Authors experienced an anesthesia for aortorenal shunt operation for renovascular hypertension caused by atherosclerosis in a 38-year-old male. Tracheal topical anesthesia with 4% lidocaine was performed prior to induction of anesthesia with intravenous thiopental sodium and nitrous oxide-oxygen by mask. Semiclosed circle system with nitrous oxide-oxygen-halothane was used in the maintenance of anesthesia. Blood pressure and pulse rate were increased during manipulation of perirenal tissues in spite of administration of high concentration of halothane with nitrous oxide-oxygen and controlled respiration under positive pressure.

OBJECTIVE: To elucidate the correlation of vascular endothelial growth factor (VEGF) concentrations in follicular fluid (FF) with the ovarian response as well as the age in women undergoing controlled ovarian hyperstimulation (COH). METHODS: This study was performed in 72cycles who underwent COH for in vitro fertilization at infertility clinic of Changwon Hanmaeum Hospital and Pusan National University Hospital from Aug., 2003 to Dec., 2003. Each FF was collected at the oocyte retrieval according to the follicular size and VEGF concentrations in FF were assessed. We analyzed the correlation of VEGF concentrations in FF with ovarian response as well as the age in women undergoing COH. RESULTS: In 72cycles, the clinical pregnancy rate was 37.5% (27cycles). There were no significant differences in patient's age, ampules of gonadotropin used, estradiol (E2) level on the day of hCG administration, the number of oocyte retrieved, and fertilization rate between pregnant and nonpregnant groups. However, positive correlation was found between the follicular size and VEGF concentrations in FF in pregnant and nonpregnant groups. No significant correlation was found between age and VEGF concentrations in FF. There were no significant differences in the VEGF concentrations in FF between pregnant and nonpregnant women by age. CONCLUSION: These results suggest that VEGF concentrations in FF cannot be the marker for the prediction of ovarian response, and have no correlation with all parameters of COH including patients' age with exception for the follicular size.

BACKGROUND: The dipstick methodology is the most fundamental urinalysis but interfered by many factors. We evaluated the effect of semen contamination on the urine dipsticks. METHODS: Thirty-two specimens for semen analysis were enrolled. After semen was directly applied on urine dipsticks, residual samples were diluted in pooled normal urine. Urine dipsticks were performed at each dilution titer. Seminal plasma separated by centrifugation of semen were also tested in the same manner. RESULTS: All semen showed positive results for blood, protein and leukocytes. The intensities of reaction for blood and leukocytes were correlated with sperm concentration. The negative conversion of blood and protein occurred at 1:100, and that of leukocytes occurred at 1:50. Seminal plasma showed nearly the same findings. CONCLUSIONS: Semen contamination of urine may cause false positive reaction especially for blood and protein on the urine dipsticks. It should therefore be considered when assessing unexplained, transient hematuria or proteinuria.

The authors have experienced two cases of general anesthesia for operation of congenital tracheo-esophageal fistula and the results were obtained as follows. 1. The anesthetic agent should be selected as considering of lesser irritating to respiratory system and smaller amount of tracheobronchial secretion. 2. The infant circle absorber system has been preferred to the Ayres T-piece apparatus, because maintaining normal body temperature and removal of carbon dioxide easily. 3. Removal of secretion from trreheobronchial tree, intermittent positive pressure breathing, maintaining normal body temperature and humidity were thought to be necessary for the prevention and treatment of postogerative pneumonia or atelectasis.

PURPOSE: To apply a distributed circuit theory, to develop a head-size transverse electromagnetic(TEM) resonator coil for a home-built 3T whole-body MRI system and to report an efficiency of the coil. MATERIALS AND METHODS: The dimension of TEM resonator with 16 cavity element, the diameter of copper rod was 0.63cm and its length was 13.75cm. As raw materials, the purity of copper rod was 98% and the dielectric constant of teflon was 2.08. RESULTS: The TEM head-size resonator with 16cavity elements exhibiting 9-mode resonances was robust to the surrounding influences owing to the self-shielding structure. The isolation of quadrature with a human brain was 364 and the ratio of Q(unloaded/Q(loaded) was 2.9. CONCLUSION: It was successfully demonstrated that the TEM head-size resonator with high Q factor can provide high quality MR images at 3T MRI system. Also, the TEM resonator coil has an advantage for a fine tune with length adjustment of each cavity elements. Thus, it is expected that the TEM resonator at 3T, even higher field could be used in the clinical and research studies in near future.

