PURPOSE: Enterovirus infection in children can manifest various disease and enterovirus have many serotypes. This study was aimed to investigate neurologic manifestations according to serotypes of enterovirus in pediatric inpatients in Incheon. METHODS: We collected the stool samples from the admitted pediatric patients in Inha University Hospital from January 2015 to September 2016. Enterovirus detection and serotypes identification were performed by real-time reverse transcriptase polymerase chain reaction (RT-PCR) and semi-nested RT-PCR. RESULTS: A total of 527 samples were collected during study period and 170 patients (32.2%) were diagnosed with enterovirus infections. Genetic sequences of enteroviruses were identified: echovirus 18 (50, 40.5%), enterovirus 71 (12, 9.6%), coxakievirus A10 (10, 8.0%), echovirus 6 (7, 5.6%). Virus in patient with meningitis were identified: echovirus 18 (15, 75%), coxakievirus B5 (2, 10%), enterovirus 71 (2, 10%), and echovirus 6 (1, 5%). Neurologic manifestations of echovirus 18 are headache (15, 30%), vomiting (17, 34%), meningeal irritation sign (10, 20.0%). And enterovirus 71 have headache (3, 25%), vomiting (3, 25%), meningeal irritation sign (2, 16.0%), seizure (1, 8.3%), neurologic sequelae (1, 8.3%). Echovirus 18 and neurologic manifestation have a statistically significant correlation with other serotypes (r=0.701, P < 0.01) CONCLUSION: Echovirus 18 infection was more prominent in neurological symptoms than in other serotypes. The major serotype of meningitis was echovirus 18 but there was no reported neurologic sequelae. Enterovirus infection has different neurological symptoms, depending on the serotypes.

Intracranial headaches, including migraines, are mediated by nociceptive activation of the trigeminal nucleus caudalis (TNC), but the precise mechanisms are poorly understood. We previously demonstrated that selective blockage of spinal sigma-1 receptors (Sig-1R) produces a prominent antinociceptive effect in several types of pain models. This study evaluates whether the Sig-1R antagonist (BD1047) has an antinociceptive effect on capsaicin (a potent C-fiber activator) induced headache models in rats. Intracisternal infusion of capsaicin evoked pain behavior (face grooming), which was significantly attenuated by BD1047 pretreatment. BD1047 consistently reduced capsaicin-induced Fos-like immunoreactivity (Fos-LI), a neuronal activator, in the TNC in a dose-dependent manner. Moreover, capsaicin-induced phosphorylation of N-methyl-D-aspartate receptor subunit 1 was reversed by BD1047 pretreatment in the TNC. These results indicate that the Sig-1R antagonist has an inhibitory effect on nociceptive activation of the TNC in the capsaicin-induced headache animal model.

BACKGROUND/AIMS: Simvastatin has dramatically reduced cardiovascular disease due to elevated cholesterol. The human multidrug resistance 1 gene (MDR1) encodes a 170-kDa transmembrane glycoprotein (P-glycoprotein), which plays an important role in regulating the absorption, distribution, and excretion of simvastatin. To clarify the effects of the MDR1 gene polymorphism on simvastatin pharmacokinetics, we investigated whether there is an association between genotype and the pharmacokinetic parameters for simvastatin. METHODS: Thirty-one healthy unrelated Korean volunteers were genotyped for MDR1. Genomic DNA from blood was analyzed using the polymerase chain reaction (PCR) and restriction fragment length polymorphism (RFLP). Following an overnight fast, all of the subjects took a single 60-mg oral dose of simvastatin. Venous blood samples were taken for 12 hours after the oral drug intake. A statistical analysis of the MDR1 genotype and pharmacokinetic parameters of simvastatin was performed. RESULTS: The mean Tmax of the 1236TT genotype was significantly higher than that of CT and CC (p=0.02). The mean AUC0-12h of 3435TT was also significantly higher, compared with CT and CC (p=0.01). No significant difference was observed between the MDR1 single nucleotide polymorphism (SNP) for G2677A/T and the pharmacokinetic parameters. CONCLUSIONS: These findings suggest that polymorphic MDR1 genes are important in the inter-individual variation of the disposition of simvastatin in humans. s

