Jamun seed and orange peel extracts protects effects of microcystin LR on serum calcium and phosphate of rats

Abstract

Wistar rats were treated as Group A: Control; Group B: microcystin LR (MCLR); Group C: microcystin LR and jamun seed extract (MCLR+JSE); Group D: microcystin LR and orange peel extract (MCLR+OPE); Group E: orange peel extract (OPE); Group F: jamun seed extract (JSE). MCLR dose was 10 µg/kg body wt/day whereas OPE and JSE dose was 200 mg/kg body wt/day. Serum calcium and phosphate were analyzed on 15 and 30 day. Serum calcium of rat exposed for 15 day to MCLR; MCLR+JSE and MCLR+OPE decreased. Although there is little increase in levels of group C and group D but treatment with OPE and JSE is not able to completely restore decreased calcium levels caused by MCLR. After 30 day calcium decreased after MCLR; MCLR+JSE and MCLR+OPE treatment. Levels in group E and F remain unaltered. Levels in group C and D exhibit elevation as compared to group B which indicates that treatment with OPE and JSE recovered calcium. Serum phosphate decreased after 15 day in MCLR; MCLR+JSE and MCLR+OPE treated rats. Phosphate levels of group C (compared with group F) and group D (compared with group E) show decrease. After 30 day exposure to MCLR; MCLR+JSE and MCLR+OPE phosphate levels decreased. Levels of group C and D when compared with group B are increased. Phosphate levels of group C (compared with group F) and D (compared with group E) are decreased. This indicates that OPE and JSE treatment provoked some recovery of phosphate levels.
