극동산 뱀장어(Anguillla japonica)의 대체어종으로 필리핀산 뱀장어(Anguilla bicolor pacifica)의 양식기술을 개발하기 위해 필리핀산 실뱀장어를 대상으로 먹이순치 및 적정 사육밀도에 대하여 알아보았다. 입붙임 사료를 4, 6, 8, 10배 공급한 계에서 성장도 및 생존율이 서로 비슷하였으며, 입붙임 사료의 공급일수가 5, 10, 15일에서도 그 성장률과 생존율은 서로 간에 명확한 차이는 없었다. 그리고 사육 밀도 실험에서 469 마리/㎡에서 성장 속도가 가장 높게 나타났으며, 극동산 뱀장어와 큰 차이는 없었다. 따라서 양만장에서 필리핀산 뱀장어를 사육할 경우 입붙임 사료의 공급 양은 4배, 일수는 5일, 밀도는 469 마리/㎡가 가장 적당한 것으로 나타났다. Initial feed rate and farming density of the Philippines grass eels, Anguilla bicolor pacifica were studied to obtain the optimal culture method as alternative species for Japanese eel, Anguilla japonica. There were no difference at growth and survival rate among feeding rate and feeding days for initial feed. The highest growth rate was observed at 469 ind./㎡ in eel density for initial feed, and this results was similar to that of Anguilla japonica. It seems most appropriate that four times in amount of initial feed, 5 days in period of initial feed, and 469 ind./㎡ in its density are sufficient to breed Philippines grass eels, Anguilla bicolor pacifica.

A feeding trial was conducted to determine the optimum dietary protein and lipid levels for the growth of juvenile muddy loach Misgurnus anguillicaudatus. Eight experimental diets (designated as P20L7, P20L14, P30L7, P30L14, P40L7, P40L14, P50L7 and P50L14) were formulated to contain 20%, 30%, 40% and 50% protein with 7% and 14% lipid. Three replicate groups of muddy loach (1.5 g/fish) were fed one of the experimental diets ad libitum for 8 weeks. Survival of fish fed the P20L14 diet was lower than in other groups (P<0.05). Specific growth rate (SGR) and feed efficiency (FE) of fish were affected by dietary protein (P<0.05) and lipid (P<0.005) levels. SGR and FE of fish tended to decrease with increasing dietary lipid level at the same protein level. There were no significant differences in SGR and FE among fish fed diets containing different protein levels ranging from 30% to 50% with the same lipid level. Whole body moisture and lipid contents were affected by dietary protein and lipid levels. Crude lipid content of fish fed the 14% lipid diets was higher than that of fish fed 7% lipid diets at each protein level. The results of this study indicate that a diet containing 30% protein with 7% lipid would be suitable for the optimum growth and effective feed utilization of juvenile muddy loach.

Two feeding trials were conducted to evaluate the effects of experimental extruded pellets (EEPs) and commercial EPs (CEPs) on Far Eastern catfish Silurus asotus in pilot- (experiment I) and commercial-scale (experiment II) tanks. Four diets were prepared: three EEPs (EEP1, EEP2 and EEP3) that contained different amounts of tuna fish meal, soybean meal, and squid liver oil, and one CEP diet. In experiment I, three replicate groups of juveniles were fed one of the four EPs in pilot-scale tanks for 19 weeks. The weight gains (WGs) of fish fed EEP1 and CEP were significantly higher than those of fish fed EEP2 or EEP3. The highest feed efficiency (FE) was observed in fish fed the CEP diet (P<0.05), and the FE of fish fed EEP1 and EEP3 were significantly higher than that with EEP2 (P<0.05). In experiment II, juveniles were fed one of four EPs in commercial-scale tanks for 19 weeks. WG and FE values of fish fed EEP1 and CEP were higher than those of fish fed EEP2 and EEP3. The results of this study indicate that the dietary formulation used in EEP1 could be used as a practical feed for Far Eastern catfish.

Purpose: Facial allotransplantation (FA) could provide an excellent alternative to current treatments for facial disfigurement. However, despite being technically feasible, there continues to be various ethical and psychosocial issues associated with the risks and benefits of performing FA. The purpose of this study is to investigate risk acceptance and expectations in FA. Methods: In a quantitative assessment of risk versus benefit with respect to FA, from 2004 to 2008, Barker et al. developed and published a questionnaire-based instrument (Louisville Instrument for Transplantation [LIFT]), which contained 237 standardized questions. In the current study, the authors assessed risk versus benefits and expectations of FA using a Korean version of the LIFT. Respondents in three study groups (lay public, n=140; medical students, n=120; doctors, n=34) were questioned about risk acceptance as related to immunosuppression and tissue rejection, and expectations as related to quality of life improvement, and functional and aesthetic outcomes. A summary of the data has been provided and statistical analyses were performed. Results: Among the three study groups, results indicated that doctors accept the least amount of risk for a facial allotransplant, followed by medical students, and finally lay public. There was a significant statistical difference in three of the four questions regarding risk acceptance between the groups (p < 0.05). In general, lay public exhibited higher expectations for facial allotransplantation than the other groups. Additionally, there was a significant statistical difference in the importance of aesthetic outcome between the groups (p < 0.05). Conclusion: The authors' data indicate the three populations have vastly different levels of risk acceptance and expectations with regard to FA. Therefore, it is very important that surgeons establish clear, open, and thorough communication with patients in their consultations regarding FA. This is particularly important with respect to whether or not a patient's level of risk acceptance and expectations are progmatic.

