[Pharmacologic effects of an extract of Arillus longan (Lour.) Steud. and Gecko]

ALG is an extract from Arillus longan and Gecko. Our experiment has shown that ALG ig 20 ml/kg/d X 10 elevates significantly tolerance in mice under low and high temperatures and anoxia, and also increases the body-weight of normal mice, while ALG ig 15 ml/kg/d X 14 protects body-weight from decreasing in reserpinized mice. An increase in spleen-weight has also been observed in normal mice with ALG ig 20 ml/kg/d X 7, and ALG ig 15 ml/kg/d X 10 elevates the clearance rate of iv charcoal particles in normal mice.
