[The phasic contraction of the guinea pig vas deferens in organotypic culture during periodic stretching].

Vas deferens explants from the adult guinea pigs were cultivated under organotypic conditions with repeated stretching. In control explants with no stretching over 9 days the occurring hypersensitivity is similar to the denervated one. Simultaneously phase component contractile response decreased in a 5.

[The hypersensitivity of the guinea pig vas deferens in organotypic culture under static stretching].

The explants of the guinea pig vas deferens acquired the same hypersensitivity as the denervated ones in cultivation under organotypic conditions. The hypersensitivity reached its maximum in 9 days. The explants cultivated with static stretching during 9 and 15 days preserved the contractile properties of freshly isolated stria.
