Effects of exercise on platelet and aortic functions in aged rats.
    Acta physiologica Scandinavica, 2003, Volume: 179, Issue:2

    To assess age- and exercise-related changes in platelet aggregation, we measured the magnitude of platelet aggregation with a four-channel aggregometer, plasma and aortic polyunsaturated fatty acids by gas chromatography and related prostanoids with a reagent kit in young and aged non-exercised and in aged exercised rats.. Platelet aggregation in platelet-rich plasma induced by ADP (5 microm) in the primary wave increased with age. In the non-exercised groups, the basal levels of thromboxane B2 in platelet-rich plasma increased in aged rats compared with young rats. In aged exercised rats, the basal levels of 6-keto-prostaglandin F1alpha in platelet-rich plasma were stimulated and those of thromboxane B2 were depressed, compared with non-exercised aged rats. The plasma levels of eicosapentaenoic acid and docosahexaenoic acid increased with age. Only aortic eicosapentaenoic acid in the aged group increased by exercise. In the aged non-exercised and exercised groups, the aortic, but not the plasma, levels of eicosapentaenoic acid correlated inversely with the basal levels of thromboxane B2 in platelet-rich plasma (r = -0.53, P < 0.05) and associated negatively with the magnitudes of platelet aggregation induced by ADP (5 microm) (r = -0.47, P < 0.05).. These findings suggest that exercise in aged rats increases aortic eicosapentaenoic acid concentrations, which in turn depress the basal levels of thromboxane, B2 in platelet-rich plasma to modulate platelet aggregation.

Effect of eicosapentaenoic acid ethyl ester on albuminuria in streptozotocin-induced diabetic rats.
    Journal of nutritional science and vitaminology, 1994, Volume: 40, Issue:1

    Wistar rats (4-week-old) were administered with streptozotocin (45 mg/kg) through tail veins. After 3 months, diabetic rats were divided into 2 groups. One group (EPA group, n = 16) was fed a lipid-free diet (90%, w/w) plus lard (8%) and 90% pure eicosapentaenoic acid ethyl ester (2%) for 6 months. The other group (control group, n = 16) was fed in the same way except that eicosapentaenoic acid ethyl ester was replaced by safflower oil. Twenty-four-hour urine was collected just before starting the experimental diets and during the 6-month experimental period at monthly intervals. There were no differences in food intake and body weight between the two groups throughout the experiment. The mean microalbuminuria of the EPA group became significantly lower than that of the control group after 4 months on the diets through the end of the study (6 months). The mean microalbuminuria levels at the end of the study were 1.38 mg/day in the EPA group (n = 9) and 5.19 mg/day in the control group (n = 6) (p < 0.01). Eicosapentaenoic acid administration might retard the progression of diabetic nephropathy by reducing microalbuminuria.

Effects of fish oil on gastric mucosal 6-keto-PGF1 alpha synthesis and ethanol-induced injury.
    The American journal of physiology, 1989, Volume: 257, Issue:1 Pt 1

    Fundic mucosal content and synthesis of 6-ketoprostaglandin F1 alpha, the major prostanoid in the rat gastric mucosa, were determined after rats had ingested a diet containing 10% fish oil or 10% corn oil for 4 wk. 6-Ketoprostaglandin F1 alpha content and synthesis in rats fed a fish oil-supplemented diet were reduced significantly compared with rats receiving a corn oil-supplemented diet (P less than 0.05). However, rats receiving 10% fish oil for 8 wk sustained significantly less gastric mucosal injury after intragastric challenge with 15% and then with absolute ethanol than rats receiving 10% corn oil or regular chow for 8 wk (P less than 0.05). Thus fish oil ingestion protected the gastric mucosa even though fish oils reduced mucosal prostaglandin synthesis.
