Modifying influence of polyphenols on hematotoxicity, cardiotoxicity, and hepatotoxicity induced by liquefied petroleum gas in rats.

Objective: This study was designed to investigate the effects of liquefied petroleum gas (LPG) on hematotoxic, cardiotoxic, and hepatotoxic indices and the modifying influence of selected polyphenols.

Methods: Adult male Wistar rats were exposed to1000 ppm LPG for 10 min at 12-h interval for 30 days with or without cotreatment with 50 mg/kg rutin, quercetin, tannic acid, or gallic acid followed by hematological, biochemical, and histopathological evaluations in animal tissues.

Results: Exposure to LPG induced hematotoxicity, cardiotoxicity, and hepatotoxicity. This is reflected in alterations to levels or activities of blood parameters (hemoglobin, packed cell volume, red blood cells, mean corpuscular volume, mean corpuscular hemoglobin, and platelets), enzymatic and nonenzymatic oxidative stress markers, nitrite, lactate dehydrogenase, creatine kinase-MB, transaminases, γ-glutamyl transpeptidase, bilirubin, and plasma albumin. LPG exposure also caused dyslipidemia and histoarchitectural changes. Treatment with the selected polyphenols effectively attenuated LPG-induced toxicity in rat tissues.

Conclusion: The results indicate that continuous exposure to LPG could lead to blood-, heart-, and liver-related diseases and dietary polyphenols could provide benefits in diseases associated with LPG inhalation toxicity.
