Antral G- and D-cell counts in chronic renal failure.

Antral somatostatin- and gastrin-producing cells (D and G cells) were studied in a group of patients with chronic renal failure (CRF) in comparison with a control group. Gastric acid secretion and serum gastrin, phosphate, and parathormone (PTH) levels were also evaluated in every patient. The group with CRF showed a mild increase both in G- and in D-cell denisty. In this group serum phosphate and PTH levels were higher than normal, showing hyperparathyroidism in every patient. A direct correlation was found between G-cell density and parathyroid function in patients with CRF. Hyperparathyroidism, therefore, seems to play a role in the mechanism of increased serum gastrin levels in CRF.

[Cimetidine in the treatment of peptic ulcer].

Cimetidine, a non-thiourea-containing histamine H2-receptor antagonist, has been employed in the treatment of peptic ulcer. We studied 50 patients, partly with double-blind method, and partly in a free trial. Duodenal ulcers were completely healed in 80% of the cases, at the control endoscopy after a 4-week period of treatment with cimetidine (1000 mg/day). Peptic ulcer in general healed in 76% of the cases. Gastric secretion was significantly reduced after cimetidine. An important improvement in subjective symptoms was noted in every patient. No toxic effect was noted.

[Acute hyperparathyroidism. Emergency surgical operation in a case of hypercalcemic coma].

A case of acute hyperparathyroidism complicated by oliguric renal failure successfully resolved only after surgical removal of a parathyroid adenoma is reported. The need for early diagnosis of this rare condition is stressed and the commonest and most recent techniques for investigating primary hyperparathyroidism are discussed. In agreement with other reports, the importance of the earliest possible surgery, without which prognosis is almost always poor, is reiterated.

G-cell counts in antral endoscopic biopsies by immunofluorescence.

Antral gastrin-producing cell (G-cells) were counted by an immunofluorescence technique in the antral biopsies obtained at endoscopy from 67 subjects; they included patients with duodenal ulcer, gastritis, and individuals with a normal gastric mucosa. The G-cell count was significantly lower (P less than 0.01) in patients with duodenal ulcer (142 G cells per mm2) in comparison to normal subjects (327 G cells per mm2). No statistically significant correlation was found between the G-cell number and any of the other parameters tested (pentagastrin test, basal serum gastrin and its response to a standard meal).

[Treatment of Parkinson's syndrome with a combination of levodopa and carbidopa].

It is widely known that administration of L-Dopa benefits patients with Parkinson's syndrome and combination of this drug with decarboxilase does it to a greater extent. In the present study 20 patients with Parkinson's syndrome received MK 486, a combination of L-Dopa and Carbidopa 10:1 (250 mg of the fomer and 25 mg of the latter). The aim of this study was to evaluate therapeutic activity of this drug combination. It was found that MK 486 is effective for controlling clinical manifestation in Parkinson's syndrome. Although side effects were seen frequently, they diminished or disappeared after time of drug administration.
