Biometabolic effects of different nutrients on embryonal cultures.

It has been valued the effects of different nutrients (glucose, phospholipids and ethanol) on the growth and morphology of chicken embryo cells, cultured in vitro by "pendent drop". Considering that the basal nourishing substratum used in these studies is the best medium that may be supplied to the cultures for the growth of this kind of tissues, the entity of damage induced by different nutrients has been shown. It may be said that the less negative effect is induced by 2.5% ethanol and by the association: "glucose + 2.5% ethanol", that the damage induced by only glucose seems to improve in presence of 2.5% ethanol, that in presence of phospholipids the cells appear all full of big lipid drops (especially in the condition: "phospholipid + ethanol") and that 5% ethanol deeply appears to impair and alter the cultures, as it was been observed in our previous experiences.
