목적: 통각과 진동감각 역치검사 및 수부와 수지의 악력, 그리고 수지의 운동기능검사(태평) 등과 근로자들이 호소했던 증상에 대한 HAVS의 스톡홀름 워크샵 분류와의 관련성을 통해 좀 더 객관화된 신경학적 조기검사 방법을 찾고 타당성을 검증하고자 하였다. 방법: 2000년 1월부터 2007년 12월까지 수부진동에 폭로되고 수부의 불편함을 호소하여 진동 장해에 대한 검사를 시행한 497명의 근로자를 대상으로 하였다. 일차적으로 문진을 통해 직업력에 대해 알아보고 과거력을 조사했다. 대상자들의 스톡홀름 워크샵 분류에 따른 소견을 확인하고 수부의 말초 순환기능 검사(손톱압박, 수지피부 온도), 신경기능 검사(통각과 진동각 역치), 운동기능 검사(악력, 태평) 등을 시행하였다. 다른 질환의 감별을 위한 몇 가지 이학적 검사를 실시하고 스톡홀름 워크샵 분류에 따른 검사 결과들을 분석하였다. 결과: 사용 도구는 그라인더 단독 사용이 265명 (67.3%)으로 가장 많았으며 평균 노출 연수는 14.8년이었다. 통각과 진동감각에서 스톡홀름 워크샵 분류 단계에 따른 역치가 증가하는 경향을 보였으나 통각은 양측 모두 통계적인 유의성이 없었고, 진동감각은 125와 250 Hz에서 양측 모두 유의했다(p=0.006-0.038). 수부와 수지의 악력은 단계가 올라갈수록 감소하는 경향을 보였지만 수부와 수지 모두 우측에서만 통계적으로 유의했다 (p=0.041, p<0.01, p=0.034). 태평 첫수는 단계가 올라 가면서 전반적으로 태핑 첫수가 감소하였으며 좌측에서만 통계적으로 유의했다(p=0.002-0.019). 결론: 본 연구는 수부 진동 노출자들의 수부 불편함에 대한 신경계통을 초기에 정량적으로 객관화하여 진단할 수 있는 단일 방법은 아직 없으며 일상생활의 불편함과 스톡홀름 워크샵 분류 등을 통한 주관적인 증상에 더하여 수지 통각과 진동감각 역치검사, 수부와 수지 악력검사, 운동기능검사(태핑) 등을 통합하면 초기에 객관적으로 진단하는 것이 가능할 것으로 판단된다. Objectives: In order to determine find out the best methods for a more objective detection of neurologic abnormality in early hand ann vibration syndrome(HAVS), early with analyzing the validity of each of the detection methods was analyzed. We evaluated the relationships between the sensorineural stage of Stockholm-revised vibration syndrome classification and the results of several tests. Methods: 497 workers were investigated for symptom, exposure duration, the types of tools used, and medical history from January 2000 to December 2007. Pain sense threshold, vibrotactile threshold, hand grasp force, finger grasp force, and a finger tapping frequency test were performed by the workers. Results: The grinder(67.3%) was the most commonly used tool and the mean exposure duration was 14.8 years. Although the pain sense and vibrotactile threshold level tended to increase according to sensorineural stage of the Stockholm classification, there was statistically significant difference in the vibrotactile threshold of 125, 250 Hz (P=0.006~0.038) but not in the pain sense threshold. Hand and finger grasp force tended to decrease according to the sensorineural stage of Stockholm classification and there was statistically significant difference(P=0.041, <0.001, 0.034) only on the right hand side. The tapping frequency also generally decreased according to the sensorineural stage of the Stockholm classification and there was statistically significant difference (P=0.002~0.019) only on the left hand side. Conclusions: Although there is no single standardized method that can objectively diagnose the Sensorineural component of early HAVS early, the combination of subjective symptoms, the sensorineural stage of Stockholm classification, the pain and vibrotactile threshold test, the hand and finger grasp force, and the finger agility (tapping) test can objectively detect sensorineural component of HAVS early.

