[Effects in rats of bee-wax alcohols (D-002) on ulcerative colitis induced by dextran sulfate and ethanol].

Objectives.: To investigate the effects of D-002, a mixture of 6 high molecular weight primary aliphatic alcohols, obtained from beeswax (Apis mellifera), on severe inflammatory ulcerative colitis (UC) induced by Dextran sulfate (DSS) and ethanol in rats (Ratus ratus).

[Gene expression of Interleukin 1 in vitamin A and proteins deficiency].

The influence of low levels of protein and vitamin A on indicators of the immune response was assayed in rats. The levels of protein and vitamin A intake of the Cuban population affected by epidemic neuropathy in 1993 was reproduced in 4 diets: control, protein deficiency (DP), vitamin A deficiency (DA), protein and vitamin A deficiency (DAP). The Peyer's patches evaluated the Interleukin 1 expression gene and was related with corporal weight, food intake, serum protein, vitamin A, immunology indicators and histology evaluation (spleen, thymus and liver).
