Acupuncture has been clinically used to treat patients suffering from eye disease. It has been used in efforts to help preserve vision for those with a wide range of eye conditions including glaucoma and intraocular hypertension. High intraocular pressure (IOP) is usually associated with glaucoma and conventional treatment is focused on lowering IOP. Controlling this risk factor should help hasten the onset of glaucoma for those patents that are suspect or borderline candidates for glaucoma. In review of the limited scientific research there are not many studies that support conclusive evidence for the use of acupuncture on eye diseases and particularly glaucoma and ocular hypertension. For the information that does exist, diverse results from various interventions make it difficult to draw clear conclusions. The existing studies use different acupoints, techniques, frequencies, and durations. Individual treatment strategies according to the practitioner's subjective experience, patient condition, and the use of other complimentary and natural strategies is ideal for taking a more dynamic and wholistic approach to getting results. Until more pragmatic research models are funded and implemented, case reports can offer good examples of experiential and objective outcomes. This case report presents a 61 year old healthy female patient diagnosed with open-angle borderline glaucoma with elevated IOP. The patients IOP was successfully reduced with 12 treatments over three months using scalp electro-acupuncture and distal Master Tung points.

Dysfunction of the anterior and dorsal muscles of the trunk have been studied in relation to low back pain of many years. Many muscles of the trunk are capable of contributing to the stabilization and protection of the lumbar spine, recent evidence has suggested that transversus abdominis may be critically involved and has been the focus of rehabilitation. The delay in onset of contraction of trunk muscles associated with movement of the upper or lower limb in patients with low back pain indicates a significant deficit in the automatic motor command for control of disturbance to the spine. The function of transversus abdominis has been largely ignored in the evaluation of spinal stabilization and protection. The most essential stabilizing muscles for the lumbar column are the transversus abdominis and the multifidus. Sling exercise therapy(SET) concept consists of a system of diagnosis and treatment. The system of diagnosis involves testing the muscle's tolerance through progressive loading in open and close kinetic chains. The SET system contains elements such as relaxation, increasing the range of movement, traction, training the stabilizing musculature, sensorimotor exercises, training in open and close kinetic chains, dynamic training of the mobilizing musculature, cardiovasc+ular exercises, group exercise, personal exercise at home. Sensorimotor training is an essential element of the SET concept. The emphasis is on closed kinetic chain exercises on an unstable surface, thereby achieving optimum stimulation of the sensorimotor apparatus.

The native extracellular matrix (ECM) consists of an integrated fibrous protein network and proteoglycan-based ground (hydrogel) substance. We designed a novel electrospinning technique to engineer a three dimensional fiber-hydrogel composite that mimics the native ECM structure, is injectable, and has practical macroscale dimensions for clinically relevant tissue defects. In a model system of articular cartilage tissue engineering, the fiber-hydrogel composites enhanced the biological response of adult stem cells, with dynamic mechanical stimulation resulting in near native levels of extracellular matrix. This technology platform was expanded through structural and biochemical modification of the fibers including hydrophilic fibers containing chondroitin sulfate, a significant component of endogenous tissues, and hydrophobic fibers containing ECM microparticles.

This paper compares OECD nations by developing a comprehensive evaluation index that examines the efforts and achievements of countries toward Low-Carbon Green Growth. The input-process-output of a Low-Carbon Society system is in dynamic competition with that of a High-Carbon Society system. The model used in this study of the comprehensive evaluation index for Low-Carbon Green Growth was comprised of Large indices such as Input, Process, and Output. The Input and Output consisted of 'Social-economic' and 'Physical-ecological' Middle indices while the Process was made up of 'Stimulation mechanisms' and 'Participation of stakeholders and Knowledge flow' Middle indices. In order to calculate the comprehensive evaluation index, our model gave a weight to each indicator/index and applied a weighted arithmetic mean. Korea ranked $15^{th}$ out of 30 OECD nations in the comprehensive evaluation that analyzed Input ($14^{th}$), Process ($18^{th}$), and Output ($17^{th}$). The top five nations were Switzerland, Sweden, Denmark, Germany, and France; while Japan was $8^{th}$ and the USA $26^{th}$.

The present study was designed to examine whether the co-application of morphine with $Ca^{2+}$ channel antagonist $(Mn^{2+},\;verapamil)$, N-methyl-D-aspartate (NMDA) receptor antagonist (2-amino-5-phosphonopentanoic acid$[AP_5]$, $Mg^{2+}$) or protein kinase C inhibitor (H-7) causes the potentiation of morphine-induced antinociceptive action by using an in vivo electrophysiological technique. A single iontophoretic application of morphine or an antagonist alone induced weak inhibition of wide dynamic range (WDR) cell responses to iontophoretically applied NMDA and C-fiber stimulation. Although there was a little difference in the potentiating effects, the antinociceptive action of morphine was potentiated when morphine was iontophoretically applied together with $Mn^{2+}$, verapamil, $AP_5$, $Mg^{2+}$ or H-7. However, the potentiating action between morphine and each antagonist was not apparent, when the antinociceptive action evoked by morphine or the antagonist alone was too strong. These results suggest that the potentiating effect can be caused by the interaction between morphine and each antagonist in the spinal dorsal horn.

