Minoxidil sulfate and pinacidil, well-known activators of the ATP-sensitive K+ (KATP) channel, induce hair growth in clinical studies. The opening of K+ channels is thought to be an important mechanism in the regulation of hair follicles. In the present study, we used the patch clamp technique to characterize the K+ channels and tested the effect of K+(More)
Minoxidil sulfate and pinacidil are K channel openers and are considered to promote hair growth. However, there have been no studies on the single channel current of isolated cells from hair follicles. Therefore, we characterized the single K channel current of outer root sheath cells and dermal papilla cells and the effect of K channel openers on K(More)
This study was conducted to investigate the autophagic response of Sertoli cells (SCs) to acute ethanol toxicity using in vivo and in vitro models. Adult Wistar rats were intraperitoneally injected with either 5 g/kg ethanol or phosphate-buffered saline (for the control group) and sacrificed 0, 3, 6 and 24 h after injection. Compared to the control group,(More)
