carbosulfan (2,3-dihydro-2,2dimethyl-7-benzofuronyl [(dibutyl amino) thio] methyl] a carbamate insecticide and acaricide was administered orally at an effective dose of 48 mg/kg/day to albino mice for 5, 10, 20 and 30 days .control mice received similar quantities of olive oil. daily body weights were recorded and mice were sacrificed after 24 hours after the terminal exposure. the histologic e...

The effects of in ovo feeding of carbohydrates on hatchability, BW, yolk sac weights (YSW), pectoral muscle weights (PMW), liver and pectoral muscle glycogen concentration, serum glucose level, and hepatic glucose-6-phosphatase activity of domestic pigeons, hatched from eggs laid by a 40-wk-old breeder flock, were investigated. At 14.5 of incubation, fertile eggs were injected with 200 μL of 1....

To test the hypothesis that cortisol and epinephrine have direct regulatory roles in muscle glycogen metabolism and to determine what those roles might be, we developed an in vitro white muscle slice preparation from rainbow trout (Oncorhynchus mykiss Walbaum). In the absence of hormones, glycogen-depleted muscle slices obtained from exercised trout were capable of significant glycogen synthesi...

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...

In humans af ter short-term maximal exercise muscle glycogen levels are reduced to 75-80% of the initial muscle content. However, data obtained from maximally activated rat muscles show th at after only a few seconds of exercise total glycogen depletion had occurred in many fast fibres . It is argued that during short maximal exercise, effects of glycogen depletion in some fibres may lead to th...

Effect of drug praziquantel (PZQ) and C. longa extract on S. mansoni infected mice is reported. The level of glycogen, alkaline and acid phosphatases (ALP and ACP respectively), and body weight, liver weight and liver weight/body weight ratio were studied in mice infected with S. mansoni. ALP level was increased after infection. C. longa treated mice showed marked reduction in ALP level more th...

We have investigated the cause of defective glycogen synthesis in hepatocyte preparations enriched with cells from the periportal or perivenous zones obtained by the methods of Lindros & Penttila [Biochem. J. (1985) 228, 757-760] and of Quistorff [Biochem. J. (1985) 229, 221-226]. A modified procedure which yields hepatocytes capable of consistent rates of glycogen synthesis is described, and t...
