[A neuropharmacological study of isoteolin (IST)].
|
| Abstract |
Neuropharmacological study of IST was carried out on mice and rats, using the so-called practically "blind" neuropharmacological screening of M. Nikolova and L. Daleva (1968). The investigated product IST was administered under the form of 0.1-1% of solutions prepared ex tempore with saline in doses, equivalent to 1/440-1/250 to 1/2-4 1/2-4/5 of LD50. The studies on behaviour profile of mice and rats showed that IST induced symptoms of increasing inhibition of the central nervous system (CNS) in conformity with an increase in the dosage. It was established that IST inhibited dose-dependent spontaneous and stimulated with amphetamine motor activity and orientation reaction of mice, antagonized group amphetamine toxicity and excitatory effects of amphetamine as well as of morphine on mice; potentiated hexobarbital narcosis of mice and rats; lowered body temperature of rats; elevated the threshold of pentetrazolic seizures. In very high doses (50, 100 and 200 mg/kg i.p.), equivalent to 1/5 to 2/3 of LD50 IST induced excitatory effects on central and peripheral nervous system-provoked unaddressed aggressiveness, salivation, increased frequent breathing and chromodacryorrhea [correction of chromodacriurea]. The obtained experimental results show that IST manifest central depressive effect and has mainly neuroleptic character in respect to CNS.
