    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 M
    In 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.

    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 M
    The 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.

    STUDY OF BEHAVIOURAL RESPONSE OF AIR-BREATHING CATFISH MYSTUS CAVASISUS (HAMILTON) EXPOSED TO ELECTROPLATING INDUSTRIAL EFFLUENT CHROMIUM
    (Dr. Shashi Alok, Assistant Professor, Institute of Pharmacy, Bundelkhand University Jhansi (U.P.), India, 2011-07-01) Palanisamy P; Sasikala G; Mallikaraj D; Natarajan G M
    In the present experiment effect of electroplating industrial effluent chromium on the behavioral responses of freshwater air-breathing cat fish Mystus cavasius was studied. The toxicity of chromium to aquatic life is strongly influenced by the form of chromium and quality of water. The two most prevalent chromium forms found in plating industry waste water are hexavalent chromium (Cr+6) and trivalent chromium (Cr+3). The fishes exhibited various behavioral responses – locomotory, physiological, neurological and morbidity responses under influence of chromium industrial effluent. One of the major advantages of using data on behavioral effects is that they are more sensitive indicators of potential for impacts on survival in the filed than are measures of lethality. Study noted the possible utility of the behavior responses as rapid biomonitory assessment technique for qualitative evaluation of various industrial pollutants.

    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 M
    Effect 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.

    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 M
    Protein 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
