[Prostaglandins. Their biological effects and technics for their measurement]. / Le prostaglandine. Effetti biologici e tecniche di misurazione.

A careful survey of known biological effects of various prostaglandins and measurement techniques is made. Limitations and advantages of these techniques are also indicated.

[Rarefying osteopathy in rheumatology. Methods of evaluation and comparison of urinary hydroxyproline and serum proline iminopeptidase]. / Le osteopatie rarefacenti in reumatologia. Metodi di valutazione e confronto tra idrossiprolina urinaria eprolinoiminopeptidasi serica.

Serum proline iminopeptidase and (where possible) urinary hydroxyproline were determined in 214 subjects: normal subjects, subjects with chronic kidney disease, subjects with chronic liver disease, subjects with osteitis deformans, subjects with rheumatoid arthritis, and subjects with osteoporosis. The values of the two parameters fully corresponded. It is suggested, therefore, that proline iminopeptidase can be determined instead of hydroxyproline in cases where a primarily destructive bone disease in present.
