[Current ways of preventing postresectional bronchial fistulas in pulmonary tuberculosis].

The paper presents the data of a follow-up of 51 patients in whom a bronchial stump suture was additionally fixed at surgery by applying Tochocomb plates (in 30 patients) or an autoangiograft from the removed lung (in 21 patients) in order to prevent a bronchial fistula. The preliminary findings were positively appraised. The authors recommend that this procedure be used in phthisiosurgery and surgical pulmonology.

[Characteristics of the precipitation reaction at the stage of antigen-antibody complex aggregate formation studied by a spectroturbidimetric method].

The possibility of using the spectroturbidimetric method, one of the variants of the light scattering method, for the determination of the characteristics of the second phase of the antigen-antibody reaction was shown examplified by the interaction between rabbit antiserum and bovine serum albumin. The parameters of the aggregates formed in the process (their average size, their concentration by weight and number) were calculated for the whole period of the reaction and with its components taken in different proportions. The precipitation curve plotted by the above method correlated well with the result of an independent determination at an extinction coefficient of E278.
