The sex cord tumor with annular tubules is a rare ovarian neoplasm the predominant component of which has morphologic features intermediate between those of the granulosa cell tumor and those of the Sertoli cell tumor; focal differentiation into either granulosa cell or Sertoli cell tumor may occur. It is microscopically characterized by the formation of simple and complex annular tubules with hyaline bodies and it occurs often in patients with Peutz-Jeghers syndrome. Recently author experienced a case of ovarian sex cord tumor with annular tubules in a 49 year old female without Peutz-Jeghers syndrome. Clinical data and histopathological findings of the case were discussed and a brief review of the literature on this entity, especially the relationship to Peutz-Jeghers syndrome and the pathological differences between the tumor associated with and without Peutz-Jeghers syndrome.

Various parameters obtainable from the M-mode echocardiograms were determined in 100 healthy young males, and a comparative study of the data with those of the previously reported was made. It was found that our data as a whole were in general agreement with the others.

BACKGROUND: The use of anesthesia during assisted reproductive technology (ART) such as TEST (Tubal Embryo Stage Transfer) may expose early embryo to anesthetics in tubal fluid. The effects of anesthetic agents on the development of early embryo in ART are yet unclear. The purpose of this study was to evaluate the effects of narcotics on mouse two-cell embryo development using in vitro growth model of mouse embryo. METHODS: Mouse two-cell embryos were exposed to narcotics, fentanyl (6.0 nM; 30.0 nM) and meperidine (1.0 M; 3.6 M) respectively. Mouse two-cell embryos unexposed to any drugs were served as controls. In vitro developmental patterns were observed on the third and fifth day of culture. RESULTS: There were no significant differences in the rates of embryos arrested at 2~8 cell stage on the third day after culture and blastocysts development and their hatching on the fifth day after culture among three groups. CONCLUSION: We conclude that fentanyl and meperidine in clinical therapeutic concentration have no detrimental effects on the in vitro two-cell mouse embryo development. But further investigations are required to determine whether narcotics have any adverse toxic effects in human reproductive medicine.

Differences in systolic time intervals(STI's) attributable to the types of mechanocardiographs used for their determinations were studied in a total of 341 healthy adult males. The STI's were measured from mechanocardiograms consisting of simultaneously rocorded electrocardiograms, phonocardiograms and carotid arterial pulse tracings obtained by each of three different types of mechanocardiographs in 125, 56 and 160 subjects, respectively. The study revealed that there were slight to considerabe differences among the three groups in the correlation coefficients between the individual STI's and heart rate. Thus, regression equations using heart rate as variables, for those STI's which were significantly correlated with heart rate, differed slightly to considerably among these groups. In addition, the mean values of those STI's and their derivatives, which showed no significant correlation with heart rate, were also silghtly or significantly different among the three groups. These findings suggest that if STI's obtained from patients are to be adequately evaluated at all, each laboratory must define its own normal standards worked out by using its own methods of recording and analysis of the mechanocardiogram, and cannot rely on those proposed by others.
