Abstract
Forty eight male rats weighing 140--170gm were
injected intravenously with 1 to 30 mg of human
chorionic gonadotropin. The localization of this
hormone within 5 minutes to 24 hours after injection
was carried out immunohistochernically using the
specific rabbit anti-human chorionic gonadotropin
and sheep anti-rabbit gamma globulin labeled with
horseradish peroxidase followed by enzyme staining
and then was examined under the ordinary light
microscope.
The most frequent and intense reaction sites were
the cells of Leydig of the testis, epithelial cells of
ductus epididymis, and ductus deferens. Some localization
of hormone was also observed in the tunica
albuginea of the testis, macrophages of the mesenteric
lymph node, and Kupffer cells of the liver. No
positive reactions were observed in the thyroid gland
and the kidney. In the pituitary gland, endogenous
luteinizing hormone which is known as having specific
cross reaction with the anti-human chorionic
gonadotropin was localized intensely both in the
experimental and control group of rats.
Positive reaction was appeared weakly 15 minutes
after injection of hormone and was reached to maximum
intensity 60 minutes after injection, therafter
intensities were reduced gradually.
We failed to localize HCG in the rats which were injected 1 mg and 5 mg of hormone respectively.
Contol group of rats did not reveal any positive reaction site except the luteinizing hormone granules
of the pituitary glands.
