Popis: | For use as assay animals male chicks have the advantage of being relatively cheap and usually available. Moreover, they require a minimum of care and the equipment used is inexpensive. Quantitative measurement of the sensitivity of the chick testis to gonadotropic hormone will make possible its use in assays of gonadotropic potency. The reports of numerous investigators have shown that the chick testis responds to administered gonadotropic hormone from various sources by rapid weight increase. The response to hormone from pituitary preparations and pregnant mare serum is known to be greater than that to hormone from pregnancy urine preparations. Asmundson, Gunn and Klose (1) and Breneman (2) have made recent reports of a qualitative nature, and these papers may be consulted for references to previous work. |
