The radial artery superficial palmar branch free flap is based on the perforators of the superficial palmar branch of the radial artery and its venae comitantes. This flap can be used as a sensible flap including palmar cutaneous branch of the median nerve. Forty radial artery superficial palmar branch free flaps were performed at Centum Institute during October 2010 to December 2011. There were 32 males and 8 females and their mean age were 48 years (range 30 to 66 years). The thumb injured in 13 patients, the index finger in 16 patients, the middle finger in 4 patients, the ring finger in 2 patients, and the little finger in 5 patients. The mean size of the flap was $2.5{\times}3.5$ cm(range $2{\times}2.5$ to $3{\times}7$ cm). The donor site was always closed primarily. The overall survival rate was 90.2 percent. The flaps showed well-padded tissue with glabrous skin. All patients have touch sensation and showed 12 mm two point discrimination in an average(range 8 to 15 mm). Donor site morbidity was conspicuous. One patient showed unsightly scar. Early postoperative range of motion of the affected thumb showed slightly limited radial and palmar abduction. But it improved after postoperative 2 months, and patients did not complaint limitation of motion. In conclusion, the radial artery superficial palmar branch free flap can be used as an option for soft tissue reconstruction of finger defects where local or island flaps are unsuitable.

In studying the specific effects of some drugs, animals under experiments get some stress through laboratory environments, drug injection, and adaptation period. These stimuli do harms on liver function. Nowadays studies on liver intoxication and its protection are under research, but the function of dissolution is rarely under studies. It is widely accepted that Soshiho-tang has function of clearing away low spirits, and that it enables liver bloods to move stronger, and to have calm mind. So I injured rats liver by injectioning CCI₄. And the rats took in Soshiho-tang solution. I made a comparison between the functions before and after rat's liver damage. There are many representative serums used to note an index on liver damage. I used total protein, albumin, ALP, GOT, GPT activity, P450, SOD, Catalase, GST, GR, and GPx. I got the following results. When Soshiho-tang was injected after CCI4 intoxication, total protein and albumin decreased. When Soshiho-tang was injected, ALP decreased, compared with control group. When Soshiho-tang was injected after CCI₄ intoxication, AST and ALT decreased. When Soshiho-tang was injected before CCI₄ intoxication, P450 was restrained. When Soshiho-tang was injected, LPO was all restrained. When Soshiho-tang was injected, SOD, Catalase, GST, GR, and, GPx increased. These results show that blood test reveals that it is good to inject Soshiho-tang after CCI₄ intoxication, but that it is good to inject Soshiho-tang before CCI₄ intoxication in case of P450, LPO, SOD, Catalase, GST, GR, and GPx. It is estimated that the medication period and time of liver damage by CCI₄ have counter results, and that it needs more modified study.

Pivampicillin hydrochloride is a kind of broad spectrum antibiotics with bactericidal action, and is used in many countries, although it has bitter taste, unpleasant odour and side effects of irritating gastric mucosa, nausea, penicillin allergy, etc. For the improvement of such side effects of pivampicillin hydrochloride, microcapsules, with wall of ethylcellulose, have been prepared by coacervation method. The shape was observed through the scanning electron microscope, the release of the drug into an aqueous medium was studied and the effects of core: ethylcellulose ratio were interpreted as well as making sensory evaluation of taste and odour. There was decreasing trend in dissolution rate of the drug with the increase of core: ethylcellulose ratios, and the smaller microcapsules released their contents more rapidly. A linear relationship was established between the amount of ethylcellulose and the time for 60% release of the drug, and the release pattern was found to have similar characteristics to the release of the drug from an insoluble porous matrix. The release of the drug in the artificial intestinal fluids (pH 6.8) was found to be similar to that in water, while the release in the artificial gastric juice (pH 1.2) was slightly slower. Bioavailability of microcapsule was compared with that of pivampicillin hydrochloride in rabbits using serum concentration and urinary excretion measurements. Microcapsule gave showed slightly higher serum level than pivampicillin hydrochloride from 2 hours after administration, while no significant difference was observed in the accumulated urinary excretion rate between pivampicillin hydrochloride and microcapsule. The ulcer index of pivampicillin hydrochloride administered group was 2.6, and microcapsule administered group was 1.5, while control group was 0.8. Therefore it may be concluded that microencapsulation of pivampicillin hydrochloride is a useful pharmaceutical approach to protect the gastrointestinal tract from being injured by direct contact of pivampicillin hydrochloride without any significant difference of bioavailability.

Despite the movement of safe traffic by the Korean government to reduce deaths in traffic accidents, the casualties increase year by year. In particular, more and more accidents and casualties are reported from car collisions from the back of the vehicles parked for managing traffic accidents on the road, cleaning main roads and medial strips, repairing roads. In order to response to these accidents, the government should take protective measures for road users. In the last decade, seventy-one cases have been reported to occur during highway repair and maintenance. As a result, eight persons were killed and seventy-six were injured, showing the high death rate of 11.3 percent. Therefore, it seems urgent to take some actions against it. The United States and European countries legislate that vehicles of road repair and maintenance should be mandatorily equipped with shock absorber at the back. Korea, however, does not have such legislative measures, which are needed at this time to protect workers on the road. This study compares the performance of the traditional shock absorber for road maintenance vehicles with that of the rear safety guard using air bag, manufactured in accordance with related laws in Korea. Based on the results of the 60km/h rear collision test, this paper proposes improvements in related laws and regulations in an attempt to reduce casualties.

