2.7. Estimation of Lipid Peroxidation
Uterine tissue was taken in 5 mL of Hank's balanced salt solution (HBSS, pH 7.4) and homogenized at 5000 rpm, using a Polytron homogenizer (3 cycles of 30 sec each; Kinematica, Switzerland). The homogenate was then centrifuged at 3500 rpm for 10 minutes (min). The pellet was resuspended in 0.1 mL of HBSS and used for estimation of lipid peroxidation. Lipid peroxidation was measured in terms of malondialdehyde (MDA) : thiobarbituric acid (TBA) reaction as reported by Ohkawa et al. [19]. The reaction mixture contained 0.1 mL of tissue homogenate (as described above), 0.2 mL of 8.1% sodium dodecyl sulphate, 1.5 mL of 20% acetic acid (pH adjusted to 3.5 with 1 M NaOH), and 1.5 mL of 0.8% aqueous solution of TBA.
