[Combined treatment of long tubular bone fractures and false joints using the bioplastic material collapan (Russia)].

This experimental morphological study on 32 dogs was designed to evaluate the efficiency of hydroxyapatite containing preparation collapan used to promote healing of segmented femur defects. Implantation of collapan was shown to greatly contribute to the formation, maturation and remodelling of bone callus. Combined treatment of 165 patients with comminuted fractures and 148 ones with false joints of long tubular bones using collapan implants proved to efficaciously promote bone consolidation in 99.4% of the total 313 subjects. Collapan activated reparative osteogenesis, reduced the duration of hospitalization, the frequency of inflammatory complications, and the requirement of secondary inpatient care.

[Reactions of the circulatory system to static load in athletes and persons less well trained]. / Reaktsii sistemy krovoobrashcheniia na staticheskuiu nagruzku u sportsmenov i malotrenirovannykh lits.

Different cardiovascular responses were assessed in untrained men (1 group) and sportsmen (2 group). The 2 group responses were more economic due to effective vascular reactions, whereas in the 1 group the increase of blood flow during exercise was provided ba cardiac output and to a lesser extent by vascular reactions. Physiological value of the responses and vegetative prognostic criteria of fatigue limiting physical work, are discussed.
