    Notes: Abstract During the years 1979–1988, 63 children (38 male: 25 female) were first diagnosed as having Crohn's disease on the basis of histological findings. Twenty-nine per cent were less than 10 years old at the onset of symptoms; 40% of these cases took more than 1 year to diagnose. Most patients (59%) presented with abdominal pain and diarrhoea, but 40% presented with: a non-specific illness (14%); upper gastro-intestinal tract symptoms (14%); growth failure (6%); systemic disease (5%), or peri-anal disease (1%). There were signs of abdominal tenderness, distension, or an abdominal mass in over 50% of cases. Peri-anal Crohn's disease was present in 41% and a height less than the 10th centile was recorded at diagnosis in 45%. Children were treated with a combination of prednisolone and sulphasalazine. In 16 cases a bowel resection was performed. Surgery was indicated for localised stricture formation causing obstruction and for persistence of severe disease poorly responsive to steroids, particularly in the prepubertal child with growth failure. The extent and distribution of disease influenced outcome. Twenty-four of 39 children followed for more than 3 years are either well-controlled or disease-free at present.

    Notes: Abstract The site, depth and duration of burial significantly influenced the viability and state of dormancy of Solanum mauritianum seeds. Burial at a depth of 15 cm was most effective in reducing the level of conditional dormancy. Secondary dormancy was not induced at any of the environmental (burial) sites when seeds were maintained at 15 cm, where light and temperature fluctuations were minimal. When buried at 4 cm or maintained on the soil surface secondary dormancy was induced, particularly at the inland sites where environmental conditions such as temperature and moisture were more extreme. Conditional dormancy could generally be overcome by incubating seeds at 15/30 °C in the light, even after prolonged burial at unfavourable germination conditions. Gibberellic acid (500 mg l−1) was very effective in breaking secondary dormancy of seeds induced by storage under unfavourable conditions after burial. These results have important implications for the control of this week in commercial forests.
