OBJECTIVES: To learn which inhibition of nitric oxide synthase with L-nitro arginine methylester(L-NAME) induces a preeclampsia-like syndrome in pregnant rabbits and high dose of L-arginine reverse the adverse changes induced by nitric oxide synthesis inhibition in pregnant rabbits. MTERIAL AND METHOD: Twenty Newzealand rabbits with 22-days of gestation were injected subcutaneously with 400mg of L-NAME for 7days and 100mg/kg L-arginine was also given intravenously 10 of 20 L-NAME injected pregnant rabbits. They are compared with the control group in which same volume of saline was subcutaneously injected to 5 rabbits with same condition. They were anesthesized by ketamine 50 mg/kg and roupum 2 mg/kg intramuscularly. Cutdown of femoral artery was performed and 22 gauge angioneedle was inserted. On manometer,three way catheter was connected, zeroed with saline, and blood pressure was read. Blood samples were taken from the vein of ear and checked for count of blood cells and bood chemistry (BUN/Cr, GOT/GPT, LDH, Uric acid). Urine protein was measured with nelaton catheterized urine. We injected drugs for 7 days begining on 22 days after mating and performed cesarian section to deliver fetus. To observe their effects on organs, lung, liver, placenta and kidney were taken and fixed with formalin. The sliced kidney tissue in thickness of 1 mm, was fixed with glutaraldehyde for electron microscopy and stored at 4degree C. Special staining was done for closed observation of pattern changes. For statistical analysis, mean+/-SEM was used. The control and experimental groups were compared by unpaired t-test and the differences were significant if probability level is less than 0.05(<0.05). RESULT: Mean blood pressure(MAP) in the experimental group I was significantly high compared to the control group(P<0.05). There was no significant differences in MAP between experimental group II and control group. Urine Protein, BUN, Cr, GOT/GPT, LDH, platelet count in the experimental group I was significantly high(p<0.05) compared to the control group. There was no significant difference between experimental group II and control group. In light microscopic examination, lung, liver, kidney, placenta showed specific finding in experimental group I. Misconstructive of glomerulus in the experimental kidney was well preserved under EM examination. Interstitium of kidney was widened by increase of mesangial matrix. Mild effacement of foot process and cytoplasm of proximal tubule containing electron dense myelin figure like structure were observed. CONCLUSION: Long term injection of L-arginine analogue produced preeclampsia like syndrome and pathologic changes of organ system in pregnant rabbits. Concurrent high dose of L-arginine reversed such chages.

Leiomyomas of the vagina are rare benign solid tumors. A leiomyoma arises frommuscle in the round ligament and appears as a firm movable tumor deep in the substanceof the labium majus, but minority of these tumors occur in vaginal wall. A case of a 39year old woman with leiomyoma of the vaginal orifice was reported with a brief review ofliterature.

Hemangiomas of the bladder are a rare but recognized cause of gross hematuria. In many cases, the tumor shows the characteristics of an iceberg, with considerable extravesical extension making endoscopic management less suitable. In spite of its benign nature, bladder hemangioma may grow continuously, and spontaneous regression is rare. They need to be adequately treated to avoid recurrent fatal hematuria and appropriately followed up to detect recurrency or persistency. We report a case of cavernous hemangioma of the bladder in 26-year-old woman, who presented recurrent gross hematuria and was treated with partial cystectomy.

BACKGROUND: The optimum surgical treatment for rectal prolapse is controversial, and many different operations have been described. The aim of this study is to evaluate the results of a perineal procedure for the treatment of rectal prolapse. METHODS: Between February 1990 and March 1997, 16 consecutive patients underwent perineal rectosigmoidectomy for a complete rectal prolapse. One patient was lost to follow up. The remaining 15 patients were followed up for an average of 58.4 (9~94) months, and clinical and functional outcomes were evaluated. RESULTS: There were 8 males and 7 females, and ages ranged from 18 to 65 years. The mean prolapse duration was 10.7 (0.25~30) years. There were no postoperative deaths. Two patients developed postoperative complications (one wound infection and the other wound hematoma). Five patients had fecal incontinence prior to surgery. Three of the five patients had improved fecal incontinence after the procedure. There were three recurrences (recurrence rate of 20%): one of them underwent a Delorme operation at our institution and others had no treatment. CONCLUSION: A perineal rectosigmoidectomy is a safe and effective operation for the primary treatment of rectal prolapse and has low mortality and morbidity.

