Recent neuroanatomical and behavioral evidence has indicated that vasopressin (VA) increases pain threshold. The dorsal raphe nucleus (DRN) is an important nucleus in pain modulation. Anatomical studies have shown that DRN receives vasopressinergic fibers originating in the hypothalamic paraventricular nucleus. The aim of the present study was to examine the effects of intra-DRN injection of de...

Syndrome de la queue de cheval. A propos de 4 cas.  Les auteurs rapportent quatre observations cliniques concernat des malades dont les pre­miers symptomes se manifesterent par des al­gies longitemps considerees comme "sciatique·s".  L' etude neurologique de ces cas demontrait qu'en realite "les algies sciatiques" n'etaient que des signes mono ou pluri-radiculaires en rapport avec un syndrome...

Recent studies have shown that diethylstilbestrol (DES) induces sister chromatid exchanges (SCEs) in lymphocytes from pregnant and premenopausal women but has only a slight effect on lymphocytes from postmenopausal women or men. In this study blood specimens from premenopausal women were used to define the role of different metabolic pathways on DES-induced formation of SCEs and to determine wh...
