[Protein synthesis in vivo in muscles of the growing lamb].

The relationship between incorporation of intravenously injected 14C lysine and specific radio-activity of precursor was used to estimate protein synthesis in muscle of growing lambs. The rate of protein synthesis per unit of muscle weight in Supraspinatus and Extensor digitorum longus decreased strongly from one week of age to puberty (10 weeks); afterwards it decreased in supraspinatus and increased slightly in Extensor digitorum longus. The rate of protein synthesis increase in muscle protein weight was constant during the whole experiment (1 week-16 weeks). In preruminant Lambs )1 week-5 weeks) the rate of protein synthesis per unit of muscle weight decreased; however, due to the increase in muscle weight, the rate of protein synthesis in whole muscle remained relatively constant. In order Lambs the rate of protein synthesis in whole muscle decreased. The turnover time of protein increased with age. These results give some explanation on muscular development of Lambs.

Monoamine acid metabolites in ventricular CSF of patients with brain tumours.

Homovanillic acid (HVA) and 5-hydroxyindolacetic acid (5-HIAA) in ventricular CSF were determined in 19 patients (12 female 7 male) with brain tumours. No relationship was found between ventricular fluid pressure (VFP) and levels of HVA and 5-HIAA. A relationship was observed between ventricular CSF, HVA concentrations and tumour induced alterations in CSF dynamics. HVA concentrations were very high in patients whose tumours involved the third ventricle, the aqueduct, or the fourth ventricle, producing marked alterations in CSF flow. HVA concentrations significantly lower than in controls were observed in cases where tumours involved the lateral ventricles. Concentrations of acid metabolites in patients with little or no alteration in CSF dynamics corresponded with those in patients with other neurosurgical disorders.
