RESUMEN
<p><b>OBJECT</b>To study the significance of the ultra-high power microscope in the examination of vaginal discharge.</p><p><b>METHODS</b>By the ACT-2000 ultra-high power microscope system and Olympus CX21 microscope, the vaginal discharge of 1,100 gynaecology out-patients was examined respectively.</p><p><b>RESULTS</b>The positive rate of mould in the patients was 11.55% by CX21 and was 20.27% by ACT-2000, respectively. The positive rate of trichomonas vaginalis was 2.55% by CX21 and 3.0% by ACT-2000, respectively. The clue cell was detected in 11.27% of the patients by ACT-2000, but no such cell reported by CX21. Totally, positive results were obtained in 14.09% of the patients by CX21 and 32.55% by ACT-2000.</p><p><b>CONCLUSION</b>By using the ultra-high power microscope, the positive result can be increased obviously in the examination of vaginal discharge. It is very important in clinical practices.</p>
