Objectives:Hypothalamic-Pituitary-Adrenocortical(HPA) system dysregulation plays an important role in the pathophysiology of major depressive disorder. Medically unexplained somatic symptoms comprised the predominant complaints of korean patients with major depressive disorder. It might be related to dysregulation of HPA system and somatic symptoms. The aim of this study was to investigate the association between Hamilton Depression Rating Scale severity and the Plasma Adrenocorticotropic Hormone(ACTH) & Serum Cortisol level in Korean patients with major depressive disorder. Methods:Our study design was prospective. A total 111 hospitalized patients with major depressive disorder (DSM-IV) at Anam Hospital, Korea University Medical Center between Jan 2009 and May 2011 were selected. Hamilton Depression Rating Scale was measured by psychiatrist. Plasma ACTH, Serum Cortisol levels were analyzed at the time of admission. Results:There are significant correlations(p<0.05) between Hamilton Depression Rating Scale of somatic component(HAM-D 11-15 item) and Plasma ACTH and Serum Cortisol level. However, other HAM-D sub items were not significantly correlated with Plasma ACTH and Serum Cortisol level except somatic component. Conclusion:Our Study results suggest that hyperactivity of HPA axis might be correlation with somatic symptoms in korean patients with major depressive disorder.

<P>Abdominal pain may precede the characteristic varicella skin lesions in immunocompromised patients with visceral varicella. The absence of skin lesions may delay timely diagnosis and treatment of varicella for those patients. Furthermore, abdominal imaging findings to provide information to diagnose visceral varicella have rarely been reported. Varicella was diagnosed in a 5-year-old boy with acute lymphoblastic leukemia complaining of fever and abdominal pain followed by papulovesicular skin lesions. Later, the patient was found to have rapidly progressive acute hepatitis, and abdominal computed tomography showed multiple hypodense hepatic nodules. The patient was treated with intravenous acyclovir, intravenous immunoglobulin, and empirical antibiotic and antifungal therapy. However, his fever and abdominal pain persisted, and a laparoscopic liver biopsy was performed to differentiate other causes of the persisting symptoms. Eventually, the patient was diagnosed with visceral varicella based on histopathologic findings. In conclusion, visceral varicella should be considered in immunocompromised patients with abdominal pain and multiple hypodense hepatic nodules on abdominal imaging studies. However, bacteria, fungi, and tuberculosis can produce similar imaging findings; therefore, a biopsy may be necessary in patients not responding to antiviral therapy.

$TiO_2$ nanostructures with various morphologies like cubes, spheres, hexahedral pillars and spherical tubes were synthesized by microwave-assisted hydrothermal process. Each structure was obtained by changing the relative concentrations of titanium tetraisoproxide (TTIP), tetrabutylammonium hydroxide (TBAH) and ethanol. Scanning electron microscopy (SEM), transmission electoron microscopy (TEM), X-ray diffraction and Brunauer-Emmett-Teller (BET) surface area analysis were used to characterize the synthesized $TiO_2$ nanostructures. From these results, it has been proved that $TiO_2$ structure could be controlled to have specific morphology, size, surface area, pore volume and pore size distribution.

It was demonstrated that ECD MS can be successfully applied to Bovine ubiquitin (8.6 kDa, 76 amino acids) and Pseudomonas aeruginosa azurin (13.9 kDa, 128 amino acids, 1 disulfide bond) cations using photoelectrons emitted by irradiating a 266 nm UV laser light on the edge of an ion cyclotron resonance (ICR) cell trapping plate hole. The photoelectron ECD method cleaved protein backbone bonds as effectively as conventional ECD MS methods that employed a tungsten (W) wire or heated dispenser cathode as an electron source. This method offers the advantage of providing electrons for ECD MS without an apparent electron source. Key Words : 266 nm UV laser, Electron capture dissociation (ECD), Ubiquitin, Azurin, FTICR MS