Effect of clonidine on the dorsal horn cell responses to mechanical stimulations were studies in 3 spinalized cats and 10 cats with intact spinal cord. The type of dorsal horn cells was determined according to their response patterns to four graded mechanical stimulations (brush, pressure, pinch and squeeze) applied to the respective receptive fields. In the present study the results obtained only from the wide dynamic range (WDR) cells were included. The responses of the WDR cells to noxious mechanical stimuli were selectively suppressed following intravenous administration of clonidine into the experimental animals. The clonidine-induced changes in responses of the WDR cells to mechanical stimulation were not affected by naloxone or propranolol whereas effect of clonidine on WDR cell responses was almost completely abolished after intravenous administration of yohimbine. Also in the spinalized cats results parallel to those observed in cats with intact spinal cord were obtained. The results of present study strongly implies that analgesic action of clonidine can be mediated through excitation of ${\alpha}_{2}-adrenoceptor$ even at the spinal cord level without supraspinal mechanism.

Objectives : This paper summarizes contents on fish in the Injeji and Jeoneo-Ji parts in the Imwon-Gyeongje-Ji and compares them with those in the Dong-uibogam from a Korean Medical perspective. Methods : Most of the knowledge of fish in the Imwon-Gyeongje-Ji is based on preceding material medica studies such as the Dongui-bogam in Joseon, the Bencao-gangmu in China, and the Hwahan Samjaedohoe in Japan. The influential relationships and the process of change among these knowledge information were examined within the context of each literature's development or through identifiable changes in knowledge on each particular kind of fish. Results & Conclusions : In the Imwon-Gyeongje-Ji, the consisting 16 parts are organically connected, sometimes functioning as cross-references. In particular, the medical contents on the efficacy of fish for treating disease is closely linked to contents on fish ecology and environment as written in the Jeoneo-Ji, which deals with the field of living things. On the more detailed knowledge on about 30 kinds of fish, one could grasp the formation process and changes of East Asian traditional knowledge on fishkind among historical study of influential Chinese texts, new stimulation and methodology through Japanese literature on natural history, and dynamic processes of inheriting and selectively accepting traditional knowledge of Joseon.

Wound healing is a complex and dynamic process, making the accurate and timely assessment of skin wounds a crucial aspect of effective wound care management, especially for chronic wounds. Unlike conventional wound dressings that simply cover the wound area once some form of medicine is administered onto the wound, recent studies have introduced versatile approaches to smart wound dressings capable of interacting with wound fluids to monitor physicochemical and pathological parameters to determine the wound healing status. Such electrochemical wound dressings can be integrated with on-demand, closed-loop drug delivery or stimulation systems and ultimately expanded into an ideal technological platform for the prevention, treatment, and management of skin wounds or illnesses. This article briefly reviews the wound healing mechanism and recent strategies for effective wound care management. Specifically, this review discusses the following aspects of smart wound dressings: sensor-integrated smart bandages to detect wound biomarkers, smart bandages developed to accelerate wound healing, and wireless, closed-loop automatic (on-demand) wound healing systems. This review concludes by providing future perspectives on effective wound care management.

The slow and regular pacemaking activity of midbrain dopamine (DA) neurons requires proper spatial organization of the excitable elements between the soma and dendritic compartments, but the somatodendritic organization is not clear. Here, we show that the dynamic interaction between the soma and multiple proximal dendritic compartments (PDCs) generates the slow pacemaking activity in DA neurons. In multipolar DA neurons, spontaneous action potentials (sAPs) consistently originate from the axon-bearing dendrite. However, when the axon initial segment was disabled, sAPs emerge randomly from various primary PDCs, indicating that multiple PDCs drive pacemaking. Ca²⁺ measurements and local stimulation/perturbation experiments suggest that the soma serves as a stably-oscillating inertial compartment, while multiple PDCs exhibit stochastic fluctuations and high excitability. Despite the stochastic and excitable nature of PDCs, their activities are balanced by the large centrally-connected inertial soma, resulting in the slow synchronized pacemaking rhythm. Furthermore, our electrophysiological experiments indicate that the soma and PDCs, with distinct characteristics, play different roles in glutamate-induced burst-pause firing patterns. Excitable PDCs mediate excitatory burst responses to glutamate, while the large inertial soma determines inhibitory pause responses to glutamate. Therefore, we could conclude that this somatodendritic organization serves as a common foundation for both pacemaker activity and evoked firing patterns in midbrain DA neurons.

A 25-year-old man with viral cardiomyopathy and chronic active hepatitis successfully underwent dynamic cardiomyoplasty for the first time in Korea on July 30, 1996. The patient had been intermittently dyspneic for 5 years and was admitted to our center twice because of heart failure. For the past 2 years, he was NYHA functional class III status with a left ventricular ejection fraction(LVEF) of around 30%. The patient was born with scoliosis and showed a short stature. The liver function showed elevated liver enzymes, and hepatitis B antigen was positive. The liver biopsy revealed chronic active hepatitis. The preoperative echocardiogram showed decreased left ventricular function with grade II mitral and grade II tricuspid regurgitation with dilated left and right atrium. Recently his symptoms worsened and we decided to perform a dynamic cardiomyoplasty. The left latissmus dorsi muscle(LDM) was mobilized and tested with lead placement on his right lateral decubitus position. The patient was positioned into supine and, after median sternotomy, the heart was wrapped with the mobilized muscle. The Russian made cardiomyostimulator(EKS-445) and leads (Myocardial PEMB for heart and PEMP-1 for LDM) were used. The total operation time was 8 hours and there were no perioperative episodes. Postoperatively the LDM had been trained for a 10 week period and currently the stimulation ratio is maintained at 1:4. The postoperative LVEF did not increase with the value of 30-35%. However, the patient feels better postoperatively with slightly increased activity.
