The disruption of prepulse inhibition (PPI) in rats by dopamine (DA) agonists is used to study the neural basis of strain differences in dopaminergic function. We reported that, compared to Long-Evans (LEH) rats, Sprague-Dawley (SDH) rats are more sensitive to the PPI-disruptive effects of the direct D1/D2 agonist apomorphine (APO) and the indirect DA… (More)
Surgical excision followed by radiotherapy has been the recommended treatment for paraplegia due to extramedullary hematopoiesis in patients with beta-thalassemia. The authors report the successful treatment of such a case by partial excision and repeated blood transfusions.
Intratubular cells with numerous refractile eosinophilic cytoplasmic granules were identified in a cryptorchid testis from a 17-year-old boy. The staining properties of the granules and the ultrastructural features were studied. The accumulation of lipid or lysosomal inclusions accounted for the observed cytoplasmic granules. These granular cells were… (More)
