ABSTRACT
<p><b>OBJECTIVE</b>To study the effects of Aloe coarse polysaccharide on the levels of growth factors (EGF, TGF-alpha, TGF-beta1) and interleukins (IL-1beta, IL-6, IL-8) and tumor necrosis factor (TNF) in cultured keratinocytes.</p><p><b>METHOD</b>The cultured keratinocytes were treated with Aloe coarse polysaccharide at concentrations of 75, 150, 300, 600, 1 200 mg x L(-1) land the equal volume of media as control group. The levels of EGF, TGF-alpha, TGF-beta1, IL-1beta, IL-6, IL-8 and TNF in the supernatants of cultured keratinocytes were assayed by enzyme-linked immunosorbent assay (ELISA) and radioimmunoassay (RIA).</p><p><b>RESULT</b>Compared with the control group, the levels of EGF, TGF-alpha, IL-1beta, IL-6 and IL-8 were significantly increased by treatment with Aloe coarse polysaccharide (P < 0.05, P < 0.01) and in a dose dependent manner, and the levels of TGF-beta1 and TNF were also increased but no statistical significance.</p><p><b>CONCLUSION</b>Aloe coarse polysaccharide may promote keratinocytes to secrete EGF, TGF-alpha, IL-1beta, IL-6 and IL-8.</p>
