BACKGROUND: According to the areas and people that are examined, there are many differences in the prevalence of syphilis in Korea. However, the reactive rate of the serologi test for syphilis showed an increase in the 1960s, and it has deerea@sed from the beginning of the 1970s. OBJECTIVE: Comparing the results of tke serologic test for syphilis which lotad been performed for the 5 years(1987-1991) on the physical examines and pregnant women who were considered as healthy, with the results with normal people, who were considered as healthy, which had been already reported, we tried to observe the change of reactive rate of serologic test for syphili. METHODS: The serologic test for syphilis, including serum VDRL test and serum TPHA test, were carried out on 25,254 healthy adults(20,405 were physical examineea eamined at National Medical Center and 4,849 were pregnant women delivered at National Medical Cer ter). RESULTS: The reaetive rate of serum VDRL test was 0.8% in 25,25 the althy adults(physical examinees 0.8%, pregnant women 0.7%). There were no stistically differerces between the annual incidences. 85.5% of VDRL-reactive subjects showed low VDRL titers(below 1:4) by the quantitative serum VDRL test, The biologic false positive reaction of serum VDRL test was 29(19.5%) in 149 VDRL-reactive subjects, using serum TPHA test as a standard. CONCLUSION: This study suggested thai, there was a decrease in the prevslence of syphilis in Korea.

A rate com;lication of hysterectomy is complete prolapse and inversion of vagina. This can occur whether the hysterectomy was abdominal or vaginal and cystocele and/or enterocele is often associated with this condition. Traditionally, prolapse has been treated by surgery, the types of operation for prolapse are generally but not always, carried out through the vaginal rather than through the abdominal surgical route. We experienced five cases who had repair of posthysterectomy vaginal vault prolapse by transabdominal sacral colpopexy and report with brief review of literatures.

To investigate the nature of artifacts caused by air and chemical shift by fat, a test tube phantom study was performed in 2.0T and 0.5T superconducting magnetic resonance imaging systems in various imaging sequences. Spatial mismapping and signal change made image distortion in spin echo images of the air-column and severe signal voids in gradient echo images. Chemical shift artifacts appeared in the planes of frequency-encoding axis as crescent-shaped signal voids and summated bright signals, Both artifacts were more prominent in high field strength, Images at 0.5T showed more severe artifacts in the T2-weighted images than those in the other sequences. As the acquisition matrix increased, truncation artifacts decreased and susceptibility artifacts in gradient echo images diminished. Familiarity with causes, appearances and mechanisms of various artifacts will help radiologists for interpretation of MRI.

OBJECTIVES: Polycystic ovary syndrome (PCOS) has the feature of excessive LH, hyperandrogenism and disturbance of folliculogenesis. Also, insulin, IGF-I and IGFBP-1 are involved in the pathogenesis of PCOS. Various surgical and medical therapies have been used and the action mechanisms are related to the endocrine effect. Laparoscopic ovarian electrocautery or laser vaporization is effective in the restoration of ovulation and normal menstrual cycle with minimal invasive procedure especially in the patients resistant to medical therapy. Clomiphen citrate (CC) is used for the ovulation induction in PCOS and the resistance is known to be related to insulin, IGF-I, IGFBP-1 levels. This study was performed to evaluate the effect of the laparoscopic laser vaporization on the levels of LH, FSH, testosterone, IGF-I and IGFBP-1 and on the ovarian response to clomiphen citrate in patients with CC-resistant PCOS. MATERIALS AND METHODS: The fasting basal serum LH, FSH, testosterone, IGF-I and IGFBP-1 level were measured in 10 PCOS patients with CC-resistance and 7 normal controls with regular menstrual cycle. In PCOS, after laparoscopic CO2 laser vaporization, endocrine levels were measured in 1 week interval for 4 weeks and then compared with preoperative levels. RESULTS: In PCOS group, mean serum LH/FSH ratio, testosterone, IGF-I levels were higher and IGFBP-1 level was lower than control. LH/FSH ratio decreased from 2.51+/-0.67 to 1.7+/-0.6 (p<0.05) in 2 weeks, to 0.56+/-0.2 (p<0.01) in 3 weeks and to 1.41+/-0.3 (p<0.01) in 4 weeks after operation. Testosterone level decreased from 1.51+/-0.82 ng/ml to 0.65+/-0.34 ng/ml (p<0.05) in 2 weeks, to 0.56+/-0.67 ng/ml (p<0.01) in 3 weeks after operation. IGF-I level also decreased from 436+/-47.5 microgram/l to 187+/-38 microgram/l (p<0.01) in 1 week, to 167+/-42 microgram/l (p<0.01) in 2 weeks, 179+/-55 microgram/l (p<0.01) in 3 weeks and to 120 +/-43 microgram/l (p<0.01) in 4 weeks after operation. IGFBP-1 level showed no significant change. In 8 of 10 PCOS patients, ovulation was induced with low dose clomiphen citrate. CONCLUSION: Laparoscopic CO2 laser vaporization restores normal menstrual cycle and ovulation through endocrine effect of decreasing LH/FSH ratio, testosterone and IGF-I level and increases the response to CC. Therefore it is useful for restoration of normal menstruation and induction of ovulation in CC resistant PCOS patients.
