Clonorchis sinensis habitating in the bile duct of mammals causes clonorchiasis endemic in East Asian countries. Parkin is a RING-between-RING protein and has E3-ubiquitin ligase activity catalyzing ubiquitination and degradation of substrate proteins. A cDNA clone of C. sinensis was predicted to encode a polypeptide homologous to parkin (CsParkin) including 5 domains (Ubl, RING0, RING1, IBR, and RING2). The cysteine and histidine residues binding to Zn2+ were all conserved and participated in formation of tertiary structural RINGs. Conserved residues were also an E2-binding site in RING1 domain and a catalytic cysteine residue in the RING2 domain. Native CsParkin was determined to have an estimated molecular weight of 45.7 kDa from C. sinensis adults by immunoblotting. CsParkin revealed E3-ubiquitin ligase activity and higher expression in metacercariae than in adults. CsParkin was localized in the locomotive and male reproductive organs of C. sinensis adults, and extensively in metacercariae. Parkin has been found to participate in regulating mitochondrial function and energy metabolism in mammalian cells. From these results, it is suggested that CsParkin play roles in energy metabolism of the locomotive organs, and possibly in protein metabolism of the reproductive organs of C. sinensis.

OBJECTIVE: To investigate the frequency, type and severity of cardiac abnormalities in the patients with ankylosing spondylitis and undifferentiated spondyloarthopathy. METHODS: A history, clinical examination, standard 12 lead electrocardiography, two dimensional, M mode, and Doppler echocardiographies were performed on 19 patients with ankylosing spondylitis, 15 patients with undifferentiated spondyloarthropathy and 21 normal controls. RESULTS: 1) Cardiac abnormalities were detected in 8 patients(42.1%) with ankylosing spondylitis. 2) Cardiac abnormalities were detected in 8 patients(53.3%) with undifferentiated spondyloarthropathy including 2 patients with aortic valve abnormalities(mild aortic insufficiency, aortic valve thickening. 3) Cardiac abnormalities were detected in one (4. 8%) among normal controls (mild tricuspid regurgitation). 4) There were sinus bradycardias on electrocardiography in 2 patients among patients witn anl;ylosing spond!litis and in 1 patient among undifferentiated spondyloarthropathy. But there was no conduction disturbance in both groups. 5) The frequency of cardiac abnormality was higher in patients with ankylosing spondylitis and undifferentiated spondyloarthropathy than in normal controls. 6) The mean age, mean disease duration, presence of uveitis, peripheral arthritis, HLA-B27, enthesopathy, Schober test and chest expansion in the patients with ankylosing spondylitis and undifferentiated spondyloarthropathy with cardiac abnormalities were not different from those in the patients without cardiac abnormalities. CONCLUSION: The frequency of cardiac abnormality was higher in patients with ankylosing spondylitis and undifferentiated spondyloarthropathy than in normal controls. The frequency, type and severity of cardiac involvement in patients with ankylosing spondylitis were not different from those in patients with undifferentiated spondyloarthropathy.

Objective:
: This study aimed to validate the Korean version of the Repeatable Battery for the Assessment of Neuropsychological Status Update (K-RBANS).
Methods:
: We performed a retrospective analysis of 283 psychiatric and neurosurgery patients. To investigate the convergent validity of the K-RBANS, correlation analyses were performed for other intelligence and neuropsychological test results. Confirmatory factor analysis was used to test a series of alternative plausible models of the K-RBANS. To analyze the various capabilities of the K-RBANS, we compared the area under the receiver operating characteristic (ROC) curves (AUC).
Results:
: Significant correlations were observed, confirming the convergent validity of the K-RBANS among the Total Scale Index (TSI) and indices of the K-RBANS and indices of intelligence (r=0.47–0.81; p<0.001) and other neuropsychological tests at moderate and above significance (r=0.41–0.63; p<0.001). Additionally, the results testing the construct validity of the K-RBANS showed that the second-order factor structure model (model 2, similar to an original factor structure of RBANS), which includes a first-order factor comprising five index scores (immediate memory, visuospatial capacity, language, attention, delayed memory) and one higher-order factor (TSI), was statistically acceptable. The comparative fit index (CFI) (CFI, 0.949) values and the goodness of fit index (GFI) (GFI, 0.942) values higher than 0.90 indicated an excellent fit. The root mean squared error of approximation (RMSEA) (RMSEA, 0.082) was considered an acceptable fit. Additionally, the factor structure of model 2 was found to be better and more valid than the other model in χ2 values (Δχ2=7.69, p<0.05). In the ROC analysis, the AUCs of the TSI and five indices were 0.716–0.837, and the AUC of TSI (AUC, 0.837; 95% confidence interval, 0.760–0.896) was higher than the AUCs of the other indices. The sensitivity and specificity of TSI were 77.66% and 78.12%, respectively.
Conclusion
: The overall results of this study suggest that the K-RBANS may be used as a valid tool for the brief screening of neuropsychological patients in Korea.

