Snake venom is complex and diverse in composition and varied in the toxicity, pharmacology, and clinical symptoms, which can be divided into neurotoxin, hemostasis toxin, necrotoxin, cardiotoxin, nephrotoxin, myotoxin, and other types. Snake venom researches include toxicology, genomics, transcriptomics, proteomics, antiveomics, and glycomics. According to the pharmacological properties, the separation and purification of specific venom proteins, combined with the approaches of molecular biology and structural chemistry, can be used in the pharmaceutical, examination, and antivenom manufacture. Snake venom compositions have been used in treating diabetes, hypertension, chronic pain, and stroke, as well as displaying anticoagulant and anti-inflammatory effects. This course mainly aims to present the diversity of snake venoms as well as the method, achievement, development, and application of snake venom technology. Students in the course will also read literatures and make oral presentations.
