The modern education institutes play an important role in fostering professional talents, reproducing knowledge and studies, and forming the identities of certain academic fields and vocational communities. It is a matter of common knowledge that the absence of an official Korean medicine medical school during the Japanese colonial era was a severely disadvantageous factor in the aspects of academic progress, fostering follow-up personnel, and establishment of social capability. Therefore, the then Korean medicine circle put emphasis on inadequate official education institutes as the main factor behind oppression. Furthermore, as the measure to promote the continuance of Korean medicine, the circle regarded establishing civilian Korean medicine training schools as their long-cherished wish and strived to accomplish the mission even after liberation. This study looked into how the Korean medicine circle during the Japanese colonial era utilized civilian training schools to conduct the Korean medicine education conforming to modern medical school and examined how the operation of these training schools influenced the changes in the traditional Korean medicine. After the introduction of the Western medical science, the Korean medicine circle aimed to improve the quality of Korean medicine doctors by establishing modern Korean medicine medical schools. However, after the annexation of Korea and Japan, official Korean medicine medical schools were not established since policies were organized centered on the Western medical science. In this light, the Korean medicine circle strived to nurture the younger generation of Korean medicine by establishing and operating the civilian Korean medicine training schools after the annexation between Korea and Japan. The schools were limited in terms of scale and status but possessed the forms conforming to the modern medical schools in terms of education system. In other words, the civilian training schools not only adhered to the standard education of Korean medicine but also aimed to lay their foundation in the education system of the Western medical science by forming the separated curriculum including basic medical science, diagnosis, clinic, drug, and the practice of acupuncture and moxibustion. Furthermore, having contained the basic subjects of the Western medical science - physiology, anatomy, pathology, etc. - in the compulsory subjects shows perceiving the intellectual and systematic hegemony of the Western medical science and satisfying the demand of the colonial power. Such an education system was succeeded and solidified through the training sessions and the training schools operated by the local colonial governments after the 1930s. Korean medicine became different from the traditional Korean medicine through the establishment and the operation of such training schools.

The effects of Panax notoginsen saponins ( PNGS ) on myocar- dial ischemia and reperfusion injury in conscious rabbit were studied with observation of changes in electrocardiogram (ECG), the activities of creatine phosphokinase ( CPK ) and lactate dehydrogen-ase ( LD ) and the size of ischemic area. 50 mg/kg and 100 mg/kg PNGS significantly decreased the activities of CPK and LD, and the abnormal changes of ECG during ischemic and reperfusion periods. Also, PNGS significantly reduced the size of myocardial ischemic area. These results suggest that PNGS have the protective effects on myocardial ischemia and reperfusion injury.

Rabies prevention has become a vital part of public health administration owing to the high incidence of rabies in Japan in modern times. The rabies prevention system in Japan, which was gradually established based on the rabies knowledge and prevention policies from Europe and the United States, was centered on livestock dog control, wild dog culling, and vaccination. This epidemic prevention system was based on two premises. First, though rabies is a zoonotic infectious disease, the focus of epidemic prevention administration was to protect humans, not dogs. Second, this system attempted to eliminate the rabies hazard at its source by reducing the number of all dogs—livestock dogs included. Under this epidemic prevention mechanism, the survival space of dogs as an object of public health administration was significantly eroded. In contrast, during wartime, the Japanese Empire encouraged people to donate their dogs to the military so their fur could be used to make military coats, and in the name of existing rabies prevention programs, extended the target of culling from wild dogs only to all non-military dogs. This administrative model of epidemic prevention, which attempted to hide the violence and arbitrariness of dog killing by creating artificial distinctions among dogs, is a metaphor for the power training mechanism in modern society.

Vascular smooth muscle cell (VSMC) migration plays a critical role in the pathogenesis of many cardiovascular diseases. We recently showed that TMEM16A is involved in hypertension-induced cerebrovascular remodeling. However, it is unclear whether this effect is related to the regulation of VSMC migration. Here, we investigated whether and how TMEM16A contributes to migration in basilar artery smooth muscle cells (BASMCs). We observed that AngII increased the migration of cultured BASMCs, which was markedly inhibited by overexpression of TMEM16A. TMEM16A overexpression inhibited AngII-induced RhoA/ROCK2 activation, and myosin light chain phosphatase (MLCP) and myosin light chain (MLC20) phosphorylation. But AngII-induced myosin light chain kinase (MLCK) activation was not affected by TMEM16A. Furthermore, a suppressed activation of integrin
