고영록,노준,소영석 朝鮮大學校 附設 醫學硏究所 2003 The Medical Journal of Chosun University Vol.28 No.2
Objectives: To compare the efficacy of the Dornier Compact Delta lithotriptor with the Northgate SD-3 lithotriptor in the treatment of upper and mid-ureteral stones. Materials and Methods: A total of 243 patients without any previous experience of ESWL were treated for upper and mid-ureteral stones. 121 patients were managed with the Northgate SD-3 lithotriptor which had ultrasonography targeting system and electro hydraulic shock wave source. The other 122 patients were treated with the Dornier Compact Delta equipped with a fluoroscopic focusing system and electromagnetic shock wave source. The locations and sizes of stones, sessions, stone-free rates, auxiliary procedures, and complications of ESWL were reviewed retrospectively. In each group stone-free results were determined by KUB 1 month after the last ESWL and then efficacy quotients (EQ) were obtained. Results: Baseline characteristics were equivalent, including patient ages, sex ratio, stone numbers and locations. Using the Northgate SD-3 lithotriptor, the average sessions and stone-free rates were 1.53 and 86.8%, respectively. Using the Dornier Compact Delta lithotriptor, average sessions and stone-free rate were 1.38 and 92.6 %, respectively. Effectiveness quotient(EQ) in the Northgate SD-3 and the Dornier Compact Delta was 61 and 65, the rates of the auxiliary procedure were 9.1% and 18%. Conclusions: The Dornier Compact Delta lithotripsy resulted in a higher stone-free rate and EQ, although it was associated with a higher rate of pre-ESWL auxiliary procedures than the Northgate SD-3 Lithotripsy.

<P><B>Purpose</B></P><P>Aging-induced loss of muscle mass and subsequent reduction of strength is a fundamental cause of frailty, functional decline, and disability. And this may lead to muscular dysfunction, voiding dysfunction, or urinary incontinence due to pelvic muscle weakness induced by aging. Physical exercise has been recommended for the prevention and the treatment of these age-related frail states. We investigated the effects of treadmill exercise on muscle strength, myostatin mRNA and protein expression, and gastrocnemius myocytes proliferation in aged rats to investigate the possible antiaging effects of aerobic exercise on skeletal muscles such as pelvic floor muscles and urethral rhabdosphincter muscle.</P><P><B>Methods</B></P><P>In this study, 5-month-old male Sprague-Dawley rats were used as the young-age group (n=20) and 24-month-old rats were used as the old-age group (n=20). Each group was randomly divided into two groups (n=10 in each group): the sedentary and the treadmill exercise group. The rats in the exercise groups were forced to run on a motorized treadmill for 30 minutes, once a day, for 6 weeks. For this study, a weight load test, hematoxylin and eosin staining, real-time and reverse transcription polymerase chain reaction for myostatin mRNA, myostatin western blot, and 5-bromo-2'-deoxyuridine immunohistochemistry were performed in the gastrocnemius muscle.</P><P><B>Results</B></P><P>The age-induced reduction of muscle mass and strength was associated with a decrease in myocyte proliferation and an increase in myostatin mRNA and protein expression in the gastrocnemius. However, treadmill exercise improved muscle mass and strength through suppression of myostatin mRNA and protein expression, and myocyte proliferation increase in the gastrocnemius against the aging process.</P><P><B>Conclusions</B></P><P>Aerobic exercise is a useful strategy for enhancing muscle function against aging-induced loss of skeletal muscle mass and functions.</P>

In order to know the residual pattern of pesticides and predict to the degradation period until below MRL, we experimented diazinon, iprodinon and chlorfenapyr for shallot. They were the most detected pesticide in shallot by NAQS (National Agricultural product Quality management Service) survey. In this experiment, we sprayed those pesticides 15days before harvest and analyzed 0, 1, 2, 3, 5, 7, 10, 14 day sample to establish logical equation and to calculate DT_(50). During the cultivating period, the residue amount of diazinon was changed from 1.02 mg/kg (0 day) to 0.01 mg/kg (14 day), DT_(50) was 2.19 days, and iprodione was changed from 1.45 mg/kg (0 day) to 0.14 mg/kg (14 day), DT_(50) was 4.15 days, and chlorfenapyr was changed from 1.5 mg/kg (0 day) to 0.01 mg/kg (14 day), DT_(50) was 1.97 days. The DT_(50) of double amount in those pesticides, diazinon was 2.24 days, iprodione was 4.82 days, and chlorfenapyr was 2.24 days, respectively.

