To elucidate the present forest avifauna of Jangsoo county, bird censuses were conducted at Mt. Seongsu, Mt. Bonghwang, and Mt, Mabong from April to July, 2006. A total of 48 bird species was recorded. Among them, 36 species were estimated prospective breeding species. The most of dominant species in this area was Paradoxornis webbianus. The legal protected birds listed by Ministry of Environment were 2species : Falco peregrinus(endengerd species classⅠ) and Charadrius placidus(endengerd species classⅡ). And also, natural monuments designated by Cultural Heritage Administration were six species : Falco peregrinus, Accipiter soloensis, Falco tinnunculus, Ninox scutulata, Otus scops and Aix galericulata

Sister-chromatid exchanges measured in the peripheral lymphocytes of 15 non-smoking medical students after exposure to formaldehyde during 24-week anatomy class showed a small but significant (p=0.0468) increase when compared with samples obtained from the same individuals immediately before exposure. Mean frequencies of sister-chromatid exchange of cultured peripheral lymphocytes were 5.40±0.24 from the samples before exposure and 5.87±0.22 from the same samples after exposure. Breathing-zone air samples collected by formaldehyde monitoring kit with digital colorimeter(SKC) showed a mean concentration of 0.72±0.02 ppm formaldehyde.

Intussusception is a rare cause of postoperative intestinal obstruction in adults. Many retrograde intussusceptions occur during the period following gastrectomy. A 77-year-old woman visited our hospital because of detected gastric adenocarcinoma. She received radical total gastrectomy with Roux-en-Y esophagojejunostomy. On the fifth postoperative day, she complained of abdominal pain, and we found leakage at the esophagojejunostomy site and dilatation of the Roux limb and the afferent limb of the jejunojejunostomy. Emergency surgery was performed. Retrograde jejunojejunal intussusception accompanied with a nasojejunal feeding tube was found at the efferent loop of the jejunojejunostomy. No ischemic change was found; therefore, manual reduction and primary repair of esophagojejunostomy was performed. She was discharged without complications on the 23rd re-postoperativeday. We suggest that the nasojejunal feeding tube acted as a trigger of intussusception because there was no definitive small bowel mass or postoperative adhesion. We present our findings here along with a brief review of the literature.

<P>Although the level of serum amyloid A has been reported to be up-regulated during inflammatory response, the role of serum amyloid A on the regulation of inflammation and immune response has not been elucidated. We found that serum amyloid A stimulated the production of tumor necrosis factor (TNF)-alpha and interleukin (IL)-10, which are proinflammatory and anti-inflammatory cytokines, respectively, in human monocytes. Low concentrations of serum amyloid A stimulated TNF-alpha production with maximal activity at 6 h after stimulation, whereas high concentrations of serum amyloid A stimulated IL-10 production with maximal activity at 12 h. The activations of the two cytokines by serum amyloid A occurred at both the transcription and translational levels. Signaling events induced by serum amyloid A included the activation of two mitogen-activated protein kinases (extracellular signal-regulated kinase and p38 kinase), which were found to be required for TNF-alpha and IL-10 production, respectively. The stimulation of formyl peptide receptor-like-1-expressing RBL-2H3 cells, but not of vector-expressing RBL-2H3 cells with serum amyloid A, induced mitogen-activated protein kinases activation and the accumulation of the RNAs of these two cytokines. Together, our findings suggest that serum amyloid A modulates contrary immune responses via formyl peptide receptor-like 1, by inducing TNF-alpha or IL-10, and demonstrate that extracellular signal-regulated kinase and p38 kinase play counteracting roles in this process.</P>

A Cu(In,Ga)Se2 light-absorbing layer was prepared by a three-stage process employing the evaporation of In2Se3, Ga2Se3, and Cu2Se. The Cu content in the layer was adjusted by controlling the third-stage evaporation time. A sturdy n-CdS/p-CIGS junction was realized when the Cu content in Cux(In0.66Ga0.34)Se2 was approximately 0.87, and the diode and photovoltaic parameters were also improved. At this condition, the doping concentration and junction depth were 7×1015cm-3 and approximately 650 nm, respectively. The current collection efficiency in red light and longer wavelengths was improved in the sturdy junction. The efficiency of CdS/Cu(In,Ga)Se2 solar cell was 13.4% when the composition of CIGS film was Cu0.87(In0.66Ga0.34)Se2.

Tuberculosis infection of skeletal muscle is rare even in countries in which tuberculosis is a relatively common disease. Because tuberculosis of muscle is almost always secondary to underlying tuberculosis of the bone or adjacent joint, hematogenous tuberculosis of skeletal muscle is extremely rare. Therefore, We report a case of hematogenous tuberculosis of skeletal muscle with the review of literatures. A 79-year-old man presented with a history of left shoulder pain, edema, fever and chill. MRI showed inflammatory changes of infraspinatus and deltoid muscle. The histopathology of skeletal muscle showed granulomas surrounded by epithelioid cells and Langhans` giant cells. Mycobacterium tuberculosis was grown from the specimens of sputum, pleural fluid and muscle tissue. The patient improved on anti-tuberculosis treatment.

The objective of this study is to prepare ketoprofen (KP) - poly(ethylene glycol) (PEG) conjugates and to investigate their degradation kinetics. KP-PEG conjugates were synthesized from KP and PEG methylester by esterification in the presence of DCC. The KP-PEG conjugates (KPEG) were characterized by IR and ^1H-NMR spectroscopy. The hydrolysis of KPEG with time was studied using HPLC by simultaneous quantification of KP and KPEG. The hydrolysis rate constant was high at low and high pHs, and showed minimum at pH 4 and 5. As the size of KPEG increase, hydrolysis rate increased. The slope of degradation rate profile suggests that catalytic reaction seems to occur by specific acid/base catalysis. These results suggest that KPEG could be used as a prodrug for KP, which releases KP slowly in the body.
