Jean-Philippe Gueguen 《L'évolution Psychiatrique》2003,68(1):17-26
In 1967, some hematologists who were inspired by Barbey d’Aurevilly’s novel, “A story without a name”, described the syndrome of Lasthénie de Ferjol: recurrent anemia resulting from voluntarily provoked hemorrhages. We used the same novel as a basis for studying the mother-daughter relationship. Madame de Ferjol is widowed, and lives a reclusive life with her only daughter, Lasthénie, until such time as a capuchin priest enters their life during Lent. This unexpected encounter with sexuality (Lasthénie becomes pregnant) has a marked effect upon the young woman; she withdraws into total silence, and displays self-mutilating behavior (provoked bouts of anemia) which leads to her death and to that of her unborn child. In this tale, we see a paradigm of the mother-child relationship that has already been observed in anorexia nervosa. Mother and daughter are caught up in a narcissistic dyad fom which neither is able to extricate herself. The mother remains in a pathological state of mourning, and we put forward the hypothesis that this dead mother is affected by a melancholic process in which her hatred is projected onto her daughter. Finally, we have attempted to examine the connections between hysteria and anorexia nervosa, as in this story rivalry between mother and daughter also plays a role, and in which sexuality—therefore involving a third party—is unmentionable. 相似文献

Der Einfluß des Druckes in den Coronararterien auf die Druck-Volumen-Beziehung des linken Ventrikels
Ph. Greuner-Sigusch G. Greuner C. Morgenstern 《Pflügers Archiv : European journal of physiology》1973,338(3):233-246
Summary The influence of coronary perfusion pressure on the pressure-volume relation of the left ventricle was investigated in isolated and arrested cat and dog hearts. The left coronary artery was separately perfused.The duration of the experiment, edema of the myocardium and the inflow through the Thebesian vessels complicate the measurement of the pressure-volume relation.Excluding these factors the experiments prove, that coronary perfusion pressure is a determinant of the pressure-volume relation of the heart. Increasing coronary pressure shifts the relation between pressure and volume upward and to the left (Figs. 3 and 4).
increases with increasing coronary perfusion pressure, while the elasticity modulus
is not changed (Fig. 5). 相似文献

Summary Concentration dependence of strontium (Sr) fluxes across the colon ascendens and descendens of the rat were measured in a modified Ussing-chamber. Mucosa (m) to serosa (s) and s to m Sr fluxes across both colonic segments were linearly related to the Sr concentration from 0.125 mmol/l to 10 mmol/l. In the colon ascendens m to s Sr fluxes were slightly higher than the fluxes in the opposite direction, resulting in net Sr absorption. In the colon descendens s to m fluxes were higher than the ms fluxes, resulting in net Sr secretion. Neither Sr nor calcium (Ca) showed a concentration dependent interaction with respect to their unidirectional fluxes in both parts of the colon. Only in the colon ascendens Sr at the highest concentration (10 mmol/l) inhibited m to s calcium transport.Experiments, in which the voltage dependence of the unidirectional Sr fluxes was measured confirmed the results obtained from the concentration dependence: (1) The unidirectional fluxes of Sr across the colon ascendens and descendens were totally voltage dependent, i.e. diffusive. (2) In the colon descendens the voltage dependence of the s to m flux was steeper than the flux from m to s. It is hypothesized that this prevalence is caused by an anomalous solvent drag effect. 1.25-Dihydroxyvitamin D3 [1.25 (OH)2D3] stimulated m to s calcium flux in the colon descendens but had no effect on Sr flux.The results demonstrate that Sr and Ca in the rat colon are transported by different mechanisms. In contrast to the Ca transport the Sr flux is only diffusive and insensitive to 1.25 (OH)2D3.Supported by the Deutsche Forschungsgemeinschaft SFB 38 Membranforschung

酒中毒患者戒酒相关因素的分析 总被引:7,自引:0,他引:7
目的:探讨酒中毒患者维持戒酒状态的相关因素。方法:30例住院的酒中毒病人(饮酒组)和13例出院以后戒酒二年以上的酒中毒病人(戒酒组)以明尼苏达多项个性调查表(MMPI),汉密顿抑郁量表(HAMD),汉密顿焦虑量表(HAMA),以及有关酒中毒认识方面自编问卷,并调查入院记录及出院以后采取措施等进行对照研究。结果:饮酒组MMPI量表中L、Hs、D、Hy、Pt分高于戒酒组,Pd分饮酒组高于戒酒组,并出现1,2,4,6测图,HAMD,HAMA量表饮酒组高于戒酒组,说明有明显的躯体不适感和抑郁焦虑,强迫症特征和人格障碍特征,戒酒组对酒中毒认识分高于饮酒组,主动住院和出院以后坚持戒酒康复活动(简称AA活动),戒酒组多高于饮酒组。结论:对酒中毒认识程度越深刻,戒酒效果越好,出院以后坚持AA活动是成功戒酒的有效措施。 相似文献

从针刺不同经穴对家兔胃黏膜保护作用探讨多经司控同一脏腑的规律 总被引:13,自引:2,他引:13
目的:探讨经脉腧穴与脏腑的特异关系.方法:将56只家兔随机分为7组,分别针刺不同经的穴位.硝酸还原酶法测定胃黏膜NO和NOS含量,放射免疫法测定PGE2、EGF含量,加权法分析各组综合效应.结果:(1)针刺足阳明经组与其余各组比较,能显著升高胃黏膜PGE2、EGF含量(P<0.01);(2)针刺足阳明、足太阴经组与其余各组比较,能显著升高胃黏膜NO和NOS含量(P<0.01);(3)针刺足阳明经组综合效应明显高于其余各组(P<0.01);针刺足太阴经组综合效应明显高于模型组(P<0.01).结论:多经司控同一脏腑具有一定的普遍性,但从作用强度和广度看又具有经脉的相对特异性;胃与足阳明经关系最为密切,足太阴经次之. 相似文献
