목적 : 무증상 세균뇨와 무균농뇨의 원인을 생리적 포경에서 찾아보고 스테로이드 국소치료와 포피 위생이 무증상 세균뇨와 무균농뇨의 소실에 미치는 치료 효과를 평가하고자 하였다. 방법 : 2004년 1월부터 2007년 12월까지 무증상 세균뇨와 무균농뇨가 확인된 90명의 남아에서 포피의 견인도에 따라 생리적 포경을 비견인 포피와 견인 포피로 구분하였고 포피 위생 여부를 확인하였다. 비견인 포피군(n=59)에서는 스테로이드 국소 치료(hydrocortisone 0.1% 크림 국소도포와 견인, 3회/일) 와 포피 위생 교육을, 견인 포피군(n=31)에서는 포피 위생 교육을 시행하였다. 포피 국소치료 2-4주 후 포피의 견인도를 재평가하였고 소변검사를 시행하여 무증상 세균뇨와 무균농뇨의 소실 정도를 평가하였다. 결과 : 무증상 세균뇨와 무균농뇨를 보인 남아의 65.6%에서 비견인 포피가 관찰되었고 대상아 모두(100%)에서 포피 위생을 시행하지 않았었다. 비견인 포피군(n=59)에서 스테로이드 국소 치료 후에 48명(81.4%)에서 견인 포피로 호전되었다. 견인포피로 전환된 경우(n=48), 무증상 세균뇨와 무균농뇨는 77.1%에서 소실, 18.7%에서 감소, 4.2%에서 지속되었고 이는 비견인 포피가 지속된 경우(n=11)의 18.2%, 27.3%, 54.5%에 비하여 유의하게 호전되었다(P=0.0014). 견인포피군(n=31)에서는 포피 위생에 순응한 경우(n=23)에 무증상 세균뇨/무균성 농뇨가 65.2%에서 소실, 26.0%에서 감소, 8.2%에서 지속되어 포피 위생에 순응하지 않은 경우(n=8)의 12.5%, 50%, 37.5%에 비하여 유의하게 호전되었다(P=0.0457). 결론 : 생리적 포경이 무증상 세균뇨와 무균농뇨의 중요한 원인이며 비견인 포피에 대한 스테로이드 국소 치료나 포피 위생 등 간단한 치료로 무증상 세균뇨와 무균농뇨의 상당수가 호전될 수 있었다.

Parabens are most wildly used in food, cosmetics and pharmaceutic products as preservatives caused of safety and cheap. we had examined that paraben had estrogenic activity through the in vivo and in vitro experiments in last year. We demonstrated that most of parabens(ethyl, butyl, propyl, isobutyl, isopropyl) increased significantly uterus weight as well as induced proliferation of MCF-7 cell and binding of estrogen receptor as endocrine disrupter compounds. In this study, we evaluated that whether parabens have effect on male reproductive system or not. the male rats were administrated parabens by oral injection then examined separation of preputial day for $PND23\simPND52$. As the results, most parabens delayed pubertal development compare to control group. The separation of preputial day of Butyl and Propyl parabens at high concentration were PND 44 days and PND 45days compared to control group as PND 40 days. Even though, parabens as endocrine disrupter wildly spread in food, cosmetics and pharmaceutic products, we didn't have the safe guideline. In abroad, they are re-evaluating safety assessment for parabens. In conclusion, parabens delayed pubertal development in juvenile parabens are consider as endocrine disrupter chemicals.

Purpose: Urethral reconstruction following failed hypospadias repair is difficult because of a severe shortage of the skin on ventral surface of the penis. We experienced a successful reconstruction of a failed hypospadias repair using the radial forearm free flap. So we present our case. Methods: A 16 - year - old boy had a proximal shaft hypospadias and had been taken a transverse preputial island flap but it completely broke down. There was no spare skin on the shaft of the penis. So we reconstructed a neo - urethra and the ventral skin of the penis with the radial forearm free flap. Results: Postoperatively he made relatively good process. The urethral catheter was maintained for 10 days and self - voiding was started. The suprapubic catheter was removed at the postoperative 30th day after control of cystitis. The postoperative appearance of the penis is acceptable and a straight erection is achieved. Conclusion: In the scarred penis with hypospadias, the radial forearm free flap transfer is a reliable reconstructive method for the neo - urethra and the ventral skin of the penis.

