A clinical study of 106 cases of $Henoch-Sch{\ddot{o}}nlein$ purpura was made. The author analyzed the result of Korean traditional medical therapy. It was observed more frequently in female at the sex ratio of 1:1.3. The most prevalent age group was $4{\sim}9$ years(56.6%). In seasonal incidence, the cases were frequent during spring(50%), and the main specific history was upper respiratory tract infection(48.1%). The duration of contraction was $420.9{\pm}1079.3$ days. The adults were more chronic than children (p<0.05), The clinical manifestation showed in the skin (100%), the gastrointestinal tract(62.3%), the joints(64.2%), the kidney(25.3%), genitourinary system(11.3%), headache(6.6%), and scalp edema(4.7%) respectively. The first outbreak of symptoms was showing of skin purpura in 77 cases(72.6%) the highest frequency. and the gastrointestinal tract and joints were 16(15.1%) and 12 cases(11.3%) respectively. Of all patients, 22 cases(20.8%) experienced recurrences and 47 patients(44.3%) experienced hospitalization treatment. In the patients group which were recurrence experiences, the recurrence rate was high with patients(63.2%) who usually enjoyed meats and convenience foods and in patients(84%) who treated URI with chemical drugs(p<0.05). The patients group(68.9%) that took steroids also experienced a relatively high recurrence rate. Out of the patients(68.9%) who took treatment with steroids, 46.6% experienced side effects, in orders moon face(100%), weight gain(47.1%), appetite increase(52.9%), and acne. alopecia(11.8%), etc. There was a statistically significant relationship between the period of taking the steroid and the side effects(p<0.05), As the result of the herbal medicine treatment(treatment period: $6.7{\pm}6.2$ weeks, a follow-up survey during $15{\sim}24$ months), 67 patients(91.8%) among the 73 patients(68.9%) under 18 years old recovered completely but 3 cases(4.5%) recurred. 23 patients(69.7%) among the 33 patients(31.3%) above 19 years recovered completely but 5 cases(21.7%) recurred.

Some organotin compounds such as butyltins and phenyltins are known to induce impo-sex in various marine animals and are considered to be endocrine disruptors. In this study, the effect of organotins on follicular steroidogenesis in amphibians was examined using ovarian follicles of Rana dybowskii and Rana catesbeiana. Isolated follicles were cultured for 6 or 18 h in the presence and absence of frog pituitary homogenate (FPH) or various steroid precursors, and the levels of product steroids in the culture media oassay. Among the butyltin compounds, tributyltin (TBT) strongly and dose-dependently inhibited the FPH-induced synthesis of pregnenolone ($P_5$) and progesterone ($P_4$) by the follicles. TBT also strongly suppressed the conversion of cholesterol to $P_5$ and partially suppressed the conversion of $P_5$ to $P_4$. A high concentration of dibutyltin (DBT) also inhibited steroidogenesis by the follicles while monobutyltin and tetrabutyltin had negligible effects. The toxic effect of TBT or DBT was irreversible and a short time of exposure (30 min) was enough to suppress steroidogenesis. All the phenyltin compounds significantly inhibited FPH-induced $P_5$ synthesis by the follicles. The effective dose of 50% inhibition by diphenyltin was $0.04\;{\mu}M$ and those of monophenyltin and triphenyltin were $0.24\;{\mu}M$ and $0.3\;{\mu}M$, respectively. However, none of the phenyltin compounds significantly suppressed the conversion of $P_4$ to $17{\alpha}$-hydroxyprogesterone ($17{\alpha}$-OHP) (by $17{\alpha}$-hydroxylase), $17{\alpha}$-OHP to androstenedione (AD) (by $C_{17-20}$ lyase), or AD to testosterone by the follicles. Taken together, the data show that among the steroidogenic enzymes, P450scc in the follicles is the most sensitive to organotin compounds and that an amphibian follicle culture system can be a useful screening model for endocrine disruptors.

