependence of Leydig cell function was investigated in rats from prepuberty (15 days) to senescence (39 months). Serum LH, serum and testicular testosterone were measured by radioimmunoassay. The binding capacity and affinity of LH/hCG...

...E. Heinze; W. Kleinert; K.H. Voigt In the present experiments the effect of an intravenous glucose (0.5 g/kg body weight) and an intravenous glibenclamide (1 mg/kg body weight) injection on insulin release was studied in conscious rats shortly after hypophysectomy. 1 and 5 days after removal...

...S. Feldman; N. Conforti To elucidate the role of limbic structures in the negative feedback regulation of corticoids of adrenocortical function, the effect of dexamethasone on adrenocortical responses to ether stress was studied in intact and lesioned rats. In animals with septal and preoptic...

...Rosemaria Liske; Kurt Reber NSILA-S was localized by immunofluorescent antibody staining in the exocrine part of the pancreas and the submaxillary salivary gland of the rat, where part of the cells give positive reactions. To a lesser degree it was demonstrated in the kidney, where some – probably...

...Gene B. Fuller; Robert O. Wilson Cholesterol and cholesterol esters were measured on day 90 in the plasma and aortas of rats treated on day 4 as follows: control, gonadectomy, testosterone propionate (TP), estradiol-17 β (E). Sex differences were observed in sterol concentrations of control animals...

...T. Jolin Present results show that ether anesthesia raises the mean plasma insulin levels and the variability of the individual data around the mean in rats under different experimental conditions. Previous results [6, 7] obtained in ether-anesthetized rats, showing that the plasma insulin levels...

... of a continuous infusion of human recombinant IL-1β (rIL-1β) on circulating PTH during a 14-day period in 7-week-old female rats. This time interval was chosen in order to exclude initial hypercalcemia and to enable data collection under steady-state conditions. Five groups of 20 animals each had miniosmotic...

...J. De Schepper; X. Zhou; S. De Bock; J. Smitz; O. Louis; E. Hooghe-Peters; Y. Vandenplas In a group of 15 male Wistar rats overfed with cafeteria foods (delivering a mean fat percentage of 60%) during 5 months from the age of 8 weeks and in a control group of 15 rats fed with a standard chow...
