Purpose: selection of anticoagulants based on EDTA-Na 2 and methods their use for working with the hemolymph Australian red claw crayfish (C. quadricarinatus) Materials methods. For study, different-sized males females australian red-clawed (Cherax quadricarinatus (Von Martens, 1868)) were used. was used as an anticoagulant, concentrationof which 4%. A ml syringe a 23G needle removal pre-washed...

OBJECTIVE To determine the effect of temperature on lethality of venom from Chironex fleckeri (the potentially fatal box jellyfish). DESIGN Venom extracted from nematocysts of mature Chironex fleckeri specimens was exposed to temperatures between 4 degrees C and 58 degrees C for periods of two, five or 20 minutes, and then injected into freshwater crayfish (Cherax quadricarinatus) to assess l...

We describe a histamine-activated Cl(-) conductance in the X-organ neurons from crayfish Cherax quadricarinatus, which has comparable properties to the homomultimeric histamine-gated ion channels described in Drosophila. Topical application of histamine inhibited spontaneous neuronal firing in the X-organ sinus gland tract, concomitant with an increase in the membrane conductance. In X-organ ne...

The lipopolysaccharide binding domain (LBD) in anti-lipopolysaccharide factor (ALF) is the main functional element of ALF, which exhibits antimicrobial activities. Our previous studies show that the peptide LBDv, synthesized based on the modified sequence of LBD (named LBD2) from FcALF2, exhibited an apparently enhanced antimicrobial activity. To learn the prospect of LBDv application, the char...
