General ultrastructural properties of the atrioventricular valve and the endo- and myocardium of the tigerfish Hydrocynus forskahlii add further information to our knowledge of fish heart morphology. Small pieces of tissue from the heart of H. forskh

Tissue of commercially prepared tissue heart valves were evaluated and compared with aluminium treated, fixed porcine valve tissue in vitro (tensile strength, scanning and transmission electron microscopy) and in vivo (calcification potential after s

A patient with a retained intra-ocular foreign body had a lens extraction for lenticular chalcosis. The lens capsule, examined under an electron microscope, showed copper particles deposited in the basement membrane. The lens capsule and foreign body

The relative sensitivities for the various in vivo and in vitro tests for platelet activation are unknown. This was studied in a baboon model where limited and more substantial injury to the vascular endothelium was inflicted. The endothelium of a se

Summary. The extent of the ‘collection injury’ sustained by platelets during labelling with In-lll-oxine was investigated in three matched pairs of beagle dogs. The influence of the procedure on the survival, kinetics, in vivo distribution and fa

The term 'gestational trophoblastic disease' includes hydatidiform mole (invasive and non-invasive), choriocarcinoma and a rare condition initially called trophoblastic pseudotumour and more recently placental site trophoblastic tumour. Originally th

The relationships between the volume of human platelets and their cytoplasmic organelles were studied by morphometric analysis. Platelets were separated into four density-dependent subpopulations on an arabino-galactan gradient. In vitro activation o

Potassium phosphate, Magnesium chloride and T6 as blocking agents on tissue valve calcification have been studied in vitro and in vivo. In vitro tests indicate that untreated leaflets (control group) tend to calcify significantly more than treated le

In this study the light microscopic and electron microscopic findings in two renal cell carcinomas with spindle-cell elements are described. The ultrastructural features of the spindle-cell element of sarcomatoid renal cell carcinoma have previously

Factors influencing labelling of human platelets with 111Indium-8-hydroxyquinoline ([111In]-oxine) in a physiological saline medium were investigated. The efficiency of labelling is influenced by time of incubation, concentration of oxine, and pH of