OBJECTIVE: To introduce a newly designed arm sling and to compare the effects on a shoulder subluxation. METHOD: Sixteen hemiplegic patients with shoulder subluxation were evaluated by a simple X-ray with and without the slings and the vertical and horizontal distances on the plain AP views were measured. The newly designed arm sling was compared in terms of the effects of correction with a pouch sling and a Bobath sling. The arm sling designed for this study was developed for the purpose of maintaining patients' hands in a functional position and performing ROM exercise of the shoulder easily. The mean values of the vertical and horizontal distance were compared to determine if there was significant difference of function between the new sling and the conventional slings. Variables such as comfort, choice, and easiness for donning and doffing of the arm slings were evaluated by questions. RESULTS: The new sling provided the patients with good vertical correction of the subluxation (p<0.05) but did not increase the horizontal distance significantly. According to the responses to the questions, the new sling was more comfortable than the conventional slings. CONCLUSION: These results support the effectiveness and the comfort of a new sling to decrease subluxation in hemiplegia. Further study on the long term effects or complication of the new sling is recommended.

Hypoxia-ischemia leads to serious neuronal damage in some brain regions and is a strong risk factor for stroke. The aim of this study was to investigate the neuroprotective effect of tanshinone I (TsI) derived from Danshen (Radix Salvia miltiorrhiza root extract) against neuronal damage using a mouse model of cerebral hypoxia-ischemia. Brain infarction and neuronal damage were examined using 2,3,5-triphenyltetrazolium chloride (TTC) staining, hematoxylin and eosin histochemistry, and Fluoro-Jade B histofluorescence. Pre-treatment with TsI (10 mg/kg) was associated with a significant reduction in infarct volume 1 day after hypoxia-ischemia was induced. In addition, TsI protected against hypoxia-ischemia-induced neuronal death in the ipsilateral region. Our present findings suggest that TsI has strong potential for neuroprotection against hypoxic-ischemic damage. These results may be used in research into new anti-stroke medications.

Clonorchis sinensis is a carcinogenic human liver fluke that promotes hepatic inflammatory environments via direct contact or through their excretory-secretory products (ESPs), subsequently leading to cholangitis, periductal fibrosis, liver cirrhosis, and even cholangiocarcinoma (CCA). This study was conducted to examine the host inflammatory responses to C. sinensis ESPs and their putative protein components selected from C. sinensis expressed sequenced tag (EST) pool databases, including TGF-β receptor interacting protein 1(CsTRIP1), legumain (CsLeg), and growth factor binding protein 2 (CsGrb2). Treatment of CCA cells (HuCCT1) with the ESPs or bacterial recombinant C. sinensis proteins differentially promoted the secretion of proinflammatory cytokines (IL-1β, IL-6, and TNF-α) as well as anti-inflammatory cytokines (IL-10, TGF-β1, and TGF-β2) in a time-dependent manner. In particular, recombinant C. sinensis protein treatment resulted in increase (at maximum) of ~7-fold in TGF-β1, ~30-fold in TGF-β2, and ~3-fold in TNF-α compared with the increase produced by ESPs, indicating that CsTrip1, CsLeg, and CsGrb2 function as strong inducers for secretion of these cytokines in host cells. These results suggest that C. sinensis ESPs contribute to the immunopathological response in host cells, leading to clonorchiasis-associated hepatobiliary abnormalities of greater severity.

