| The freshwater bivalve Lamellidensmarginalis were exposed to acute and chronic dose of lambda cyalothrin (0.75 PPM LC50/2 valuesof 96 hours) and methomyl (35 PPM LC50/2 valuesof 96 hours) upto 96hours and 21 days alone and in combination with 50mg/L and 100mg/L L-ascorbic acid for 21 daysrespectively. Percent protein contents in the mantle, foot, gills, digestive glands, gonad and whole body of bivalve, Lamellidensmarginalis on methomyl and lambda cyalothrin intoxication and in combination with 50mg/L and 100mg/L L-ascorbic acid were observed. Protein contents in all soft body tissue of methomyl and lambda cyalothrin exposed bivalve, Lamellidensmarginalis showed remarkable decreasein protein content as compared to control.The higher depletion of protein was observed in digestive glands as compared to other tissues. Animal exposed to methomyl and lambda cyalothrin intoxication in combination with 50 mg/L of L-ascorbic acid showed considerable reduction in the depletion of protein levels which further improved on treatment with methomyl and lambda cyalothrin intoxication in combination with 100 mg/L of L-ascorbic acid. Fast recovery of percent protein contents was observed in presence of L-ascorbic acid than the recovery in the normal freshwater. This study indicates the protective and curative property of the L-ascorbic acid against methomyl and lambda cyalothrininduced damage. |
