Secretin attenuates the hereditary repetitive hyperactive movements in a mouse model
It was previously demonstrated that secretin influenced the behavior of rats investigated by open-field test.

| Tartalmi kivonat: | It was previously demonstrated that secretin influenced the behavior of rats investigated by open-field test. In the present experiment, we have compared the effect of intracerebroventricular administration of 2 mug of secretin on the behavior of CFLP white and Japanese waltzing mice. These latter animals exhibit stereotypic circular movements. The effect of secretin on the horizontal (ambulation) and vertical movements (rearing and jumping) was investigated in open-field test. The ambulation time and distance were shorter, and the number of rearing and jumping were much lower in Japanese waltzing mice than in CFLP white mice during 30 min-experimental period. In white mice, 2 mug of secretin had no effect on the above-mentioned parameters; however, in Japanese waltzing mice, secretin enhanced the ambulation time and distance to the level of CFLP white mice, but did not influence the rearing and jumping. On the basis of the results, it was concluded that intracerebroventricularly administered secretin attenuated the stereotypic (circulating) movement and improved the horizontal movement indicated by the normalization of the ambulation time and distance; however, it did not influence the explorative behavior (rearing and jumping) in our special animal model. |
