  • This study was carried out to investigate the effects of enzyme activities on male Sprague-Dawley rats intoxicated by CCI4 on IS(Godulbaegi) diets for 4 weeks. We divides into 5 diet groups which were normal diet(N), normal diet intoxicated by CCI4(NC) and 3 IS diets ; leaves diet(ILC), roots diet(IRC) and mixed diet of leaves and roots which were also injected by CCI4 3 times for 4 weeks. The activity of glutamic pyruvic transaminase(GPT) in serum in NC was higher than in N as we expected. The GPT activites and the values of malondial-dehyde(MDA) of IS groups were all lower than in NC, IC as lowest. The activity of superoxide dismutase(SOD) in NC was higher than in N and IS groups had values less than the values of N. Catalase showed similarity in results as above. The values of glutathione S-transferase(GST) and cytochrome P-450 in NC were lower than in N. IS groups had higher values than in NC. Godulbaegi might be important not only as one of the traditional Korean foods but also as therapeutic agent for hepatotoxicity and for shortening the recovery time in liver disease.

  • Effects of aqua-acupuncture with soshiho-tang at Kansu(BL_{18}$) and Tamsu(BL_{19}$) on the Glutamic Oxaloacetic Transaminase(GOT), Glutamic Pyruvic Transaminase(GPT), Lactic dehydrogenase(LDH) and blood pictures in rat with $CCI_4$ were determined. In the group with $CCI_4$ the activity of GOT, GPT and LDH showed a tendency to increase, however these values showed a tendency to decrease by the aqua-acupuncture with soshiho-tang throughout experimental days and these values were recovered to those of control group on the last experimental days. Counts of RBC and Hemoglobin showed a tendency to decrease in rat with $CCI_4$, however these decreased values were recovered by the aqua-acupuncture with soshiho-tang and on the last experimental days, these values were similar to those of control group. In the $CCI_4$ group, counts of WBC and the proportion of Lymphocytes showed a tendency to increase and the proportion of Neutrophils showed a tendency to decrease, however these values showed a rapid recovery by the aqua-acupuncture with soshiho-tang. In the meridian point of Kansu and Tamsu, the effects of aqua-acupuncture with soshiho-tang on recovery of liver function showed no difference. Results from this study indicate that the aqua-acupuncture with soshiho-tang can improve the liver function in rat with $CCI_4$.

  • In this paper we have evaluated the degree of performance improvement in Multi-Carrier CDMA system adopting CCI canceller against MUI under mobile channel coexisting MU which is a major interference degrading the performance of Multi-carrier CDMA system. As a result of analysis, BER performance was improved by adopting CCI canceller and it was found that the amount of performance improvement was largely increased as Eb/No became higher. As an example, in case that data service BER = 10$^{-5}$ must be achieved with $E_{b/}$ $N_{o}$ = 12 ㏈, 4 users could be supported without CCI canceller while 30 users could be supported with CCI canceller, Also, we found that performance improving effect of 5$\times$10$^{-3}$ in a point of view BER could be achieved by adopting CCI canceller with fixed $E_{b/}$ $N_{o}$. o/. o/.

  • An aqueous extract of oriental herbal composition named Onchengyeum and curcumin, an antioxidant isolated from turmeric (Curcuma Zonga L.) reduced hepatotoxicity induced by carbon tetrachloride ($CCI_4$). Improved liver function was observed by measuring the activities of aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), blood urea nitrogen (BUN), creatinine (CRE), total cholesterol (T-CHO), triglyceride (TG), low density lipoprotein cholesterol (LDL-CHO), high density lipoprotein cholesterol (HDL-CHO), total protein (TP), albumin (ALB) and total bilirubin (BIL) in serum. Hepatic parameters monitored were levels of cholesterol (CHO), triglyceride (TG), and malondialdehyde (MDA) and activities of cytochrome P450 (CYP), NADPH-CYP reductase, superoxide dismutase (SOD), catalase (CAT), glutathione (GSH), glutathione S-transferase (GST), glutathione reductase (GR), and glutathione peroxidase (GPx). The histopathological examination showed that the treatment of Onchengyeum and curcumin relieved the ballooning degeneration of hepatocytes which had been generated by $CCI_4$. The results suggested that hepatoprotective effects of Onchengyeum and curcumin possibly are due to their promising antioxidative activity.

  • Poly (styrene-b-methyl methacrylate) (PS-b-PMMA) was synthesized by free radical telomerization: the telomerization of styrene with $CCI_4$ by using AIBN as initiator followed by a second telomerization of methyl methacrylate using $CCI_3$ end group of the resulting polymer as the macrotelogen, with AIBN initiation, gave the styrene-methyl methacrylate block copolymer. The effects of the concentration of the macrotelogen, the concentration of monomer, the molecular weight of the macrotelogen, the reaction temperature and the concentration of the solvent on the formation of the block copolymer were investigated. Block copolymers containing up to 10 weight percent PMMA were obtained by adjusting the reaction conditions.

