[The dynamics of biochemical blood indicators in patients with hemophilia and posttransfusion hepatitis receiving hepatotropic therapy].

The sample of 128 patients with hemophilia aged from 1 to 71 years (Me 32) was examined. The study established that 109 patients (85.2%) had hemophilia A and 19 patients (14.

[The IgG subclasses in patients with inhibitory form of hemophilia infected and noninfected with viruses].

The sample consisted of 102 patients with hemophilia infected and non-infected with hepatitis viruses. It is established that in case of inhibitory form of hemophilia concentration of IgG increases at the expense of subclass II and in case of non-inhibitory form of hemophilia valuable increase of concentration of IgG occurs at the expense of subclasses I, II and III under concomitant chronic hepatitis. No significant differences between these groups in levels of antibodies to factors VIII and IX is established.

[Evaluation of methods of studying hemostasis].

Comparative assessment of the methods for studies of platelet aggregation, used in the USSR and in Hungary, has demonstrated the usefulness and reproducibility of both. The reagents manufactured by Reanal (Hungary) are characterized by a higher sensitivity, inducing a more distinct and rapid formation of aggregates. This fact is of particular importance when no aggregometers are available and the 'snow whirl' is assessed visually.
