Effects of the menstrual cycle of white women on ethanol toxicokinetics.

Objective: The aim of this study was to investigate the existing variations of the kinetics of ethanol in white women during the menstrual and luteal phases to further current understanding of the role of the menstrual cycle in gender differences in ethanol's adverse effects.

Method: In a within-subjects design, 10 female white volunteers were administered a moderate dose of ethanol (0.3 g/kg) in the morning after an overnight fast.

Anti-inflammatory activity and gastric lesions induced by zinc-tenoxicam.

Oral administration of tenoxicam or zinc-tenoxicam complex inhibited to a similar extent carrageenin-induced paw oedema and granulomatous tissue formation in rats as well as the acetic acid induced writhing response in mice. Gastric lesions induced by oral administration of zinc-tenoxicam were reduced in number and severity when compared with those induced by tenoxicam or the co-administration of tenoxicam and zinc acetate. However, after intraperitoneal administration, both zinc-tenoxicam and tenoxicam plus zinc acetate induced a reduced number of gastric lesions as compared with tenoxicam.