Leiomyomas, which are the commonest pelvic tumors in women, are originated from myometrial cells. Although the exact initial pathophysiologic event of the leiomyoma is not known, recent evidences suggested that the effects of sex steroid hormones in the process of tumor growth are mediated by local production of growth factors including epidermal growth factor (EGF), insulin-like growth factor-I (IGF-I) and insulin-like growth factor-II (IGF-II). If we look at the effects of other cytokines, it was suggested that basic fibroblast growth factor (bFGF) may stimulate the proliferation of myometrial and leiomyomas cells. And it was reported that interferon-${\alpha}$ inhibit the action of bFGF. Therefore, we examined the effect of bFGF and interferon-${\alpha}$ on the proliferation of leiomyoma and myometrial cells. bFGF stimulated the myometrial and leiomyoma cells significantly at the concentration of 1ng/ml (p<0.05) and 5ng/ml (p<0.05). However, Interferon-${\alpha}$ inhibited the cell proliferation of myometrial and leiomyoma cells significantly at the concentration of 100U/ml (p<0.05) and 1000U/ml (p<0.05). And the stimulated effects of bFGF with the various concentration on the myometrial and leiomyoma cells ware inhibited by interferon-${\alpha}$ with 100U/ml. Therefore, we concluded that bFGF may stimulate the myometrial and leiomyoma cell proliferation and interferon-${\alpha}$ may inhibit the myometrial and leiomyoma cell proliferation through blocking the effect of basic fibroblast growth factor.

A neurotoxin, 6-hydroxydopamine (6-OHDA) has been widely used to create animal model for Parkinson's disease (PD). The present study was undertaken to examine whether depletion of brain dopamine (DA) stores with 6-OHDA can make alteration in the activities of the testicular steroidogenesis in adult rats. Young adult male rats (3 months old) were received a single dose of 6-OHDA (200 ${\mu}g$ in 10 ${\mu}{\ell}$/animal) by intracerebroventricular (icv) injection, and sacrificed after two weeks. The mRNA levels of steroidogenesis-related enzymes were measured by qRT-PCRs. Serum testosterone levels were measured by radioimmunoassay. Single icv infusion of 6-OHDA significantly decreased the mRNA levels of CYP11A1 (control:6-OHDA group=$1:0.68{\pm}0.14$ AU, p<0.05), CYP17 (control:6-OHDA group=$1:0.72{\pm}0.13$ AU, p<0.05). There were no changes in the mRNA levels of $3{\beta}$-HSD (control:6-OHDA group=$1:0.84{\pm}0.08$ AU) and $17{\beta}$-HSD (control: 6-OHDA group=$1:0.63{\pm}0.20$ AU), though the levels tended to be decreased in the 6-OHDA treated group. Administration of 6-OHDA decreased significantly the mRNA level of StAR when compared to the level of saline-injected control animals (control:6-OHDA group=$1:0.72{\pm}0.08$ AU, p<0.05). Treatment with single dose of 6-OHDA remarkably lowered serum testosterone levels compared to the levels of control group (control:6-OHDA group=$0.72{\pm}0.24:0.13{\pm}0.03ng/m{\ell}$, p<0.05). Taken together with our previous study, the present study demonstrated that the activities of hypothalamus-pituitary-testis hormonal axis could be negatively affected by blockade of brain DA biosynthesis, and suggested the reduced reproductive potential might be resulted in the animals. More precise information on the testicular steroidogenic activities in PD patients and PD-like animals should be required prior to the generalization of the sex steroid hormone therapy to meet the highest standards for safety and efficacy.

