[Possibility of using the BI-3 jet injector for gamma globulin administration].

The results of weighing glass flasks before and after "shooting" preparations varying in viscosity into these flasks from type BI-3 jet injectors indicated that the ejected dose of gamma globulin corresponded to the preset value. Studies carried out by means of radioisotyope technique with the use of Tc99m showed that the intramuscular injection of gamma globulin with type BI-3 jet injector resulted in 75% of the preset dose penetrating the body. For this reason in mass vaccination against Botkin's disease the dose of the preparation in the injector should be increased by 1/3.
