The giant neurosecretory cells in the thoracic ganglion of the adult and juvenile crab, Potamon magnum magnum (Pretzman) were histochemically investigated. The secretion is mainly proteinaceous in nature, containing considerable amounts of acid mucosubstances, sulphate esters, lipids and a little carbohydrate but no glycogen. The detailed nature of(More)
Malignant periprosthetic metastasis is a very rare yet important cause of painful joint arthroplasty. This study presents a case in which periprosthetic osteolysis following total hip replacement (THR) occurred as a result of metastatic mesothelioma. After a THR and revision THR, histopathology confirmed the diagnosis of metastatic mesothelioma. Primary(More)
The epidermis of the fully mature earthworms, Dendrobaena atheca, has been investigated both histomorphologically and histochemically. The epidermis is constructed of two main cell categories: the glandular and nonglandular. The former comprises albumen, and small and large mucous cells whereas the latter includes supporting, basal and sensory cells. All(More)
The saccus vasculosus of Cyprinion macrostomus is made up of coronet and supporting cells. Neurones are not observed. The luminal surface of the coronet cells exhibits hair-like protrusions. The saccus vasculosus is mainly concerned with a secretory function. Plenty of secretory material is seen in the lumen. PAS and alcian blue tests are positive for the(More)
Only four types of the secretory neurones were observed in the thoracic ganglion of the fresh water crab, Potamon magnum magnum (Pretzman). These cells are classified as A, A', B and C types. Our results also confirmed that the B and B' types of cells (BAID et al. 1968) are one and the same type, the B cells. The B cells are of two forms, with and without(More)
The histochemistry of the neurosecretory material of the PF-positive neurosecretory cells of the cerebral ganglion of the adult and juvenile crab, Potamon magnum magnum (Pretzman) has been investigated. The PF-positive neurosecretory material is proteinaceous and contains considerable amounts of cystine; it is associated with significant amount of(More)
The present study deals with acid and alkaline phosphatases activity determination in B cells of the thoracie ganglion of Potamon magnum magnum. Intense alkaline and acid phosphatases activity is seen in the neurosecretory granules as well as in the neural sheath. Acid phosphatase activity unlike alkaline phosphatase distribution, is seen in form of(More)
