    Effect of chittosan supplimentation on antitubercular drugs-induced hepatotoxicity in rats
    (Elseviar, 2006) Santhosh, S.; Sini, T.K.; Anandan, R.; Mathew, P.T.
    We have studied the protective effect of chitosan on isoniazid- and rifampicin-induced hepatotoxicity with respect to the changesin the levels of diagnostic marker enzymes (in serum), lipid components and lipid peroxidation (in serum and liver). The oraladministration of antitubercular drugs caused a significant elevation in the levels of diagnostic marker enzymes and cholesterol, triglycerides, free fatty acids and lipid peroxidation in serum and liver of experimental rats. There was a slight decline in thelevel of phospholipids in liver tissue also observed.Co-administration of chitosan significantly prevented the antitubercular drugsinducedelevation in the levels of serum diagnostic marker enzymes (alanine amino transferase, aspartate amino transferase, lactatedehydrogenase, acid phosphatase and alkaline phosphatase) in experimental groups of rats. It exerted a significant antilipidemiceffect against isoniazid- and rifampicin-induced hepatitis by maintaining the levels cholesterol, triglycerides, free fatty acids and phospholipids in serum and liver at near normalcy. A tendency to prevent the isoniazid- and rifampicin-induced lipid peroxidationwas also observed. The results of the present study indicated that the hepatoprotective effect of chitosan might be ascribable to itsantilipidemic effect and/or antioxidant property

    Effect of essential oil and aqueous extract of ginger (Zingiber Officinale) on oxidative stability of fish oil-in-water emulsion
    (OMICS International, 2015) Jeyakumari, A.; Venkateshwarlu, G.; Choukse, M.K.; Anandan, R.
    Fish oil-in-water emulsion (5%) was prepared with essential oil and aqueous extract of ginger (Zingiber officinale) rhizome and their oxidative stability was examined. Antioxidant activities of essential oil and aqueous extract of ginger revealed total phenolic was high in essential oil (130.70 mg Catechol equivalents /l) than aqueous extract (24.38 mg Catechol equivalents /l) at 5% concentration. Chemical composition of Ginger (Zingiber officinale) essential oil was determined by GC-MS analyses showed Ginger essential oil contained, zingiberene (27.45 ± 0.30%), copaene (13.82 ± 0.06%), camphane (11.10 ± 0.16%), geranial (10.98 ± 0.10), as the major compounds. Oxidative stability test (thiobarbituric acid reactive substances) revealed that, In oil-in water emulsion, essential oil (1%) and aqueous extract (20%) together acted more significantly (p<0.05) against lipid oxidation (9.21 m mol O2/kg and 3.02 mg malonaldehyde/l) than control (21.33 m mol O2/kg and 4.31 mg malonaldehyde/l). Results from the study indicate that both essential oil and aqueous extract of ginger can be utilized together as a source of natural antioxidant to inhibitive action on fish oil-in-water emulsion.

    Myctophids: An alternate protein source from deep sea
    (Society of Fisheries Technologists (India), 2012) Mahato, P.K.; Baby, L.; Sankar, T.V.; Anandan, R.; Vijayan, P.K.; Ninan, G.; Zynudheen, A.A.
    Dietary deficiency of protein and consequent malnutrition is a significant problem especially in developing countries. Many of the vegetable protein lack certain essential amino acids, unless supplemented from other sources. Animal protein is superior in this respect but is comparatively expensive. It is in this context, fish and other marine products have great significance as a source of high quality protein which is at the same time less expensive. But in present scenario major fisheries of the world are either overexploited or getting exhausted to a point of no return which poses a serious threat to the future of our food security in terms of protein requirement. As efforts are already being made to revive the world fish catch, it is time to start looking for other untapped resources from the oceans. One such promising potential resource is Myctophids. Myctophids are commonly known as Lantern fishes falling under the Order Myctophiformes and belonging to the family Myctophidae which comprise of 235 species in 32 genera (Nelson, 1994). They are found in all oceans from the Arctic to the Antarctic and live at depths up to 1200 m. Some species make daily migrations up to 10 to 100 m. Most of the lanternfishes measure 6.5 to 10 cm in length. They have large eyes and bear photophores. They feed on small prawns, copepods and other crustaceans and have a low fecundity, with the females producing about 100-2000 buoyant, pelagic eggs of size 0.7-0.9 mm (Balu and Menon, 2006). Myctophids are not of much commercial importance so far. Most of the post harvest activities are restricted to the laboratory trials with some exception in fish meal and oil production, which is carried out on commercial level.

    Nutraceutical and therapeutic applications of squalene
    (Society of Fisheries Technologists (India), Cochin, 2018) Sumi, E.S.; Anandan, R.; Rajesh, R.; Ravishankar, C.N.; Mathew, S.
    Squalene, an isoprenoid molecule present in large quantities in deep sea shark liver oil and in smaller amounts (0.1-0.7%) in palm, wheat-germ, olive and rice bran oils, is well known for its antilipidemic, antioxidant and membrane stabilizing properties. Squalene is a key precursor molecule in the biosynthesis of vitamins, cholesterol and steroid hormones in animals. In human, presence of this highly unsaturated hydrocarbon keeps the skin healthy and protects it from ultraviolet radiations mediated carcinogenesis. Recently, squalene has drawn major attention as high valuable compound due its potential applications in the field of pharmacological, cosmetic, and nutraceutical industries. The present review includes a brief description about the natural sources, properties and applications of squalene.

    Quality evaluation of fish soup powder supplemented with carrageenan
    (2016) Jeyakumari, A.; Christin Joseph; Zynudheen, A.A.; Anandan, R.
    Carrageenans are widely utilized in food industry because of their physical and functional properties. In the present study, carrageenan was extracted from red seaweed and it was tested for the possibility for making healthy and nutritious fish soup for human consumption. The spray dried carrageenan powder had a protein, ash content of 12.12%, 34.53% respectively. Fish soup powder was prepared with the addition of 5% carrageenan powder and their nutritional properties were evaluated. Fish soup powder contained corn flour was served as control. Results suggested that fish soup powder can be prepared with the supplementation of carrageenan at 5% level without affecting consistency and flavor characteristics of soup and thereby increase the nutritional value of healthy soup for human consumption.

    Supplementation of squalene attenuates experimentally induced myocardial infraction in rats
    (Elsevier, 2007) Farvin, K.H.S.; Kumar, S.S.; Sankar, T.V.; Anandan, R.; Mathew, S.; Nair, P.G.V.
    We have investigated the preventive effects of squalene against isoprenaline-induced myocardial infarction in male albino rats. Supplementation with squalene significantly prevented the isoprenaline-induced adverse changes in the levels of protein and glycoprotein components in plasma and heart tissue of experimental groups of rats. It exerted an antioxidant effect by inhibiting the isoprenalineinduced lipid peroxidation and by maintaining the level of non-enzymatic free radical-scavenger, reduced glutathione at near normalcy. Histopathological observations also confirmed the possible cardioprotective action of squalene by maintaining the normal architecture of the heart tissue. The results of the present investigation demonstrate that supplementation with squalene offers cardioprotection in experimental rats by its antioxidant and membrane- stabilizing properties.
