[An automated system for the collection and processing of clinico-diagnostic information in developing methods for treating dental defects by using dental implants].

A dialogue medical information system "Dental Implant" is described, intended for the collection and analysis of clinico-diagnostic information with the aim of developing methods for the treatment of patients with dentition defects, making use of dental implants. This automated system permits a rapid and effective analysis of surgical and orthodontic complications and is intended for operation by a non-programmer.

[Oxygen status and regional blood flow in the gingival mucosa as affected by lower body negative pressure].

Five test subjects were exposed to lower body negative pressure (LBNP). During exposure their regional circulation and oxygen balance of the gingival mucosa were measured and electrocardiography and kinetocardiography were performed to calculate parameters of the left heart function. The study showed a distinct correlation between LBNP tolerance and the level of compensatory reactions of the gingival mucosa blood flow and the cardiovascular system as a whole. The subjects with a high LBNP tolerance showed well pronounced regional compensatory reactions of the gingival mucosa that were not accompanied by significant changes in the left heart function. The subjects with a moderate tolerance exhibited either weak or no regional compensatory reactions of the gingival mucosa and significant changes in the left heart function.

[Oxygen balance and regional blood flow in the gingival mucosa during exposure to head-pelvis (+Gz) acceleration].

The information content of a new contact rheopolarographic procedure used to determine the oxygen balance and regional circulation of the gingival mucosa was measured, bearing in mind the applicability of the procedure as an objective index of human tolerance to +Gz acceleration. It was found that the parameters of the oxygen balance and regional circulation of the gingival mucosa were well correlated with blood pressure in the floor of the auricle. In contrast to the traditional methods for assessing tolerance to acceleration, the new procedure provides information about the health condition of the centrifuged subjects on a continuous basis. Variations in the oxygen balance and regional circulation of the gingival mucosa helped to identify compensatory reactions of the cardiovascular system in response to +Gz acceleration.
