Aims: To study the protective effect of hydroalcoholic bark extract of Terminalia arjuna against DBTC induced pancreatic cancer in male wistar rats. Study design: Healthy male Wistar Albino rats weighing 150-200 g were segregated into four groups (n=6). Group I was considered as normal control, received normal saline (0.9%w/v, 1 ml/kg body weight, orally). Group II rats were treated with DBTC (6 mg/kg body weight, i.p.) which served as negative control. Group III and IV received Terminalia arjuna Linn bark hydroalcoholic extract at doses of 250 mg/kg body weight, per oral and 500 mg/kg body weight, per oral respectively. Place and Duration of Study: University College of Pharmaceutical Sciences, Andhra University, Visakhapatnam, Andhra Pradesh, India, between May 2020 and July 2020. Methodology: The experimental animals were segregated into four groups of six rats each. According to acute toxicity data, 250 mg/kg as low dose and 500 mg/kg as high dose of the test compound have been chosen for administration. All the drugs were given for 28 consecutive days to all the respective groups with standard pellet diet and water ad libitum. The assessment of serum parameters such as α-Amylase, Lipase and blood glucose levels were carried out on 1st day, 14th day and 28th day to the respective groups. Results: Pretreated groups of Terminalia arjuna Linn bark hydroalcoholic extract (250 mg/kg and 500 mg/kg body weight, orally) showed significant (‘#’p<0.001) decrease in the levels of α-Amylase, Lipase and glucose in the blood when compared to DBTC (6 mg/kg body weight, i.p.) induced group which served as negative control. Conclusion: This study suggests that Terminalia arjuna may have a protective role against DBTC induced pancreatic cancer in male wistar rats and further investigation may be required to confirm its therapeutic potentials clinically.

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.
