[The effect of indomethacin and leukinferon on the thromboxane B2 level in the blood plasma of patients with endometrial cancer in the perioperative period]. / Vliianie indometatsina i leikinferona na uroven' tromboksana B2 v plazme krovi bol'nykh rakom éndometriia v perioperatsionnom periode.

The paper discusses the effect of indomethacin, leukinferon as well as their combined effect on blood thromboxane B2 (TxB2) level in 40 endometrial cancer patients in the perioperative period. Perioperative treatment with indomethacin was followed by a significant decrease in blood TxB2 level before surgery and in the postoperative period. Treatment with leukinferon exerted similar effect which, however, was less pronounced than that of indomethacin. The effect was most apparent when the two drugs were combined. The influence of indomethacin and leukinferon on metabolism of arachidonic acid in tumor cells and those of the immune system of endometrial cancer patients are discussed as well possible role of eicosanoids in the pathogenetic mechanism of growth and dissemination of reproductive tumors.

[Effect of electroanesthesia and neuroleptanalgesia on blood plasma beta-endorphin level during surgical intervention in cancer patients]. / Vliianie élektroanestezii i neiroleptanalgezii na kontsentratsiiu beta-éndorfina v plazme krovi pri operativnykh vmeshatel'stvakh v onkologii.

Beta-endorphin release was studied in 40 patients after surgery for thyroid cancer or after femoral amputation due to malignant malformations in bones and soft tissues of the lower extremities. In thyroid surgery beta-endorphin release was more marked under neuroleptanalgesia than under combined electroanesthesia. A correlation between beta-endorphin and ACTH levels has been established. It indicates a stress nature of neuropeptide release. In patients with femoral amputation an increased beta-endorphin release was not observed. Possible mechanisms of beta-endorphin level elevation are discussed in terms of modern concepts of pain modulation.
