Spectroscopic features of ultrahigh-pressure impact glasses of the Kara astrobleme.

The state of substances under ultrahigh pressures and temperatures (UHPHT) now raises a special interest as a matter existing under extreme conditions and as potential new material. Under laboratory conditions only small amounts of micrometer-sized matter are produced at a pressure up to 100 GPa and at room temperature. Simultaneous combination of ultrahigh pressures and temperatures in a lab still requires serious technological effort.

[The therapeutic efficacy of a sodium chloride mineral water in chronic gastritis patients with secretory insufficiency].

The paper presents pilot experience with oral use of sodium chloride mineral water Makov I for chronic achlorhydric gastritis. Altogether 734 patients were studied. Of them, 217 were evaluated for intragastric pH upon administration of a single water dose, 32 upon a course of treatment.
