The conjunctiva of the adult Sprague-Dawley rat was studied by light microscopy of 3 micron glycol methacrylate sections of whole eyes with lids and by electron microscopy of conjunctiva from the lower fornix. Rat conjunctiva is unique among species studied. All the superficial epithelial cells are squamous cells rather than polyhedral or columnar cells.(More)
Leukocytes and platelets, freshly isolated from normal human blood, were tested cytochemically for glucose-6-phosphatase (G-6-Pase) by a modified Wachstein-Meisel method. The enzyme was present in the endoplasmic reticulum (ER) and perinuclear cisternae of all five types of leukocytes and in the ER of platelets. The reaction product from the cytochemical(More)
Two kinds of surface specializations of chlamydiae have been described: hemispheric projections and spikelike rods. We undertook the present studies to demonstrate chlamydial ultrastructure in greater detail in conventional thin-sectioned specimens. Chlamydia trachomatis (LGV strain L2/434/Bu), cultured for 40 h in L929 mouse fibroblasts, was fixed in(More)
PURPOSE These studies were undertaken to establish an animal model for use in studies of ocular toxoplasmosis. An animal model is needed to examine the development, progression, and resolution of ocular Toxoplasma infections and to study the effects on the disease of currently used and experimental therapies. METHODS Cysts of the ME 49 strain of(More)
The living parasites in Toxoplasma cysts cannot be eradicated by current therapy and maintain latent infections for many years. Relatively little is known about encysted Toxoplasma. We therefore undertook studies using mice infected with the avirulent ME 49 strain of Toxoplasma. The bradyzoites in young (12- to 17-day-old) cysts contained the same(More)
The spread of herpes simplex virus (HSV) was studied in the mouse central nervous system (CNS) after ocular inoculation. Sites of active viral replication in the CNS were identified by autoradiographic localization of neuronal uptake of tritiated thymidine. Labeled neurons were first noted in the CNS at 4 days postinoculation in the Edinger-Westphal(More)
Cytochemical and biochemical investigations have revealed glucose-6-phosphatase (G-6-Pase) activity in Kupffer cells of the liver. To determine whether other mononuclear phagocytes are also reactive for G-6-Pase, rabbit bone marrow, blood, and alveolar macrophages were tested for G-6-Pase by a modified Wachstein-Meisel method and prepared for electron(More)
The double addition of Grignard (alkyl, aryl, alkenyl, alkynyl) reagents to acyl cyanohydrins was performed under unusually smooth conditions with a concomitant O-N acyl transfer, providing a very simple and general access to α,α,α-trisubstituted amides.
