[The effect of progressive incremental exercise on some parameters of hemostasis].

In 18 sportsmen the platelet count, thrombin time, prothrombin time, activated partial thromboplastin time (APTT), cloting factors (F):I, VII, VIII and fibrin/fibrinogen degradation products (FDP) were measured before, immediately after progressive incremental exercise--and 30 min later. All post-exercise changes of the values were corrected for the plasma volume changes, which were calculated from hematocrit values. Platelet count, thrombin time, prothrombin time FI and FVII did not change significantly after exercise. Immediately post-exercise APTT was significantly shortened, but FVIII and FDP were significantly elevated. 30 min later FDP level normalized but FVIII and APTT changes persisted. The obtained data show that the applied physical exercise caused shift of the existing balance between coagulation and fibrinolysis towards hypercoagulability. They also confirm the necessity of taking into account post-exercise hemostasis changes in cardiological rehabilitation and endurance training in adults.

Pregnancy associated diffuse malignant fibrous mesothelioma of peritoneum. Immunohistochemical studies of ectopic decidual reaction and concomitant myofibroblastic and mesothelial proliferations.

A case of diffuse proliferations in the peritoneum in a 24-year-old woman several months post partum has been reported. Multinodular growth of myofibroblastic cells without atypia was observed, which predominated and revealed a positive immunohistochemical reaction to muscle-specific actin and vimentin, and dispersed clusters of mesothelial cells showing a positive reaction to cytokeratin and vimentin, with moderate atypia and scarce mitotic figures. On cesarean section the greater omentum contained an ectopic decidua in the form of a nodule. Decidual cells, in part transforming into spindle-shaped cells, showed the presence of desmin. Multifocal proliferation of myofibroblasts, most probably of metaplastic type, concomitant with pregnancy-induced peritoneal deciduosis and diffuse progressive mesothelial proliferations has been identified.

Silver-binding nucleolar organizer regions (AgNORs) in bronchial tumors.

Various AgNOR parameters were measured using the computer-aided image analysis in the normal bronchial epithelium (n = 13), in squamous cell carcinoma (n = 25) and in small-cell carcinoma (n = 11). The number and area of AgNOR dots were the highest in squamous cell carcinoma. In small cell carcinoma and in the normal epithelium the values were significantly lower. The number of AgNOR separate locations was higher in tumors in general. The size of single AgNOR dots showed differences between squamous cell carcinoma and small-cell carcinoma. Ratio of AgNOR dot area to nuclear area was similar in various pathological lesions and normal epithelium. There was a positive correlation ( < or = 0.0001) between the number and area of dots, the number of AgNOR separate locations, the area of single AgNOR dots on one hand and nuclear area on the other.
