  • Objectives : The purpose of this study was to investigate the effects of warm needling at $GB_{30}{\cdot}GB_{34}$ on Complete Freund's Adjuvant(CFA)-induced rheumatoid arthritis in rats. Methods : Arthritis was induced by injecting CFA subcutaneously into the left knee joint and paw. Acupuncture(AT) and warm needling(W-AT0.5, W-AT1.0) were injected at $GB_{30}{\cdot}GB_{34}$, every other day for a total of 5 times beginning on day 10 after the CFA injection. Thereafter, external shape, paw edema, serum aminotransferase and anti-inflammatory factors were assessed, and hematological and histological observations were made. Results : In paw edema volume all 3 groups(AT, W-AT0.5, W-AT1.0) showed significant decrease compared to the CFA control group. In TNF-${\alpha}$ and IL-6, all 3 groups showed significant decrease compared to CFA control group. In AST and ALT all 3 groups showed no significant change. In IL-$1{\beta}$, W-AT0.5 and W-AT1.0, groups showed significant decrease compared to the CFA control group. Leucocyte, erythrocyte and thrombocyte, all 3 groups showed no significant change. In histological observations, all 3 groups were similar to the intact group in terms of synoviocyte, cartilage lacuna and cartilage cells. Conclusions : The results suggest that warm needling at $GB_{30}{\cdot}GB_{34}$, has the effect of suppressing inflammation of CFA-induced rheumatoid arthritis in rats.

  • Objectives The aim of this study was to investigate the effects of Cannabis Fructus on exercise capacity and cognitive function in chronic hypoperfusion induced vascular dementia rat model. Methods Vascular dementia rat models were induced by chronic cerebral hypoperfusion through bilateral common carotid arteries occlusion (BCCAO). All rats were randomly divided into 4 groups: normal group; control group; CF I group (feeding Cannabis Fructus 100 mg/kg); CF II group (feeding Cannabis Fructus 300 mg/kg). In order to study the effects of oral administration of Cannabis Fructus on vascular dementia rat models, corner turn test, hole board test, radial arm maze test, passive avoidance test were taken and Acetylcholine (ACh) activity, Acetylcholinesterase (AChE) activity, serum of Vascular endothelial growth factor (VEGF) protein level were measured. Also histological findings of the liver, kidney, brain and the change of Tau immunoreactive neurons in hippocampus were observed. Results CF I and CF II showed significant improvement in corner turn test, hole board test, radial arm maze test, passive avoidance test, Acetylcholine (ACh) activity, Acetylcholinesterase (AChE) activity, the serum of Vascular endothelial growth factor (VEGF) protein level and the change of Tau immunoreactive neurons in hippocampus. CF I showed more significant effect than CF II in these tests. However in histological observations of the liver and kidney both CF I and CF II showed glomerular injury and hepatotoxicity. Conclusions These results suggest that Cannabis Fructus was helpful in improving exercise capacity and cognitive function on Chronic hypoperfusion induced Vascular Dementia rats. However Cannabis Fructus affects the liver and kidney, therefore suggest that this is an area for further study.

  • The studies were attempted to evaluated the therapeutic effects of various fractions(ether, methanol, butanol) of Caragana chamlagu roots on the hyperlipemia induced by feeding the diet containing 1%, cholesterol and 0.5%, cholic acid in rats, and on the hyperglycemia induced by streptozotocin in rats. Also the preventive effects of these fractions were studies on the liver damage in $CCl_4-intoxicated$ rats. The followings were obtained as the results: 1.The butanol fraction was significantly shown to down the serum lipid level in 1%, cholesterol and 0.5%, cholic acid diet-feeding rats and streptozotocin-induced hyperglycemic rats. Cholesterol level in $CCl_4-intoxicated$ rats was reduced in the case of all pre-treated groups. 2.The serum glucose level of streptozotocin-induced hyperglycemic rats was significantly decreased by the administration of various fractions of C. chamlagu roots, and the lipid-peroxidation of pancreas was significantly decreased in the case of administration of these fractions. 3.The activates of s-GOT and s-GPT were decreased by the administration of various fractions, especially in butanol fraction, of C. chamlagu roots in the $CCl_4-intoxicated$ rats. The liver lipid-peroxidation was decreased by administration of 200mg/kg of these fractions in the $CCl_4-intoxicated$ rats. In histological observation, hepatic cellular necrosis and fatty acid deposit were increased remarkably by $CCl_4-intoxication$, but the pretreatment of various fractions of C. chamlagu roots improved the pathological change of parenchymatous cell necrosis and fatty change around centrilobular area of the control.

