Objective : This study was carried out to review Chang-Won Lee's theory of Sasangand acupuncture of constitution. Methods : We have investigated Chang-Won Lee's unknown literature "Medicine of sassang "(四象醫學). Results : Constitutional acupuncture is based on the diversity of human being and medically developed the response variation to disease and acupuncture. The diversity is due to the Organ's Congenital Formation Variation based on human nature and it is categorized as four from physiology, pathology, symptoms, to therapy. Chang-Won Lee's constitutional acupuncture discriminated constitution of comparison palpations of right and left both sides. He insisted that constitution only four type(Sasang), not exist man of To-Hyoung (土形人) in "young -chu"(靈樞) and his constitutional acupuncture all used Jung-kyuck (reinforcement acupuncture method) and Seong-kyuck(reducing acupuncture method) of Sa-am(舍岩)

In teleost, vitellogenin (Vtg) is synthesised in the liver in response to estrogens and transported by the blood to the growing oocytes where it is incorporated by micropincytosis (Selman and Wallace, 1982). Generally, Vtg is not induced in normal male fish but male fish are capable of synthesis Vtg in reponse to exogenous estrogen and xenoestrogens. (omitted)

Objectives : The purpose of this study was to evaluate Oriental Medicine Therapy on the Lumbosacral plexitis patient. Methods : The patient was treated with dry needle acupuncture, bee venom pharmacupuncture, herb medicine, indirect moxibustion and physical therapy. We estimated S kinds of Symptoms by Visual Analog Scale, lower limb motor grade test, gait condition test and sensory examination to evaluate the effect of Oriental conservative treatment. Results : After treatment, patient's visual analogue scale score were generally decreased 10 to 4 and lower limb muscle power and gait condition were improved. Conclusions : Oriental Medicine Therapy might be an effective method to treat the Lumbosacral plexitis patient who was diagnosed as Wei Symptom. It is necessary to have more observation and many cases of patients with Lumbosacral plexitis.

This paper proposes the method to predict the wind turbine power generation using logic-based fuzzy neural networks. To predict the wind turbine power generation neural networks, logic-based fuzzy neural networks, and fuzzy neural models have been considered. But the model considered in this paper can predict the wind turbine power generation with a less complex structure. The simulation results show the effectiveness of the proposed method.

This study examined from "SangHanChangHwaHunJiJip" how medical exchange between doctors of Joseon and Japan affected medical science of Japan. "SangHanChangHwaHunJiJip" is a record that organized the written conversation between doctors and scholars of the Joseon and Edo period when the delegation so-called Joseon Tongsinsa visited Japan in 1719. Even though "SangHanChangHwaHunJiJip" was written by Japanese, but it was comprised of Joseon's advanced medical ideology, especially "DongEuiBogam" that has occupied an important part of the Joseon medical ideology. As a matter of fact, "SangHanChang HwaHunJiJip" contains general theme and medical subject. But until now, it has been hardly studied by medical historians. Many studies were generally made related to Joseon Tongsinsa, a governmental delegation, focused on literary and cultural exchange between Joseon and Japan by historians. "SangHanChangHwaHunJiJip" is no exception to this trend. We can find that doctors of the Joseon and Edo period entered into colloquium, a form of group discussion, about the clinical theme in "SangHanChangHwaHunJiJip". Concretely, the conversation between doctors of Joseon and Japan was about infant disease, infectious disease, folk remedies, medical herbs, moxa cautery, acupuncture, the study of nature, the study of medical books, etc. For example, when doctors of Japan ask a confirmed disease, doctors of Joseon explained it particularly. They had a great effect on in every cultural aspect of Japan, especially its medical field. Through this study of the medical questions and answers in "SangHanChangHwaHunJiJip", I came to know that the doctors of GiHae envoys gave great influence to the medical knowledge of Japan and the GiHae inherited and developed the medical tradition of SinMyo envoys. Through the examination of this study, I could deduct that "JeongJeongDongEuiBogam" which was published by the government of the Edo period is due to not only the contents of DongEuiBogam's advanced medical thought, but also the doctors of GiHae envoy. Also, "SangHanChangHwaHunJiJip" gives us an idea that doctors of GiHae envoys have medical trend of the OnBoHakFa and a group of Japanese doctors has medical trend of the study of nature. I am confident that the improvement of medical science and natural history of the Edo period is due to influence of medical exchange between Joseon and Japan. "SangHanChangHwaHunJiJip" confirms that medical exchange between two countries affected doctors and scholars of the Edo period.

Objectives: The purpose of the present study was to evaluate the preventive effects of ethanol extract of Polygalae radix (EEPR) against oxidative stress (hydrogen peroxide, $H_2O_2$)-induced DNA damage and apoptosis in Chang liver cells. Methods: Chang liver cells were pretreated with various concentrations of EEPR and then challenged with 0.5 mM $H_2O_2$. The cell viability and apoptosis were assessed using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay and flow cytometry analysis, respectively. The levels of reactive oxygen species (ROS), mitochondrial membrane potentials (MMPs) and adenosine tri-phosphate (ATP) contents were measured. Expression levels of Bcl-2 and Bax were also determined using Western blot analysis. Results: The results showed that the decreased survival rate induced by $H_2O_2$ could be attributed to the induction of DNA damage and apoptosis accompanied by the increased production of ROS, which was remarkably protected by EEPR. In addition, the loss of $H_2O_2$-induced MMPs and ATP contents was significantly attenuated in the presence of EEPR. The inhibitory effect of EEPR on $H_2O_2$-induced apoptosis was associated with up-regulation of Bcl-2 and down-regulation of Bax, thus reducing the Bax/Bcl-2 ratio. Conclusions: Our data prove that EEPR protects Chang liver cells against $H_2O_2$-induced DNA damage and apoptosis by scavenging ROS and thus suppressing the mitochondrial-dependent apoptosis pathway.
