Data are expressed as mean ± SD of ten rats in each group. Values of lactate dehydrogenase isoenzyme (LDH₁) are expressed as U/mL. P is level of significance, where P < 0.0001 is significant. Analysis of data is carried out by one way (ANOVA) (analysis of variance) accompanied by post hoc (LSD) (least significant difference) (SPSS computer programme). Ext₁ means CCl₄ + Me-OH extract of Juniperus phoenicea leaves and Ext₂ means CCl₄ +Me-OH extract of Cupressus sempervirens. NS: Not significant.
