Adenomyotic cyst is very rare disease, their sizes are mostly lesser 5mm. The intrauterine adenomyotic cyst may arise from progressive expansion of cyst due to progressive menstrual bleeding. Authors experienced a case of large adenomyotic cyst within myometrium occuring in a l9-year-old woman, and who was accompanied with endometriosis. The cyst was about 3 x 3em sized, and had chocolate colored thick viscous contents, We experienced one case of adenomyotic cyst which was thought to be degenerated uterine myoma, so we report the case with a brief review of the concerned literatures.

We have studied the clinical correlations between duration of epilepsy and anticonvulsant treatment response in temporal lobe epilepsy. We evaluated correlations between the duration of epilepsy before control and frequencies after six and twelve months of antiepileptic drug treatment, respectively. And we analyzed differences of epilepsy duration between no recurrence group, reduced seizure frequencies below 25% of before control frequencies and reduced seizure frequencies above 25% of before control frequecies groups respectively. We concluded that there are no positive correlations between the duration of epilepsy and seizure frequencies after antiepileptic drug treatment (Spearman correlation coefficients 0.2801 p=0.354 at six months antiepileptic drug treatment, 0.2797 p=0.355 at twelve months). We also concluded that there are no differencies of epilepsy duration between no recurrence group, group with reduced seizure frequencies below 25% of before control frequencies and group with reduced seizure frequencies above 25% of before control frequecies after six months of antlepileptic drug treatment(p=0.6511)and after twelve months of antiepileptic drug treatment (p=0.9469).

There are various etilogic factors concerned in the formation of pulmonary edema but it is rare that pulmonary edema is elicited as a consequence of direct current shock. The cause of this complication is unknown. The mechanism of pulmonary edema is suspected that acute alteration or disparities in atrial or ventricular mechanical function of the heart consequent to the application of electrical discharge precipitate pulmonary congestion. A case of acute pulmonary edema following the use of direct current shock during anesthesia for mitral commissurotomy was experienced. The patient was treated with oxygen, diuretics, steroid, continuous positive pressure ventilation and partial cardiopulmonary bypass. The patient recovered without further event.

BACKGROUND AND OBJECTIVES: Surfactant protein A (SP-A) which plays a role in the innate host defense of lung is also expressed in Eustachian tube. However the genes underlying the susceptibility to otitis media with effusion (OME) are known insufficiently. The current study attempts to evaluate the difference in the allele distribution of SP-A1 and SP-A2 between normal subjects and subjects with otitis media with effusion. SUBJECTS AND METHOD: PCR-cRFLP-based methodology was used to detect SP-A genotypes in the 38 children with OME, and in the 55 normal newborns for control. RESULTS: The frequencies of specific genotypes such as 6A(2), 1A(2) were increased in OME group, but the frequency of 6A3 was increased in control group. CONCLUSION: It is presumed that SP-A alleles may be inductive (6A(2), 1A(2)) or protective (6A(3)) factors for OME. Specific genoytypes of SP-A may be an important determinant for the predisposition to OME.

