The purpose of this study was to evaluate whether berberine (BER) administration could attenuate depression- and anxiety-like behaviors and increase corticotrophin-releasing factor (CRF) and tyrosine hydroxylase (TH) expression following chronic morphine withdrawal in rats. Male rats were exposed to chronic, intermittent, escalating morphine (10~50 mg/kg) for 10 days. After the last morphine injection, depression- and anxiety-like beahvior associated with morphine discontinuation persisted for at least three days during withdrawal without any change in ambulatory activity. Daily BER administration significantly decreased immobility in the forced swimming test and increased open-arm exploration in the elevated plus maze test. BER administration also significantly blocked the increase in hypothalamic CRF expression and TH expression in the locus coeruleus (LC) and the decrease in hippocampal brain-derived neurotrophic factor (BDNF) mRNA expression. Taken together, these findings demonstrated that BER administration significantly reduced morphine withdrawal-associated behaviors following discontinuation of repeated morphine administration in rats, possibly through modulation of hypothalamic CRF and the central noradrenergic system. BER may be a useful agent for treating or alleviating complex withdrawal symptoms and preventing morphine use relapses.

Infantile Convulsion, one of common emergency symptoms in pediatrics, arises from sudden derangement of the central nerve system, and can cause a sudden loss of consciousness and spasm. It falls into three categories: Acute Infantile Convulsion, Chronic Infantile Convulsion and Chronic Spleen Convulsion. According to research, approximately 6~7% of all babies undergo spasm more than once. Since the treatment must be done immediately, acupuncture & moxibustion treatment can be one of the most important treatments in this Particular case. Therefore, the focus of this study is on how acupuncture & moxibustion can be utilized in the treatment of Infantile Convulsion, and the literary findings are as follows: 1. The meridian points used on acute infantile convulsion are Sugu(GV26), T'aech'ung(Liv3), Hapkok(LI4). 2. The meridians used on acute infantile convulsion are Governor Vessel(GV), Bladder Meridian(BL), Stomach Meridian(ST). 3. The meridian points used on accompanied symptoms with acute infantile convulsion are Haenggan(Liv2), Yangnungch'on(Liv3) on spasm, Paek'oe(GV14) on opisthotonus, Kokchi(LI11), Taech'u(GV14) on fever, Nogung(P8), Yongch'on(K1) on fainting spell, Chok-samri(S36) on body weakness. 4. The meridian points used on chronic infantile convulsion are Shinguol(CV8), Ch'onchj'u(S25), T'aech'ung(Liv3), Kwanwon(CV4), Ch'ukt'aek(L5). 5. The meridians used on chronic infantile convulsion are Conception Vessel(CV), Governor Vessel(GV), Stomach Meridian(ST). 6.

In this study, we assessed the effects of ginsenoside Re (GRe) administration on repeated immobilization stress-induced behavioral alterations using the forced swimming test (FST), the elevated plus maze (EPM), and the active avoidance conditioning test (AAT). Additionally, we examined the effect of GRe on the central adrenergic system by observing changes in neuronal tyrosine hydroxylase (TH) immunoreactivity and brain-derived neurotrophic factor (BDNF) mRNA expression in the rat brain. Male rats received 10, 20, or 50 mg/kg GRe (i.p.) 30 min before daily exposures to repeated immobilization stress (2 h/day) for 10 days. Activation of the hypothalamic-pituitary-adrenal (HPA) axis in response to repeated immobilization was confirmed by measuring serum levels of corticosterone (CORT) and the expression of corticotrophin-releasing factor (CRF) in the hypothalamus. Repeated immobilization stress increased immobility in the FST and reduced open-arm exploration in the EPM test. It also increased the probability of escape failures in the AAT test, indicating a reduced avoidance response. Daily administration of GRe during the repeated immobilization stress period significantly inhibited the stress-induced behavioral deficits in these behavioral tests. Administration of GRe also significantly blocked the increase in TH expression in the locus coeruleus (LC) and the decrease in BDNF mRNA expression in the hippocampus. Taken together, these findings indicate that administration of GRe prior to immobilization stress significantly improved helpless behaviors and cognitive impairment, possibly through modulating the central noradrenergic system in rats. These findings suggest that GRe may be a useful agent for treating complex symptoms of depression, anxiety, and cognitive impairment.

Objective : The meridian theory in oriental medicine explains that Sp9(Yinlingquan) has been considered very important for gynecological disorders, spleen and stomach disorders, and water metabolic disorders. Functional MRI is the best method of showing the evidences of the effect of the Electro-acupuncture treatment through scientific methods. On this supposition, Electro-acupuncture stimulation on Sp9(Yinlingquan) was carried out on six healthy volunteers, using the gradient echo sequence with the 3.0T whole-body MRI system(ISOL). Methods : Electro-acupuncture stimulation on Sp9(Yinlingquan), the experiment was carried out on six healthy volunteers, using the gradient echo sequence with the 3.0T whole-body MRI system(ISOL). After the needle insertion on right Sp9(Yinlingquan), 2Hz of electric stimulation was given for 30 seconds, repeated five times, with 30 seconds' intervals. The Image analysis including motion correction, talairach transformation, and smoothing was done using SPM99. Results : The electro-acupuncture stimulation on Sp9(Yinlingquan) activates Brodmann Area 13, 19, 22, 39, 40, 47 which may be the central pathways of the electro-acupuncture stimulation on Sp9(Yinlingquan). We also hypothesize that those brain areas may be directly or indirectly related with the mechanism of the effect of electro-acupuncture stimulation on Sp9(Yinlingquan).

