Psychoacoustical performance in children.

In order to contribute to knowledge of the elementary auditory functions in infancy, a group of normally hearing children below the age of four years was examined using advanced tests for cochlear (remote masking, brief-tone audiometry, critical ratio) and central auditory functions (masking-level difference). The results showed that both cochlear and central auditory functions were almost the same in three-year-olds as they were in adults, if not better. This behavior is similar to that recorded with electrophysiological methods and leads to the conclusion that at age three years the auditory system has completed its neurofunctional maturation and it is therefore completely efficient in its elementary psychosensorial functions.

The use of collagenase-clostridiopeptidase combined with chloramphenicol in orthopaedics and traumatology.

The authors report a consecutive group of 95 patients suffering from chronic ulceration treated by a mixture of Collagenase Clostridiopeptidase A and 1% Chloramphenicol. Some cases involved skin only, some affected skin and muscle, and some also affected bone. The treatment was successful in all cases. The mixture acts by inducing debridement and cleansing of the necrotic areas and stimulating granulation tissue formation. This is followed by epithelialisation. At the same time the vitality of the deep tissues is maintained, even when it involves bone.

Regulation by the cAMP cascade of oxygen free radical balance in mammalian cells.

A study is presented of the effect of the cAMP cascade on oxygen metabolism in mammalian cell cultures. Serum-starvation of the cell cultures resulted in depression of the forward NADH-ubiquinone oxidoreductase activity of complex I, decreased content of glutathione, and enhancement of the cellular level of H2O2. Depressed transcription of cytosolic Cu/Zn-SOD 1, mitochondrial glutathione peroxidase and catalase was also observed. Activation of the cAMP cascade reversed the depression of the activity of complex I and the accumulation of H2O2. The effect of cAMP involved the cAMP-dependent protein kinase.