BACKGROUND/AIMS: Local drug delivery to the bile duct may be effective to prevent proliferative cholangitis (PC) through capability of high dose administeration with minimal systemic side effects. Paclitaxel is an anticancer drug whose side effect on the stabilization of microtubule leads to cell death. The aims of this study were to establish the proliferative cholangitis model in rat, mimicking biliary stricture in human, and to test whether paclitaxel-coated nylon thread prevents biliary stricture in a PC model of rat. METHODS: PC was induced by introducing a fine nylon thread into the bile duct in a rat from 1 week to 4 week. To evaluate the effects of paclitaxel as a locally-delivered anti-proliferative drug, dog gallbladder epithelial cells were exposed to sequential concentrations of paclitaxel (0.1microM, 1microM, 10microM, and 100microM) for 20 min. in vitro, and inhibition of proliferation was measured by (3)H-thymidine uptake assay. Paclitaxel- coated 5-0 nylon threads (1.8+/-0.5 ug/3 cm thread, measured by HPLC) were made by immersion of ethanolic paclitaxel (50 mg/ml) and evaporation of the solvent. Nylon threads were inserted into the bile duct of male Sprague-Dawley rats weighing 200~50 g. Paclitaxel (n=15) and control (n=15) groups were divided with or without paclitaxel-coating procedure. The paclitaxel effects were assessed by histomorphological examination one week after thread implantation. RESULTS: The decrease of (3)H-thymidine uptake was observed at 100microM of paclitaxel exposured for 20 minutes in the presence of epidermal growth factor (50 nM/ml) than control. PC model characterized by epithelial-glandular proliferation and fibrous thickening of the bile duct wall through 1~ week. This model was established at 1 week. The effect of paclitaxel-coated nylon thread into the bile duct were evaluated after 1 week. In paclitaxel treated the luminal area, luminal length and the ratio of lumen to bile duct cross sectional area increased by 276% (p=0.044), 87% (p=0.012) and by 330% (p=0.000), respectively, versus control. The total wall area, epithelial-glandular area, and stromal area were similar between paclitaxel treated group and control (p>0.05). The bile duct wall thickness of paclitaxel group decreased by 33% (p=0.011, 273 (90)microM vs 410 (95)microM, paclitaxel vs control). CONCLUSION: Paclitaxel-coated nylon thread into bile duct was effective for the suppression of luminal stenosis, and may offer a therapeutic option for biliary stricture and biliary stricture associated disease.

PURPOSE: Cyclooxygenase-2 (COX-2) expression is up-regulated in several types of human cancers and it has been suggested that COX-2 is closely inked to carcinogenesis. The objectives of this study were to investigate COX-2 expression in periampullary cancer and to evaluate the association of the clinicopathological factors with its expression. METHODS: Thirty specimens which were resected from patients with periampullary cancers (13 pancreatic adenocarcinomas, 8 common bile duct cancers, 9 ampulla of vater cancers) were investigated by immunohistochemical staining using Anti COX-2 monoclonal Ab. The 30 specimens were divided into stain-positive and stain-negative groups. The correlation between COX-2 expression and the various clinicopathological factors including the tumor size, nodal metastasis, differentiation, perineural and vascular invasion, were studied. RESULTS: COX-2 was expressed in 69% of pancreatic adenocarcinomas, 100% of common bile duct cancers and 78% of ampulla of vater cancers. However there was no significant correlation between COX-2 expression and the clinicopathological factors. CONCLUSION: COX-2 is highly expressed in periampullary cancer. Even though there was no correlation with the clinicopathological factors, the utility of the COX-2 inhibitors in preventing or treating periampullary cancer remains undetermined but warronts further investigation.

OBJECTIVE: There have been recent reports that mesenchymal stromal cells that are harvested from adipose tissue are able to differentiate into neurons. In the present study, we administered adipose tissue derived stem cells in rats with cerebral infarction in order to determine whether those stem cells could enhance the recovery of motor function. METHODS: Cerebral infarction was induced by intraluminal occlusion of middle cerebral artery in rats. The adipose tissue-derived mesenchymal stem cells were harvested from inguinal fat pad and proliferated for 2 weeks in DMEM media. Approximately 1 x 10(6) cells were injected intravenously or into subdural space of the peri-lesional area. The rotor rod test was performed at preoperative state(before MCA occlusion), and 1, 2, 3, 4, 6, 8 and 10 weeks after the cell therapy. RESULTS: The motor functions that were assessed by rotor rod test at 1 week of the cell therapy were nearly zero among the experimental groups. However, there was apparent motor function recovery after 2 weeks and 4 weeks of cell injection in intravenously treated rats and peri-lesionaly treated rats, respectively, while there was no significant improvement till 8 weeks in vehicle treated rats. CONCLUSION: These results demonstrate that the adipose derived stem cell treatment improves motor function recovery in rats with cerebral infarction.
