Electric Correlates of the Menstrual Cycle in Women *
نویسنده
چکیده
In 1935, Burr and Musselman reported a correlation of the menstrual cycle in women with the difference in potential of the index fingers. Small daily fluctuations were noted. However, once in each cycle there occurred a marked increase in potential difference which was many times the usual determination. The right index finger showed an increase in positive polarity to several thousands of microvolts between the fourteenth and seventeenth days preceding the onset of the subsequent menses. For nine successive months this observation was repeated with great accuracy. A pregnancy record failed to show such cydic phenomena. A further study ( 1938) on a group of fourteen women showed that the voltage rises occurred most frequently in the middle of the cycle and some immediately after menstruation, but there were no unequivocal cases of peaks just preceding catamenia. There was evidence that cycles occur without the appearance of significant voltage rises. These findings have been confirmed by Parmenter.6 In the rabbit, sharp rises in potential differences between the vagina and symphysis had been demonstrated in association with ovulation by Burr, Hill, and Allen' and were confirmed by Reboul, Friedgood, and Davis.8 The marked variations in the electric potential between the index fingers in women and at the time of ovulation in the rabbit suggested that these phenomena are related. A continuous graph of the changes in electric gradients between the vagina and symphysis associated with ovulation in women was secured by Burr, Musselman, Barton, and Kelly.4 The voltage rise occurred nine days preceding the subsequent expected period. The electric surge was to the height of 100 millivolts, vagina positive. At laparotomy, the punctate hemorrhage of a ruptured follicle was

P-142: Adenosine Deaminase Activity during Menses, Follicular and Luteal Phases of Menstrual Cycle
Background: In recent years, numerous regulators of gonadal function have been studied. Adenosine deaminase(ADA) is widely distributed throughout human tissues and may contribute in the regulation of menstrual cycle. The purpose of this study was to determine the plasma activities of total adenosine deaminase (ADAT), and its isoenzymes, ADA1 and ADA2, and ADA1/ADA2 ratio during the menses, foll...
