[Anti-oxidative therapy of pancreatitis--an 18-month interim evaluation].

99 patients affected with acute pancreatitis of different genesis were treated in hospital (necrotizing n = 38, mild form n = 61) from May 1990 to November 1991. Nearly 80% of these illnesses were ethanol-induced, 12% were of biliary origin. 90 patients were submitted to an adjuvant antioxidant therapy with selenium and D-alpha-tocopherol (necrotizing form n = 29, mild form n = 61). The average lethality rate of 34% (1982-1989) fell to 1.1% (1 female patient with biliarily induced pancreatitis). No lethal courses were observed in alcohol-induced, idiopathic, post-traumatic, and post-operative forms. Clinical courses proceeded more easily under adjuvant antioxidant therapy, surgical treatment was not necessary. A treatment at reasonable costs can be made in all general internal wards.

[Acute pancreatitis--a free radical disease. Decrease in fatality with sodium selenite (Na2SeO3) therapy].

Malonic dialdehyde as an indirect marker of the lipid peroxidation was found increased in the acute pancreatitis compared with persons of the same age and sex. Its concentrations inversely correlated to those of the serum calcium during the course of the disease and additionally they proved to be indicator of the prognosis. Postulating that the acute pancreatitis must be a "free radical disease", in a randomized clinical study the adjuvant therapy of the acute necrotizing pancreatitis (n = 8) with sodium selenite was carried out in a daily dose of 500 micrograms. The lethality of the control group was 89% (8 out of altogether 9 patients), no patient died in the therapy group. By the selenium therapy within 24 hours a normalization of the serum calcium and a decrease of the increased MDA-values could be achieved. It was concluded that by selenium increased activities of the phospholipid-hydroperoxide-glutathione peroxidase were induced, by means of which a peroxidation protection of membrane fatty acids, an inhibition of the activity of phospholipase A2 and an interruption of the arachidonic acid cascade must have been reached.

[Report of experiences with fibrinolytic therapy of deep venous thrombosis of the legs].

It is reported on the fibrinolytic therapy of thrombosis of the deep veins of the legs, the pelvis and the arms. This treatment was analysed in 18 patients who were treated between 1983 and 1986. The possible causes of the development of thrombosis, such as ovulation inhibiting drugs and the postoperative state, are mentioned. Fibrinolysis was performed with streptokinase (awelysin) and urokinase (ukidan). In 11 patients streptokinase infusions therapy in ultra-high doses was carried out. Within 6 hours and 30 minutes the patients got 9.500,000 units of streptokinase. The complications of the streptokinase treatment are discussed. According to the age of the phlebothrombosis and the control phlebography 2 groups of patients were formed. In the first group including thromboses lasting for 1-6 days, 7 patients showed a complete recanalisation. In the second group including thromboses lasting for 1-3 weeks, only 4 patients developed complete recanalisation. The remaining patients had only a partial recanalisation. The post-lysis effect is stressed. Streptokinase therapy with ultra-high doses has become the standard procedure of fibrinolysis treatment in our hospital.
