[Changes in lymphocyte subpopulations in relation to anesthesia procedure].

44 patients undergoing comparable gynaecological operations received either halothane- modified neuroleptanaesthesia or a combination of epidural and NLA. Monoclonal antibodies were used to determine 8 different lymphocyte subpopulations in blood samples drawn before and after anaesthesia and on the first postoperative day. Cell populations were counted by fluorescent microscopy.

[Evaluation of the value of ultrasound in the diagnosis of gynecologic tumors].

The value of ultrasound (US) is analysed by means of ROC-curves (receiver operating curves) taking into consideration both the sensitivity and specificity of the method, as well as the prevalence of particular tumours in the examined group. US diagnosis is compared with clinical and surgical findings. The authors have found that the degree of reliability achieved by either the clinical or the US method of diagnosing myomas is almost the same.
