    HAEMATOLOGICAL CHANGES OF FRESH WATER FOOD FISH, CHANNA STRIATA ON EXPOSURE TO CLEISTANTHUS COLLINUS SUICIDAL PLANT EXTRACT
    (Dr. Sridevi M, India, 2011-04) Palanisamy P; Sasikala G; Mallikaraj D; Bhuvaneshwari N; Natarajan G M
    The freshwater fish Channa striata were exposed to lethal concentration of Cleistanthus collinus plant extract (10 mg L-1) 48 h. At the end of the 48 h exposure period, blood samples were taken from the control and experimental fish. Blood was assayed for selected haematological parameters (haematocrit, haemoglobin, red blood cell counts, white blood cells counts and erythrocyte sedimentation rate). The derived haematological indices of mean corpuscular volume (MCV), mean corpuscular haemoglobin (MCH) and mean corpuscular haemoglobin concentration were calculated. Significant decreases observed RBC (P<0.05), Hb content (P<0.01) PCV (P<0.01) WBC (P<0.05) were observed during the exposure period.

    ACETYLCHOLINE ESTERASE, ACETYLCHOLINE, SUCCINIC DEHYDROGENASE AND LACTIC DEHYDROGENASE CHANGES IN THE FRESH WATER FOOD FISH CHANNA STRIATA AFTER EXPOSURE TO CLEISTANTHUS COLLINUS SUICIDAL PLANT EXTRACT
    (Global Research Online, Bangalore, India, 2011-07-01) Palanisamy P; Mallikaraj D; Sasikala G; Natarajan G M
    Abstract: The enzymes Acetylcholinesterase (AchE), Acetylcholine (Ach), Succinic dehydrogenase (SDH) and Lactatedehydrogenase (LDH) are used as biological markers in the present study. Enzymes are highly sensitive and used to evaluate the biological effects of suicidal plant extract Cleistanthus collinus in freshwater food fish Channa striata. A significant increase in the Ach, LDH and SDH activity in muscle, liver and gill were observed. The AchE activity significantly declined by -49.80% liver, -45.00% gills and -38.03% in liver.
