Objectives: The study was designed to evaluate anti-arthritic activity of Ajmodadi Churna (AC) and its effect on Complete freund's adjuvant (CFA)-induced arthritis in Wistar rats. Methods: Arthritis was induced by injecting 0.2 mL CFA into sub plantar surface of left hind paw. Test sample AC-1 and AC-2, 200 and 400 mg/kg, respectively was given to the animals for 21 consecutive days. The increase in swelling was observed after induction of arthritis. The paw edema was measured on 0, 3, 7, 14 and 21 day using Vernier caliper after the induction of arthritis. The collected blood samples further used for the estimation of red blood cells (RBC), white blood cells (WBC), erythrocytes sedimentation rate (ESR), and hemoglobin (Hb), using hematology analyzer. Serum concentration of IL-6 and TNF-α were also measured using rat ELISA kits. Results: Results showed that a significant reduction in paw edema was observed in AC-2 treated rats. The paw edema was restored on day 21 was 4.48 mm for AC-2, which is near to the control group. The arthritis score in treated rats was found to be considerably lower than in the control group i.e. 0.83 for AC-2 and 1.50 for AC-1. A decrease in levels of RBC and hemoglobin were observed in arthritic rats. Inflammation was significantly reduced and serum levels of IL-6 and TNF-α were lowered after treatment with the test drug. Conclusion: It can be concluded from the study that AC possess significant anti-arthritic activity. Furthermore, this condition was linked to a reduction in abnormal humoral immune responses.

To investigate the anti-inflammatory and analgesic effects of Herba Chelidoniie, the extracts of Herba Chelidoniie treated in arthritic rat model. Complete Freund,s Adjuvant(CFA) were injected in the subcutaneous tissue of left foot paw of rats to induce arthritis. Herba Chelidonii extracts(HC) was administered immediately into the peritoneal cavity after CFA injection for 12 days. The immunohistochemical stainings for calcitonin gene-related peptide(CGRP) and substance P in the L4, L5 and L6 spinal dorsal horn and ganglia were done, and the paw swelling was measured with a micrometer and the blood leukocytes were counted. The results were as follows : The paw swelling of HC treated group was significantly decreased in 12th day after CFA injection compare to control group. The change of differential leukocytes counts of HC treated group increased the ratio of lymphocytes, and decreased the ratio of neutrophils compare to control group. The extent of CGRP immunoreactive nerve fiber of dorsal horn of HC treated group was weakly stained compare to control group. The number of CGRP immunoreactive neurons of L6 spinal cord of HC treated group was significantly decreased compare to control group. The extent of substance P immunoreactive nerve fiber of dorsal horn of He treated group was weakly stained compare to control group. The number of substance P immunoreactive neurons of L4, L5 and L6 spinal cord of HC treated group was significantly decreased compare to control group. These experimental results suggest that Herba Chelidonii extracts reduce the number of CGRP and substance P immunoreactive neurons and nerve fibers of spinal dorsal horns and ganglia, and decrease paw swelling in arthritic rat model, which may be closely related to analgesic and antiinflammatory effects of Herba Chelidonii.

This study was conducted to evaluate the safety of a recombinant human Factor VIII(GC-$\gamma$ AHF) manufactured by Korea Green Cross Company with different technology according to the Regulation of Korean Food and Drug Administration (l 998. 12. 3). In acute toxicity test, both genders of Sprague-Dawley rats and Beagle dogs were administered intravenously with GC-$\gamma$ AHF of three doses (3,125, 625 and 125 IU/kg), and single dose of 3,125 IU/kg, respectively. No dead animal and abnormal autopsy findings were found in Control and GC-$\gamma$ AHF treated group. Therefore, the 50% lethal dose ($LD_{50}$) of GC-$\gamma$ AHF was conidered to be higher than 3,125 IU/kg in rats and dogs. In the four weeks repeated intravenous toxicity study, GC-$\gamma$ AHF was administrated intravenosly to both genders of rats and dogs with 3 doses (500, 150, 50 IU/kg). There were neither dead animals nor significant changes of body weights during the experimental Period. In addition, no significant GC-$\gamma$ AHF related changes were found in clinical sign, urinalysis and other finding. Statistically changes were observed in hematological, biochemical and organ weight parameters of treated groups: however these changes were not dose dependent. No histopathological lesion were observed in both control and treated animals. Above data suggest that no observed adverse effect level of test materials in rats and dogs might be over 500 IU/kg/day in this study. In ocular irritation test, any injury on iris, conjunctiva and cornea in rabbits were not observed. The acute ocular irritation index (A.O.I.), mean ocular irritation index (M.O.I.) and Day-7 individual ocular irritation Index (I.O.I.) of GC-$\gamma$ AHF were 0. In the primary skin Irritation test, the primary irritation index (P.I.I.) oj GC-$\gamma$ AHF were 0. Therefore, the GC-$\gamma$ AHF is considered not to have the primary skin and eye toxicity in rabbits. In active systemic anaphylaxis (ASA) test, GC-$\gamma$ AHF and GC-$\gamma$ AHF emulsified with Freund's complete adjuvant (FCA) did not induce any symptom of anaphylactic shock in guinea pigs. In passive cutaneous anaphylxis (PCA) test, after sensitization with antisera of GC-$\gamma$ AHF sensitized mice, blue spots were observed on the hypodermis of back of rats, but diameter of each spot was smaller than 5 mm in each test groups except the positive control group. Based on the results of this study, GC-$\gamma$ AHF is not conidered to have any antigenic potential. In conclusion, at levels of up to 500 IU/kg, GC-$\gamma$ AHF did not produce treatment-related toxicity under the conditions of these acute-, four week repeated-toxicity, primary skin and eye toxicity, and antigenicity test.

