There are several methods used for screening and evaluating anti -inflammatory agents. Among these, 'Granuloma pouch' technic introduced by Hans Selye is considered as a simple and reliable method. The procedure of 'Granuloma pouch' technic is as follows: Rats were used as experimental animals. An air pocket was produced in the subcutaneous tissue of the mid-dorsal portion between the shoulders by the injection of 25ml of the air which was immediately followed by injection of 1 ml of 1% croton oil as irritant. Inflammatory exudate accumulated in the pouch during the succeeding 14 days. After sacrificing the rats on the last day of the experiment, the amount of the exudate in the pouch and the weight of the granuloma tissue was measured. The author observed and compared the anti-inflammatory activities of the several steroid compounds when they are given by different methods. 1. In the control rats, the amount of inflammatory fluid and the weight of the granuloma tissue after 14 days were 9ml and 3gm respectively. 2. Injection of hydrocortisone 1.5mg subcutanenusly, 24 hours prior to pouch formation into the area where the pouch is to be formed, successfully prevented the inflammatory processes. 3. Injection of hydrocortisone 1.5mg in the air pocket formed 24 hours prior to croton oil injection was ineffective. 4. Injection of hydrocortisone into the pouch at a distance of 5mm apart from the pouch formation did not prevent the development of inflammation. 5. Anti-inflammatory activities of hydrocortisone administered systematically(injected intramuscularly into the area which is not related to the area of pouch formation) for 10 days were proportional to the doses of hydrocortisone administered. 6. DOCA, testosterone, and progesterone did not show the anti-inflammatory activity.

For evaluating the cytolytic effects on the mouse thymocytes, four typical antiinflammatory steroids (dexamethasone, triamcinolone acetonide, prednisolone, hydrocortisone) were selected in this study. When steroids were treated to the mouse thymocytes in vitro cytolysis occurred with dose-dependent fashion and the activities were found to be paralle with the known local anti-inflammatory activities. In vivo thymus atrophogenic activities appeared by the treatment of topical and subcutaneous applications of the derivatives were also found to dose-dependent, but not coincided with the thymocyte cytolytic activities in vitro and local anti-inflammaatory activity in the case of triamcinolone acetonide. Triamicinolone acetonide induced potent thymocyte cytolysis in vitro, but showed less thymus atrophy.

Objectives : The purpose of this study is to investigate the effect and side effects of steroids on dermatitis and skin barrier through lipid metabolism. And to propose using Herbal medicine to suppress Steroid rebound and prevent side effects. Methods : We reviewed recent studies about the relationship between dermatitis, skin lipid, steroid, and herbal medicine through Google scholar. Results : In various inflammatory skin diseases, the corticosteroid is selected as the primary drug due to its strong anti-inflammatory and immunosuppressive effect. However, long-term use of steroids has a variety of side effects, especially lipid metabolism disruption, which aggravates skin barrier damage underlying various skin diseases and is more susceptible to inflammatory reactions. Conclusions : Herbal medicine is used as a comprehensive approach, and it can be used to reduce the frequency of steroid exposure by protecting against barrier damage by controlling anti-inflammatory, antioxidant, and systemic/sebaceous lipid metabolism and stratum corneum protein differentiation.

Background: As nonsteroidal anti-inflammatory drugs (NSAIDs) and steroids have similar effects, steroids can be avoided to reduce adverse effects. This study aimed to compare the differences in symptom improvement after subacromial injection of steroids or NSAIDs. Methods: Sixty patients with rotator cuff syndrome for at least 3 months were enrolled and divided into steroid and NSAID groups. The steroid group received a mixture of 1 mL of triamcinolone acetonide (40 mg/mL) and 1 mL of lidocaine hydrochloride 2%, while the NSAID group received a mixture of 1 mL of Ketorolac Tromethamine (30 mg/mL) and 1 mL of lidocaine hydrochloride 2%. The patients were assessed before and at 3, 6, and 12 weeks after the procedure. Shoulder scores from visual analog scale (VAS), American Shoulder and Elbow Surgeons (ASES), and University of California Los Angeles (UCLA) were used for evaluation. Results: Both groups showed improvements in the clinical outcomes. Overall VAS, ASES, and UCLA scores improved from 6.9, 32.7, and 16.0 before the procedure to 2.0, 1.2, and 1.1; 81.5, 87.6, and 88.5; and 29.7, 31.8, and 32.0 at weeks 3, 6, and 12 weeks after the procedure, respectively. Twenty-six patients (86.7%) in the steroid group and 28 (93.3%) in the NSAID group reported satisfactory treatment outcomes. There were no significant differences in the outcomes between the two groups (p=0.671). Conclusions: Subacromial injection of NSAIDs for rotator cuff tendinitis with shoulder pain had equivalent outcomes with those of steroid injection at the 12-week follow-up.

ln order to develope anti-inflammatory glucocorticoids for local use without systemic side-effects, ester and amide derivatives of 20$\xi$-dihydroprednisolonic acid have been prepared. When binding affinities of these compounds to glucocorticoid receptor of rat liver cytosol were compared, all a-isomer at C-20 showed higher binding affinities than the corres¬ponding $\beta$-isomer. The size of the substituents at C-21 had significant influences on binding affinities, which were related with their lipophilicity.

