Background and ObjectivesThe use of ballistic movements during resistance exercises can improve the efficiency of force and change the momentum and muscle activity due to the selective mobilization of the motor unit. This study was conducted to analyze the number of repetitions, exercise time, and body muscle activity during traditional resistance and ballistic resistance exercises.Materials and MethodsEight males in their 20s were selected as the study subjects and two exercise types (non-ballistic, ballistic) were performed. The following results were obtained by measuring the number of repetitions, exercise time, and the electromyography (EMG) response during exercise.ResultsFirst, there was a statistically significant difference in the number of repetitions with the ballistic movement during the standing shoulder press (p = .037). Second, there was a statistically significant difference in the exercise time with the ballistic movement during the standing shoulder press (p= .042). Third, there was a statistically significant difference in the erector spinae (p = .002), rectus femoris (p = .001), gastrocnemius (p = .012) activity with the ballistic movement during the standing shoulder press.ConclusionIt was confirmed that muscle activity and power output could be changed with the use of ballistic movements.

연구배경 : 급성 및 만성 백혈병에서 동종 골수이식을 시행할 경우 이식 당시의 임상상태는 이식후 생존율에 영향을 미치는 가장 중요한 요소중의 하나로서, 1차 관해시 혹은 조기에 이식을 할수록 진행된 상태 혹은 말기 상태에서 이식을 실시하는 경우에 비해 생존율이 높다고 한다. 저자들은 이식당시의 임상상태가 골수이식후 생존율에 미치는 영향을 분석하기 위하여 동종 골수이식을 받은 급성 및 만성 백혈병 환자들을 질환별로 표준 위험군과 고 위험군으로 분류하여 두 군간의 장기 무병생존율을 비교함으로써 이식시 관해상태와 이식후 장기생존율간의 관계를 알아보고자 하였다. 방법 : 1983년 3월부터 1990년 12월까지 가톨릭의대 부속 성모병원에서 조직적합항원(HLA)이 일치하는 형제자매로부터 동종골수이식을 시행한 58명의 급성 및 만성백혈병환자들을 대상으로 이식 당시의 임상상태에 따라 표준 위험군과 고 위험군으로 분류하여 두군간의 생존율을 후향적으로 비교하였다. 표준 위험군은 AML 및 성인형 ALL에서는 1차 관해, 소아형 ALL에서는 2차 관해까지, 그리고 CML 에서는 만성기에 이식을 시행한 경우로 하였고, 그외의 진행된 상태나 재발된 경우에 이식을 실시한 경우는 모두 고 위험군으로 분류하였다. 결과 : 1) 3개월부터 55개월(중앙치 26개월)까지 관찰한 결과 1차 관해시 이식한 AML(표준 위험군) 13명중 8명(62%) 이 생존하였고, 2차 관해 이상의 상태에서 이식한 AML(고 위험군)은 10명중 1명(10%)만 생존하여 통계학적으로 유의한 차이를 보였다(p<0.01). 2) 3개월부터 93개월(중앙치 36개월)까지 관찰한 결과 성인형 ALL은 1차 관해에서 이식을 시행한 6명중 4명(67%)이 생존하였고, 2차 관해 이상의 시기에 이식한 경우는 5명중 3명(60명)이 생존하여 통계학적인 차이는 없었다(p=0.2). 또한 소아형 ALL은 2차 관해이전(표준 위험군)에 이식을 시행한 4명중 3명(75%)이 생존하였고, 고 위험군에 속하는 예는 없었다. 3) 3개월부터 52개월(중앙치 36개월)까지 관찰한 결과 CML은 만성기(표준 위험군)에 이식을 시행한 9명중 8명(89%)이 생존하였고 가속기나 급성기에 이식을 시행한 경우는 11명중 4명(36%)이 생존하여 통계학적으로 유의한 차이를 보였다(p<0.01). 4) 표준 위험군에 속하는 백혈병에서는 32명중 23명이 생존함으로써 72%의 생존율을 보인반면, 고 위험군에서는 26명중 8명이 생존하여 31%의 생존율을 보였다(p<0.01). 5) 전체 대상환자 58예중 28예가 사망하였는데 사망원인으로는 백혈병 재발이 15예로 가장 많았으며 급성 이식편대 숙주반응이 4예, 생착부전 2예, 거부반응 1예, 간질성 폐염 1예, 패혈증 2예, veno-occlusive disease 1예, 급성 신부전 1예, 그리고 TTP-like syndrome 1예등이었다. 결론 : 이상의 결과로 급성 및 만성 백혈병에서 골수이식을 시행할 경우 이식시 임상상태로 표준 위험군(1차 관해, 만성기)에 속하였을때 장기생존율이 증가됨을 알수 있었으며, 향후 이식후 생존율을 향상시키기 위하여 이식의 시기는 1차 관해 혹은 만성기, 즉 조기에 시행하는 것이 바람직하리라고 사료된다. Background: To assese the relationship between disease status at transplant and long-term disease-free survival (DFS) in patients with acute and chronic leukemia, we compared the DFS of standard risk group ad that of high risk group after allogeneic bone marrow trasplantation (BMT). Methods: Between March 1983 and December 1990, 58 patients with acute or chronic leukemia who had been underwent the allogeneic BMT at St. Mary`s Hospital of Catholic University Medical College were assigned to a retrospective study comparing DFS of standard risk group withe that of high risk group. We defined standard risk group(n=32) as the first complete remission(CR) in AML or ALL of adult type, the second CR or ALL of childhood type and the chronic phase of CML. Advanced disease state beyond the standard risk group was considered as high risk group (n=26). Results: 1) In AML, after median follow-up of 26 months (3~55 months) long-term DFS of standard risk group was higher (62%) than that of high risk group (10%) (p<0.01). 2) In ALL of adult type, after median follow-up of 36 months(3~93 months) long-term DFS between standard risk and high risk group was 67% and 60%, respectively(p=0.2). 3) In CML, after median follow-up of 27 months (3~52 months) long-term DFS of standard risk group was 89% and that of high risk group was 36% (p<0.01). 4) Compared to the 72% (23/32) survival rate of standard risk leukemia, that of high risk leukemia was 31%(8/26)(p<0.01). 5) Relapse of leukemia was the most frequently encountered complication (29%) and the most common cause of death (54%) after allogeneic BMT. Conclusion: Our results show that the outcome of standard risk group appears to be superior to that of high risk group in patients with acute and chronic leukemia. Therefore we would like to recommend to perform BMT in the early stage of disease for the treatment of acute and chronic leukemia to improve the long-term DFS.

