SummaryMonoamine oxidase (MAO) and alcohol dehydrogenase (AD) activities were studied histochemically in the Syrian hamster Harderian gland using tryptamine as substrate and Nitroblue Tetrazolium as the final electron acceptor. No dark: light-related changes were observed. Male type I secretory cells showed an intense MAO reaction. Female type I cells exhibited a moderate MAO activity. Both male and female glands showed a moderate/intense AD-positive reaction. Male type II cells were lacking…

THE HISTOCHEMICAL DEMONSTRATION OF MONOAMINE OXIDASE ACTIVITY BY TETRAZOLIUM SALTS
TLDR
Localization of the formazan to autonomic ganglia and fibers, chief cells of the gastric fundus, mucosal epithelium of the duodenum and certain specific zones of the renal tubules by means of the tryptamine-tetrazolium technique was confirmed as indicating monoamine oxidase activity by identical localization using the hydrazone precipitation technique of Koelle and Valk.
PROPERTIES OF MONOAMINE OXIDASES IN SYMPATHETIC NERVE AND PINEAL GLAND
TLDR
The results are consistent with the view that there may be multiple forms of MAO and that these forms may be associated with specific cell types.
Histochemical localization of monoamine oxidase in whole-body, freeze-dried sections of mice
TLDR
This enzyme system does not appear to produce the proximal carcinogen from this nitrosamine, and this staining technique should be useful in further studies on the identification of the multiple forms of monoamine oxidase in tissues of the mouse.
Androgenic control of the harderian gland in the male golden hamster.
TLDR
The potencies of the various androgens in maintaining normal Harderian gland morphology and activity are compared with their effects on other somatic variables and sexual behaviour.
Sexual Dimorphism in N-Acetyltransferase Activity, Hydroxyindole-O-methyltransferase Activity, and Melatonin Content in the Harderian Gland of Syrian Hamsters: Changes following Gonadectomy 1
TLDR
Intact male hamsters had very low levels of Harderian HIOMT activity and melatonin content in comparison with the glands of the females, and testosterone implants in the castrated males led to a recovery of the original male NAT levels.

TLDR
The findings indicate that criteria for MAO-A, -B, and other subgroups must be defined for each species and tissue.
Fine structure of the hamster harderian gland
TLDR
The Harderian gland from 4-week-old female hamsters is speckled with a black-brown pigment, whereas it is not pigmented in the male, and most cells of the gland from the male have large vaculoles, in contrast to the smaller vacuoles of the female.
Influence of some endocrine glands, hormones and blinding on the histology and porphyrins of the Harderian glands of golden hamsters.
TLDR
Glands from both male and female animals showed abundant cytoplasmic lipids and pigment formation appeared to be endogenous and in some cases occurred by extrusion of cells from alveolar walls and their subsequent transformation.
