Hyperaemia in rat neocortex produced by acute exposure to methylenedioxymethamphetamine

Cerebral blood flow and glucose utilization were measured in rat neocortex, hippocampus and striatum following methylenedioxymethamphetamine injection (5 mg/kg, i.v.), using the tracers [¹⁴C]iodoantipyrine and [¹⁴C]2-deoxyglucose, respectively. In control rats, blood flow was coupled to glucose metabolism, but in methylenedioxymethamphetamine-treated rats, marked hyperperfusion was measured in frontal and parietal cortex with no change in glucose use. This suggests that methylenedioxymethamphetamine has the potential to disrupt cerebrovascular control.     

Insults to the body civil: Mistreatment of elderly in two Plains Indian tribes

The mistreatment of elderly is subject to various social constructions. On two geographically distinct Plains Indian Reservations which we call Lone Mountain and Abundant Lands, the abuse or neglect of elderly is construed as a health problem which is a dysfunction of the community as a whole. Both physical abuse and neglect are more common on the Lone Mountain Reservation, occurring in association with other indicators of community disorganization such as unemployment and substance abuse. On the Abundant Lands Reservation physical abuse was categorically denied and what neglect existed appeared to be a function of role strain, geographic dispersal, climate and terrain. We attribute differences in the prevalence of mistreatment of elders to variations in economic opportunities for younger residents. Examining the historical and present contexts of intergenerational relationships on the reservations, we discuss the implications of this study for social exchange theory and policy applications.This research was supported by the Gerontological Society of America AppliedThis research was supported by the Gerontological Society of America AppliedThis research was supported by the Gerontological Society of America AppliedThis research was supported by the Gerontological Society of America AppliedThis research was supported by the Gerontological Society of America AppliedThis research was supported by the Gerontological Society of America Applied     

Early separation and suicidal behaviour in the parental homes of 40 consecutive suicide attempters

Forty suicide-attempt patients who were consecutively admitted to an intensive-care unit, their significant others and treatment personnel were investigated by semistructured interviews. The patients were divided into neurosis (n = 14), abuse (n = 19) and psychosis (n = 7) groups. Twenty-one of the patients (52%) had lost contact with one or both parents before the age of 18, in 25% of cases owing to death and in 27% because of the parents' divorce or separation. Parents and/or siblings of 19 patients (47%) had shown suicidal behaviour in the form of attempted suicide and/or suicide. Differences between the groups were not significant. Alcohol abuse in the parental home was overrepresented in the abuse group compared with the other groups. The role of identification with the dead and suicidal parent in prompting suicidal actions in adulthood is discussed, as well as that of the impeded evolution of stable external object relations owing to parental losses.

精神分裂症患者心理防御机制与人格特征的相关性分析

目的　探讨精神分裂症患者心理防御方式和人格特片的特点及二者的相关性。方法　分别运用防御方式问卷 (DSQ)和艾森克个性问卷 (EPQ)对 10 1名精神分裂症患者和 30例正常人群进行防御方式评定和人格测定。结果　与正常对照组相比 ,精神分裂症患者更多采用不成熟和中间型防御方式 (P <0 0 5 )。防御方式与人格特征存在着一定的关联性 (P <0 0 5 )。不成熟型防御方式和中间型防御机制与EPQ的精神质 (P)得分和神经质 (N)得分呈显著正相关 (P <0 0 1) ,成熟防御机制与内外向(E)得分呈显著正相关 (P <0 0 5 )。结论　精神分裂症患者更多地使用不成熟防御机制 ,存在病态人格 ,且者之间存在明显相关性 ,有关结果 ,对于探讨精神分裂症患者的病理心理机制和开展心理治疗有指导意义。     

海洛因依赖者的个性心理特征及其对复吸的影响分析

目的了解自愿戒毒的海洛因依赖者的个性心理特征及其对脱毒后复吸的影响。方法使用MMPI对30例自愿戒毒的海洛因依赖者和30例未对任何药物成瘾的正常人的个性心理特征进行对照分析，明确海洛因依赖者个性心理特征，在此基础上找出个性心理特征与复吸原因的联系。结果海洛因依赖者在MMPI各量表中诈病(F)，精神病态(Pd)，疑病症(Hs)，偏执狂(Pa)，精神分裂(Sc)等量袁与对照组有明显的差异，且这些差异与脱毒者复吸原因有着直接的关系。结论海洛因依赖者的个性心理特征为明显的反社会行为和社会适应障碍，对自己健康过分关注，缺乏对社会环境的归属感，易将自己的问题合理化而归因于剐人，并由这种心理特征增加了复吸率。     

心理支持疗法对机械通气患者应激反应的影响

目的 观察心理支持疗法(PST)对ICU患者机械通气应激反应的影响。方法 将34例连续机械通气时间在20h的清醒患者，随机分为采用标准的PST方法进行治疗的观察组和对照组，观察焦虑抑郁程度和应激反应改变情况。结果 对照组患者的焦虑抑郁程度明显高于观察组，部分应激反应激素水平升高幅度也明显大于观察组。结论 PST可通过缓解机械通气患者的焦虑抑郁等不良情绪状态减轻机械通气带来的各种心身应激反应，有利于提高机械通气治疗的有效性和安全性。

Aggression and substance abuse in bipolar disorder

Objectives:  The goal of this retrospective study was to examine factors differentiating persons with bipolar disorder who did or did not have comorbid lifetime substance use disorders (SUD) at an index assessment. We also explored the chronology of onset of mood and SUD.
Methods:  We studied 146 subjects with DSM-defined bipolar disorder. Subgroups with and without lifetime SUD were compared on demographic and clinical measures.
Results:  Substance abuse disorders in this bipolar sample were associated with male sex, impulsive-aggressive traits, comorbid conduct and Cluster B personality disorders, number of suicide attempts and earlier age at onset of a first mood episode. In a multivariable logistic regression analysis, male sex and aggression and possibly earlier age at mood disorder onset were associated with SUD. In those with or without SUD, the first mood episode tended to be depressive and to precede the onset of SUD.
Conclusions:  In persons with bipolar disorder, an earlier age of onset and aggressive traits appear to be factors associated with later development of comorbid SUD.
