[Retinylpalmitate-hydrolase activity of the intestine in experimental lambliasis].

The retinylpalmitate-hydrolase activity in the small intestine of healthy and lambliae infected rats was determined. Infection of rats with Giardia lambliae is shown to result in a fall of the retinylpalmiate-hydrase activity, which is restored, in part, on application of a specific therapy (0.1 g/kg of chinacrine) and then practically does not differ from that in healthy animals, when the specific therapy is employed in conjunction with an elevated dose of the vitamin "A" (2000 m.

[Vitamin A and carotin content in the blood of children with lambliasis-induced cholecystitis].

The blood vitamin A and carotene content in normal children and the ones suffering from Lambia-induced cholecystitis was studied. In the sick children examinations were made in dynamics before and after administration of antilambliasis drugs and vitamin A ingested in an oil solution. In patients with Lamblia-induced cholecystitis the vitamin A and carotene content was found to be down by comparison with controls, this pointing to a deranged vitamin A and carotene metabolism in the organism of such patients.
