[The effect of vasotocin, mesotocin and adrenaline on the interrenal gland in the frog Rana temporaria under in-vitro conditions].

: Morphometric studies indicate that vasotocin increases the activity of the adrenal gland in frogs, whereas mesotocin and epinephrine do not essentially affect it. Combination of epinephrine with nonapeptides in cultural medium showed that the former may abolish the effect of vasotocin on the adrenal gland.
