BACKGROUND: It is reported that abnormal eating behavior is more frequent in the group of weight control than those of no control. Repeated and chronic binge eating behavior has associations with impaired work and social functioning, overconcerns with body shape and weight. The purpose of this study is to investigate the degree of abnormal eating behavior according to weight management, depression level and obesity. METHODS: From June 1999 to July 1999, we collected self record questionnaire including body mass index(BMI), Beck Depression Inventory(BDI), Eating Attitude Test(EAT) from 1292 students of one girl's high school in Seoul. Study subjects were divided by BMI, the set point was 25 kg/m2. EAT score associated with weight control, BMI, BDI, smoking and alcohol was assessed by multiple linear regression. Study subjects were also grouped by the existence of the history of weight management behavoir, then BMI, EAT score and BDI in each subgroups was assessed by t test. RESULTS: Obese students were 42, whereas those of BMI under 25 kg/m2 were 1191. BDI score ranging from 5 to 20 were 940, 21 to 63 were 179. The EAT score has significant relevance to the history of weight control, BMI, and BDI score in order. The EAT score and BMI were higher in the subjects who experienced various modes of weight control (48.41+/-14.47 vs 33.63+/-12.52 in EAT, 20.34+/-2.26 vs 18.72+/-1.89)(p<0.01). CONCLUSION: EAT score was associated with weight control, BMI and BDI. EAT score and BMI were higher in weight control samples.

There are so many differences between the elderly patients and the younger patients in the aspects of a causes and the clinical course of spontaneous intracerebral hemorrage (ICH). As the mean life-time of a general population goes longer, the incidence of spontaneous ICH increases but the aggressive support in ICH is withdrawn more commonly and a prognosis of ICH becomes poor. Therefore, a prevention of ICH and a strict control of hypertension is very very important.

Background and Objectives: The directed differentiation of pluripotent stem cells into motor neurons is critical for the development of disease modelling and therapeutics to intervene degenerative motor neuron diseases. Cell surface receptor Cdo functions as a coreceptor for Sonic hedgehog (Shh) with Boc and Gas1 in the patterning of ventral spinal cord neurons including motor neurons. However, the discrete function of Cdo is not fully understood. Methods: and Results: In this study, we examined the role of Cdo in motor neuron generation by utilizing in vitro differentiation of Cdo＋/＋ and Cdo−/− embryonic stem cells (ESCs). In response to Shh, Cdo−/− ESCs exhibited impaired expression of motor neuron specification markers while dorsal interneuron specification markers were significantly increased, compared to Cdo＋/＋ ESCs. Reactivation of Shh signalling pathway with Smoothened (Smo) agonist (SAG) restored motor neuron specification in Cdo−/− ESCs. In addition, electrophysiological analysis revealed the immature electrical features of Cdo−/− ESCs-derived neurons which was restored by SAG. Conclusions Taken together, these data suggest that Cdo as a Shh coreceptor is required for the induction of motor neuron generation by fully activating Shh signalling pathway and provide additional insights into the biology of motor neuron development.

BACKGROUND: The injury by a nerve ligation produces a mechanical allodynia. The antiallodynic effect resulted from intrathecal administration of the adenosine analogues has been well known. ATP-sensitive potassium channel blockers have been known to reverse the effect of some antinociceptive drugs in animal and human studies. Therefore, the present study is to assess the relationship between antiallodynic effect of N6-(R)-phenylisopropyl adenosine (R-PIA) and mitochondrial ATP-sensitive potassium (mKATP) channel in a neuropathic pain model. METHODS: Allodynia was induced in male Sprague Dawley rats by the tight ligation of the left lumbar 5th and 6th spinal nerves. We tested the mechanical allodynia by pricking von Frey filaments to the left hind paw and assessed withdrawal thresholds of paw with up-down method. For the estimation of the antiallodynic effect of R-PIA, R-PIA (0.5, 1 and 2microgram) or saline were administered intrathecally.To investigate the reversal effect on antiallodynic effect of R-PIA, variable amounts of 5-hydroxydecanoate (5-HD, 20, 30 and 40 mg), mKATP channel blocker were administered intraperitoneally at 5 min prior to the intrathecal injection of 2microgram of R-PIA, and the degree of allodynia was assessed. RESULTS: The paw withdrawal threshold was gradually increased with increased dose of R-PIA and reached the maximum level with 2microgram R-PIA (P < 0.05). The increase of paw withdrawal threshold with 2microgram R-PIA was significantly reversed dose-dependently by intraperitoneal pretreatment of 20, 30 and 40 mg/kg 5-HD (P < 0.05). CONCLUSIONS: In our results, intraperitoneal injection of 5-HD before intrathecal injection of R-PIA had reversed the antiallodynic effect of R-PIA. This results suggest that the mechanism of mechanical antiallodynia induced by intrathecal injection of R-PIA may relate with the mK(ATP) channel in a rat model of nerve ligation injury.

