A research is conducted on the relationship between the normal reference value of 20,475examples of hemoglobin of young women and five geographical factors in 208 areas in China, thenormal reference value is determined by the hemoglobincyanide method. It is found that thecorrelation of geographical factors and the normal reference value of hemoglobin of young womenare quite significant (F=142.81). By using the method of multiple linear regression analysis, oneregression equation is inferred. If geographical values are obtained in some areas, the normalreference value of hemoglobin of young women of this area can be reckoned by using the regressionequation. Furthermore, depending on the geographical factors, China can be divided into six regions:Qinghai-Tibet (Qingzang) Plateau, Southwest, Northwest, Southeast, North and Northeast China.

Intrinsic fluorescence emission maxima of hemo-lobin(Hb) was investigated in relation to peroxidase property of Hb. The peroxidase activity of Hb was based on its catalytic activity for oxidation of o-phenylenediamine by hydrogen peroxide. Hb was treated in the condition (temperature,ethanol and salt) that tetramer-dimer equilibrium of Hb is shifted to the dimer state and its fluorescence spectrum was measured. When Hb treated in temperature (60-70 ℃), ethanol concentration (60%-70%) and NaCl concentration (2. 5-3.0 mol/L), the fluorescence emission maxima of Hb shifted towards red wavelength and its activity decreased quickly.Experimental results revealed that the activity and stability of Hb as mimetic peroxidase was closely relative to the hydrophobic environment of active center of Hb, and when Hb (FeⅡ) converted into met Hb (FeⅢ ), its activity was 1. 6 times as much as that of Hb.
