A Histopathological Study of Cisplatin-induced Acute Vascular Injuries in Vital Organs and Protective Effect of Achillea millefolium

Abstract

The aim was to study the protective effect of ethanolic extract of Achillea millefolium on acute vascular injuries induced by cisplatin in liver, heart and renal tissues 24 hour after administration and using histopathological surveys in wistar rats. 24 adult male wistar rats were randomly divided into four groups. Group I (control group) received physiological saline for 10 days. Animals of group II had single dose of injection of CP (cisplatin) (6 mg/kg, IP) on the ninth day. Group III received Achillea millefolium extract (250 mg/kg, gavage) for 10 consecutive days. Group IV had both Achillea millefolium extract (250 mg/kg, gavage) for 10 consecutive days and a single dose of injection of CP (6 mg/kg, IP) on the ninth day. Kidney, liver and heart organs were collected on 10th day from sacrificed rats and subjected to histopathological analysis. Then the possible histopathological vascular effects of cisplatin on liver, heart, kidney tissues and the protective effect of Achillea millefolium extract was analysed. Obtained data showed the vascular injuries in CP group as congestion of cardiac capillaries (p=0.00) and interstitial edema (p=0.03). In the kidney, shrinkage of glomeruli (p=0.04), widening of Bowman's space (p=0.04), dilatation of cortical capillaries (p=0.01) were significantly altered. The findings of liver organ were increased sinusoidal space (p=0.00) and infiltration of neutrophils in portal space (p=0.01). Pretreatment with ethanolic extract of Achillea millefolium could attenuate these vascular injuries. Briefly, 24 hour after single injection of cisplatin the inflammatory process was seen in vital organs and administration of Achillea millefolium could mitigate these side effects.
