Abstract: FIELD: medicine. 
     SUBSTANCE: invention refers to medicine, namely to endoscopic examinations. First stage involves lavage of a deformed bronchus and, additionally, two bronchi of the same order adjacent to the deformed bronchus. Atypical cells, as well as acid-fast mycobacteria (AFM) are determined in bronchoalveolar fluid by methods of inoculation and microscopy of sediment according to Ziehl-Neelsen. At the second stage, brush biopsy is performed from the mouth of the deformed bronchus and additionally brush biopsy of two bronchi of the same order adjacent to the deformed bronchus. Obtained material from each bronchus is deposited on two separate slides for subsequent cytological examination and bacterioscopy of the sediment by the Ziehl-Neelsen method. At the third stage, a pinch biopsy is performed from a spur of a deformed bronchus for histological examination with preliminary creation of imprinted smears for additional cytological examination. Before placing the fragments of the biopsy tissue into a transport container with 10 % formalin solution, imprinted smears are made on 1–2 slides for additional cytological examination. At the fourth stage, a brush biopsy is performed from the distal bronchus of the previous order, from which the deformed bronchus extends. Material is applied on two slides. That is followed by cytological examination and bacterioscopy of the sediment by the Ziehl-Neelsen method. If observing at least one of the stages of atypical cells, the tumour process is verified; if observing the AFM, the tuberculosis process is detected; if the tumour and tuberculosis lesions are excluded, the nonspecific inflammatory genesis of tracheobronchial tree deformations is verified. 
     EFFECT: method allows to confirm or exclude tumour or tuberculosis or nonspecific inflammatory genesis of pathological changes, to increase accuracy of diagnosis due to verification of pathological changes not only in deformed bronchus, but also in adjacent anatomical areas.

Abstract: FIELD: radio engineering. 
     SUBSTANCE: invention relates to the field of radio engineering and can be used in radio communication systems with packet data transmission to improve their noise immunity. In the method for packet data transmission, noise-like signals form two binary quasi-orthogonal pseudo-random sequences of maximum length, synchronizing (SS) and informational (IS). At each repetition period of the IS, a modulated sequence (MS) is formed by cyclically shifting the IS of the initial length by the number of elements determined by the transmitted information symbol. IS and MS are extended by one element, and the joint venture is shortened by a certain number of elements. At the beginning of the transmission of each data packet, the SS and IS are phased between each other and a clock signal is transmitted, which is formed by phase manipulation of the carrier frequency signal by the SS sequence and an additional phase shift by 90 degrees if the current values ​​of the SS and IS do not match. The duration of the clock signal is equal to the product of the duration of one element of sequences and a number equal to the least common multiple of the number of SS elements and the number of IS elements. When transmitting data, the carrier frequency signal is manipulated in phase by a sequence that is the modulo two sums of the SS and MS. 
     EFFECT: increasing the noise immunity of the packet data transmission system.
