بررسي اثر هورمون ADH بر بسته شدن ناودان مري اي در گوسفند جهت درمان بيماريهاي داخلي و مقايسه آن با روش هاي سنتي

Investigation on the effect of ADH on the oesophageal groove closure in sheep for treatment of internal diseases and compare with previous methods

In this research , we had tried to produce the oesophageal groove closure reflex by injecting ADH hormone of the posterior hypophysis and follow the procedure by radiography. The following experiments had been performed : 1)Plain radiography of 5 sheep. 2) Radiography of the oesophageal groove area with barium sulfate without hormone injection. 3)Radiography of the oesophageal groove area with Barium sulfate after I.V injection of 0.5 lU/Kg of Lysine Vasopressine hormon. 4) Radiography of the oesophageal groove area with Barium sulfate after I.V injection of 1 IU/Kg of Hormone. 5)Fistulation of Rumen and abomasal fistula and abservation of the coloured material Pretruding through the fistula before and after I. V injection of the hormone. 6) Radiographic study of the groove area with barium sulfate after cupper sulfate consumption by the animal. 7)Radiographic study of the groove area after lntra-arterial injection of 1.5 ml hypertonic NaCl solution. 8)Radiographic study of the groove area with Barium sulfate after 48 hours of water deprivation. The results showed that except water deprivation non of the aformentioned experiments oesophageal groove refllex had been Produced and with considering the ADH effects on closure of the groove in cattle there might be some physiological differences existing between cattle and sheep in this respect.
