Leathery stomach is seen in poisoning with: BHU 09
**Core Concept**
The term "leathery stomach" refers to the characteristic appearance of the stomach mucosa in cases of certain toxic ingestions. This condition is a result of the toxic effects on the gastric mucosa, leading to its thickening and leathery texture.
**Why the Correct Answer is Right**
The correct answer is related to the toxic effects of a specific substance on the gastric mucosa. The substance in question causes the release of histamine, which leads to an increase in gastric acid production and subsequent mucosal edema. This results in the characteristic leathery appearance of the stomach mucosa. The relevant mechanism involves the activation of histamine receptors, specifically H2 receptors, which are responsible for the stimulation of gastric acid secretion.
