Right here, we restricted our evaluation to drugs can stop TeNT activity also in number of ani assayed their activity in mice shows that 2LD50 of TeNT induces the development of for ethical reasons. Figure 3 i.p. inoculated together with the toxin to lead to generalized tetanus. Right here, we limited our analysis to Ebselen and EGA to lower the number of animals temic tetanus in a synchronous manner, with mice displaying the symptoms of sp for ethical reasons. Figure three shows that 2 LD50 of TeNT induces the development of paralysis inside a narrowsynchronous manner, with mice displaying the symptoms of spasticFigure systemic tetanus in a time window (black trace). At variance, the red traces of show that Ebselen or time window (black trace). At variance, the red traces of Figure 3A,B paralysis in a narrow EGA pre-treatment strongly protects mice from TeNT neurotox show that Ebselen or EGA a significant delay within the development of tetanus Notably, mice displayed pre-treatment strongly protects mice from TeNT neurotoxicity. symp Notably, mice displayed a when compared to mice substantial only within the development ofan attenuation in the severi injected delay with TeNT. Such tetanus symptoms when when compared with mice injected only with TeNT. Such an attenuation inside the severity of TeNT TeNT intoxication by Ebselen and resulted in a reduced all round death rate,all round death rate, intoxication by Ebselen and EGA also EGA also resulted within a decrease with survivor survivor animals totally recovering from symptoms in a few days. animals fully recovering from symptoms inside a few days.Figure three.