PURPOSE: To determine the clinical and pathological risk factors for subsequent bladder tumor in patients with primary upper tract urothelial tumor, we retrospectively analyzed patients with upper tract urothelial tumor, focusing on the clinicopathological features of subsequent bladder tumor. MATERIALS AND METHODS: Risk factors, disease free rate and survival were assessed with clinicopathological features in 56 patients with upper tract urothelial tumor operated between 1989 and 1998. We excluded the patients with lymph node metastasis or distant metastasis, those with a short period of follow-up, and those having a previous history of bladder tumor. Risk factors such as sex, age, location of tumor, size of tumor, number of tumor, synchronous bladder tumor, preoperative urine cytology, stage, grade, operation method, and adjuvant chemotherapy were investigated. RESULTS: Initial subsequent bladder tumor was found in 36 patients (53.6%) during follow-up period of 44 months (range 13 to 111). Among several clinicopathological factors examined, only urine cytology was significantly correlated with the incidence of subsequent bladder tumor (p<0.05). Sex, age, location of tumor, size of tumor, number of tumor, synchronous bladder tumor, stage, grade, operation method, or adjuvant chemotherapy did not affect subsequent bladder tumor recurrence. There was no significant difference in survival rates between the patients with and without subsequent bladder tumor. CONCLUSIONS: Of the clinical and pathological risk factors for subsequent bladder tumor in patients with primary upper tract urothelial tumor, only preoperative urine cytology was significantly correlated with subsequent bladder tumor.

Hyperemesis gravidarum is a complication defined as nausea and vomiting during early pregnancy. Wernickes encephalopathy is an illness of acute onset characterized by mental disturbance, paralysis of eye movements, and ataxia of gait cause by thiamine deficiency. We recently experienced a case of Wernickes encephalopalhy due to hyperemesis gravidarum, which is treated by administration of thiamine even though outcome of serious healthy problem to both mother and fetus, and reported it with a brief review of the literature.

OBJECTIVE: The incidence of idiopathic thrombocytopenic purpura (ITP) is greatest in female during their childbearing years, so the concurrence of pregnancy and ITP is not unusual. Numerous studies have examined the outcomes of newborns, whereas fewer studies have been conducted with regard to the morbidity of obstetric patients with ITP. This study was aimed to find the outcome of pregnancy combined with ITP and the influence of the pregnancy on the severity of this disease. METHODS: From January 1996 to December 2005, a total of 62 pregnant women with ITP and their 73 deliveries were recruited for the study. Among them, 38 were diagnosed with ITP during pregnancy and the other 24 had pre-existing ITP before pregnancy. RESULTS: The severity of thrombocytopenia was exacerbated during pregnancy, but recovered to a level of non-pregnant period after delivery in most cases. The outcome of pregnancy of all the patients was uneventful except each one case of fetal demise at 35 gestational weeks and preterm delivery at 30 gestational weeks. One patient suffered from multiple subdural hemorrhage during pregnancy, which was spontaneouly recovered. Twenty newborns (27.8%) had transient congenital thrombocytopenia and 18 of them required treatment for hemostatic impairment. CONCLUSION: For women with ITP, Pregnancy can affect the severity of ITP, but life-threatening complication was almost lacking. Although, in not a few cases, there may need to treat both mothers and infants to raise their platelet counts, most mothers with ITP can proceed with their pregnancies and delivery healthy infant without complication.

OBJECTIVE: To investigate the relationship between umbilical plasma erythropoietin(epo) concentrations and umbilical cord pH in high risk pregnancies. METHODS: We measured epo concentrations and gas in 103 cases of cord blood obtained from 88 cesarean section (15 of twin) composed of 39 cases of normal control (12 of normal twins), 45 cases of high risk pregnancies and 4 cases of unclassified group using an RIA kit from december,1998 to December, 1999. Statistical analysis was performed using the student's t test and regression analysis. P values less than 0.05 were considered statistically significant. RESULTS: Umbilcal plasma epo concentrations revealed significant inverse correlation (P<0.05) with umbilical acidosis and cord blood epo levels, and it were significantly higher in GDM and IUGR than normal pregnancies (control: 1.60 1.15, n=39 versus GDM: 7.78 7.18, n=11 versus IUGR: 64.77 90.57 n=10, p<0.05), but 11 cases of fetal distress and 13 cases of preeclampsia did not differ significantly from umbilical plasma epo of normal control. CONCLUSIONS: Elevated epo concentrations in cord blood indicate fetal hypoxia and It is significantly increased in IUGR and GDM, these findings show that cord blood epo may serve as a clinically useful marker for chronic fetal hypoxia.
