The effects of aqueous and alkaline extracts from Agaricus blazei Murill, an edible mushroom used as folk medicine in Brazil, Japan, and China to treat several illnesses, were investigated on the basis of the inflammatory process induced by different agents. Oral administration of A. blazei extracts marginally inhibited the edema induced by nystatin. In contrast, when complete Freund's adjuvant was used as the inflammatory stimulus, both extracts were able to inhibit this process significantly (P < .05, analysis of variance followed by Tukey-Kramer multiple comparison post hoc test), although it inhibited the granulomatous tissue induction moderately. These extracts were able to decrease the ulcer wounds induced by stress. Also, administration of extracts inhibited neutrophil migration to the exudates present in the peritoneal cavity after carrageenin injection. Therefore, it is possible that A. blazei extracts can be useful in inflammatory diseases because of activation of the immune system and its cells induced by the presence of polysaccharides such as beta-glucans.

D004487 Edema Abnormal fluid accumulation in TISSUES or body cavities. Most cases of edema are present under the SKIN in SUBCUTANEOUS TISSUE. Dropsy,Hydrops,Anasarca
D005620 Freund's Adjuvant An antigen solution emulsified in mineral oil. The complete form is made up of killed, dried mycobacteria, usually M. tuberculosis, suspended in the oil phase. It is effective in stimulating cell-mediated immunity (IMMUNITY, CELLULAR) and potentiates the production of certain IMMUNOGLOBULINS in some animals. The incomplete form does not contain mycobacteria. Freund Adjuvant,Adjuvant, Freund,Adjuvant, Freund's,Freunds Adjuvant
D006099 Granuloma A relatively small nodular inflammatory lesion containing grouped mononuclear phagocytes, caused by infectious and noninfectious agents. Granulomas
D000276 Adjuvants, Immunologic Substances that augment, stimulate, activate, potentiate, or modulate the immune response at either the cellular or humoral level. The classical agents (Freund's adjuvant, BCG, Corynebacterium parvum, et al.) contain bacterial antigens. Some are endogenous (e.g., histamine, interferon, transfer factor, tuftsin, interleukin-1). Their mode of action is either non-specific, resulting in increased immune responsiveness to a wide variety of antigens, or antigen-specific, i.e., affecting a restricted type of immune response to a narrow group of antigens. The therapeutic efficacy of many biological response modifiers is related to their antigen-specific immunoadjuvanticity.