BACKGROUND: Extracellular nucleotides act as agonists to regulate a broad range of physiological processes by interacting with P2 receptors in various tissues including the kidney tubules. This study was undertaken to evaluate the effect of P2 receptor activation on PTH-dependent regulation of phosphate transport in the renal proximal tubular cells. METHODS: Proximal tubular cells were isolated from the rabbit kidney and grown as monolayers on 24 well culture plates. Phosphate uptake was determined by measuring the uptake of radiolabeled phosphate into cell monolayers. Cyclic AMP content was determined by radioimmunoassay using [3H]cAMP assay kit. RESULTS: Activation of P2 receptors with ATP exerted differential effects on phosphate uptake and cAMP generation. In the absence of PTH, it inhibited phosphate uptake and stimulated cAMP generation. In contrast, in the presence of PTH, it attenuated PTH-induced stimulation of cAMP generation and inhibition of phosphate uptake. The profile of the effects of different P2 agonists suggested that P2Y1- and P2Y2-like receptors are involved in the effects of ATP. The effect of ATP to interfere with the PTH-induced regulation was significantly blocked by calphostin C, pertussis toxin or PKC-depletion, whereas, the effects of ATP in the absence of PTH were abolished by indomethacin. CONCLUSION: Our results suggest that PKC-dependent modification of Gi proteins and, subsequently, reduced responsiveness of adenylate cyclases is responsible for the attenuating effect of ATP on the PTH-dependent regulation of phosphate transport in rabbit proximal tubule cells.

BACKGROUND: Photodynamic therapy is a viable option for lung cancer treatment, and many studies have shown that it is capable of inducing cell death in lung cancer cells. However, the precise mechanism of this cell death has not been fully elucidated. To investigate the early changes in cancer cell transcription, we treated A549 cells with the photosensitizer DH-I-180-3 and then we illuminated the cells. METHODS: We investigated the gene expression profiles of the the A549 lung cancer cell line, using a DEG kit, following photodynamic therapy and we evaluated the cell viability by performing flow cytometry. We identified the genes that were significantly changed following photodynamic therapy by performing DNA sequencing. RESULTS: The FACS data showed that the cell death of the lung cancer cells was mainly caused by necrosis. We found nine genes that were significantly changed and we identified eight of these genes. We evaluated the expression of two genes, 3-phosphoglycerate dehydrogenase and ribosomal protein S29. The expressed level of carbonic anhydrase XII, clusterin, MRP3s1 protein, complement 3, membrane cofactor protein and integrin beta 1 were decreased. CONCLUSION: Many of the gene products are membrane-associated proteins. The main mechanism of photodynamic therapy with using the photosensitizing agent DH-I-180-3 appears to be necrosis and this may be associated with the altered production of membrane proteins.

Familial adenomatous polyposis (FAP) is characterized by large numbers of adenomatous polyps in the colon and inherited as an autosomal dominant disease. Gardner's syndrome is a form of FAP accompanied by extra-colonic tumors and desmoid tumors. Desmoid tumors are rare, and benign tumors characterized by fibroblastic proliferation of fascial and musculoaponeurotic components. There is an approximate 1,000 times higher incidence of desmoid tumors in patients with FAP compared with the general population. Desmoid tumors in Gardner's syndrome occur in the small bowel mesentery in 80% of all cases, and the other 20% in the abdominal wall or the extremities. Almost all cases of desmoid tumors in Gardner's syndrome were incidentally found after prophylactic total proctocolectomy for colon cancer prevention in the patients with FAP. We report a case of Gardner's syndrome associated with codon 1099 mutation of the adenomatous polyposis coli gene, in which the patient was initially found to have desmoid tumors and subsequently diagnosed as FAP by screening colonoscopy.
