Morphine-induced locomotor response and Fos expression in rats are inhibited by acupuncture.

Objectives: 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.

Methods: 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.

Acupuncture attenuates extracellular glutamate level in global ischemia model of rat.

Objectives: 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.

Methods: A global ischemia was induced using the method of 11-vessel occlusion in rat.

Gene expression profile of acupuncture treatment in 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine-induced Parkinson's disease model.

Objectives: 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.

Methods: 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.

Effect by acupuncture on hypothalamic expression of maternally separated rats: proteomic approach.

Objectives: 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.

Susceptibility for ischemic stroke in four constitution medicine is associated with polymorphisms of FCGR2A and IL1RN genes.

Objectives: 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.

Methods: 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.

Results: In the IL1RN polymorphisms, the IL1RN*1/IL1RN*2 genotype (OR=5.

Effect of acupuncture on selective attention for smoking-related visual cues in smokers.

Objectives: 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.

Methods: 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.

Left-right and Yin-Yang balance of biophoton emission from hands.

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.

Year-long biophoton measurements: normalized frequency count analysis and seasonal dependency.

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.

A study of Korean femoral geometry.

The current authors investigated the anatomic geometry of femurs from Korean subjects and compared the results with those of femurs from American and Japanese subjects. Thirty-eight femurs extracted from cadavers and 200 femurs of healthy subjects were used. The 38 femurs were placed on a horizontal plane to obtain computed tomography images, which then were transformed into bitmap images, and the computed tomography images of the 200 femurs of healthy subjects also were obtained.

Biophoton emission from fingernails and fingerprints of living human subjects.

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.
