  • Recent technical developments have transformed how neuroscientists can probe brain function. What was once thought to be difficult and perhaps impossible, stimulating a single set of long range inputs among many, is now relatively straight-forward using optogenetic approaches. This has provided an avalanche of data demonstrating causal roles for circuits in a variety of behaviors. However, despite the critical role that neuropeptide signaling plays in the regulation of behavior and physiology of the brain, there have been remarkably few studies demonstrating how peptide release is causally linked to behaviors. This is likely due to both the different time scale by which peptides act on and the modulatory nature of their actions. For example, while glutamate release can effectively transmit information between synapses in milliseconds, peptide release is potentially slower [See the excellent review by Van Den Pol on the time scales and mechanisms of release (van den Pol, 2012)] and it can only tune the existing signals via modulation. And while there have been some studies exploring mechanisms of release, it is still not as clearly known what is required for efficient peptide release. Furthermore, this analysis could be complicated by the fact that there are multiple peptides released, some of which may act in contrast. Despite these limitations, there are a number of groups making progress in this area. The goal of this review is to explore the role of peptide signaling in one specific structure, the bed nucleus of the stria terminalis, that has proven to be a fertile ground for peptide action.

  • An Epidemic disease is regarded as warm disease by Korean Medicine. Warm disease is highly contagious and shows an unfavorable condition, and that is characteristic of being widely prevalent. Warm disease study cope with this epidemic disease opportunely. In the Myeong[明] and Cheong[淸] Dynasty, warm disease study got into the region of Korean medicine of today and "The Sections of Warm Disease(溫病條辨)" contributed to the cause of the study was really great. "The Sections of Warm Disease" written by Ohguktong(吳鞠通) in the Cheong Dynasty are divided into the three sections of Upper burner[上焦], Middle burner[中焦] and Lower burner[下焦]. Ohguktong, dealing with the contents of Defense-aspect[衛分], Gi-aspect[氣分], Construction-aspect[營分], Blood-aspect[血分], and so forth in all "Sections of Warm Disease", made use of Seopcheonsa(葉天士)'s Defense Gi[衛氣], Construction, and Blood pattern identification with Triple burner[三焦] pattern identification and six channel pattern identification. And he, having a correct understanding of the nature of medicine, suggested in detail that the directions of medicine and described the processing according to method and the method to take medicine. To conclude, Ohguktong(吳鞠通) Tong in "The Sections of Warm Disease" not only formulated the system of the practical theory of warm disease but also solidified the foundation covering warm disease and its treatment as well, He established the new method of treatment and formula related to warm disease and made a definite distinction between cold damage[傷寒] and warm disease[溫病].

  • Background and Objectives : Branchial anomaly is a common neck pathology seen by otolaryngologist. Although there is still controversy regarding the origin, almost all surgeon agree that branchial anomalies result from incomplete involution of the branchial apparatus. Depending on its anatomic location, branchial anomalies can be classified into first, second, third and fourth anomaly. The purpose of this study is to evaluate the incidence of different categories of branchial anomalies and to determine proper method of diagnosis and treatment. Subjects and Method : A retrospective chart review was conducted for 72 patients with branchial anomalies operated on at the Korea University Anam Hospital from 1996 to 2007. The patient's sex, age, presenting symptoms, classification, site of lesion, diagnostic studies, surgical therapy and post-operative surgical complication were reviewed. Results : Patients were commonly seen in the 3rd decades. Eleven patients(15.3%) were first branchial anomalies, 52(72.2%) were second, 1(1.4%) was third, and 8(11.1%) were fourth. Of the types of anomalies, cyst were most commonly seen. In cases of 3rd and 4th branchial anomalies, barium contrast study can delineate the course of sinus or fistula. All cases was operated on for branchial anomalies, there were no major post-operative complication. Conclusion : Cervical mass and recurrent cervical infection or abscess are suspect for branchial anomalies. Especially, clinical history of dysphagia, and recurrent painful swelling in the thyroid region in young patients should raise the suspicion of 3rd and 4th branchial anomalies. Careful history, clinical examination and radiographic study were essential parts in diagnosis of branchial anomalies. Although surgical management of branchial anomalies depend on its type, nature and extent, complete excision is the major surgical procedure.

