Abstract

Recent studies have shown that Plumbum could disrupt tissue prooxidant/antioxidant balance. The green tea leaves (Camellia
sinensis) is an antioxidant scavenger of free radicals and chelator of heavy metals. This study was designed to know and investigate the
efficacy of Katekin from green tea leaves malondialdehid (MDA) and superoxide dismutase (SOD) activity in erythrocytes caused by oral
Pb administration in Wistar rats. Thirty adult male rats were divided into six (6) groups (each groups: 5 rats): K+ group (oral 33.75
mg/bw Katekin), K group as a normal control, K- group (oral 15.82 mg/day lead acetate), P1 group (oral 22.5 mg/bw Katekin and 15.82
mg/day lead acetate, P2 group (oral 33.75 mg/bw Katekin and 15.82 mg/day lead acetate for), and P3 group (oral 45 mg/bw/Katekin
and 15.82 mg/day lead acetate) for 4 weeks. The results showed that Pb exposure induced the raised of MDA levels and decrease SOD
activity in erythrocytes of rats. The administration of Katekin from green tea leaves significantly reduced MDA levels and increased SOD
activity in Pb exposed erythrocytes of rats. The optimal dose of Katekin from green tea leaves as a scavenger of free radicals and chelator
of heavy metals was 22.5 mg/bw/day (P1). These results indicated that the administration of Katekin from green tea leaves may have
an important role in modulating oxidative stress in Pb exposed erythrocytes, but at a higher concentration of Katekin from green tea
leaves showed prooxidant activity.
