$17{\alpha}$-hydroxylase and 17,20-lyase are enzymes encoded by the CYP17A1 gene and are required for the synthesis of sex steroids and cortisol. In $17{\alpha}$-hydroxylase deficiency, there are low blood levels of estrogens, androgens, and cortisol, and resultant compensatory increases in adrenocorticotrophic hormone that stimulate the production of 11-deoxycorticosterone and corticosterone. In turn, the excessive levels of mineralocorticoids lead to volume expansion and hypertension. Females with $17{\alpha}$-hydroxylase deficiency are characterized by primary amenorrhea and delayed puberty, with accompanying hypertension. Affected males usually have female external genitalia, a blind vagina, and intra-abdominal testes. The treatment of this disorder is centered on glucocorticoid and sex steroid replacement. In patients with $17{\alpha}$-hydroxylase deficiency who are being raised as females, estrogen should be supplemented, while genetically female patients with a uterus should also receive progesterone supplementation. Here, we report a case of a 21-year-old female with $17{\alpha}$-hydroxylase deficiency who had received inadequate treatment for a prolonged period of time. We also include a brief review of the recent literature on this disorder.

Continuous ambulatory peritoneal dialysis (CAPD) is a well established method of treating end stage renal failure, and is commonly used as an alternative to hemodialysis. Several complications have been observed. These include catheter malfunction, abdominal and inguinal hernia, and peritonitis. A relatively frequent complication is swelling of external genitalia, due to bowel fluid passing through a patent processus vaginalis. Special diagnostic procedures are necessary to determine the nature of the abnormality and to guide the surgical correction. We reported two cases of patent processus vaginalis in patient on CAPD proved by radionuclide peritoneal scintiscan using Tc-99 m-tin colloid.

Urethral reconstruction is a problematic issue, thus its management can be challenging. Different methods using various materials were introduced for urethral reconstruction. The authors have made some changes in the groin flap surgery, affording more successful urethral reconstruction for defects of long urethra and penile soft tissue. A 45-year-old male requested both functional and cosmetic reconstruction of his defected penis, caused by an iatrogenic urethral injury and chronic infection following removal of paraffin self-injected on the penile shaft. The defect affected the full length of the penile urethra, corpus spongiosum, and prepuce. A groin flap was designed, measuring $28{\times}10cm$. The most distal flap was utilized for the construction of the luminal surface of the neourethra; relaxed length measuring 8 cm, and the lumen wide enough. Competent external meatus and neourethra was confirmed by retrograde cystogram and the patient voided with sufficient urine caliber up to 2 years follow-up. This operative technique has advantages. Donor sites have non-hair bearing skin for the neourethra and minimal or almost notrecognizable donor site morbidity. After surgery, the patient was relieved from voiding difficulties combined with psychological stress. The author would like to introduce a unique approach for the urethral and ventral phalloplasty using the groin flap.

This study was perfomed to investigate the differentiation of rabbit blastocysts microinjected with testosterone solution. A total of 140 mixed breed does was superovulated, synchronized and hand mated. The eggs were flushed from uterine horns between 65 and 89 hrs after mating. Testosterone was dissolved in 95% ethanol and diluted with PBS at the ratio of 1: 99. Final concentration of testosterone was adjusted to 1 pg /ml. 6~8 bias-tocysts were microinjected with 1~10 p Q of the diluted testosterone solution, and tranfer-red into the uterine horns of the synchronized recipients. When 140 donor does were treat-ed with a single does of 200 IU PMSG in combination with 100 IU RCG 48 hrs apart, 134 of them(97%) showed standing estrus. Ovarian responses of 117 does were examined following mating and the rate of ovulation was 11.23 i 1.20. Ova were recovered from donors between 65 and 89 hrs after mating. Recovery rates of ova were 37.5% and 42.2% of recovered ova were blastocysts. A total of 106 blastsocysts were microinjected with testosterone solution and transferred into the uterine horns of 15 synchronized recipient does. One of the recipients was pregnant and delivered 7 baby rabbits. The external genitalia of the young rabbits appered to be the same appearance as the buck entierly.

A chromosomal study was performed in a total of 162 urological patients during past 2$2{\frac{1}{2}}$ years (Feb. 1984 - Aug. 1986). Of these 78(48%) patients had abnormal chromosome complements. Among all patients with chromosome abnormalities, 88% (69/78) had aberrations of chromosome number, 8% (6/78) had aberrations of chromosome structure and 4% (3/78) had aberrations of both. 90% (65/72) of numerical abnormality was Klinefelter's syndrome and the structural abnormality rate (5.6%, 9/162) was less than that (6.99%) of general population. The chromosomal study was mandatory for the detection of intersex in small testes or hypospadias with cryptorchism or clitoromegaly or bilateral cryptorchism. But unilateral cryptochism or hypospadias with normal scrotal testes was not thought to be indication of the chromosomal study if the external genitalia are otherwise quite normal.

Two species, Daulia afralis Walker and Herpetogramma cynaralis Walker, belonging to the family Crambidae, Lepdidoptera, are reported for the first time from Korea, based on the materials collected from Jeju Islands located in the southern part of the Korean peninsula. Both male and female genitalia were dissected and examined. Also, the photos of the external morphology, including the wing patterns, and genitalic characteristics of the two species are taken and redescribed briefly, including distributional ranges and available information. Taxonomic information and synonymies for the species were given and discussed.

