Ayurveda, an ancient System of Indian Medicine, has recommended a number of drugs from indigenous plant sources for the treatment of inflammation. To evaluate the anti-inflammatory and analgesic activities of methanol extract of Triphala were investigated in Wister albino rats and mice. The methanol extract of Triphala were found to encompass substantial anti-inflammatory effect in acute and sub-acute models and analgesic effect. Animal models of carrageenan induced edema and cotton pellet induced granuloma in albino rats were used. Extract of 200 mg/kg shows significantly reduced paw edema. Analgesics activity of Triphala with 200 mg/kg shown by significant reduction of writhing. These report shows to support the use methanol extract of Triphala in relieving inflammation and pain.

This study reports the analgesic, anti-inflammatory and membrane-stabilizing property of alcoholic extract of Ophiorrhiza nicobarica (ON), a wild herb, used as an anti-infective ethnomedicine of Nicobarese and Shompen tribes of Great Nicobar Island, India. We for the first time investigated the analgesic and antiinflammatory potential of this herb in acute, subacute and chronic model of inflammation in Swiss albino mice and Wistar albino rats, along with sheep RBC-induced sensitivity and membrane stabilization. The acetic acid induced writhing, tail flick and tail immersion tests are used as a model for evaluating analgesic activity; while the carrageenin-induced paw oedema was used as the model for acute inflammation, dextran-induced oedema as sub-acute and cotton-pellateinduced granuloma as chronic inflammatory model. The probable mode by which ON mediate its effect on inflammatory conditions was studied on sheep RBC-induced sensitivity and membrane stabilization. The in vitro results revealed that the ON extract possesses significant (P < 0.05) dose dependent analgesic and antiinflammatory activity at 200 and 300 mg/kg and its fractions at 50 mg/kg, p.o. respectively, compared to the control groups. However, the extract failed to exhibit membrane-stabilizing property as it unable to reduce the level of haemolysis of RBC exposed to hypotonic solution. The acute toxicity studies of ON extract in rats and mice revealed that the extract was nontoxic even up to 3.0 g/kg body weight of the animals, with a high safety profile. We have isolated ursolic acid, ${\beta}$-sitosterol and harmaline respectively, from the bioactive part of the extract. The results indicated that the O. nicobarica is indeed beneficial in primary health care, and suggest that its anti-inflammatory activity may not be related to membrane-stabilization.

Propolid (bee-glue), known as a folk medicine, is a lipo;hilic material found in honeybee hives. In the present study on the anti-inflammatory effect of Korean propolis, it was extracted with ethanol, and used as a test material. The $LD_{50}$ value with the oral administration of ethanolic extract of Korean propolis (EEKP) was higher than 2g/kg in mice. The oral administration of the propolis extract (100mg/kg) significantly inhibited the development of hind paw edema induced by carrageenin in rats. the oral pretreatment of the propolis extract markedly inhibited the increase in vascular permeability and the number of writhing induced by acetic acetic acid in mice. Propolis extract, 50 and 100 mg/kg p.o. per day for 7 days, produced a significant inhibitory effect on granuloma and exudate formation in rats. This inhibitory effect was enhanced with the concomitant use of prednisolone (2.5 mg/kg). These results suggest that Korean propolis apparently has a strong anti-inflammatory activity.

GCSB-5 is a purified extract from a mixture of 6 Oriental herbs (Ledebouriellae Radix, Achyranthis Radix, Acanthopanacis Cortex, Cibotii Rhizoma, Glycine Semen, and Eucommiae Cortex) that have been widely used for the treatment of inflammatory diseases in the East Asia. The aim of this study was to investigate the anti-inflammatory potential of GCSB-5. The animals used in this study were administered either vehicle or GCSB-5 (30, 100, 300, and 600 mg/kg) orally. The GCSB-5 significantly inhibited the increased of acetic acid-induced vascular permeability (30.9%-34.2% inhibition at 30-300 mg/kg). The swelling of the rat's hind paw induced by carrageenan was significantly inhibited by GCSB-5 in doses of 100, 300, and 600 mg/kg. Maximal inhibition (50.9%) was obtained with GCSB-5 at dose of 300 mg/kg. However, it did not have any anti-inflammatory action in the rheumatoid arthritis induced by Freund's complete adjuvant or in the granuloma induced by carrageenan. Our finding suggest that GCSB-5 has a anti-inflammatory activity.

