Abstract

The input of parasympathetic region of vegetative nervous system in regulation of regional blood transfer and maintaining of oxygen balance in organs of rat digestive system has been estimated by measuring oxygen tension (pO2) and the rate of regional blood transfer (RBTR) in liver, gut, and small intestine after 1, 7, 14, 30, and 60 days after vagotomy. Vagotomy was shown to lead to the decrease of pO2 in liver (1, 14, 30 days), gut (1 day), and small intestine (7 and 30 days). At initial postoperation period (1 day), the decrease in pO2 is accompanied by the increase in RBTR (in gut and small intestine), and at late period, by the decrease of RBTR in liver. The correlation between the decrease in pO2 and the decrease in RBTR allows to conclude that the hypoxia developing in liver after vagotomy is of a circulatory nature.
