Table 1 Values of total (number/mL) and differential (%) WBC in BALF of COPD treated with Z. multiflora , carvacrol, and dexamethasone (Dexa.)

From: Lung inflammation changes and oxidative stress induced by cigarette smoke exposure in guinea pigs affected by Zataria multiflora and its constituent, carvacrol

  1. Data are presented as mean ± SEM. WBC is expressed as its count in 1 mL BALF and those of each type of WBC is the percentage of total WBC. +; p < 0.05, ++; p < 0.01, +++; p < 0.001 compared to the effect of dexamethasone using unpaired t-test. #; p < 0.05, ##; p < 0.01. ###; p < 0.001, compared to the effect of low concentration of Z. multiflora and carvacrol, using (ANOVA) with Tukey–Kramer multiple post test.
