Self-protection, blood

Self-protection. To prevent blood loss when a vessel is injured, the blood has systems for stanching blood flow and coagulating the blood (hemostasis see p. 290). The dissolution of blood clots (fibrinolysis) is also managed by the blood itself (see p. 292). 

The human body contains a number of self-protection barriers, such as blood and tissue microbicidal agents, including complement, lysozyme, beta-lysins, and iron-binding host proteins [6]. However, because this is not the focus of this book, we will look at other aspects of interest in the topical anti-infective arena. 

Blood is a distinct liquid tissue of higher animals, ensuring the transfer of nutrients and metabolic products, gas exchange, metabolic and heat balance. It is also important in the defence reactions of the organism used in self-protection, such as immunological response and coagulation involved in clotting. Blood represents about 5%... 

In the 2002 OHTS predictive study, diabetes appeared to be protective against the development of primary open-angle glaucoma. However, diabetes mellitus was entirely self-reported and not confirmed by chart review or blood tests. Thus, these data are probably incomplete and incorrect. Subsequent extensive statistical analyses in 2007 revealed that the association of diabetes with development of primary open-angle glaucoma could not be estimated reliably in the OHTS.
