Abstract
The present study is concerned with histological structure and histochemical composition of hydatid cyst layers of Echinococcus granulous from liver and lungs of naturally infected human being. Through histological techniques the laminated layer appeared as series of contiguous laminations emerging from germinal layer like U shape such a result is rarely obtained. A comparative study also deals with a histochemical components of both layers of the cyst including neutral carbohydrates glucose, glycoprotein, proteins , lipids , deoxyribonucleic acid and calcium. The histochemical study of the cyst layers laminated and germinal, has revealed that they consist of complex compounds lik neutral mucopolysaccharids, glucose , glycoproteins, glycolipids and 1, 2 glycols materials, in addition to the more hyaluronic acid, sulphated and carboxylated mucopolysaccharirs with various concentrations in both laminated and germinal layers, with proteins, particularly bound proteins were also observed. It is noticed that the germinal layer contained lipids particularly lipoproteins and phospholipids and calcium more than the laminated layer. It was also observed that the laminated layer lacks glycogen. On the other hand, the germinal layer contains glycogen, as well ascalcareous corpuscles and deoxyridonucleic acid .
