  • Objectives : This research was performed to investigate the effects of Ukgansan pharmacopuncture(U-PA) of focal brain ischemia induced by middle cerebral artery occlusion(MCAO) in rats. Methods : The subjects were divided into 5 groups : A control group, acupuncture group, pharmacopuncture group U-PA1($2.571mg/250g/40{\mu}{\ell}$), pharmacopuncture group U-PA2($6.428mg/250g/40{\mu}{\ell}$), and pharmacopuncture group U-PA3($12.855mg/250g/40{\mu}{\ell}$). The focal brain ischemia was induced by intraluminal filament insertion into the middle cerebral artery. After 3 days of MCAO, Ukgansan(UGS) pharmacopuncture treatment was performed on the GB20, and the day after being treated with pharmacopuncture, the Morris water maze test was carried out by the assigned group. The series of processes were treated 6 times. Thereafter Bax, Bcl-2, Bax/Bcl-2 ratio, mGluR5, density of neuronal cell, and ChAT were measured. Results : The results were as follows. 1. The intensity of Bax significantly decreased in the U-PA1, U-PA2, U-PA3 groups. 2. The Bax/Bcl-2 ratio significantly decreased in the U-PA3 group compared with the control group. 3. The neuroprotective effect on the hippocampal CA1 significantly increased in the U-PA1, U-PA2, U-PA3 groups compared with the control group. 4. The density of ChAT in the hippocampal CA1 significantly increased in the U-PA1, U-PA2, U-PA3 groups compared with the control group. Conclusion : These results suggest that UGS pharmacopuncture may have anti-apoptotic and neuroprotective effects on focal cerebral ischemia caused by intraluminal filament insertion into the middle cerebral artery in rats.

  • Objectives : The purpose of this study is to examine the effects of laser acupuncture according to the wavelength(532 nm, 650 nm, 830 nm, 904 nm, and 1064 nm) at the acupoint of GB34 GB39 on neuropathic pain rat induced by tibial and sural nerve transection(TST). Methods : Neuropathic pain in rats was induced by tibial nerve and sural nerve transection. The rats were divided into the intact group, the TST control group, and the laser acupuncture therapy group. The laser acupuncture therapy groups were then divided into subgroups with 532 nm(L532), 650 nm(L650), 830 nm(L830), 904 nm(L904), and 1064 nm(L1064) laser acupuncture therapy. The acupoint of GB34 GB39 was selected, and laser acupuncture therapy was provided on both sides alternatively twice a week in a total of 6 sessions. Results : All the laser acupuncture groups showed a significant decrease in reaction time and force intensity. L532, L904, and L1064 groups showed a significant decrease in Bax, the L532 group showed a significant increase in Bcl-2, L532 and L1064 groups showed a significant decrease in the Bax/Bcl-2 ratio, and L532 and L650 groups showed a significant increase in mGluR5, as compared with the TST control group, among nerve tissue reaction. Conclusions : These results showed that laser acupuncture therapy at each of the wavelengths had some significance on neuropathic pain.

  • For the development of functional food and cosmetics using hot water extract of Muraenesox cinereus's skin, contents of vitamin, amino acid and element, and antioxidant activity were investigated. The results are shown as follows: among vitamins, A(0.21mg/100 g), C (78.12mg/100 g), $D_3$ (0.03 mg/100 g), E (1.97 mg/100 g) and Niacin (2.53mg/100 g) were detected, respectively.Mineral contents were an order of K > P > Na > Mg > Ca > Fe and Zn. Contents of total amino acids were an order of Pro > Gly > Arg > Glu > Phe > Ala. Especially, the sum of total amino acids was 27.17 mg/100 mL, which was about 4.0 fold higher than that of free amino acid. DPPH radical scavenging activity of hot water extract of M. cinereus's skin at 25 mg/mL was 63.5% and did not increase at above 50 mg/mL. Activities of antioxidant enzymes in the liver of ethanol-treated rats using hot water extract of M. cinereus's skin were investigated. Compared to control group, activities of ADH and GSH-px were decreased. In the case of CAT and SOD activity, they were increased. These results showed that the hot water extract of M. cinereus's skin can be applied to raw macterial for functional food and cosmetics.

  • Objectives : The purpose of this study was to investigate the analgesic effects of filiform acupuncture and laser acupuncture at the points of $TE_3{\cdot}GB_{41}$ in neuropathic pain induced rats. Methods : Neuropathic pain in rats was induced by partial resection of the tibial and sural nerves. Three weeks after the neuropathic surgery, each of the experimental groups(AT, LAT, AT + LAT and LAT + AT) was injected at the $TE_3{\cdot}GB_{41}$ twice per week for three weeks. Results : 1. All of the experimental groups(AT, LAT, AT + LAT and LAT + AT) showed a significant decrease in the plantar withdrawal response of allodynia and the thermal allodynia as compared with the control group. During the early phase, the AT and AT + LAT groups have been marked as more significant than the LAT + AT and LAT groups. 2. The expression of c-Fos significantly decreased in the LAT and LAT + AT groups as compared with the control group. 3. The LAT + AT group showed a significant decrease in Bax as compared with the control group. In each experimental groups(AT, LAT, AT + LAT and LAT + AT), Bcl-2 increased and Bax/Bcl-2 ratio decreased as compared with the control group. 4. The LAT, AT + LAT and LAT + AT groups showed a significant increase in mGluR5 as compared with the control group. Conclusions : These results represented that the filiform acupuncture and laser acupuncture at the $TE_3{\cdot}GB_{41}$ exerted anti-apoptotic and neuroprotective effects on the model of neuropathic pain, thereby suggesting that they should be available for decreasing mechanical allodynia.
