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; ...

The activities of 13 enzymes in 40 carcinomas of the large bowel have been studied using histochemical techniques. Five enzymes-non-specific esterase, monoamine oxidase, succinate dehydrogenase, cytochrome oxidase, and acid phosphatase-commonly show much less activity in the tumours than in adjacent normal colon. The tumours have been classified based upon the number of enzymes which show marke...
