“…In the present study, SDH activity of muscle, liver and brain tissues of C. carpio was depleted with increasing sublethal concentration of distillery effluent as well as duration of exposure (Sambasiva Rao et al, 1986;Rajeswari et al, 1989). It could be attributed to decreased oxygen consumption under distillery effluent stress (O'Brien, 1967;Moorthy et al, 1985). It was concluded that fish chronically exposed to effluent appeared to affect the energy requirements by changing anaerobic oxidation.…”

The impact of distillery effluent on carbohydrate metabolism of Cyprinus carpio was studied at different days during exposure (7, 14, and 21 days) in the ambient temperature of 28 +/- 1 degrees C. Oxygen consumption in fish decreased with increasing effluent concentrations as well as duration of exposure. Effluent concentrations and exposure durations (days) had a significant effect on oxygen consumption of tested fish (p < 0.0005). Total carbohydrate, glycogen content and SDH enzyme activity in muscle, liver and brain tissues of C. carpio exposed to different sublethal concentrations decreased gradually and significantly. This was also the case with exposure duration. Reduction in glycogen content was greater in liver tissue i.e., 54.1% in 0.2% effluent concentration on the 21st day of exposure. However, serum glucose and lactic acid content showed an increasing trend with increase in effluent concentration and time of exposure. Unlike SDH, LDH enzyme activity of muscle, liver and brain tissues showed an increasing trend and the enhancement of enzyme activity was more in liver tissue (71.3%). From these results, it could be inferred that respiratory processes in C. carpio under distillery effluent stress was affected resulting in a shift towards anaerobiosis at organ level during sublethal intoxication.

“…Similarly, Rodriguez-Ariza et al (1993) found that G6PD activity was increased after pesticide toxicity in gray mullet (Mugil sp.). In another study, it was shown that G6PD activity was increased in gill of fresh water mussel, Lamellidens marginalis by MP (Moorthy et al, 1985).…”

Fenarimol and methyl parathion are pesticides that have been used in agriculture for several years. These pesticides have significant effects on environmental and human health. Therefore, we investigated the effects of methyl parathion and fenarimol on glucose 6-phosphate dehydrogenase (EC 1.1.1.49) enzyme activity in rats. The glucose 6-phosphate dehydrogenase is the first enzyme of the pentose phosphate pathway and it is important in detoxifying reactions by NADPH generated. In this study, wistar albino rats administrated with methyl parathion (7 mg kg -1 ) and fenarimol (200 mg kg −1 ) by intraperitoneally for different periods (2, 4, 8, 16, 32, 64, and 72 h). The glucose 6-phosphate dehydrogenase enzyme activity was assayed in liver, kidney, brain, and small intestine in male and female rats. The exposure of fenarimol and methyl parathion caused increase of glucose 6-phosphate dehydrogenase enzyme activity in rat tissues, especially at last periods. We suggest that this increment of enzyme activity may be the reason of toxic effects of fenarimol and methyl parathion.

“…Changes in the levels of aldolase, an enzyme involved in glycolytic (anaerobic) carbohydrate metabolism, have been observed in the digestive gland of infected snails (Marshall et al, 1974;Narayanan & Venkateswara Rao, 1981), whilst toxicant exposure can lead to an increase in aldolase activity in some uninfected molluscan species (Moorthy et al, 1985). Under the combined stress of toxicant and trematode parasite, Stadnichenko et al (1988) found that exposure of Planorbarius banaticus to nitroammophoska (a common fertilizer used in the former USSR) caused an increase in aldolase activity, which was significantly greater in snails infected with Cotylurus cornutus.…”

Pollutant-induced effects on immunological and physiological interactions in aquatic host–trematode systems: implications for parasite transmission

2006

Under conditions of pollution both host and parasite are susceptible to the pathogenic effects of toxicants, which in turn may result in detrimental changes to their immunological and physiological processes. Digenetic trematodes, which encompass species of both medical and economic importance, possess complex life cycles and are common parasites of both vertebrates and molluscs. The combined stress induced by pollution and parasitism influences the physiology of the host which can have implications not only on host survival but also on the functional biology of resident parasite populations. The present paper reviews the effects of pollutants on the immunology and physiology in both vertebrate and molluscan host-trematode systems and the implications for parasite transmission.
