인체의 신비와 건강II-발

이경태,이우천,Lee, Gyeong-Tae,Lee, U-Cheon 한국건강관리협회 2007 건강소식 Vol.31 No.2

우리 인간의 신체는 약 206개의 뼈로 구성되어 있다. 그 중 양 발은 52개의 뼈, 38개의 근육, 214개의 인대로 형성되어 있는데, 얼마나 발이 인체에 있어서 중요한 지를 직접 느낄 수 있게 해주는 대목이다. 또한 발에는 모세혈관과 자율신경이 다른 어느 부위보다 집중적으로 분포되어 있어 발을‘제 2의 심장이다’라고 말하기도 한다. 발은 손 다음으로 많이 사용하는 부위이며 손에 비하여 육중한 무게를 지탱하는 구조로 인하여 많은 에너지를 필요로 한다. 그러므로 발끝까지 산소와 양분을 공급하는 혈관의 혈액이 원활하게 흐를 수 있게 하는 것은 건강에 있어 매우 중요한 요소이다 인체의 신비를 보여주는 우리 몸의 기관 그 두 번째, 발에 대해서 을지의대 을지병원 족부정형외과 이경태 교수, 인제대학교 서울백병원 족부클리닉 이우천 교수의 도움말로 알아본다.

Purpose: We assessed the results of open treatment of anterior impingement syndrome of the ankle in elite level soccer players and concomitant injuries were idenfied. Materials and Methods: We retrospectively reviewed twenty one elite level soccer players diagnosed with anterior impingement syndrome who underwent open debridement between January 1997 and January 2002. All were men and the mean age at the operation was 21 years (range 16 to 27). The mean follow-up duration was 31 months (13 to 71). Concomitant abnormalities were idenfied through physical examination, bone scan and MRI. On a preoperative lateral radiograph, patients were classified according to McDermott's stage. Anteromedial or anterolateral approach was used at the operation and osteophyte was removed with osteotome and rongeur. When chronic ankle instability was accompanying, we performed Modified Brostrom-Gould procedure and for osteochondral lesion, multiple drilling was applied. The Ogilvie-Harris scoring system was used as a clinical scale to evaluate pain, swelling, stiffness and limitation of activity. The results were scored as excellent (15 to 16 points), good (13 to 14) and otherwise unsatisfactory. The time to return to full activity including sports activity was determined. Results: Eighteen of twenty one patients had an excellent outcome. Three patients were graded unsatisfactory and two of them abandoned their career due to the persistence of residual pain. Concomitant abnormalities were found including twelve cases of chronic ankle instability, three cases of osteochondral lesion and two cases of flexor hallucis longus tendinitis. Conclusion: Open debridement was successfully applied to the elite level soccer player with anterior impingement syndrome of the ankle. Considerable coexistence of other abnormalities such as chronic ankle instability may encourage us to consider additional operative procedure.

This experiment was performed in order to study the effects of Haepyoyijintang on the pulmonary injury caused by $SO_2$. Healthy adult male rats weighting about 250g were divided into 4 groups- the Normal group, the Control group, the group of Haepyoyijintang administration for 5 days after $SO_2$ gas exposure (Sample I ), and the group of Haepyoyijintang administration for 10 days before and for 5 days after $SO_2$ gas exposure (SampleⅡ). The results were obtained as follows; 1. In the total number of leucocyte, Sample I and Sample II decreased significantly compared with Control group. 2. In the erythrocyte sedimentation rate, Sample I and Sample Ⅱ decreased significantly compared with Control group. 3. In the lung weight, Sample I and Sample II decreased significantly compared with Control group. 4. In the lung TBA level, only Sample II decreased significantly compared with Control group. 5. In the tracheal glycoprotein level, Sample I and Sample II decreased significantly compared with Control group. According to the above results, Haepyoyijintang has significant effects on the pulmonary injury caused by $SO_2$ in rats.

Purpose: The purpose of this study was to evaluate the result of modified Lapidusprocedure for Hallux valgus associated with first ray hypermobility Materials and Methods: A retrospective study was conducted between Aug. 1999 and Oct. 2003. We evaluated 20 cases (12patients)of hallux valgus that performed modified Lapidus procedure. We asked to patient about postoperative satisfaction in terms of overall, pain, and appearance. preoperative and postoperative AOFAS score for the forefoot was calculated, also preoperative and postoperative radiologic evaluation was done. Results: In terms of satifaction, overall rate was 70%, pain relief and appearance were 70% and 70%. preoperative mean Hallux valgus angle and mean intermetatarsal angle were 42.6degree and 19.4degree. after procedure, at last follow up, mean hallux valgus angle and mean intermetatarsal angle were 16degree and 8.7degree. In terms of complication, nonunion was seen in 3 cases and recurrence of hallux valgus deformity was 2 cases. Conclusion: In consideration of high complication rate, modified Lapidus prociduremust be improved in terms of more rigid fixation technique, etc.

