Effect of cimetidine on 24-hour intragastric acidity in normal subjects.

The effect of H2-receptor blockade on intragastric acidity was studied in nine normal males. The pH of their gastric contents was measured at hourly daytime and two hourly nighttime intervals for 48 hours. The subjects ate identical meals, drank identical volumes of fluid, and smoked the same number of cigarettes during the two study days.

24-hour control of intragastric acidity by cimetidine in duodenal-ulcer patients.

The effects of two dose regimens of cimetidine on 24 h intragastric acidity were investigated in six patients with duodenal ulcer. They received placebo capsules on the first day and cimetidine on the second day. Cimetidine 0-8 g/day decreased 24 h mean H+ activity by 55% but 1-6 g/day decreased it by 67%, the difference being due to a greater nocturnal decrease in the high-dose group.

[Histamine 2 receptor antagonists in the treatment of gastric ulcer].

Eight patients with a clinical, radiology and endoscopic diagnosis of benign peptic ulcer were studied in a prospective fashion using Cimetidine (H2-Receptor antagonist). With this outgoing form of therapy the need for antiacid diminished greatly and pain totally disappeared. We discuss the possible etiological pathways of gastric ulcer and finally propose the simultaneous use of H2-Receptor antagonist and colesteramine with the goal of eliminating the two predominant factors that cause the lesion.

Relief of duodenal ulcer sysmptons by oral metiamide.

Thirty patients with symptoms of duodenal ulceration were treated for five to eight weeks in a double-blind trial with either metiamide 1 g daily by mouth or a placebo. In the 15 patients receiving metiamide there were significant reductions in nocturnal pain and antacid consumption. Daytime pain was diminished.

Red cell abnormalities associated with sulphasalazine maintenance therapy for ulcerative colitis.

Of 52 patients receiving a mean dose of 2.5g sulphasalazine/day as maintenance therapy for ulcerative colitis, 35 were found to have one or more drug-induced red cell abnormalities, which were not found in 50 normal controls or in 10 colitics not receiving sulphasalazine. Twenty-three of the treated patients had contracted red cells, an abnormality that is thought to result in mild haemolysis.

Serum -glytamyl transpeptidase activity in liver disease.

Serum gamma-glutamyl transpeptidase (GGT) activity correlates closely with the activities of alkaline phosphatase (ALP) and 5'-nucleotidase (5NT) in various forms of liver disease. Maximum elevations of all three enzyme activities are observed in diseases which particularly affect the biliary tract. Compared with the other two enzymes GGT is generally increased to a greater extent and is thus the most sensitive indicator of biliary-tract disease, while estimations of serum GGT are more reproducible than those of 5NT.

Observations on the ox cell haemolysins in human serum.

Ox haemolysin activity was estimated in 107 samples of serum, from patients with suspected glandular fever, and seventy samples from patients selected at random. The activity appeared to be in two groups: a low titre group (found in both glandular fever suspects' serum and normal serum) associated with a negative differential Paul–Bunnell test, and a high titre group (found only in the suspects' serum) associated with a positive differential Paul–Bunnell test. The `normal' (low titre) ox haemolysin was found to be removed by absorption with guinea-pig kidney suspension.
