COMPARISON AMONG HUMAN-BLOOD LIQUID SOLUTIONS

In this paper the authors intend to illustrate the results of optical properties of human blood as suspension of cells in aqueous solutions of electrolytes and non-electrolytes, which are highly complex liquid systems susceptible to important phase transitions. They carried out n ormal and derivative spectrophotometric measurements of non-pathologic diluted blood and serum samples to show optical absorption peak posit ions of haematological chromophores including haemoglobin and fibrinog en. The authors think that optical behaviour of the chromophores may b e influenced by interaction with different environmental situations re lative to coagulated and uncoagulated samples. They continue these stu dies with particular reference to the nature of the solute-induced mod ifications.
