OBJECTIVE: To evaluate the effects of recombinant FSH (rFSH) and urinary FSH (uFSH) on the gene expressions of human endometrial stromal cells in vitro. METHODS: Endometrial tissue was obtained from a pre-menopausal women undergoing hysterectomy. Primary endometrial stromal cells were isolated and in vitro cultured with FBS-free DMEM/F-12 containing 0, 10, 100, and 1,000 mIU/ml of rFSH and uFSH for 48 hours, respectively. Total RNA was extracted from the cultured cells and subjected to real time RT-PCR for the quantitative analysis of progesterone receptor (PR), estrogen receptor alpha/beta (ER-alpha/beta), cyclooxygenase 2 (Cox-2), leukemia inhibitory factor (LIF), homeobox A10-1 and -2 (HoxA10-1/-2). RESULTS: Both hormone treatments slightly increased (< 3 folds) the expressions of PR, ER-beta and HoxA10-1/-2 gene. However, ER-alpha expression was increased up to five folds by treatments of both FSH for 48 hours. The LIF expression by the 10 mIU/ml of uFSH for 12 hours was significantly higher than that of rFSH (p<0.01). After 24 hours treatment of two kinds of hormones, the expression patterns of LIF were similar. The 100 and 1,000 mIU/ml of rFSH induced significantly higher amount of Cox-2 expression than those of uFSH, respectively (p<0.05). CONCLUSION: This study represents no adversely effect of exogeneous gonadotropins, rFSH and uFSH, on the expression of implantation related genes. We suggest that rFSH is applicable for the assisted reproductive technology without any concern on the endometrial receptivity.

Small follicular cysts are common findings in the ovaries of prepubertal girls, and in most cases, they are of no clinical importance. Ocassionally these cysts may enlarge and continue to produce estrogen, resulting in signs of precocious sexual development and vaginal bleeding. We have experienced a case of a precocious pseudopuberty causing ovarian follicular cyst which was treated by exploratory laparotomy. we present this case with a brief review of literatures

Primary amenorrhea due to intrasella arachnoid cyst is a very rare disease and require careful and frequent evaluation because may produce intracranial hemorrhage, elevated intracranial pressure and rapid expansion. Surgical intervention is needed only when visual disturbance, hypopituitarism or enlarging lesion is shown. Thus, we present a case of primary amenorrhea due to intrasella arachnoid cyst which was resected through the transsphenoidal approach.

BACKGROUND: Biodegradable polymers have increasingly been recognized for various biological applications in recent years. Here we examined the immunostimulatory activities of the novel poly(aspartic acid) conjugated with L-lysine (PLA). METHODS: PLA was synthesized by conjugating L-lysine to aspartic acid polymer. PLA-nanoliposomes (PLA-NLs) were prepared from PLA using a microfluidizer. The immunostimulatory activities of PLA-NLs were examined in mouse bone marrow-derived dendritic cells (BM-DCs). RESULTS: PLA-NLs increased the number of BM-DCs when added to cultures of GM-CSF-induced DC generation on day 4 after the initiation of cultures. Examination of the phenotypic properties showed that BM-DCs generated in the presence of PLA-NLs are more mature in terms of the expression of MHC class II molecules and major co-stimulatory molecules than BM-DCs generated in the absence of PLA-NLs. In addition, the BM-DCs exhibited enhanced capability to produce cytokines, such as IL-6, IL-12, TNF-alpha and IL-1beta. Allogeneic mixed lymphocyte reactions also confirmed that the BMDCs were more stimulatory on allogeneic T cells. PLA- NL also induced further growth of immature BM-DCs that were harvested on day 8. CONCLUSION: These results show that PLA-NLs induce the generation and functional activities of BM-DCs, and suggest that PLA-NLs could be immunostimulating agents that target DCs.

PURPOSE: Recent development of diffusion tensor imaging enables the evaluation of the microstructural characteristics of the brain white matter. However, optimal imaging parameters for diffusion tensor imaging, particularly concerning the number of diffusion gradient direction, have not been studied thoroughly yet. The purpose of this study was to evaluate the influence of the number of diffusion gradient direction on the fiber tracking of the white matter. MATERIALS AND METHODS: 13 healthy volunteers (ten men and three women, mean age 30 years, age range 23-37 years) were included in this study. Diffusion tensor imaging was performed with different numbers of diffusion gradient direction as 6, 15, and 32, keeping the other imaging parameters constant. The imaging field ranged from 1 cm below the pons to 2-3 cm above the lateral ventricle, parallel to the anterior commissure-posterior commissure line. FA (fractional anisotropy) maps were created via image post-processing, and then FA and its standard deviation were calculated in the genu and the splenium of the corpus callosum on each of FA maps. Fiber tracking of the corticospinal tract in the brain was performed and the number of the reconstructed fibers of the tract was measured. FA, standard deviation of FA and the number of the reconstructed fibers were compared statistically between the different diffusion gradient directions. RESULTS: FA is not statistically significantly different between the different diffusion gradient directions. By increasing the number of diffusion gradient direction, standard deviation of FA decreased significantly, and the number of the reconstructed fibers increased significantly. CONCLUSION: The higher number of diffusion gradient direction provided better quality of fiber tracking.

