Tissue glycogen content and glucose intolerance

Study on the Effects of Chloroformic Extract of Securigera Securidaca on Serum Glucose Level and Liver Glycogen Content of Mice

Although Securigera securidaca (Ss) has long been known for its hypoglycemic effect, the precise nature of its effective component(s) and the involved mechanisms have not been investigated yet. This study investigated the effect of chloroformic extract of securigera securidaea seed on fasting serum glucose and glucose tolerance test, body weight, food consumption and liver glycogen content. Chl...

Hyperinsulinemia and Glucose Intolerance

Contraction-stimulated muscle glucose transport and GLUT-4 surface content are dependent on glycogen content.

The influence of muscle glycogen content on basal and contraction-induced glucose transport and cell surface GLUT-4 content was studied in rat skeletal muscle. Wistar rats were preconditioned by a combination of swimming exercise and diet, resulting in 40% lower (LG) or threefold higher (HG) muscle glycogen content compared with nonexercised controls (NG). At rest and during contractions, 2-deo...

High liver glycogen in hereditary fructose intolerance.

A case of hereditary fructose intolerance is reported in a girl aged 2 years at the time of her death. She had apparently progressed normally until the age of 14 months. At 19 months she was admitted to hospital with failure to thrive, hepatomegaly, and superficial infections. Investigations revealed hypoglycaemia, persistent acidosis, aminoaciduria, and a high liver glycogen level which sugges...

Glycogen content and contraction regulate glycogen synthase phosphorylation and affinity for UDP-glucose in rat skeletal muscles.

Glycogen content and contraction strongly regulate glycogen synthase (GS) activity, and the aim of the present study was to explore their effects and interaction on GS phosphorylation and kinetic properties. Glycogen content in rat epitrochlearis muscles was manipulated in vivo. After manipulation, incubated muscles with normal glycogen [NG; 210.9 +/- 7.1 mmol/kg dry weight (dw)], low glycogen ...
