    Notes: Tannin content and tanning power on haemoglobin were evaluated in a collection of faba-bean genotypes differing in seed and flower colour. All tannin-related measurements gave near-zero values for white-flowered genotypes; they showed intermediate values in brown and green-seeded genotypes, brown being lower in tannin values than green. Genetic analysis in the F3 of a half-diallel design confirmed the strong link between brown and green testa colour and intermediate tanning activities.

    Notes: A new spontaneous mutation is described in faba bean, Vicia faba L., characterized by a marked green colour in the entire cotyledon tissues of the mature seeds, while the wild phenotype is yellow. This seed character reflects the embryonic genotype and is determined by a single recessive allele named i1-1. It is distinct from the y gene, which codes for green testa. As is the case for gene y, the gene i1-1 displays no epistatic effects with the zero-tannin genes zt1 and zt2 which influence seed and flower colour in faba bean. In this allogamous species, such a mutation is a useful tool in cross-fertilization studies.

    Notes: Abstract. The purpose of this work was to demonstrate the feasibility of a new imaging technique called synchrotron radiation computed tomography (SRCT). This technique leads to a direct assessment of the in vivo concentration of an iodine- or gadolinium-labeled compound. Rats bearing C6 glioma were imaged by MRI prior to the SRCT experiment. The SRCT experiments were performed after a 1.3 g I/kg (n = 5) or a 0.4 g Gd/kg (n = 5) injection. Finally, brains were sampled for histology. The SRCT images exhibited contrast enhancement at the tumor location. Ten minutes after injection, iodine and gadolinium tissular concentrations were equal to 0.80 ( ± 0.40) mg/cm3 and 0.50 ( ± 0.10) mg/cm3, respectively in the peripheral area of the tumor (respective background value: 0.20 ± 0.02 to 0.10 ± 0.01). Correlation to MRI and histology revealed that the contrast uptake occurred in the most vascularized area of the tumor. The present study summarizes the feasibility of in vivo SRCT to obtain quantitative information about iodine and gadolinium-labeled compounds. Beyond brain tumor pathology, the SRCT appears as a complementary approach to MRI and CT, for studying iodine- and gadolinium-labeled compounds by the direct achievement of the tissular concentration value in the tissue.

    Notes: Abstract Cerebral blood flow (CBF) studies have provided some insight into pathophysiological mechanisms of cerebral damage in newborn children; their value in predicting brain damage, however, remains elusive. The purpose of our study was to evaluate the role of CBF measurements in predicting developmental outcome in preterm neonates at 18 months. Preterm babies with a gestational age of less than 34 weeks and a birth weight of less than 1500 g (n = 71) were enrolled in the study. CBF was measured by the nonivasive intravenous 133Xe method on three different occasions. We classified our measurements into three groups: depending on the time when performed group 1: between 2 and 36 h (n = 52); group 2: between 36 and 108 h (n = 44); group 3: between 108 and 240 h (n = 41). At the age of 18 months neurodevelopment testing was performed according to the Bayley mental and motor scales. Surviving infants had a higher mean CBF over the three groups than non surviving children (15.2 ± 3.5 ml/100 g brain tissue/min vs 13.0 ± 2.1 ml/100 g brain tissue/min, P 〈 0.05). There was no correlation of CBF with mental or motor development in our study population in either of the three groups. Conclusion In preterm infants basal CBF is higher in surviving than in non surviving infants, but there is no correlation of resting CBF and later neurological outcome.
