The effect of vitamin D3 in the composition of original rectal suppositories on the content of products of oxidative modification of proteins in mucous membrane of the large intestine was studied in rats with experimental ulcerative colitis provoked by a two-stage administration of 3% oxazolone. The rectal suppositories with vitamin D3 (1500 IU) were administered every 12 h during 5 days. Condition of the rats was assessed according to disease activity index (DAI), while the content of oxidative modification products of proteins in the homogenate of the mucous membrane was assayed with extraction-spectrophotometric method in the lesion focus of large intestine. DAI increased during entire observation period of ulcerative colitis, which correlated with the level of products of spontaneous and induced oxidative modification of proteins in mucous membrane of the colon. The study examined the pharmaceutical and technological features of novel rectal suppositories of original composition weighing 300 mg, which are based on polyethylene glycol supplemented with aqueous solution of vitamin D3 (10%). The use of rectal suppositories with vitamin D3 reduced DAI and inhibited the oxidative modification of proteins. |
