Ingestive behaviour of starved rats after single intraperitoneal injection of fresh plasma from well-fed rats.

چکیده
Ingestive behaviour of control and experimental rats following 96 hours of starvation was studied. The control animals were injected normal saline intraperitoneally (I.P.) whereas the experimental animals were injected I.P. with fresh plasma obtained from well fed rats. Having been presented with food 15 minutes after the injections, the food intake (Gms +/- SEM) of control animals for the first five hours after injection was 6.00 +/- 0.44, whereas, the intake in experimental animals for the same period was 0.55 +/- 0.05. The food intake was significantly suppressed for the next three days, attaining the normal values by the 4th day. Since all the rats were starved prior to injection, all of them increased in weight during the four days of study, but the increase seen in the experimental group was much subdued. Therefore the plasma factor, suppresses not only the food intake but also the gain in body weight.

Effect of epinephrine and cortisol on fasting-induced ghrelin secretion in male rats fed different levels of their energy requirement
Introduction: ghrelin is a potent orexigenic agent in rodents and humans. Some studies have shown that ghrelin participates in the adaptive response to weight loss and plasma concentration of ghrelin rises with dieting. On the other hand, weight loss and fasting is accompanied by increased levels of epinephrine and cortisol. In this study, we investigated the effects of epinephrine and corti...
متن کاملArteriovenous glucose differences across the mammary gland of the fed, starved, and re-fed lactating rat.
Arteriovenous glucose difference across the mammary gland of the lactating rat was used as an 'instantaneous' monitor of mammary glucose uptake. Plasma [glucose] and arteriovenous glucose difference varied according to whether Halothane, diethyl ether or sodium pentobarbitone anaesthesia was used. In pentobarbitone-treated rats a 60% glucose extraction in the fed state decreased to 5% after 18 ...

Background: There is not any in vivo studies that shows inducing of euglycemia by vanadyl is independent from plasma insulin. Therefore in the present study we planned to investigate the antidiabetic effects of vanadyl in diabetic rats. Materials and Methods: Rats became severely diabetic by an IV injection of 50-55mg/kg streptozotocin (STZ), 15 days after the injection, the blood glucose of ...
