title: [Effect of bromantane on the rat neurologic status in two month course].
abstract: The oral administration of bromantan for two months on a toxic dose level produced a sex-dependent psychodysleptic action upon rats: the effective (30 mg/kg), intermediate (150 mg/kg), and toxic (600 mg/kg) doses reduced the motor activity in males, while not affecting (or increasing) this activity in females. The effective dose stimulated, and the toxic dose suppressed, the research activity and increased the number of grooming episodes, while ambiguously influencing the emotional state of rats. In the initial stage of treatment, bromantan causes hypothermia; in the second month, this effect is replaced by slight hyperthermia. Prolonged administration of a large dose of bromantan oppressed food uptake and slightly increased drink uptake. Upon the bromantan treatment, the body weight increased in females and decreased in males. The bromantan treatment course increased the muscle strength of rats; the operant activity was optimized during the first month of the course. The general physiological and behavioral characteristics of animals restored within two months after termination of the treatment course. During this period, the test animals exhibited no significant behavioral symptoms indicative of the drug dependence. The two-month treatment did not lead to the development of tolerance with respect to the optimizing drug action upon the physical and operant capacity.
