Assessment of Subacute Toxicity of Ulexite in Rats: Behavioral, Hematological, and Biochemical Insights.

Abstract

Ulexite (UX), a naturally occurring borate mineral, has gained interest for its diverse industrial applications, yet its toxicological profile remains inadequately characterized. This study aimed to evaluate the subacute toxicity of UX in rats, focusing on behavioral, hematological, and biochemical parameters. Rats were administered UX via gavage at doses of 10, 30, and 300mg/kg for 7days. No mortality or significant signs of toxicity were observed, although body weight measurements indicated a notable reduction in the UX-treated groups compared to controls. Behavioral assessments demonstrated increased exploratory activity in the 10 and 300mg/kg UX treated groups, suggesting low anxiety levels. Likewise, hematological analysis revealed that 30 and 300mg/kg UX led a significant (P < 0.001) increase in hematocrit and a decrease in mean corpuscular hemoglobin concentration (P < 0.001), indicating potential changes in erythropoiesis. Additionally, serum biochemistry showed elevated aspartate aminotransferase (P < 0.05), lactate dehydrogenase (P < 0.001), and uric acid levels (P < 0.01), suggesting liver stress. Histopathological examinations indicated dose-dependent alterations, with mild hepatocellular degeneration and neuronal changes observed at the highest dose. Also, MN levels in the blood of rats exposed to 10 and 30mg/kg UX showed no significant differences. These results suggest that UX is relatively safe at lower doses, though higher exposures may pose health risks. Further research is warranted to elucidate the mechanisms underlying UX-induced effects and to evaluate its safety for therapeutic and occupational applications.
