Few studies have examined the effects of platelet-rich plasma (PRP) on intestinal anastomotic healing. The applied preparation methods and PRP concentrations used in the few studies that have been carried out varied markedly. Therefore, the positive effects of PRP on the anastomotic healing process remain unclear. The aim of this study is to examine the effects of different concentrations of PRP on intestinal anastomotic healing. ⋯ PRP concentration plays a crucial role in the efficacy of PRP. PRP might exert positive effects on intestinal anastomotic healing in a dose-dependent manner up to a certain level, but adverse effects occur when it is highly concentrated. The essential PRP action appears to be driven by the platelets themselves.

Acute kidney injury (AKI) is common in the intensive care unit, and one of its primary causes is renal ischemia-reperfusion (I/R) injury. Human atrial natriuretic peptide (hANP) exerts various pharmacologic effects, including renal protection. In the present study, we evaluated the renal protective effect of hANP in a rat model of renal I/R. ⋯ Our findings indicate that hANP may be effective in the treatment of various types of I/R injuries.
