Effects of different products derived from fish oil on biochemical parameters. Animal groups were fed with HFD and divided into four groups. Oral oil administration was: A, sunflower oil; B, DSO; C, CDSO concentrated by urea complexation and D, CPUFA salmon oil concentrated by urea complexation. Fasting lipid profiles were measured; (a) serum HDL cholesterol concentration (HDL-c), (b) total cholesterol (T-Cho) levels, and (c) serum triglyceride concentration. Serum transaminases measured were: (d) serum glutamic oxaloacetic transaminase (GOT) and (e) glutamic pyruvic transaminase (GPT). All biochemical measurements were made after 4 h of fasting. Values are represented as mean ± SD, n = 8, * p < 0.05, by one-way analysis of variance (ANOVA) followed by Tukey post hoc test.
