ABSTRACT: Cue reactivity is a key factor that modulates motivational goal directed behavior associated with compulsive drug intake and relapse. We investigated the effect of acupuncture on the selective attention to smoking-related visual cues in smokers, as an index of the severity of drug dependence.
Twenty-nine smokers received real acupuncture (n=15) or sham acupuncture (n=14) to the acupuncture point HT7 (Sinmun) for 2 consecutive days after quitting smoking. A visual probe task was used to measure the attentional bias using neutral or smoking visual cues after the second acupuncture stimulation. The cigarette withdrawal scale was also measured on the same day.
The real acupuncture group showed markedly attenuated attentional bias towards smoking cues. The real acupuncture group exhibited significant decrease in withdrawal symptoms compared to the sham acupuncture group. The attentional bias revealed a significant positive correlation with the smoking withdrawal symptoms (r=0.430, p<0.05).
Acupuncture treatment ameliorated the smoking withdrawal symptoms as well as the selective attention to smoking-related visual cues in smokers. The selective attention to smoking cues was associated with the degree of the cigarette withdrawal symptoms.

ABSTRACT: To find new biomarkers by stimulating acupuncture point GB34 (Yangneungcheon) which has neuroprotective effect on the mouse model of Parkinson's disease, analysis of cDNA microarray on mRNAs of the substantia nigra was performed.
Male C57BL/6 mice were divided into two groups: 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine-treated mice (MPTP group, n=3); 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine and acupuncture (GB34)-treated mice (MPTP + ACU group, n=3). The mice received an intraperitoneal injection of 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (30 mg/kg) once daily for 3 consecutive days. Manual acupuncture was performed 2 hours after every injection of 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine. The total RNA in the substantia nigra of each mouse was isolated on 3 days after the last 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine injection. Agilent mouse whole genome 44K chip was used for microarray analysis and the hybridization image was analysed by GenePix Pro 6.0. Data normalization and analysis were performed using GeneSpring GX 7.3.1 program.
The acupuncture stimulation revealed 799 genes (424 up- and 375 down-regulated) of which expression levels were changed more than two-folds in the MPTP + ACU group, compared to the MPTP group. The genes selected were classified into several categories based on their functions using DAVID Bioinformatics Resources 2008 (http://david.abcc.ncifcrf.gov/) and KEGG PATHWAY Database (http://www.genome.jp/kegg/pathway.html).
Biomarkers in response to acupuncture stimulation to GB34 were identified in a mouse model for Parkinson's disease. These biomarkers might provide a promising clue for understanding the neuroprotective effect of acupuncture in Parkinson's disease.

ABSTRACT: The aim of this study was to investigate the effect of acupuncture to the acupuncture point HT7 (Sinmun) on morphine-induced behavioral sensitization and the neuronal changes in nucleus accumbens and striatum in rats.
Male Sprague-Dawley rats were given repeated injections of morphine hydrochloride for 5 days followed by 3 day withdrawal and one challenge injection. The acupuncture treatment was performed for 1 minute once a day for 3 days of withdrawal period and its effect on morphine-induced changes of locomotor activity and Fos expression was examined.
The acupuncture stimulation to HT7 significantly suppressed the morphine-induced increases in the locomotor activity and Fos expression in the nucleus accumbens and striatum, as compared to the controls of non-acupoint or the acupoint on other meridian.
These results demonstrated that the inhibitory effect of the acupuncture stimulation to HT7 on morphine-induced behavioral sensitization was closely associated with the suppression of dopamine biosynthesis and its activity in the post-synaptic neurons in nucleus accumbens and striatum. It means that the behavioral effect of the acupuncture can originate from the modulation of the same neuronal mechanism in the central dopaminergic system as in the morphine-induced behavioral sensitization. This modulation was also strictly confined to the stimulation of the specific acupoint, because the stimulation to other acupoint (TE5) on another meridian did not show the modulating effect despite being relatively close to each other. It can be therefore suggested that the acupuncture stimulation has an acupoint-specific property, and might be a useful therapeutic alternative with few side effects for treating morphine addiction.

ABSTRACT: To determine the association between Four Constitutional classification and Fc fragment of IgG, low affinity of IIa, receptor (FCGR2A) and interleukin 1 receptor antagonist (IL1RN) in Korean ischemic stroke patients.
We classified the Four Constitutional types in ischemic stroke patients (n=162) and healthy control subjects (n=135), and genotyped FCGR2A and IL1RN polymorphisms using direct DNA sequencing and polymerase chain reaction (PCR) methods.
In the IL1RN polymorphisms, the IL1RN*1/IL1RN*2 genotype (OR=5.80, p=0.0142), and in the FCGR2A polymorphisms, the rs7535475 (OR=0.58, p=0.0218) and rs7512140 (OR=0.09, p=0.0335), were significantly associated with ischemic stroke. The prevalence of IL1RN*1/IL1RN*2 genotype of IL1RN and rs7535475 of FCGR2A in greater Yin person ischemic stroke patients were different from greater Yin person healthy controls (OR=18.97, p=0.0063; OR=0.38, p=0.0045).
These results suggest that IL1RN*1/IL1RN*2 genotype in greater Yin person might be associated with increased risk of ischemic stroke, and rs7535475 of FCGR2A might be associated with decreased risk of ischemic stroke. Furthermore, this relationship could provide the basis for a new approach in investigating the etiology of ischemic stroke.

