BUT: The aim of the present study was to establish the influence of the moderate combined oral contraceptives on the concentration of the individual proteins in serum.
Material and methods: The study included 70 women at the age from 16 to 30, separated into two groups: control group, including 30 women who have not used OC basic group, including 40 women using Cilest and Marvelon in the period of one to three years. There have been examined the following individual proteins in serum: prealbumin; orosomucoid; haptoglobin; TRA; C3; C4; CRP; IgA; IgG and IgM. Their level in serum was defined with immunoturbidimetric method with monoclonal antibodies of the firm Kone (Fin).
Results: The data showed reduced concentrations of Orosomucoid and increased concentrations of TRA in the basic group.
Conclusions: The continuous use of Cilest and Marvelon do not influence the concentrations of the examined individual proteins in the serum. They lead to reduced concentrations of orosomucoid and increased concentrations of TRA.
