Theex situ conservation of temperate rainforest conifer tree species: A British-based programme
This programme provides a practical initiative promoting the conservation of rare and endangered conifer and associated temperate rainforest tree species, by providing a scientifically sound strategy to minimise further genetic erosion of an already fragmented wild tree resource. Using existing horticultural expertise and the tree-growing potential of the British climate, the programme provides for the development of permanent, scientifically structured, threatened conifer breeding populations, in a network of sites across the British Isles and elsewhere, as a long-term species rescue strategy. To these sites are attached important future research and public education programmes.
Endomycorrhizae in glasshouse grown conifers
Summary The identity of a fairy-club fungus commonly associated with glasshouse grown conifers belonging to families other than the Pinaceae was confirmed as Clavaria acuta. In studying the relationship between this fungus and plants with which it grows, endogonaceous fungi were found to be associated with root nodules formed on conifers over a wider range than previously reported.
Accumulation of Bone-Seeking Radionuclides in Liver Metastasis from Colon Carcinoma
Fifteen colon cancer patients with metastasis to the liver were examined by both liver and bone scans. Seven of these showed accumulation of bone seeking radionuclides in the liver at the site of a defect in the scan. Such accumulation was found in two diphosphonate, in one pyrophosphate and in six 18F scans. To our knowledge, this is the first series to report localization of 18F in intrahepatic metastasis from colon cancer. The precise mechanism for this non-skeletal accumulation is unknown.
