Sexual differences on thyroxin 5'-deiodinase (5'-D) in the Harderian gland of Syrian hamsters were investigated. We compared the 24-h profile of 5'-D activity in male and female hamsters, observing a clear rhythm in males but not in females. Female v

Syrian hamster Harderian glands show a typical sexual dimorphism, with males having two secretory cell types and females having one cell type and intraluminal porphyrin accretions, among other differences. Since these differences may be due to the ex

Background The Harderian gland (HG) is a tubulo-alveolar gland found within the ocular orbit of animals which present a nictitating membrane. The Harderian gland is regarded as an extrapineal melatonin producing organ and both, photoperiod and melato

It is known that the Harderian gland of male Syrian hamster synthesizes a much smaller amount of porphyrins than the gland of the female and that castration greatly increases this synthesis. We have studied in this experimental model the behavior of

The Syrian hamster Harderian gland has been advocated as a model to study the porphyrin biosynthetic pathway, since it shows by far the highest porphyrin concentration known to date. Another particular characteristic is the sexual dimorphism at both

This paper describes the influence of iron on both nuclear and cytosolic melatonin contents in several tissues of chicks. The neurohormone melatonin was estimated by means of radioimmunoassay. Iron, administered as FeCI3, decreased the nuclear melato

Pineal gland N-acetyltransferase (NAT) activity and pineal and serum levels of melatonin declined linearly in albino rats acutely exposed to different intensities of red light (600 nm or higher; low, 140 microW/cm2; moderate, 690 microW/cm2; high, 12

The Harderian glands of Syrian hamsters exhibit a marked sexual dimorphism in cell types and porphyrin production. The glands of male hamsters have two secretory cell types (Type I and II) while the glands of females consist of a single secretory cel

Background: The Harderian glands of female Syrian hamsters contain very high concentrations of protoporphyrin (in the range of μg per mg of tissue) which accumulate in the tubulo-alveoli of the gland. We have studied the process of synthesis, accumu
