The effect of biopesticide - Derisom on certain metabolites and enzymes of carbohydrate metabolism were evaluated in gill, liver, kidney and muscle of Cyprinus carpio during sub-lethal toxicity exposure of 21 days. A dose of 0.28 ppm was taken as the sub-lethal dose. The organs were taken from exposed and control fish at the end of 24 hrs, 7, 14 and 21 days and used for the estimation of total ...

Toxins produced by staphylococci and enterobacteria isolated from the nasopharynx of cases of sudden infant death syndrome (SIDS) have a lethal effect when injected into chick embryos. If the toxins are progressively diluted the lethal effect disappears, but certain combinations of toxins show synergy so that if sublethal doses are mixed a highly lethal effect is produced. In this paper it is s...

The purpose of this study was to examine the acute and sub-acute effects of diazinon onhistopathological parameters of liver tissue and blood level of hepatic enzymes of male commonfrog (Rana ridibunda). Frogs were assigned to 9 groups (n=8, meaning 8 frogs in each group):control and treatment groups with 30, 60, 90 and 120 μg/L diazinon in water for one day or oneweek. Hepatic enzymes containi...

Received August 26. 1964 A large number of both spontaneous and induced second chromosome recessive lethals in Drosophila melanogaster have been reported. Almost of all these lethals are rather rapidly eliminated from populations under random mating conditions. IVES (1945) and WALLACE (1950) have estimated the number of second chromosome loci of lethal genes as 495 and 400, respectively. Some l...

Fasciolosis is a cosmopolitan parasitic disease with considerable economic and public health importance. Fasciola hepaticais the major cause of fasciolosis in man and domestic animals. Although remarkable research works have been done around the optimum temperature and time required for miracidial development, little is known aboutthe exact susceptibility of Fasciola hepaticaeggs to high temper...

in present study, it was determinated lc50 96-h and toxicity degree of diazinon in huso huso, then were evaluated effects of sub-lethal concentrations on tow general enzymatic indices including alanine and aspartate aminotransferase of plasma and one specific enzymatic index including tissue ache enzyme. the median lethal concentration, lowest observed effect concentration and maximum allowable...
