Eighteen rats were divided into three equal groups. The first group was closed orally with quassin, the second group was dosed with quassin after the gut flora were suppressed by difierent antibiotics, and the third group was served as a control. Food intake, water intake, and change in body weight were measured daily before dosing, during two weeks of dosing, and during one week after stopping dosing. Two eats from each group were killed at the end of each week, and stomach, liver, and kidney were collected for histopathologic examination. The results show a significant decline in daily food intake and daily change in body weight, and a significant increase in daily water intake in both dosed groups during the dosing period. Microscopic lesions were seen in the kidneys of both dosed rats group killed at the end of first and second week

AbstractObjective. The aim of the present study was to assess the effect of the PYY3–36, as a potential therapy for the type 2 diabetes mellitus (T2DM), induced by high fat diet (HFD) and an intraperitoneal (i.p.) administration of streptozotocin (STZ) in albino rats.Methods. Forty adult male albino Wistar rats were divided into: 1) control group (C, in which the rats were fed with a standard diet and received vehicle; 2) diabetic group (D, in which T2DM was induced by feeding the rats with HFD for four weeks followed by a single i.p. injection of 35 mg/kg STZ, this group was also allowed to have HFD till the end of the study; and 3) D+PYY3–36 group (in which the diabetic rats were treated with 50 µg/kg i.p. PYY3–36 twice a day for one week). Food intake, water intake, body weight (b.w.), visceral fat weight (VFW), liver glycogen content, serum levels of glucose, insulin, and interleukin-6 (IL-6), were measured. Homeostatic-model assessment of insulin resistance (HOMA-IR) was estimated. The gene expression of the hypothalamic neuropeptide Y (NPY) and visceral nuclear factor kappa B (NF-κB) were assessed by a reverse transcription polymerase chain reaction (RT-PCR).Results. The PYY3–36 administration to the diabetic group of rats significantly increased the serum insulin levels and liver glycogen content, decreased the body weight, VFW, food intake, water intake, serum levels of the glucose, IL-6, and HOMA-IR. It also decreased the expression of both the hypothalamic NPY and the visceral fat NF-κB.Conclusion. With respect to the fact of improved insulin release and enhanced insulin sensitivity (an effect that may be mediated via suppressing accumulation of visceral fat and inflammatory markers), in the rats treated with PYY3–36, the PYY3–36 might be considered for the future as a promising therapeutic tool in T2DM.

We recently reported that intracerebroventricular infusions of ANG II decreased food intake and increased energy expenditure in young rats. The aim of the present study was to determine if intracerebroventricular ANG II has similar effects in adult rats. The time course of the effect was also investigated with the idea that at earlier time points, a potential role for increased hypothalamic expression of corticotropin-releasing hormone (CRH) in the anorexia could be established. Finally, the contribution of ANG II-induced water drinking to the decrease in food intake was directly investigated. Rats received intracerebroventricular saline or ANG II using osmotic minipumps. Food intake, water intake, and body weight were measured daily. Experiments were terminated 2, 5, or 11 days after the beginning of the infusions. ANG II (∼ 32 ng·kg−1·min−1) produced a transient decrease in food intake that lasted for 4–5 days although body weight continued to be decreased for the entire experiment most likely due to increased energy expenditure as evidenced by increased uncoupling protein-1 mRNA expression in brown adipose tissue. At 11 and 5 days, the expression of CRH mRNA was decreased. At 2 days, CRH expression was not suppressed even though body weight was decreased. The decrease in food intake and body weight was identical whether or not rats were allowed to increase water consumption. These data suggest that in adult rats ANG II acts within the brain to affect food intake and energy expenditure in a manner that is not related to water intake.

This study examined the effects of selected groups of essential amino acids (EAAs), given by gavage, on short-term food and water intake. Amino acid groups were selected on the basis of their common physiologic functions in relation to current hypotheses on the role of amino acids in food intake control, and the quantities given were based on the proportions in 1.5 g of the EAA content of albumin. The complete EAA mixture (1.5 g) suppressed food intake by an average of 60 and 37% during the 1st and 2nd h of feeding, respectively, but had no influence on feeding in the subsequent 12 h. Total daily (14 h) intake was decreased by 9%. With the exception of the aromatic amino acid (Phe + Tyr + Trp, 0.34 g) group, all groups significantly decreased food intake by a comparable magnitude (32%) during the 1st h. In this time period, rats given the EAAs, Arg + Met + Val (0.38 g), and Arg + His + Lys (0.44 g) mixtures increased their water intake, whereas intake by rats given the Phe + Tyr + Trp + Thr (0.46 g) and Ile + Leu + Val (0.45 g) mixtures was unchanged. Thus, the food intake suppression caused by EAAs was not accounted for by an equal effect of its component amino acid groups. As well, food intake suppression by amino acid groups was not explained by increased water consumption, nor was it simply related to the quantity of nitrogen provided by the treatment.Key words: food intake, water intake, essential amino acids.
