Sterile inflammation (SI) is an essential process in response to snakebite and injury. The venom induced pathophysiological response to sterile inflammation results into many harmful and deleterious effects that ultimately leads to death. The available treatment for snakebite is antiserum which does not provide enough protection against venom-induced pathophysiological changes like haemorrhage, necrosis, nephrotoxicity and often develop hypersensitive reactions. In order to overcome these hindrances, scientists around the globe are searching for an alternative therapy to provide better treatment to the snake envenomation patients. In the present study TiO (Titanium dioxide)-NPs (Nanoparticles) has been assessed for antisnake venom activity and its potential to be used as an antidote. In this study, the synthesis of TiO-NPs arrays has been demonstrated on p-type Silicon Si < 100 > substrate (∼30 ohm-cm) and the surface topography has been detected by Field-emission scanning electron microscopy (FESEM). The TiO-NPs successfully neutralized the Daboia russelii venom (DRV) and Naja kaouthia venom (NKV)-induced lethal activity. Viper venom induced haemorrhagic, coagulant and anticoagulant activities were effectively neutralized both in in-vitro and in vivo studies. The cobra and viper venoms-induced sterile inflammatory molecules (IL-6, HMGB1, HSP70, HSP90, S100B and vWF) were effectively neutralised by the TiO-NPs in experimental animals.

The rise of multidrug-resistant pathogens has become a serious health concern, creating an urgent need for novel therapeutic approaches. Among the compounds explored, AMPs have emerged as promising candidates due to their broad-spectrum activity and low propensity for resistance development. However, their clinical implementation is limited by improper size, in vivo instability, and toxicity.

The Deinagkistrodon acutus is the most widely distributed venomous snake in China, and its clinical manifestations are primarily characterized by hemorrhage and coagulation disorders. Previous studies have suggested that mesenteric vascular injury induced by Deinagkistrodon acutus venom may be the primary cause of hemorrhage in envenomation. Protease-activated receptor 1 (PAR1) is highly expressed in vascular tissues and plays an important role in regulating the structure and function of blood vessels.

In recent years, global climate change has caused fluctuations in the quantity and activity of phospholipase and proteases prevalent in animal venoms, leading to changes in the patterns of toxic animal injuries and increased treatment difficulties. Herein, this study conducted a screening for inhibitors of jellyfish venom enzyme activity and unexpectedly discovered that Salvianolic acid B (SaB) can inhibit the activities of phospholipase A (PLA) and proteases in jellyfish venom. Compared to protease inhibitor mixtures, this co-inhibition exhibited a more pronounced protective effect on the hemocyte, with 300 μM SaB reducing the hemolytic activity of jellyfish venom from 85 % to 57 %.

Introduction: Early diagnosis of systemic snake envenoming is essential for prompt antivenom treatment. The commonly used 20-min whole blood clotting test has poor sensitivity. We investigated the diagnostic utility of non-specific systemic symptoms alone or with the 20-min whole blood clotting test in detecting Russell's viper () envenoming following a snakebite.

Introduction: Toxic liver damage due to exposure to poisons, including those of animal origin, is often associated with lymphocytic infiltration, and the nature and degree of inflammation determine the rate of progression and severity of damage. The mechanisms by which toxic compounds activate immune-mediated pathways of liver damage are still being actively studied, however, liver infiltration by effector lymphocytes is a common phenomenon, leading to the destruction of hepatocytes and cholangiocytes and a persistent shift in the structural and functional characteristics of the organ Aim of study: To determine the features of the effect of scorpion venom on the immune defense system of the mammalian liver.
Materials And Methods: A thorough literature analysis was conducted on the basis of PubMed, Google Scholar, Web of Science, and Scopus databases.