Background: CC chemokine receptor (CCR) 7 and cognate CCR7 ligands, CCL21 (formerly secondary lymphoid tissue chemokine [SLC]) and CCL19 (formerly Epstein-Barr virus-induced molecule 1 ligand chemokine [ELC]), were known to establish microenvironment for the initiation of immune responses in secondary lymphoid tissue. As described previously, coadministration of DNA vaccine with CCR7 ligand-encoding plasmid DNA elicited enhanced humoral and cellular immunity via increasing the number of dendritic cells (DC) in secondary lymphoid tissue. The author hypothesized here that CCR7 ligand DNA could effectively expand memory CD4+ T cells to protect from viral infection likely via increasing DC number. Methods: To evaluate the effect of CCR7 ligand DNA on the expansion of memory CD4+ T cells, DO11.10.BALB/c transgenic (Tg)-mice, which have highly frequent ovalbumin $(OVA)_{323-339}$ peptide-specific CD4+ T cells, were used. Tg-mice were previously injected with CCR7 ligand DNA, then immunized with $OVA_{323-339}$ peptide plus complete Freund's adjuvant. Subsequently, memory CD4+ T cells in peripheral blood lymphocytes (PBL) were analyzed by FACS analysis for memory phenotype ($CD44^{high}$ and CD62 $L^{low}$) at memory stage. Memory CD4+ T cells recruited into inflammatory site induced with OVA-expressing virus were also analyzed. Finally, the protective efficacy against viral infection was evaluated. Results: CCR7 ligand DNA-treated Tg-mice showed more expanded $CD44^{high}$ memory CD4+ T cells in PBL than control vector-treated animals. The increased number of memory CD4+ T cells recruited into inflammatory site was also observed in CCR7 ligand DNA-treated Tg-mice. Such effectively expanded memory CD4+ T cell population increased the protective immunity against virulent viral infection. Conclusion: These results document that CCR7 and its cognate ligands play an important role in intracellular infection through establishing optimal memory T cell. Moreover, CCR7 ligand could be useful as modulator in DNA vaccination against viral infection as well as cancer.

목적 : 본 연구는 (a) 저빈도 전침의 만성 단발성 관절염에 대한 치료 효과와 (b) 척수에서 동통과 관련되는 지표인 P 물질과 trk A mRNA의 발현조절에 미치는 영향을 연구하기 위해 실행되었다. 방법 : Complete Freund's adjuvant를 실험동물의 우측 경족근관절에 주입하여 관절염을 유발시키고 9주 동안 관찰하였다. 만성 관절염의 최적의 치료조건을 찾기 위하여 각각 세 종류의 경혈(환도, 용천, 족삼리)과 전침자극강도(0.5, 1, 2 mA)를 사용하여, 행동학적 지표로서 동통을 측정하였다. 측정 결과 가장 큰 효과를 나타낸 군을 선택하여 RT-PCR 방법을 사용하여 P 물질 및 trk A mRNA의 변화를 척수 후각과 후근신경절에서 측정하였다. 결과 : 관절의 굴신을 통한 통증 검사와 족과관절 둘레 길이 측정을 통하여 관찰한 결과 원위부에 위치한 환도에 저강도의 자극을 시행한 경우(환도, 0.5 mA)가 가장 우수한 치료 효과를 나타내었다. RT-PCR을 시행한 결과, 환측 후근신경절의 P물질이 관절염 유발 대조군의 경우 정상군에 비해 증가하였고 환도-0.5mA 군에서 다시 감소하는 것을 관찰하였으며, trk A는 관절염 유발군의 경우 척수 후각에서 양측성 증가를 나타내었고 이는 전침치료에 의해 다시 감소되는 것을 관찰하였다. 결론 : 환도 0.5mA의 저빈도 전침은 관절염을 효과적으로 감소시킬 뿐 아니라 관절염으로 증가된 후근신경절의 P 물질과 척수후각의 trk A mRNA 발현을 효과적으로 감소시켰으며, 이는 원위취혈로 선혈된 환도혈의 만성관절염에 대한 치료효과를 분명히 보여준다고 할 수 있다.

