Glucose turnover during pregnancy in anaesthetized post-absorptive rats.
نویسندگان
چکیده
During pregnancy the decline in blood [glucose] does not result from the increased distribution space of glucose. The absolute rate of glucose turnover increases in late pregnancy in parallel with the rise in the mass of the conceptus. Nevertheless, glucose turnover per kg body wt. is not increased in late pregnancy, since the lower blood [glucose] decreases glucose utilization by maternal tissues.

Initial glucose kinetics and hormonal response to a gastric glucose load in unrestrained post-absorptive and starved rats.
A gastric [U-14C]glucose load (4.8 mg/g body wt.) was delivered to unrestrained post-absorptive or 30 h-starved rats bearing peripheral and portal vein catheters and continuously perfused with [3-3H]glucose, in order to compare their metabolic and hormonal responses. In the basal state, portal and peripheral glycaemia were less in starved rats than in rats in the post-absorptive period (P less ...
متن کاملThe effect of pregnancy and lactation on food intake, gastrointestinal anatomy and the absorptive capacity of the small intestine in the albino rat.
1. Food consumption, live weight, anatomical measurements on the gut organs and the absorptive capacity of the small intestine for L-leucine and D(plus)-glucose were made on virgin (control), pregnant and lactating albino rats. 2. Food intake increased by approximately 60% during pregnancy and a further 250% during lactation. 3. Pregnancy did not markedly influence the gross anatomy of the gast...

L-[U-14C]Threonine was infused at a steady rate to non-anaesthetized rats starved for 1 or 3 days and to diabetic rats starved for 1 day. The rates of turnover of threonine, calculated from the equilibrium specific radioactivity (SA) of plasma threonine, were 5.79 +/- 1.00, 11.67 +/- 1.43 and 13.35 +/- 1.85 mumol/min per kg body wt. in 1-day-starved, 3-day-starved and diabetic rats respectively...
متن کاملEffect of maternal variable stress on oxidative status and glucose metabolism in pubertal male rats
Introduction: Metabolic disorders are affected by negative stress experiences in the early stages of life. Accordingly, in this study, the effects of stress during pregnancy on oxidative status and glucose homeostasis in pubertal male Wistar rats were investigated. Materials and Methods: After pregnancy, female rats (200±30 g) were divided into 2 groups (6 rats per group) of stress and non-stre...
متن کاملP-143: Histomorphometric Evaluation ofSmall Intestine during Pregnancy in Rat
Background: Food intake of rats increases during pregnancy. This requires changes in the structure of the small intestine to absorb additional food. The aim of the present study was to investigate the morphological changes in the layers of small intestine in rats during pregnancy. Materials and Methods: Duodenum, jejunum and ileum of 18 pregnant Sprague-Dawley rats (day 7, 14 and 21 pregnancy) ...
