The comparative sensitivity of the male toad pregnancy test and the Friedman test.

چکیده
Comparative Series A series of 452 comparisons was made in this laboratory between the Galli Mainini pregnancy test, using the English male toad, Bufo bufo, and routine Friedman pregnancy tests. The latter were made in this laboratory by Dr. A. L. Taylor, and in the University of Bristol Department of Preventive Medicine by Professor K. E. Cooper. The series covered the period from March, 1950, to September, 1951, the majority of tests being done in the 12 months from July, 1950, to July, 1951. The technique used for the male toad test was that described by Klopper and Frank (1949). The toad was first catheterized, then 2 ml. of the patient's untreated urine was injected into the dorsal lymph sac. The toad was again catheterized after two hours, and, if no spermatozoa were seen in the urine, again after four hours. In the earlier tests two negative results up to a period of four hours were considered adequate; later the period was extended to six hours, but in all cases two negative examinations were required before a toad was reported negative. Results obtained with the 452 comparisons are shown in the Table. Further reports were obtained

Further experiences with the male-toad pregnancy test using European species.
The satisfactory reports on the Galli Mainini male toad test for pregnancy which have been published from nearly every part of the world (Cowie, 1948 ; Bhaduri, 1951) show that the test can be performed on species of toads or frogs indigenous to the district where the laboratory is situated. In England and Europe the toads Bufo bufo (syn. B. vulgaris) and B. calamita and the frog Rana esculenta...