  • The purpose of this study is to identify the presence of the circulating antibodies directed toward ovarian proteins{antiovarian antibodies, AOA) and the nature of antigenic ovarian structure by comparing the binding activities to 4 types of ovarian proteins, particulated and solubilized forms of pig ovarian and granulosa cell membranes in sera of patients with premature ovarian failure(POF) and to evaluate the usefulness of circulating AOA as a follow up tool after treatment. Measurements of AOA were performed by enzyme linked immunosorbent assay(ELISA) in sera of 58 patients with POF, 51 had normal chromosomes and 7 had X chromosome abnormalities. Sera of 21 natural menopausal women and 17 castrated women were also tested and sera of 32 healthy premenopausal women were served as controls. ELISA reactivities against particulated porcine granulosa cell membrane proteins was the greatest among 4 different ovarian proteins. Fifteen(29%) of 51 POF patients with normal chromosome and 1(14.3%) of 7 POF patients with X chromosome abnormalities had AOA while none of 32 controls and 21 natural menopausal women and 17 castrated women had AOA. One POF patient with 47, XXX was identified AOA positive. The ELISA reactivities were followed up monthly up to 5 months in 4 AOA positive POF patients after estrogen-progestin{E-P) therapy. There was a decreasing tendency of the ELISA reactivities in all these patients after E-P therapy and two of them converted to AOA negative. These data suggest that antigenic structure may be components of granulosa cell membrane and the determination of circulating AOA may be useful in the follow up after treatment in patients with autoimmune POF.

  • In the ancient time wind is considered as the life . soul and the human's breath which represents essence of universal creation and the absolute power and also the messenger of the god or god's state. Greek's 'pneuma' , India's 'Brahman' and the Old Testament's 'ruach' are used to signify the wind. Also Wind(風) in traditional culture, it is related to 玄妙之道 of 花郞, the flower of youth in Shilla dynasty and sexual intercourse in shaman's dream which can be thought as Freud's libido. In this aspect we can see the connection between the wind and the libido which can be meaning of sexual desire. Ancient Chinese wrote word ‘風’ as phoenix, the god's bird, the phoenix in inscriptions on bones and tortoise carapace(甲骨文) because one can feel the wind but can’t see it. The word Ki(氣) origins from 風 therefore 風 is 氣's fundamental notion. The wind can be understood by ki which travels around the world to create all nature. And the Wind is associated with 風化, 玄鳥, 八僧舞, which are related with reproduction. In the book of change (周易) the 震巽卦 ; 雷風 come under wind which means the function of ki and also menas the 精(essence of life) of 恒久(eternity) means the reprodution ; that performs succession of life. In the Oriental Medicine 氣 is a phenomenon that appears by movement of Ki by 相火(Ministerial fire). 相火 is core of the succession of life which means preservation of descendants; therefore 風 has very similar concept with sexual desire. 風 is the beginning ki of universe and in human body aspect 風 belong to the Liver Meridian. If 風 makes movement then the Pericardium Meridian of Hand Kwolum responds and the genital organs which belongs to Liver Meridian of Leg Kwolum reproductive function by contraction and expansion. Generally 風 understood as movement and origination and this is recognized as meaning of 氣. Therefore as studied above the present writer believe m. participates closely to reproductive function.

  • Atherosclerosis is considered as a chronic inflammatory process. However, the nature of the oxidant signaling that regulates monocyte adhesion and its underlying mechanism is poorly understood. We investigated the role of reactive oxygen species on the vascular cell adhesion molecule-1 (VCAM-1) and monocyte adhesion in the cultured endothelial cells. $TNF-{\alpha}$ at a range of $1{\sim}30\;ng/ml$ induced VCAM-1 expression dose-dependently. BCECF-AM-labeled U937 cells firmly adhered on the surface of endothelial cells when the endothelial cells were incubated with $TNF-{\alpha}$ (15 ng/ml). Ten $\;{\mu}mol/L$ of SB203580, an inhibitor of p38 MAPK, significantly reduced $TNF-{\alpha}-induced$ VCAM-1 expression, compared to the JNK inhibitor ($40\;{\mu}mol/L$ of SP60015) or ERK inhibitor ($40\;{\mu}mol/L$ of U0126). Also, SB203580 significantly inhibited $TNF-{\alpha}-induced$ monocyte adhesion in HUVEC. Superoxide production was minimal in the basal condition, however, treatment of $TNF-{\alpha}$ induced superoxide production in the dihydroethidineloaded endothelial cells. Diphenyleneiodonium (DPI, $10\;{\mu}mol/L$), an inhibitor of NADPH oxidase, and rotenone $(1\;{\mu}mol/L)$, an inhibitor of mitochondrial complex I inhibited $TNF-{\alpha}-induced$ superoxide production, VCAM-1 expression and monocyte adhesion in the endothelial cells. Taken together, our data suggest that NADPH oxidase and mitochondrial ROS were involved in $TNF-{\alpha}-induced$ VCAM-1 and monocyte adhesion in the endothelial cells.

