OBJECTIVE: To determine the effect of commercial green tea on ibuprofen-induced glomerular atrophy in kidney of adult rat by using transvertical glomerular diameter as the determining parameter.

STUDY DESIGN: Laboratory-based experimental study.

PLACE AND DURATION OF STUDY: Department of Anatomy, Army Medical College Rawalpindi in collaboration with National Institute of Health (NIH) Islamabad from December 2016 to January 2017.

METHODOLOGY: Thirty Sprague-dawley rats, males and females, were selected and divided into three groups. Each group comprised of 10 animals. Group A was used as control. Group B was given ibuprofen 120 mg/kg bodyweight/day. Group C received extract of Lipton green tea 1 ml/100 mg bodyweight/day in addition to ibuprofen 120 mg/kg. The dose was administered once daily for a period of 9 weeks. Animals were sacrificed 24 hours after administration of last dose. Kidney tissue was processed and stained with H&E. Routine histological study was performed. Change in transvertical glomerular diameter was taken as the defining parameter for determining glomerular atrophy. SPSS version 22 was the tool used for statistical analysis. P-value<0.05 was considered significant.

RESULTS: Transvertical glomerular diameter (TVGD) was significantly decreased in both experimental groups B (76.15 +1.85µm) and C (89.59 +1.87 µm) in comparison with control group A (94.27 +1.82 µm). However, the difference in TVGD between both experimental groups was also significant, asserting the ameliorative effect of green tea against glomerular damage.

CONCLUSION: Ibuprofen caused glomerular atrophy but administration of green tea along with ibuprofen protected against significant reduction in glomerular diameter, thus preventing atrophy.
