Corrections and Clarifications
In the report "Localization of targets for antiucler drugs in cells of the immune system" by E. Mezey et al. (4 Dec. 1992, p. 1662), on page 1662, in the second column, on the fourth line, the word "antagonists" was incorrect. The sentence should have read "Dopamine also modulates gastric acid secretion (4), and dopamine agonists prevent ulcer relapse (5)."
