Objectives : The purpose of this study is to investigate the anti-oxidative effect of electroacupuncture at Shinmaek($BL_{62}$) in rats. Methods : In order to cause oxidative stress, AAPH was administered to the abdominal cavity of rats, after we stimulated $BL_{62}$ of the rat by electroacupuncture. Blood test and anti-oxidative test(LDL-cholesterol, GOT, GPT SOD, GSH, catalase, NO, MDA) were performed at the end of treatment. Results: 1. SOD, glutathione, catalase activity were significantly increased in the $BL_{62}-EA$ group compared with the holder group. 2. NO density was significantly decreased in the $BL_{62}-EA$ group compared with the holder group. 3. Glutathione was significantly increased in the $BL_{62}-EA$ group compared with the sham-EA group. Conclusion : These results suggest that electroacupuncture at $BL_{62}$ has an anti-oxidant effect in human.

Objectives : The purpose of this study is to review needling depth and location of LU7, BL62 and KI6 by the medical classics' records. Methods : 1. We researched the medical classics describing LU7, KI6 and BL62, and reorganized data about the location and needling depth. 2. We compared the medical classics' records on LU7, KI6 and BL62 with description of WHO standard acupuncture point location. 3. We reviewed different location and needling depth of LU7, BL62, and KI6 recorded in the medical classics with the anatomical structure. Results : 1. The common needling depth of LU7 is about 0.2 chon. But in some medical classics, the depth of LU7 is 0.8 chon. Needling depth of LU7 varied depending on the patient's hand posture. In the 'half-up' position with the thumb upward, it is possible to stimulate acupuncture on LU7 by 0.8 chon because there is a space between the tendons. 2. In WHO standard acupuncture point location, the locations of BL62 and KI6 are just below the lateral and medial malleolus. But in some medical classics, the locations of BL62 and KI6 are between the bones and muscles below the malleolus. In the locations between the bones and muscles below the malleolus, it is possible to stimulate acupuncture on BL62 and KI6 by penetrating acupuncture because there is no bone structure. Conclusions : 1. By the 'half-up' position with the thumb upward, it is possible to stimulate vertically acupuncture on LU7 by 0.8 chon. 2. By the locations of BL62 and KI6 between the bones and muscles below the malleolus, it is possible to stimulate on BL62 and KI6 by penetrating acupuncture.

Objectives: Recently, the effect of acupuncture has been approved not only in the East but also in the West, so the interest on acupuncture was greatly improved. Especially, functional magnetic resonance imaging(fMRI) was embossed as the study tool for the mechanism of acupuncture noninvasively and many studies on the mechanism of acupuncture using fMRI were carried out. We archived the fMRI study on the brain activity induced by manual acupuncture at BL62(申脈). Methods: The study was the acupuncture at BL62(申脈) and we acquired 9 fMRI results from 6 persons$(age\;20{\sim}30,\;4\;male\;and\;2\;female)$. These studies employed The block design for mapping brain activity and acupuncture was perfomed at BL62(申脈) on the left foot. Results: The brain related motor function was cerebellum, basal ganglia and cerebral cortex and thalamus connected these elements. In the result of this study, the regions of significant activation in the cerebellum was centered on the spinocerebellum in the anterior lobe, so we presumed that this result showed the input of stimulation by the acupuncture on BL62(申脈). But basal ganglia and cerebral cortex showed the regions of significant activation in the left larger than the right and regions of the cerebral cortex was the motor and sensory cortex. Such a result explained that acupuncture at BL62(申脈) could have influence the motor function and acupuncture at left BL62(申脈) could affect the right side through the activation of the left basal ganglia and cerebral cortex. Conclusions: In the theory of crossing needling at collaterals(繆刺論), it the pathogenic factor invaded in the Yang Heel channel(陽?脈) that was one of the eight Extra meridians(奇經八脈), we recognized the disease of the collateral channel and used contralateral BL62(申脈) for treatment of the Yang Heel channel(陽?脈). Moreover the result of this study could bear the construction that acupuncture at the left BL62(申脈) treats the contralateral lesion and this construction is related to the theory of crossing needling at collaterals(繆刺論).

Objectives : This study aimed to investigate the general effects of low-frequency electrical stimulation of the ankle joint acupuncture points(BL62 and KI6) on the brain waves of elderly women as a pilot study to figure out the possibility of candidate non-invasive and non-chemical stimulation method for the enhancing the brain function. Methods : A randomized, controlled, double-blinded clinical trial was performed in 31 healthy women(mean age, 54.5 years) within a treatment duration of 12 sessions. In the experimental group, low-frequency electrical stimulation was applied using the maximum range of the individual insensible strength(mean current, $0.04{\mu}A$). The control group received sham stimulation. The background electroencephalographic activity was measured before and after the12 sessions. Results : After 12 sessions of stimulation, the relative power of the alpha wave increased(32 of 32 channels: significant difference in 11 channels, p<0.05); the theta(30 of 32 channels: significant difference in 10 channels, p<0.05), beta(31 of 32 channels), and gamma(30 of 32 channels: significant difference in 7 channels, p<0.05) powers were also decreased compared with the sham group. Conclusions : Electrical stimulation on the ankle joint acupuncture points(BL62 and KI6) seemed to stabilize the elderly women brain by inducing the alpha power and reducing beta, theta, and gamma powers. These results provide insight into the action mechanism of the stimulation and can assist the future developement of a non-invasive and non-chemical treatment technique for stressor related cognitive problems.

