Background: One of the major side effects of cancer chemotherapy is myelosuppression. Neutropenia and/or thrombocytopenia are dose-limiting factors in chemotherapy. Colony-stimulating factor induces proliferation and functional maturation of hematopoietic progenitor cells. GM-CSF is primarily active on progenitor cells of granulocytic and monocytic lineage. Methods: Fifteen patients with histologically proven malignancy diagnosed at Chungnam National University Hospital from January 1993 to August 1995 were included in this study. We could evaluate the clinical efficacy of GM-CSF in 13 patients undergoing FCL(5-FU, Carboplatin and Leucovorin) chemotherapy; the first cycles involved no GM-CSF while the second cycles involved GM-CSF on day 6 through 15 of chemotherapy. Results: 1) The subjects were fifteen patients in all, there were five patients with head and neck cancer, which was the most common types of maligancy. There were four patients with colon cancer, two patients with stomach cancer, and one patient with breast cancer, gallbladder cancer, cervix cancer and cholangiocarcinoma respectively, two patients, who did not complete two cycles of chemotherapy were excluded. 2) Age distribution was from 38 years to 78 years with a median age of 57. 3) In FCL chemotherapy cycles with GM-CSF, the duration of neutropenia(<500/μL) was 0.5±0.3 day, while FCL chemotherapy cycles without GM-CSF, it was 2.9±0.7 day(P=0.008). 3) There was no significant difference in platelet count between the two chemotherapy cycles(P=0.133). 4) Febrile duration without GM-CSF was 4.9±2.1 day, but with GM-CSF the duration was 1.3±0.7 day, which was significantly different(P=0.003). The duration of antibiotics use with GM-CSF was 1.7±1.2 day and without GM-CSF was 6.8±3.2 day, also significantly different(P=0.002). But hospital stay between the two cycles were not significantly different(P=0.064). Conclusion: GM-CSF was effective in preventing or restoring bone marrow depression after FCL chemotherapy.

목적 : 경피적 관동맥 중재술은 최근 양적 및 질적으로 급격한 발전을 보였지만 시술 시 천자부위의 혈관 합병증은 아직 해결해야 할 문제점이다. 저자들은 대퇴동맥을 통한 경피적 관동맥 중재술을 환자에게 천자부위 지혈을 위한 혈관폐쇄기구인 안지오실의 안전성과 유용성을 고식적인 용수 압박법과 비교 연구하고자 하였다. 방법 : 2002년 4월부터 2003년 5월 사이에 삼성서울병원 심장혈관센터에서 대퇴동맥을 통한 경피적 관동맥 중재술을 성공적으로 시행한 200명의 환자(안지오실 사용군: A군, 100명, 고식적 용수압박법 사용군 B군, 100명)를 대상으로 시술 후 주요 합병증 및 경한 합병증, 지혈 후 환자가 자리에 앉기까지의 시간, 보행개시 가능시간, 총 재원 기간과 시술 1주 후의 합병증을 전향적으로 조사하여 비교 연구하였다. 결론 : 두 군에서 연령, 성별, 기저질환, 심혈관 질환의 위험요소, 시술의 종류, 시술 중 사용한 헤파린의 양, clopidogrel의 양, ticlopidine의 양, 지혈 시 수축기와 확장기혈압, ACT (activated clotting time)는 차이가 없었다. A군이 B군에 비해 시술 후 자리에 앉기까지의 시간 (A군: 4.3±0.3시간, B군: 13.7±0.8시간, p=0.004) 및 보행개시까지의 시간(A군: 6.8±0.5시간, B군: 18.8±2.1시간, p=0.013)이 유의하게 짧았다. 시술 후 주요 합병증은 두군 모두에서 관찰되지 않았으며, 경한 합병증의 전체발생은 A군에서 유의하게 적었다(A군: 28명, B군: 19명, p=0.003). 반상출혈의 경우는 A군에서 유의하게 낮았지만(A군: 3명, B군: 12명, p=0.01), 혈종, 출혈의 발생은 두군간에 차이가 없었다. 총 재원기간에는 두 군간에 차이가 없었다(p=0.239). 시술 1주 후 경과관찰에서 주요합병증은 역시 두 군 모두에서 관찰되지 않았으며, 경한 합병증의 전체발생은 두 군에서 차이가 없었다(A군: 15명, B군: 13명 p=0.418), 반상출혈의 빈도는 차이가 없었지만 혈종의 발생은 A군에서 더 낮았다(A군: 2명, B군:6명, p=0.004). 두 군 모두에서 출혈은 발생하지 않았다. 결론 : 대퇴동맥을 통한 경피적 관동맥 중재술을 시행한 환자에서 안지오실의 사용은 고식적 용수 압박법에 비해 환자의 침상 안정시간을 줄여 조기 활동개시가 가능하게 하였으며 국소합병증의 위험도를 일부 낮추어, 시술에 따른 환자의 불편을 현저하게 감소시킬 수 있다고 할 수 있을 것으로 기대된다. Background : Although the number and the quality of percutaneous coronary intervention have been recently increased dramatically, the vascular complication at puncture site is still the major cause of patients' morbidity. We evaluated the safety and efficacy of newly of newly-developed collagen-based arterial closure device, Angioseal after transfemoral percuatenous coronary intervention. Methods : This study was designed as a prospective single center non-randomized comparative study. A total 200 patients undergoing transfemoral percutaneous coronary intervention were enrolled between April 2002 and May 2003. They were divided into two groups; Angioseal group (group A, n=100) and manual compression group (group B, n=100). The baseline clinical and angiographic characteristics were reviewed. The time to sit up, the time to ambulation, the duration of hospital stay, major and minor vascular puncture site complications were monitored. The patients were followed-up for 1 week after procedure by telephone. Results : The baseline clinical characteriwtics, clinical diagnosis, cardiocascular risk factors, typesof procedure, doses and numbers of anticoagulants were similar between two groups. The blood pressure and activated clotting time were also similar. The time to sit up (group A: 4.3±0.3 hours, group B: 13.7±0.8 hours, p=0.004) and the time to ambulation (group A: 6.8±0.5 hours, group B: 18.8±2.1 hours, p=0.013) were shorter in group A. No major vascular complications were noted. The incidence of hematoma and bleeding were not significantly different between two groups. The incidence of ecchymosis, however, was significantly lower in group A (group A:12%, group B: 3%, p=0.001) The duration of gospital stay was similar between groups. During 7 days of follow-up period incidence of hematoma was significantly lower in group A (p=0.004). Although the incidence of ecchymosis was not significantly different between two groups. Conclusion : The angioseal may be associated with earlier ambulation and less patients' morbidity with low incidence of local complication rate compared to manual compression after transfemoral percutaneous coronary intervention.

