Purpose: The external ear is a common area of trauma on the body prone to exposure of ultraviolet light, which can lead to skin cancer. Thus, variable techniques have been developed and used for reconstruction of the external ear. The aim of this study is to review the surgical method, its area of application, as well as advantages and pitfalls of reconstruction of the external ear with inferior based retroauricular flaps. Materials and Methods: Eight patients underwent external ear reconstruction with inferior based retroauricular flap for external ear defects in our institute from September 2012 to June 2015. According to the area of the defect, patients were classified as middle 1/3 (n=4), inferior 1/3 (n=2), superior auroculo-cephalic sulcus (n=1), and external auditory canal (n=1). Results: All of the flaps survived the operation and there was no marginal necrosis. Mean size of the defect was $2.8{\times}1.8cm$ and mean size of the retroauricular flap was $5{\times}2cm$. For insetting of the flap, a subcutaneous tunneling technique was used in 6 cases and rotation without subcutaneous tunneling was used in 2 cases. Transient paresthesia occurred in 3 cases. Two cases recovered within 3 months but one case did not recover until 6 months. Conclusion: The inferior based retroauricular flap is an available technique in external ear reconstruction with one stage operation.

Purpose: The goal of this study was to see how different aerobic exercise intensities affected AMP-activated protein kinase (AMPK), reactive oxygen, and antioxidant enzymes in young mice during an 8-week period. Methods: Forty male C57BL/6 mice, aged seven weeks, were randomly assigned to one of four groups: control (n=10), low-intensity exercise (n=10), moderate-intensity exercise (n=10), and high-intensity exercise (n=10). For eight weeks, aerobic activity was performed once a day for 35-40 minutes, five days a week. The data were analyzed using descriptive statistics, analysis of variance (ANOVA), chi-squared tests, and the Tukey test in the SPSS/WIN 25.0 program. Results: Weight (p=.001) was substantially different between the moderate-intensity exercise group and the control group in AMPK (p<.001). In addition, there were no significant differences between the moderate-intensity exercise group and the control group in reactive oxygen malondialdehyde (MDA) levels (p=.136) and antioxidant enzyme superoxide dismutase (SOD) levels (p=.521). Conclusion: These findings suggest that moderate-intensity aerobic exercise increased AMPK activation and helped young mice shed weight.

[Purpose] This study compared differences in trabecular bone architecture and strength caused by jump and running exercises in rats. [Methods] Ten-week-old male Wistar rats (n=45) were randomly assigned to three body weight-matched groups: a sedentary control group (CON, n=15); a treadmill running group (RUN, n=15); and a jump exercise group (JUM, n=15). Treadmill running was performed at 25 m/min without inclination, 1 h/day, 5 days/week for 8 weeks. The jump exercise protocol comprised 10 jumps/day, 5 days/week for 8 weeks, with a jump height of 40 cm. We used microcomputed tomography to assess microarchitecture, mineralization density, and fracture load as predicted by finite element analysis (FEA) at the distal femoral metaphysis. [Results] Both jump and running exercises produced significantly higher trabecular bone mass, thickness, number, and fracture load compared to the sedentary control group. The jump and running exercises, however, showed different results in terms of the structural characteristics of trabecular bone. Jump exercises enhanced trabecular bone mass by thickening the trabeculae, while running exercises did so by increasing the trabecular number. FEA-estimated fracture load did not differ significantly between the exercise groups. [Conclusion] This study elucidated the differential effects of jump and running exercise on trabecular bone architecture in rats. The different structural changes in the trabecular bone, however, had no significant impact on trabecular bone strength.

BACKGROUND/OBJECTIVES: Obesity is a major risk factor for metabolic syndrome, a global public health problem. Mentha canadensis (MA), a traditional phytomedicine and dietary herb used for centuries, was the focus of this study to investigate its effects on obesity. MATERIALS/METHODS: Thirty-five male C57BL/6J mice were randomly divided into 2 groups and fed either a normal diet (ND, n = 10) or a high-fat diet (HFD, n = 25) for 4 weeks to induce obesity. After the obesity induction period, the HFD-fed mice were randomly separated into 2 groups: one group continued to be fed HFD (n = 15, HFD group), while the other group was fed HFD with 1.5% (w/w) MA ethanol extract (n = 10, MA group) for 13 weeks. RESULTS: The results showed that body and white adipose tissue (WAT) weights were significantly decreased in the MA-supplemented group compared to the HFD group. Additionally, MA supplementation enhanced energy expenditure, leading to improvements in plasma lipids, cytokines, hepatic steatosis, and fecal lipids. Furthermore, MA supplementation regulated lipid-metabolism-related enzyme activity and gene expression, thereby suppressing lipid accumulation in the WAT and liver. CONCLUSIONS: These findings indicate that MA has the potential to improve diet-induced obesity and its associated complications, including adiposity, dyslipidemia, hepatic steatosis, and inflammation.

본 연구에서는 진피-황금 혼합물 (CS)이 급성 역류성 식도염에 미치는 식도 점막 보호 효과를 평가하기 위하여 CS를 경구투여한 후 수술을 통해 역류성 식도염을 유발하였으며, 실험 종료 후 혈액 채취 및 식도 조직을 적출하였다. 동물에게서 적출한 식도 점막의 손상 정도를 육안으로 확인한 결과 CS투여군에서 식도 점막의 손상이 유의하게 감소하였으며, H&E staining을 통해 관찰한 결과 마찬가지로 CS투여군에서 식도 상피의 탈락 및 염증세포의 침윤이 현저하게 감소한 것을 확인하였다. 혈액을 이용하여 역류성 식도염의 원인으로 유효하다고 알려진 ROS의 수치를 확인한 결과, CS투여군에서 ROS 수치가 유의적으로 감소하였으며, western blotting을 통해 NADPH oxidase인 NOX4, p47^phox, p22^phox의 발현을 확인한 결과, 마찬가지로 CS 투여군에서 유의하게 감소하였고, 특히 CS200투여군에서 Normal군과 비슷한 수치를 나타냈다. 또한, CS투여는 염증성 단백질인 MAPK와 NF-κB 경로를 유의적으로 억제하였을 뿐 아니라 tight junction 단백질인 claudin-1과 claudin-4의 발현을 유의하게 조절한 것을 확인하였다. 이상의 결과를 종합해보면 진피-황금 추출물은 산화적 스트레스를 억제함으로써 염증성 단백질의 발현을 조절할 뿐 아니라 tight junction 단백질의 발현을 조절하여 식도 점막을 보호하는 것으로 판단되나 역류성 식도염은 음식물의 섭취와 밀접한 관련이 있는 만큼 추후 동물의 식이 섭취량을 조사하는 등 세부적인 추가 연구가 필요할 것으로 보인다.
