Quantitation of histochemical staining of salivary gland mucin using image analysis in cats and dogs. 1999

Two different, computer-based, image analysis methods were employed to complement subjective assessment of patterns of mucin staining (by periodic acid Schiff/alcian blue, aldehyde fuchsin/alcian blue and potassium hydroxide-alcian blue/phenylhydrazine hydrocholoride) in digitised images of sections of major and minor salivary glands from cats and dogs. Image analysis based on red, green and blue (RGB) staining was not suitable for quantitation of histochemical staining of mucin in salivary glands. Image analysis based on hue, saturation and lightness (HSL) allowed quantitative assessment of staining by different stain components and of mixed staining, and enabled comparison of staining of different glands in dogs and cats. Quantitative analysis based on HSL allowed differentiation of differences in staining patterns of major and minor cat and dog salivary glands, and between the species; such differences would have been impossible to distinguish on subjective grounds alone. Quantitative assessment of normal salivary gland histochemistry allows comparison with staining patterns in disease.

D002415 Cats The domestic cat, Felis catus, of the carnivore family FELIDAE, comprising over 30 different breeds. The domestic cat is descended primarily from the wild cat of Africa and extreme southwestern Asia. Though probably present in towns in Palestine as long ago as 7000 years, actual domestication occurred in Egypt about 4000 years ago.
