[The use of plasma from donor convalescent patients in the combined treatment of peritonitis].

The article analyses the treatment of 12 patients with diffuse purulent peritonitis in whom the titers of specific antibodies against microflora causing peritonitis were corrected in the period of secondary immunodeficiency. The authors suggest a new method for the treatment of peritonitis which is based on inclusion of convalescents' plasma after peritonitis in the therapeutic complex. This plasma contains specific antibodies against the cultured microflora in high titers and is a polyvalent hyperimmune medium which makes it possible to cause an effect on the level of humoral immunity. This improved the results of treatment: the titres of specific antibodies against the cultured microflora grew, such complications of diffuse peritonitis as the formation of circumscribed abscesses in the abdominal cavity and suppuration of the postoperative wound were encountered less frequently, mortality reduced by 16.6% as compared to the control group. The efficacy of the suggested methods was also proved in experiments on 164 animals.

[Programmed laparotomy in the diagnosis and therapy of pathology of the abdominal cavity].

The authors analyse the performance of programmed laparotomy for dynamic visual observation over the condition of the abdominal organs in 3 patients when (as they claimed) laparoscopy would have produced no effect. The article reports on the efficacy of programmed laparotomy conducted by the method suggested by the authors in 15 patients with purulent peritonitis for repeated cleansing of the abdominal cavity.

[Growth of the jugular lymph sacs and establishment of the topography of the cervical portion of the thoracic duct during early human ontogenesis].

In 196 human embryos, prefetuses, fetuses and newborns, by means of a complex of morphological methods, development of the jugular lymphatic sacs and the process of settling of the thoracic duct cervical part topography have been studied. The jugular lymphatic sac anlages take place on the 6th week of the development. From the lymphatic cleft, situating in the mesenchyme near the anterior cardinal veins, multichambered cavities laid with endotheliocytes are forming,--the jugular lymphatic sacs. Connection of the initially close lymphatic sacs with the venous system takes place secondarily by the end of the embryonic period of development. In the area of the sac ostia a valve is formed, that makes morphological premises for unidirected lymph flow into the venous system. The lymph nodes developing at the place of the reducing jugular lymphatic sacs, ensure formation: from the left jugular lymphatic sac--the cervical part of the thoracic duct, from the right jugular lymphatic sac--the right lymphatic duct and the jugular and the subclavicular lymphatic trunks. Variability in the form and topography of these structures are determined both by the form and construction of the jugular lymphatic sacs and by developmental peculiarities of the lymph nodes at their place. The process of settling of the thoracic duct cervical part topography depends on age changes of its size and form, as well as on development of structures situating nearby, and by the time of birth it is not completed.

[Development of the thoracic duct in the prenatal period of human ontogeny].

In 40 series of histological sections performed in human embryos and prefetuses from 4 up to 20 weeks of development, as well as in 20 corpses of fetuses and stillborns, it has been stated that the anlage of the thoracic duct appear in 6-7-week-old fetuses as lymphatic clefts surrounded with mesenchymal cells that are situated near large veins in the areas of the most active morphogenesis. Connecting with each other, the clefts form the jugular and retroperitoneal lymph sacs and a well branching network of canals. From the latter, on the 7th-8th week of development a plexus of lymph vessels appear, and later on (on the 8th-9th week)--bilaterally situating trunks of the thoracic duct. Further development of the thoracic duct is connected with the lymph nodes formation, their germs appear on the 9th-10th week along the course of the left trunk, as well as along the ductal branches and anastomoses. The formation of the lymph nodes results in reduction of some trunks and plexuses of the thoracic duct. Owing to this, its form in 14-15-week-old prefetuses resembles the one in newborns. Disturbances in the formation processes of the lymph nodes along the course of the reducing ductal areas, as well as their formation along the course of its main trunk can result in various structural variants of the thoracic duct in children and grown-up persons. Histogenesis of the thoracic duct wall and formation of the lymph nodes are not completed by birth.
