[Effect of various anti-inflammatory agents on the stability of lysosomes and peroxisomes and total catalase and acid phosphatase activity]. / Vliianie nekotorykh protivovospalitel'nykh preparatov na stabil'nost' lizosom i peroksisom pochek i na obshchuiu aktivnost' katalazy i kisloi fosfatazy.

An increased permeability of kidney lysosomes from indomethacin and cortisone treated rats was found. Aspirin did not induce any changes in the rate of unmasking of latent acid phosphatase. This drug decreased the nonsedimentable catalase activity in kidney homogenates thus indicating an enhanced mechanical resistance of peroxisomes. Antiinflammatory drugs examined were shown to inhibit total catalase activity well expressed only after cortisone administration.

[Lipid peroxidation in the muscles of various animals]. / Prekisno okisliavane na lipidite v muskuli pri razlichni zivotni.

The dynamics of cumulation was followed up of the products of peroxide oxidation of lipids (POL) during the storage of meat obtained from broiler birds, pigs, and calves, and the activity was determined of one of the systems responsible for the deposition of such products--the nonenzyme system. Results showed that the cumulation of POL products in sampled white poultry meat and meat of pigs and calves, stored for 20 days at -5 degrees to -10 degrees C had close values. The rate of deposition in red poultry meat appeared to be several times higher. Investigations into the activity of the nonenzyme system that produced catalytic effects with POL 4 to 5 hours after sampling the meat revealed that it was lowest in homogenates of calf meat, and it was highest in homogenates of poultry meat, especially of red poultry meat. In this respect the meat of pigs ranked second. The data of the two criteria used showed that the rate of POL in PSE meat was lower than in normal meat of pigs.