김진희,권준영,송준영,오윤경,김광석,허준욱,Kim, Jin Hui,Kwon, Joon Yeong,Song, Jun Young,Oh, Yun Kyeong,Kim, Kwang Seog,Hur, Jun Wook 한국해양생명과학회 2019 한국해양생명과학회지 Vol.4 No.2

수산자원보호구역인 춘천호와 안동호에서 어류 군집 분석을 실시하였다. 조사는 2017년부터 2018년까지 수행되었으며, 어류상을 파악하고 우점종 및 아우점종을 확인한 결과 춘천호에서 채집된 어류는 총 13과 34종 1,197개체였다. 채집된 어류 중 블루길(Lepomis macrochirus)이 23.2%로 우점하였으며, 피라미(Zacco platypus)가 17.4%로 아우점하였다. 안동호에서 채집된 어류는 총 9과 24종 1,393개체였다. 우점종은 블루길이 15.7%로 가장 많이 채집되었으며, 붕어(Carassius carassius)가 15.2%로 아우점하였다. 두 조사지점의 종다양도는 과거보다 증가하는 경향을 보였으며, 균등도는 안동호에서는 차이가 보이지 않았으나 춘천호에서는 증가하는 경향을 보였다. 두 인공호 모두 어류상 및 군집구조 측면에서 안정된 상태를 유지하고 있으나 외래종 비율을 감소시키기 위한 지속적인 노력이 필요하고, 다양한 어종이 안정적으로 개체수를 유지할 수 있도록 수산자원 종자 방류 및 인공산란장 설치 등과 같은 관리가 필요하다. Ichthyofauna and community structure of fish were studied for two fisheries resource reserves, Chuncheon reservoir and Andong reservoir from 2017 to 2018. Fish were sampled 8 times at each reservoir. In Chuncheon reservoir, total number of fish sampled was 1,197 representing 34 species and 13 families. Dominant species and sub-dominant species were Lepomis macrochirus (23.2%) and Zacco platypus (17.4%), respectively. In Andong reservoir, total number of fish sampled was 1,393 representing 24 species and 9 families. Dominant species and sub-dominant species were L. macrochirus (15.7%) and Carassius carassius (15.2%), respectively. The diversity index of two sampling site increased compared to previous investigation. The evenness index was not changed much in Andong reservoir but increased in Chuncheon reservoir. Ichthyofauna and community structure of fish at sampling sites in both reservoirs maintained stable except high proportion of exotics species with needed to be reduced by consistent effort. For better fish population in these communities, however, various efforts such as seed stocking and installment of artificial spawning ground should be provided to these reservoirs.

Purpose: Epidermolysis bullosa is a rare genetic disease, characterized by the presence of extremely fragile skin and formation of recurrent blister resulting from even a minor mechanical injury. Squamous cell carcinoma (SCC) is recognized as a complication of the chronic scarring associated with dystrophic epidermolysis bullosa (DEB). When a soft tissue defect happens in a patient with epidermolysis bullosa, it is difficult to cover it with a skin graft or a flap. We describe the successful use of a pedicled deep inferior epigastric perforator flap for the reconstruction of SCC associated with DEB in the groin. Methods: A 29-year-old man diagnosed with DEB at birth sustained an ulcer increasing in the right groin for the last 7 months. Under general anesthesia, the mass lesion and lymph nodes were removed and the resulting defect was covered with a pedicled deep inferior epigastric perforator flap. Results: The flap survived completely and his postoperative course was uneventful. Histopathological examination revealed a SCC in the right groin and malignant tumor cells in the removed lymph nodes as well. Additional positron emission tomogram showed a malignant lesion in the ileocecal area with regional lymph node metastasis. The patient was referred to an oncologist for chemotheraphy, but the patient refused to take it. During a 4-month follow-up period, there was no recurrence in the right groin. Conclusion: We suggest that perforator flaps can be considered as a reliable alternative for the reconstruction of soft tissue defects in a patient with DEB.

V-M 성형술을 이용한 지간구축 및 합지증의 교정 임상례

김의식,박상렬,황재하,김광석,이삼용,Kim, Eui-Sik,Park, Sang-Ryul,Hwang, Jae-Ha,Kim, Kwang-Seog,Lee, Sam-Yong 대한성형외과학회 2010 Archives of Plastic Surgery Vol.37 No.1

Purpose: The loss of web space is caused by congenital syndactyly or acquired burn injury, trauma or surgery. Numerous surgical procedures have been described for restoration of the web space. Local flaps are usually preferred because of the easiness to perform and tolerable postoperative outcome. Among the various local flaps, the authors introduce V-M plasty for correction of web space contracture and syndactyly. Method: From March 2007 to Jun 2008, 4 patients underwent V-M plasty for correction of web space contracture and syndactyly. V-M plasty consists of 3 distinct triangular flaps. One triangular flap is designed next to the web region on the dorsal site of the hand, whereas the remaining 2 triangular flaps are placed on the volar site. The dorsal triangular flap is then placed between the volar adjacent triangular flaps. At the end of the operation, the involved fingers or toes are positioned in abduction to avoid kinking of the triangular flaps. Result: All the patients gained web functions with good esthetic appearance without any recurrence or complications. Mean follow-up was 8 months. Conclusion: V-M plasty is a safe, easy and rapid procedure to design and apply by using local tissues without the needs for a skin graft or risk of linear scarring and recurrence. The authors advise this versatile technique both in primary and recurrent cases of web space contracture and syndactyly.