BACKGROUND: The function of the p53 protein is known to regulate cell proliferation by inhibiting cells entering S phase, so DNA damaged cell proliferation is inhibited by apoptosis. p21 is a cyclin dependent kinase inhibitor induced by wild type p53, not mutant p53. Thus p21 is thought to mediate the signal of p53 induced by DNA damaged agents to arrest the cell cycle in G1 phase. p53 and p21 are expressed in many malignant tumors, and its role in oncogenesis, tumor progression and prognosis are important. OBJECTIVE: The purpose of this study was to analyze immunohistochemical expression of mutant p53 and p21 protein in melanocytic lesions. METHOD: 11 cases of intradermal nevus, 7 cases of junctional nevus and 6 cases of malignant melanoma were immunohistochemically stained with p53 and p21 monoclonal antibodies. RESULTS: 1. In intradermal nevus, the p53 was negative in 100% and the p21 was negative in 98%. These findings suggest that the composing cells of intradermal nevus is completely mature cell. 2. The positive rates of p53 and p21 in junctional nevus were 43% and 43%, respectively. The positive rates of p53 and p21 in malignant melanoma were 82% and 67%, respectively. CONCLUSION: If the expression of p21 is induced by p53 independent pathway, the cell cycle can be arrested in G1 phase, so the tumor cell proliferation is inhibited. But if the expressed p21 is mutated as p53, it means that the natural function of p21 disappears. More research is necessary about the nature of p21 which is expressed with mutant p53.

PURPOSE: To evaluate the radiological findings of abdominal malignant fibrous histiocytomas. MATERIALS AND METHODS: We retrospectively reviewed the radiological findings of 13 masses in seven patients including two patients with multiple masses. The masses were located at the mesentery and omentum in three patients and at theretroperitoneum in four. Gastrointestinal examination using barium was performed in four patients, ultrasonographyin five and computed tomography in all. RESULTS: The average diameter of masses was 7.8cm(range : 1-20cm); plain abdominal films revealed soft tissue masses in all patients. Three of four barium studies demonstrated only displacement of bowel loops and the other showed findings of submucosal tumor. Eight of 11 masses were detected on ultrasonography and all were round or lobulated and had well defined margins. Four of these masses were greater than 8cm in diameter and showed homogeneous echogenicity with central hypo or anechoic area ; the remaining wereless than 8cm and showed relatively homogeneous echogenicity. On computed tomography, all 13 masses were seen as highly enhanced and well circumscribed. Seven were greater than 5cm in diameter and had internal low-densityareas. Peritumoral vessel-like structures were seen in eight masses and on plain abdominal radiograph and computed tomogram, calcification was seen in one patient. In no patient was combined retroperitoneal or intraperitoneal lymphadenopathy noted. CONCLUSION: Abdominal malignant fibrous histiocytomas are well-circumscribed, round orlobulated bulky masses with frequent necrosis and occasional calcification. Characteristically, there is nocombined lymphadenopathy and multiple masses are a rare manifestation. These findings may be helpful in the diagnosis of malignant fibrous histiocytoma.

Emphysematous pyelonephritis is an uncommon and potentially life-threatening infectious disease. Although there is still controversy about optimal treatment of emphysematous pyelonephritis, published results indicate that the mortality rate in the patients treated with radical nephrectomy is equivalent to that in patients given more conservative treatment. Emphysematous pyelonephritis with autosomal dominant polycystic kidney disease is extremely rare and its clinical course is not revealed clearly. Hearin, we report an emphysematous pyelonephritis in a 64- year-old female patient with autosomal dominant polycystic kidney disease, successfully treated by antibiotics and percutaneous cyst drainage.
