Abstract

To observe the therapeutic effects of Saussurea involucrata (Sau) injection against severe acute pancreatitis (SAP)-induced brain injury. Sodium taurocholate-induced SAP-modeled rats were equally randomized into an SAP model group (SAP group) and a Sau treated group (Sau  +  S group). Healthy rats were equally randomized into a Sau treated group (Sau  +  H group) and a sham operation group (SO group). Serum amylase levels, endothelin-1 (ET-1) and nitric oxide (NO) contents were determined by optical turbidimetry, ELISA and nitrate reductase method respectively. Western blot was used to detect protein expression levels of phosphatidylinositol 3-kinase (PI3K), protein kinase B (Akt), ET-1, inducible nitric oxide synthase (iNOS) and endothelial NOS (eNOS) while mRNA levels of these biomarkers in brain tissue were measured by quantitative real-time PCR. Furthermore, pathological changes, as well as all above indexes of pancreas and brain, were observed at 6, 24 and 48 h after administration. There was a significant difference in mortality between SAP and Sau  +  S groups (P  <  0.05). Serum amylase levels, ET-1 and NO contents, ET-1/NO ratio, relative expression levels of ET-1 and iNOS protein/mRNA of brain tissue in Sau + S group ...Continue Reading

brain injury after impact to the head is due to both immediate mechanical effects and delayed responses of neural tissues.

AKT Pathway

This feed focuses on the AKT serine/threonine kinase, which is an important signaling pathway involved in processes such as glucose metabolism and cell survival.
