[The prevention of surgical stress in lung cancer patients with the antioxidant dibunol].

Dibunol was administered 48 and 24 hours before the operation at a dose of 4 g using capsules of 1 g each, in lung cancer patients. Stress severity was judged from the blood content of hydrocortisone, 17-keto- and 17-ketogenic steroids in 24-h urine, the content of mid-molecular weight peptides and indicators of intoxication before the operation and at 1, 3 and 5-7 day following it. Stress-protective effect of dibunol was manifested by almost 2-fold reduction in the blood hydrocortisone, urine 17-KS and 17-KGS/24 h levels following the operation, and by return of these parameters to baseline level at day 3 (whilst without dibunal no normalization occurred even at day 5-7), as well as by an appreciable lowering of the parameters characterizing intoxication.
