title: Blood glucose profiles in diabetic rodents using different insulin preparations.
abstract: The aim of the present study was to evaluate several long-acting insulin preparations for their ability to normalize the blood glucose profile of rats and mice with streptozocin-induced diabetes mellitus. The single injection of a long-acting zinc insulin (CAS 8049-62-5) suspension or insulin glargine (CAS 160337-95-1) in both species induced a steep to moderate fall in blood glucose concentration. Blood glucose was then normalized for 2-3 h, until 3 h after insulin injection blood glucose concentration tended towards levels before insulin application. In contrast, implants produced with a mixture of human insulin and palmitic acid micro-crystals normalized blood glucose profile over 24 h in both species at least 30 days after implantation. Therefore, these implants with a sustained release of insulin are suitable to control the blood glucose in diabetic rats and mice.
