[Peptic ulcer of the stomach and duodenum in geriatrics - one disease or two?].

The authors discuss the peculiarities of the terminology of gastric and duodenal ulcers. A clinical, endoscopic and morphological study (determination of the relative area and density of sex hormone receptors in the mucous membrane of the antrum of the stomach) of 760 patients of different ages and genders was carried out. It was found that six clinical parameters (duration of anamnesis, frequency of occurrence of concomitant pathology, epigastric discomfort, belching, heartburn, hereditary predisposition) and two morphological parameters (optical density of estrogen and progesterone receptors) statistically significantly differed in men and women over 60 years old suffering from duodenal ulcer, not gastric localization.

[Effect of rations containing fluorine ion on biochemical and hematological indices of body status].

A study was made of the fluorine-ion content in the vegetables and grain grown on experimental plots of land fertilized for 4-6 years with fluorine-containing fertilizers: active slurry potassium tetrafluoroborate and sodium fluorosilicate. It was found that the fluorine-ion content in individual samples of the vegetables and grain was increased 2-32-fold as compared to that in the control samples. As for the diet, the total content of fluorine-ion was increased 6.