ABSTRACT: Early stressors can influence the development of biological and neurological systems. Maternal separation (social isolation) in early life may increase vulnerability to neurodegenerative diseases and neuropsychiatric disorders over the lifespan. To identify new proteins on acupuncture effects in maternally separated rats, an animal model for study of early environmental insults, proteomic approach on the expression of the hypothalamic proteins was performed.
On post-natal day 14, rat pups were randomly divided into four groups: pups kept with their mothers for 7 days; pups kept with their mothers with acupuncture daily to HT8 (Sobu); maternally separated pups; maternally separated pups with acupuncture. The hypothalamic proteins were analysed by two-dimensional electrophoresis coupled with matrix assisted laser desorption/ionization time-of-flight mass spectrometer.
The results showed that 27 spots were differentially and commonly expressed. Of 27 spots, 21 spots were identified while six spots were not, and 15 proteins were known proteins. In maternally separated group, the expressions of 14 proteins were down-regulated, compared to control group. In group of maternally separation with acupuncture, five proteins were down-regulated and nine were up-regulated, compared to the maternally separated group. Among nine proteins up-regulated by acupuncture treatment, we found four proteins (dihydropyrimidinase-like 2, dystrophin-related protein 2, tubulin, alpha 1a and syntaxin 1b) related to neurodevelopment.
The result suggests that acupuncture to HT8 may affect neurodevelopment, and acupuncture may be a possible therapy for neurodevelopmental disorders.

ABSTRACT: Acupuncture has been known to be effective in ischemia, and glutamate excitotoxicity is an important factor for the neuronal cell death. We examined the effect of acupuncture on glutamate level in the ischemic stroke model.
A global ischemia was induced using the method of 11-vessel occlusion in rat. Rats were randomly divided into two groups: the control group (n=5, with 11-vessel occlusion) and the acupuncture group (n=5, with 11-vessel occlusion + acupuncture). The extracellular glutamate level was assessed using an intracerebral biosensor system measuring 256 samples per second. Simultaneously, the cerebral blood flow was measured and the electroencephalogram data were recorded. The time schedule of the experiment was as follows: 10 minutes of baseline measurement, 10 minutes of occlusion and 30 minutes of follow-up monitoring. Acupuncture stimulation was applied to the acupuncture points GB34 (Yangneungcheon) and GB39 (Hyeonjong) during the occlusion period.
In the control group, the extracellular glutamate level was changed as 135.19 +/- 23.76 microM (mean +/- standard deviation) from the baseline level. However, this increase was suppressed in the acupuncture group (72.20 +/- 27.15 microM, p<0.01 versus the control group). The changes of cerebral blood flow and electroencephalogram were not significantly different between the groups.
This result suggests that the effect of acupuncture might be closely associated with modulation of the brain glutamate release in the ischemic condition.

ABSTRACT: Biophoton emissions from three healthy human subjects were measured for 52 weeks. The active nature of dorsal hands and personal discernable patterns in palmar hands were investigated through frequency count analysis of biophoton emission rates. Also, the seasonal dependency of biophoton emission rates from human hands was studied and we found that emission rates were lowest in autumn. There was a reversion of relative emission rates from the palms and the dorsa depending upon the season. The emission rates from the palms remain rather stable throughout the year, but those from the dorsa vary widely depending upon the season. These features of biophoton emission rates were considered in light of the diagnostic view of traditional Chinese medicine.

ABSTRACT: Yearlong measurements of biophotons from palm and back of hand of three healthy people were performed. The detection of biophoton was done with two photomultiplier tubes whose spectral range was from 300 nm to 650 nm. The measurement was done on a circular area of diameter 46 mm whose centers were at the acupuncture point Laogong (PC8) of a palm and the mid-point of a back, respectively. The emission rates from the dorsa showed strong seasonal dependence which is consistent with the active nature of Yang meridians, while the palm sides show less seasonal dependence as they belong to the passive Yin meridians. This could be quantified simply by the standard deviations from the yearly average: They were 47.6 counts per second (cps), 66.1 cps and 66.0 cps from the dorsa, and 23.8 cps, 29.7 cps and 30.4 cps from the palms of subject 1, 2 and 3, respectively. Biophoton emission revealed qualitative individual tendencies: The subjects 1 and 2 emitted more strongly from the left dorsa, while the subject 3 from the right dorsum. The left-right balance of biophoton emission was well kept for normal people, which is in contrast with the severe imbalance for some stroke patients. Thus biophoton measurement has a diagnostic potential that encourages more studies.

ABSTRACT: Biophotons emitted from the center of fingernails and fingerprints from living humans are measured for twenty healthy subjects. We devised a dark box with a photo multiplier tube (H6180-01, Hamamatsu, Japan) whose spectral range is 300 nm to approximately 650 nm and a mount with a light-receiving hole of diameter 8 mm such that biophotons from the small circular area of nail or print of each finger are detected. Significantly more biophotons are emitted from fingernail than fingerprint for each finger of every subject. For thumb the average biophoton emission rate is 23.0 +/- 4.5 counts per second, and 17.2 +/- 2.0 counts per second from the nail, and print, respectively. There is a slight tendency that the little finger emits less than the other fingers. But some fingers emit far stronger than others, and it depends upon each individual subject which finger emits strongest.
