The purpose of this work was to determine the protein composition of whole saliva in 50 year-old patients an d older with manifested and terminal stages of periodontal disease, in correlation with control group of young healthy persons. Experimental and control group consisted of 30 patients. The periodontal status was determinate by using appropriate periodontal index (Sillness-Loe). Investigations were led by electrophoretic method on aragose gel which was used as a routine method for investigation of human serum proteins. Investigating in very alkaline conditions (pH-H) as well as acid conditions (pH=5.9) resulted in separating alkaline and acid glycoprotein fractions in whole saliva. Results showed that there were more separated fractions within basic conditions than within acid conditions. The fraction identification was done by using relative molecule mass determination method by Weber and Osborne. Molecule mass fractions at basic conditions in comparison with the healthy sample (Sz) indicated the destruction of big molecular weight alkaline proteins as well as a significant presence of acid fractions, of little molecule masses up to 60 000 (St), consequences due to aging processes in human organism. It can be concluded that changes in protein composition of whole saliva could point out to the direction and development of periodontal disease as well as changes concerning aging of human organism. |
