Synergism between cyclopropenoid fatty acids and chemical carcinogens in rainbow trout (Salmo gairdneri).

Syiiergism between Cyclopropenoid Fatty Acids and Chemical Carcinogens in Rainbow Trout (Salmo gairdneri) 1.2

The synergistic activities of cyclopropenoid fatty acids (CPFA), epoxyoleic acid, sesame seed oil, and autoxidized salmon oil with aflatoxin Bt were studied in rainbow trout. Sterculia foetida oil (49% sterculic, 7% malvalic acids) and Hibiscus syriacus oil (2% sterculic and 19% malvalic acids) were used as sources of CPFA. The combination of both 112 and 56 ppm CPFA procured from S, foetida oi...

Cytoplasmic alterations of hepatocytes in rainbow trout (Salmo gairdneri) induced by cyclopropenoid fatty acids.

Molecular species composition of the major phospholipids in brain and retina from rainbow trout (Salmo gairdneri). Occurrence of high levels of di-(n-3)polyunsaturated fatty acid species.

The molecular-species compositions of the diacyl classes of the major phospholipids from the brain and retina of rainbow trout (Salmo gairdneri) were determined. A total of 46 possible species was identified. Didocosahexaenoyl species were major components of phosphatidylcholine (PC), phosphatidylethanolamine (PE) and phosphatidylserine (PS) from retina, comprising 14.1, 41.3 and 28.3% of the r...

Influence of thermal acclimation on membrane lipid composition of rainbow trout liver.

Rainbow trout (Salmo gairdneri) acclimated to 5 degrees C possessed larger livers and less neutral lipid per gram of liver than 20 degrees C-acclimated animals; quantities of liver glycolipid, phospholipid, and cholesterol did not vary significantly with acclimation temperature. The relative proportions of phosphatidylethanolamine increased significantly following cold exposure, whereas the qua...

Pituitary activation by bacterial endotoxins in rainbow trout (Salmo gairdneri).

Endotoxins from Escherichia coli and Aeromonas salmonicida caused marked cortisol production in the rainbow trout (Salmo gairdneri).
