Sodium tanshinone IIA sulfonate improves inflammation, aortic endothelial cell apoptosis, disseminated intravascular coagulation and multiple organ damage in a rat heat stroke model
Abstract
The aim of the present study was to investigate the effects of sodium tanshinone IIA sulfonate (STS) on inflammatory responses, aortic endothelial cell apoptosis, disseminated intravascular coagulation (DIC) and multiple organ damage in an animal model of classic heat stroke (CHS). The rats in the heat stroke (HS) and STS‑treated heat stroke (STS‑HS) groups were placed into a pre‑warmed animal temperature controller (ATC) at 35˚C. The moment at which the rectal temperature reached 43.5˚C was considered as the time of onset of HS. In the HS groups, the rats were removed from the ATC and allowed to recover at 26˚C for 0, 2, 6 or 12 h. In the STS‑HS groups, the rats received femoral vein injections of 5‑40 mg/kg STS immediately following the onset of HS and were subsequently placed at a temperature of 26˚C to recover for 6 h. In the present study, the serum levels of tumor necrosis factor (TNF)‑α, interleukin (IL)‑1β and IL‑6 were assessed using ELISA, and the numbers of apoptotic aortic endothelial cells were investigated using terminal deoxynucleotidyl transferase deoxyuridine triphosphate nick‑end labeling combined with immunofluorescence. In the HS groups, the serum levels of TNF‑α, IL‑1β and IL‑6, as well as the numbers of ap...Continue Reading

Apoptosis
Apoptosis is a specific process that leads to programmed cell death through the activation of an evolutionary conserved intracellular pathway leading to pathognomic cellular changes distinct from cellular necrosis
Blood Clotting Disorders
Thrombophilia includes conditions with increased tendency for excessive blood clotting. Blood clotting occurs when the body has insufficient amounts of specialized proteins that make blood clot and stop bleeding. Here is the latest research on blood clotting disorders.
