    Our study has clearly shown that the oral administration of choline ascorbate, which contains approximately 500 mg of ascorbic acid to the volunteers causes an increase in the blood levels of ascorbic acid. This increase is statistically significant (p < 0.01) compared with the basal level each time. In the control group, vitamin C tablet also causes an increase in the blood level of ascorbic acid. However, this increase is less than that of the test group. Our results indicate that ascorbic acid, as a part of choline ascorbate molecule, reaches the blood circulation without losing its activity

    Aim: We investigated the vascular effects of agmatine (decarboxylated arginine = AGM), an endogenous ligand for alpha(2)-adrenoceptors and imidazoline receptors, present in endothelium and smooth muscle, using the diabetic rat aortae
