Nutrition, health and psychosocial profile of institutionalized children.

A study was undertaken to assess the health, nutrition and psychosocial profile of Institutionalized children in four States--Uttar Pradesh, Andhra Pradesh, Karnataka and West Bengal. A sample of 3,822 children from 70 institutions in 6-18 years age group formed the subjects of the study. It was observed that the destitute children were mainly taken care of in three types of institutions, viz, Voluntary, Government Aided and Government run institutions. Calorie deficiency and deficiency of Vitamins and minerals characterized the diets of these children. In general, there was no deficit of protein in their diets. Growth wise, these children were retarded both in height and weight compared to standards. However, they fared better in comparison to their age and sex counterparts in the rural and urban poor. Psychosocial profile of these children indicated that the prevailing environment in the institutions is less conducive for intellectual stimulation but not so for the development of skills of self-help, locomotion, socialization and imagery.     

Immunomodulatory Effects of γ-HCH (Lindane) in Mice

Mice were fed for 24 weeks with three different subtoxic dosages of γ-HCH (0.012, 0.12 and 1.2 mg/kg) mixed in powdered feed. The immunological profile was assessed at an interval of one month during the entire exposure period. Both the cell mediated and humoral components of immunity showed a biphasic response characterized initially by stimulation followed by suppression in a dose dependent manner. However, γ-HCH did not affect the functional properties of peritoneal macrophages. Histological changes in lymphoid organs were in accordance with the biphasic immunomodulatory effects of γ -HCH.     

Pathophysiologie, évaluation et traitement médical de l’incontinence fécale

L’incontinence fécale est un problème fréquent en pratique médicale mais souvent sous-estimé et mal traité. Cet artiele revoit l’épidémiologie, les mécanismes pathophysiologiques et les approaches diagnostiques des patients souffrant d’incontinence fécale. De plus, je ferai une synthèse des traitements médicaux de l’incontinence fécale. Une anamnèse systématique et une étude de la morphologie et de la physiologie anorectales permet souvent de mettre en évidence les mécanismes pathogéniques sous-jacents et d’orienter le traitement.     

Chronic ethanol intake may delay the onset of gossypol-induced infertility in the male rat

Summary. Parameters were obtained from the reproductive organs of ethanol-fed, gossypol-treated Sprague Dawley rats. The experimental animals were fed either on a normal (15.17%) or low protein (8.00%) diet. Measurements included reproductive organ weights, seminal characteristics, serum concentration of testosterone and histological, stereological and histomorphometric evaluation of the testis. The testis size, length and diameter of the seminiferous tubule had the least values in the protein-malnourished, gossy-pol-treated rats (3.01±0.26 g, 0.56 ± 0.03 m, 281.34±11.30 μn), in comparison to corresponding animals which had received ethanol simultaneously with gossypol (3.40 ± 0.25, 0.71±0.06m, 314.42 ± 11.61 μn). As gossypol and ethanol are both associated with reduced reproductive capacity, this unexpected but interesting finding lends support to the hypothesis that either a normal dietary protein or ethanol consumption may modify the action of gossypol on body tissues, including the testis. This effect, presumably mediated through changes caused to the bioavailability of gossypol, modifies its antifertility activity. The present observation further highlights the need to consider the concurrent administration of other drugs, such as alcohol, and the nutritional status in the evaluation of gossypol for various potential uses.     

Inhibition of spontaneous testicular Leydig cell tumor development in F-344 rats by dehydroepiandrosterone.

The incidence of spontaneous Leydig cell tumors of testis is very high in old F-344 rats. We have examined the effect of dehydroepiandrosterone (DHEA), a steroid hormone with antimitotic and anticarcinogenic properties, on spontaneous Leydig cell tumorigenesis. Fifteen-week-old male F-344 rats were fed a diet containing DHEA (0.45% w/w) for 84 weeks. At the termination of experiment none of the 13 rats had Leydig cell hyperplasia or Leydig cell tumors. All the eight control rats of comparable age had Leydig cell tumors. These findings suggest that DHEA is a potent inhibitor of spontaneous Leydig cell tumors of testis in aged rats.     

Dengue fever presenting with acute colitis.

Gastrointestinal manifestations of dengue fever are mainly in the form of bleeding or liver function abnormalities. Dengue fever presenting as acute colitis-like picture is not reported to date. We report a 50-year-old man with dengue fever presenting with lower gastrointestinal bleeding and colonoscopic features of acute inflammatory colitis.
