Study of the early blood glucose response of mice to alloxan

Abstract

The initial hyperglycemia in alloxan-treated mice was decreased by adrenalectomy and hypophysectomy, and abolished by occlusion of the hepatic blood flow for 5 min. or treatment with insulin after alloxan injection. No effect on the initial hyperglycemic response to alloxan was found in mice pretreated with phentolamine, or in those given alloxan after sham operation or after removal of ligatures for temporary occlusion of hepatic artery and portal vein. The concentrations of serum insulin and liver glycogen were decreased one and four hours after alloxan injection. The initial hyperglycemia is believed to be due to inhibition of insulin secretion by the B-cells and to the mobilization of glycogen from the liver. Pituitary and adrenocortical activity may contribute to this hyperglycemia. The origin of the hypoglycemic phase does not seem to be pancreatic, but may be hepatic.

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Torsion dystonia is a movement disorder characterized by loss of control of voluntary movements appearing as sustained muscle contractions and/or abnormal postures. Here is the latest research.

Archaeal RNA Polymerase

Archaeal RNA polymerases are most similar to eukaryotic RNA polymerase II but require the support of only two archaeal general transcription factors, TBP (TATA-box binding protein) and TFB (archaeal homologue of the eukaryotic general transcription factor TFIIB) to initiate basal transcription. Here is the latest research on archaeal RNA polymerases.

Alzheimer's Disease: MS4A

Variants within the membrane-spanning 4-domains subfamily A (MS4A) gene cluster have recently been implicated in Alzheimer's disease in genome-wide association studies. Here is the latest research on Alzheimer's disease and MS4A.

Central Pontine Myelinolysis

Central Pontine Myelinolysis is a neurologic disorder caused most frequently by rapid correction of hyponatremia and is characterized by demyelination that affects the central portion of the base of the pons. Here is the latest research on this disease.
