1) Three different types of muscle fibers were clearly distinguished in the intercostal muscles and the diaphragm of human, cat and rat by histochemical demonstration of oxidative enzymes, phosphorylase and glycogen. 2) The intercostal muscles and diaphragm each presented dissimilar patterns of the muscle fibers. The diaphragm did not show any definite correlation between the diameter and the h...

Experiments were carried out to assess the susceptibility of normal and inflammatory bowel disease rectal mucus to desulphation and desialation by faecal extracts and by bacterial sialidase. The effects were assessed histochemically using a combined high iron diamine (HID) and alcian blue (AB) stain for sulphomucins and sialomucins. Rectal mucus in biopsies from controls (irritable bowel syndro...

Metastatic neuroblastoma cells in bone marrow aspirates were examined by the formaldehyde induced fluorescence histochemical method. With this method we could easily identify abnormal cells as metastatic neuroblastoma cells by observing catecholamine green colored fluorescence in their cytoplasma. This formaldehyde induced fluorescence histochemical method is significantly useful for the diagno...

A histochemical demonstration of cyclic 3',5'-nucleotide phosphodiesterase in retinal photoreceptor outer segments is reported for the first time. The enzyme appears to be located on outer segment lamellae. It is not found in adjacent inner segment or nuclear regions. This histochemical localization is consistent with previously reported biochemical studies showing high phosphodiesterase activi...

Aortic lipolytic (lipoproteinolytic) and esterolytic activity of various species were investigated by biochemical and histochemical methods. Lipolytie and esterolytic activities in the aorta of species susceptible to experimental atherosclerosis are lower than in the rat, a very resistant species. The histochemical technics permitted the localization of enzymatic activity in individual layers o...

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 ...

The authors have applied the thiochrome method for determining thiamine to histochemical investigations and could observe the localization of thiamine in cells and tissues (1-6). Independently of our study, v. Muralt (7) had already reported a investigation on histological pictures of thiamine in peri pheral nerves by the thiochrome method, which was however unavailable to the authors at that t...
