Purpose： The purpose of this study was to identify cerebral cortices related with sexual arousal fro visual sexual stimulation in healthy males using BOLD-based functional MR imaging Method： Sixteen male volunteers with sexually potent(mean age：24) were examined for thi study. Functional MRI was performed on a 1.5T MR scanner(GE Signa Horizon) with birdcage-type head coil. In this study, blood oxygenation level dependent(BOLD) technique was utilized to create fMR image reflecting local brain activities. The BOLD-based fMRI d were obtained from 7 oblique planes using gradient-echo EPI with $90^{\circ}$flip angle, 50ms TE 6000ms TR, $26cm{\times}26$ cm FOV, $128{\times}128$ matrix, and 10mm slice thickness. The sexual stimulation paradigm consisted of two alternating periods of rest and activati and it began with a 1 minute rest, followed by a 2 minute stimulation by a documentary a erotic video film. Brain activation maps were generated by cross-correlation of imag acquired during rest and activation periods. The index of activation was used to compare t number of pixels activated by each task in each volunteer, where the significance of th differences was evaluated by using Students t-test.

Objective: To determine the cutoff value of clomiphene citrate challenge test(CCCT) that can predict the normal and abnormal(diminished) ovarian response group and to assess the usefulness of CCCT as a predictor of ovarian reserve. Materials and Methods: From March 1994 to Februry 1996, CCCT was performed to 129 infertile patients and among them, 20 patients whose basal FSH on the third day of menstrual cycle was more than 20 mIU/ml were excluded. At the same time, the same CCCT was performed to the fifteen healthy volunteers with proven fertility to determine the cutoff value of CCCT. Results; 1) A FSH value higher than 23.4 mIU/ml, measured on the 10th day of menstrual cycle, was defined as a abnormal ovarian response. The cutoff value of 23.4 mIU/ml is more than 2 standard deviations(SD) above the mean value of 15 healthy women after CCCT. 2) The abnormal CCCT group, the subpopulation with a FSH value of 23.4 mIU/ml or more, was 7.3%(8/109) and their mean age was higher than the normal CCCT group($36.5{\pm}4.5$ vs. $32.9{\pm}4.8$, P = 0.059). And the percentage of the patients older than 35 years of the abnormal CCCT group was significantly higher than that of the normal CCCT group(62.5% vs. 38.6%, p <0.05). 3) There was no correlation between the hormone values of the third day and the 10th day of menstrual cycle before and after CCCT except between FSH of the third day and the 10th day. Conclusion: The CCCT is a good method to predict the individual ovarian response to COH for ART, especially in the patients who has no other abnormal findings that predict poor prognosis. And it is neccessary to determine the cutoff value of CCCT by the large numbers of randomized study, and combining the previously proven prognostic factors, it can be applicated in many individual centers for evaluate the ovarian response before ART program.

Glimepiride, a third generation sulfonylurea, is an antihyperglycemic agent widely used to treat type 2 diabetes mellitus. In this study, an untargeted urinary metabolomic analysis was performed to identify endogenous metabolites affected by glimepiride administration. Urine samples of twelve healthy male volunteers were collected before and after administration of 2 mg glimepiride. These samples were analyzed by liquid chromatography-tandem mass spectrometry (LC-MS/MS), and then subjected to multivariate data analysis including principal component analysis and orthogonal partial least squares discriminant analysis. Through this metabolomic profiling, we identified several endogenous metabolites such as adenosine 3', 5'-cyclic monophosphate (cAMP), quercetin, tyramine, and urocanic acid, which exhibit significant metabolomic changes between pre- and posturine samples. Among these, cAMP, which is known to be related to insulin secretion, was the most significantly altered metabolite following glimepiride administration. In addition, the pathway analysis showed that purine, tyrosine, and histidine metabolism was affected by pharmacological responses to glimepiride. Together, the results suggest that the pharmacometabolomic approach, based on LC-MS/MS, is useful in understanding the alterations in biochemical pathways associated with glimepiride action.
