    Title translation Epidural block in the surgical treatment of cholelithiasis.
    Abstract The article analyses surgical treatment of patients with cholelithiasis (231 persons) who were operated on with the use of a "pure" epidural block (59 patients), epidural block in combination with surface endotracheal nitrous oxide anaesthesia (100 patients), and general many--component anaesthesia (72 patients). The results show that epidural block is an effective method of neurovegetative protection of the organism from an operative trauma, provides rapid recovery of the organism for a state of operative stress, and is conducive to reduction of the number of postoperative complications. Administration of hydrocortisone and ephedrine is expedient for the prevention of arterial hypotension and its correction.

    Abstract Background: Proton computed tomography (pCT) and radiography (pRad) are proposed modalities for improved treatment plan accuracy and
    Material and methods: The CNN was trained by simulation and reconstruction of tens of millions of proton and helium tracks. The CNN filter was then compared to simple energy loss threshold methods using the Area Under the Receiver Operating Characteristics curve (AUROC), and by comparing the image quality and Water Equivalent Path Length (WEPL) error of proton and helium radiographs filtered with the same methods.
    Results: The CNN method led to a considerable improvement of the AUROC, from 74.3% to 97.5% with protons and from 94.2% to 99.5% with helium. The CNN filtering reduced the WEPL error in the helium radiograph from 1.03 mm to 0.93 mm while no improvement was seen in the CNN filtered pRads.
    Conclusion: The CNN improved the filtering of proton and helium tracks. Only in the helium radiograph did this lead to improved image quality.

    Title translation Study of lymph nodes in lung cancer in experimental animals using the indirect lymphography method and a computer.
    Abstract Combination of the "PEEC-D" microfocal X-ray apparatus with the DED-3 computerized detector of X-radiation and an electronic computer made it possible to produce a considerably magnified image of the lymph nodes on the display screen and study their structure. The mediastinal lymph nodes differ in structure in different pathological conditions, due to which they can be differentiated. Under normal conditions the lymph nodes have a regular density and a characteristic microcellular structure due to the uncontrasted follicles. In chronic inflammation the lymph nodes have an indistinct capsule. The contrasting and structural pattern of the parenchyma are greatly diminished. The enlarged uncontrasted follicles are spherical. Lymph nodes containing metastases change their configuration sharply and undergo three-dimensional transformation. In the presence of metastases the lymph nodes multiply by separating part of the node.
