Studies of the suprarenal glands of dogs. I. Comparison of the weights of suprarenal glands of mature and immature male and female dogs

Abstract

There is much evidence that points toward an intimate relationship between the suprarenal glands aiid the various phases of reproduction iii rodents but such a relatioriship has not been reported for dogs. There are reports of changes in the weights of the suprarenals with relation to sex and phases of the oestrous cycle in rats, guinea pigs, rabbits, pigeons, cats and moles.Elliott arid Tuckett ('06) noted that the suprarenals of the rat, cat, guinea pig and rabbit develop equally in each sex until the time of reproduction. Growth after early youth was of cortex alone. After the animals were mature the glands of the female were larger than those of the male. The increase in the size of the gland in the female was of medulla as well as of cortex. The right gland was almost invariably heavier than the left in the several different animals studied. Weights of the suprarenal glands from seven dogs were given. Fonr of these were listed as young animals hut the maturity of the other three was not statecl.Rogoff and Stewart ('27) reported the weights of the sirpra-1-enal glands of several dogs in coiinection with some work 0x1 the survival period after suprarenalectomy during pregnancy. They did not study the relation of the weights of the glands to the different sexes. Pianese ('29) studied the changes in the snprarenals of three castrated male and the same number

Genetic Variation in Adrenal Weight in Young Adult Mice

“…Hatai, 1914;Baker, 1937) and in mice (Chester Jones, 1948Jones, , 1955. However, it is interesting to note that the magnitude of the sex difference was strain-dependent.…”

“…Sexual dimorphism of the adrenal weights was first noted by Hatai (1914) in rats. Baker (1937) found similar sex differences in guinea-pigs and subsequent studies on other mammals have shown that sexual dimorphism in adrenal weight is common.…”