  • Effects of forced physical exercise on the CCl4 hepatotoxicity were examined in adult female rats. Rats were treated with CCl4 (2 mmol/kg, ip) and introduced into a cylindrical cage rotating at 9 rpm for 20 min/hr for 6 hr. Eighteen hr following the termination of exercise serum sorbitol dehydrogenase (SDH), glutamic oxaloacetic transaminase (GOT), glutamic pyruvic transaminase (GPT) activities and glucose-6-phosphatase activity were determined as parameters for hepatotoxicity. Physical exercise inhibited the $CCI_{4-}$induced increases in SDH, GOT, GPT activity, and glucose-6-phosphatase activity were determined as parameters for hepatotoxicity.

  • Background: Thrombospondin-4 (TSP4) upregulates in the spinal cord following peripheral nerve injury and contributes to the development of neuropathic pain (NP). We investigated the effects of cyanocobalamin alone or in combination with morphine on pain and the relationship between these effects and spinal TSP4 expression in neuropathic rats. Methods: NP was induced by chronic constriction injury (CCI) of the sciatic nerve. Cyanocobalamin (5 and 10 mg/kg/day) was administered 15 days before CCI and then for 4 and 14 postoperative days. Morphine (2.5 and 5 mg/kg/day) was administered only post-CCI. Combination treatment included cyanocobalamin and morphine, 10 and 5 mg/kg/day, respectively. All drugs were administered intraperitoneally. Nociceptive thresholds were detected by esthesiometer, analgesia meter, and plantar test, and TSP4 expression was assessed by western blotting and fluorescence immunohistochemistry. Results: CCI decreased nociceptive thresholds in all tests and induced TSP4 expression on the 4th postoperative day. The decrease in nociceptive thresholds persisted except for the plantar test, and the increased TSP4 expression reversed on the 14th postoperative day. Cyanocobalamin and low-dose morphine alone did not produce any antinociceptive effects. High-dose morphine improved the decreased nociceptive thresholds in the esthesiometer when administered alone but combined with cyanocobalamin in all tests. Cyanocobalamin and morphine significantly induced TSP4 expression when administered alone in both doses for 4 or 14 days. However, this increase was less when the two drugs are combined. Conclusions: The combination of cyanocobalamin and morphine is more effective in antinociception and partially decreased the induced TSP4 expression compared to the use of either drug alone.

  • The effect of three polyacetylene compounds. panaxydol. panaxynol and panaxytriol isolated from Korean ginseng on $CCI_4-induced$ lipid peroxidation in vitro and in vivo hepatic microsomal lipid peroxidation were investigated. Lipid peroxide levels both in serum and liver and serum enzyme (GOT. GPT. LDH) activities of normal or $CCI_4-treated$ mice and rats were also determined after administration of polyacetylenes. Hepatic microsomal cytochrome P-450 content and activities of aniline hydroxylase and aminopyrine demethylase were measured after treatment of polyacetylenes with or without carbon tetrachloride. As results. treatment with polyacetylenes to control mice did not influence the levels of lipid peroxides and serum enzyme activities while panaxynol did. Panaxynol itself inhibited liver lipid peroxidation in normal mice. Polyacetylene compounds protected hepatic lipid peroxidation and lowered serum lipid peroxide levels induced by $CCI_4$ Polyacetylenes prevented leakage of LDH to serum but elevated GOT and GPT levels caused by $CCI_4$ were not changed by polyacetylene pretreatment. $CCI_4$ caused losses in the content of cytochrome P-450 and activities of aniline hydroxylase and aminopyrine demethylase. When polyacetylenes were treated without $CCI_4$ panaxydol and panaxynol induced aniline hydroxylase and all three polyacetylenes induced aminopyrine demethylase. Cytochrome P-450 contents were not affected by polyacetylenes. In vitro hepatic microsomal lipid peroxidation was inhibited by polyacetylenes and $DL-{\alpha}-tocopherol$ in a concentration-dependent manner.

  • Background: The mechanism of peripheral axon transport in neuropathic pain is still unclear. Chemokine ligand 13 (CXCL13) and its receptor (C-X-C chemokine receptor type 5, CXCR5) as well as GABA transporter 1 (GAT-1) play an important role in the development of pain. The aim of this study was to explore the axonal transport of CXCL13/CXCR5 and GAT-1 with the aid of the analgesic effect of botulinum toxin type A (BTX-A) in rats. Methods: Chronic constriction injury (CCI) rat models were established. BTX-A was administered to rats through subcutaneous injection in the hind paw. The pain behaviors in CCI rats were measured by paw withdrawal threshold and paw withdrawal latencies. The levels of CXCL13/CXCR5 and GAT-1 were measured by western blots. Results: The subcutaneous injection of BTX-A relieved the mechanical allodynia and heat hyperalgesia induced by CCI surgery and reversed the overexpression of CXCL13/CXCR5 and GAT-1 in the spinal cord, dorsal root ganglia (DRG), sciatic nerve, and plantar skin in CCI rats. After 10 mmol/L colchicine blocked the axon transport of sciatic nerve, the inhibitory effect of BTX-A disappeared, and the levels of CXCL13/CXCR5 and GAT-1 in the spinal cord and DRG were reduced in CCI rats. Conclusions: BTX-A regulated the levels of CXCL13/CXCR5 and GAT-1 in the spine and DRG through axonal transport. Chemokines (such as CXCL13) may be transported from the injury site to the spine or DRG through axonal transport. Axon molecular transport may be a target to enhance pain management in neuropathic pain.
