With the increasing interest in the diagnosis of malignant cells in various exudates and body fluids, a method demonstrating certain nucleolar changes in considerable detail may be of value. I t is t he purpose of this paper to present such a method and to discuss briefly the nucleolar changes in benign and malignant tissues and also to point out the potential applicability of this method as an...

The vitamin A uptake cells in the anterior pituitary, thyroid gland, and pancreas of Japanese quails, coturnix coturnix japonica, were examined by the use of Sudan III staining, toluidine blue staining, fluorescence microscopy and electron microscopy. After excess vitamin A administration, most of interstitial cells, corresponding to fibroblasts, increased markedly the size and number of lipid ...

UNLABELLED PREMISE OF THE STUDY Here we propose a staining protocol using toluidine blue (TBO) and ruthenium red to reliably identify secondary compounds in the leaves of some species of Myrtaceae. • METHODS AND RESULTS Leaves of 10 species representing 10 different genera of Myrtaceae were processed and stained using five different combinations of ruthenium red and TBO. Optimal staining c...

Histochemical methods based on either well-established Toluidine Blue staining or contemporary immunohistochemical labeling based on myosin and laminin antibodies were applied on comminuted chicken meat to evaluate the potential of different histological methods to objectively detect muscle tissue and muscle tissue degradation. Also, Haematoxylin-Eosin staining was studied for the same purposes...

The aim of the present study was to evaluate effect different staining techniques on applicability and accuracy tooth cementum annulation (TCA) method. Nine decalcination techniques, 8 dehydration protocols were applied in 3 teeth from persons a known age. Black white, color images histological sections captured. An x- ray taken each they photographed. Researchers asked observe both black/white...