After studing of viewpoint of surgical disease in seven medical books related with Ju Dan Gye(朱丹溪) among four eminent physicians in the Jin and Yuan dynasties(金元四大家) I get conclsion as following. 1. Studied surgical diseases are total 40 kinds. 2. In 40 kinds surgical diseaes, case of having theory are 20 kinds, cases of having no theory and having only treatement by medicine are 20 kinds. 3. In therapy, cases that mainly use a method to eliminate pathogenic factors are 27 kinds; Acute mastitis(乳癰), Deep-seated mammary abscess(내巖), Acute appendicitis(陽癰), Bone cellulitis(附骨疽), Carbuncle of the lower abdomen near external genitalia(便毒), Leprosy(癩風), Macule(斑), Rash(疹), Urticaria(은疹), Scrofula(나역), Stagnant plegm(結核), Goiter andtumer(영유), Erysipelas(丹), Furuncle(정瘡), Scabies(疥瘡), Chancre(下疳瘡), Syphilitic skin disease(樣梅瘡), Incised wound (金瘡), Dermatopathy of lower limb and heel(脚足部瘡), Pemphigus(天疱瘡), Itching eruption due to blood-heat or wind heat(血風瘡), Dermatopathy of head(頭面瘡), Scald and burn(湯火瘡), Tetanus(破傷風) , Ecthyma(염瘡), Fistula(久漏瘡), Tinea(癬瘡), Cases that mainly use external therapy are 5 kinds; Rhagades of hand and foot(手足군裂), Vulvar ulceration(婦人陰瘡), Chilblain(凍瘡), Rabies(풍狗咬), Tinea capitis(白禿瘡), Cases that mainly use a reinforcing method are 4 kinds; Internal deep-rooted carbuncle(內疽), Pruritus and dryness of skin(皮膚乾燥), Anul fistula(漏瘡), Macule Caused by disorder of internal organ(內傷發斑), Cases that mainly use eliminating first and then reinforcing are 2 kinds; Pyogenic infection and ulcerous disease of slin( 疽瘡상癰疽瘡瘍), Lung abscess(肺癰), Case that mainly uses reinforcement and elimination in combination is only Haemorroid(痔瘡). Case divided into two groups that are reinforcing method and a method to eliminate pathogenic factor is only Trauma(打撲). Case that have no treatment by medicine is only Abscess of the scrotum(囊癰). 4. In 40 kinds surgical diseases, we can know that except a few important surgical diseases, Ju Dan Gye haven't distinguished viewpoint in many surgical diseases, because there are many cases that have no theory and have only simple treatment of medicine, and that mainly use a method to eliminate pathogenic factors and external therapy. 5. Representative theory of Ju Dan Gye, nourishing Yin and extinguishing fire(滋陰降火), has little effect on therapy of surgical disease. We need to try statistical division of internal and external remedy in the future, and by studing of surgical disase in medical books related with four eminent physicians in the Jin and Yuan dynasties, I think we can see their viewpoint of surgical disease.

In mammals, puberty is a process of acquiring reproductive competence, triggering by activation of hypothalamic kisspeptin (KiSS)-gonadotropin releasing hormone (GnRH) neuronal circuit. During peripubertal period, not only the external genitalia but the internal reproductive organs have to be matured in response to the hormonal signals from hypothalamic-pituitary-gonadal (H-P-G) axis. In the present study, we evaluated the maturation of male rat accessory sex organs during the peripubertal period using tissue weight measurement, histological analysis and RT-PCR assay. Male rats were sacrificed at 25, 30, 35, 40, 45, 50, and 70 postnatal days (PND). The rat accessory sex organs exhibited differential growth patterns compared to those of non-reproductive organs. The growth rate of the accessory sex organs were much higher than the those of non-reproductive organs. Also, the growth spurts occurred differentially even among the accessory sex organs; the order of prepubertal organ growth spurts is testis = epididymis > seminal vesicle = prostate. Histological study revealed that the presence of sperms in seminiferous tubules and epididymal ducts at day 50, indicating the puberty onset. The number of duct and the volume of duct in epididymis and prostate were inversely correlated during the experimental period. Our RT-PCR revealed that the levels of hypothalamic GnRH transcript were increased significantly on PND 40, suggesting the activation of hypothalamic GnRH pulse-generator before puberty onset. Studies on the peripubertal male accessory sex organs will provide useful references on the growth regulation mechanism which is differentially regulated during the period in androgen-sensitive organs. The detailed references will render easier development of endocrine disruption assay.

Purpose: By virtue of good nourishment, obese boys are increasing in Korea, which may result in prevalence of cryptopenis. As milieu of economy, culture, and society changes, increased attention to the external genitalia in children should encourage surgeon to do assertive treatment for cryptopenis. But various operative methods have been devised yet to need sophistication and revision. The author performed suprapubic lipectomy and operation according to the modification of the Johnston's principle. Methods: The patient was 5 years old, 32 kg, and 122 cm. He had no pain or tenderness. The operation was done under general anesthesia. It was done with excision of suprapubic fat, cutting of retracted dartos fascia instead of removing the fascia around penile base, and anchoring of dermis and the cutting margin of the fascia to the underlying fascia such as Buck's fascia, tunica albuginea and rectus fascia at penile base. And then circumcision was performed. Results: Postoperative complication was not observed. The clinical result of the operation was satisfactory to both surgeon and parents of the patient. Conclusion: Suprapubic lipectomy and anchoring of dermis and retracted cutting dartos fascia margin to the underlying fascia in all directions at the penile base through a single suprapubic incision provide this patient with complacency.
