  • Background Financial, clinical, and psychological considerations have made same-day surgery an attractive option for a variety of procedures. This article aimed to analyse the postoperative results of same-day primary unilateral cleft nasolabial repair. Methods This study was performed from 2011 to 2014. Unilateral cleft lip patients fulfilling the inclusion criteria were preoperatively classified as mild, moderate, and severe. All patients underwent same-day surgery and were discharged after satisfying the appropriate clinical criteria, receiving thorough counselling, and the establishment of a means of communication by phone. Postoperative outcomes were assessed and stratified according to preoperative severity and the type of repair. Results A total of 423 primary unilateral cleft lip patients were included. Fisher's anatomical subunit approximation technique was the most common procedure, followed by Noordhoff's technique. The postoperative outcome was good in 89.8% of cases, fair in 9.9% of cases, and poor in 0.2% of cases. The complication rate was 1.18% (n=5), and no instances of mortality were observed. The average hospital stay was 7.5 hours, leading to a cost reduction of 19% in comparison with patients who stayed overnight for observation. Conclusions Mild unilateral cleft lip was the most common deformity for which Fisher's anatomical subunit approximation technique was performed in most of the cases, with satisfactory postoperative outcomes. Refinements in the cleft rhinoplasty techniques over the course of the study improved the results regarding cleft nasal symmetry. Single-day primary unilateral cleft cheiloplasty was found to be a cost-effective procedure that did not pose an additional risk of complications.

  • Objective : This study was carried to identify the anatomical component of FTMM(Foot Taeyang Meridian Muscle) in human lower limb, and further to help the accurate application to real acupuncture. Methods : FTM at the surface of the lower limb was labelled with latex. And cadaver was stripped off to demonstrate muscles, nerves and the others and to display the internal structures of FTMM, being divided into outer, middle, and inner layer. Results : FTMM in human lower limb is composed of muscles, nerves, ligaments etc. The internal composition of the FTMM in human lower limb are as follows : 1) Muscle : Gluteus maximus. biceps femoris, semitendinosus, gastrocnemius, triceps calf, fibularis brevis tendon, superior peroneal retinacula, calcaneofibular ligament, inferior extensor retinaculum, abductor digiti minimi, sheath of flexor tendon at outer layer, biceps femoris, semimembranosus, plantaris, soleus, posterior tibialis, fibularis brevis, extensor digitorum brevis, flexor digiti minimi at middle layer, and for the last time semimembranosus, adductor magnus, plantaris, popliteus, posterior tibialis, flexor hallucis longus, dorsal calcaneocuboidal ligament at inner layer. 2) Nerve : Inferior cluneal nerve, posterior femoral cutaneous n., sural cutaneous n., proper plantar branch of lateral plantar n. at outer layer, sciatic nerve, common peroneal n., medial sural cutaneous n., tibial n. at middle layer, and for the last time tibial nerve, flexor hallucis longus branch of tibial n. at inner layer. Conclusions : This study proves comparative differences from already established studies from the viewpoint of constituent elements of FTMM in the lower limb, and also in the aspect of substantial assay method. We can guess that there are conceptional differences between terms (that is, nerves which control muscles of FTMM and those which pass near by FTMM) in human anatomy.

  • 국산 침 활엽수재의 열분해 및 해부학적 특성에 관해 조사하기 위해 침엽수재 3종(소나무, 리기다소나무, 낙엽송) 및 활엽수재 3종(단풍나무, 물푸레나무, 굴참나무)의 화학적 성분분석, TG-DTA (Thermogravimetric Analysis & Differential Thermal Analysis), 메틸렌블루 흡착성능(MBA) 및 SEM 관찰을 하였다. TG-DTA에서 시료는 $1{\ell}/min$$N_2$ 가스가 유입되는 조건하에 $10^{\circ}C$/min의 숭온속도로 최대 $10^{\circ}C$까지 탄화되었다. 화학적 성분분석 결과 모든 시료에서 전형적인 목재 주성분의 함량을 나타냈다. TG-DTA 결과, 침엽수재의 탄화수율이 활엽수보다 높았으며 목재 주성분 중 리그닌의 탄화수율이 가장 높았다. 모든 시료가 전형적인 목재 열분해의 TGA, DTG, DTA 곡선을 나타냈지만, 침 활엽수재 간에 몇 가지 차이점이 나타났다. 리그닌의 함량이 열분해에 큰 영향을 미쳤으며, 리그닌의 분자구조에 따라 중량감소와 탄화수율이 크게 달라졌다. 메틸렌블루 흡착성능 시험 결과 침엽수재의 MBA가 활엽수재보다 높았으며 소나무의 MBA가 가장 높았지만, 활성탄이나 백탄보다는 약 23배, 4씩 낮았다. SEM 관찰 결과 탄화 과정에서 전체적인 목재의 구조와 목재 섬유의 섬유구조가 그대로 유지됨을 확인하였다.