  • A murine model immunized by systemic and mucosal delivery of plasmid DNA vaccine expressing glycoprotein B (pCIgB) of pseudorabies virus (PrV) was used to evaluate both the nature of the induced immunity and protection against a virulent virus. With regard to systemic delivery, the intramuscular (i.m.) immunization with pCIgB induced strong PrV-specific IgG responses in serum but was inefficient in generating a mucosal IgA response. Mucosal delivery through intranasal (i.n.) immunization of pCIgB induced both systemic and mucosal immunity at the distal mucosal site. However, the levels of systemic immunity induced by i.n. immunization were less than those induced by i.m. immunization. Moreover, i.n. genetic transfer of pCIgB appeared to induce Th2-biased immunity compared with systemic delivery, as judged by the ratio of PrV-specific IgG isotypes and Th1- and Th2-type cytokines produced by stimulated T cells. Moreover, the immunity induced by i.n. immunization did not provide effective protection against i.n. challenge of a virulent PrV strain, whereas i.m. immunization produced resistance to viral infection. Therefore, although i.n. immunization was a useful route for inducing mucosal immunity at the virus entry site, i.n. immunization did not provide effective protection against the lethal infection of PrV.

  • Objects : Because of the nonspecific nature of symptoms in tuberculous spondylitis, a delay in the diagnosis can result in progressive neurologic deficits. The authors evaluate the clinical and the radiological results of the 10 cases of surgically treated tuberculous spondylitis. Clinical materials & Methods : We retrospectively analyzed the medical records of 10 patients with tuberculous spondylitis who were treated between February 1996 and March 2000. Six patients were female, and four were male. Mean age was 43 years old, and mean follow-up period was 20.5 months. All patients were treated with 12 months of antituberculous medication postoperatively, and were followed by complete blood count, ESR, spine X-ray and MRI. Results : The lumbar spine was involved in 5 patients, the thoracic in 4, and the thoracolumbar in one. The infected vertebral bodies were 2.8 in average. The associated lesions were pulmonary tuberculosis in 3 cases, and renal tuberculosis in one. Five patients were treated by anterior debridement and fusion with bone graft using anterior instrumentation, 2 with anterior debridement and fusion with bone graft(Hong Kong procedure only), 1 with Hong Kong procedure with posterior spinal instrumentation, and 2 were managed with posterior debridement and posterior spinal instrumentation. All patients improved after operation, and the average kyphotic angle decreased postoperatively. Postoperatively, one patient had a fistula at the operative site. Conclusion : The debridement and minimal level fusion of motion segment with instrument fixation is one of surgical option for tuberculous spondyltis to preserve the spine motion segment as much as possible. Spine instability and kyphosis were prevented by anterior and posterior spinal instrumentation. But, large number of cases and longer period follow-up study in future will be needed to confirm the long term results.

  • Objective : The purpose of this study is to investigate nucleotide sequence and extract cytotoxicity of Scolopendrae corpus. The nature and taste of Scolopendrae corpus is hot, Warm and toxic, and the effect of this is dispelling wind, anti-spasmodic action and detoxication so it has been used for C.V.A, facial palsy, sensory disorder at extremities, wounds and arthritis. Methods : Scolopendrae corpus were collected by locality on the market. They were morphologically classified. Their nucleotide sequence was investigated and compared among them. In addition, the water-alcohol extract cytotoxicity of them was studied by MTT-based cytotoxicity assay. Results : It was shown that the each Scolopendrae corpus by locality is almost identical at genetic result and is identified as Scolopendra subspinipes mutilans L. Koch. Nucleotide sequence of Scolopendra subspinipes mutilans L. Koch in this study will help to discriminate other species of Scolopendrae corpus. The water-alcohol extract of Scolopendra subspinipes mutilans L. Koch did not induce cytotoxicity on Hep G2, L929 cell and peritoneal macrophages. Besides, it did not influence nitrite production of peritoneal macrophages. These results can be used as basic data for genetic discrimination with another species of scolopendrae corpus.
