A nonlinear evolution of the structure, morphology, and optical properties of PbS-CdS films with cadmium nitrate in the reaction mixture.

Herein, we describe the nonlinear processes for the formation of thin films of the PbS-CdS system using chemical bath deposition with a gradual change in the cadmium nitrate content in the reaction mixture. The morphology of films was studied via scanning electron microscopy and atomic force microscopy. The mechanism for the formation of thin-film compounds can be considered as cluster-particle aggregation (diffusion-limited aggregation).

[Optimization of indirect endolymphatic injection of isoniazid in pulmonary tuberculosis].

The authors have substantiated and studied the use of lymphotropic (interstitial) injection of 1% isoniazid solution in the complex therapy of patients with pulmonary tuberculosis. The method provides active interstitial functioning of the diseased organ. This leads to a substantial improvement of immediate results of treatment in patients as accelerated closure of decay cavities and double cessation of bacterial isolation.

[Pathomorphosis of infiltrative pulmonary tuberculosis: clinical aspects].

Based on the data available in the literature and their own findings, the authors have established that the pathomorphism of infiltrative pulmonary tuberculosis in the preantibiotic age was characterized by negative features, then underwent phases of positive changes and relative stabilization, thereafter it again acquired obviously marked negative peculiarities. At present, the clinical features of new cases of infiltrative pulmonary tuberculosis in Perm residents are the predominance of acute onset (67.3%), disseminated (55.
