A Reseach for biorhythm in school refusals

作为一个宪法predisposition的schoolsals，我们调查给予特别强调他们的生物节律。检查项目包括：整夜睡眠脑电图、深体温、血清皮质醇（Cor）、<beta>血清内啡肽（<beta>-Ep）、尿量、尿钠排泄量、尿儿茶酚胺（CA）、皮肤电位和心率，受试者为63例拒学者，但检查项目各不相同，并包括部分临床症状不明的儿童。根据DSM-（第<III>3版精神障碍诊断与统计手册<III>）对被试进行了分类，并探讨了被试的类别与测验结果的关系。（1）在血<beta>-Ep、尿钠排泄、皮肤电位和心率等项目中，无内在昼夜节律者（24+！-&gt; 4小时循环）我们 关于我们 拒绝入学组的r显著大于对照组。(2)As在整夜睡眠脑电图中，拒学者多表现为睡眠效率指数和REM睡眠下降或入睡后觉醒次数增多等睡眠模式异常，但在DSM-1型之间无明显趋势<III>。（3）腹部和足底深部体温的测定结果表明，拒学者和不明临床症状组的腹部和足底温度差减小，足底温度的节律性变化也减少。（4）采用多变量分析方法，对尿CA排泄节律与适应功能（DSM-，轴5）水平之间的相关性<III>进行了研究。结果表明，CA排泄量的某些变量与适应功能水平之间存在显著相关性，说明可以通过与生物节律有关的各种参数来识别拒学行为的异常。少

As a constitutional predisposiotion of school refursals we investigated giving a special emphasis on their biorhythm. The checking items were as follows : all night sleep EEG, deep body temperature, serum cortisol (Cor), serum <beta> -endorphin ( <beta> -Ep), urine volume, urinary sodium excretion, urinary catecholamines (CA), skin potential level and heart rate.The test subjects were 63 cases of school refusals but checking items were somewhat different with one another and,in addition,partially,children who showed only unidentified clinical syndome were included. Further, the school refusals were classified according to DSM- <III> (Diagnostic and Statistical Mannualfor Mental Disorders, <III> rd Edition) and relationships between the classes and the test.results were investigated.(1)With respect to items of blood <beta> -Ep, urinary sodium excretion, skin potential level and heart rate, the number of subjects who did not show the intrinsic circadian rhythm (24 <+!-> 4 hours cycle) we … More re significantly larger in the group of school refusals than the control group.(2)As to the all night sleep EEG, the decrease of sleep efficiency index and REM sleep or increase of waking after sleep onset or such that indicated the abnormality of sleep pattern were observed many in the school refusals, however, no discernoble tendency among the types of DSM- <III> was noted.(3)The results of deep body temperatures in abdominal and plantar regions indicated that in the school refusals and unidentified clinical syndome groups, decrease of the difference between abdominal and plantar temperatures as well as decrease of rhythmical change of plantar temperature usually observed in normal subjects were noted.(4)Correlations between variables derived from the excretion rhythm of urinary CAs and the levels of adaptive functioning (DSM- <III> , Axis 5) were investigated by means of multivariate analysis. The results showed significant correlations between some variables of CA excretion and the level of adaptative functioning.From the above results, it was elucidated that the abnormality of school refusals can be identified by various parameters related to biorhythm.
