Taraxacum coreanum Nakai (TM) has been investigated for its antidiabetic activity in streptozotocin induced diabetic animals, but few studies have been conducted to evaluate its efficacy for treatment of type II diabetic mice. This study was designed to evaluate the efficacy of the water extracts of TM for the treatment of type II diabetes. Twenty four mice(C57BLKS/J Iar -+Lepr db /+Lepr db ) with type II diabetes were randomly assigned either to a experimental group A (leaves extraction of TM), experimental group B(roots extraction of TM), experimental group C(leaves, roots and flowers extraction of TM) or control group. Water extracts of TM were ingested for 10 weeks. The changes of body weight, level of blood glucose, numerical change of insulin-immunoreactive cells and level of blood insulin were measured after treatment of water extracts of TM. A reduction of the blood glucose level after treatment of TM was observed in all the experimental groups. Especially, experimental C group showed significant reduction of blood glucose level compared with control group. Experimental C group induced an increase the level of blood insulin and density of insulin immunoreactive cells after treatment of TM. These results show that water extracts of TM can improve the severity in type II diabetic mice.
The purpose of this morphological studies was to investigate the relation between the meridian, acupoints and viscera using neuroanatomical tracers. The common locations of the spinal ganglia, sympathetic chain ganglia, spinal cord and brain projecting to the large intestine meridian were observed following injection of transganglionic tracer, WGA-HRP and transsynaptic neurotropic virus, pseudorabies virus(PRV), Bartha strain(Ba) and PRV-Ba-Gal (Galactosidase)) into the the large intestine(cecum, colon and rectum), ST37 and LI4. After survival times of 96 hours following injection into the thirty rats with WGA-HRP, PRV-Ba and PRV-Ba-Gal. They were perfused, and their spinal ganglia, sympathetic chain ganglia, spinal cord and brain were frozen sectioned(30㎛). These sections were stained by HRP and X-gal histochemical and PRV immunohistochemical staining method, and observed with a light microscope. The results were as follows : 1. WGA-HRP labeled neurons innervating the large intestine were observed bilaterally within the T13-L4 sympathetic chain ganglia, and T9-11 spinal ganglia. WGA-HRP labeled neurons innervating ST37 were observed within the L3-5 sympathetic chain ganglia, and L2-4 spinal ganglia. WGA-HRP labeled neurons innervating LI4 were observed in the middle cervical ganglion and stellate ganglion, and C5-8 spinal ganglia. 2. In spinal cord, PRV-Ba labeled neurons projecting to the large intestine, ST37 and LI4 were found in thoracic, lumbar and sacral spinal segments. Densely labeled areas of each spinal cord segment were founded in lamina N, V, VII(intermediolateral nucleus), IX, X and dorsal nucleus. 3. In medulla oblongata, PRV-Ba and PRV-Ba-Gal labeled neurons projecting to the large intestine, ST37 and LI4 were commonly found in the A1 noradrenalin cells/C1 adrenalin cells/caudoventrolateral reticular nucleus, dorsal motor nucleus of vagus nerve, nucleus tractus solitarius, raphe obscurus nucleus, raphe pallidus nucleus, raphe magnus nucleus and gigantocellular nucleus. 4. In pons, PRV-Ba and PRV-Ba-Gal labeled neurons were commonly found in locus coeruleus, Kolliker-Fuse nucieus and A5 cell group. 5. In midbrain, PRV-Ba and PRV-Ba-Gal labeled neurons were commonly found in central gray matter. 6. In diencephalon, PRV-Ba and PRV-Ba-Gal labeled neurons were commonly found in paraventricular hypothalamic nucleus. These results suggest that PRV-Ba and PRV-Ba-Gal labeled common areas projecting to the large intestine may be correlated to that of the large intestine meridian, ST37 and LI4. Especially, These morphological results provide that interrelationship of meridian-acupoints -viscera may be related to the central autonomic pathways.
본 논문에서는 서식 문서의 선과 숫자의 획이 접촉된 경우 숫자의 획을 접촉되기 전 상태의 원 이미지로 복원하는 방법을 제안한다. 제안하는 방법은 서식 문서에서 추출한 숫자열을 대상으로 열 단위로 복원한다. 과정은 우선 숫자열과 접촉된 선의 위치를 찾아내고, 선을 추적하면서 접촉으로 판정되는 영역을 유형별로 분류하여, 각 유형에 적합한 획 복원 방법을 제안한다. 또한 선에 숫자의 획이 완전히 포함된 경우의 복원 방법도 제안하여 현장에서의 서식 처리 과정에서 발생하는 문제점을 해결하고자 하였다. 제안하는 방법을 평가하기 위해서 은행 입출금전표, 신용카드 매출전표 및 NIST 필기 숫자열 데이타베이스 이미지를 사용하였다.
Perfluorinated sulfonic acid (PFSA) ionomers have been used as representative membrane materials in a wide range of applications such as fuel cells, electrolysis, and redox flow batteries.Though PFSA ionomers have been well known as chemically durable materials, their tolerance should be improved further for applying them to practical fuel cell systems operated under harsh conditions. One plausible solution to this issue would be to impregnate PFSA ionomers in microporouspoly (tetrafluoroethylene) (PTFE) support films employing pore-filling mem braneconcept. Fundamental characteristics of the resulting PFSA-PTFE membranes are highly influenced by material factors as well as processing variables. In this study, PTFE support films with different physical characteristics are utilized to prepare PFSA pore-filling membranes and investigate their membrane properties.
The aim of this study was to systemically develop indicators of performance evaluation for elite athletics and coaches in Goyang-si Athletic Departments. We collected documents such as athletics and coaches’ outcomes of performances and interviewed with administrators, athletics and coaches to know currents situations of performance evaluation in Goyang-si Athletics Departments. And then, we built a direction of a new performance evaluation. Based on these resources and analysis, we developed new performance evaluation in terms of a quantitative and qualitative approach. Finally, we proposed to develop many studies of performance evaluation in respect of characteristic of each local government. These studies would be helpful references to make new performance evaluation in Athletics Departments of local government.
