Tezpur univ scientists develop novel therapeutic formulation to counter Indian red scorpion sting
IMT News Desk
The novel TDF efficiently neutralised the Indian red scorpion venom and induced an increase in blood glucose level, organ tissue damage, necrosis, and pulmonary edema in Wistar ratsA team of scientists from the Institute of Advanced Study in Science and Technology (IASST), an autonomous institute of the Department of Science and Technology as well as researchers from scholars from Tezpur University NIELIT, Guwahati have invented novel therapeutic drug formulations (TDF) consisting of low doses of commercial ASA, AAA, and vitamin C, for inhibiting the Indian red scorpion venom-induced toxicity and associated symptoms.The drug's efficacy was first tested on Caenorhabditis elegans, a free-living nematodemodel, as an alternative to an in vivo animal model. The research was recently published in the journal Toxins. An Indian patent has also been filed on this novel drug formulation.The study by the team comprising Prof Ashis Mukherjee, Director, Dr M R Khan, Associate Professor and Dr Aparup Patra, IPDF from IASST, Dr Bhabana Das, and Upasana Pujari from Tezpur University, and Dr S Mahanta, from NIELIT, Guwahati demonstrated for the first time that C elegans can be a good model organism for screening the neutralisation potency of the drug molecules against a neurotoxic scorpion venom.The novel TDF efficiently neutralised the Indian red scorpion venom and induced an increase in blood glucose level, organ tissue damage, necrosis, and pulmonary edema in Wistar rats, much better than commercial ASA, AAA, and vitamin C. The treatment holds promise for effective treatment against scorpion stings and will save the lives of millions of patients worldwide.Scorpion envenomation is a severe problem in many countries of the world. The Indian red scorpion (Mesobuthus tamulus), with its life-threatening sting, is one of the world's most dangerous scorpions. Intravenous administration of equine anti-scorpion antivenom (ASA), raised against M. tamulus venom (MTV), is the only available treatment for scorpion stings. However, the low proportion of venom-specific antibodies against the most abundant low molecular mass channel toxin is a barrier to efficient clinical management of scorpion sting patients. Therefore, the high antivenom requirement may lead to adverse serum reactions in treated patients. Scorpion envenomation and its treatment need extensive research and alternative therapies.