In order to clarify the morphological changes in the mammary glands of cows affected with coliform (Escherichia coli) mastitis, histopathological observations were undertaken on the mastitis of the lactating rabbits which was experimentally induced with E. coli or its endotoxin isolated from cases of acute and chronic matitis in dairy cattle. In the bacterial suspension-infused groups the affected quarters of udder showed cloudy swelling, hyperemia and hemorrhage to local necrosis and firmness. The microscopic findings of early stage of the mastitis were appearance of large numbers of heterophils in the glandular lumina and ducts accompanied by degeneration, necrosis and desquamation of epithelial cells, and also infiltration of heterophils, hemorrhage and edema in the interstitial tissue, and destruction of alveoli. Later, proliferation of firoblasts, plasma cells, lymphocytes, eosinophils and histiocytes appeared in the glandular tissue and necrotic foci of glandular tissue were surrounded by highly proliferated connective tissue. Granuloma-like inflammatory changes could be observed in the glandular tissue on the 7th days after infusion. The inflammatory response in the group infused with E. coli strain isolated from the natural case of acute mastitis was rapid and severe as compared with that of chronic mastitis. In the endotoxin-infused group the morphological changes were similiar to those of the bacterial suspension-infused groups.

Background: Panax stipuleanatus represents a folk medicine for treatment of inflammation. However, lack of experimental data does not confirm its function. This article aims to investigate the analgesic and anti-inflammatory activities of triterpenoid saponins isolated from P. stipuleanatus. Methods: The chemical characterization of P. stipuleanatus allowed the identification and quantitation of two major compounds. Analgesic effects of triterpenoid saponins were evaluated in two models of thermal- and chemical-stimulated acute pain. Anti-inflammatory effects of triterpenoid saponins were also evaluated using four models of acetic acid-induced vascular permeability, xylene-induced ear edema, carrageenan-induced paw edema, and cotton pellet-induced granuloma in mice. Results: Two triterpenoid saponins of stipuleanosides R₁ (SP-R₁) and R₂ (SP-R₂) were isolated and identified from P. stipuleanatus. The results showed that SP-R₁ and SP-R₂ significantly increased the latency time to thermal pain in the hot plate test and reduced the writhing response in the acetic acid-induced writhing test. SP-R₁ and SP-R₂ caused a significant decrease in vascular permeability, ear edema, paw edema, and granuloma formation in inflammatory models. Further studies showed that the levels of inflammatory mediators, nitric oxide, malondialdehyde, tumor necrosis factor-α, and interleukin 6 in paw tissues were downregulated by SP-R₁ and SP-R₂. In addition, the rational harvest of three- to five-year-old P. stipuleanatus was preferable to obtain a higher level of triterpenoid saponins. SP-R₂ showed the highest content in P. stipuleanatus, which had potential as a chemical marker for quality control of P. stipuleanatus. Conclusion: This study provides important basic information about utilization of P. stipuleanatus resources for production of active triterpenoid saponins.

The aim of the present study is to investigate the anti-inflammatory and antimicrobial activity of petroleum ether and ethanol extracts of Scutia myrtina (Family: Rhamnaceae). In anti-inflammatory activity carrageenan and histamine induced paw oedema and cotton pellet induced granuloma for acute and chronic inflammatory models were studied in Wister albino rats. Based on the results of the present study it can be concluded that petroleum ether and ethanol extract of Scutia myrtina at 400 mg/kg has potential anti-inflammatory effect and they act in a dose dependent manner. Both extracts of Scutia myrtina showed antimicrobial activity against all bacterial and fungal strains tested at the concentration of $100\;{\mu}g$/ml. From the result, it can be concluded that the Scutia myrtina contain antibacterial and antifungal principle. Further more, besides the confirmation of the popular use; the obtained results demonstrate this herbal drug to represent a new source of antimicrobial and anti-inflammatory agent.

