Soyabean Oil Supplementation Effects on Perivascular Inflammation in Lungs Induced by Bisphenol A: A Histological Study.
J Coll Physicians Surg Pak Jan ;27(8):463-5.

Objective: To determine the effect of soyabean oil supplementation on perivascular inflammation in lungs of adult mice induced by Bisphenol A (BPA). Study Design: An experimental study. Place and Duration of Study: Department of Anatomy, Army Medical College, Rawalpindi, in collaboration with the Animal House, National Institute of Health, Islamabad, from June to November 2016. Methodology: Thirty male and female BALB/c mice were divided into three groups, of 10 animals each. Group A animals served as control. Group B animals were given BPA at a dose of 50 mg/Kg body weight/day. Group C animals were given BPA and soyabean oil at doses of 50 mg/Kg body weight/day and 500 mg/day, respectively. All treatments were given once daily for a period of eight weeks. Animals were dissected 24 hours after receiving the last dose. Lung tissue specimen processing and H&E staining was carried out for routine histological study. Perivascular inflammation was morphometrically graded and statistically analysed using Chi-square test with p<0.05. Results: Grade 2 inflammation was recorded in two (20%) animals and grade 3 perivascular inflammation in 80% specimens in Group B; whereas 20% specimens of Group C had grade 2 inflammation and eight (80%) showed grade 1 inflammation. None of the control animals showed any inflammation. All groups were significantly different at p<0.001. Conclusion: BPA produced perivascular inflammation and con-commitant administration of soyabean oil diet protected against it in rodent.
