Immunocytochemical detection of the 72-kDa heat shock protein in halothane--induced hepatotoxicity in rats.

abstract：:The patterns of prolactin release after bilateral ECT and after 0.4 mg TRH i.v. were studied in 11 female melancholic patients in a 5-min sampling protocol. Mean prolactin peaking times were 10.2 min after ECT and 20.5 min after TRH. The elimination rate coefficients were significantly lower--and the corresponding hal...
