[Carriers of thrombophilic factor among women with preeclampsia (preliminary report)].

The aim of this study was to determine whether inherited thrombophilia increases the risk of mild preeclampsia. Twenty five women who developed mild preeclampsia and 49 controls--women with previous uneventful pregnancies, were tested for factor V Leiden, C677T gene variant of methylenetetrahydrofolate reductase (MTHFR), polymorphism 4G/5G in plasminogen activator inhibitor 1 (PAI 1), polymorphism A1/A2 in platelet glycoprotein IIb/Illa (GIPrllb/llla A1/A2). The higher but not significant prevalence of C677T gene variant and polymorphism A1/A2 in women with preeclampsia compared with controls was found: 32% and 12.

[Clotting induction in the mesenterium and erosive stomach mucosa in wistar rats as the result of a catenoidal ultrasonic transducer].

The ultrasonic transducers and instruments used in surgery operate in the range of 1-10 MHz and release significant heat in the surroundings. They need additional cooling system which significantly raises the cost and impedes the equipment operation. Hemostasis can be successfully achieved by employing ultrasonic transducers that operate in the kilohertz range, avoiding the occurrence of inadmissible tissue overheat outside the area of the transducer performance.

[Treatment of Ewing's sarcoma with 2 different protocols].

Since 1985, 54 with localized Ewing's sarcoma of bone were treated at the Onco-Orthopedics Clinic of the Sofia University Hospital (Sofia, Bulgaria). Thirty-two patients received the classical four-drug combination with doxorubicin, dactinomycin, vincristine, and cyclophosphamid. The last 22 patients were treated with six-drug protocols where cisplatinium and ifosfamid were added to the standard four-drug regimens.
