  • Objective : There are many reports that acupuncture has thermoregulatory effects on human and animals. To investigate the effect and mechanism of antipyretic action of acupuncture, we observed the body temperature and cytokine expressions in the hypothalamus of rats. Methods : Lipopolysaccharide (LPS, i.p., 2.5mg/kg) was injected to conscious rats (Sprague-Dawley, male, n=4l) to cause hyperthermia and simple needling (stainless steel, 0.25 mm o.d., 5 mm insertion for 10 sec with no manipulation) was performed bilaterally with the measurement of rectal temperature. Next, we sacrificed rats to remove brain and determined the level of mRNA for interleukin-6 (IL-6), $interleukin-1{\beta}{\;}(IL-1{\beta})$, interleukin-2 (IL-2) and $interferon-{\gamma}{\;}(IFN-{\gamma})$ in the hypothalamus by using reverse transcriptase-polymerase chain reaction (RT-PCR). Resul1s : Needling on forepaw (acupoint HT8) and needling on hindpaw (acupoint BL66 and acupoint LR2) significantly inhibited LPS-induced fever of rats (P<0.01, 10 min after treatment respectively), but same treatment on proximal tail (non-acupoint) did not cause any change on fever. The levels of IL-6 and $IL-1{\beta}$ mRNA in the hypothalamus was significantly enhanced by LPS-injection, while the level of IL-6 and $IL-1{\beta}$ mRNA was markedly reduced after treatment on BL66 (P<0.01). Treatment on forepaw reduced it slightly, but not significantly. Equivalent stimulation on proximal tail did not cause any changes. Conclusions : Our results indicate that acupuncture stimulation on various body parts has differential thermoregulatory effects on LPS-induced fever of rats with site-specificity. And, we suggest that its antipyretic action might be accompanied with the suppression of hypothalamic production of pro-inflammatory cytokine of immune system, IL-6 and $IL-1{\beta}$.

  • Objectives : The authors aimed at contributing to the safety of acupuncture in the clinic by analyzing the information of contraindicated acupoints described in Uihakipmun. Methods : We investigated the contents related acupuncture contraindications in Uihakipmun, categorized the contraindicated acupoints by site and identified whether they can cause adverse events from the anatomical point of view. Results : In Uihakipmun, 49 acupoints - BL6, BL8, BL9, ST1, SI18, BL1, BL2, TE18, TE19, TE20, GB1, GB3, GV22, GV24, ST12, ST9, TE16, GV6, BL15, BL30, CV17, LU2, GB22, SP16, CV8, CV9, CV15, KI11, ST30, SP11, BL56, GB32, GB33, GB42, LI13, HT2, TE8, GV17, GB18, EX-HN11, GB21, GV11, GV10, ST17, CV5, CV1, ST42, SP6, LI4 - were described as contraindicated acupoints. Among them, the contraindications induced by acupuncture treatment were described for just 5 acupoints. Anatomically, acupuncture stimulation at the contraindicated acupoints can cause organ, nerve or vessel damage near the acupoints. And the number of contraindicated acupoints in Uihakipmun was increased compared to those in Hwangjenaegyeong, Chimgugabeulgyeong, Bigeupcheongeumyobang, Donginsuhyeolchimgudogyeong and Chimgujasaenggyeong. Conclusions : In Ming dynasty, the knowledge associated with adverse events on acupuncture was increased by the accumulation of medical knowledge. Acupuncture stimulation at the contraindicated acupoints described in Uihakipmun can cause tissue damage, therefore we should perform acupuncture procedure carefully to avoid adverse events when stimulating the contraindicated acupoints.

