| comparative enzymatic study of hplc-fractionated crotalus venoms. | 1. ten venoms of the genus crotalus (crotalus adamanteus, crotalus atrox, crotalus durissus durissus, crotalus horridus horridus, crotalus lepidus, crotalus polystictus, crotalus molossus molossus, crotalus pusillus, crotalus scutulatus scutulatus, venom b, and crotalus viridis lutosus) were fractionated using hplc anion and cation exchange chromatography. 2. hplc venom fractions were tested for hemorrhagic, hemolytic, and proteolytic activities. 3. crude virginia opossum (didelphis virginiana) ... | 1989 | 2680253 |
| envenomation by the mexican lance-headed rattlesnake crotalus polystictus: a case report. | a case of envenomation by the mexican lance-headed rattlesnake, crotalus polystictus, resulted in local swelling and muscle fasciculation, which abated after i.v. antivenin and an area of necrosis healed. a mild thrombocytopenia and hypofibrinogenemia with elevation of fibrin split products was noted. | 1982 | 7164112 |
| snake venom hemotoxic enzymes: biochemical comparison between crotalus species from central mexico. | snakebite envenoming is a serious medical problem in different areas of the world. in latin america, the major prevalence is due to snakes of the family viperidae, where rattlesnakes (crotalus) are included. they produce hemotoxic venom which causes bleeding, tissue degradation and necrosis. each venom has several enzymatic activities, producing different effects in the envenoming, doing its clinical effects difficult to study. comparison between venom molecules is also difficult when different ... | 2019 | 31014025 |
| venom ontogeny in the mexican lance-headed rattlesnake (crotalus polystictus). | as trophic adaptations, rattlesnake venoms can vary in composition depending on several intrinsic and extrinsic factors. ontogenetic changes in venom composition have been documented for numerous species, but little is known of the potential age-related changes in many rattlesnake species found in méxico. in the current study, venom samples collected from adult and neonate crotalus polystictus from estado de méxico were subjected to enzymatic and electrophoretic analyses, toxicity ... | 2018 | 29970805 |
