Radiographic evaluation of rabbit gastro-intestinal tract with oral barium sulfate

The aim of this study was to use barium sulfate in rabbit gastro-intestinal (Gl) tract to detect transition time of different parts of (II tract, diameter of small and large intestines, side effects and compare them with lumbar vertebral and the width of the ribs in rabbits. In this survey, 30% suspension of barium sulfate was administrated orally to ten healthy rabbits with dosage of 12 ml/kg. No tranquilizer or anesthetic drugs was used. Radiography was performed in 0, 5, 10, 20, 40, 60, 80, 100, 120 minutes and every hour until stomach "vas completely emptied. Suspension of30% of barium sulfate produced satisfactory OI contrast radiographs. The stomach in 300/0 of the rabbits was emptied at 20 minutes after administration. The contrast media was observed in CeCUlTI after 40 minutes. There "vas more barium sulfate in the cecum in 60 minutes and in 120 minutes; it was fully distended with contrast media. Four hours later, the contrast media was seen in stool. ʹThere were contrast media in the stomach 4 hours, while it was completely emptied 5 hours after administration. We didn ʹt see any side effects after administration of barium sulfate in the rabbits. The width mean of small intestine was less than two times of the rib width mean and it was nearly equal to the height mean of L2. Also, the width mean of small intestine was less than 1.5 times of the height mean of L./S. Based on our results in this survey, barium sulfate can be used for evaluation of Gl tract in the affected rabbits in comparison with normal cases.
