[Evaluation of safety of prophylactic use of immunoglobulins against viral hemorrhagic fevers from horse blood sera].

AIM: Evaluate safety of prophylaxis of viral hemorrhagic fevers by specific heterologous immunoglobulins. MATERIALS AND METHODS: Clinical-laboratory examination of 24 individuals after intramuscular administration of heterologous Ebola immunoglobulin was carried out. Anaphylactogenicity of the immunoglobulins was studied by WD 42-28-8-89 in guinea pigs compared with commercial preparations. RESULTS: Immediate type reactions were not observed. In individuals with normal anamnesis the number of local reactions was 31%, general in the form of lung serum disease - 13%. In individuals with unfavorable anamnesis against the background of desensitization therapy there were almost no reactions; without it local reactions were present in 50%, mild severity serum lung disease - in 17%, medium - in 33%. Immunoglobulins against especially dangerous viral agents by anaphylactogenic properties did not differ from commercial heterologous preparations. CONCLUSION: Application of specific immunoglobulins from horse blood sera (the main means of protection from dangerous and especially dangerous exotic viral infections) with compliance by desensitization principles is relatively safe. Safe level of sensitization properties is characterized by anaphylaxis index up to 3.7 for guinea pigs.

[Automated system of phasing pulse-wave electrosurgical effects]. / Avtomatizirovannaia sistema fazirovaniia élektrokhirurgicheskogo vozdeistviia s pul'sovoi volnoi.

The authors propose an automatic system for creating stable hemostasis for an electrosurgical apparatus, which includes a scheme to assess a pulse wave and its maximum and minimum values at the site of surgical exposure, an electrosurgical apparatus, and a scheme to obtain data on the values of the pulse wave in a given patient.
