Polymer domain growth in ordered liquid crystalline matrices.

The growth of polymer domains in the isotropic, nematic, and smectic matrices is studied by the light scattering. In the smectic and isotropic matrices the growth is diffusive, and in the nematic matrix it is influenced by the elastic forces. The scaling is obeyed. A crossover to the wetting fast-mode hydrodynamic regime is also observed at long times. In order to perform these measurements we had to eliminate the multiple scattering of light.

[Small intestine obstruction caused by primary malignant neoplasms].

The authors presented 4 cases of primary malignant neoplasm of the intestine caused by small intestine obstruction. These patients underwent emergency surgery. In all cases, a segmental resection of the intestine was performed. There were two cases of adenocarcinoma and two cases of carcinoid. Three patients were complementarily treated using chemotherapeutics. One of them died two years post operation. The last three patients survived 0.5-5 years post operation.

[Primary malignant neoplasms of intestine].

The authors presented 6 cases of malignant neoplasms of intestine. Five of them were undergone emergency surgery, while one elective, due to complaints notified previously for a longer time. In all cases a segmental resection of intestine was done. Two patients were complementarily treated using chemiotherapeutics. Three patients survived 2-5 years after the operation. The last three patients are under the further follow up.

[Gallstone ileus].

Since 1986 till 1996 in the Third Department of Surgery of the Collegium Medicum of the Jagiellonian University in Cracow, nine patients with biliary ileus were operated. Initial diagnosis, additional tests results, concomitant diseases, kinds of operative procedures and complications were analysed. Biliary ileus is still generally recognized during operation. Endoscopy, X-ray examination with contrast, ultrasound, and computed tomography are worth recommendation in preoperative diagnosis. Early decision about operative treatment and application of antibiotic prophylaxis may have an influence on improvement of treatment results.

[Primary gastrointestinal lymphomas].

The paper presents clinical signs, diagnosis, treatment and therapeutic results in the group of patients with a primary gastrointestinal lymphomas. All of the patients had a surgical procedure: 5 of them were operated on according to a fixed plan and 3 had an emergency operation. 6 patients were subjected to chemotherapy and radiotherapy. The patients were analyzed along with the obtained therapeutic results.
