9Objective : We carried out this experimental study in order to investigate the effect of Chaenomelis Fructus(木瓜) extract and herbal-acupuncture on the arthritis induced by injecting Freund's complete adjuvant Method : 1. We categorized SD-rats into five groups as followings. (1) Control: Without any Treat (2) Treat I: treated by acupuncture (3) Treat II: treated by drinking 5% saline (4) Treat III: treated by drinking Chaenomelis Fructus(木瓜) extract (5) Treat IV: treated by Chaenomelis Fructus(木瓜) herbal-acupuncture 2. We established ten items for decision of experimental results as followings Edema rate, Pain endurance, WBC, Hemoglobin, Platelet, Total protein, Albumin, Globulin, RA factor, CRP Results : The groups that showed significant effects compared with Contol group were explained as followings. 1. Edema rate : Treat I , Treat III 2. Pain endurance : Treat I, Treat IV 3. WBC : Treat IV 4. Hemoglobin : Treat III 5. Plat99elet : Treat IV 6. Total protein : Treat I, Treat IV 7. Albumin : None 8. Globulin : Treat I, Treat IV 9. RA factor : Treat I, Treat IV 10. CRP : Treat IV Conclusion : Observing above experimental results, we can guess that the effects of acupuncture and Chaenomelis Fructus(木瓜) herbal-acupuncture on Freund's adjuvant arthritis are more superior than other ways. In addition, we can find that the latter is more better than the former in effect by two items(platelet, CRP).

Background: Effect of nitric oxide on the hyperalgesia induced by inflammation is controversial. We attempted to find out the peripheral effects of nitric oxide (NO) on hyperalgesia induced by Freund's complete adjuvant (FCA) induced inflammation. Methods: Male Sprague Dawley rats were divided into three groups; control, low dose NG-nitro-L-arginine methyl ester (L-NAME, 500 ug), high dose L-NAME (5 mg). Inflammation was induced by injecting 0.1 ml of FCA intraplantarly, which shows typical hyperalgesia within twelve hours after injection and maintained for about one week. Drugs were injected 2 hours before, just before, and 3, 6, 9, 12 hours after the injection of FCA. Effect of L-NAME on hyperalgesia was assessed by measuring mechanical hyperalgesia and spontaneous pain for 3 days. Results: When injected at the site of inflammation, L-NAME caused dose dependent reduction of spontaneous hyperalgesia. Mechanical hyperalgesia was also reduced by high dose L-NAME (p<0.05). After systemic injection of high dose L-NAME in the back, no significant difference was noticed. Conclusions: This suggest that L-NAME reduces FCA induced hyperalgesia via peripheral action.

Objectives : The purpose of this study is to investigate the effect of $Clematidis$ radix herbal-acupuncture solution, on collagen, adjuvant, lipopolysaccharide and phospholipase A2 induced rheumatoid arthritis in mice. Methods : Arthritis index was measured for mouse that was injected subcutaneously in solution mixed chicken type II collagen with Freund's complete adjuvant. We injected Freund's complete adjuvant into right posterior part of the sole of a ICR mouse foot, which was measured by plethysmometer. The solution mixed $CRHS$ with Tris-HCI, $CaCl_2$, substrate, enzyme was done a chemical action for thirty minutes, and then inhibitory activity of PLA2 enzyme was expressed with inhibition percentage by utilizing isolated arachidonic acid. COX-2 was induced by adding LPS to RAW 264.7 cell, and COX-2 activity was measured by western blot analysis and $PGE_2$ Biotrak kit. Results : $CRHS$ also inhibited Freund's complete adjuvant induced chronic rheumatoid arthritis in mice. $CRHS$ showed significant inhibition of type I and type II $PLA_2$ activities in a dose dependent manner. Furthermore, $PGE_2$ production was decreased with $CRHS$ and lipopolysaccharide-induced COX-2 protein expression was significantly inhibited by $CRHS$. Conclusions : These results suggest that $CRHS$ has an therapeutic effect on drug induced-rheumatoic arthritis by inhibiting $PLA_2$ and COX-2 activities.

This study was designed to determine the effects of swimming and low power laser on rheumatoid arthritis in Sprague-Dawley rats. Rheumatoid arthritis was induced in 36 rats among 48 Sprague-Dawley rats by the subcutaneous injection of .05 $m{\ell}$ Freund's Complete Adjuvant into the right hind paw and .05 $m{\ell}$ Freund's Complete Adjuvant into the right hind knee joint capsule. A second injection was performed by the same method using .1 $m{\ell}$ Freund's Complete Adjuvant per a rat. Arthritic rats were divided into 8 groups: each 1 week and 2 weeks of arthritic swimming, arthritic laser, arthritic case control and normal group. In this study, several experimental tests were performed to determine the concentration of Interleukin-6, the space of the knee joint and the thickness of the hind paw. The concentration of Interleukin-6 and hind paw thickness decreased in the swimming group and laser group as compared to the control group. The space of the knee joint increased significantly after the swimming exercise. Swimming and low power laser therapy positively affect rheumatoid arthritis in rats affect by decreasing the concentration of Interleukin-6 and hind paw thickness, and increasing the space of the knee joint.

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.

We consider a life testing experiment in which several two-component shared parallel systems are put on test, and the test is terminated at a predesigned experiment time. The bivariate data obtained from such a system-level life testing can be classified into three cases: 1) the case of failed two components with known failures times, 2) the case of censored two components, and 3) the case of one censored component and the other failed component of which the failure time might be known or unknown. In this thesis, the likelihood estimators for Freund's bivariate exponential life distribution under above censoring scheme are obtained. Results of comparative studies based on Monte Carlo simulation are presented.

Anti-inflammatory, anti-arthritic and analgesic activity of each herbal extract, which is extracted from Bacopa monnieriis, Cassia fistula and Phyllanthus polyphyllus, respectively. The treatment of herbal extract exhibited anti-inflammatory effect as a dose-dependent manner, from 1.25 mg/kg to 12.5 mg/kg, in acute inflammatory models (carrageen and egg-albumin induced rat hind paw edema). It also elicited significant anti-inflammatory activity in chronic inflammatory models (cotton pellet granuloma and Freund's adjuvant induced polyarthritis in rat). In cotton pellet granuloma test, the extract exhibited the inhibitory effect of 23 and 57% at the dose of 6.25 and 12.5 mg/kg, respectively. In Freund's adjuvant induced model, the treatment of the extract of 1.25, 6.25 and 12.5 mg/kg showed the inhibitory effect of 23, 56 and 66% at 8 days, respectively. In the acetic acid-induced model, the extract significantly reduced abdominal writhing in mice when compared to the control group, reducing the mean number of writhing from $41{\pm}2$ in the control group to $17{\pm}3$ and $15{\pm}2$ at the dose of 6.25 and 12.5 mg/kg. From these experiments, the extract, which was extracted from the combination of Bacopa monnieriis, Cassia fistula and Phyllanthus polyphyllus, (w/w/w = 1/2/1) is surprisingly found a significant analgesic and anti-inflammatory activity.
