暴力行为人群性激素水平的异常

Abnormal level of sex hormones in people with violent behaviors

目的 :探究暴力行为的生物学因素以及与其相关的性激素水平异常的原因 .方法 :男性暴力型服刑人员 4 6例为研究组 ,调查其个人史、进行体格检查 ,抽血检测去甲肾上腺素 (norepinephrine ,NE)、雌二醇 (estradiol,E2 )、睾酮 (testos terone,T)和一氧化氮 (nitricoxide ,NO)等 ;选择无暴力行为的男性健康公民 2 3例为对照组 .结果 :研究组全部属A型行为类型 ;87.0 %交感神经功能亢进 ;6 7.4 %NE增高 ;6 1.0 %E2 增高 ;6 7.4 %T降低 ;91.3%NO降低 ,与对照组之间差别有显著性意义 (P <0 .0 5 ,P <0 .0 1) .结论 :A型行为通过兴奋交感神经使NE增高 ;NE增高是暴力行为的生物学因素 ;E2 增高是机体对A型行为及NE增高所造成的精神损伤产生心理保护性反应的结果 ;机体是通过降低NO和T使E2

AIM: To study the causes of the abnormal level of sex hormones in people who have violent behaviors and the biological factors of violent behaviors. METHODS: The experimental group consisted of 46 male prisoners who had severely violent behaviors and whose personal histories were investigated and physical examination and blood test were conducted to detect the correlated hormones. The control group consisted of 23 healthy males. RESULTS: All the 46 cases in the experimental group fell into the type A behavior and 87.0% of them had sympathetic hyperfunction. 67.4% and 61.0% of them were found to have increased NE and E 2 respectively and 67.4% and 91.3% of them were found having to have decreased T and NO respectively. There was significant difference between the experimental group and the control group ( P <0.05, P < 0.01 ). CONCLUSIONS: The increase of NE is the biological factor in type A with violent behavior, which results from the exciting sympathetic nerves. The increase of E 2 is the psychological protective reaction of a body against the psyche impairment resulting from type A behavior and NE increasing. The increase of E 2 comes from the decrease of NO and T.
