The present invention provides compositions comprising at least one cation selected from the group consisting of Ga+3 and La+3, that effectively inhibit the discharge of nematocysts or polar capsules. The compositions described herein are effective at inhibiting nematocyst or polar capsule discharge when applied topically prior to exposure to nematocysts. The present invention further provides methods for inhibiting the discharge of nematocysts or polar capsules, comprising applying to the skin of a subject prior to contact with the nematocyst or polar capsule a compositions comprising at least one cation selected from the group consisting of Ga+3 and La+3. Thus, the present invention provides protection for swimmers, divers and fishermen, from nematocysts or polar capsules discharged from stinging marine organisms such as Cnidaria and Myxozoa.
本发明提供含有至少一种选自Ga+3和La+3阳离子的组合物,可有效抑制刺细胞或极囊的释放。在接触刺细胞前局部使用所述组合物可有效抑制刺细胞或极囊的释放。本发明还提供抑制刺细胞或极囊释放的方法,包括在接触刺细胞或极囊前将含有至少一种选自Ga+3和La+3阳离子的组合物施用于受试者的皮肤。因此,本发明为游泳者、潜
水员和渔民提供了保护,防止被刺胞动物(如刺胞动物和黏孢子虫)释放的刺细胞或极囊蜇伤。
