The cytoprotective effect of NC-1300-O-3 and its mechanism of action were investigated. NC-1300-O-3 at doses of 3 and 10 mg/kg, p.o. significantly prevented the formation of gastric lesions by HCl.ethanol in rats, and its efficacy was not influenced by repeated administration for up to 4 weeks. The interaction between NC-1300-O-3 and necrotizing agents in(More)
The present study was undertaken to elucidate the possible effects of tanshinone VI, one of the extracts from the root of Salvia, on post-hypoxic recovery of cardiac contractile force. For this purpose, rat hearts were perfused for 45 min under reoxygenated conditions following 20-min hypoxic perfusion, and changes in tissue high-energy phosphates and(More)
β-TCP was implanted into bone defects of dog mandibles, and gene expression profiles were examined using DNA microarray. An implant drill was used to make bone defects, and then β-TCP was filled into bone defects. All specimens were taken out, total RNA was isolated, and levels were analyzed using Affymetrix GeneChip. Higher mRNA levels of connexin 43(More)
Albino and pigmented guinea pigs were compared in terms of susceptibility to acoustic trauma. The animals were exposed to a 4 kHz pure tone of 120 dB for 60 min. N1 thresholds of CAP were measured before and after the acoustic exposure. Changes in the outer hair cell and stria vascularis were studied using SEM and TEM. After acoustic trauma, N1 thresholds(More)
