The proliferative effect of aloe coarse polysaccharide on the cultured epidermal cells in vitro / 中国药理学通报

Aim To investigate the effects of aloe coarse polysaccharid on proliferation and the intracellular calcium level and the leakage rate of lactate dehydrogen-ase(LDH) of the epidermal cellsin vitro.Methods The epidermal cells were treated with aloe coarse po-lysaccharid of75,150,300,600 and 1 200 mg.L-1respectively.The proliferation of epidermal cells wasobserved interms of the proliferation curve and the pop-ulation doubling/day(PD/d).The concentration ofintracellular calcium and the leakage rate of LDHwerealso measured.Results In aloe coarse polysaccharidgroup,a dose-dependent and statistically significant(P
