Purpose: This study researched the comparison of oral care methods between the wet gauze and the water gargling for nasal surgery patients. It executed to find out more effective method to relieve thirst. Method: We divided two groups; the wet gauze and the cold water garaling. We assessed patient's oral cavity state and sebjective oral dryness for three times; firstly before the intervention, secondly 15 minutes after 1st intervention and thirdly 15 minutes afrer 2nd intervention. Result: As the intervention, there was no difference on oral condition subhectvely, but there was a difference on thirsty reduction objectively. As the aral dryness has relieved through both methods. It showed the repeated gargling helps more to relieve oral dryness effectively than the wet gauge. At PACU, post nasal surgery patient's oral dryness was decreased with gauze more than two times, patient's oral dryness was relieved. Whereas the dryness was relieved after applying the cold water gargling for just one time. Conclusion: The water gargling is more effective intervention than the wet gauze. Especially, oral dryness was improved in the section of objetive oral assessment index.

2, 4, 6-Collidinium dichromate(CDC) is more, stable. nonhygroscopic, and milder than other chromium(VI)oxidants. The new oxidant was characterized via rate of oxidation. CDC with pyridinium P-toluenesulfonate(PPTS) in dichloromethane was effective in oxidation of allylic, benzylic, and secondary alcohols to the corresponding carbonyl compounds at room temperature. while CDC alone did not oxidize above alcohols. Oxidation of ally lie and benzylic alcohols progressed more repididly than that of secondary alcohols. When molecular sieve(MS)was added to the CDC-PPTS system, rate of oxidation and yields increased. Saturated aliphatic primary alcohols were decomposed in two system, CDC-PPTS and CDC-PPTS system added MS. The oxidation selectivity of CDC-PPTS system was increased about 1.75 times than that of PDC-PPTS system.

Aplastic anemia is a disease characterized by pancytopenia in the peripheral blood and hypocellular bone marrow with the fatty infiltration. The causes of the acquired aplastic anemia were usually related to drugs and immune-related diseases. A 34-years old man was admitted due to general weakness. He has been going hemodialysis for 2 years because of end stage renal disease (ESRD) due to chronic glomerulonephritis. At admission, laboratory tests showed hemoglobin 6.2 g/dL, hematocrit 18.0 %, WBC 5,710mm (neutrophil 71.8%, lymphocyte 19.1%, monocyte 5.9%), reticulocyte 1.9%, platelet 93,000/mm, Fe 12.8 ug/dL, TIBC 204 ug/dL, ferritin 941.47 ng /ml, haptoglobin 0.72 g/L, vitamin B12 508.17 pmol/L, folate 24 ng/mL, total protein 6.54 g/dL, albumin 3.76 g/dL, Alk. pohsphatase 79 IU/L, AST 30.0 IU/L, ALT 39.7 IU/L, total bilirubin 0.57 mg/dl, BUN 79.4 mg/dl and creatinine 10.18 mg/dl. Peripheral blood smear showed the normocytic normochromic anemia with anisocytosis. Anemia was diagnosed but it was irresponsive to the recombinant human erythropoietin (EPO) and blood transfusion. In the bone marrow aspiration smear were there the hypoplastic myeloid and erythroid precursors. The bone marrow biopsy section showed the hypoplasia of all components (10-20%) and the fatty infiltration. We have experienced one case of the idiopathic aplastic anemia in a patient going through hemodialysis and we just report it with documentary records. 저자들은 혈액 투석 중인 환자에서 약물, 면역계 이상등의 원인을 발견할 수 없었음에도 재생 불량성 빈혈이 발생한 1예를 경험하여 문헌 고찰과 함께 보고하는 바이다.

( Hyun Hee Lee ),( Soo Jung Choi ),( Heon Nam Lee ),( Sun Young Na ),( Jae Hyun Chang ),( Woo Kyung Chung ),( Se Joong Kim ) 대한신장학회 2010 Kidney Research and Clinical Practice Vol.29 No.1

Purpose: Hyponatremia occurs infrequently in patients undergoing peritoneal dialysis (PD). Nevertheless, one must understand its pathophysiology, since the therapeutic strategy differs from that of non-PD-related hyponatremia. This study examined the clinical features of hyponatremia in PD and evaluated the factors that may contribute to its development. Methods: We retrospectively enrolled 51 normonatremic PD patients at Gachon University Gil Hospital, South Korea. Using the plasma sodium levels at month 13, the patients were divided into hyponatremia (Na+<135mEq/L) and normonatremia (Na+≥135mEq/L) groups. Then, the clinical variables of these patients were examined, including peritoneal function and adequacy tests, and biochemical parameters. Results: The de novo hyponatremia (n=8) and normonatremia (n=43) groups had no significant differences in baseline characteristics. At month 1, the serum albumin was lower in the hyponatremia group (p=0.022). In the peritoneal equilibration test analysis, the dialysate-to-plasma ratio for creatinine (D/Pcr) measured after 13 months differed significantly between the two groups (p=0.007), while the maximum dip in sodium did not differ. No significant differences were observed in the normalized protein equivalent of nitrogen appearance, Kt/V, or residual renal function. Conclusion: Our data suggest that the development of hyponatremia is associated with a lower initial serum albumin level and increased D/Pcr in patients undergoing PD. Therefore, the serum sodium levels should be monitored more carefully in these patients.

Background and Purposes: Over the past three decades, numerous studies performed in Korea have reported that job stress is a determinant risk factor for chronic diseases and work disability. Every society has its own culture and occupational climate particular to their organizations, and hence experiences different occupational stress. An occupational stress measurement tool therefore needs to be developed to estimate it objectively. The purpose of this study is to develop and standardize the Korean Occupational Stress Scale (KOSS) which is considered to be unique and specific occupational stressors in Korean employees. Subjects and Methods: Data were obtained from the National Study for Development and Standardization of Occupational Stress (NSDSOS Project: 2002-2004). A total of 12,631 employees from a nationwide sample proportional to the Korean Standard Industrial Classification and the Korean Standard Occupational Classification were administered. The KOSS was developed for 2 years (2002-2004). In the first year, we collected 255 items from the most popular job stress measurement tools such as JCQ, ERI, NIOSH and OSI, and 44 items derived from the a qualitative study (depth interview). Forty-three items of KOSS, in the second year, were retained for use in the final version of the KOSS by using Delphi and factor analysis. Items were scored using conventional 1-2-3-4 Likert scores for the response categories. Results: We developed eight subscales by using factor analysis and validation process: physical environment (3 items), job demand (8 items), insufficient job control (5 items), interpersonal conflict (4 items), job insecurity (6 items), organizational system (7 items), lack of reward (6 items), and occupational climate (4 items). Together they explained 50.0% of total variance. Internal consistency alpha scores were ranged from 0.51 to 0.82. Twenty-four items of the short form of the KOSS (KOSS-SF) were also developed to estimate job stress in the work setting. Because the levels of the subscales of occupational stress were gender dependent, gender-specific standard norms for both the 43-item full version and the 24-item short form using a quartile for the subscales of KOSS were presented. Conclusion: The results of this study suggest that KOSS might be an appropriate measurement scale to estimate occupational stress of Korean employees. Further and more detailed study needs to be conducted to improve the validity of this scale.