<P>In developing countries, <I>Shigella</I> is a primary cause of diarrhea in infants and young children. Although antibiotic therapy is an effective treatment for shigellosis, therapeutic options are narrowing due to the emergence of antibiotic resistance. Thus, preventive vaccination could become the most efficacious approach for controlling shigellosis. We have identified several conserved protein antigens that are shared by multiple <I>Shigella</I> serotypes and species. Among these, one antigen induced cross-protection against experimental shigellosis, and we have named it pan-<I>Shigella</I> surface protein 1 (PSSP-1). PSSP-1-induced protection requires a mucosal administration route and coadministration of an adjuvant. When PSSP-1 was administered intranasally, it induced cross-protection against <I>Shigella flexneri</I> serotypes 2a, 5a, and 6, <I>Shigella boydii</I>, <I>Shigella sonnei</I>, and <I>Shigella dysenteriae</I> serotype 1. Intradermally administered PSSP-1 induced strong serum antibody responses but failed to induce protection in the mouse lung pneumonia model. In contrast, intranasal administration elicited efficient local and systemic antibody responses and production of interleukin 17A and gamma interferon. Interestingly, blood samples from patients with recent-onset shigellosis showed variable but significant mucosal antibody responses to other conserved <I>Shigella</I> protein antigens but not to PSSP-1. We suggest that PSSP-1 is a promising antigen for a broadly protective vaccine against <I>Shigella</I>.</P>

Background: Shift work is closely related with workers" health. In particular, sleep is thought to be affected by shift work. In addition, shift work has been reported to be associated with the type or direction of shift rotation, number of consecutive night shifts, and number of off-duty days. We aimed to analyze the association between the night shift rotation interval and the quality of sleep reported by Korean female shift workers. Methods: In total, 2,818 female shift workers from the manufacturing industry who received an employee physical examination at a single university hospital from January to August in 2014 were included. Subjects were classified into three groups (A, B, and C) by their night shift rotation interval. The quality of sleep was measured using the Korean version of the Pittsburgh Sleep Quality Index (PSQI). Descriptive analysis, univariate logistic regression, and multivariate logistic regression were performed. Results: With group A as the reference, the odds ratio (OR) for having a seriously low quality of sleep was 1.456 (95% CI 1.171–1.811) and 2.348 (95% CI 1.852–2.977) for groups B and C, respectively. Thus, group C with the shortest night shift rotation interval was most likely to have a low quality of sleep. After adjustment for age, obesity, smoking status, alcohol consumption, exercise, being allowed to sleep during night shifts, work experience, and shift work experience, groups B and C had ORs of 1.419 (95% CI 1.134–1.777) and 2.238 (95% CI 1.737–2.882), respectively, compared to group A. Conclusion: Our data suggest that a shorter night shift rotation interval does not provide enough recovery time to adjust the circadian rhythm, resulting in a low quality of sleep. Because shift work is influenced by many different factors, future studies should aim to determine the most optimal shift work model and collect accurate, prospective data.

<P> Kim, J. H., Jung, E. Y., Hong, Y. H., Bae, S. H., Kim, J. M., Noh, D. O., Nozaki, T., Inoue, T. and Suh, H. J. 2012. Short Communication: Pet foods with yeast hydrolysate can reduce body weight and increase girth in beagle dogs. Can. J. Anim. Sci. 92: 207-210. Beagle dogs fed pet foods that included yeast hydrolysate (YH) were used in the present study to assess the possible use of YH as a functional anti-obesity ingredient in pet food. The change in weight and girth in the YH groups was significantly (P@@<@@0.05) lower than that in the control. Plasma malondialdehyde was significantly (P@@<@@0.05) lower in the YH groups compared with that in the control. Plasma levels of the reduced form of glutathione were significantly (P@@<@@0.05) higher in the YH groups than those in the control. Therefore, YH could be recommended as an anti-obesity functional feed source for dogs. </P>

New lipophilic Crown-4 compounds of 16-membered rings containing furan (neutral carrier,I), tetrahydrofuran (neutral carrier,II) and lithium complex of the latter (neutral carrier,III) have been synthesized and tested as the active sensors for lithium ion in poly(vinyl chloride) (PVC) membrane electrode, in the presence and absence of an anion excluder, tetrakis(4-chloro-phenyl)borate (KTClPB), 2-nitrophenyl phenyl ether (NPPE), tris(2-ethylhexyl)phosphate (TEHP), o-nitrophenyl octyl ether (NPOE), dioctyl adipate (DOA), bis(2-ethylhexyl)adipate (BEHA), di-n-octylphenyl phosphonate (DOPP) were used as plasticizing solvent mediators. The electrode response function had a nearly Nernstian slope of 54-61 mV per decade (25$^{\circ}$C) within the concentration range of $10^{-1}-10^{-4}$ M LiCl and the detection limits for all electrodes were ca. $5{\times}10^{-4}$ M. The response time of the electrode was faster at the higher lithium concentration and the response of the electrode was stable for longer than 6 months. The sensor membranes exhibit improved response times and increased lifetimes as compared to the system described earlier.
