The Effect of Host and Cell Age on the Rat and Human Erythrocyte: Cellular and Immunologic Aspects,apacity after the reticulocyte stage. As such, the erythrocyte has been studied as a model for cellular aging in young hosts. The erythrocyte provides an equally fascinating model for the study of the effects of host age on cellular aging.

Hemostasis, Microcirculation, and Thrombophilia in the Aged,the other biochemical and functional modifications due to aging. While discussing hemostasis, microcirculation should also be considered, insofar as its alterations during aging may significantly affect the mechanisms of hemostasis as well as those of thrombophilia, according to the old theory of Virchow.

Influence of Age, Sex, and Blood Group on Blood Coagulation,h may yield diagnostic tools for the identification of risk factors, which hopefully could provide a basis for prophylactic or therapeutic medical programs, leading to lowered morbidity/mortality in large patient groups.

EXULT

Stefania Saviolo,Antonio MarazzaIt has been appreciated for some time that the immune response to foreign antigens is usually lower in old than in young humans. The greatest age-associated changes occur in immune reactions that depend upon thymic function. Thus, T cell-dependent immunity is more markedly compromised in the elderly than T cell-independent immunity.

The Cellular Basis and Clinical Significance of Immune Senescence,It has been appreciated for some time that the immune response to foreign antigens is usually lower in old than in young humans. The greatest age-associated changes occur in immune reactions that depend upon thymic function.

Conclusion and Future Directions,ütter et al. 1968; Mende 1965; Prankered 1958). The life span of erythrocytes demonstrates species-specific differences: in man it is 120 days and in mouse 50 days, while the red cells of the turtle have an especially high life span of about 500 days.
