“…Pharmacologic denervation of the parietal cell mass was suggested by previous research which employed the chemoneurolysis of peripheral and autonomic nerves. Thus, phenol [13,50], cobaltous chloride [8,15], and BAC [9,14,18,29,35,36,[39][40][41]46] are three agents that have been employed successfully both experimentally in animals and to a limited extent in man for denervation mainly for pain control. Due to the perceived chemoneurolytic nonspecificity and inferiority, phenol was not considered for further experimentation [49].…”
