[Low-grade endometrial stromal sarcoma firstly localized in colonic mesentery].

There are only few papers describing extrauterine localisation of endometrial tumor sarcoma. Pathogenesis of this tumor is still not clear. Most of the authors suggest the heterotopic Mullerian ducts to be the origin of such tumors. We describe a case of 53 year old woman with endometrial tumor sarcoma localized in the mesenterium of the colon. Diagnostic problems and differential diagnosis is presented. The authors suggest to immunohistochemical methods (CK desmin) to facilitate diagnosis.

[Proliferative activity of blood microvascular endothelium of intestinal mesentery during rat postnatal ontogenesis].

The study of mitotic activity of mesenteric microvascular endothelium cells (EC) in 4-, 12-, and 30-day old rats has been carried out using following parameters: number of labeled nuclei per vessel, or per 100 microm of vascular length, or per 1 mm2 of endothelial surface area, as well as shares of labeled EC and of vessels with labeled EC, have been estimated. The highest density of labeled nuclei was revealed in the pericapillary vessels in all rats. Its values were significantly higher in 12-day-old rats and were the lowest in 30-day-old ones.

[Lymphangioma of the mesentery. A rare cause of acute abdominal pain syndrome in adults].

We report about one case of cystic lymphangioma of the jejunum in a 27-year-old woman admitted to hospital for abdominal pain. The study of this case and the review of the literature enabled us to bring out the main characteristics of the lesion: rarity in adults, benignancy, mode of occurrence--most often painful--, radiological--and particularly CT--features, diagnosis based on histological findings only, and lastly, treatment with surgical exeresis that must be complete to prevent recurrence.

[The link between the parameters of the thrombus formation process and blood flow velocity in the microvessels of the rat mesentery].

The role of shear rate in the processes of thrombocytes adhesion and aggregation was studied in vivo and in vitro. Certain parameters were obtained describing the thrombo-formation process in the rat mesenteric venules in different blood flow velocities. The experimental model took into consideration the dependence of the thrombocytes activation period on the distance from lesioned portion of vessel's endothelium.

[Mesentery capillary barrier in rats injected intravascularly with ascitic Zajdela hepatoma. III. Effect of serotonin and histamine on the extravasation of the tumor].

The addition of serotonin or of histamin with tumoral cells of ascitic Zajdela's hepatoma and their injection in aorta induce plain hemodynamic changes and increase the tumoral extravasation. So only cells blocked in thrombi are observed in blood vessels. Therefore, serotonin and histamin do facilitate tumoral cells extravasation, allowing so a better metastatic diffusion in this experimental pattern.
