ABSTRACT
Cypermethrin is a synthetic pyrethroid insecticide with low mammalian toxicity but high insecticidal activity. Following exposure to sublethal concentration of cypermethrin (1/10 LC50 1.63mg/l) in frogs, the haematological profiles were investigated over 7 days and 30 days. The results revealed statistically significant decrease of red blood cells, haemoglobin, packed cell volume, mean corpuscular volume, mean corpuscular haemoglobin, mean corpuscular haemoglobin concentration, and neutrophils, and increase of the other white blood cells, including lymphocytes, monocytes, and eosinophils.
ABSTRACT
Mg2 + dependent —adenosine triphosphatase activity has been studied in the muscle, brain, kidney and liver tissues of frog, Rana hexadactyla (Lesson) after sciatectomy and induced chronic ammonia stress. The enzyme activity decreased in the tissues of the denervated frog. The activity of the enzyme increased in all the tissues of the normal and denervated frogs except in the denervated muscle when ammonium lactate was infused intraperitoneally.
