Abstract

Certain endocrinological characteristics of granulosa cell tumors (GCT) in two Japanese Black cows were described. The ages and parity of the two cows were 12 years old and 9, and 4 years old and 2. Plasma samples were taken from the jugular vein from 213 to 170 days prior to the surgical removal of the affected ovaries with GCT and from nine days prior to the removal to ten days after the removal in Case A, and from 85 days prior to two days after the removal of the affected ovary in Case B. Plasma concentrations of estradio1-17β, progesterone, testosterone, inhibin and follicle-stimulating hormone (FSH) were measured by radioimmunoassay. The two cases showed no distinct estrous sign or abnormal estrous behavior. Plasma concentrations of inhibin remained high before the ovarian removal, and declined abruptly after the removal in the two cases. In contrast, plasma concentrations of FSH increased after surgery. In conclusion, it is suggested that inhibin secreted from the ovary of a cow with GCT may be biologically active, and that the elevation of plasma concentration of inhibin could be a useful indicator for the diagnosis of bovine GCT.
