“…Alkaline phosphatase, which plays a critical role in protein synthesis (Pilo et al, 1972), shell formation (Timmermans, 1969) and other secretory activities (Ibrahim et al, 1974) in gastropods and acid phosphatase, a lysosomal enzyme (Aruna et al, 1979) which plays an important role in catabolism, pathological necrosis, autolysis and phagocytosis (Abou-Donia, 1978) were also inhibited by the different treatments of P. granatum bark and C. indica root and their different combinations.…”

Sublethal in vivo 24 h exposure to (40% and 80% of 24 h LC(50)) active fractions of Punica granatum bark or Canna indica root or in combination with other plant-derived molluscicides significantly inhibited the activity of acetylcholinesterase, acid/alkaline phosphatase, Na(+)K(+)ATPase and lactic dehydrogenase in the nervous tissue of Lymnaea acuminata. The inhibition kinetics of these enzymes indicates that active fractions of both the plants caused a competitive inhibition of AChE, LDH, ALP, ACP and Na(+)K(+)ATPase.

“…19 The in vivo inhibition of LDH activity by sublethal doses of the above treatments indicates that the treatments act on the anaerobic metabolism. Alkaline phosphatase (which plays a critical role in protein synthesis, 20 shell formation 21 and other secretory activities 22 in gastropods) and acid phosphatase (a lysosomal enzyme 23 that plays an important role in catabolism, pathological necrosis, autolysis and phagocytosis 24 ) were also inhibited by treatment with oil of AI, CD, bulb powder of AS, NI and the combinations AS + CD and CD + AI.…”

Effect of single and binary treatments of plant-derived molluscicides on different enzymes--acetylcholinesterase (AChE), lactic dehydrogenase (LDH) and acid/alkaline phosphatase (ACP/ALP)--in the nervous tissue of the harmful terrestrial snail Achatina fulica were studied. Sublethal in vivo 24-h exposure to 40% and 80% LC(50) of Azadirachta indica oil, Cedrus deodara oil, Allium sativum bulb powder, Nerium indicum bark powder and binary combinations of A. sativum (AS) + C. deodara (CD) and CD + A. indica (AI) oils significantly altered the activity of these enzymes in the nervous tissue of Achatina fulica. The binary treatment of AS + CD was more effective against AChE, LDH, and ALP than the single ones. However, binary treatment of AI + CD was more effective against ALP.

“…The enzyme ALP plays a critical role in protein synthesis [36] and secretary activity [37] is comparatively less inhibited than AChE. Acid phosphatase (ACP), a lysosomal enzyme [38], plays an important role in autolysis and phagocytosis, pathological necrosis, and overall catabolism [8,10,39] was reduced significantly. Earlier, it has been observed that increased activity of ACP causes breakdown of existing protein in L. acuminata [18], but inhibition of ACP activity in this study indicates that it is not used in breakdown of cellular protein.…”

Earlier it has been observed that oleoresin of Zingiber officinale is a potent molluscicide against Lymnaea acuminata. This snail is the vector of Fasciola species, which cause endemic fascioliasis in eastern Uttar Pradesh. As this snail breeds and maintain their population constant through out the year, so that the present study has been designed to find out the effect of variations in some environmental factors in different seasons, on the molluscicidal activity of oleoresin of Zingiber officinale and its relative effect on certain enzymes viz., acetylcholinesterase, acid and alkaline phosphatases in the nervous tissue of the snail Lymnaea acuminata. In this study temperature, pH, dissolve oxygen, free carbon dioxide, conductivity of the water in control, as well as molluscicide treated water, was measured simultaneously. LC 50 value of oleoresin was determined in each month of the year. Toxicity of oleoresin in June-July (24 h LC 50 16.54-14.28 mgL -1 ) is highest. Acetylcholinesterase, acid and alkaline phosphatases activity in the nervous tissue of the snails treated with sub-lethal concentration of oleoresin was simultaneously measured. Sig-nificant positive rank correlation, in between the acetylcholinesterase or acid phosphatase activity and LC 50 of oleoresin was observed. The pre-sent study conclusively shows that variant abi-otic factors can significantly alter the toxicity of oleoresin of Z. officinale in L. acuminata. The most suitable period for control of L. acuminata is June-July.
