Novel Sodium Channel Inhibitor From Leeches
Considering blood-sucking habits of leeches from surviving strategy of view, it can be hypothesized that leech saliva has analgesia or anesthesia functions for leeches to stay undetected by the host. However, no specific substance with analgesic function has been reported from leech saliva although clinical applications strongly indicated that leech therapy produces a strong and long lasting pa...
متن کاملCharacterization of cDNA sequence encoding for a novel sodium channel -toxin from the Iranian scorpion Mesobuthus eupeus venom glands
The venoms of Buthidae scorpions are known to contain basic, single-chain protein -toxins consisting of 60-70 amino acid residues that are tightly cross-linked by four disulfide bridges. Total RNA was extracted from the venom glands of scorpion Mesobuthus eupeus collected from the Khuzestan province of Iran and then cDNA was synthesized with the modified oligo (dT) primer and extracted total R...
متن کاملSodium Channel and Sodium
Levels of sodium pump and of sodium channels were measured at different stages of membrane purification. Microsomal fractions of normal human muscle have maximal binding capacities for tetrodotoxin of 230 fmol/mg of protein and of 7.4 pmol/mg of protein for ouabain. Dissociation constant for the complexes formed by the tetrodotoxin derivative and by ouabain with their respective receptors were ...
متن کاملSodium transport inhibitor from bovine hypothalamus.
A low molecular weight, basic, nonpeptidic factor that possesses sodium transport inhibitory properties has been prepared from bovine hypothalamus by acid/acetone extraction and gel filtration. Concentration and partial purification was achieved by ion-exchange chromatography. This substance inhibits active Na+ transport across anuran membranes, inhibits ouabain binding to frog urinary bladder,...
متن کاملLeeches
Real worms don't eat bacteria. Leeches are segmented, eucoelomate worms of the phylum Annelida, distinguished from other annelids by anterior and posterior suckers used for locomotion and feeding — on blood or soft body parts of other animals. They are not to be confused with nematodes, which lack these (and most other) features. Leeches are mainly aquatic, but the Asian land leeches are well k...
