Heavy consumption of garlic (Allium sativum) exert nephro- and pulmonary toxicity at maternal and embryonic level in the Albino rats

Abstract

ABSTRACTDespite the health benefits of herbals, random misuse of such therapy without consult tends to participate in public health issues. This study describes the nephro-and pulmonary toxicity effects of heavy consumption of garlic (Allium sativum) during developmental period. Two groups of ten healthy pregnant female Albino rats each were formed from the 20 in total. Gavages of distilled water were administered to the control group. Since garlic group rats orally received garlic aqueous extract (GAE) 1 ml/rat daily from gestational day (GD) 6 to 19. Kidney functions and lipid biomarkers were assayed along with histopathological investigations. Our results confirmed that the group that received garlic had significantly increased serum levels of urea, cholesterol, triglycerides and LDL. Moreover, the foetal and maternal tissues of the kidney and lung exhibited a varying degree of histopathological manifestations characterized by kidney necrosis and lung haemorrhage, severe congestion, and thickening of the blood vessels. Renal and pulmonary fibrosis were detectable by Masson’s trichrome. A positive expression of the foetal kidney and placental tissues towards Bax protein was noticed. In conclusion, depending on existing findings, the administration of higher concentrations of garlic could explode renal and pulmonary toxicity and decrease the rat’s weight.
