Fixation in Enzyme Histochemistry

Nature, 1965
USE of unfixed frozen sections is confined to enzymes extremely sensitive to denaturation such as the dehydrogenases. Most authors on the subject state or imply that the method introduces the disadvantages of (1) mechanical disruption by freezing and thawing, (2) reduction in quality of tissue detail, (3) uneven section thickness, (4) diffusion of ...

Enzyme Histochemistry of Toxoplasma Gondii

The American Journal of Tropical Medicine and Hygiene, 1964
At present very little is known about the energy metabolism of Toxoplasma gondii except that Fulton and Spooner showed that a suspension of organisms utilizes glucose and oxygen. The organism is difficult to study because it is an obligate intracellular parasite.

Enzyme Histochemistry of Hepatocellular Neoplasms

The American Journal of Surgical Pathology, 1986
We examined a series of hepatocellular neoplasms, including 4 adenomas, 7 hepatoblastomas, and 18 hepatocellular carcinomas (HCC) with enzyme histochemistry in plastic-embedded sections. Our most striking observation was that there was a distinct difference in the staining pattern for alkaline phosphatase (Alk0) in benign and malignant tumors.

Enzyme Histochemistry and Thyroid Neoplasia

American Journal of Clinical Pathology, 1986
The authors have examined the enzyme histochemical staining of surgically removed human thyroid tissue in an attempt to identify markers that might be useful in the histopathologic diagnosis of thyroid neoplasms. Fresh thyroid glands and other tissues were fixed in cold (4 degrees C) 4% paraformaldehyde and embedded in glycol methacrylate.

THE ENZYME HISTOCHEMISTRY OF THE CHOROID PLEXUS

Brain, 1983
Although there is some evidence that extrachoroidal sites for the production of cerebrospinal fluid (CSF) are important, the choroid plexuses in the ventricles contribute the major part of CSF formation. The exact mechanism for CSF production is not fully understood.

Enzyme Histochemistry of Neuroglia

1965
Publisher Summary In this chapter, a survey of the histochemical distribution of oxidative enzymes in neuroglia is given. Oligodendroglia normally contains more oxidative enzymatic activity than astrocytes. Among the individual enzymes involved in the hexosemonophosphate shunt and citric acid cycle, oligodendroglia are particularly rich in the former

Quantitative enzyme histochemistry in the brain

Histochemistry, 1988
Two main groups of quantitative methods are used in the brain to relate enzymatic processes to cellular structures, i.e. the methods of microchemistry and microscopic histochemistry. Microchemistry tries to quantify enzyme activities in very small brain regions by miniaturizing biochemical methods, whereas microscopic histochemistry applies staining ...

Histochemistry of lysosomal enzymes in juxtaglomerular cells

Experientia, 1969
In den Granula juxtaglomerularer granulierter Mausenierenzellen wurde eine saure Phosphatase und eineβ-Glykuronidase-Aktivitat nachgewiesen. (Methoden fur Arylsulphatase und unspezifische Esterase waren negativ.) Es wird der Zusammenhang mit der Lysosomenart der Granula diskutiert.

ENZYME HISTOCHEMISTRY OF NON‐HODGKIN'S LYMPHOMAS

Acta Pathologica Japonica, 1979
Fifty‐two cases of non‐Hodgkin's lymphomas were studied with enzyme histochemical methods. Forty‐four cases of these were also investigated for surface markers with immunological techniques, and results of histochemical, routine histological and immunological observations were correlated.

On the enzyme histochemistry of the renal interstitial cells

Histochemie, 1971
A histochemical study of the renal interstitial cells demonstrates the absence of two of the principal enzymes involved in the citric acid cycle, the cells thus seem to lack the ability to break down fatty acids. On the other hand the renal interstitial cells demonstrate enzyme activity which could be indirect evidence of fatty acid synthesis.
