Abstract:RESUMOObjetivos: Avaliar o efeito da toxina botulínica do tipo A e da crotoxina na ativação de células satélites das fibras musculares de retos superiores de coelhos. Métodos: Os músculos retos superiores do olho direito de 29 coelhos machos albinos neozelandeses foram inoculados com toxina botulínica do tipo A ou com crotoxina, em diferentes doses. Os músculos retos superiores contralaterais de cada animal foram inoculados com solução salina em volume igual ao das toxinas. Os animais foram sacrificados 12, 18… Show more
Background:
The venom of Crotalus durissus terrificus, as well as its fractions, has intrigued research groups worldwide who are working to isolate, characterize, and find possible biotechnological applications. A number of studies have elucidated that these fractions and their derivatives possess pharmacological properties, which can enable the development of new drug prototypes with anti-inflammatory, antinociceptive, antitumor, antiviral, and antiparasitic applications.
Objective:
aspects, and applications of the main venom toxins (convulxin, gyroxin, crotamine, crotoxin, and their subunits).
Conclusion:
The authors have found that research on this snake and its toxins is still an area of focus, despite that almost a century has passed since the isolation of crotoxin. Several applications of these proteins in the development of novel drugs and bioactive substances have also been demonstrated.
