[Clinico-experimental research on the use of collagen in periodontal disease].

Clinico-experimental studies of a new collagen derivative are presented. Experimental investigation in 30 rats showed the substance to promote wound healing. It also proved efficient in the five-years clinical follow-up of 254 patients after 441 surgical interventions (generalized periodontitis).

[Composition of biliary calculi and possible causes of their formation].

The ingredients and chemical content of 135 biliary calculi from 120 operated patients was studied roentgenostructurally, with infra-red spectrophotometry and visually. Based on the results obtained, it proved feasible to differentiate 4 groups of calculi differing in their content: cholesterol, metallocholesterol, cholesterolphosphatide, phosphatide-protein.
