[X-ray contrast and radioisotope angiography in tumors of the neck].

Comparative results of angiography and radioisotope scintigraphy with technetium (Tc 99 m) in 38 patients having different jugular tumors are reported. Both methods were found to correlate well with respect to the estimation of tutor blood supply. Radioisotope scintigraphy is a more simple, physiological and practically safe method of investigation, and the former should be recommended for estimating the degree of tumors vascularization, the state of brain circulation and also in cases when angiography proves to be unfeasible.

[Comprehensive arteriophlebographic study in the diagnosis of tumors of the female genitalia].

Complex arterio-phlebographic study was performed in 65 patients. The results obtained made it possible to determine diagnostic opportunities of pelvic arteriography and intrauterine phlebography employed in the same patients. It was found that the complex investigation is a valuable adjunct in establishing the differential diagnosis between tumors of the uterus and adnexa; it aids to determine exactly the localization of fibromatous nodes and their relationship with the uterine vessels in planning an operative intervention, and to elucidate the character of tumor process in the adnexa.

[Changes in the thoracic duct and lymphodynamics in neoplastic diseases].

X-ray contrast study of the thoracic duct was conducted in 35 patients with various neoplasms of the chest and upper abdomen, as well as in tumor involvement of lymph nodes, located proximally to the main lymphatic collector. Pathological changes in the thoracic Duct and central lymphodynamics, observed in neoplastic lesions concerned, are described.

[Lymphographic semeiotics of inflammatory and dystrophic lesions of the lymph nodes in the light of morphological data].

The authors report clinica, roentgeno-lymphographic and morphological findings in 164 patients whom lymph nodes showed various changes of non-tumor origin, 584 lymph nodes being studied by aimed lymphographic and morphological correlations. The changes observed were subdivided into 2 groups: diffuse and focal. Diffuse inflammatory and reactive changes, and multiple micrometastases as well, are manifested by an analogous lymphographic picture. In focal hyperplasia a lymph node is somewhat increased in size, it shows smooth and distinct contours, defects of filling and absorption.

[Effect of bradykinin on blood circulation in the human celiac artery bed].

Selective angiography and direct measurements of the arterial pressure in the celiac artery was used to study the influence of bradykinin on the blood circulation in healthy organs in the celiac region in 24 patients. A high sensitivity of the vessels to the action of bradykinin (0.1--10 mkg) was revealed: it decreased the blood pressure, increased the rate of blood flow, increased the diameter of arterial and venous vessels, arterio-venous anastomosis, increased the number of functioning capillaries. No differences were found in the reaction of the vessels of the liver, spleen pancreas, duodenum and the stomach to bradykinin.
