[Prevention of stress ulcer by vitamin A. Experimental study in rats].
71 male rats (Whitstar strain) are submitted to restraint. 37 of them were receiving twice an injection of 10 000 I.U. of vitamin A in order to protect them against the occurence of stress ulcer. Untreated animals are used as controls. Incidence of obtained ulcer is compared with the variation of vitamin A serum concentration, classicaly decreased in stress. Analysis of individual results shows that, if parenteral administration was followed either by restitution of the initial serum concentration, or by its increase, the treatment was efficient in 64 p. 100 of the cases.
