Objectives : The purpose of this paper is to investigate the mechanism of 'Joy impairs the Heart'. Methods : "Huangdineijing" was searched in relation to 'Joy' and 'Heart', then Joy was divided into physiological and pathological joy. After examination of the similarities and differences between the two, the mechanism of 'Joy impairs the Heart' was drawn out. Results : 1. Excessive Joy not only relaxes Qi(氣), but also disperses Shen(神). 2. Impairment of Heart damages heart locally and Impairment of Yang not only damages Qi or Shen focally, but also damages Yang of the whole body and the degree of damage is thought to be more extensive than "Joy impairs the Heart". 3. "Too much joy and pleasure can cause the Shen(神) to scatter and not remain stored." not only relaxes Qi, but also disperses Shen(神), and the degree of damage is less than "Sudden joy damages Yang". Conclusions : Excessive or Sudden Joy impairs the Heart by disturbing Heart's property of maintaining Taiyang by scattering Shen(神) or not maintaining high Yang density. Forced expression of Joy impairs the Heart by relaxing and stagnating Qi.

Human endogenous retroviruses (HERVs) were inserted into the human genome millions of years ago but they are currently inactive and non-infectious due to recombinations, deletions, and mutations after insertion into the host genome. Nonetheless, recent studies have shown that HERV-derived elements are actually involved in physiological phenomena and certain diseases including cancers. Among the various physiological phenomena related to HERV-derived elements, it is necessary to focus on inflammatory response. HERV-derived elements have been reported to be directly involved in various inflammatory diseases, including autoimmune diseases such as rheumatoid arthritis, multiple sclerosis, amyotrophic lateral sclerosis, and Sjogren's syndrome. As a mechanism for regulating inflammation through HERV-derived elements, the possibility that HERV-derived elements may cause nonspecific innate immune processes and that HERV-derived RNA or proteins may cause selective signaling mechanisms through specific receptors can be considered. However, the mechanism through which HERV-derived elements regulate inflammatory response, such as how silent HERV elements are activated in inflammatory response and what factors and signaling mechanisms are involved in HERV-derived elements, have not been identified to date, making it difficult to study the onset of HERV-related inflammatory disease. In this review, we introduce HERV-related autoimmune diseases and propose the mechanisms of HERV-derived elements at the molecular level of HERV in inflammatory response.

To find the cause, pathology, oriental presciptions for SLE(systemic lupus erythematous) in the field of oriental medicine, we studied the clinical reports. The results were obtained as follows: 1. SLE can' be thought to be a category of chronic fatigue, numbness, yang poison' & erythema. 2. The chief cause of SLE could be a febrile poison and the lack of physiological fluid and the mechanism was that febrile poison attacted area of circulation and blood and injuried the physiological fluid to arise edema and clotted blood. 3. The therapy of SLE was chiefly clarifying heat and toxiciding in acute stage while reinforcing kidney and liver and supplementing Yin & clarifying in chronic stage, sometimes supplementing Qi, eliminating clotted blood, excuding wind and draining water could be applied. 4. The therapy for SLE nephritis was shown to be increasing yin and clarifying heat with toxiciding, reinforcing spleen and kidney, draining water, supplementing yin & Qi etc. The chief prescriptions were Seogakjihwangtang(犀角地黃湯), Wookakjihwangtang(牛角地黃湯), yeechihwan(二至丸), Daepowonjeon(大補元煎), Daepoeumhwan(大補陰煎), Kikukjihwangtang(杞菊地黃湯), Yookmijihwangtang(六味地黃湯) which indicates Rhemanniae radix added prescrition could be used chiefly for the treatment of SLE.

Coenzyme $Q_{10}$ ($CoQ_{10}$) production from Rhizobium radiobacter T6102 was monitored under various oxygen supply conditions by controlling the agitation speeds, aeration rates, and dissolved oxygen levels. As the results, the $CoQ_{10}$ production was enhanced by limited oxygen supply. To investigate whether the $CoQ_{10}$ production is associated with its physiological functions of electron carrier and antioxidant, the effects of sodium azide and hydrogen peroxide on the $CoQ_{10}$ production were studied, showing that the $CoQ_{10}$ contents were slightly enhanced with increasing sodium azide (up to 0.4 mM) and hydrogen peroxide (up to $10\;{\mu}M$) concentrations. These results suggest the plausible mechanism where the limited electron transfer stimulating the environments of limited oxygen supply and oxidative stress could accumulate the $CoQ_{10}$, providing the relationship between the $CoQ_{10}$ physiological functions and its regulation system.

