Histopathological data on six cases of hypothyroidism accompanying muscular chronic disease.

This study was carried out on 6 patients with myxedema that showed major muscular alterations. Light and electron microscopic examinations of the striated muscle structure revealed myxedematous myopathy lesions. Considering the existence of several hypotheses regarding the pathogeny of muscular alterations, the authors discuss the likelihood of a myogenic syndrome induced by an immunity deficit in hypothyroidism.

Gastrin (G) cells in gastric carcinoma.

The behaviour of gastrin cells in the antral mucosa in gastric carcinoma was electron microscopically investigated using specimens of surgically resected stomachs. The results pointed out that in gastric carcinoma there takes place a change of the types of G cell population in the antral mucosa. In this condition, a significant fact was the predominance of intestinal G cells, known to store mainly G 34.

Gastrin cells in stomach and duodenal ulcers.

By means of cytochemical and electron microscopy methods, the behavior of gastrin cells in ulcers of the stomach and duodenum were investigated. The study was performed on specimens of surgical resection from stomach and duodenal ulcers with gastric normacidity. The results point out a significant decrease of gastrin cells in stomach ulcers in comparison with the duodenal ones. These findings in stomach ulcers were attributed to the high intensity of gastritis lesions, histopathologically evidenced. Electron microscopy revealed that gastrin cells were loaded with secretion granules presenting suggestive images of synthesis activity.

Enterochromaffin cells (EC) of the antropyloric mucosa in gastric and duodenal ulcers.

Enterochromaffin cells (EC) within the antropyloric mucosa in resected stomach from patients with gastric and duodenal ulcers were investigated by means of cytochemical and electron microscopy. The proliferation of antral EC cells was pointed out; among them EC cells of gastric and intestinal type were identified. The proliferation of antral EC cells seems to be related to the intensity of chronic gastritis.