To clarify annual reproductive cycle of Koran dark sleeper, odontobutis platycephala, we examined the seasonal changes of gonadosomatic index(GSI), testicular development stages and sex steroid hormones in blood from December 1995 to November 1997. Testis was podlike shape from July to October, and tadpole-like shape from November because of its expanded posterior part. GSI was 0.14~0.18 from July to September and increased to $0.43{\pm}0.04$ in October and then was not changed significantly until February. GSI was reincreased to $0.52{\pm}0.09$ from March and then was kept at similer levels until May, but fell down to $0.28{\pm}0.05$ in June. As results of histological observation, testis was divided into 3 parts(anterior, boundary, posterior) in the development progress of germ cells. In July, the testis was composed of only spermatogonia without seminiferous tubules in most fishes. In the anterior part of testis, the ferquency of spermatogenesis stage seminiferous tubules appearing in August was more than 80% from September to December. decreased gradually from January to March and drastically in April, and then disappeared in June. The frequency of spermiogenesis stage seminiferous tubules appearing in December, increased gradually from January to March and drastically to 80% in April, and reached to 90% the highest levels of the year in June. Post-spawning stage seminiferous tubules did not appear throughout the year. The frequency of spermatogonia was 100% and 65% in July and August, and less than 20% in the rest period of the year. In the boundary part, the frequency of spermatogenesis stage seminiferous tubules appearing in August increased from September and reached to 82% in November, decreased from December, adn disappeared in March. The frequency of spermiogenesis stage seminiferous tubules appearing in November was less than 18% until February, and increased to 29%~57% from March to June. The frequency of post-spawning stage seminiferous tubules appeared 12%~25% only from March to June. The frequency of spermatogonia was 100% in July, decreased to 85% in August and 10% in November, and increased gradually from December to 50% in April, and decreased again from May to June. In the posterior part, seminiferous tubules with some seminiferous tubules increased drastically 80%~85% in August and September, decreased drastically from October to November and remained below 10% until February, and disappeared after March. The frequency of spermiogenesis stage seminiferous tubules appearing in August increased sharply from October and reached to 75% in November. decreased to 15% in December and no significant changes until March, and disappeared after April. The frequency of post-spawning stage seminiferous tubules appearing very early in November increased to 82% in December and 85%~95% until June. The frequency of spermatogonia was 100% in July, decreased drastically to 15% in August, disappeared from October to Mrch, but reappeared from April and kept at less than 10% until June. The blood level of testosterone (T) increrased gradually from August was $0.61{\pm}0.09 ng/m\ell$ in November, increrased drastically to $3.99{\pm}1.22 ng/m\ell$ in December and maintained at in similar level until March, and decreased to $0.25{\pm}0.14 ng/m{\ell} ~ 0.17{\pm}0.13ng/m{\ell}$ in April and May and no significant changes until July (P<0.05). The blood level of 17, 20 -dihydroxy-4-pregnen-3-one $ng/m{\ell}$in the rest of year without significant changes(P<0.05). Taken together these results, the germ cell development of testis progressed in the order of posterior, boundary, anterior part during annual reproductive cycle in Korean dark sleeper. The testicular cycle of Korean dark sleeper was as follows. The anterior part of testis : i.e. spermatogonial proliferation period (July), early maturation period (from August to November), mid maturation period (from December to March), late maturation period (from April to May) and functional maturation period (June) were elucidated. The boundary of testis, i.e. spermatogonial proliferation period (July), early maturation period (from August to October), mid maturation period (from November to February) and the coexistence period of late maturation, functional maturation and post-spawn (from March to June) were elucidated. The posterior of testis, i.e. spermatogonial proliferation period (July), mid maturation period (from August ot September), late maturation period (October), functional maturation period (November) and post-spawn period (from December to June) were elucidated. It was showed that the changes of sex steroid hormone in blood played a important roles in the annual reproductive cycle of Korean dark sleeper.

