It has been used by an injection under the skin since its introduction in 1922. However, it could possibly be taken any other way which bypasses the digestive system, such as by inhalation into the lungs, inhalation through the nose, by a skin patch, or even as a rectal suppository. ...
After injecting insulin, the pen has to be kept in place for some time. Many pens leak from the tip of the needle when the pen is removed from the injection site 7 seconds after the injection is finished. In one study only the Novopen 1.5ml and Novolet 1.5ml showed no leakage; eight...
Soon after the discovery of insulin it was found that it had a very short half-life after injection into animals. Subsequent studies showed that insulin is rapidly proteolyzed both in whole animals and with isolated cells. Indeed, every tissue and cell that responds to insulin can also degrade...

4b). The initial peak in d-glucose after l-glucose or vehicle injection (Fig. 4a) is a short-lived response related to the dosing (handling) of the animals. This response is not associated with NNC2215 as the same pattern is also seen in a similar l-glucose protocol testing the non-...
injection with 0.75 U kg À 1 insulin on 5 h-fasted mice 15 min after intraperitoneal treatment. Blood glucose (a) and insulin (b) concentrations (1: blue bars; vehicle: grey bars) were measured at the indicated time points. Insert represents AUC (0–165). Data are mean±s.e.m (...
Glucose levels during the insulin tolerance test were measured after intraperitoneal injection with 0.75 U/kg insulin. Values shown represent means ± S.E. *p < 0.05 vs. 0 min and †p < wild type, by Fisher’s PLSD. Full size image The ITT at the end of the 5-week study...
Intra- cerebroventricular injection of insulin was shown to improve the performance on an avoidance task (Park et al., 1995), although no effect on memory was found following intrahippocampal insulin injection in rats (Paulus et al., 2005). The observations that insulin, ins...
As a result, insulin injection significantly attenuated Bmal1 occupancy on the promoters of its target genes (Dbp and Nr1d1, Fig. 1e) and subsequently their transcription (Fig. 1f). In line with previously reported in vitro results19, we also found that insulin injection increased hepatic ...
