Objective symmetry detector method for gammaencephalography. I. Physical characteristics.

A symmetry detector method for gammanecephalography is described. It is based on two detectors, collimated by square tubes with large apertures. Increase ratios and side difference ratios should be used as evaluation parameters in clinical applications and are therefore analysed theoretically and experimentally from measurements on a phantom system. The effect of energy discrimination is analyzed and found to be small over a wide range of the lower discrimination level setting. The chosen performance of the measuring routine used made errors caused by the electronic devices negligible in relation to the loss of precision occurring from counting statistics.

Objective symmetry detector method for gammaencephalography. II. Normal range.

A standardized clinical examination procedure of a previously described symmetry detector method for gammaencephalography is presented and the results obtained from a reference group of subjects without known neurologic disorders are reported. The 99TcmO4 distribution in the skull was investigated by 208 evaluation parameters obtained from measurements of 24 subregions of the skull from 48 symmetrical positions. Mean values and associated inter-individual and intra-individual standard deviations are given. Different sources of variation are discussed in relation to the results obtained. The method enables the 99TcmO4 distribution in the skull to be objectively classified as normal or abnormal.

Objective symmetry detector method for gammaencephalography. III. Diagnosis of abnormal 99TcmO4 distribution in the skull.

The objective classification of results of the previously described symmetry detector method for gamma encephalography is reported. The different evaluation parameters were chosen after comparing their detectability in different subregions of the head or as a result of findings in certain patients. The detectability was estimated from the results of phantom measurements related to the normal ranges of evaluation parameters. The borders of the classification criterion are discussed in relation to the number of evaluation parameters used.

Physical mapping of the Schizosaccharomyces pombe histone genes.

The histone-encoding genes in Schizosaccharomyces pombe were physically mapped by hybridisation to filters containing cosmid and P1 genomic libraries. The H2A.2 gene and the H2A.1-H2B.1 gene pair mapped between the ade6 and rikI genes on chromosome III. The three H4-H3 gene pairs were mapped to three different regions by a H4.1 probe. Southern analysis of clones from each region revealed the positions of the three H4-H3 gene pairs. H4.1-H3.1 was localised to chromosome I between the mei2 and rad1 genes; H4.2-H3.2 mapped between rad3 and cdc2 on chromosome II; H4.3-H3.3 was localised to a region between the nuc1 and puc1 genes on chromosome II.