Purpose : Efforts to predict long-term outcome of focal segmental glomerulosclerosis(FSCS) have been made but have yielded conflicting results. Reports are rare especially in Pediatric patients. In this study, we reviewed the predictable prognostic factors in patients of FSGS Method : Fifty children who diagnosed as biopsy-proven FSGS at department of pediatrics at Yonsei university were studied retrospectively. Based on medical records, response to treatment and pathologic slides, we compared normal renal function group and decreased renal function group, assessed the factors affecting renal survival and progression to renal failure. Results : The mean age at onset was 8 1/12 years, sex ratio was 2.3 : 1, and the mean duration of follow-up was 7 1/12 years. The overall renal survival rate was $34\%$ at 5 years, $8\%$ at 10 years Five-year survival rate was $74\%$ in normal renal function group and $27\%$ in decreased renal function group. Between the two groups, there were no significant differences in age at onset, sex ratio, amount of proteinuria, incidence of hematuria and hypertension, mesangial hypercellularity. Decreased renal function group showed higher serum creatinine level, poor response to treatment, higher percent of glomeruli with sclerosis, moderate to severe tubulointerstitial change and vascular change(P<0.05). The prognostic factors of renal survival rate were same as above and incidence of hypertension also affected renal survival( P<0.05). The progression rate to renal failure did not show statistically significant factor. Conclusion : We reviewed the factors affecting long-term outcome of FSGS. Serum creatinine level, steroid responsiveness, and the degree of glomerulosclerosis were significant prognostic factors. (J Korean Soc Pediatr Nephrol 2001 ;5 : 125-35)

There are too many kinds of esophageal corrosive agents, such as sodium hydrochloride, acetic acid, hydrochloric acid, etc. Esophageal burn due to above chemical agents are decreasing recently, but still many patients visited to the hospital because of swallowing corrosive agents for the purpose of suicide or accidentally. Among the treatment of corrosive injury of the esophagus, prevention of esophageal stricture is the key point. Recently various methods are using as the treatment of corrosive esophagitis and prevention of esophageal stricture. 51 cases of corrosive injury of the esophagus who had been admitted and treated at the Dept. of Otolaryngology, Han Yang University Hospital during past 9 years (from May 1972 to Dec. 1980) were evaluated and report the result about age distribution, sex incidence, monthly distribution, cause of swallowing, swallowing agents, arriving time at hospital after swallowing, changes on oral and pharyngeal mucosa, laboratory findings, emergency treatment and treatment during admission, treatment follow up results and complications with review of liter ature. Following results were obtained; 1. Female patients 27 cases (52.9%) were more than male patients 24 cases (47.1%) and its ratio was 1.13 : 1. 2. Age distribution showed predilection for age of 21-30 with 20 cases(39.2%), and 11-20 with 11 cases (21.6%), 31-40 with 7 cases(13.7%), over 50 with 7 cases (13.7%) were following. 3. Monthly distribution showed predilection for March with 8 cases(15.7%), and April, July with 7 cases (13.7%), September with 6 cases(l1.8%), October 5 cases(9.8%) were following. 4. For the purpose of suicide was the most cause of swallowing with 40 cases(78.4%), and accidentally swallowing 11 cases(21.6%). 5. Acetic acid was the most swallowing agent with 24 cases (47.0%), and hydrochloric acid 11 cases (21.5%), lye 8 cases(15.7%), iodine 2 cases(3.9%) were following. 6. Arriving time at the hospital after swallowing showed predilection for within 12 hours with 42 cases (82.4%), and from 12 hours to 24 hours with 4 cases(7.8%) was next. 7. Moderate change with injection and swelling was the prevalent change on oral and pharyngeal mucosa with 20 cases(39.2%) and severe cases with ulceration 18 cases (35.3%), mild cases with injection 10 cases (19.6%) were following. 8. Leukocytosis was seen on 40 cases (78.4%), and increased Hct. was seen 31 cases (60.8%). On urine analysis, 14 cases(27.5%) showed over 1.030 S.G., and proteinuria was seen on 25 cases(49.0%), glycosuria was seen on 5 cases(9.8%) and hematuria was seen on 6 cases(11.8). 9. Gastric lavage was done on 30 cases (58.8%) as emergency treatment and on 3 cases(5.9%) tracheostomy was done for the airway keeping. 10. As methods of treatment during admission, L-tube insertion was done on 50 cases (98.0%), antibiotics was given to 49 cases (96.1%), steroid and antacid were given to 46 cases(90.2%). 11. 36 cases(70.6%) were in favorable condition after proper treatment, but 2 cases (3.9%) were expired during admission, 4 cases (7.8%) showed esophageal stricture in-spite of treatment, and 1 case(2.0%) showed pyloric stenosis. 12. Complications were observed in 8 cases (17.7%). Renal failure (4 cases), aspiration pneumonia (2 cases), upper G-I bleeding (1 cases), and diabetic coma (1 cases) were seen in order of frequency.

