The Effects of Carbon Dioxide Pneumoperitoneum on Tyrosine Hydroxylase Activity

Abstract

These results indicate that CO2 pneumoperitoneum applied with 10 and 15 mm Hg pressure gradually decreases the adrenal medulla TH activity; TH is an indispensable enzyme for the biosynthesis of catecholamines. CO2 pneumoperitoneum with 15 mm Hg pressure significantly elevated hypothalamus TH activity.
