title: [Lipid peroxidation and thrombocyte aggregation in vibration disease].
abstract: A three-fold increased level of malonic dialdehyde was found in platelets of patients suffering from the first stage of vibration disease, exposed to local vibration. The changes of the fermentative and nonfermentative lipid peroxidation (LPO) were: increased accumulation of malonic dialdehyde (by 2.5 times in ascorbate-dependent LPO and by 2.6 times in NADRH-dependent LPO). Patients with peripheral vasomotor dystonia of the upper limbs combined with vasomotor spasms of the fingers showed NADPH-dependent and ascorbate-dependent LPO respectively 41% and 29% more activated than in patients having no vasomotor spasms. In patient with vibration disease antioxidant activity was reduced by 39% on average, platelet aggregation, both spontaneous and induced by epinephrine, aggristine or adenosinediphosphoric acid, was increased. Platelet hyperaggregation in vibration disease may be caused by stimulated LPO in platelets, amassed end toxic product of LPO, decreased antioxidant activity.
