Through experiments

we find

in all kinds of toxins of spiders

many erzymes and some neurotoxins that have selective effect on the nervous system of mammals and insects. Selenocosmia huwena is a new spider of theraphosidae found in Yunan and Guangxi

whose toxin contains SLH-1

four neurotoxins (namely HWTX-I

HWTX-Ⅱ

HWTX-V and HWTX-XI) and some complicated mixtures consisted of polypeptides (mainly those of mulecular 2×103-9×103)

proteins and low-molecular-weight substances. With many activated and physiological effects

the toxin of selenocosmia huwena will be used intensively in curing epilepsy

cancers

cerebral hemorrhage

diabetes and hepatitis.