BACKGROUND: Spirituality has been an important part of Transpersonal Psychology and is believed to have a large effect on the mental health because it has been systematized. The aim of this study was to determine the level of spiritual disposition on human beings along with its effects on one's mental health. MATERIALS AND METHODS: The study targeted 400 women residing in Youn-Gil city of JiLin Prov., which is a district of the Cho-Sun tribe in China. Their spiritual well-being was studied using the Spiritual Well-being Scale-Korean Version. The spiritual well-being scale consists of 2 sub-scales of religious well-being and existential well-being. The study was evaluated using a lie scale, psychotic trend, and a combined anxiety-depression scale. The results were considered to be factors of one's mental health. The correlation between the spiritual well-being and each tendency was analyzed by regression analysis. RESULTS: The total score of the Cho-Sun tribal women according to the spiritual well-being scale was 68.29 which was much less than the 100.65 of Korean Christian women. There was no significant correlation between the spiritual well-being and the Lie trend. However, it was found that 86% (344) of Cho-Sun tribal women scored above 70 in the Lie trend with a mean score of 74.57 which is higher than normal populations. Regarding the correlation between the spiritual well-being and psychotic trend, the psychotic trend became significantly higher when the religious well-being was at a high level. On the other hand, the psychotic trend became significantly lower when the existential well-being was at a high level. Regarding the correlation between the spiritual well-being and anxiety, the anxiety was significantly higher when the religious well-being was at a high level. However, the anxiety level was significantly low when the existential well-being was at a high level. Regarding the correlation between the spiritual well-being and depression, the depression level was somewhat significantly high when the religious well-being was at a high level. However, the depression level was significantly low when the existential well-being was at a high level. CONCLUSION: This study evaluated the effects of spiritual well-being on a person's mental health among Cho-Sun tribal women in Youn-Gil city of JiLIn Prov., P.R. of China. The results found that the religious well-being, which is a sub-scale of spiritual well-being, had negative effects while the existential well-being had positive effects on the mental health. These results proved that a person's religious disposition had negative effects on their mental health in a communitarian society.

BACKGROUNDWater dropwort (Oenanthe javanica) as a popular traditional medicine in Asia shows various biological properties including antioxidant activity. In this study, we firstly examined the neuroprotective effect of Oenanthe javanica extract (OJE) in the hippocampal cornus ammonis 1 region (CA1 region) of the gerbil subjected to transient cerebral ischemia.
METHODSGerbils were established by the occlusion of common carotid arteries for 5 min. The neuroprotective effect of OJE was estimated by cresyl violet staining. In addition, 4 antioxidants (copper, zinc superoxide dismutase [SOD], manganese SOD, catalase, and glutathione peroxidase) immunoreactivities were investigated by immunohistochemistry.
RESULTSPyramidal neurons in the CA1 region showed neuronal death at 5 days postischemia; at this point in time, all antioxidants immunoreactivities disappeared in CA1 pyramidal neurons and showed in many nonpyramidal cells. Treatment with 200 mg/kg, not 100 mg/kg, OJE protected CA1 pyramidal neurons from ischemic damage. In addition, 200 mg/kg OJE treatment increased or maintained antioxidants immunoreactivities. Especially, among the antioxidants, glutathione peroxidase immunoreactivity was effectively increased in the CA1 pyramidal neurons of the OJE-treated sham-operated and ischemia-operated groups.
CONCLUSIONOur present results indicate that treatment with OJE can protect neurons from transient ischemic damage and that the neuroprotective effect may be closely associated with increased or maintained intracellular antioxidant enzymes by OJE.

The genus Populus (poplar) belonging to the Salicaceae family has been used in traditional medicine, and its several species show various pharmacological properties including antioxidant and anti-inflammatory effects. No study regarding protective effects of Populus species against cerebral ischemia has been reported. Therefore, in the present study, we examined neuroprotective effects of ethanol extract from Populus tomentiglandulosa (Korea poplar) in the hippocampal cornu ammonis (CA1) area of gerbils subjected to 5 minutes of transient global cerebral ischemia. Pretreatment with 200 mg/kg of P. tomentiglandulosa extract effectively protected CA1 pyramidal neurons from transient global cerebral ischemia. In addition, glial fibrillary acidic protein immunoreactive astrocytes and ionized calcium binding adapter molecule 1 immunoreactive microglia were significantly diminished in the ischemic CA1 area by pretreatment with 200 mg/kg of P. tomentiglandulosa extract. Briefly, our results indicate that pretreatment with P. tomentiglandulosa extract protects neurons from transient cerebral ischemic injury and diminish cerebral ischemia-induced reactive gliosis in ischemic CA1 area. Based on these results, we suggest that P. tomentiglandulosa can be used as a potential candidate for prevention of ischemic injury.
