Aging is associated with impairment of multiple organs, including skeletal muscle and heart. In this study, we investigated whether resveratrol, an activator NAD+-dependent protein deacetylase Sirtuin-1 (SIRT1), attenuates age-related sarcopenia cardiomyocyte hypertrophy in mice. Treatment mice resveratrol (0.4 g/kg diet) from 28 weeks age for 32 prevented aging-associated shortening rotarod riding time. the tibialis anterior (TA) muscle, histogram analysis showed that atrophic was increased...

We report a lethal case of mamushi (Gloydius blomhoffii) bite. An 84-year-old woman was bitten by snake on her right elbow. She initially treated at another hospital, however, because the swelling expanded and renal function worsened, she transferred to our hospital. Compartment syndrome, thrombocytopenia, respiratory arrest, elevated creatinine kinase lactose dehydrogenase levels were seen; failure progressed, ileus peritonitis due colon perforation occurred.The patient died 35 days after...

Early injection of anti-mamushi venom serum (antiserum) is believed to be effective for the treatment patients with mamushi bites. However, there no firm information that indicates time range constituting "early" injection. We tried quantify cut-off antiserum brings favorable clinical courses by clarifying relationship between and outcome.We retrospectively analyzed relationships after bite, antiserum, swelling grades, laboratory values.The in severe cases was significantly delayed as...
