Unlabelled:
On the basis of its fibroblast growth factor (FGF) inhibitory effect we assessed the possible inhibitory anti-inflammatory role of Pygeum Africanum extract (Tadenan) on FGF and transforming growth factor beta (TGF beta 1/LAP) expression of macrophages and neutrophils in broncho-alveolar lavage fluid (BAL) of rats in a bleomycin-induced acute inflammation model. The rats were divided into three groups: 17 untreated controls, 10 bleomycin-instilled rats, receiving NaCl (0.9%), and 10 rats receiving Pygeum Africanum extract. On the 12th (and 15th day) we performed BAL and after labelling of cells expression of FGF and TGF beta 1 (LAP) was measured by flow-cytometry. We made a quantitative analysis of BAL cells as well. One-way ANOVA was used for statistical analysis. We found in Pygeum Africanum extract treated group 1, a significantly decreased number of neutrophil granulocytes (p < 0.05) compared with other groups 2, there was a considerable decrease (not significant) in expression of TGF beta 1(LAP) on BAL macrophages, but not in case of FGF.
In Conclusion:
our results show the possible 1. inhibitory effect of this drug on TGF beta 1 (LAP) expression, 2. anti-inflammatory role on neutrophil granulocytes.
