Biochemical and histochemical studies revealed decreased beta-glucuronidase activity in the Brunner's glands of duodenal ulcerated rats. The enzyme activity showed gradual increase during recovery. Rats treated with a mixture of Ayurvedic medicines (Glycyrrhiza glabra, Terminalia chebula, Piper longum and Shanka Bhasma) recovered faster with concomitant increase in beta-glucuronidase activity in the Brunner's glands. It can be concluded that Ayurvedic medicines used do not act as antacid but improve the secretory status of Brunner's glands involved in the protection against duodenal ulcer.

The mucosal enzyme activities of 11 marker enzymes from the brush border, basolateral membrane, and lysosomes of 45 patients with an active duodenal ulcer (DU) were determined by analysis of homogenized biopsy specimens obtained from the duodenal bulb and descending duodenum at endoscopy. They were compared with activities measured in 22 controls. In the duodenal bulb lactase (p less than 0.005), neutral-alpha-glucosidase (p less than 0.0005), and monoamine oxidase (p less than 0.0005) were significantly decreased in DU patients. In the descending duodenum all the brush border enzymes except sucrase were significantly decreased when compared with controls. DU patients with inflammation in the biopsy specimens from the duodenal bulb had decreased levels of lactase (p less than 0.05), sucrase (p less than 0.05), neutral-alpha-glucosidase (p less than 0.05), leucyl-beta-naphthylamidase (p less than 0.05), and acid phosphatases (p less than 0.05) when compared with DU patients with normal histology in this region. In the descending duodenum the activities of leucyl-beta-naphthylamidase (p less than 0.05) were decreased in patients with inflammation compared with those without such histologic changes. DU patients who had taken antacids before the investigation had decreased activities of lactase (p less than 0.05) in the descending duodenum when compared with those who had not taken antacids. Activities of lactase (p less than 0.005), sucrase (p less than 0.005), neutral-alpha-glucosidase (p less than 0.05), and acid beta-glucuronidase (p less than 0.0005) in the descending duodenum were significantly lower in smokers than in non-smokers with active DU.

The activity of beta-glucuronidase was studied in the gastric aspirate from normal individuals, cases of duodenal ulcer with pyloric stenosis and carcinoma of the stomach. The optimum pH for the activity of this enzyme in the gastric aspirate is 4.0 to 5.5. Cimetidine, a H2-receptor antagonist, was administered orally to obtain the optimum pH for the enzyme activity, when the pH of the gastric aspirate was less than 4.0. It is observed that the enzyme activity in cases of carcinoma of the stomach is markedly elevated (p less than 0.01), when compared with other cases in this study. It is suggested that the elevated enzyme activity in the gastric aspirate could be used as a biochemical marker in the diagnosis of carcinoma of the stomach.
