adrenergic receptors and sensitization of adenylyl cyclase in acute myocardial ischemia.acute myocardial ischemia leads to a gradual increase in beta-adrenergic receptors at the cell surface. this increase occurs rapidly after onset of global ischemia (15 minutes) and persists even after prolonged periods of global ischemia. this alteration can be observed both in vivo and in vitro in isolated perfused hearts. several groups have previously shown that ischemia induces a local release of endogenous catecholamines. here, we show that these endogenous catecholamines are sufficiently h ...20072168300
in vitro cytotoxic effects of cobalt-containing dusts on mouse peritoneal and rat alveolar macrophages."hard metal disease" is a chronic lung disease characterized by the presence of interstitial fibrosis; the role of cobalt in the development of this entity is still debated. indeed, most cases have been observed in some workplaces (grinding) of the hard metal industry and in the diamond polishing industry whereas no similar cases have been reported from workers exposed to pure cobalt powders in cobalt refineries. this study was designed to assess the in vitro toxicity (ldh release, morphology) o ...19902168316
