The granulomatous response to schistosome eggs is a CD4 T-cell-dependent, Th2-cytokine-dominated immunopathologic response. As infection proceeds to chronicity, both granuloma formation and egg-induced cytokine production become downregulated, and previous experiments have implicated CD8 T cells in this process. One mechanism by which CD8 T cells could suppress immunopathology is through the pr...

Mirabilis Jalapa Linn. is a widely used traditional medicine in many parts of the world for the treatment of various diseases viz. virus inhibitory activity, anti tumour activity. It is claimed in traditional medicine that the leaves of the plant are used in the treatment of inflammation. In the present study, the total alcoholic extract and successive petroleum ether fractions of leaves of Mir...

In schistosomiasis, egg-induced hepatic granuloma formation is a cytokine-mediated, predominantly CD4(+) Th2 immune response that can give rise to hepatic fibrosis. Hepatic fibrosis is the main cause of increased morbidity and mortality in humans with schistosome infection. Taurine has various physiological functions and hepatoprotective properties as well as anti-inflammatory and immunomodulat...

Natural bactericidal resistance to Mycobacterium bovis BCG is under the control of a single gene, designated Bcg. Lung granuloma formation in susceptible (Bcgs) and resistant (Bcgr) mice was studied in two sets of Bcg-congenic systems, namely, the BALB/c (Bcgs)-C.D2 (BALB/c.Bcgr) pair and the B10.A (Bcgs)-B10.Ar (Bcgr) pair, by using BCG as well as foreign body granuloma-inducing agents (dextra...

BACKGROUND Traditional Chinese medicine Taraxacum officinale has been widely used to treat various inflammatory diseases. Taraxasterol is one of the main active components isolated from Taraxacum officinale. Recently, we have demonstrated that taraxasterol has the in vitro anti-inflammatory effects. This study aims to determine the in vivo anti-inflammatory effects of taraxasterol against anima...

This study was to evaluate anti-inflammatory and analgesic effects of the aqueous extract of leaves of Chromolaena odorata (Asteraceae) collected in Brazzaville-Congo. Acute inflammation was induced by using the carrageenan and formaldehyde models, and chronic inflammation by the cotton pellet induced granuloma model. Analgesic effect was evaluated by using the acetic acid-induced writhing, the...

The aim of the present study was to explore the probable anti-inflammatory effect of petroleum ether (PEE), chloroform (CE) and ethanol (EE) extracts obtained from the leaves of Ficus carica Linn. Anti-inflammatory activity was studied by carrageenan-induced rat paw edema and cotton pellet granuloma methods. The extracts were administered orally in doses of 300 and 600 mg/kg/day of body weight ...

Granulomas, organized aggregates of immune cells, are a hallmark of tuberculosis and have traditionally been thought to restrict mycobacterial growth. However, analysis of Mycobacterium marinum in zebrafish has shown that the early granuloma facilitates mycobacterial growth; uninfected macrophages are recruited to the granuloma where they are productively infected by M. marinum. Here, we identi...

The methanol extract of Caesalpinia bonducella leaves were investigated for anti-inflammatory, analgesic and antipyretic activity at the doses of 50, 100 and 200 mg/kg, body weight. The experimental paradigms used were carrageenan, dextran, histamine induced pedal edema and cotton pellet induced granuloma for anti-inflammatory activity, while hot plate and acetic acid induced writhing methods w...

BACKGROUND Hepatic granuloma is reported in 2 - 15% of liver biopsy specimens. It is relatively easy for the pathologist to diagnose, but sometimes arriving at a specific etiology is quite difficult. Until now, there are few published studies about the etiology of hepatic granuloma in Iran. In this study, we attempt to determine the causes of hepatic granuloma from one of the largest referral c...