Recent advances in systems biology are shedding a new light on the traditional medicine research. The systems biology highlights the way each component interacts with each other within a system, and the network behavior that emerges from such interactions. This feature of systems biology can accent the systemic aspects of Korean medicine such as the mechanism of action of herbal formulae, pattern differentiation, and the meridian systems, as both the Korean medicine and the systems biology theorize the human physiological functions and phenomena from a holistic point of view. This paper outlines the meaning of the recent Korean medicine research using the systems biology methodology. We discuss the methodologies of the two fields in a comparative manner, and overview the advantages and limitations of the integrated approaches. Finally, we suggest the future prospects for the systems biology inspired approaches to the Korean medicine research. The systems biology may provide a new modernized research methodology for the Korean medicine that can highlight its unique features.

Two rice varieties, viz. Nonabokra and Pokkali, have been evaluated for their responses to salinity in terms of some physiological and biochemical attributes. During the exposure to salinity (200 mM concentration of sodium chloride for 24, 48, and 72 h), a significant increase in sodium was recorded which was also concomitant with the changes of other metabolic profiles like proline, phenol, polyamine, etc. The protein oxidation was significantly increased and also varied between the two cultivars. The changes in activities of anti-oxidative enzymes under stress were significantly different to the control. The detrimental effects of salinity were also evident in terms of lipid peroxidation, chlorophyll content, protein profiles, and generation of free radicals; and these were more pronounced in Pokkali than in Nonabokra. The assessment and analysis of these physiological characters under salinity could unravel the mechanism of salt responses revealed in this present study and thus might be useful for selection of tolerant plant types under the above conditions of salinity.

Ecophysiologically diapause represents a syndrome of physiological and biochemical characteristics, all of which ensure survival during a long period of dormancy. Since, silkworm enters diapause as embryo at the early embryonic stage, the duration of egg life depends on the duration of embryonic diapause. The nature of diapause in silkworm, Bombyx mori, is primarily determined by genetic characters and endocrinologicnl mechanisms, mediated by environmental factors such as temperature and photoperiod. Hibernating potency value besides nucleic acid and carbohydrate metabolism, production and utilization of sorbitol are also equally responsible for induction, initiation, determination, maintenance and termination of diapause. Embryonic diapause in Bombyx moir, induced by active secretion of sub-oesophageal ganglion is attributed to hormonal system and metabolic adjustment, which serves to bring about a new physiological state. Metabolic conversion of trehalose to glycogen at induction, glycogen to sorbitol at initiation and sorbitol to glycogen at termination of diapause is correlated and in each metabolic shift a key enzyme becomes active in response to hormonal and environmental stimulation. An attempt has been made in this review article to discuss briefly the nature of embryonic diapause, influence of various factors on diapause nature, hormonal mechanism of diapause besides biochemical composition of egg, nucleic acid and carbohydrate metabolism, production and utilization of sorbitol in relation to induction, determination, maintenance, initiation and termination of diapause in the silkworm, Bombyx mori.

KBPT is the fortified prescription of Bang-pung-tong-sung-san(BPTS) by adding Spatholobi Clulis and Salviae Miltiorrzae Radix. BPTS prescription has been utilized in oriental medicine for the treatments of vascular diseases including hypertension, stroke, and arteriosclerosis. Yet, the overall mechanism underlying its activity at the cellular levels remains unknown. Using spontaneously hypertensive rat (SHR) model, we investigated whether the KBPTS has an effect on the pathophysiological parameters related to hypertension. Pretreatment of SHR with KBPTS was found to lower blood pressure and heartbeat rate. Levels of aldosterone. dopamine, and epinephrine were found to be significantly reduced in the serum of KBPTS-treated SHR. Histological examination of adrenal cortex and superior aorta showed that tissues from KBPTS-treated SHR rats were more intact and cleaner compared to saline-treated control. Levels of superoxide dismutase (SOD) protein in adrenal gland, aorta, myocardial tissue, and kidneys were higher in KBPTS-treated animals than control group. The present data suggest that KBPTS may play a role in normalizing cardiovascular function in SHR by controlling hypertension-related blood factors and superoxide stressors.

Hippocampal slice models can be a powerful tool to study the mechanism of partial epilepsy. Despite the loss of connection with the rest of the brain, in vitro hippocampal slice preparations allow detailed physiological and pharmacological studies, which would be impossible, in vivo. There are several methods to induce electrographic seizures on hippocampal slice models. Those are electrical pulse train stimulation, 0 $Mg^{2+}$ artificial cerebrational fluid and high concentration of extracelluar $K^+$ on bath. Among them, the electrically triggered seizure may mimic the physiological communication between neuronal populations without any deterioration of normal physiologic and chemical status of the hippocampal slice models. Presumably, such communication from hyperexcitable areas to other neuronal populations is involved in the development of epilepsy. Electrographic seizures in hippocampal slice models occur in the network of neurons that are involved in epileptic seizures in the hippocampus in vivo. Because these models have many advantages and are very valuable to research of epileptogenesis on partial epilepsy, I would like to introduce the electrophysiological methods to induce electrographic seizure or epilepsy on hippocampal slice models briefly in this paper.
