A complete cDNA sequence encoding a pore-forming subunit (Kir6.2) of ATP-senstive potassium channel in the adult worm, Clonorchis sinensis, termed CsKir6.2, was isolated from an adult cDNA library. The cDNA contained a single open-reading frame of 333 amino acids, which has a structural motif (a GFG-motif) of the putative pore-forming loop of the Kir6.2. Peculiarly, the CsKir6.2 shows a lack-sequence structure, which deleted 57 amino acids were deleted from its N-terminus. The predicted amino acid sequence revealed a highly conserved sequence as other known other Kir6.2 subunits. The mRNA was weekly expressed in the adult worm.

OBJECTIVE: The object of this study was to evaluate the indications, effectiveness and complications associated with arterial embolization as a safe and effective alternative treatment of obstetrical hemorrhage. METHODS: From September 1998 to October 2005, 42 patients who had a pregnancy related hemorrhage which did not respond to treatment using obstetric maneuvers and uterotonic drugs were included in our study. The patients underwent angiographic embolization for the management of intractable obstetrical hemorrhage at Department of Obstetrics and Gynecology, Yonsei University Medical Center. All available medical records and telephone interviews were reviewed and detailed to collect adequate clinical data such as clinical status, underlying conditions, amount of transfusion, embolization sites, materials of embolization, hospital stay, the success rate and the complications. RESULTS: We have experienced clinically successful embolization in 40 (95.2%) of 42 patients of obstetrical hemorrhage resulting from various causes. After embolization, the patient's vital sign was stabilized. The causes of hemorrhage were atony of uterus (n=17), cervical pregnancy (n=5), abnormal placentation (n=5), laceration of uterine cervix and vagina (n=6). The average amount of blood transfusion was 10.3 unit (range; 0-63 unit). The average duration of hospitalization was 7.4 days (range; 4-18 days). We were able to follow up on 32 patients. The main complications after embolization were hypomenorrhea (n=6), numbness of lower extremities (n=3). In all cases menses resumed spontaneously after procedures. CONCLUSION: The arterial embolization is one of the safe and the effective procedures and offers patients a fertility-preserving alternative to hysterectomy for treatment of intractable postpartum hemorrhage.

BACKGROUND: Disability of Activities of daily living (ADL) is the most important factor for care of dementia patients. So Korean Dementia Association has prepared the survey for current state and cognition of active daily living in Korean dementia patients. METHODS: A total of 100 subjects were interviewed. Structured open and closed questions about ADL for dementia were asked. They are main caregivers of dementia patients who working over 5hours per day. Assessments included age, sex, education level, economic status, severity of dementia patients, pattern of the care-giving, current state and cognition of ADL, and needs of the caregivers. RESULTS: The cognition of ADL was very low (51%) and this is correlated with economic status. Increasing of care-giving time is the most stressful for caregivers, they frequently suffered from disability of outgoing and personal hygiene. Dementia patient's ADL disability causes serious economic losses, need of the caregivers about guide lines or education program was very high. CONCLUSION: Considering these results, we should design more detailed study about dementia patient's ADL disability and prepare guide line or program for it.

Systemic lupus erythematosus (SLE) is a chronic inflammatory, heterogeneous autoimmune disease characterized by autoantibody production and the potential involvement of almost every organ system. Although vasculitis usually confined to small vessels is a fairly common feature of SLE, ischemic vasculitis with an aneurysm is an uncommon feature. In particular, renal arterial microaneurysms and multiple renal infarctions are very rarely reported in patients with SLE. Furthermore, to the best of the authors' knowledge, there is no report on renal arterial microaneurysms associated with SLE in Korea. Here, this paper presents a case of renal microaneurysms and multiple renal infarctions in a 41-year-old woman with SLE.

Activities of daily living (ADL) refer to the ability to care for self and perform daily activities within an individual's place or in outdoor environments. ADL comprise two main categories: Basic or physical ADL and Instrumental ADL. The latter allows for the earlier detection of functional decline than the former. The cognitive changes in neurodegenerative dementias contribute to the impaired ability of the patients to take care of themselves. Activities of daily living is a major criterion for diagnosing dementia. Furthermore, it has recently been emphasized that some impairment of activities of daily living, particularly of complex instrumental functions, is already present even in mild cognitive impairment prodromal stage of dementia, although mild cognitive impairment is distinguished from dementia by the absence of significant deficit in activities of daily living. The impaired activities of daily living increase the rate of institutionalization of the patients with dementia to nursing home and inevitably bring about the changes in the qualities of life not only of the patients but their caregivers. One of the best ways to evaluate the degree of impairment in activities of daily living and the care burden is through standardized functional assessment tools according to the severity of dementia. These tools provide objective data, thereby allowing the clinicians to judge decline and improvement in the functional status and to plan individualized care. In this review, we will review the clinical significance of evaluating ADL, the assessment tools according to the severity of dementia, and therapeutic approaches to enhance the functional levels. We will also review the impact of the impaired ADL on the quality of life among the patients and their care providers.

OBJECTIVE: Alcoholic neuropathy is characterized by allodynia (a discomfort evoked by normally innocuous stimuli), hyperalgesia (an exaggerated pain in response to painful stimuli) and spontaneous burning pain. The aim of the present study is to investigate the effect of rolipram, a phosphodiesterase 4 inhibitor, against alcohol-induced neuropathy in rats. METHODS: Allodynia was induced by administering 35% v/v ethanol (10 g/kg; oral gavage) to Spraue-Dawley rats for 8 weeks. Rolipram and saline (vehicle) were administered intraperitoneally. Mechanical allodynia was measured by using von Frey filaments. Somatosensory evoked potential (SEP) was proposed as complementary measure to assess the integrity of nerve pathway. RESULTS: The ethanol-induced mechanical allodynia began to manifest from 3 week, and then peaked within 1 week. Beginning from 3 week, latency significantly started to increased in control group. In rolipram treated rats, the shorter latency was sustained until 8 weeks (p<0.05). The mechanical allodynia, which began to manifest on the 3 weeks, intraperitoneal injections of rolipram sustained statistical difference until 8 weeks, the final week of the study (p<0.05). CONCLUSION: This study suggests that rolipram might alleviate mechanical allodynia induced by alcohol in rats, which clearly has clinical implication.

PURPOSE: The purpose of this study was to determine the significant factors for risk estimate of aspiration and to evaluate the efficiency of the dysphagia assessment tool. METHODS: A consecutive series of 210 stroke patients with aspiration symptoms such as cough and dysphagia who had soft or regular diet without tube feeding were examined. The dysphagia assessment tool for aspiration was compared with videofluoroscopy using Classification and Regression Tree (CART) analysis. RESULTS: In CART analysis, of 34 factors, the significant factors for estimating risk of aspiration were cough during swallowing, oral stasis, facial symmetry, salivary drooling, and cough after swallowing. The risk estimate error of the revised dysphagia assessment tool was 25.2%, equal to that of videofluoroscopy. CONCLUSION: The results indicate that the dysphagia assessment tool developed and examined in this study was potentially useful in the clinical field and the primary risk estimating factor was cough during swallowing. Oral stasis, facial symmetry, salivary drooling, cough after swallowing were other significant factors, and based on these results, the dysphagia assessment tool for aspiration was revised and complemented.
