Effect of Crataeva nurvala on the biochemistry of the small intestinal tract of normal and stone-forming rats.

Certain biochemical constituents were analysed in small intestinal tract tissues of rats fed a normal and a calculi-producing diet. Changes were seen in calculogenic rats with respect to the carbohydrate and sialic acid residues of glycoproteins along with some lipid fractions. Treatment with Crataeva nurvala bark decoction lowered levels of small intestinal (Na+,K+)-ATPases. The action of the decoction on the small intestinal tract seems to be mediated through (Na+,K+)-ATPases, which in turn may affect the transport of metabolites.
