A new model of an experimental depressive syndrome in rats induced by the systemic administration to the animals of 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine


, : A new model of an experimental depressive syndrome in rats induced by the systemic administration to the animals of 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine. Zhurnal Vysshei Nervnoi Deiatelnosti Imeni i P Pavlova 45(2): 377-387

Dynamics of appearance and maintenance of emotional-behavioural disorders in male Wistar rats was studied on and after repeated neurotoxin MPTP injection at a dose of 15 mg/kg intraperitoneally daily for 18 days MPTP caused suppression of locomotion and rearing in open field test, decrease of daily liquid consumption and lowering of preference for the sucrose over water, increase of immobility time and depression index simultaneously with disadaptation in forced swimming test. Behavioural alterations were maintained for not less than a week after abolition of MPTP injection. Data improved the appearance and development of the state of decreased motivation simultaneously with anhedonia and behavioural despair in rats in response to MPTP injection. The state can be considered as a new model of DA-depended depression-like syndrome in rats.

Surveillance of hospitalized cholera cases from 1970 to 1977 in Dhaka, a matched control study in 1974 and a neighborhood control study in 1975 were carried out and show a change from classic cholera to the eltor biotype during this period. Of all...

Three trials were carried out on sheep-grazed white clover/grass pasture. Different areas were ungrazed, lightly grazed or hard grazed and half the area was boom-sprayed with 1 kg 2,4-D ester/ha. Both hard grazing treatments and 2,4-D reduced the...

Cerium as a trace element in the periodic table is a member of the lanthanide group. Cerium ionic radius and its binding properties are similar to ferric ions, which may be bound to transferrin. So it can be considered as a competitive element to...
