Keratomileusis was investigated in five stumptail monkey eyes (Macaca speciosa). An arbitrary flattening of six diopters was selected and programmed in the computer for each eye. The actual ...flattening achieved two weeks after surgery ranged from -4.00 D to -6.00 diopters (D). One to 5 diopters of the initial effect was lost during the six-month observation period. Histopathology of two eyes demonstrated attenuation and/or loss of Bowman's membrane with overlying epithelial defects.
In two patients with chronic myeloid leukemia (CML), the nature of the chromosomal rearrangement giving rise to "masked" Ph has been studied by in situ hybridization of human c-abl sequences. The ...c-abl probes hybridized to the 22q11 region of the "masked" Ph, demonstrating that translocation of sequences from 9q34 to the Ph did occur exactly as in standard Ph or in other types of variants previously studied. These results provide additional evidence for the occurrence of a constant molecular rearrangement in Ph-positive CML.

Journal Article
Cytogenetic studies were performed in a case of progressively transformed germinal centers (PTGC), and in a case of nodular paragranuloma (NP; Hodgkin's disease with lymphocytic predominance, nodular ...type). No cytogenetic abnormalities were detected in PTGC. Chromosomal aberrations (hyperdiploidy, 6q-, +21, and several unidentified markers) were found in NP. The results support the proposal that PTGC are reactive in nature and NP is a neoplasm. Chromosomal analysis could provide practical diagnostic aids in the differential diagnosis of PTGC and NP.
