INTRODUCTION Until recently, histology and biochemistry have been two practically independent branches of biology. Histologists have prepared thin sections and stained them to elucidate details in the microscopical structure of the specimen. Biochemists, on the other hand, have mainly been interested in the chemical composition of gross anatomical samples of organisms. During the last few decad...

the histological analysis, disposition and histochemical localization of tryptophan were investigated in the pancreas to compare the cellular organization and histochemical characterization in the pancreas of labeo rohita (hamilton, 1822), mystus vittatus (bloch, 1790) and notopterus notopterus (pallas, 1769) having different feeding habits. histological analysis demonstrated that the exocrine ...

Extrafusab muscle fibers maintain uniform structural and histochemical characteristics over their entire length (4). This is unlike the behavior of intrafusal muscle fibers in mammalian muscle spindles that display regional structural and histochemical differences along the fiber length as shown by Banks et al. (1) and Kucera (8). In this study it has been noted that some intrafusal muscle fibe...

There is currently much speculation over the precise nature of lobular carcinoma in-situ of the breast and its significance. Histochemical study shows that it is rich in sialomucin. This has a characteristic intracellular distribution which distinghishes lobular carcinoma in-situ from cancerization of lobules. The same histochemical features are seen in the infiltrative phase of the tumour. The...

Since bacterial cells are basically similar to other living cells (Mudd, 1954; DeLamater, 1954) they are also susceptible to the histochemical analyses performed on higher cells. The present study, employing histochemical techniques, may help to resolve some of the problems and areas of disagreement posed by previous investigations in bacterial cytology (Bisset, 1951; Robinow and Hannay, 1953; ...
