Last Saturday morning he reported that the Japs, steadily being forced deeper into their pocket, had lost at least 300 dead (added to the campaign's total of about 5,000) in desperate rushes against one road block during the previous night. He added: "The battle is now at a critical stage...
...Hisaw thought a hormone in the ovaries might account for this change. He tested his theory by injecting extracts from a female's ovaries into castrated male pocket gophers. Sure enough, the males lost their symphyses...
Relaxin's discoverer is gentle, publicity-shy Professor Frederick Lee Hisaw, 52. He found the hormone during long, painstaking studies of the sex life of the pocket gopher, a small prairie animal that lives in burrows like a mole...
...researcher at Kansas State Agricultural College in the early '20s, Dr. Hisaw noticed a puzzling fact about the pocket gopher: the animal, for turning around in its narrow burrow, has a very narrow pelvis, and its compressed pubic bones come together in a bridge (called the symphysis), which leaves an opening much too small for the female to deliver her young. But when a female becomes pregnant, the symphysis somehow dissolves, the opening widens...
When Dr. Hisaw published these findings under the title, "The Influence of the Ovary on the Resorption of the Pubic Bones of the Pocket Gopher," nobody paid much attention. But endocrinologists began to get interested when Dr. Hisaw and fellow researchers found the relaxing substance in the blood of pregnant guinea pigs, rabbits, sows, dogs, cats, mares, women. In non-burrowing animals, relaxin dissolved no bone (as in the pocket gopher) but relaxed the pelvic ligaments and widened the pelvic canal, thus making birth easier. Hisaw found that even virgin female animals were relaxed by relaxin...