  • We reviewed sex-change patterns in the wrasses Halichoeres poecilopterus, H. tenuispinis, Pteragogus flagellifer, and Pseudolabrus sieboldi inhabiting the coastal waters of Jeju, Korea, based on the sex distribution according to standard length and sex characteristics of the gonads. Halichoeres poecilopterus, H. tenuispinis, Pt. flagellifer, and Ps. sieboldi are protogynous hermaphroditic fish. Histological observations revealed that these wrasses are undelimited type 2 species because testicular tissue(spermatogenesis area) appears in most parts of the gonads during ovary of degenerative stage. Both initial- and terminal-phase males were present in the investigated populations, indicating that Halichoeres poecilopterus, H. tenuispinis, and Ps. sieboldi are of the diandric type. In contrast, Pt. flagellifer is considered a monandric type, because all males in the investigated populations were terminal-phase males produced via sex change from functional females.

  • Purpose: The purpose of this study was to investigate the effects of implant collar design on marginal bone change and soft tissue response by an animal test. Materials and methods: Two types of Implant (Neobiotech Co. Seoul, Korea) that only differs in collar design were planted on two healthy Beagle dogs. The implants were divided into two groups, the first group with a beveled collar (Bevel Group) and the second group with "S" shaped collar (Bioseal group). Standardized intraoral radiographs were used to investigate the mesio-distal change of the marginal bone. Histological analysis was done to evaluate the bucco-lingual marginal bone resorption and the soft tissue response adjacent to the implant. Mann-Whitney test was done to compare the mesio-distal marginal bone change at equivalent time for taking the radiographs and the tissue measurements between the groups. Results: Radiographic and histological analysis showed that there was no difference in marginal bone change between the two groups (P>.05). Histological analysis showed Bioseal group had more rigid connective tissue attachment than the Bevel group. There was no difference in biological width (P>.05). Bevel group showed significantly longer junctional epithelium attachment and Bioseal group showed longer connective tissue attachment (P<.05). Conclusion: For three months there were no differences in marginal bone change between the Bevel group and the Bioseal group. As for the soft tissue adjacent to the implant, Bioseal group showed longer connective tissue attachment while showing shorter junctional epithelium attachment. There were no differences in biologic width.

  • Rockfish, Sebastes schlegeli (total length; $10.36{\pm}0.49cm$, total weight; $16.28{\pm}1.86g$, N; 290) were exposed to various concentrations of naphthalene for 28 days. Exposure concentrations of naphthalene established control, ethanol (solvent) control, 0.5, 1.0, 1.5 and 2.0 mg Nap $L^{-1}$. After exposure, We observed survival rate, and degree of tissue change (DTC) in gill under optical microscopy. Survival rate of the rockfish was more than 90% in control, ethanol control, 0.5 and 1.0 mg Nap $L^{-1}$, whereas it decreased in 1.5 and 2.0 mg Nap $L^{-1}$ (respectively 80%, 62.2%). In histological observation of gill, hyperplasia of epithelial cells observed in all exposure groups. But no showed increase of DTC which was related to concentration. Whereas, DTC at fusion of gill lamellar, lamellar telangiectasia, stasis, aneurysm and necrosis showed dose dependent increase. Especially, fusion of gill lamellar, lamellar telangiectasia and stasis observed at more 1.0 mg Nap $L^{-1}$, and aneurysm and necrosis at more 1.5 mg Nap $L^{-1}$. These results showed naphthalene caused survival and severe change to the gill of the rockfish which was related to exposure concentration.
