“…Even at the lowest concentration (0.01mg/L NO 2 ), increase in glucose were detected in comparison with the control group (Kroupova et al, 2008). Hypoxia at tissue level affects the normal respiratory metabolism shifting it from aerobiosis to anaerobiosis (Philip et al, 1995;Smet and Blust, 2001) to supply greater energy for increased respiratory metabolism. Nitrite induced hypoxia, as indicated in the fingerlings, is therefore expected to increase the blood glucose.…”

Abstract:The aim of the present study was to evaluate about the glucose, glycogen content in liver and muscle in fresh water fish Cirrhinus mrigala exposed to nitrite toxicity. Plasma glucose level of Cirrhinus mrigala exposed to sublethal toxicity (28.31) of nitrite exhibited a significant increase throughout the study period (Table 20 and Fig. 19). The significant increase in plasma glucose level was directly proportional to the exposure period showing a minimum percent increase of 3. 69, 5.55, 13.34, 20.53

“…Increased activities of both transaminases indicated amplified transamination processes. An increase in transamination occurs due to amino acid input into the TCA cycle in order to cope with the energy crisis during pyrethroid-based stress (Philip et al, 1995).…”

469Cypermethrin is a widely used pesticide based on pyrethroids. It is among the most effective pyrethroid preparations (Bradbury and Coats, 1989a). The mechanism of its effectiveness in the case of fish is the same as that of other pyrethroids containing -cyano-3-phenoxybenzyl groups. They block the sodium channels of nerve filaments, thereby lengthening their depolarisation phase; moreover, they affect the GABA receptors in the nerve filaments (Bradbury and Coats, 1989b;Hayes, 1994).Cypermethrin is a synthetic pyrethroid used for the control of ectoparasites which infest cat- ABSTRACT:The aim of this study was to assess the effect of cypermethrin [(R,S)-α-cyano-3-phenoxybenzyl (1RS)--cis,tra-3-(2,2-dichlorovinyl)-2,2-dimethyl cyclopropane carboxylate] on rainbow trout (Oncorhynchus mykiss). The effect was assessed on the basis of the results of acute toxicity tests and on the comparison of results of haematological, biochemical and histopathological tissue examinations of a control and experimental group exposed to Alimetrine 10 EM pesticide preparation (active substance 100 g/l of cypermethrin). The acute semistatical toxicity test lasting 96 h was performed on rainbow trout juveniles. The 96hLC50 value of Alimethrine 10 EM was 31.4 µg/l. Examination of erythrocyte, leukocyte and biochemical profile and histopathological tissue examination was performed on 15 control and 15 experimental specimens of one-to-two-year-old rainbow trout after 96 h of exposure to Alimetrine 10 EM in the concentration of 31.4 µg/l. The experimental group showed significantly higher values (P < 0.01) of plasma ammonia (NH 3 ), aspartate aminotransferase (AST), lactate dehydrogenase (LDH), creatine kinase (CK), lactate (LACT) and significantly lower (P < 0.01) values of alkaline phosphatase (ALP) compared to the control group. Also, a significant decrease in count of developmental forms of myeloid sequence, and segmented neutrophile granulocytes in the experimental group were found. Teleangioectasiae of secondary gill lamellae and degeneration of hepatocytes were observed with histopathological examination. No histopathological changes were demonstrated in tissues (skin, spleen, cranial and caudal kidney) of rainbow trout following exposure to cypermethrine. The cypermethrine-based Alimethrinee 10 EM pesticide preparation was classified among substances strongly toxic for fish.
