On the activity of trifluoperazine and palmitoylcarnitine in mice: Delayed hypersensitivity models
2001
Abstract The effect of pre- and post-challenge treatments with trifluoperazine and palmitoylcarnitine, two protein kinase C (PKC) inhibitors characterised by their interaction with the phospholipid enzyme cofactor, on the inflammation caused by delayed hypersensitivity (DTH) to dinitrofluorobenzene (DNFB) and sheep red blood cells (SRBC) in mice is reported. The activity of dexamethasone and two immunosupressors, azathioprine and methotrexate, is also evaluated. The effectiveness of pre-treatment with each of the test drugs diminished when the DNFB challenge dose increased, whereas trifluoperazine and azathioprine were more active when administered after the challenge at the high DNFB dose.…
Effects of training on regional substrate oxidation in the hearts of ageing rats.
1989
23-month-old male rats were trained by running for 20 weeks. The oxidation rates of succinate, glutamate+malate, palmitoylcarnitine, and pyruvate and the activities of lactate dehydrogenase, citrate synthase, isocitrate dehydrogenase and cytochrome oxidase were measured in the subendocardium and subepicardium and in the right ventricle. Regional differences of substrate oxidation rates in the myocardium of old sedentary or trained rats were less than in young rats, suggesting that regional differences in the cardiac work load disappear during ageing. Training did not improve oxidation rates, in contradiction to some previous results.
Regional differences of substrate oxidation capacity in rat hearts: effects of extra load and endurance training.
1990
Male rats, aged 17 weeks at the end of experiments, were divided into four groups. Two groups lived in normal cage conditions with or without extra load (20% of the body weight) and two groups were trained by running with or without extra load for 8 weeks. Oxidation rates of succinate, glutamate + malate, palmitoylcarnitine, and pyruvate, and the activities of lactate dehydrogenase, citrate synthase, isocitrate dehydrogenase and cytochrome oxidase were measured in homogenates of the right ventricle and in those of the subendocardial and subepicardial layers of the left ventricle. Oxidation rates of succinate and palmitoylcarnitine tended to be higher in the subendocardium than in the subepi…