Objectives : Acupuncture is expected to have somewhat like the efficacy parallel increasing activity of immune system in Western modem medicine. There, already, are many animal researches on activating effect of acupuncture for the immune system in peripheral organs. So, we carried out this experiment to see whether acupuncture has controlling effect on interleukin-6(IL-6) activity in rat's brain. Methods and Results : We had topical application of IL-6(1U=lpg, $10{\mu}l$) on brain of rat. It reduced afferent sensory transmission to the primary somatosensory(SI) cortex from periphery. Whereas, electrical stimulation(ES, 2Hz, 1.5V, 15min) of ST36(足三里) with application of IL-6 prominently activated afferent sensory transmission. ES of non-acupoint(proximal tail) with IL-6 showed suppression of afferent transmission. ES of ST36 without IL-6 application also exerted facilitation of afferent transmission to the SI cortex. Conclusions : Electoacupuncture(EA) on ST36 has noticeable influences on modulating activation of IL-6 in central nervous system, which do major role in immune system.

Objective : Zhang zhi-cong insisted the theory related to the 'Six-meridian qi transformation', and Zhen xiu-yuan inherited that theory understanding six-meridian disease of "Shang-Han-Lun". This emphasizes that the disease of 'three yin and three yang' in "Shang-Han-Lun" is a disease caused by Six-meridian qi transformation, not a lesion of meridian itself. He said, "If you do not know brightly in the 'Tip, Root and Middle qi', you can not read the "Shang-Han-Lun"." Therefore, in this paper, we examine the interpretation of the "Shang-Han-Lun"by using the theory of 'five circuits and six qi'. Method : First, extract sentences related to 'Tip, Root and Middle qi' from the sentences of "Shang-Han-Lun" Second, the sentence is interpreted through the Zhen xiu-yuan's "Sang han lun qian zhu". Third, the meaning of the sentence is examined and summarized. Result : Zhen xiu-yuan proposed a clear and systematic theory that can understand the meaning of Six-meridian in "Shang-Han-Lun", by utilizing the discipline that 'Tip, Root and Middle qi' Conclusion : The change of 'Tip, Root and Middle qi' is a very central theory that explains the properties of 'Yin and Yang' and mutual correspondence among Korean medicine theories. It also provides basic directions for understanding the changing patterns of disease.

We investigated the anxiolytic-like activity of ${\alpha}$-asarone (AAS) from Acorus gramineus in an experimental rat model of anxiety induced by repeated administration of the exogenous stress hormone corticosterone (CORT). The putative anxiolytic effect of AAS was studied in behavioral tests of anxiety, such as the elevated plus maze (EPM) test and the hole-board test (HBT) in rats. For 21 consecutive days, male rats received 50, 100, or 200 mg/kg AAS (i.p.) 30 min prior to a daily injection of CORT. Dysregulation of the HPA axis in response to the repeated CORT injections was confirmed by measuring serum levels of CORT and the expression of corticotrophin-releasing factor (CRF) in the hypothalamus. Daily AAS (200 mg/kg) administration increased open-arm exploration significantly in the EPM test, and it increased the duration of head dipping activity in the HBT. It also blocked the increase in tyrosine hydroxylase (TH) expression in the locus coeruleus (LC) and decreased mRNA expression of brain-derived neurotrophic factor (BDNF) and its receptor, TrkB, in the hippocampus. These results indicated that the administration of AAS prior to high-dose exogenous CORT significantly improved anxiety-like behaviors, which are associated with modification of the central noradrenergic system and with BDNF function in rats. The current finding may improve understanding of the neurobiological mechanisms responsible for changes in emotions induced by repeated administration of high doses of CORT or by elevated levels of hormones associated with chronic stress. Thus, AAS did exhibit an anxiolytic-like effects in animal models of anxiety.

Many studies have suggested that the behavioral and reinforcing effects of morphine are induced by hyperactivation of the mesolimbic dopaminergic system, which results in increases in locomotor activity, c-Fos expression in the nucleus accumbens (NAc), and tyrosine hydroxylase (TH) in the ventral tegmental area (VTA). In order to investigate the effect of wild ginseng (WG) on treating morphine addiction, we examined the behavioral sensitization of locomotor activity and c-Fos and TH expression in the rat brain using immunohistochemistry. Intraperitioneal injection of WG (100 and 200 mg/kg), 30 min before administration of a daily injection of morphine (40 mg/kg, s.c.), significantly inhibited morphine-induced increases in c-Fos expression in NAc and TH expression in VTA as well as in locomotor activity, as compared with Panax ginseng. It was demonstrated that the inhibitory effect of WG on the behavioral sensitization after repeated exposure to morphine was closely associated with the reduction of dopamine biosynthesis and postsynaptic neuronal activity. It suggests that WG extract may be effective for inhibiting the behavioral effects of morphine by possibly modulating the central dopaminergic system and that WG might be a useful resource to develop an agent for preventing and treating morphine addiction.
