Serum markers. BUN and creatinine values were similar among the experimental groups throughout the study (BUN: p = .254; creatinine: p = .601, n = 4–5). AST showed a modest difference between the 100 million cells per milliliter and control groups and the 50 million cells per milliliter (∗) (p = .039, n = 4–5; and p = .048, n = 5, respectively). No change was seen in ALT (p = .061, n = 4–5). The hemoglobin (Hgb), red blood cell (RBC) count, total white blood cell (WBC) count, and lymphocyte counts were similar among the groups throughout the study (Hgb: p = .927; RBC count: p = .569; WBC count: p = .089; and lymphocyte count: p = .100; n = 4–5). Abbreviations: ALT, alanine transaminase; AST, aspartate aminotransferase; BUN, blood urea nitrogen; M, million.
