Fertilizing capacity of the cryptorchid rat.
Rats were surgically made bilaterally cryptorchid and after 4-8 days the testes were returned to the scrotum. After 70 days fertility was tested by pairing with females. Fertility was restored in 5/6 rats with testes cryptorchid for 4 or 5 days, but only 2/9 were fertile when the duration of cryptorchidism was 6-8 days. The sterility was due to irreversible degeneration of the spermatogonial st...
متن کاملGlucose and glutamine metabolism in rat thymocytes.
The metabolism of glucose and glutamine in freshly prepared resting and concanavalin A-stimulated rat thymocytes was studied. Concanavalin A addition enhanced uptake of both glucose and glutamine and led to an increase in oxidative degradation of both substrates to CO2. With variously labelled [14C]glucose, it was shown that the pathways of glucose dissimilation were equally stimulated by the m...
متن کاملGlycated albumin suppresses glucose-induced insulin secretion by impairing glucose metabolism in rat pancreatic β-cells
BACKGROUND Glycated albumin (GA) is an Amadori product used as a marker of hyperglycemia. In this study, we investigated the effect of GA on insulin secretion from pancreatic β cells. METHODS Islets were collected from male Wistar rats by collagenase digestion. Insulin secretion in the presence of non-glycated human albumin (HA) and GA was measured under three different glucose concentrations...
متن کاملGlucose metabolism and fructose synthesis in the diabetic rat lens.
A comparison of the uptake of glucose in vitro by lenses from normal and alloxan-diabetic rats involves the effect of secondary factors tuhich may obscure any effect of diabetes itself. These factors have been investigated and their influence evaluated. A procedure has been developed for the incubation of lens dispersions which yields values for glucose uptake and. lactate production within the...
متن کاملGlucose metabolism in the newborn rat. Hormonal effects in vivo.
1. The concentrations of liver glycogen and plasma d-glucose were measured in caesarian-delivered newborn rats at time-intervals up to 3h after delivery after treatment of the neonatal rats with glucagon, dibutyryl cyclic AMP, cortisol or cortisol+dibutyryl cyclic AMP. Glycogenolysis was promoted by glucagon or dibutyryl cyclic AMP in the third hour after birth but not at earlier times. Cortiso...