Purpose: The aim of this study is to evaluate the effectiveness of surgical treatment in adolescent patients suffering from navicular stress fracture. Materials and Methods: A total of 11 adolescent patients aged 14 to 19, who underwent an operation for navicular stress fracture between 2005 and 2008 were recruited. Clinical outcomes were evaluated by the American Orthopaedic Foot and Ankle Society (AOFAS) midfoot score and visual analogue scale (VAS) score. Results: The mean VAS score before the operation was 7.7. A score of 2.9 was confirmed at final follow up after the operation. The mean final follow-up period was 22.1 months. There was a statistically significant improvement in the VAS score between before and after the operation (p=0.01), and similarly, the AOFAS score also showed an improvement, from 46.5 to 80.7 (p=0.01). The pain that remained after the operation, according to the VAS score, was severe in three patients (27.3%), tolerable in seven patients (63.6%), and free of pain in one patient (9.1%). Conclusion: In navicular stress fracture in adolescents, careful selection of patients who could benefit from surgical treatment is recommended.

목적: 국내 프로 축구팀에서 시즌 전 체력검사를 시행하여 포지션에 따른 자료를 분석하고 표준화하고자 했다. 대상 및 방법: 34명으로 구성된 한 개의 축구팀을 대상으로 시행하였으며 평균 나이 24.9세였다. 설문지를 통한과거 병력 조사, 이학적 검사를 통한 근 골격계 검사, 등속성 근력기기를 이용한 근력 검사, 생리적 검사, 기능적 검사를 시행하고 포지션에 따른 차이를 분석하였다. 결과: 과거력 상 슬관절 손상이 23예 중 11 예(47%)로 가장 빈번했고, 이학적 검사 결과 총 40예 중 족관절 손상이 14예 (46%)로 슬관절 손상 11예 (24%)보다 많은 손상이 있었다. 위치 별로 공격수는 장무지 굴곡 건염, 미드필드는 만성 족관절 불안정성 수비수는 아킬레스 건염이 많았고 근력 검사상 우세 $60^{\circ}$ 신전/굴곡 체중당 최대 염력비 평균이 55.1%였다. 생리학적 검사상 미드필드 체 지방율이 17.8% (표준편차 2.9)로 높게 측정되었고 기능적 검사 결과 배근력 125.5N (표준편차 28.3), 서전트 점프 59.6cm, 반응시간 208 5초, 유연성 19.2 m/s, 사이드 스텝 39.9 cm였다. 결론: 시즌 전 체력검사를 통하여 선수들의 체력을 평가하고 이를 기초로 하여 재 손상에 대한 예방적 수단을 강구 할 수 있다. Purpose: In the professional soccer team, we performed pre-seasonal physical examination and analyzed the results to establish a standardization data in relation to their position. Materials and Methods: We performed physical examination to the professional soccer team, consisted 34 player's average age 24.9 years. The examination performed were questionnaire on history, musculoskeletal examination, muscle power test, physiologic test, functional test. Results: According to the relationship between player position and injury pattern,. Knee injuries are most frequent on history. Physical examination outcome was that forward were prone to flexor hallucis longus tendinitis, midfielder for chronic ankle instability, defender for achilles tendinitis. Isokinetic test was done at dominant side, Peak torque to body weight ratio was 55.1%. Physiologic test checked body fat percentage was midfielder was superior as 19.8 (SD 2.9). Functional test out-come was that back strength 125 N. sergeant jump 59.6 cm, reaction time 208.5 sec, flexibility 19.2 m/s, side step 39.9 cm.

In the previous report, E-kong-san, which is usually used for recovering health in traditional medicine, has been shown to decrease cisplatin induced nephrotoxicity in vivo and in vitro. The significant reduction of E-kong-san on the cisplatin induced nephrotoxicity led us to investigate whether the effect of this water extract was a result of triggering antioxidation. In monkey kidney Vero cells, E-kong-san at $5{\sim}10\;mg/ml$ was able to attenuate 2mM cisplatin-stimulated cell death by 46.8% and 31.8%, respectively. E-kong-san showed strong free radical scavengering activities on 1,1-diphenyl-2-picrylhydrazil (DPPH) radical and xanthine/xanthine oxidase (XOD) generated superoxide anion radical $(O_2^{-.})$. We further studied the effects of E-kong-san on lipid peroxidation in rat liver microsomes induced by enzymatic and nonenzymatic methods. Moreover, E-kong-san exhibited significant inhibition on both ascorbic $acid/Fe^{2+}$ and $ADP/NADPH/Fe^{3+}$ induced lipid peroxidation in rat liver microsomes. Based on these results, we suggest that E-kong-san protects the cisplatin induced cytotoxicity by its antioxidative mechanism.
