Agkistrodon halys is one of several dangerous snake species in Iran. Among the most important signs and symptoms in patients envenomated by this snake is disseminated intravascular coagulation. A thrombin-like enzyme, called AH143, was isolated from Agkistrodon halys venom by gel filtration on a Sephadex G-50 column, ion-exchange chromatography on a DEAE-Sepharose and high performance liquid ch...

C-type lectin-like proteins (CTLPs) isolated from snake venoms are the largest and most complex non-mammalian vertebrate C-type lectin-like domain family. In the present study, we simultaneously amplified four cDNAs encoding different types of CTLP subunits from the venoms of two different species of snakes by RT-PCR with a single sense primer and a nested universal primer - two CTLP subunit-en...

The authors report a case of Trimeresurus albolabris (white-lipped green pit viper) bite in a 6-year-old girl living in rural Yuen Long. Despite repeated use of Agkistrodon halys antivenin, the patient developed severe coagulopathy with defibrination syndrome on the fourth day of envenomation, which was also refractory to therapy with fresh frozen plasma. When treatment was switched to green pi...

The complete amino acid sequence of acidic Agkistrodon halys blomhoffii phospholipase A2 has been redetermined by a combination of manual and automatic Edman degradations. Acidic A. halys blomhoffi phospholipase is a single polypeptide chain consisting of 122 amino acids and is highly homologous in sequence with corresponding regions of phospholipase A2 from a variety of sources. Prism crystals...

The venoms from central Asian snakes (Echis carinatus, Echis multisquamatus, Vipera ursini, Vipera lebetina, Agkistrodon halys halys and Naja naja oxiana) contain several enzymes with amidolytic- and procoagulant activity. We have characterized the activities and the mol. wts of the venom enzymes that are able to convert a number of commercially available chromogenic substrates for activated co...

Background & Aims: In recent years, the feasibility of hydrophilic nanoparticles has been broadly investigated for use in drug delivery and therapeutic systems. Due to the problems of traditional adjuvants, in this study Agkistrodon halys (Ah) Snake venom was loaded in chitosan nanoparticles (CS NPs) in order to be used as an advanced adjuvant and antigen delivery system in ant...

the snake venom´s thrombin-like enzymes comprise a number of serine proteases, which are functionally and structurally related to thrombin. purification and partial characterization of a thrombin-like enzyme from the venom of the iranian snake, agkistrodon halys, was the aim of this study. purification was carried out by a combination of variety of chromatographic methods that included: gel fil...
