Sex steroids and epidermal glands in two species of gekkonine lizards.
In vivo and in vitro experiments on the endocrine relationships of epidermal glands in the tokay Gekko gecko, and the common house gecko Hemidactylus bowringii are reported. The results show that certain aspects of beta-gland differentiation involve a synergistic action between androgens and those hormones responsible for controlling the normal shedding cycle, while other aspects are solely under androgenic control. Pre-anal organ activity appears to be solely under androgenic control.

Multiple localized root agenesis.
The cause of this condition is undetermined. Cessation of root development is associated with a variety of systemic, congenital or genetic disorders. External trauma, such as radiation and electrical burns, can arrest development.
