Kidney results. At the top Histological cuts of kidney, Hematoxilin-eosin stain. (A) EPA:DHA 1:1 in SHROB rat (40x) thyroidization zones are marked by black arrows. Thyroidization it’s a kind of atrophy which gives them the appearance of the follicles in the thyroid gland as we can see in the picture (hence the name). (B) EPA:DHA 1:2 in SHROB rat (200x), inflammation in kidney can be observed by the presence of inflammatory cells, also we can observe a normal glomerulus on the top and a glomerulus with glomerulosclerosis marked by a black arrow. At the bottom three graphics in which: (W) refers to Wistar strain, (S) refers to SHROB strain. (A) EPA:DHA 1:1, (B) EPA:DHA 2:1, (C) EPA:DHA 1:2. Equal letters, a, b, c, d, e means statistical differences among strains. (C) We found greater presence of glomerulosclerosis in SHROB rats than in Wistar rats, but significant differences were found only in the EPA:DHA 1:1 treatment (p = 0.005a). (D) SHROB rats had greater thyroidization than Wistar rats in all treatment groups p = 0.003a, p = 0.032b, p = 0.005c. (E) Atrophy was also higher in SHROB rats. EPA:1:1 doesn’t shown atrophy in either both treatments, but no significant differences were founded. (F) Inflammation were better also in EPA:DHA 1:1 treatments in both strains, but without significant differences.
