Vinpocetine dose-dependently ameliorates PF induced by bleomycin administration since vinpocetine effectively restored the normal body weight gain rates, pulmonary architecture, and collagen fiber distribution and suppressed the elevated BALF cell count, lymphocytes and neutrophils percentage, BALF, IL-6, TNF-α, and TGF-β1 levels and LDH activity, lung tissue MDA level, PDE activity, hydroxyproline content, immunohistochemical expression of α-SMA and CD68 positive macrophage, and fibrosis score. Here, CD68 is linked to pemphigus foliaceus.