OBJECTIVES: This study investigated the distribution of causative agents related to occupational lung cancer, their relationships with work, and associations between work-relatedness and the histologic type of lung cancer. METHODS: We used data from the occupational surveillance system in Korea in 2013. In addition, data from 1,404 participants diagnosed with lung cancer were collected through interviews. We included the patients' longest-held job in the analysis. Work-relatedness was categorized as "definite," "probable," "possible," "suspicious," "none," or "undetermined." RESULTS: Among the subjects, 69.3% were men and 30.7% were women. Regarding smoking status, current smokers were the most prevalent (35.5%), followed by non-smokers (32.3%), ex-smokers (32.2%). Regarding the causative agents of lung cancer, asbestos (1.0%) and crystalline silica (0.9%) were the most common in definite work-related cases, while non-arsenical insecticide (2.8%) was the most common in probable cases followed by diesel engine exhaust (1.9%) and asbestos (1.0%). Regarding histologic type, adenocarcinoma was the most common (41.7%), followed by squamous cell carcinoma (21.2%). Among current smokers, squamous cell carcinoma was the most common among definite and probable cases (13.4%), while non-small cell lung cancer was the least common (7.1%). Among non-smokers, squamous cell carcinoma was the most common (21.4%), while the least common was adenocarcinoma (1.6%). CONCLUSIONS: Approximately, 9.5% of all lung cancer cases in Korea are occupational-related lung cancer. Well-known substances associated with lung cancer, such as crystalline silica, asbestos, and diesel engine exhaust, are of particular concern. However, the histologic types of lung cancer related to smoking were inconsistent with previous studies when work-relatedness was taken into account. Future studies are required to clarify the incidence of occupational lung cancer in agricultural workers exposed to non-arsenical insecticides and the associations between work-relatedness and the histologic type of lung cancer.

PURPOSE: This study aimed to propose a common scope of practice (SOP) for 13 specialties of Advanced Practice Nurses (APNs) in Korea.METHODS: The first draft of a common SOP was extracted from domestic and international laws with a literature review by 17 experts from the Korean Association of Advanced Practice Nurses (KAAPN). Then, the common SOP was finalized after comparing the activities of APNs in clinical settings.RESULTS: A total of 70 duties were identified and six categories were suggested for the common SOP. The SOP proposed by the KAAPN featured the following: 1) identification of and discrimination between health problems; 2) prescription and implementation of diagnostic tests; 3) treatment of injuries and diseases while implementing measures to prevent exacerbation; 4) prescription of medicinal products in line with 1) to 3); 5) referral and consultation; and 6) education and counseling. It was then confirmed that the proposed six categories in the common SOP reflected all the duties performed by APNs in clinical practice, including all 40 activities.CONCLUSION: The results of this study can be used as evidence for the legalization of a common SOP for APNs. Given the increasing multidisciplinary team approach adopted in Korean hospitals, it may be desirable to establish a broader SOP to reflect the diverse duties of APNs.

Owing to the development of high resolution-imaging modalities, cavernous angiomas and developmental venous anomalies are no longer uncommon clinical entities. The simultaneous occurrence of cavernous angioma and venous anomaly, however, is rare. In this paper we describe our clinical experience of 13 cavernous angiomas associated with venous anomaly, as well as the clinical and radiological characteristics, and surgical result; We report a retrospective series of cases in our four hospitals between July, 1990 and September, 1996. Seven patients were men and six were women; cavernous angiomas were classified into three pathophysiologic patterns, and venous anomalies were detected by either or a combination of these. In three cases, the MRI, MR angiography, cerebral angiography, venous anomaly was not in the vicinity of the cavernous angioma. Removal of the lesion aimed to eradicate the risk of recurrent bleeding and alleviate the patients' symptoms; no death occured, but patient deteriorated after surgery, showing a postoperative hemiparesis resulting from hemorrhagic venous infarction. In conclusion, the simultaneous occurrence of cavernous angioma and venous malformation is not rare. For the safe removal of a cavernous angioma, preoperative plans should involve considerations of venous anomaly; We believe that for successful surgery, the identification and preservation of venous malformation, which should be left undisturbed during the operation, is essential.