연구목적: 우리나라의 결핵약제에 대한 내성은 지속적으로 감소되고 있음에도 불구하고 여전히 적지 않은 환자를 보유하고 있는 상황에서 치료 실패의 중요한 요인이 되고 있다. 이에 결핵 내성률에 영향을 미칠 수 있는 인자들을 파악하고 이에 대한 예방 대책을 수립하는 것이 내성률 발생의 예방에 도움이 될 것으로 사료된다. 이에 저자들은 광주 소재의 한 2차 병원에서 결핵 약제 내성률 및 위험인자로 판단되는 요소들과의 상호관계를 조사하였다. 대상 및 방법: 2005년 3월 부터 2006년 2월 까지 광주 기독 병원 내과에서 치료받은 결핵 환자중 객담 결핵균 배양 검사상 양성으로 판명되어 약제 감수성 검사를 확인할 수 있었던 346명을 대상으로 의무기록, 면담 등을 통한 후향적 조사를 시행 하였다 결과: 346명중 한가지 이상의 약제에 내성을 보인 경우는 150명(43.4%)였고, 다제 내성 결핵은 72명(20.8%)였다. 조사 요인의 유무별로 약제 내성률을 조사하였을 때 흉부 사진의 침범 정도에 따른 약제 내성률 및 다제 내성률은 경증에서 36.3%와 6.2%, 중등도에서 36.1%와 22.6%, 중증에서 61.0%와 35.0%였다. 병변의 공동성 병변 유무에 따른 약제 내성률은 공동이 있는 군에서는 49.8%, 공동이 없는 군에서는 34.0%였다. 과거의 치료력 여부에 따른 약 제 내성률은 치료력이 없는 군에서는 19.7%였고, 치료력이 있는 군에서는 81.2%였다. 항 결핵제 복용의 규칙성 여부에 따른 약제 내성률은 규칙적 복용군은 31.7%, 불규칙적 복용군은 59.7%로 나타났다. 결론: 광주 소재의 한 2차 병원에서 조사한 약제 내성률 및 다제 내성률은 전국 평균치를 훨씬 상회하였다. 한편 과거 치료병력 및 약제의 불규칙 복용은 약제 내성률을 높이는 데에 기여하는 인자가 될 것으로 사료된다. 흉부방사선 사진 상의 폐 침범 정도, 공동성 병변의 존재도 약제 내성률 증가와 관련이 있는 것으로 보이나 보다 정확한 선후관계 분석을 위해서는 추가적인 전향적 연구가 필요하다. Background and objectives: Drug resistance is a major obstacle to the treatment of pulmonary tuberculosis (TB). This study was conducted to determine the prevalence of drug-resistant tuberculosis and its associated factors at a secondary hospital in Gwangju. Materials and Methods: A retrospective one-center analysis was conducted, with 346 pulmonarytuberculosis patients who underwent drug susceptibility tests for M. tuberculosis at Gwangju Christian Hospital from March 2005 to February 2006. Results: The following percentages of subjects were found to be resistant to at least one drug and to have multidrug-resistant tuberculosis (MDR-TB), respectively: 43.4% and 20.8% of all the subjects; according to the severity of the chest X-ray findings, 36.3% and 6.2% in the mild group, 36.1% and 22.6% in the moderate group, and 61.0% and 35.0% in the far- advanced group; according to the presence of a cavitary lesion, 49.8% in the cavitary-lesion group and 34.0% in the noncavitary-lesion group and according to the history of previous tuberculosis treatment, 81.2% in the group who have had treatment and 19.7% in the group who have never had treatment. The resistance rate according to the regularity of antituberculosis drug medication was 31.7% in the regular medication group and 59.7% in the irregular medication group. Conclusion: The drug resistance rate was increased by the history of previous tuberculosis treatment and the irregular medication. As to whether the severity of chest X-ray findings and the presence of cavitary lesions have a correlation with drug resistance, prospective studies are needed for more accurate results.
