[Pre-prosthetic plastics of labial vestibule in patients with toothless lower jaws].

The acquired practical experience in the treatment of 20 in-patients is shared. All of them had advanced and severe atrophy of alveolar process and the body of mandibule. Two methods of vestibuloplastics were mainly applied: according to K. Schuchardt and the method of H. Pichler. The very good early and late results attained as regards the prosthetic field enabled the accomplishment of functionally fit prosthetic construction.

[Effect of pH on tryptophan fluorescence of phosphorylase kinase].

The influence of pH on tryptophane residues in phosphorylase kinase was determined by iodide quenching of tryptophan fluorescence. The experiments were carried out in the pH range of 6 to 10 and the results were presented in a modified Stern--Volmer plot. It was found that the fraction accessible to the quencher was smaller at pH 6 and increased at basic pH of the solution. The results correlated with the enzymatic activity and were interpreted as a structural change in the enzyme molecule. The polarized fluorescence measurements indicated that some aggregate processes proceeded together with the decrease of pH under 7.
