The Relation of Heart Weight to the Basal Metabolism as Varied by Thyroid Administration
نویسندگان
چکیده
A linear relationship exists in the albino rat between the heart weight and the basal metabolic rate when varied by the administration of active thyroid material. It is suggested that this increase in heart weight which follows the increase in metabolism after thyroid is in the nature of a simple work hypertrophy of the myocardium.

Effect of Thyroid Activity Modulation on Some Histological and Biochemical Aspects in Broiler Chicks
An experiment was conducted to investigate the effect of thyroid gland activity modulation (Hyper or hypothyroidism) on energy utilization in broiler chickens. Two hundred and forty one-day-old Cobb broiler chicks were distributed into three dietary metabolizable energy (ME) treatment groups (80 chicks each). The control group (E0) was fed basal diet (3150 kcal/kg diet), the second group (E1) w...

Although thyroid hormones are known to influence acid secretion, but exact mechanisms are not fully understood. So, in this experimental study carbachol, histamine, and pentagastrin were used to stimulate acid secretion in isolated stomach of hypo- and hyperthyroid rats and data were compared with controls. Each group consisted of 8 N-Mari rats from both sexes weighing 246 ± 5 g. Hypo- and hype...

Introduction: Leptin and Ghrelin are hormones that have been discovered in the last decade and were shown to be involved in appetite and metabolism regulation and body weight. Thyroid hormones are also involved in general metabolism and changes in their circulating levels bring about changes in appetite and body weight. Results of animal and human studies regarding Leptinlevel and its re...

Abstract Background: The thyroid hormones influence on all metabolic pathways. After heart surgery using cardiopulmonary bypass (CPB), serum T3 decreases and remains low for at least 24 hours. Several studies on pediatric have reported reduction of thyroid hormones after heart surgery. This study aimed to investigate the status of thyroid function tests in children with CPB surgery. Metho...

Fenfluramine, an anorexigenic agent, is widely used in the treatment of obesity. Besides its anorectic effect, it may also have some effects on general metabolism with the consequence of weight loss. In this study, the effect of fenfluramine on the concentrations of some parameters related to carbohydrate metabolism was investigated. It was shown that the serum insulin level was reduced by ...
