Using gel-filtration chromatography and reverse-phase (RP) HPLC we have purified a presynaptic neurotoxin (designated as trimucrotoxin) from the crude venom of Taiwan habu (Trimeresurus mucrosquamatus). Its complete primary structure was solved by an automated N-terminal sequencing and cDNA sequencing method. The enzyme inhibited the twitch of the chick biventer cervicis muscle at 0.1-1 microgr...
We examined the effect of Waglerin-1, a peptide of 22 amino acid residues purified from the venom of Wagler's pit viper (Trimeresurus wagleri), on the whole cell current response (I(GABA)) of freshly isolated murine hypothalamic neurons to gamma-aminobutyric acid (GABA). Although the application of 32 microM Waglerin-1 alone had no effect on membrane conductance, coapplication with GABA increas...
Two lethal toxins were isolated from Trimeresurus wagleri venom by fast protein liquid chromatography (molecular sieve) and high performance liquid chromatography (reverse phase). The toxins (termed peptide I and II) had mol. wt of 2504 and 2530, respectively, pIs of 9.6-9.9 and lacked phospholipase A, proteolytic, and hemolytic activity. Lethal peptide I had a murine i.p. LD50 of 0.369 mg/kg, ...
Snake bites are life-threatening injuries that can require intensive care. The diagnosis and treatment of venomous snake bites is sometimes difficult for clinicians because sufficient information has not been provided in clinical practice. Here we review the literature to present the proper management of bites by mamushi, habu, and yamakagashi snakes, which widely inhabit Japan and other Asian ...
Snake envenomation has been estimated to affect 1.8 million people annually with about 94,000 deaths mostly in poor tropical countries. Specific antivenoms are the only rational and effective therapy for these cases. Efforts are being made to produce effective, affordable and sufficient antivenoms for these victims. The immunization process, which has rarely been described in detail, is one ste...
Bean thrips, Caliothrips fasciatus, is native to western North America. Once considered a pest of several crops in its native area, its pest status has waned over recent decades. However, due to its habit of aggregating in the navel of navel oranges, bean thrips remains economically important because some countries importing oranges from California have designated it a quarantine pest. Despite ...
A taxonomic review of 23 species of the subgenus Pseudoophonus Motschulsky, 1844, the genus Harpalus Latreille, 1802, occurring in China is given, and a key to these species is provided. The species are divided in three species groups and five subgroups, the distinctive characters of which are listed. The following new synonyms are established: Harpalus calceatus Duftschmid, 1812 = Anisodactylu...
