Abstract - Issue Mar 2009, 29 (2) BackHistoenzymological study
on the toxicity of copper sulphate in the digestive glands of Lymnaea luteola Sarvesh Mathur and Ashok

and Technology, (Received:
August 30, 2005 ; Revised received: March 26, 2006 ;
Re-revised received: August 18, 2006 ; Accepted: August 28, 2006) Abstract: During 24 and 48 hr of exposure, the digestive
glands of Lymnaea treated with a lethal concentration
of 0.038 mgl-1 CuSO4 revealed intense activity
of acid phosphatase in perilobular
margin. On the other hand, same
area of the gland showed moderate activity of ATPase
during 24 and 48 hr of exposure.
However, alkaline phosphatase showed average
activity in perialveolar region and perilobular margin during 24 and 48, and 72 hr of exposure
respectively. The changes in the
activity of these enzymes were nonsignificant in
alveolar margin and perialveolar region of the
gland. It is interesting to note
moderate activity of acid phosphatase in perialveolar region during 24 hr of exposure. Key
