hyaline cast การใช้

• Their appearance is generally more cigar-shaped and of a higher refractive index than hyaline casts.
• In kidneys, the renal tubules have hyaline droplet deposition in the epithelia and hyaline casts in the lumen.
• The most common type of cast, hyaline cast are solidified Tamm Horsfall mucoprotein secreted from the tubular epithelial cells of individual nephrons.
• Formed by the breakdown of lipid-rich epithelial cells, these are hyaline casts with fat globule inclusions, yellowish-tan in color.
• While most often indicative of chronic renal disease, these casts, as with hyaline casts, can also be seen for a short time following strenuous exercise.
• Low urine flow, concentrated urine, or an acidic environment can contribute to the formation of hyaline casts, and, as such, they may be seen in normal individuals in dehydration or vigorous exercise.
• All rely on the inclusion or adhesion of various elements on a mucoprotein base the hyaline cast . " Cast " itself merely describes the shape, so an adjective is added to describe the composition of the cast.
• Hyaline casts are cylindrical and clear, with a low refractive index, so that they can easily be missed on cursory review under brightfield microscopy, or in an aged sample where dissolution has occurred whereas, on the other hand, phase contrast microscopy leads to easier identification.
