However, because of the variable prevalence of cell types, the distribution of labels was not homogeneous, and 4 (dacrocytes, elliptocytes, acanthocytes, and stomatocytes) of the 10 classes had <150 cells in their training set.
Approximately 50% acanthocytes were observed in the peripheral smear (Figure-1, diluted with saline).
Acanthocytes present, abundant on rhizomorphs and scattered in the hymenium and stem.
rugosoannulata is related to nematophagous fungi found in woods, grasslands and composts (Luo et al., 2006) which produce specialized structure of large spike cell called acanthocytes (Farr, 1980), which mechanically destroy nematodes eggs as well as J2.
rugosoannulata spores can be seen in Figure 1, showing that the acanthocytes sheared the nematodes while they were moving.
The hematuria is considered glomerular in origin when [greater than or equal to] 40 percent of at least 100 urinary RBC are dysmorphic, or [greater than or equal to] 5 percent are proven to be acanthocytes via phase contrast microscopy.
Blood film did not show any acanthocytes. Blood glucose concentration was 503 mg% with HbA1C of 9.3%.
Other clinical manifestations are serum [alpha]-tocopherol concentrations below or at the lower limit of the reference interval and abnormal erythrocyte morphology with characteristic acanthocytes, as seen in persons with vitamin E deficiency (4).
Acanthocytes are found more frequently in peripheral smears from patients with AD; in some individuals, this increase was noted a decade before the onset of dementia.[28] Walter and Widen[24] have demonstrated that electrophoretic mobility of red blood cells from patients with AD differs from healthy controls and that this difference depends on the anticoagulant used, appearing in citrate and oxalate but not in EDTA or heparin.
In the interest of simplifying reports and eliminating redundant information given to clinicians, some laboratories have moved to eliminating the non-specific term poikilocytosis and reporting only the specific type of abnormal RBC forms, (2) such as spherocytes, acanthocytes, and teardrops.
However, this system relies on erythrocyte volume and size, and the flow cytometer distinguishes erythrocytes on the basis of cellular diameter but cannot recognize dysmorphic erythrocytes with altered shape, such as acanthocytes or codocytes (8).
Use as concise description when Howell-Jolly bodies are present, accompanied by small numbers (e.g., [less than]5%-10%) target cells, acanthocytes, spherocytes, and Pappenheimer bodies.
