    Notes: Preliminary experiments were conducted to assess the winter hardiness of representative cultivars or populations of Festuca rubra, Holcus lanatus and Agrostis spp. in comparison with a hardy (Premo) and a susceptible (Grasslands Ruanui) cultivar of Lolium perenne. Two controlled-environment tests and a field experiment including two cutting and two fertilizer managements are reported.Grasslands Ruanui andH lanatus suffered most damage in all tests. In the controlled-environment experiments, Premo was at least as hardy as the F. rubra and Agrostis cultivars but in the field Premo was more susceptible. Spring growth of Premo was affected more by the cutting and fertilizer managements applied the previous summer and autumn than was spring growth of F. rubra or Agrostis spp.It was concluded that, whereas use off. F. rubra or Agrostis spp. should not be limited by fears of winter damage, poor winter hardiness may limit the value of H. lanatus for hill and upland reseeding.

    Notes: Nitrous oxide concentrations (V/V) at the delivery Rotameters block, nasal mask, pharynx and venous blood, were compared. There was a dilution of approximately 50% of the delivered nitrous oxide at the nasal mask which was further reduced in the pharynx. Venous blood concentrations 10 minutes after inhalation of nitrous oxide were low but as would be calculated from pharyngeal concentrations. After 5 minutes of oxygenation venous blood nitrous oxide concentrations were still relatively high. A total of 92% of subjects experienced a satisfactory effect with 30% nitrous oxide or less in the pharynx.

    Notes: Maternal factors are known to influence the heritability and expression of asthma and atopy. We report the association of maternal, paternal and proband GSTP1 genotype with lung function in 145 Caucasian children with asthma. GSTP1 Val105/Val105 and Ala114/Val114 genotypes in the child were associated with non-significant increases in lung function (forced expiratory volume in 1 second (FEV1), forced vital capacity (FVC) and the FEV1/FVC ratio). Paternal genotype had no influence on lung function in the child. In contrast, maternal GSTP1 Val105/Val105 genotype was significantly associated with offspring lung function and was strongly predictive of FEV1/FVC (Val105/Val105 105.2%, Ile105/Val105 and Ile105/Ile105 97.9% p = 0.006) and maternal GSTP1 Ala114/Val114 genotype was associated with significantly higher FEV1 (Ala114/Val114 109.0%, Ala114/Ala114 99.0% p = 0.008), and FEV1/FVC ratios (Ala114/Val114 104.1%, Ala114/Ala114 98.2% p = 0.04). The associations between maternal GSTP1 Val105/Val105 genotype and FEV1/FVC and maternal GSTP1 Ala114/Val114 genotype and FEV1 remained significant (p = 0.003 and p = 0.007) after correction for child and maternal atopic status, passive smoke exposure, smoking during pregnancy, individual and paternal GSTP1 genotype and was independent of transmission to the child. These data support the hypothesis that maternal GSTP1 genotype can act as a specific risk factor which has ex utero consequences for children with asthma. As a child's genotype is not independent of maternal genotype, effects seen in candidate gene studies may be due at least in part to this phenomenon.

    Notes: Rationale Previous data have suggested that glutathione-S-transferase (GST) genotypes are important in determining the rate of lung function growth in childhood. This effect was most marked in Caucasian children with asthma.Objectives We investigated the association of lung function with GSTM1, GSTP1 and GSTT1 genotypes in Caucasian families with asthma.Methods Four hundred and eighteen children and 316 parents from 224 Caucasian families were recruited via a child with asthma, the proband. Associations between lung function and GST genotype were determined using multilevel models.Results There were no observed associations between lung function and GST genotype in parents. However, in the children, the GSTP1 val105/val105 and GSTM1 null genotypes were associated with significantly higher forced expiratory volume in 1 s (FEV1) and FVC values as percentage of predicted. This effect was not statistically significant in the probands but was marked in their siblings in whom GSTP1 val105/val105 was associated with 9.4% higher FEV1 and 10.7% higher FVC (P=0.005 and 0.001, respectively). The GSTM1 null genotype was associated with a 6.7% higher FEV1 and 4.1% higher FVC (P=0.003 and 0.063, respectively). These effects remained significant after correcting for the confounders of individual atopic status, tobacco smoke exposure and familial aggregation of lung function values.Conclusions GSTM1 and GSTP1 genotypes are important determinants of lung function in childhood. The smaller differences seen in probands are predicted by a simple model in which more rapid decline in lung function is seen in these individuals.

    Notes: Abstract Dental caries, debris (DI-S) and sugar intake were determined for 766 rural Black, urban Black, coloured, Indian and While children, using standardized techniques. In general sucrose intake, both quantity and frequency was low in rural Black children yet these children had relatively few caries-free individuals and higher than expected mean dmft scores. Comparison with earlier studies in the same localities has shown a worsening of dental caries in all groups except the White, in which the situation has improved. Sucrose consumption declined in rural Black, and White groups, remained steady in urban Black children and increased in coloured and Indian groups.

    Notes: The pulpal response to Protemp® (ESPE Gmbh) was compared to zinc oxide-eugenol, Super Syntrex (de Trey) and Protemp® plus zinc oxide-eugenol liner in 144 vervet monkey (Cercopilhecus pygerythus) incisor teeth, according to ADA Specification No. 41. Cellular displacement into dentinal tubules, superficial and deep inflammation were present only in the 3-day specimens in all materials. Mean scores for the test material were lower than both negative and positive controls. In the 30-day specimens the prevalence of reparative dentine under the test material was similar to the negative control, while at 90 days it was less than (he negative control, although the severity in affected specimens was more than the positive control. Use of a zinc oxide-eugcnol liner reduced the severity of reparative dentine formation.

    Notes: During surveys of sugarcane fields in western and central Cuba from December 2001 to March 2003, the delphacid planthopper Saccharosydne saccharivora was the most prevalent of the Auchenorrhyncha fauna surveyed. Individuals of S. saccharivora collected tested positive for the sugarcane yellow leaf phytoplasma (SCYLP). Saccharosydne saccharivora were reared in cages and used for experimental transmission studies of SCYLP. The S. saccharivora were given acquisition-access feeds of 72 h on SCYLP-infected canes collected from the field followed by an inoculation-access period of 15 days on healthy sugarcane seedlings. Symptoms of yellow leaf syndrome developed on 24 out of 36 plants, 7–12 months postinoculation. None of the 36 healthy seedlings that were inoculated with S. saccharivora fed on phytoplasma-free sugarcane developed symptoms. All phytoplasma-positive sugarcane and S. saccharivora samples showed identical RFLP patterns and had 99·89% similarity in their 16S/23S spacer-region sequences, but only 92·6–93·6% similarity with other phytoplasmas. Sequences were deposited with GenBank [accession numbers: 〈accessionId ref="info:ddbj-embl-genbank/AY725237"〉AY725237 (S. saccharivora) and 〈accessionId ref="info:ddbj-embl-genbank/AY257548"〉AY257548 (sugarcane)]. Phylogenetic analysis suggested that the phytoplasmas from sugarcane and S. saccharivora are putative members of a new 16Sr phytoplasma group. This is the first report of vector transmission of a phytoplasma associated with sugarcane yellow leaf syndrome and the first time that S. saccharivora has been shown to vector a phytoplasma.
