Abstract
This work was done on 44 of stray dogs (males females) of different weights and different ages. They were divided into two main groups, the first, to study the normal gastro—intestinal tract with without contrast media, with special reference to the suitable time needed for contrast radiography of certain organs. The second group subdivided into two subgrcups subgroup 1, for experimental induction of some surgical affections of the
G.I.T. then application of x—ray for diagnosis of such affections using different radiographic views., different methods of animal control & preparation as fasting, application of tranquilizer (Combelen) in a dose of 0.2 mg/ Kg. E.wt. injected intramuscular and general anaesthetic (Nesdonal 57.) in a dose of 20 mg./ kg. bw. injected intravenous and priored by Combelen in a dose of 0.2 mg./ kg bw. injected intramuscular. Surgical affections were then treated surgically using different suture materials that were non—absorbable (prolene ‘ mersiline) and absorbable ones (plain, chromic catgut and dexon) and study their effect on the tissues to evaluate which one(s) ‘is better after visual and histopathological examination for samples obtained j after euthanasia. The subgroup 11, used to conduct somt experimental surgical studies on the esophagus (exposure and esophaqotomy using longitudinal incisions then closed by longitudinal transverse closure), on the stomach (gastr-ectomv
of different segments)1 and on the intestine (resection for 0.5