  • Although research efforts for brain waves have prospered in medicine and engineering, acupuncture still has a long way to go regarding researches on brain waves analysis. Thus this study set out to analyze brain waves stimulated by indirect mugwort moxibustion, which was part of acupuncture techniques, and to investigate their correlations with the automatic nervous system. For the experiments, stimulation was given to Jungwan, Shingwol and Gwanwon, which were some of the spots on the body suitable for acupuncture, through indirect mugwort moxibustion. The subjects' brain waves were measured before the stimulation, during the stimulation, and one hour and two hours after the stimulation. The measurements were analyzed with Matlab 7.0 for FFT and frequency power spectrum. Then the ${\alpha}$, ${\beta}$, ${\delta}$, and ${\theta}$ waves were analyzed and examined for changes to the percentage of each frequency and to the amplitude of vibration according to the stages of stimulation. The EEG data of the entire brain were translated into FFT to analyze the percentage of the ${\alpha}$, ${\beta}$, ${\delta}$, and ${\theta}$ waves. As a result, the ${\alpha}$ waves recorded a double increase after the stimulation. The power spectrum analysis results of the entire brain decreased the ${\alpha}$ and ${\beta}$ waves dropping in the energy level, which suggested that the parasympathetic nerves were activated. When the results of the study were compared with those of the previous study, it's confirmed that indirect moxibustion stimulation could cause changes to the automatic nervous system and bring stability to those who were nervous or under stress due to the proportionate increase of the ${\alpha}$ waves.

  • Empty follicle syndrome (EFS) is a condition in which no oocytes are retrieved after an apparently adequate ovarian response to stimulation and meticulous follicular aspiration. EFS can be classified into 'genuine' and 'false' types according to hCG levels. It is a rare condition of obscure etiology. The existence of genuine EFS has been questioned and is still controversial. The limitation around EFS is that the definition of EFS is obscure. Management of patients with EFS is a challenge to physicians. No single treatment is known to be universally effective. However, patients should be adequately informed regarding the importance of correct hCG administration because improper hCG administration is a common and preventable cause of EFS. EFS is a syndrome that deserves additional study because such investigation could lead to a further understanding of ovarian biology and infertility.

  • Staphylococcus aureus, the most salt-tolerant food-borne pathogen, produces enterotoxins which may cause symptoms such as vomiting, diarrhea, nausea, and cramps. Since this bacterium has been able to grow at extremely high osmolarity its identity in foods with low water activity values such as salted or dried foods is of great concern. In this study, the growth of S. aureus at high osmolarity has been studied and the doubling time of S. aureus grown at TSB medium containing 15% NaCl has been found to be increased to 4∼5 hours. The stimulation of proline uptake after exposure of cells to high concentration of both extracellular KCl and sucrose was not increased. Stimulation of proline uptake at these environment only occured when 25mM NaCl was present I transport buffer. In additional experiments, the time required to reach mid-logarithmic phase in defined medium of high osmolarity found to be reduce by the presence of glycine betaine, proline, and choline.

  • According to the literatual study on the Infantile Vomiting since the publication of ${\ll}Hwangjenaekung{\gg}$, the results were as follows. 1. The causes of vomiting are classified into the following kind: external cause are the cold and heat, not external and internal are disorder of food and mood, internal are the dysfuntion of spleen, stomach, liver, kidney. 2. The Oriental Medical cause of Infantile Vomiting is disorder of food, intusion of outside evil, heat accumulation in the stomach, deficiency of stomach liquid, reverse flowing of Qi resulted from fear and being frightened. There are so many causes of Infantile Vomiting, but they are all related to the stomach. 3. The Western Medical cause of Infantile Vomiting are classified with the situation of stimulation, age, accompanied symptom. The main cause related with the age is inhalation of amniotic fluid, maternal blood, infectious disease, wrong lactation method, functional and organic abnormality. 4. The Infantile Vomiting is similar with the adults, but the spleen and stomach of infants is so feeble that the vomiting happens very easily. The reverse flowing of Qi resulted from fear and being frightened and disorder of food are the main cause in infants. 5. The cause of Infantile Vomiting between Oriental Medicine and Western's is so similar and both emphasized the function of spleen and stomach. But the comment on the external cause(cold, heat) and not internal & external cause(mood disorder) is a creative view of Oriental Medicine.

