| 1 | The Application of the Edge Sharpening Operator to the Breast Near-Infrared Imaging显示文摘The principles of Gradient operator, Laplacian operator, LOG operator and Sobel operator are discussed. Certain features of breast can be extracted in different degrees and aspects from original images by applying four edge sharpening operators to the breast near infrared imaging. A great number of cases prove that compared with the other three operators, the improved Sobel operator can effectively extract the structural features of the breast from an original image. It can be concluded that the improved Sobel operator can assist in diagnosing breast diseases. | Xiang Yan 1 , Li Kai yang 1 , Yang Xuan dong 1 , Wang Xiao fang 2 ,Zhang Xian lin 2 ,Zhu Yi jun 3 1.

| 10 | Chromosomal localization of ribosomal DNA sequences in an apple rootstock using a digoxygenin detection system显示文摘A 6kb rDNA probe comprising the 18S coding plusspacer sequences has been hybridized to the metaphase chromosomes of apple rootstock cultivar MM106 demon-strating the localization of ribosomal gene arrays in the vicinity of the telomeric regions of the short arms of chro-mosomes 6 and 14. The in situ results using digoxygenin labelling coupled to an alkaline phosphatase immunoassay were confirmed by silver staining for NORs and nucleoli. This study demonstrates the feasibility of molecular cyto-genetic analysis of very small chromosomes (1.0-2.7μm)of apple. | ZHU JIMEI S E GARDINER (The Horticulture and Food Research Institute of New Zealand Limited) (Mt Albert Research Centre, Privatc Bag 92 169, Auck-land, New Zealand)(Batchelar Research Centre, Private Bag 11 030,Palmerston North, New Zealand) | 1995 | Cell Research1995，5，1： | 0 |
