Protective effects of Sodium Tetraborate on fatty acid profiles in rat hearts subject to Lead toxicity; [Efecto protector del tetraborato de sodio sobre los perfiles de ácidos grasos en el corazon de ratas, expuestas a toxicidad por plomo]

This study was designed to observe the effects of sodium tetraborate on preventing lead metal toxicity damage to fatty acids in rat heart tissue. After the heart tissues were homogenized with Tris-HCl buffer, the separated pellet part was prepared for fatty acid analysis. The fatty acids in the obtained lipid extract were converted to methyl ester form and analyzed with SHIMADZU GC 2010 PLUS gas chromatography. When comparing the lead group with the lead + sodium tetraborate group, partial increases were observed in saturated fatty acid levels such as myristic acid (14:0), pentadecanoic acid (15:0), and palmitic acid (16:0), while varying increases were seen in some monounsaturated fatty acid levels such as palmitoleic acid (16:1, n-7), and oleic acid (18:1, n-9). Moreover, demonstrated varying levels of increases in all polyunsaturated fatty acids excluding the arachidonic acid (20:4, n-6) and adrenic acid (22:4, n-6) fatty acids. As the most notable fatty acid change in our study, arachidonic acid (20:4, n-6) fatty acid increasing in the lead group while decreasing in the sodium tetraborate group demonstrates that sodium tetraborate decreased the negative effects of oxidative stress on fatty acids. The results of this study provide supporting evidence for the potential use of sodium tetraborate in drug design to prevent the toxic effects of lead.
