INVESTIGATIONS IN ENZYMATIC HISTOCHEMISTRY

Studies on Enzymatic Histochemistry

Extraction experiments demonstrated that choline esterase could be removed from microtome sections of tissue with as great facility by 0.9 per cent NaCl as by 30 per cent glycerol. The quantitative distribution of choline esterase through the wall of the pig stomach was studied, and it was found that the epithelial cell region possessed the greatest activity and muscle tissue the least. Pylorus...

STUDIES ON ENZYMATIC HISTOCHEMISTRY XXVI. Tm~ HISTOLOGICAL DISTRIBUTION O1~ CHOLINE ESTERASE IN THE GASTRIC MUCOSA NORMALLY

In previous papers of this series Linderstr¢fm-Lang, Holter, and coworkers have investigated the histological distribution of pepsin (1, 2), acid (2, 3), peptidase (2, 4), and esterase (2, 5) in the gastric mucosa of pigs, and the urease (6) in dog's stomach. The present investigation is a continuation of this work with regard to choline esterase. In view of the well known theory of chemical me...

Intracellular enzymatic histochemistry of the human stomach with special reference to atrophic gastritis.

Histochemistry in Pathologic Diagnosis

By analogy, if Sam Spicer were concerned with athletes, I think he would be the manager of a baseball team. At first glance, he seems to know who the batters are, where his players should position themselves, and what kind of pitches are needed to do the job. What is unfair is that this reader is a middle linebacker by nature and training. Histochemistry contains both the theoretical and the ap...

Studies in Histochemistry

The total dry mass of human erythrocytes was determined by both interference microscopy and x-ray microradiography. The determination of mass per unit area, and calculation of total dry mass per cell were simplified by changing the shape of the cells to spheres which were then flattened to discs of constant thickness when smeared on glass slides for measurement of fixed cells by interferometry,...
