BackgroundHeavy metals like lead (Pb) have been used by humans for a very long time, but throughout the industrial revolution, their use expanded, increasing exposure to the metal. Lead, however, has no biological purpose in the human body and is hazardous when it gets into soft tissues and organs. Lead is still used in a variety of industries, including battery manufacturing and car maintenance, despite efforts to limit its usage.ObjectiveThis study investigates the teratogenic and morphometric effects of lead on chick embryos and the potential ameliorative effects of vitamin B6.MethodsTwo hundred fertilized eggs from the golden black chicken were divided into four groups: control, lead acetate, vitamin B6, and lead + vitamin B6.ResultsOn the 14th day, embryos were analyzed. Significant reductions in body weight and size were observed in the lead‐exposed group (33.93 ± 1.27 g) compared to the control (41.12 ± 0.97 g). Pronounced deformities included rudimentary beaks, protruding eyes, tridactyl limbs, hydrocephaly, and neck deformities. Appendicular deformities like phocomelia, amelia, and abnormal phalanges growth were also noted. Vitamin B6 demonstrated therapeutic benefits, significantly improving mean embryo weight in the Lead + Vitamin B6 group (42.37 ± 0.99 g). The lead‐exposed group showed a reduction in maxilla length (3.61 ± 1.30 mm) compared to the Lead + Vitamin B6 group (7.57 ± 0.79 mm). This group also showed reduced severity of muscular dystrophy and bone thinning, with signs of recovery in beak and bone sizes.ConclusionsThe study highlights vitamin B6's beneficial impact in mitigating lead's toxic effects on chick embryonic development.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
