The morphologic changes of the closed injured brain of rats were observed by SEM. The rats either died immediately after conclusive injuries or were killed after 5 minutes to 5 days after injuries. The main changes were as follows: the diffuse disorder, twist, wave-like distortion and break of neuron fibers; axonal swelling; formation of axonal retraction balls; stripping and denotation of myelin sheath The ball-like swelling of neuron, break of neuron membrane and vascular wall, and microthrombus formations were also observed. These damages worsened with prolongation of surviving time of the rats. The axonal retraction ball appeared 8 hours after the injury and was approximately 3-5 cm in diameter, and developed to 7-8 cm after 3-5 days. It is observed that frontal lobe, cerebellum and brain stem were severely damaged. 相似文献

Previous research has identified Emotional Separation and Personal Control as two sets of home leaving indicators that are associated, respectively with relatively troubled and relatively untroubled parent-adolescent separation. As expected, among late adolescent males, parental divorce was highly related to endorsement of Emotional Separation as an important composite indicator of having left home. For females, being a firstborn was associated with endorsing Personal Control as an important composite indicator of home-leaving. Findings were interpreted as supporting previous research which has indicated that males experience more adjustment problems after parental divorce than females.Received Ph.D. from Michigan State University. Current research interests are parent-adolescent separation and perceptions of loneliness.Received Ph.D. from Michigan State University. Current research interests are adolescent-parent separation and evaluation research. 相似文献

Hypotheses are tested concerning the relationship between level of and changes in self-attitudes on the one hand and the adoption of membership in the charismatic religious movement on the other hand. The hypotheses are derived from a general theory of deviant behavior. Subjects (generally aged 13–25) were 65 members of a local charismatic religious group and a comparison group of 47 members of three, more traditional urban Protestant churches. Self-attitudes were measured by a self-derogation scale responded to with reference to two points in time: the present and 6 months to 1 year prior to the test administration. The three hypotheses were supported. (1) The charismatic subjects, relative to the comparison subjects, displayed significantly higher levels of self-derogation at the time of adopting membership in the charismatic group. (2) Individuals who adopted membership in the charismatic cults, relative to the comparison group, displayed a significantly greater tendency to decrease the level of self-derogation between the earlier point in time and the point in time when the subjects were interviewed. (3) Significantly greater decrease in self-derogation on the part of the charismatic cult subjects resulted in comparable levels of selfderogation for the charismatic and comparison groups at the time of the interview.Received M.D. from the University of Ottawa in 1960, did his fellowship in psychiatry in Mayo Clinic, 1968–1970, and is a fellow of the American Board of Neurology and Psychiatry (1973). Major interest is religion and psychiatry.Received Ph.D. in sociology from New York University in 1958. Current research interests are social psychiatry and, more specifically, the reciprocal relationship berween self-attitudes and the adoption of deviant response patterns. 相似文献

Middle-class adolescent boys and girls with strong attitudes for and against the sex-role ideology of the Women's Movement were administered a Q-sort to study two aspects believed to be related to identity formation: flexibility-rigidity and independence-dependence. A significant positive relationship was found, more strongly for independence than for flexibility and more strongly for girls than for boys. More favorable attitudes toward sex-role equalitarianism were associated with flexibility and independence. The strength of the associations varied with the nature of the Q-sort: ideal self, self as ideal member of opposite sex, and self as ideal to each parent.This article is based on the dissertation by Dr. Kirsch in partial fulfillment of the Doctor of Philosophy Degree at the Graduate School of Education, University of Marylandm, College Park, MarylandPsychotherapist in private practice in Potomac, Maryland, with special interest in psychology of women.

Before they reunified, the two Germanies provided a natural experiment in whether law could rectify what many have seen as injustice between men and women in the household. East German legislation mandated that equal hours of housework be contributed by husband and wife, while West Germany allowed the couple to reach any arrangement they chose. This paper explores the predicted and actual consequence of the two regimes for labor force participation, divorce, and equality within marriages. 相似文献

A 53-year-old woman who was diagnosed as suffering from depression was found dead in her bed. The autopsy revealed no morphological changes sufficient to explain death. Toxicological analysis was performed and the drugs trimipramine (2.33 mg/l), citalopram (4.81 mg/l) and zolpidem (0.07 mg/l) were identified in the femoral blood. A combined drug intoxication resulting in synergistic effects to cardiovascular disorders was proposed as the cause of death. An acute overdose and suicide was suggested by calculation of the parent drug to main metabolite ratios in femoral blood and liver tissue. The trimipramine to desmethyltrimipramine ratios were calculated to be 2.06 and 3.18, the citalopram to desmethylcitalopram ratios were 1.96 and 2.02. 相似文献
