[Development of a bioassay from gonadal cellular cultures of the snail Helix aspersa: influence of nerve ganglion extracts on the synthetic activity of the target cells].

To realize bioassays a primary culture method was carried out with dissociated cells from the garden snail gonads. ADN and protein syntheses of gonadal cells were estimated using the liquid scintillation method. The gonadal cells were obtained from either adults of Petits Gris and Gros Gris, or young Gros Gris.
