Main Components

The main components of the schistosome tegument were found to be neutral glycoprotein and phospholipid; a small quantity of glycolipid was observed in the male dorsal tegument. The tegument can be differentiated from other schistosome tissues on the basis of enzyme content; three hydrolytic enzymes were shown to be specifically localized in the tegument: alkaline phosphatase, adenosine triphosphatase and indoxyl esterase. It is suggested that these enzymes could be used as intrinsic markers for tegument structures. The subtegumental cells appear to be the major sites of biosynthetic activity since they contain large amounts of RNA and mitochondrial enzymes.

Articular Cartilages

From a comparative study of enzymatic activities in epiphyseal and articular cartilages of 3-week-old rachitic chicks it appears that the activities of pyrophosphatase and adenosine triphosphatase are approximately four times higher in epiphyseal than in articular cartilage. The greater activity of epiphyseal cartilage is even more pronounced in the cases of alkaline phosphatase and hexosamine synthetase. Phosphorylase, on the other hand, is more active in articular cartilage. The significance of these observations is discussed.

Inhibition Studies

The effects of the alkaline phosphatase inhibitors levamisole and R 8231 on p-nitro-phenylphosphatase, inorganic pyrophosphatase and adenosine triphosphatase (ATPase) activities in dentingenically active odontoblasts were studied. The p-nitrophenylphosphatase and inorganic pyrophosphatase activities were inhibited, while 40% of the ATP-splitting enzyme activity remained under the assay condition used. This finding, togeather with earlier studies, indicates that at least two different phosphatase are active at alkaline pH in hard tissue-forming cells; on nonspecific alkaline phosphatase and one specific ATPase. The ATPase activity is uninfluenced by ouabain and ruthenium red and is activated by Ca-2+ ions.

Dorsal Aspect

An apocrine hidrocystoma occurring on the finger of a 55-year-old man is reported. The lesion presented as a solitary, painless cystic nodule on the dorsal aspect of the middle phalanx of the index finger. Apocrine hidrocystoma is a benign tumour developed from apocrine sweat glands, but the location of the lesion was, however, not consistent with reported locations of apocrine glands in the adult.

Histochemical Tests

1. Histochemical tests have been applied to the socalled sweat glands and their secretions of Zebu and Ayrshire cattle, the former to only a limited extent.2. For skin specimens of Ayrshire cattle positive reactions were obtained for ribonucleoprotein, arginine and alkaline phosphatase. Negative reactions were obtained for desoxyribonucleoprotein and acid glycerophosphatase.3. Neither the sweat glands of Ayrshire cattle nor those of Zebu cattle gave positive reactions for fats, lipids or cholesterol and its esters, although these were all present in the sebaceous glands of both breeds. Detectable amounts of phospholipid were not found in the sweat glands of the Ayrshire cattle and their secretions.4. The chemical composition of the secretion of bovine sweat glands differs markedly from that of human eccrine or apocrine sweat glands in not containing detectable amounts of glycogen, lipids and associated compounds or iron.
