The development of free radical processes in experimental bronchospasm. Effect of the bronchodilator preparation troventol

The development of bronchospasm is shown to be accompanied by lipid peroxidation (LPO) activation; 3-fold and 8-fold rises of malondialdehyde concentration are found in homogenate of lung from sensitized animals and from animals provoked with egg albumin antigen, respectively. The use of luminol-dependent chemiluminescence (CL) reveals that in sensitized rats the production of oxygen free radicals is increased by alveolar macrophages activated with phorbol myristate acetate. Troventol at 10⁻³ mg/ml inhibits the CL response of phagocytes both in intact and in sensitized rats and lowers the level of Fe²⁺-induced LPO in lung tissue but not in the liver of intact animals.

Phospholipid spectrum and lipid peroxidation in cell membranes of brain tissue in thymectomized rats

Lipid peroxidation (LPO) processes and the phospholipid (PL) content and composition in the homogenate and in the mitochondrial and supramitochondrial compartments of brain cells of adult male rats were studied 3 and 6 months after thymectomy. Thymectomy was found to markedly increase the rate of LPO and to reduce antiradical activity in all cellular compartments. A reliable increase of the level of total phospholipids in the homogenate and mitochondria was observed by the third month after thymectomy and a reduction of its control levels during the sixth month postoperation. On the other hand, a reduction of the content of total phospholipids was observed in the supramitochondrial fraction by the sixth month of the experiment. An increase of the phosphatidylethanolamine (PE) and phosphatidylserine (PS) contents was found to be mainly responsible for the changes in the level of total phospholipids.
