  • 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).

  • 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, benzylpenicillinamidohydrolase, EC 3.5.1.11)는 penicillin G를 phenylacetic acid(PAA)와 6-aminopenicillanic acid(6-APA)로 분해하는 효소이다. Escherichia coli(E. coli) ATCC 11105의 PGA는 24 kDa의 small subunit과 65 kDa의 large subunit으로 구성되어 있고, precursor polypeptide에서 signal peptide와 spacer peptide가 절단되어 활성을 가진 heterodimer가 형성된다. 본 연구에서는 E. coli ATCC 11105에서 PCR(polymerase chain reaction)을 통해 증폭한 pga gene을 expression vector에 넣어 pET-pga plasmid를 제작하였고, 이것을 E. coli BL21 (DE3) 균주에 형질 전환하여 PGA를 발현하고 그 활성을 분석하였다. E. coli BL21(DE3)/pET-pga 균주의 고밀도 배양액을 SDS-PAGE로 분석 했을 때, PGA의 precursor, large subunit, 그리고 small subunit으로 보이는 protein band가 나타났으며, PGA가 soluble form의 precursor로 발현되어 processing을 거쳐서 large subunit과 small subunit으로 절단되기도 하고, 일부는 insoluble form의 precursor로 발현되기도 하는 것으로 생각된다. 유가배양시 온도변화 전략을 사용하여 고농도 배양에서 발현을 유도하였다. 온도변화 전략은 $37^{\circ}C$에서 $28^{\circ}C$를 거쳐 $22^{\circ}C$로 3단계로 변화시켰다. 이러한 전략으로 PGA활성은 19.6 U/mL이며 균체량은 600 nm에서 흡광도가 62까지 도달하였다.
