The present study was designed to investigate the effect of temporary examination stress on some biochemical parameters in sera of fifty five apparently healthy undergraduate students with age range (19- 24) years and (23.9 ± 2.13 kg/m2) body mass index, they were from University of Baghdad, College of Science; specialty from Mathematic, Physics, Geology, Biotechnology Departments, and also from Al-Esraa College, Medical Analysis Department.
To compare the results, blood samples were obtained from the undergraduate students in two days, the first day was a normal day (Nday) and the second day was after 7-15 days, in the morning before the written exam (Eday). Based on gender, blood types, Rh blood type, exam performance, and the first semester score, the students were classified into several subgroups.

Excerpt from the Thesis
1.2.6.2: Physiological Functions of Ceruloplasmin
Ceruloplasmin, the multifunctional copper containing enzyme, possesses significant functions as following; ferroxidase activity, oxidase activity, transport of copper, serum antioxidant, and endogenous modulator of the inflammatory response.
Cp has been implicated in iron metabolism mostly because of its catalytic oxidation of Fe (II) to Fe (III) by its ferroxidase activity (Bento et. al., 2007). With its subsequent incorporation into apotransferrin (Osaki et. al., 1969;1966) or into the Fe storage protein ferritin (Van Eden & Aust, 2000). The copper in Cp plays an important role in the oxidation of iron before it is transported to the plasma (Yuan et. al., 1995; and Osaki et. al., 1966).
Cp also catalyzes the reduction of an oxygen molecule with formation of water, without releasing intermediaries potentially toxic (O2-, H2O2) (Osaki S., et. al., 1969). Cp possesses a significant oxidase activity directed toward substrates such as aromatic amines, phenols and ascorbate (Holmberg & Laurel, 1951). It acts as a regulator of plasma and tissues biogenic amines levels, this function of Ceruloplasmin is used for it's in vitro assay and identification (Osaki et. al., 1964). The following equations can explain the oxidation reaction catalyzed by Cu-Cp and free Cu:
