Mercuric chloride induced enzymological changes in kidney and ovary of a teleost fish,Channa punctatus

Abstract

The effect of LC(50) (1.8 MG/L) and a sublethal concentration (0.03 mg/L) of in vivo mercuric chloride exposure on the activities of acid and alkaline phosphatases, glucose-6-phosphatase, lipase and urease in the kidneys and ovaries of a teleost fish, Channa punctatus has been studied after 96 hr and 30 days respectively. It has been observed that the activities of all the enzymes except acid phosphatase were significantly inhibited in both the tissues. However, treatment for 96 hr resulted in more marked inhibition than 30 days of treatment. Acid phosphatase showed elevation in activity in the kidney after 96 hr of treatment.

Effect of Soft Cheese in Reducing of Lipid Profile and Liver Enzymes for Rats with Fat Disorder

“…The level of the enzyme AST and ALT increases during infection with viral hepatitis and other liver diseases accompanied by the occurrence of necrosis in the cells of the liver, as the level of the enzyme increases before the emergence of shows pathological symptoms to the equivalent of (10-100) once more than its normal rate and also increases its activity showily in some Conditions such as acute hepatitis 24 . The level of the ALP rises in a variety of conditions, including Cholestasis, Infiltrative liver disease, Partial and Total blockage of the bile duct, Pregnancy, Bone regeneration, Granuloma of the liver and Neoplastic liver disease, on the other hand, the increase in the concentration of basal phosphatase may It is because of the increased efficacy of Lysosomes, which is one of the important pre-cellular changes 25 . The results of group T2 indicate a decrease in the concentration of enzymes in the serum of the experiment rats, and the results of the study are consistent with what Mahmoud et al, 26 observed.…”

“…where 30 male rats (Rattus norvegicus) from the Sprague-Dawley strain at the age of 2-3 months and weights ranged between 205-215g. The experiment conditions were unified for all animals, where the room temperature was set between (23)(24)(25)°C by the use of an air conditioner, and the daily light period was 12 hours by the use of two fluorescent lamps, and the humidity rate was about 50 %. Food and water were provided daily (adlibitum).…”

Assessment of the interaction between microorganism and chemical mixture using resazurin reduction

“…The conventional toxicity bioassay using animals is time-consuming and expensive to perform. Thus, a wide range of short-term bioassays employing algae, bacteria, fish, invertebrates, and protozoan has been developed to meet the demand for rapid screening procedures of toxicity assessment (Wong et Rib0 and Kaiser, 1983;Sastry and Agrawal, 1979;van Dijk et al, 1977;Honig et al, 1980). Bacteria are particularly suitable for use in the rapid screening of chemical toxicity, mainly due to their easy handling, speed, and lower cost (Mowat, 1976).…”
