Fig. 4. Effect of BA on AChE activity in serum samples following treatment with TMT. Animals were treated with different doses of BA (40, 80 and 160 mg/ kg) after they had been treatment with TMT at 8 mg/kg. Data are expressed as the means ± SD (n = 8). ^**P < 0.01 compared with the control group; ^†P < 0.05 and ^††P < 0.01 compared with the TMT-treated + saline group.

BA, boswellic acid; AChE, acetylcholinesterase; TMT, trimethyltin; SD, standard deviation.