There were no specific effects for test materials on Sprague-Dawley (S.D.) rats in clinical symptoms, amounts of food intakes, weight changes, laboratory findings, and pathology after whole body l, l-Dichloro-1 -fluoroethane (used as coolant, metal cleaner and solvents) exposure(0, 1,500, 3,000, and 6,000 ppm) for 13 weeks (6 hour/day, 5 days/week). However, the loss of capillary vessels in eyeball (pupil) was observed in a female rat among 6,000 ppm group. Though there was a tendency for MCHC (Mean Corpuscular Hemoglobin Concentration) in rat to be decreased (p<0.05), it was not regarded as abnormal because the values were within normal limits. In asthma-stimulation related evaluations, there was also a tendency for inflammatory cell counts in bronchoalveolar lavages to be increased. But it had no statistical significance, and also no dependency on sex and the exposed concentration. Based on this result, the non observed effect level (NOEL) induced by 1, 1-Dichloro-l -fluoroethene inhalation was evaluated in groups with 3,000 ppm below (S .D. Rats, 13 weeks). Finally, it was concluded that the short term exposal of 1, 1-Dichloro-l-fluoroethane is not considered as a asthma stimulant by inhalation despite of some study limitations such as test animals use and short-term exposure .

Before conducting the health promotion program, we surveyed the health risk appraisal(HRA) of 210 workers (186 men and 24 women) in a computer company, for the need assessment, selection of target population, priority setting, and as a standard for comparision after performing the program. The smokers were 115(88.6%), and drinkers (over 1 bottle of Soju per week) were 91(44.8%) in men. Entire women and 148(78.0%) men never or irregularly exercise. Type A personality were 73(39.2%) in men, 8(33.3%) in women, and 26(14.0%) of men and 6(25.0%) of women were high stress risk group. 53(25.2%) of men and 2(8.3%) of women were obese (BMI ≥25kg/m²), and workers who consumed exess of total calory compared with recommendation were 142(76.3%) in men and 18(75%) of women. By the health risk appraisal, it was suggested that smoking cessation program, drinking counselling, exercise prescription, stress management, and weight control program should be conducted effectively for the high risk group.

Dieulafoy's ulcer is an uncommon lesion that usually presents wih massive bleeding. Although it has been observed, for the most part, in the stomach, it has also been identified in the small bowel and colon A 35-year-old male presented with lower gastrointestinal bleeding, which was found to be caused by a Dieulafoy's ulcer in the rectum. Diagnosis was by colonoscopy. (This lesion was injected initially with endoscopic injection of a solution of hypertonic saline solution with 1/10,000 epinephrine followed by bipolar electrocoagulation.) No further bleeding has occurred with follow-up 6 months. We report one patients with extragastric Dieulafoy's lesion in the rectum.

This study was performed to evaluate the effect of persimmon vinegar on serum lipid components in the hypercholesterolemic Sprague-Dawley male rats. Forty rats were divided into four groups and fed diets containing 1% cholesterol for 4 weeks. Experimental diets added to distilled water, 1.5%, 3%, and 7% persimmon vinegar(PV) as drinking water. Concentration of total cholesterol, LDL and HDL cholesterol, triglyceride in serum and activity of AST, ALT in serum were assayed. Average food intake, weight gain and FER of experimental rats were not significantly different by contents of persimmon vinegar. Concentration of total cholesterol and LDL cholesterol in serum were lowest in 7% persimmon vinegar group. However concentration of HDL cholesterol in serum was highest in 3% persimmon vinegar group. Concentration of triglyceride in serum was significantly lower in persimmon vinegar group than control group. Activities of AST and ALT in serum were lowest in 7% persimmon vinegar group. The results in this study suggest that persimmon vinegar is effective in lowering serum triglyceride level.
