Item ACTIVITY LEVELS OF PHOSPHATASES OF THE AIR-BREATHING CATFISH MYSTUS CAVASIUS EXPOSED TO ELECTROPLATING INDUSTRIAL EFFLUENT CHROMIUM.(BLM, International, Open-Access Journal, 2012-07-01) Palanisamy P; Sasikala G; Mallikaraj D; Bhuvaneshwari N; Natarajan G MIn India chromium is widely used in all electroplating industries. Chromium in electroplating industrial effluent has been shown to inhibit many enzymes at different segments of metabolism. Chromium especially inhibits pyruvate oxidases system and phosphatases. The present study was undertaken to evaluate the effect of effluent chromium on phosphatases on exposure to sub-lethal concentration (0.25%) for a period of 24, 48, and 72 h and 15 d. Activity levels of acid phosphatase and alkaline phosphatase decreased significantly in the gill and air bladder tissues of experimental catfish, Mystus cavasius, when compared with that of controls.Item HISTOPATHOLOGICAL LESIONS IN GILL OF AIR-BREATHING CAT FISH MYSTUS CAVASIUS EXPOSED TO ELECTROPLATING INDUSTRIAL EFFLUENT NICKEL(Fortune Journals, an open access publisher, 2011-04) Palanisamy P; Sasikala G; Mallikaraj D; Bhuvaneshwari N; Natarajan G MThe gill which participate in many important functions in fish, such as respiration, osmoregulation and excretion. Electroplating industrial effluent nickel induced hyperplasia, multiple telangiectases (aneurysms), desquamation of the epithelial cells, complete fusion of secondary gill lamellae and congestion of blood sinuses were the significant histopathological lesions observed in the gill of Mystus cavasius.Item EFFECT OF ELECTROPLATING INDUSTRIAL EFFLUENT CHROMIUM ON BIMODAL RESPIRATORY RHYTHM OF THE AIR-BREATHING CAT FISH MYSTUS CAVASIUS (HAM.)(BRNSS Publication Hub, Mandsaur University, Madhya Pradesh, India, 2011-03-10) Palanisamy P; Mallikaraj D; Sasikala G; Bhuvaneshwari N; Natarajan G MEffect of sublethal (0.25%) concentration of electroplating Industrial effluent chromium on bimodal respiratory rhythm of Mystus cavasius (Ham) was studied. Result revealed that at sublethal concentration the respiratory rhythm was significantly disrupted. The significance of the results is discussed from a chronotoxicological point of view.Item CHANGES IN PROTEIN CONTENT IN THE MUSCLE OF MYSTUS CAVASIUS (HAM.) EXPOSED ELECTROPLATING INDUSTRIAL EFFLUENT CHROMIUM(BRNSS Publication Hub, Mandsaur University, Madhya Pradesh, India, 2011-03-10) Palanisamy P; Sasikala G; Mallikaraj D; Bhuvaneshwari N; Natarajan G MProtein content in the muscle of Mystus cavasius (Ham) exposed to 1/3 of sublethal concentration of electroplating industrial effluent chromium (0.25%) for period of 30 days has been studied. After 24, 48, 72 h and 15 days of exposure the muscle showed significant depletion from -9.77%, -20.45%, -26.14% and -31.82% over the control
