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: The purpose of this study is to analyze the clinical characteristics of anaphylaxis and anaphylactic shock caused by bee venom. METHODS: We retrospectively collected the data of the patients who experienced anaphylaxis caused by natural bee sting or acupuncture using bee venom from January 1999 to December 2008. Seventy subjects were divided into the shock and non-shock groups. The clinical characteristics, sources of bee venom, treatments and outcomes were compared between the two groups. RESULTS: The mean age of the subjects was 45.5 +/- 16.3 years old and the number of males was 44 (62.9%). There were 25 patients in the shock group and 45 in the non-shock group. The age was older (P=0.001) and females (P=0.003) were more frequent in the shock group. Transportation to the hospital via ambulance was more frequent in the shock group (p<0.001). No difference was found in species of bee between the two groups. The cephalic area, including the face, was the most common area of bee venom in both groups. Anaphylaxis caused by bee sting commonly occurred between July and October. Cutaneous and respiratory symptoms were the most frequent symptoms related to anaphylaxis. Cardiovascular and neurologic symptoms were more frequent in the shock group. The amount of intravenously administered fluid and subcutaneous injection of epinephrine were much more in the shock group than that in the non-shock group. CONCLUSION: Older age was the factors related to anaphylactic shock caused by bee venom. Further validation is needed to evaluate the gender factor associated with shock.

Hepatopulmonary syndrome is a triad that includes: hepatic dysfunction, intrapulmonary vascular dilatation and abnormal arterial oxygenation. The incidence of intrapulmonary vascular dilatations, in adults with end-stage liver disease, has been reported to be 13% to 47%, however the incidence in children is unclear and the cases in Korean children have never been reported. The hepatopulmonary syndrome may occur as a result of chronic liver disease following nonalcoholic steatohepatitis in children with hypothalamic or pituitary dysfunction. We report a case of hepatopulmonary syndrome in a 13-year- old child who had rapidly progressive liver dysfunction secondary to panhypopituitarism after craniopharyngioma resection. Careful monitoring and treatment of endocrine abnormalities and metabolic status, as well as liver function, are required in all children undergoing pituitary tumor resection.

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.

BACKGROUND: Malassezia yeasts are normal skin flora of humans. But skin colonization appear to be controversial during neonate. OBJECTIVE: We prospectively studied the distribution of Malassezia yeasts on clinically normal skin of neonates and infants for providing the basic data for proving the relationship of Malassezia yeasts and pathogenesis of the diseases of neonates and infants. METHODS: A total of 200 subjects were studied using the direct smear test with 20% Parker ink/KOH solution. The numbers of the Malassezia yeasts per high power field were counted according to a bacterial index of lepra bacilli in patients of leprosy. In order to identify risk factors for the distribution of Malassezia yeasts, we compared sex, mode of delivery, gestational age, birthweight during the first week of life by statistical method of the logistic regression. RESULTS: Of the 200 neonates and infants under 12 weeks, 121 (60.5%) revealed Malassezia yeasts in at least a part of five examined sites. The prevalence of Malassezia yeasts was increased according to the age. No association was found between the incidence of Malassezia yeasts and sex, mode of delivery, gestational age, birth weight. CONCLUSION: We conclude that Malassezia yeasts colonize on the skin of neonates and infants.