The general and specific combining abilities and hybrid vigour of seven polyvoltine breeds [BL24, BL62, BL6S, BL67, BL68, BL69, and Pure Mysore (PM)] with five bivoltine breeds (NB4D2, CSR2, CSR5, CSR18 and CSR19) were evaluated in a line ${times}$ tester design by analysing six quantitative traits viz., fecundity, yield 110,000 larvae both by number and weight, cocoon weight, shell weight and cocoon shell ratio. ANOVA estimates showed significant effects for all the traits indicating the role of both additive and non- additive gene actions. Estimation of GCA revealed that the breed BL67 exhibited significant positive effects toy all the six traits followed by BL68 for four important economic traits viz., fecundity, cocoon weight, shell weight and cocoon shell ratio. Among testers, CSR5 showed significant GCA effects for five traits whereas CSR2 exhibited for shell weight and shell ratio. Three hybrids viz., BL67${times}$ NB4D2, BL67 ${times}$CSR5 and BL67${times}$ CSR19 excelled in four quantitative traits for SCA. Majority of the hybrids expressed positive hybrid vigour for cocoon yield/10,000 larvae by weight, cocoon weight and shell weight. Four hybrids namely PM ${times}$ NB4D2, BL67 ${times}$NB4D2, BL67${times}$ CSR5 and BL67${times}$ CSR19 manifesting positive hybrid vigour for five economic traits were adjudicated as best Heterotic hybrids and recommended for commercial exploitation to increase the silk yield.

More effective treatments are needed for non-alcoholic fatty liver disease (NAFLD). We hypothesized that water extracts of blackberry fruits (BF) and leaves (BL) and their combinations (BFL) reduce fat deposition in HepG2 cells and modulate shor-tchain fatty acids (SCFA) and fecal bacteria in vitro. HepG2 cells were treated with BF, BL, BFL1:2, and BFL1:3 for 1 h, and 0.5 mM palmitate was added to the cells. Moreover, low ($30{\mu}g/mL$) and high doses ($90{\mu}g/mL$) of BL and BF were applied to fecal bacteria in vitro, and SCFA was measured by GC. BL, BF, BFL1:2, and BFL1:3 reduced triglyceride deposition in the cells in a dose-dependent manner, and BFL1:2 and BFL1:3 had a stronger effect than BF. The content of malondialdehyde, an index of oxidative stress, was also reduced in BL, BF, and BFL1:2 with increasing superoxide dismutase and glutathione peroxidase activities. The mRNA expression of acetyl CoA carboxylase, fatty acid synthase, and sterol regulatory element-binding protein-1c was reduced in BL, BF, BFL1:2, and BFL1:3 compared to the control, and BFL1:2 had the strongest effect. By contrast, the carnitine palmitolytransferase-1expression, a regulator of fatty acid oxidation, increased mostly in BFL1:2 and BFL1:3. Tumor necrosis factor-${\alpha}$ and interleukin-$1{\beta}$ expression was reduced in BL compared to that in BF and BFL1:2 in HepG2 cells. Interestingly, BL increased propionate production, and BF increased butyrate and propionate production and increased total SCFA content in fecal incubation. BF increased the contents of Bifidobacteriales and Lactobacillales and decreased those of Clostridiales, whereas BL elevated the contents of Bacteroidales and decreased those of Enterobacteriales. In conclusion, BFL1:2 and BFL1:3 may be potential therapeutic candidates for NAFLD.

Penicillin G amidase (PGA, benzylpenicillinaminohydrolase, EC 3.5.1.11) is industrially important enzyme which converts penicillin G to 6-aminopenicillanic acid (6-APA) and phenylacetic acid (PAA). The PGA in E. coli ATCC 11105 is secreted into the periplasm after removing signal sequences and becomes heterodimer which composed of two subunits, small subunit (24 kDa) and large subunit (65 kDa). In this study, the PGA gene was obtained from E. coli ATCC 11105 using PCR (polymerase chain reaction) technique. The active PGA was successfully secreated into periplasm in E. coli BL2 1(DE3) harboring pET-pga plasmid. The optimized fed-batch fermentation, consisting of a three-step shift of culture temperature from $37^{\circ}C$ to $22^{\circ}C$, gave a productivity of 19.6 U/mL with a cell growth of 62 O.D. at 600 nm.