Blood chemical values and sex steroid hormone concentration of repeat breeder and reproductive disorder in Hanwoo, which were bred in Chunchon areas, were examine to establish the basic physiological maker. The concentrations of albumin, blood urea nitrogen(BUN), calcium(Ca), cholesterol, creatinine, glucose, phosphorous, total protein and triglycerides in repeat breeder and reproductive disorder were 3.28$\pm$0.05 and 3.27$\pm$0.04 g/㎗, 11.07$\pm$0.61 and 12.69$\pm$0.88 mg/㎗, 9.98$\pm$0.10 and 9.56$\pm$0.11mg/㎗, 105.75$\pm$3.57 and 126.78$\pm$5.66mg/㎗, 1.62$\pm$0.05 and 1.65$\pm$0.09 mg/㎗, 67.46$\pm$9.07 and 76.97$\pm$3.76mg/㎗, 6.13$\pm$0.36 and 6.11$\pm$0.26mg/㎗, 5.82$\pm$0.08 and 6.18$\pm$0.08 g/㎗ , 12.82$\pm$1.46 and 15.19$\pm$1.61mg/㎗, respectively. Among the blood chemical values, Ca, cholesterol and inorganic phosphorous levels in repeat breeder and reproductive disorder were slightly higher than those in normal cows. The progesterone levels of pregnancy(0.18~6.56 ng/$m\ell$) and non-pregnancy(0.15~5.46ng/$m\ell$) cows at estrus cycle were showed similar trends from 0 day to 18 days. Those of pregnancy cows were increased gradually from 18 days to 180 days(5.90~7.51 ng/$m\ell$), while those of non-pregnancy cows were dramatically drop at 21 days (0.18$\pm$0.03mg/㎗). The concentrations of estrogen and progesterone in repeat breeder and reproductive disorder were 57.42$\pm$5.03, 56.76$\pm$8.73 pg/$m\ell$ and 6.26$\pm$0.83, 9.41$\pm$1.85 ng/$m\ell$ . respectively. These results indicate that blood chemical values in repeat breeder and reproductive disorder were not greatly difference in normal cows except for Ca, cholesterol, BUN and inorganic phosphorous. Since the progesterone levels in repeat breeder and reproductive disorder was maintained to the luteal phase levels of normal cows, it may cause of failing of conception and next estrus cycle.

Numerous hormones are involved in the regulation of reproduction. Among them, estrogen and progesterone are the most important ovarian steroid hormones regulating female fertility. On the other hand, diverse stressors impede female receptivity and fertility. Since norepinephrine(NE) and epinephrine(E) are released from the adrenal during stress, it might play a role in stress-induced disruptions of fEmale reproductive parameters. The present study was performed to analyze the changes in adrenal catecholaminergic activities in cycling rats. The tissue content and secretion level of catecholamines were determined by high performance liquid chromatography coupled with electrochemical detector(HPLC-ECD). Adrenomedullary content of norepinephrine(NE) was increased on proestrus stage (59.47 $\pm$ 6.86 ug/gland), peaked on diestrus I stage(65.22 $\pm$ 5.99 ug/gland), and was nadir on diestrus II stage(41.63 $\pm$ 1.33 ug/gland). The highest E content was observed on proestrus stage(361.86 $\pm$ 15.58 ug/gland) while the lowest level was on diestrus II stage(285.58 $\pm$ 12.25 ug/gland). In addition to these observations, a significant reduction of the NE : E ratio was observed (1 : 4.81 on diestrus I vs 1 : 6.13～7.02 on other stages). In vitro secretion of adrenal NE and E was increased on proestrus stage, peaked on estrus stage, and decreased on diestrus II stage. Interestingly, the NE : E ratio in conditioned media was significantly increased on estrus stage (1 : 3.32 vs 1 : 2.34～2.65 on other stages. The biosynthesis of NE and E is mediated by tyrosine hydroxylase(TH) and phenylethanolamine-N-methyltransferase(PNMT) which acts conversion of tyrosine into DOPA and NE into E, respectively. These finding demonstrated that sex steroids, during setrous cycle, seem to be able to modify the adrenal catecholamines biosynthesis and secretion with stage-specific manner by modulation of the enzyme activities.