Background: Laryngeal contact granuloma is an inflammatory hypertrophic granulation tissue arising at around the vocal process of arytenoid cartilage. Various approaches are currently used for the treatment, but a solid guideline has not been established. Objectives: We aimed to compare the each treatment modality in the hope of suggesting a guideline for the successful management of laryngeal contact granuloma. Method: Eighty-seven treatment cases of 56 patients were analyzed. Cases having recent intubation history were excluded from the study. All patients received vocal hygiene education. Proton pump inhibitors (PPI, N = 33) or H2 receptor antagonists ($H_{2}RA$, N =26) were used as a first-line treatment. Among the non-responders to $H_{2}RA$, 11 cases received PPI as a second-line therapy. Eight cases received botulinum toxin injection and 9 cases had laryngomicrosurgical removal. Results: As an initial therapy, response rate to PPI and $H_{2}RA$ was 60.6% and 38.5% respectively, which was not statistically different (p=0.091). Response rate of PPI as the second-line therapy was 36.3% (p=0.162 when compared to that of first-line PPI therapy). Response rate of Botulinum toxin injection was 75%. All cases of surgical removal recurred in a relatively short period (mean 1.9months). Conclusion: In patients having laryngeal contact granuloma, combined therapy with vocal hygiene education and PPI medication would provide more than 60% of therapeutic response. Botulinum toxin injection is highly effective even in non-responders to antireflux therapy. The only indications of surgery are to resolve diagnostic doubt or to treat acute airway compromise.

It is known that injuries to the dentin have a corresponding inflammatory effect on the pulp and these inflammatory effects frequently result in pulpal pathoses due to progressive degradation of pulpal connective tissue. It was supposed that the tissue degradation in different inflammatory process was controlled by proteinase activity and antiproteinase activity. Therefore, the purpose of this study was to examine the pulp and periapical pathoses in terms of the activities of proteinase and proteinase inhibitor, 37 pulpal tissues were divided by clinical diagnostic criteria into normal pulp, acute inflamed pulp, and chronic inflamed pulp, and then those groups were subdivided by histopathological findings into 5 pulpal pathoses groups, i.e. normal pulp (P1, n=8), chronic pulpitis with fibrotic change (P2, n=2), chronic pulpitis with dystrophic calcification (P3, n=11), chronic pulpitis with pulp abscess (P4, n=7), acute pulpitis with necrotic change (P5, n=4), 26 periapical tissues were also divided by ordinary histopathological findings into 3 periapical pathoses group, i.e., granuloma (A1, n=17), cyst (A2, n=2) and abscess (A3, n=7). The activities of proteinases (cathepsin G, MMP-3) and proteinase inhibitors (${\alpha}1$-AT, TIMP-1 and, SLPI) were evaluated by RT-PCR and immunohistochemical methods. The results were as follows. 1. Generally, the intensity of immunohistochemical staining of proteinases and proteinase inhibitors increased in P2 and P5 groups compared to P1 group. 2. The immunohistochemical stain of proteinases and proteinase inhibitors was intensely detected in P2 group, showing low inflammatory reaction and low tissue degradation, but it was reduced in P3 and P4 groups, showing severe tissue degradation. 3. The distribution of proteinases and proteinase inhibitors in pulpal pathoses was consistently presented by immunohistochemical staining, while the expression of proteinase and/or proteinase inhibitors mRNAs in pulpal pathoses was occasionally detected by RT-PCR methods. 4. RT-PCR of proteinase and proteinase inhibitors was usually positive in P2, showing rare tissue degradation, but it was almost negative in P3 and P4, showing severe tissue degradation. 5. We presume that the reason why the level of proteinase and proteinase inhibitors was so sparse in RT-PCR method is due to the abrupt decrease of mRNA synthesis or degradation of synthesized mRNA of proteinase and/or proteinase inhibitors depend on the inflammatory reaction and/or on the degradation of pulp tissues(P3, P4). 6. Pulpal pathoses groups showed significant lower RT-PCR detection of proteinases and proteinase inhibitors than the periapical pathoses group(p<0.05), and there is no significant difference among the periapical pathoses groups(p>0.05).

Free tissue transplantation is commonly performed with the brilliant achievement in microsurgery and anticoagulants and antithrombotic agents have been prescribed in the procedures. However, there is no clean-cut indication as to which agents would be more effective in every steps and final consequences. Low molecular weight heparins inhibiting coagulation in plateletrich plasma and acting on the vascular endothelium have antithrombotic and fibrinolysis action. The experiment with rat groin free flap transplantation after 6-hour ischemia and injection of the low molecular weight heparin was performed and the results between the injection and non-injection group were analysed as follows, 1. Both of the 24-hour groups, vessel patency was not proportional to color change of the groin flap. 2. On the second day after anastomois, heparin-injection group showed intact intima, patent lumen without thrombus, and mild granulomatous inflammation around the suture material and control group with doubtful patency revealed intimal loss and thrombus formation. 3. On the 5th, 7th, and 9th postoperative day, heparin group was patent in anastomosis and showed acute inflammatory cells. 4. The 7th-week period, heparin-injection group showed intact flap color, patent lumen with intact intima and persistent foreign body granuloma.