Genus Penicillium comprising the most important and extensively studied fungi has been well-known as a rich source of secondary metabolites. Our study aimed to analyze and investigate biological activities, including in vitro anti-cancer, anti-inflammatory and anti-diabetic properties, of metabolites from a marine-derived fungus belonging to P. levitum. The chemical compounds in the culture broth of P. levitum strain N33.2 were extracted with ethyl acetate. Followingly, chemical analysis of the extract leaded to the isolation of three ergostane-type steroid components, namely cerevisterol (1), ergosterol peroxide (2), and (3β,5α,22E)-ergosta-6,8(14),22-triene-3,5-diol (3). Among these, (3) was the most potent cytotoxic against human cancer cell lines Hep-G2, A549 and MCF-7 with IC₅₀ values of 2.89, 18.51, and 16.47 ㎍/mL, respectively, while the compound (1) showed no significant effect against tested cancer cells. Anti-inflammatory properties of purified compounds were evaluated based on NO-production in LPS-induced murine RAW264.7 macrophages. As a result, tested compounds performed diverse inhibitory effects on NO production by the macrophages, with the most significant inhibition rate of 81.37±1.35% at 25 ㎍/mL by the compound (2). Interestingly, compounds (2) and (3) exhibited inhibitory activities against pancreatic lipase and α-glucosidase enzymes in vitro assays. Our study brought out new data concerning the chemical properties and biological activities of isolated steroids from a P. levitum fungus.

This research was performed to examine an anti-inflammatory effects of Gamisangryosamul-Tang(GSS) and anti-pruritus effects of Ziyang-Go(Salve). This study was processed by three experiments; Experiment 1: Inhibitory activity of GSS extract on the degranulation of mast cell and histamine release in plasma induced by compound 48/80 i.p, injection after the pretreatment of GSS extract i.p, injection in Sprague-Dawley rats, Experiment 2: Anti-inflammatory effect of GSS extract on macropharge raw 264,7 cells treated by LPS 250 ppm (before 2 hours). Experiment 3: Measurement of passive cutaneous anaphylaxis and atopic dermatitis using NC/Nga mice, GSS extract inhibited histamine release by 70% compared to compound 48/80 treated control group and histologically significantly reduced (P<0,01) the degranulation of mast cell in SD rats. In GSS extract treated group, the expression of TNF-α in macropharge cell showed the remarkable inhibitory effect about 62% (P<0,01) compared to LPS treated control group. The expression of IL-6 appeared more effective by 46% than the LPS treated control group and by 6% compared to hydrocortison treated group, Comparing with steroid (0.05% prednisolon) ointment, Ziyan-Go treated group showed the significant(30%) recovery on skin response index in atopic dermatis like anaphylaxis mice(NC/Nga), Finally, in scratching behavioral tests of NC/Nga mice for three weeks, Ziyang-Go treated group significantly (P<0.05) suppressed the pruritus on the face, neck, ears and dorsal skin than inbred NC/Nga mice. However, the change of IgE and IFN-γ from the spleen cell of NC/Nga mice was not significantly different between the oral intake of GSS extract group and of saline intaked control group. Summary and Conclusion: This study demons trates that Ziyang-go have the equal anti-pruritus effect to steroid ointment and GSS extract have the notable immunologic activity on inflammatory in vivo and in vitro model. Advanced experiment of this study will be required for more reliable information about the correlation between the lymphokine (i.e. IgE) and the anti-allergic effects of GSS.

Anti-inflammatory glucocorticoid (GC) derivatives have been clinically used in immune-malfunctional diseases for their immunosuppressive activity. However, there is still a lack of knowledge on the relationship between anti-inflammatory and immunosuppressive activities. In order to compare immunosuppressive activities with the known anti-inflammatory activities of the GC derivatives, eight clinically used GC derivatives including hydrocortisone, prednislone, 6$\alpha$-methyl prednisolone, triamcinolone, dexamethasone, betamethasone, triamcinolone acetonide and fluocinolone acetonide were selected, and lymphoblastosis inhibition and plaque-forming cell (PFC) response in mice were studied as immunological parameters. In Con A-induced lymphoblatosis inhibition invitro, all derivatives showed potent inhibition $IC_{50}$ values of the derivaties except methyl prednisolone and triamcinolone were less than $10^{-7}$M and good dose dependency was obtained. This result was well correlated with that of their anti-inflammatory potencies obtained. This result was well correlated with that of their anti-inflammatory potencies and their receptor binding affinities. However, in PFC response, consistent result were not obtained. Total numbers of PFCs per spleen were decreased by some derivatives, but numbers of PFCs per $10^6$ cells were not decreased by systemic administration of but numbers of PFCs per $10^6$ cells were not decreased by systemic administration of GC at the dose of 0.05 mg/mouse. Furthermore, at the dose of 0.1 mg/mouse, numbers of PFCs per $10^6$ cells were found to be increased, although total PFCs per spleen were decreased.
