[A],[B],[C]. Quantitation of externalization of phosphatidyl serine [A]; mitochondrial membrane potential [B] and fragmentation of chromosomal DNA[C] in embryonic stages, treated with pharmacological agents viz. Curcumin, Primaquine and Chloroquine for 48 hrs are shown. Data points in A, B, C represent mean ± SEM, with n = 3. *P<0.05 by Paired t-test versus untreated controls; **P<0.05 by Paired t-test versus untreated controls and *** P<0.05 by Paired t-test versus untreated controls [D] Quantitation of fragmentation of chromosomal DNA in embryonic stages, treated with LPPs for 48 hrs. Data points in D represent mean ± SEM, with n = 5.*** P<0.05 by Paired t-test versus untreated controls.
