Abstract : Investigations were conducted to determine the role of the pineal gland in influencing the endocrine systems of hamsters, rats, mice, and gerbils. It is concluded that the gonadal involution in hamsters attendant upon darkness is prevented by pinealectomy or bilateral superior cervical ganglionectomy. Removal of the olfactory bulbs from adult female hamsters causes regression of the uteri; this response is also prevented by pineal removal. Darkness retards the development of the endocrine systems of albino rats but if the pineal gland is removed the endocrine organs develop at the normal rate. The pineal gland in mice and gerbils appears to play a less marked role in regulating endocrine organ size. (Author)
