Abstract

Treatment of rats with noradrenaline stimulated $H_20_2$ generation in liver mitochondria using succinate, choline or glycerol 1-phosphate as substrate. The dehydrogenase activity with either succinate or choline as substrate showed no change, whereas that with glycerol 1-phosphate increased. 2. The effect was obtained with noradrenaline, but not with dihydroxyphenylserine. 3. Phenoxybenzamine and yohimbine, but not propranolol, prevented the response to noradrenaline treatment. 4. Phenylephrine could stimulate $H_20_2$ generation, whereas isoprenaline had only a marginal effect. 5. Theophylline treatment slightly decreased the generation of $H_20_2$ in liver mitochondria, but treatment with pargyline, Ro4-1284 and dibutyryl cyclic AMP had little effect. 6. These studies showed that noradrenaline might possibly be acting through the $\alpha_2$-adrenergic system.