Subacute thyroiditis is a frequent benign thyroid disease associated with previous viral upper respiratory tract infection. Known complications of this disease are long-standing subclinical hypothyroidism, persistent anterior neck pain and rarely Graves disease. In general, thyroid abscess is an uncommon disease because of anatomic isolation of the gland and its rich system of drainage for blood and lymph. Especially, development of thyroid abscess in subacute thyroiditis is extremely rare phenomenan, but significant bad outcomes can be resulted. Its clinical background containes immune-suppressed state, anatomic defect, presence of underlying other thyroid disease and of non-thyroidal infectious foci. We experienced a case of subacute thyroiditis complicated with streptococcal thyroid abscess during glucocorticoid therapy. The patient was a 19-year-old female who was admitted due to anterior neck pain for 1 month. Typical subacute thyroiditis was suggested from initial laboratory findings including CBC, erythrocyte sedimentation rate, serum T3, T4, TSH levels, thyroid scan & thyroid uptake. But during oral prednisolone therapy, unexpected bacterial thyroid abscess was developed. We report this unusual case with review of literatures. (J Kor Soc Endocrinol 12;468-472, 1997)

Hypersensitivity pneumonitis is an immune-mediated inflammation of the pulmonary parenchyma secondary to the inhalation of sensitizing agents such as fungi, bacteria, and chemical substances. Genetics and environments have been regarded as predisposing factors in familial studies. In Korea, there has been no case report of familial hypersensitivity pneumonitis in spite of many reports of familial hypersensitivity pneumonitis in other countries. We present a first case of the familial hypersensitivity pneumonitis in Korea diagnosed by the clinical history, various laboratory findings and an open lung biopsy.

배경: 레트로졸은 유방암 치료에 사용되는 경구용 비스테로이드성 aromatase 억제제이다. 방법: 이 연구는 건강한 성인 남성을 대상으로 무작위 배정, 단회 투여, 공개설계로서 두 치료군, 두 순서, 두 시기의 교차 시험법으로 진행되었다. 각 순서군에 13명씩 무작위 배정되어, 한군은 1기에 페마라$^{(R)}$정(대조약)을, 2기에 유한 레트로졸정(시험약)을, 다른 한군은 반대 순서로 두 시기 사이에 약 5주의 휴약기를 가지고 각각 2.5 mg정 1정씩 투여 받았다. 약동학 분석을 위한 혈액 검체는 공복 상태에서 투약 후 312 시간까지 얻어졌다. 레트로졸의 혈장 내 농도는 liquid chromatography-tandem mass spectrometry를 이용하여 측정하였다. 안전성 평가는 활력징후, 문진 및 신체검사, 심전도, 진단검사실 검사와 이상반응 모니터링을 통하여 이루어졌다. 결과: 총 26명의 피험자가 연구를 완료하였고, 약동학 분석에 26명의 자료가 모두 사용되었다. $C_{max}$와 $AUC_{last}$ 파라미터에 대한 시험약과 대조약의 기하평균비는 각각 0.92 (90 % 신뢰구간: 0.85 - 0.99)와 1.01 (90 % 신뢰구간: 0.97 - 1.04)였다. 보고된 중대한 이상반응은 없었으며, 임상적으로 유의한 변화도 관찰되지 않았다. 결론: 건강한 자원자에서 페마라$^{(R)}$정과 유한 레트로졸정의 약동학 특성과 안전성은 유사하였다. Background: Letrozole is an oral non-steroidal inhibitor of the aromatase enzyme, which has proven to be a useful drug against breast cancer. Methods: This single-dose, randomized $2{\times}2$ crossover study was conducted in healthy male volunteers. Participants of each sequence group (each 13 volunteers for sequence group) received, in randomized sequence, a single oral 2.5-mg dose of generic letrozole (test) or branded letrozole (reference). Each treatment period was separated by a 5-week washout period. Blood samples were collected for up to 312 hours after drug administration, and drug concentrations were determined using validated LC/MS-MS. Pharmacokinetic properties were obtained using noncompartmental analysis. Drug tolerability was assessed throughout the study, using measurements of vital signs, physical examination, clinical chemistry testing, EKG, and interviews. Results: A total of 26 subjects completed the study. The geometric mean ratios (90% CI) of $C_{max}$ and $AUC_{last}$ were 0.92 (0.85 - 0.99) and 1.01 (0.97 - 1.04), respectively. No serious AEs were reported, and there were no clinically significant differences between test and reference groups. Conclusion: The findings from this study suggest bioequivalence between two formulations of letrozole in healthy male volunteers. The safety profile of two formulations had similar characteristics.