Background Nonabsorbable sutures are favorable for repairing flexor tendons. However, absorbable sutures have performed favorably in an animal model. Methods Two-strand sutures using the interlocking modified Kessler method with polydioxanone absorbable sutures 4-0 were used to repair completely ruptured flexor tendons in 55 fingers from 41 consecutive patients. The medical records of average 42 follow up weeks were analyzed retrospectively. The data analyzed using the chi-squared test, and Fisher's exact test was used for postoperative complications. The results were compared with those of other studies. Results Among the index, middle, ring, and little fingers were injured in 9, 17, 16, and 13 fingers, respectively. The injury levels varied from zone 1 to 5. Of the 55 digits in our study, there were 26 (47%) isolated flexor digitorum profundus (FDP) injuries and 29 (53%) combined FDP and with flexor digitorum superficialis injuries. Pulley repair was also conducted. Concomitant injuries of blood vessels and nerves were found in 17 patients (23 fingers); nerve injuries occurred in 5 patients (10 fingers). Two patients had ruptures (3.6%), and one patient had two adhesions (3.6%). Using the original Strickland criteria, all the patients were assessed to be excellent or good. Also, fibrosis and long-term foreign body tissue reactions such as stitch granuloma were less likely occurred in our study. Compared to the Cullen's report that used nonabsorbable sutures, there was no significant difference in the rupture or adhesion rates. Conclusions Therefore, this study suggests that appropriate absorbable core sutures can be used safely for flexor tendon repairs.

Purpose: This study investigated the epidemiology, management, outcomes, and postoperative disabilities of degloving soft tissue injuries (DSTIs) treated at a tertiary care center in northern India. Methods: A prospective study of patients with DSTIs was conducted over 15 months. The type of degloving injury, the mechanism of injury, and any associated injuries were analyzed using the World Health Organization Disability Assessment Schedule (WHODAS) 2.0 along with the management, outcomes, and disabilities at a 3-month follow-up. Results: Among 75 patients with DSTIs, the average age was 27.5 years, 80.0% were male, and 76.0% had been injured in traffic accidents. The majority (93.3%) were open degloving injuries. Lower limbs were affected most often (62.7%), followed by upper limbs (32.0%). Fractures were the most commonly associated injuries (72.0%). Most patients required more than two procedures, including secondary debridement (41.3%), split skin grafting (80.0%), flap coverage (12.0%), or vacuum-assisted closure (24.0%), while five patients underwent conservative management for closed degloving injuries. Postoperative complications included surgical site infections (14.7%) and skin necrosis (10.7%). Two patients died due to septic shock and multiple organ dysfunction syndrome. The mean length of hospital stay was 11.5±8.1 days, with injuries affecting the lower limbs and perineum requiring longer hospital stays. The mean WHODAS 2.0 disability score at 3 months was 19. Most patients had mild disabilities. Time away from work depended largely upon the site and severity of the injury. Approximately 75% of patients resumed their previous job or study, 14% changed their job, and 8% stopped working completely due to residual disability. Conclusions: DSTIs are common injuries in trauma and management is challenging. Although open DSTI are clinically evident at secondary survey, closed degloving injuries may be missed in the primary survey, necessitating a high index of suspicion, thorough clinical examination, and protocol-based management. Primary preventive strategies (e.g., road safety protocols, preplacement training, and proper protective equipment in industries) are also needed to reduce the incidence of these injuries.

목적: 현재까지 군에서 발생하는 총기 및 폭발물 손상은 그 중요성에 비해 연구된 것이 제한적이었다. 이를 극복하기 위해 최근 4년간 총기 및 폭발물에 의해 수상한 군인 환자의 근골격계 손상에 대한 특징을 확인하고자 하였다. 대상 및 방법: 2015년 1월부터 2019년 7월까지 총기 및 폭발물에 의해 근골격계 손상을 당한 군인 환자를 대상으로 하였다. 의무 기록과 의료영상저장전송시스템 영상자료를 분석하고, 전화 면담을 통해 short musculoskeletal function assessment (SMFS)를 이용한 기능평가를 후향적으로 시행하였다. 기능평가에 대한 통계 분석으로 무기종류에 따른 분석은 t-test를, 다른 요인에 따른 분석은 ANOVA 분석을 실시하였다. 결과: 총기 및 폭발물에 의한 손상으로 치료받은 총 61명의 환자 중 30명(49.2%)이 근골격계 손상으로 정형외과적 치료를 시행받았다. 평균 수상 나이는 26.4세(21-52세)였다. 간부와 병사의 수는 비슷하였다. 총기 손상이 11명, 폭발물 손상이 19명이었다. 30명 중 수도병원에서 16명(53.3%)이, 민간병원에서 10명(33.3%)이 치료받았다. 12명에게 복수부위 손상이 있었고, 골절이 동반된 16명(53.3%)의 환자 중 절반 이상인 7명의 환자가 다발성 골절이었다. 수부와 하퇴부가 가장 흔한 수상 부위였다. 2명을 제외하고는 모두 개방창이 있었으며, 연부조직 재건술이 필요한 환자는 14명(46.7%)이었다. SMFS 기능평가에는 15명이 응답하였다. 계급에 따른 분석 결과, Borther Index에서 간부의 결과가 통계적으로 유의하게 낮은 것으로 분석되었다(p=0.05). 치료 병원에 따른 분석 결과, Dysfunction Index와 Bother Index 모두 수도병원에서 치료 받은 인원의 점수가 통계적으로 유의하게 낮은 것으로 분석되었다. (p=0.0008, p=0.0149) 결론: 국내 무기에 의해 수상한 군인 환자에 대해 분석한 첫 연구이다. 무기 손상 환자의 치료에 있어 orthopedic burden이 높음을 확인하였으며, 장기적으로 이런 환자들에 대한 치료평가 및 군 외상 시스템 발전을 위해 총기 및 폭발물에 의한 손상 환자를 포함한 군 외상환자 레지스트리 구축이 필요하겠다.
