Abstract:
PURPOSE: A method for quantitatively analyzing androgen in a biological specimen is provided to obtain data for evaluating alopecia medicine based on the concentration distribution of the androgen. CONSTITUTION: Androgen substituted with isotope as an internal standard material is added into a biological specimen. The androgen is extracted from the biological specimen using a copolymer absorbent with hydrophilic property and lipophilic property. The extracts is re-extracted using an organic solvent under pH 8 to 12. The re-extract is derivatized into flophemesyl-trimethylsilyl. The androgen is selectively detected by a gas chromatography-mass spectrometry. The biological specimen is urine or blood.

Abstract:
PURPOSE: A marker for diagnosing pelvic organ prolapse containing glycine is provided to sense pelvic organ prolapse occurrence by measuring glycine concentration in urine sample. CONSTITUTION: A marker for diagnosing pelvic organ prolapsed contains glycine. The marker is glycine in urine. In case of containing less than 70% of glycine concentration in urine, pelvic organ prolapse can be caused. The glycine concentration is measured using capillary electrophoresis-mass spectrometry(CE-MS). A method for diagnosing pelvic organ prolapse comprises: a step of collecting urine sample from a patient; a step of solidifying and filtering protein in urine sample to remove; a step of injecting CE-MS to qualify glycine concentration.