  • This study examined the anatomical relationships along with the variability of the facial nerve trunk and its branches with an emphasis on the intraparotid connections between the divisions. And histomorphometric observations of the facial nerve branches and fascicles were performed on 40 Korean half-heads. The facial nerve trunk was bifurcated into two main divisions(35/40, 87.5%) and the other five cases were divided into a trifurcation pattern. According to the origin of the buccal branch, the branching patterns of the facia l nerve were classified into four categories. Communications between the facial and auriculotemporal nerve branches were observed in 37 out of 40 cases(92.5%). In the histological observation, the buccal branch had the greatest number of branches(3.47), however the zygomatic branch had the largest diameters(0.93mm). This detailed description of the facial nerve anatomy wi ll provide useful information for surgical procedures such as a tumor resection. a facial nerve reconstruction, autonerve graft. and facelift.

  • In order to promote scientification of Korean medicine, two hypothetical scenarios were proposed methodologically. Firstly, the scientification of Korean medicine requires a comprehensive understanding of the process and reality, and new logical procedures and the methods of observation and experiment. Secondly, transformation to revised Korean medicine is to replace traditional Korean medicine with biochemistry-based Western medicine, that is a method of reconstructing the recognition foundation describing symptoms and diseases using anatomical platforms and analytical tools. But there are areas of human training and practice that are not subject to scientification, and there are incommensurable parts as for the methodology between western medicine too. And additionally arbitrary rejection by uniform science with a political reason was done. So these various backgrounds and factors should be considered for the scientification of Korean medicine. And before that, reflection and agreement on the understanding and attitude of the method of scientification within the Korean medical community is necessary.

  • Detailed structures of ectomycorrhizae formed in Pinus roots were observed with various microscopes: light, fluorescence, and scanning electron microscopes. The mantles and Hartig nets commonly found in the structure of ectomycorrhiza were newly observed according to developmental stage by various staining. The mycelia were observed to be composed of coiled types on the surface of epidermal root during early stage and fused to form mantles of smooth fungal layers, loosing mycelia with some viscous liquid secreted. The ectomycorrhizal hyphae in anatomical roots penetrated the cortical layer and formed obviously mantle and Hartig net. The round spots of ectomycorrhizal mycelia were observed morphological distribution from the cortical layer to vascular bundle of stele in the ectomycorrhizal roots of Pinus species and especially scattered at the area of meristem at the root tip as longitudinal sections. Those mycelia penetrated seemed to move into other roots by means of vascular bundle of ectomycorrhizal roots and newly form ectomycorrhizal roots of dichotomous branches.

  • The effects of salicylic acid(SA) and water deficit on growth and proline accumulation were investigated in cucumber(Cucurmis sativus L.) seedlings. Exogenous application of SA(100 $\mu$M-1 mM) led to a noticeable decrease in root and shoot growth, and dry weight of seedlings. Anatomical observation on leaf of cucumber revealed that the thickness of all leaf tissue components decreased in SA-treated plants. The effect was most pronounced on the width of the adaxial epidermis. In the separate effects of SA(0, 100, 500 and 1000 $\mu$M) and water deficit induced by PEG(0, 4.4, 7.0 and 9.6 %) on growth, the water deficit treatments had greater effects on growth traits than SA. Combinations of SA and PEG(SA+PEG) decreased shoot and root dry matter, and root length. Proline increased slightly in SA-treated seedlings, but exhibited a marked increase in water deficit application. Combinations of SA+PEG induced higher proline in both shoots and roots than SA stress alone. Shoots had higher proline than roots. Our data support a role of SA potentiating the osmotic stress response of germinating cucumber seedling.
