Figure 2

The histology of renal cells with H&E staining method of rats treated with 50 mg/kg, 300 mg/kg, and 2000 mg/kg of Piper sarmentosum aqueous extract and normal saline for 28 consecutive days at 25 and 200 times magnification. There were no significant changes in the structure of the kidney cells observed in the histological section of the kidney tissues of the treatment groups. G: glomerulus; BM: basement membrane; PCT: proximal convoluted tubule; DCT: distal convoluted tubule; C: cortex; M: medulla; BS: Bowman’s space.
