A study of the frequency of hepatocellular mitotic figures in human autopsy cases.
Five autopsy cases showing more than 20 hepatocellular mitotic figures per 1 cm2 of liver parenchyma had also widespread skeletal muscle necrosis and renal failure. Myoglobin casts in renal tubules were remarkable. In three of these cases liver cell damage was obvious, but in two others it was negli gible. Mechanisms of muscle necrosis were probably different from case to case. For a control st...
متن کاملScanning electron microscopic study of the mitotic figures in cultivated cells.
Two cell lines established from human stomach cancers were used in this experiment. After culture by the coverslip method, cells were fixed and coated with carbon and gold to be observed under the scanning electron microscope. 1. When the cells began to grow in a monolayer after the subculture, the boundaries between interphasic cells were indistinguishable. The nuclei in the interphasic cells ...
متن کاملDoes delay in fixation affect the number of mitotic figures in processed tissue?
The effect of delay in fixation on the number of mitotic figures in tissues has received little attention, and previous studies have reached differing conclusions. The numbers of mitotic figures in the normal mucosa of six colectomy specimens were counted with delays in fixation of 30 minutes, one hour, two hours, three hours and six hours for samples from each specimen. The numbers of mitotic ...
متن کاملComparison and evaluation of mitotic figures in oral epithelial dysplasia using crystal violet and Feulgen stain.
BACKGROUND Routine staining procedures often pose a problem in differentiating a mitotic cell from an apoptotic cell, deteriorating the reliability of histology grading. Although various new methods have been recommended for identifying mitotic figures (MFs) in tissues, the time factor and cost makes them less feasible. Thus, an attempt was made to evaluate the efficacy of crystal violet and Fe...
متن کاملDetermining Image Processing Features Describing the Appearance of Challenging Mitotic Figures and Miscounted Nonmitotic Objects
CONTEXT Previous studies showed that the agreement among pathologists in recognition of mitoses in breast slides is fairly modest. AIMS Determining the significantly different quantitative features among easily identifiable mitoses, challenging mitoses, and miscounted nonmitoses within breast slides and identifying which color spaces capture the difference among groups better than others. M...
