目的　观察脑出血患者血清甲状腺激素水平变化 ,探讨其发生机制及临床意义。方法　应用放免法测定脑出血组 (急性期与恢复期 )和对照组T3 、T4、TSH含量。结果　急性期脑出血病人较对照组T3 明显减低 ,T4、TSH明显升高 ,差异有显著性 (P <0 0 1)。各项指标随病情好转而恢复。结论　脑出血患者急性期T3 、T4、TSH均有显著改变 ,且是可逆的。 Objective To observe the changes of serum thyroid hormones in patients with intracerebral hemorrhage and to explore its mechanism and clinical significance. Methods The levels of T3, T4 and TSH in cerebral hemorrhage (acute and convalescent) and control groups were determined by radioimmunoassay. Results Acute cerebral hemorrhage patients than in the control group T3 decreased significantly, T4, TSH was significantly higher, the difference was significant (P <0.01). The indicators recovered with the condition improved. Conclusion The acute phase of cerebral hemorrhage patients T3, T4, TSH were significantly changed, and is reversible.