OBJECTIVE: The clinical features and prognosis of intraductal papillary mucinous tumor (IPMT) of the pancreas are diverse. We reviewed the clinicopathologic features and surgical results of patients who were treated for IMPT. METHODS: WE retrospectively reviewed seven cases that were surgically resected and pathologically diagnosed. RESULTS: The mean patient age was 63.7 years and there were 6 (85.7%) symptomatic patients. The diagnostic accuracy of abdominal CT was 57.1% (n=4) and the was 71.4% (n=5). (Ed note: the last part made no sense. Put in the correct terms.) The final diagnosis was benign IPMT in 4 cases (57.1%), malignancy in 3 cases (42.9%, and borderline malignancy, carcinoma in situ and invasive carcinoma in one case each, respectively). Three cases each of pylorus preserving panreaticoduodectomy (42.9%) and distal pancreatectomy were performed (42.(%), respectively, and 1 pancreatic wedge resection (14.3%) was performed for 1 case. Three patients (42.9%) were found to have associated malignancies. The median follow-up duration was 10 months (range: 3-25). Four patients are still alive and 3 patients have died, but only one patient died of systemic metastasis. CONCLUSION: The clinicopathological features, treatment, and prognosis of IPMT are still unclear, but the significant possibility of malignancy and associated malignancies should always kept in mind and further study is required

Eosinophilic gastroenteritis (EG) is a rare disease characterized by massive eosinophilic infiltration of gastrointestinal tissue, peripheral eosinophilia, and nonspecific gastrointestinal symptoms. The mucosal type of EG commonly presented with malabsorption and anemia. However, the role of food allergy as a stimulus to EG has not yet been clearly defined. A 27-year-old man was referred to the Emergency Department with dyspepsia and leg swelling. The initial laboratory test should as follows: hemoglobin level, 6.4 g/dL; white blood cell count, 7,400/microL with 24.4% of eosinophil fraction; serum total protein, 3.9 g/dL; albumin level, 2.8 g/dL. Gastric endoscopy ruled out gastrointestinal bleeding showed multiple nodular raised lesions on the gastric antrum, which revealed increased eosinophilic infiltration (above 100/high power field). He had experienced nausea whenever eating beef, porks or fish. High serum specific IgE levels to offending foods (beef, 0.82 kU/L; pork, 0.83 kU/L; egg white, 0.40 kU/L; egg yolk, 0.54 kU/L; milk, 0.81 kU/L) were noted. He was instructed strictly to avoid food allergens with oral prednisolone therapy. Approximately 6 months after offending food restriction, the eosinophil count fell down to 400/microL, the hemoglobin level was returned to 11.5 g/dL and the serum albumin level was increased to 4.1 g/dL. We report a case of EG caused by multiple food allergy which leads to malabsorption and iron-deficiency anemia.

Spinal muscular atrophy(SMA) is the second most common fatal disease of childhood with autosomal dominant mode of inheritance, and in its less severe form the third most common neuromuscular disease of childhood after Duchenne muscular dystrophy. The genetic defect was found to be on the long arm of chromosome 5(5q11.2-q13.3) where many genes and microsatellite markers were missing. One of the most important genes is the Survival Motor Neuron(SMN) gene which is homozygously missing in 90% of SMA patients. Another important gene, the Neuronal Apoptosis Inhibitory Protein(NAIP) gene was found to be defective in 67% of SMA type I patients. Studies so far suggest SMA occurs when the genes on the long arm of chromosome 5 are mutated or deleted. Recently our hospital encountered 2 SMA patients of type I and II respectively. These patients both had homozygously defective SMN genes but intact NAIP genes. We are reporting these cases with bibliographic review and discussion. Korean SMA patients presumably have defects in SMN genes similar to those found in European patients, although the siginificance of NAIP genes remains to be established. SMN gene defects can be easily diagnosed using PCR and restriction enzymes, and this method could be applied towards convenient prenatal diagnosis and towards screening for family members at risk.
