Effect of the carthamins yellow from Carthamus tinctorius L. on hemorheological disorders of blood stasis in rats

Hemorheological disorders may play an important role in the pathogenesis and development of many diseases. Blood stasis, i.e. the decrease of blood flow velocity, indicates hemorheological abnormalities. The carthamins yellow (CY), isolated from Carthamus tinctorius L., has been extensively used as a natural food colorant. We investigated the effects of CY on a blood stasis model, which was obtained by placing rats in ice-cold water during the time interval between two injections of epinephrine. The results demonstrated that the CY significantly decreased the whole blood viscosity, plasma viscosity, and erythrocyte aggregation index, which were increased in the blood stasis model. Hematocrit and platelet aggregation were reduced, while prothrombin time was delayed with increasing doses of CY. Therefore, CY administration might provide the additional benefit of increasing blood fluidity by lowering blood viscosity, which can be of great value in the prevention of hemorheological disorder-associated diseases in at risk patients. Meanwhile, the mild activities of antiplatelet aggregation and anticoagulation induced by CY should be considered, if these relatively untoward symptoms occurred when the hemorrhagic patients ate food colored by CY. However the small amounts used in food are highly unlikely to cause adverse effects.     

Effects of Hct on L-NAME-induced potentiation of anaphylactic presinusoidal constriction in perfused rat livers

Effects of hematocrit (Hct) on N-nitro-L-arginine methyl ester (L-NAME)-induced modulation of anaphylactic venoconstriction were determined in isolated perfused rat livers. The rats were sensitized with ovalbumin (1 mg), and the livers were excised 2 weeks later and perfused portally and recirculatingly under constant flow at Hct of 0%, 5%, 16%, and 22%. The hepatic sinusoidal pressure was estimated via the double occlusion pressure (Pdo), and the presinusoidal resistance (Rpre) and the postsinusoidal resistance (Rhv) were calculated. The antigen of ovalbumin 0.1 mg was injected into the reservoir at 10 minutes after pretreatment with L-NAME (100 microM) or D-NAME (100 microM). Perfusate viscosity, a determinant of vascular resistance and shear stress, was increased in parallel with Hct. In the D-NAME groups, antigen caused predominant presinusoidal constriction. The magnitude of venoconstriction was significantly smaller at Hct 0% than at Hct 5% to 22%, whereas no significant differences were found among Hct 5% to 22%. L-NAME potentiated the antigen-induced increase in Rpre, but not in Rpost at Hct 5% to 22% as compared with D-NAME. But the augmentative effects of L-NAME were similar in magnitude among Hct 5% to 22%. These findings suggest that hepatic anaphylaxis increases production of nitric oxide, which consequently attenuates anaphylactic presinusoidal constriction in rat livers, and that these effects are independent of perfusate Hct or viscosity in blood-perfused rat livers.     

Zn(II)–curcumin protects against hemorheological alterations,oxidative stress and liver injury in a rat model of acute alcoholism

Curcumin can chelate metal ions, forming metallocomplexes. We compared the effects of Zn(II)–curcumin with curcumin against hemorheological alterations, oxidative stress and liver injury in a rat model of acute alcoholism. Oral administration of Zn(II)–curcumin dose-dependently prevented the ethanol-induced elevation of serum malondialdehyde (MDA) content and reductions in glutathione level and superoxide dismutase (SOD) activity. Zn(II)–curcumin also inhibited ethanol-induced liver injury. Additionally, Zn(II)–curcumin dose-dependently inhibited hemorheological abnormalities, including the ethanol-induced elevation of whole blood viscosity, plasma viscosity, blood viscosity at corrected hematocrit (45%), erythrocyte aggregation index, erythrocyte rigidity index and hematocrit. Compared to curcumin at the same dose, Zn(II)–curcumin more effectively elevated SOD activity, ameliorated liver injury and improved hemorheological variables. These results suggest that Zn(II)–curcumin protected the rats from ethanol-induced liver injury and hemorheological abnormalities via the synergistic effect of curcumin and zinc.
