Purpose: The purpose of this quasi-experimental research is to develop the CP for primary THR patients and verify its effectiveness. Method: The CP is designed for both patients and medical employees to meet the 14-day-long hospitalization with an expert and clinical validity test, and the standardized orders are also created. 21 eligible subjects for the control group(with common care plan) and 27 subjects for the experimental group(with CP service) were assigned. Data were collected from questionnaires to evaluate patients' satisfaction level of nursing care and CP, investigation of physical complications, inspection of LOS(length of hospital stay) and hospital charges from April 2000 to February 2001 at K-hospital in Daegu. The collected data were analyzed by using the SAS program. Results: After implementation of CP, there was a statistically significant reduction in mean length of stay. The hospital charges have no considerable difference between two groups. Frequency of physical complications is reduced considerably. The experimental group scored much higher than the control group on the satisfaction level toward nursing care. And in the analysis of CP satisfaction questionnaires, many subjects have high satisfaction in items of 'I see the treatment process and hospital life', 'I feel that I am participating in my treatment process with health care staff'. The analysis of variances which cause a prolonged LOS supports that it's necessary to strengthen an evaluation of pre-operative outpatients' condition and link the home nursing care system in discharge for more shortening of LOS. Conclusion: The above results show that CP can have a positive impact on satisfaction level of inpatients with primary THR and the hospital.

The total hip replacement (THR) has been used as the most effective way to restore the function of damaged hip joint. However, various factors have caused some side effects after the THR. Unfortunately, the success of the THR have been decided only by the proficiency of surgeons so far. Hence, It is necessary to find the way to minimize the side effect caused by those factors. The purpose of this study was to suggest the definite data, which can be used to design and choose the optimal hip implant. Using finite element analysis (FEA), the biomechanical condition of bone cement was evaluated. Stress patterns were analyzed in three conditions: cement mantle, procimal femur and stem-cement contact surface. Additionally, micro-motion was analyzed in the stem-cement contact surface. The 3-D femur model was reconstructed from 2-D computerized tomography (CT) images. Raw CT images were preprocessed by image processing technique (i.e. edge detection). In this study, automated edge detection system was created by MATLAB coding for effective and rapid image processing. The 3-D femur model was reconstructed based on anatomical parameters. The stem shape was designed using that parameters. The analysis of the finite element models was performed with the variation of parameters. The biomechanical influence of each parameter was analyzed and derived optimal parameters. Moreover, the results of FE A using commercial stem model (Zimmer's V erSys) were similar to the results of stem model that was used in this study. Through the study, the improved designs and optimal factors for clinical application were suggested. We expect that the results can suggest solutions to minimize various side effects.

Objective: To investigate any association between XRCC1 and XRCC3 polymorphisms and outcome of platinum-based chemotherapy in ovarian cancer patients. Methods: With a prospective study design was cases were consecutively collected from January 2005 to January 2007. All 310 included patients were followed-up until the end of January 2010. Genotyping of XRCC1 and XRCC3 polymorphisms was conducted by TaqMan Gene Expression assays. Results: A total of 191 patients died during follow-up. Our study showed a lower survival rate in XRCC1 399 Arg/Arg genotype than Gln/Gln, with a significant increased risk of death (HR=1.69, 95%CI=1.07-2.78). Similarly, those carrying XRCC3 Thr/Thr genotype had a increased risk as compare to the Met/Met genotype, with a HR (95% CI) of 1.90 (1.12-3.41). There was no significant association between XRCC1 Arg194Trp and XRCC1Arg280His gene polymorphisms and ovarian cancer death. Conclusion: Our study demonstrates that polymorphisms in DNA repair genes have roles in the susceptibility and survival of ovarian cancer patients.

본 연구에서는 인뇨에서 분리 정제한 urokinase와 유전자 재조합 CHO(Chinese Hamster Ovary) 세포 배양액으로부터 분리 정제한 pro-urokinase의 물리화학적 특성과 혈액 내에서의 효소활성을 비교 분석하였다. Two chain form인 urokinase와 single chain form인 pro-urokinase를 각각 순수 분리한 후, electrophoresis한 결과 모두 54 kd의 단일밴드를 나타냈다. 그러나 urokinase는 환원시켰을 때 33 kd과 21 kd으로 나누어짐을 확인하였으나 gel filtration결과 분자량이 54 kd 정도임을 확인되어 용액 내에서 단일분자로 존재함을 알 수 있었다. Urokinase와 pro-urokinase가 물리화학적으로 거의 동일한 구조를 가졌다는 사실은 isoelectro focusing에 의한 pI 값이 모두 8.6으로 동일하다는 점과, 아미노산 조성을 분석한 결과 동일하다는 사실로도 알 수 있었다. N-terminal 아미노산 서열을 분석한 결과, urokinase는 이중사슬구조이므로 N-terminal이 두개 존재하여 pro-urokinase의 서열(Ser-Asn-Glu-Leu-His-Gln-Val-Pro-Ser-Asn)이외에도, 159번째의 Ile다음부터 Ile-Gly-Gly-Glu-Phe-Thr-Thr-Ile-Glu가 같은 peak로 나타남을 확인하였다. 효소활성 조사결과 pro-urokinase와 urokinase는 모두 농도 의존적으로 혈전용해 활성을 보였으나, 특이하게도 짧은 반응시간동안에는 urokinase가 동일 농도 하에서 강한 활성을 보인 반면, 2시간이 지난 오랜 반응조건에서는 pro-urokinase가 혈전용해활성을 나타내었다. Fibrinogen에 대한 분해활성을 조사한 결과, urokinase는 혈장 내 fibrinogen을 상당히 손상시키지만, pro-urokinase는 거의 영향을 주지 않아 혈전선택성이 매우 좋음을 알 수 있었다.

A Maltese (case 1) and a Pomeranian (case 2) presented with acute right and left hind limb weight-bearing lameness. On physical examination, they exhibited severe pain and crepitus on the coxofemoral joint of affected hind limb. In addition, decreased thigh girth measurements were noted compared with the opposite leg. Radiological exam revealed necrotic areas in the femoral head of affected hind limb. These dogs were diagnosed with Legg-$Calv{\acute{e}}$-Perthes disease (LCPD). The dogs underwent micro total hip replacement (THR). After surgery, at 3 years (case 1) and 7 months (case 2), both dogs recovered normal activity. The thigh girth and lameness scores were apparently improved in the affected limbs of both dogs. No complications of prosthesis implants, such as loosening, were noted. The clinical outcomes of these cases indicate that dogs with LCPD can be successfully treated with micro THR and have a good prognosis immediately after surgery.
