The effect of luteineizing hormone on chicken testis and pineal gland uptake of 32P.
The glandular uptake of radioactive phosphorus (32P), administered carrier-free, was used as an endpoint for the study of the effects of luteinizing hormone (LH) on the testis and pineal gland of 3-, 10- and 13-day-old White Leghorn cockerels. Pineal uptake of 32P of the 13-day-old birds decreased and testis uptake of 32P increased following LH treatment. Maximum effects were observed when 20 mug LH was administered 4.0 h before autopsy. Although testis uptake of 32P increased following LH treatment in 3- and 10-day-old cockerels, pineal uptake of 32P remained unchanged.
