To investigate effects of Taraxaci herbal-acupuncture on Adjuvant Arthritis in rats, the edema rate, the number of WBC, the quantity of total protein, albumin and globulin in the blood serum and histological test of the muscular tissue were measured in the arthritis part. 1. After elicitating arthritis of Sprague Dawely(SD) rats by injection of Freund's complets adjuvant for 2 weeks, saline was injected for the Exp. I group and Taraxaci herbal-acupuncture was injected for the Exp. II group during 30days. Selected point was $ST_{35}$ in both the groups. And then the volume of the paw were checked. The volume of paw was $0.84{\pm}0.14mm$ in the Exp. I group and $0.38{\pm}0.17mm$ in the Exp. II group, the swelling of the paw was restricted significantly in the Exp. II group(p<0.05) 2. The number of WBC was $10.34{\pm}0.14(10^3/ml)$ in the normal group and $37.47{\pm}5.46(10^3/ml)$ in the Exp. I group. It was $20.39{\pm}4.23(10^3/ml)$ in the Exp. II group. This fact showed that the group Exp. II was more effective than the Exp. I group in the treatment of arthritis(p<0.05) 3. The content of the total protein in the blood serum was $6.14{\pm}0.43g/dl$ in the normal group, $7.95{\pm}0.94g/dl$ in the Exp. I group, and $6.38{\pm}1.75g/dl$ in the Exp. II group. This fact showed that the group Exp. II was more effective than the Exp. I group in the treatment of arthritis(p<0.05) 4. The contents of albumin in the blood serum was $2.94{\pm}0.13g/dl$ in the normal group, $2.01{\pm}0.48g/dl$ in the Exp. I group. and $2.71{\pm}0.34g/dl$ in the Exp. II group. This fact showed that the group Exp. II was more effective than the Exp. I group in the treatment of arthritis(p<0.05) 5. The contents of globulin in the blood serum was $3.19{\pm}0.48g/dl$ in the normal group, $4.70{\pm}1.26g/dl$ in the Exp. I group. and $3.67{\pm}0.56g/dl$ in the Exp. II group. There was no significance in the serum globulin between Exp. II group and Exp. I group from the stastical analysis 6. In histological finding, because of severe inflammatory reaction, remarkably irregular tissue and large amount of inflammatory cells were found in the Exp. I group. But the Exp. II group showed small amount of inflammatory cells, the refrained inflammatory state and even recovering state. From these results, it is showed Taraxaci herbal-acupuncture refrain inflammatory reaction and muscular tissue necrosis in SD rats paw were induced by Freund's complete adjuvant

Oxidative stress has been implicated in cutaneous damage in various inflammatory skin diseases, including atopic dermatitis (AD). Atoberry is the herb medicine extract which is composed with Spirodelae Herba, Xanthii Fructus, Houttuyniae Herba, Taraxaci Herba, Retinervus Luffae Fructus, Platycodi Radix, and Scutellariae Radix. In this study, we investigated the antioxidant and anti-inflammatory effects of Atoberry in AD-like skin lesion NC/Nga mice. Murine AD-like skin lesions were made by painting Dermatophagoides farinse (Df) extract. Atoberry significantly increased electron donating ability (DPPH), nitrite scavenging (NO) and superoxide dismutase (SOD) activities in dose dependant. Topically applied Atoberry significantly reduced clinical severity score, ear thickness and histological grade in AD-like skin lesion NC/Nga mice. In addition, the serum levels of IgE, NO and prostaglandin E2 were significantly reduced by Atoberry. Futhermore, skin tissue levels of SOD, catalase and glutathione peroxidase (GPx) were significantly reduced by Atoberry. These results demonstrate that topical application of Atoberry may be improve the AD-like skin lesion by antioxidant and anti-inflammatory effects.

Objectives : Taraxaci Herba et Radix (THR) is widely used as a food and medicinal herb in Korea. It has been used for treatment of virus inflammatory disease, liver diseases and gastritis. So far, anti-inflammatory effects and constituents of various species in THR has not been studied for comparison. The aim of this study is to compare the anti-inflammatory effects of the aerial part and root from various THR. Also, we have compared the contents of its known constituents with each. Methods : In this study, we estimated anti-inflammatory effect and compared their constituent by HPLC. For the determination of anti-inflammatory effects, we investigated NO and $PGE_2$ production by ELISA. The expressions of iNOS was determined by western blotting in LPS-induced RAW 264.7 macrophage cells. And, standard compounds which are methyl gallate, gallic acid, syringic acid and esculetin of THR were analyzed by HPLC using a $C_{18}$ column. Results : Methanol extracts of THR decreased NO and $PGE_2$ production. The expressions of iNOS protein were also decreased in methanol extracts of THR. As a result, HPLC analysis showed that they showed similar patterns. Methyl gallate and esculetin showed the highest content. Methyl gallate was included over 10% content in each aerial part and root of THR. Conclusions : These results indicate that most of THR distributed in Korea might represent therapeutic agent for treatment of inflammatory diseases.

According to herbalogical bibligraphy and literature, therapeutic effects of Achyranthis Radix on arthritis was as follows, 1. Achyranthis Radix of Amaranthaceae is divided into five species-Achyranthes japonica, A. bidentata, A. longifolia, A. fauriei, Cyathula capitata, C. officialis and the characteristic, taste, channel entry, effects and main treatments were alike. 2. Winefrying stood for repairing treatement method for Achyranthis Radix Before repairing treatment method, Achyranthis Radix had three tastes(bitter, sour, and sweet) and calm and not poisoning characteristic. After repairing treatment method, the bitter taste was disappeared, and calm and not poisoning characteristic was changed into warm characteristic. 3. Effects of Achyranthis Radix were quicking the blood and dispelling stasis, liver-kidney supplement and strengthening musculo-skeletal system. Main treatments were relief of lumbar and knee joint pain, static menstrural block and wind-cold- damp impediment. 4. Contraindication of Achyranthis Radix was sympthom caused by spleen-kidney yang vacuity, upper burner disease and lower burner hemorrhage etc. Being used in pregnant woman, it could incur abortion. 5. Contraindication of Achyranthis Radix was beef, milk and mutton. It's fear was Radix Cynanchi Stauntonii and Semen Plantaginis. It's aversion was the firefly. Herba Taraxaci, Carapax Amydae, Carapax Testudinis and Radix Cynanchi Stauntonii. From above results, I suppose Achyranthis Radix has enough herbalogical foundation and could be used to treat arthritis and it is necessary to make a profound study of it.
