Abstract
Under study were catalase activity and indicators of lipid peroxidation (LP) of donor blood exposed to different doses of UV irradiation. Doses lower than 630 J/m2 were found to activate catalase and to inhibit LP while doses higher than 630 J/m2 inhibited catalase activity and activated LP. The indicators of LP have confirmed that therapeutic doses of UV-irradiated blood were nontoxic. The most optimal therapeutic dose of irradiation (630 J/m2) was determined.
摘要
研究了不同剂量紫外线照射下供血者血液的过氧化氢酶活性和脂质过氧化（LP）指标。发现低于630 J/m²的剂量可激活过氧化氢酶并抑制LP，而高于630 J/m²的剂量则抑制过氧化氢酶活性并激活LP。LP指标已证实紫外线照射血液的治疗剂量是无毒的。确定了最适宜的照射治疗剂量（630 J/m²）。
