Objective: To investigate the high risk factors of occurring the syndrome of cerebral-internal organs in the patients with acute cerebral hemorrhage(ACH).Methods: The serum concentrations of follicle-stimulating hormone(FSH),thyroid-stimulating hormone(TSH) and adrenocorticotrophic hormone(ACTH) were measured by electrochemical radiation in acute period of 37 cases with ACH and 24 cases with cerebral infarction,and compared to those of the 30 healthy controls.The correlations among levels of serum FSH,TSH,ACTH and condition of illness,amount of hemorrhage,critical chamber hemorrhage and the displacement of cerebral mid-line structures were observed.Results: The levels of FSH and TSH were significantly lower,and the levels of ACTH were obviously higher in cases with ACH and cerebral infarction than those of healthy volunteers,and their changes in levels were more obvious in patients with ACH than in patients with cerebral infarction (all P
