[Surgical treatment of large intestines obstruction caused by colorectal cancer].

Large intestinal obstruction like a life-threatening steatement is a subject of investigation in the present study. In such prospection are included 65 patients undergone surgery for large intestinal obstruction of cancer in period of seven years. Analyzed are after undertaken surgical procedures.

[Morphometric rationale for utilization of peripheral nerves of the human fetus as vascularized allografts].

The authors performed morphometric section studies of the peripheral nerves of 25 human fetuses of 17-26 week development. The purpose of the study was determination of the technical possibility of using revascularized nerves of the human fetus as grafts for replacement of post-traumatic defects in the peripheral nerves. The peripheral nerves of the upper limbs of fetuses of the indicated developmental periods were found to be formed morphologically.

[The microsurgical transplantation of vascularized bone from a human fetus to man].

On the basis of the possibilities of microsurgical techniques and the results of some experiments conducted for the purpose of studying the "microsurgical" morphometry of various areas of the body of a fetus, determining the viability of fetal tissues in cold and thermal anoxia, working out microsurgical methods and the operative techniques, and solving organizational problems, three operation were carried out in the clinic for transplantation of vascularized fetal humerus (in one case together with the ulna and radius) to three patients with defects in the bone skeleton of the hand. Immunosuppression was not undertaken. Control over the viability of the brephotransplant was conducted by ultrasonic dopplerography on a vascular pedicle, radioisotope scintigraphy, roentgenography, and histological study in aspiration biopsy.
