Effect of peptic digestion on emptying of cooked liver in dogs.

abstract：:Previous investigations demonstrated that S-adenosyl-L-methionine suppresses the cholestatic effect of ethynylestradiol and reduces the irreversible binding of the estrogen to rat liver microsomes, probably favoring ethynylestradiol transformation into its methyl-derivatives. Since it is not known whether SAMe also pr...
