The experiment design and treatment doses used for TEO. CCl4; carbon tetrachloride, TEO; thymus vulgaris oil. 

Respiratory burst (A) phagocytic (B) serum lysozyme (C) and bactericidal activities (D) of albino male rats treated with thymus vulgaris oil (TEO2.5 (2.5 mg/ kg b.w) and TEO5 (5 mg/ kg b.w)) and CCl4 for 4 weeks. Data are expressed as Mean ± SEM. The different letters indicate significant difference (P < 0.05) between treated groups.

Data are expressed as Mean ± SEM. The different letters indicate significant difference (P < 0.05) between treated groups.
