To improve the therapeutic method for mastitis, treatment effect of chitosan pharmacopuncture was examined in three milking goats(A,B and C). Mastitis was artificially induced in two milking goats(A and B) and one goat(C) was naturally infected case with mastitis. The acupoint used was Yang-Ming and chitosan suspensions(provided from Tottory University, Japan: 30㎎ of chitosan/㎖)were injected to the acupoint with 5㎖/time for 3 days, respectively. As for the change of somatic cells in milk along with chitosan pharmacopuncture, they showed a decreasing tendency after increase on the 3rd day in all udders of B. In addition, as for the change of total leukocyte counts of peripheral blood with chitosan pharmacopuncture, they showed a decreasing tendency after increase on the 3rd day in B and C except A which showed a increasing tendency until on the 7th day. In the change of neutrophil/lymphocyte(N/L) ratio, increasing tendency was seen in A and C but increasing tendency after slight decrease was observed in B. Further, in the change of serum total protein and A/G ratio, serum total protein content was decreased after slightly increase on the 3rd day in A, and they were decreased after increase until on the 7th day in B and C, respectively. As for the change of A/G ratio, different pattern increasing tendency was shown in A, B and C.

The objective of this study is to test for thermal conductivity of architecture insulation materials in domestic buildings with environmental condition change. In study, we measured change of thermal conductivity with test temperature change, long-time leaving and change of contained water rate. For long-time leaving test, the specimens of building insulation materials were kept in test conditions, which were influenced by the outside environment. The results of the study show 1) the contained water rate of artificial mineral fiber insulations was big for others, 2) thermal conductivity rose as test temperature(median) grew up and 3) the extruding insulations and hardened Urethane foam changed thermal conductivity with environmental condition and time elapse.

Objective ; The aim of this study was to investigate the effect of Scalp acupuncture on recovery of motor disorders in stroke patients. Methods ; Twenty two patients with poststroke-hemiplegia were randomized into two groups. Ten patients(test group) treated by 2 methods-Scalp acupuncture and body acupuncture. The other twelve patients(control group) treated only by body acupuncture. The activity of daily living was measured with a National Institutes of Health stroke scale(NIHSS) and Modified Barthel Index(MBI). The therapy was performed one a day for 2 weeks. Results ; In terms of score of NIHSS, the test group showed statistically meaningful decrease after 2 week treatment, but the control group showed statistically meaningful decrease after 1 week(p<0.05). And in terms of score of MBI, the test group did not show statistically meaningful increase but the control group showed statistically meaningful increase after 1 week(p<O.05). There was no statistically meaningful difference after 1 and 2 week treatment between the groups. Conclusions ; These results support that test group has almost same effectness compared with control group in improvement of the activity of daily living of poststroke-hemiplegic patients.

Purpose : This study was to evaluate the beam quality of intraoral X-ray equipments used at Yonsei University Dental Hospital (YUDH) using the half value layer (HVL) and the characteristic curve of intraoral standard X-ray film. Materials and Methods : The study was done using the intraoral X-ray equipments used at each clinical department at YUDH. Aluminum filter was used to determine the HVL. Intraoral standard film was used to get the characteristic curve of each intraoral X-ray equipment. Results : Most of the HVLs of intraoral X-ray equipments were higher than the least recommended thickness, but the REX 601 model used at the operative dentistry department and the X-707 model used at the pediatric dentistry department had HVLs lower than the recommended thickness. The slopes of the characteristic curves of films taken using the PANPAS 601 model and REX 601 model at operative dentistry department, the X-705 model of prosthodontic dentistry department, and the REX601 model at the student clinic were relatively low. Conclusion : HVL and the characteristic curve of X-ray film can be used to evaluate the beam quality of intraoral X-ray equipment. In order to get the best X-ray films with the least radiation exposure to patients and best diagnostic information in clinical dentistry, X-ray equipment should be managed in the planned and organized fashion.

<P>We have synthesized gallium oxide (Ga2O3) nanomaterials at two different growth temperatures on iridium (Ir)-coated substrates by thermal evaporation of GaN powders. The products consist mainly of nanobelts, with some additional nanosheets. The nanobelts were of a single-crystalline monoclinic Ga2O3 structure. The broad emission photoluminescence band of 900°C-products had a different peak position from that of the 970°C-products.</P>

<P><B>Abstract</B></P> <P>Embedding chemical sensors into mobile devices is an emerging demand in modern information converged technology. The unbearable power consumption to raise the temperature of chemoresitive-type chemical sensors makes it impossible for them to be embedded regardless of their peculiar sensing properties such as low cost, miniaturization, high response, and excellent stability and robustness. In this study, self-heated nanowire sensors were prepared by exploiting the synergic effect of the core–shell structure and catalytic nanoparticles. As a prototype approach, Pt nanoparticle-functionalized SnO<SUB>2</SUB>–ZnO core–shell nanowires were synthesized, demonstrating extremely striking performance and characteristics. Thicker ZnO shell showed the larger self-heating and higher sensor response. The sensors exhibited excellent selectivity for toluene gas, with negligible responses to other reducing gases. This one possessed a considerable sensing performance at room temperature, even without a significant self-heating. The self-heated sensing of the novel core–shell nanowires developed required only an extremely low power consumption of 31μW, suggesting their potential in applications as sensors embedded into mobile devices.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Self-powered sensor based on Pt nanoparticle–functionalized core–shell nanowires is prepared. </LI> <LI> Selective toluene sensing is due to core–shell structure and catalytic nanoparticles. </LI> <LI> The self-powered sensing allowed an extremely low power consumption of 31μW at 5V. </LI> </UL> </P>

<P>S100A8/A9 has been suggested as a marker of disease activity in patients with adult-onset Still’s disease (AOSD). We evaluated the clinical significance of S100A8/A9 as a biomarker and its pathogenic role in AOSD. Blood samples were collected prospectively from 20 AOSD patients and 20 healthy controls (HCs). Furthermore, skin and lymph node biopsy specimens of AOSD patients were investigated for S100A8/A9 expression levels via immunohistochemistry. Peripheral blood mononuclear cells (PBMCs) of active AOSD patients and HCs were investigated for S100A8/A9 cell signals. S100A8/A9, interleukin-1β (IL-1β), and tumor necrosis factor-α (TNF-α) levels in active AOSD patients were higher than those of HCs. S100A8/A9 levels correlated positively with IL-1β, TNF-α and C-reactive protein. The inflammatory cells expressing S100A8/A9 were graded from one to three in skin and lymph node biopsies of AOSD patients. The grading for S100A8/A9 was more intense in the skin lesions with karyorrhexis, mucin deposition, and neutrophil infiltration. Like lipopolysaccharide (LPS), S100A8/A9 induced phosphorylation of p38 and c-Jun amino-terminal kinase (JNK) in PBMCs, suggesting that S100A8/A9 activates Toll-like receptor 4 signaling pathways. These findings suggest that S100A8/A9 may be involved in the inflammatory response with induction of proinflammatory cytokines and may serve as a clinicopathological marker for disease activity in AOSD.</P>