생후 10일령 수컷 진도견이 무뇨증을 주 증상으로 하여 내원하였다. 신체검사를 통하여 포피 및 포피구멍이 존재하지 않아 선천적인 비뇨생식기 기형으로 진단하였다. 무뇨증을 치료하기 위하여 요도 탐색술을 실시하였다. 정중하복부의 피하에서 음경을 확인하고 음경을 외부로 노출시킨 후 피부를 봉합하였다. 환축이 성장함에 따라 음경이 주변 피부조직에 교약 및 건조되며 울혈이 발생하였다. 이에 대한 수술적인 치료로써 파하직에 터널을 만들어 인공적으로 포피와 포피구멍을 만드는 재건술을 실시하고, 이 부위로 음경을 환납하였다. 이후 합병증 없이 정상적인 배뇨를 보였다. 포피의 무형성이 있으나 음경이 정상적인 위치에 존재한다면 포피 및 포피구멍 재건술을 통하여 정상적인 배뇨를 할 수 있을 것으로 사료된다.

It is well known that many pesticides possess hormonal activity, and affect the developments of wildlife and mammals including human. Currently, pyrethroid insecticides are in worldwide use to control in and outdoor pests, providing potential far environmental exposure. Hormonal activities of these pyrethroid insecticides, however, have been little studied, and the developmental effects of them were no reported. Therefore, we firstly examined the potential estrogenic activities of some pyrethroid insecticides (permethrin, cypermethrin, tetramethrin, deltamethrin, sumithrin, fenvalerate and bioallethrin) by immature rat uterotrophic assay, luciferase reporter gene assay and Calbindin-D$\sub$9k/ (CaBP-9k) gene expression assay. Uterine wet weights were increased by permethrin and the permethrin-induced weights were inhibited by ICI 182780 in the uterolrophic assay. On the other hand tetramethrin significantly reduced uterine and vaginal wet weights, and also inhibited the E2-induced weight increases at all doses tested. Cypermethrin and sumithrin had a tendency to increase uterine weights, although not statistically significant. Permethrin and cypermethrin dose-dependently increased the luciferase activity in reporter gene assay. Northern blot analysis showed that permethrin induced CaBP-9k mRNA expression whereas tetramethrin inhibted. Subsequent studies were conducted to investigate the possible developmental effects of four pyrethroid insecricides (permethrin, cypermethrin, sumithrin and teramethrin). Either diethlbestrol (DES) or 17${\beta}$ -estradiol (E2) was used as a reference control in this study. Pyrethroid insecticides were administered to Sprague Dawley rats via subcutaneous injection at 6 to 18 days of gestation or 1 to 5 days after birth. In utero treatment of permethrin (10mg/kg/day) in female rat resulted in significant increases in uterine and ovarian weights while significant decreases in serum E2 concentration, uterine and ovarian ER${\alpha}$ mRNA levels. Sumithrin and permethrin led to acceleration in vaginal opening of female rat, while delay in preputial separation of male after neonatal treatment. Anogenital distances of PND 18 were significantly reduced in sumthrin-treated, and permerhrin-treated male rats after neonatal treatment. All the pyrethroid insecticides tested caused significant increases in uterine weights on PND 18, while significant reductions in the first diestrus phase when neonataly treated. In addition, exposure to pyrethroids in neonatal period led to significant reduction in relative brain weight in female rat on PND 18, but its weight was recovered in diestrus phase. In summary, Our experimental data demonstrate the possibilities of developmental effects of pyrethroid insecticides via estrogenic or antiestrogenic activity.
