A cranial window conforming to the contours of the underlying cerebral cortical surface was implanted successfully in 18 cats. Subsequently the left middle cerebral artery (MCA) was occluded inside the sealed cranium and changes in the superficial cortical vasculature were related to measurements of intracranial pressure (ICP), measured extradurally, and to the resulting infarcts. Vascular chan...

Neurons in the trigeminal subnucleus caudalis (Vc) and spinal cord dorsal horn (SDH) play important roles in modulating and relaying pain signals to the higher centers of the central nervous system (CNS). Morphologically, many aspects including a laminated structure, cytoarchitecture and cellular elements in these two central regions are very similar [1 ,2, 3, 4] . Most nociceptive afferents wi...

To the Editor: Lymphangioma circumscriptum (LC) is not a tumor but rather a congenital malformation of the superficial lymphatics. It presents as groups of deep-seated, vesicle-like papules, resembling frog spawn, at birth or shortly thereafter. Also, the sites of predilection are the abdomen, axillae, genitalia, and mouth, particularly the tongue.[1] Klippel-Trenaunay syndrome (KTS) is relativ...

Comparative electron microscope investigations on sections of the lens cortex of the normal, mature rat, rabbit, monkey, and the normal calf reveal similar patterns of intracellular organization. The superficial lens fiber contains a nucleus, mitochondria, endoplasmic reticulum, dense granules, Golgi complex, and a quantity of small structures of low opacity which appear as filamentous and sphe...