  • Laryngeal evoked EMG is the objective and quantitative method to measure the innervation of laryngeal muscle. If there is a mobility disorder of vocal cords, the cause and location of neural lesion co be understood by the laryngeal evoked EMG and if there is a vocal cord paralysis, the degree of recovery and the policy of treatment can be determined by it. Recently, the studies of reinnervation after recurrent laryngeal nerve injury have been actively carried out. Laryngeal evoked EMC is useful to these studies. The aim of study is to know whether noninvasive methods for stimulating the recurrent laryngeal nerve and for recording of compound action potential(CAP) using surface electrode are as useful as the invasive method using needle electrode. We obtained EMG of laryngeal muscle by various stimulating and recording methods : 1) Direct nerve stimulation by placing nerve cuff electrode made out of silastic tube and platinum wire and recording by insertion of hook wire electrode into posterior cricoarytenoid(PCA) and thyroarytenoid(TA) muscles, respectively. 2) Recording of compound action potential by surface electrode after stimulation of recurrent laryngeal nerve by the insertion of 27 gauge of needle electrode. 3) Recording of compound action potential by surface electrode after stimulating the recurrent laryngeal nerve by transcutaneous blunt rod electrode at tracheoesophageal groove. The amplitude, duration and latency of the CAP evoked by recurrent laryngeal nerve stimulation were compared among the three groups. The amplitude of CAP was smallest in the group recorded from posterior cricoarytenoid and hyroarytenoid muscle, and that recorded by surface electrode after stimulation by needle electrode was largest. The difference in amplitude between the group by hook wire recording and the two groups by surface electrode recording was significant statistically. There is no significant difference in duration and latency among three groups. Since the waveform of CAP from all three methods has similar duration, latency, we concluded that noninvasive method is a useful as invasive methods.

  • The relationship between pain stimulation and the blood glucose level was studied in ICR mice. We examined the possible change of the blood glucose level after the pain stimulation induced by acetic acid injected intraperitoneally (i.p.),, formalin injected subcutaneously (s.c.) into the hind paw, or substance P (SP), glutamate, and proinflammatory cytokines (TNF-${\alpha}$ and IFN-${\gamma}$) injected intrathecally (i.t.). We found in the present study that acetic acid, formalin, SP, TNF-${\alpha}$, and IFN-${\gamma}$ increased the blood glucose level. The blood glucose level reached at maximal state 30 min and returned to normal level 2 h after the pain stimulation in a fasting group. Furthermore, acetic acid, formalin, SP, TNF-${\alpha}$, and IFN-${\gamma}$ caused the elevation of the blood glucose level in D-glucose-fed group only in an additive manner. However, i.t. injection of glutamate did not alter the blood glucose level in a fasting group. In contrast, i.t. injection of glutamate enhanced the blood glucose level in the D-glucose-fed group. Our results suggest that the blood glucose level appears to be differentially regulated by various pain stimulation induced by acetic acid, formalin, SP, glutamate, and pro-inflammatory cytokines.

  • We are exposed to the various external stimuli input from the environment, which cause emotional changes based on the characteristics of the stimuli. Unfortunately, there are no quantitative results on relationship between human sensibility and the characteristics of physiological signals. The objective of this study was to quantify EEG signals evoked by auditory stimulation based on the assumption that the analysis of the variability on the characteristics of the EEG waveform may provide the significant information regarding changes in psychological states of the subject. The experiment was devised with seven experimental conditions, which are control and six different types of auditory stimulation. Twenty subjects were used to obtain EEGs while introducing auditory stimulation. Wavelet transformation was employed to analyze the EEG signals. The results showed that the reconstructed signals at the decomposition level revealed the different energy value on the EEG signals. Also, general patterns of EEG signals in rest state compare with negative and positive stimulus were found. This study could be extended to estabilish an algorithm which distinguishes psychophysiological states of the subjects exposed to the auditory stimulation.

  • Alzheimer's disease (AD) is the most common cause of dementia, showing progressive neurodegeneration. Although oral medications for symptomatic improvement still take a huge part of treatment, there are several limitations caused by pharmacology-based real world clinic. In this respect, non-pharmacologic treatment for AD is rising to prominence. Transcranial direct current stimulation (tDCS) is a one of the non-invasive neuromodulation technique, using low-voltage direct current. In terms of safety, tDCS already has been proven through numerous previous reports. This review focused on behavioral, neurophysiologic and histopathologic improvement by applying tDCS in AD rodent models, thereby suggesting reliable background evidence for human-based tDCS study.
