Manhattan Obstetrician Raphael Kurzrok believes that a large number of miscarriages are caused by "genital hypoplasia" (malformation plus deficient hormone activity). His analysis: in some women, because of insufficient output of estrogen (a female hormone) during pregnancy, expansion of the uterus fails to keep pace with growth of the fetus. Rupture of the membrane and miscarriage result...
Trial Rabbits. The Harvard experiments are a development from similar work on rabbits by Biologist Gregory Pincus at Clark University (TIME, March 12, 1934). Dr. Pincus, after fertilizing rabbits' eggs with sperm in glass, planted the resulting cells in a female rabbit's uterus and she bore normal, healthy bunnies.* Other investigators have nursed a monkey's egg, fertilized in its mother's body, to the eight-cell stage in glass. Six years ago Philadelphia's Cancer Specialist Stanley Philip Reimann, by pricking a human ovum with a glass needle, succeeded in stimulating...
...method is called paravertebral sympathetic nerve block. It is sponsored by Dr. Shiras ("Skipper") Jarvis of the University, who is now somewhere in the Pacific with the Navy. Procedure: wait until labor pains are seven minutes apart then block the nerves which conduct pain from the uterus to the brain. This is done by inserting a needle beside the lower spine and injecting a local anesthetic (usually procaine, a cocaine substitute) into the nerve channel which serves the uterus. As labor progresses, nerves farther down are blocked and finally the mother, who until then has been fully conscious...
...natal influence was in the news last week. At Los Angeles City College, Psychologists Johnette Dispense and Richard T. Hornbeck injected small doses of electrical current in the uterus of female rats, then tested the maze-running intelligence of their offspring against that of undosed rats with the same fathers. Result: when a mother rat got a dose of one milliampere from the cathode (negative pole), the odds were 383-to-1 that her litter would be superior in intelligence; a dose of two milliamperes had the opposite effect-the litter was inferior (61-to-1). Doses from the anode...
...About 60% of women with cancer of the uterus or breast have a hard, raised bony protuberance where the hard palate joins the soft palate...
