[A surgical emergency: iatrogenic lesion of the spleen. Case report and review of the literature]. / Un'emergenza chirurgica: la lesione iatrogena della milza. Caso clinico e review della letteratura.

The spleen is an organ often injured during surgical procedures. Iatrogenic lesions belong frequently to a low grade and can be treated with a conservative therapy. The surgeon may avoid the splenectomy by using new haemostatic agents as the patch of fibrinogen and thrombin in fixed combination.

The effect of caloric supplementation on selected milk protective factors in undernourished Guatemalan mothers.

The level and avidity indices of specific antibodies against tetanus toxoid, Escherichia coli O6 and a pool of 10 common E. coli O antigens, as well as the concentration and daily output of lactoferrin and total secretory IgA (SIgA), were evaluated in the milk of moderately undernourished mothers who were in a random blind design divided into two groups and given different caloric supplementations. Group A received a high caloric supplement (500 kcal/d), and group B received a low caloric supplement (140 kcal/d). Determinations were done using ELISA in various modifications, except for lactoferrin, which was quantified by single radial immunodiffusion. The avidity indices were investigated as an evaluation of the antibody quality. In all the parameters evaluated, the only difference found between the two groups at the end of the supplementation period was in the content of total SIgA, which was lower in group B, both in concentration and daily output. However, the SIgA remained within the normal range. Increases as well as decreases in the levels of specific IgA antibodies occurred within both groups. Avidity was decreased in group B only against one of the antigens tested. We conclude that moderate undernutrition does not impair the levels of milk antibodies, and supplementation does not enhance them but prevents the decrease in the content of total milk SIgA. There is a suggestion that the avidity of certain antibody specificities could be hampered.

Pharmacologic properties of Moringa oleifera. 2: Screening for antispasmodic, antiinflammatory and diuretic activity.

Hot water infusions of flowers, leaves, roots, seeds and stalks or bark of Moringa oleifera were screened to detect three pharmacologic activities in experimental models in rats. The antispasmodic activity was demonstrated using isolated duodenum, oral anti-inflammatory activity by carrageenan-induced hindpaw edema and oral diuretic activity by urine output in metabolic cages. The seed infusion showed a significant inhibition of acetylcholine-induced contraction with an ED50 of 65.6 mg/ml bath concentration, inhibition of carrageenan-induced edema at 1000 mg/kg and diuretic activity at 1000 mg/kg. Some activity was also demonstrated in the roots. All doses expressed here are as equivalents of dried starting plant material.