이상의 실험결과들을 요약하면, CFA를 안면영역 피하로 주입하여 발생한 염증성 통증 행위반응은 P2X 수용체의 억제제의 투여로 감소할 수 있었다. 특히 $P2X_7$ 수용체 억제제를 투여하면 진통작용 뿐 아니라 활성화된 신경아교세포 발현을 억제하였다. 이러한 실험 결과는 $P2X_7$ 수용체가 신경아교세포에 영향을 미쳐 안면에서 발생하는 만성 염증성 통증의 발생과 유지에 관여하고 있다는 것을 보여준다. 따라서 중추신경계의 신경아교세포를 조절할 수 있는 중추성 $P2X_7$ 수용체 작용기전은 임상에서 만성 염증성 통증을 보다 효과적으로 치료할 수 있는 새로운 방법을 제시해 줄 수 있다고 생각된다.

치아우식증을 예방하기 위한 백신연구를 위하여 주원인균인 Sterptococcus mutans 균체항원과 이 균에서 분리한 glucosyltransferase (GTF)를 항원으로 하고 이에 면역조절기능이 있는 retinoic acid (RA)를 첨가하여 투여경로와 백신조성이 이들 항원에 대한 면역반응에 미치는 영향을 실험하였다. 균체항원(Ingbritt strain)을 마우스의 피하에 Complete Freund's Adjuvant와 함께 투여하여 생산되는 혈청내 응집항체가는 serotype e (LM-7)와는 강한 교차반응을 보였으나 serotype f (OMZ-175)와는 거의 교차반응을 일으키지 않았다. 면역혈청내 항-GTF 및 항-Ag I/II 항체중 항-GTF IgA는 피하로 투여시 전혀 검출되지 않았으나 이에 RA를 첨가하면 다량의 항체 생산을 관찰하였고 그 정도는 경구투여시의 생산량을 능가하였다. GTF를 alum과 함께 투여하여 생산되는 혈청내 항-GTF 항체중 IgM은 피하로 투여시 상당량이 검출되었고 RA를 첨가하면 그 생산이 증가되었으며 경구로 투여시 대조군에 비하여 약간증가를 보였으나 피하투여시의 그것에는 미치지 못하였다. GTF-특이 IgG는 경구투여시는 전혀 검출되지 아니하였고, 피하투여시에만 현저한 증가를 보였으며, RA첨가는 이에 영향을 미치지 못하였다. 항-GTF IgA는 피하로 투여시 전혀 검출되지 아니하였으나 이에 RA를 첨가하면 증가된 항체생산을 관찰하였고 그 정도는 경구투여시의 생산량을 능가하였다. 이상의 실험성적은 GTF에 대한 항체생산은 투여경로와 항원의 종류에 따라 다양한 반응을 나타내며 RA는 이를 백신에 첨가하면 피하경로를 이용하여 면역하더라도 경구투여와 유사한 IgA-매개 면역반응으로 조절시킬 수 있는 가능성을 나타내었다.

The present study aims to investigate a possible mechanism of electroacupuncture (EA) in the spinal dorsal horn that may underlie N-methyl-D-aspartate (NMDA) receptor-associated extracellular signal-regulated kinase (ERK) mitogen-activated protein kinase (MAPK) signaling pathways. The hot plate latency of the ipsilateral hindpaw of EA-treated rats was significantly decreased compared with complete Freund's adjuvant (CFA)-injected ones. The expressions of NR1 and NR2B subuint mRNA of NMDA receptor in the whole L4-5 segments are decreased by CFA treatment, but NR2B subunit was significantly recovered by EA treatment. When we detected the expression of ERK, there were no significant difference between normal and CFA-treated rats with EA or NMDA receptor antagonist MK801. But phosphorylated ERK expressions were markedly induced by CFA, but these inductions were significantly modulated by EA treatment. Although hosphorylation of ERK was also arrested by MK801, these inductions of CFA-injected rats was markedly inhibited only by co-treatment with EA and MK801. Phosphorylated cAMP response element-binding protein (CREB), ERK-related transcriptional factor, showed a significant increase in CFA-treated rats and this increase was slightly inhibited by EA and MK801 treatments. But immunoreaction for phosphorylated CREB were significantly increased by CFA treatment in the superficial laminae of the dorsal horn and these inductions were significantly arrested by co-treatment of EA and MK801. Consequently, the hyperalgesia induced by CFA are associated NMDA receptor and EA and MK801 may showed anti-hyperalgesia via same mechanism for inhibition of ERK and CREB phosphorylation in the dorsal horn.
