    Notes: [Auszug] In 8-12-week-old male CBA mice the proportions of lymphocytes which were able to bind FITC-PNL in cell suspensions from thymus, spleen, peripheral lymph nodes and bone marrow (Table 1) were found to be similar to those previously reported2,3. However, the observation that 20% or more of Peyer's ...

    Notes: Abstract The morphology of vitreous membranes from enucleated human eyes containing vitreous haemorrhage was studied by electron microscopy. Three types of membrane are described, based on their cellular composition: haematogenous, fibroblastic and neovascular. Simple vitreous haemorrhages usually failed to stimulate a fibroblastic cellular response, whereas vitreous blood clots in eyes with penetrating injuries were frequently invaded by choroidal and/or scleral fibroblasts. Fibroblast-like cells were also found in neovascular membranes, but not as a major cellular component. They had the appearances of astrocytes, suggesting an origin from the retina or optic disc in association with the intravitreal new vessel growth. These data suggest that two factors are necessary for intravitreal fibrosis: an adequate port of entry for cellular invasion and a suitable substratum on which migrating cells can crawl.

    Notes: Abstract The formation of vitreous membranes after intravitreal haemorrhage was studied in rabbit eyes. Early detachment of the posterior vitreous was followed by the formation of large cellular membranes, composed of aggregated giant macrophages within fine collagen sheets. Progressive reabsorption of the cellular material resulted in acellular membranes composed of endogenous vitreous collagen. Fibroblastic activity was not observed, and it was considered that the vitreous body, particularly its hyaluronic acid component, may present a barrier to the invasion of fibroblasts and other cells during the resolution of vitreous clots.

    Notes: Abstract Experimental studies of ocular inflammation induced by endotoxin have been performed almost exclusively in rabbits. Although the rat has been considered refractory to both the systemic and local effects of endotoxin, the present study has shown that intravitreal injection of endotoxin evoked a characteristic acute inflammatory response which was reproducible and dose-dependent. In addition, a consensual ocular response in the control eye occurred which was less severe but also dose-dependent. Preliminary investigations support the view that consensual responses of this nature may be mediated by a nervous reflex arc mechanism. Sequential histological analysis revealed a marked polymorphonuclear cell infiltration of most ocular tissues in the early stages, while mononuclear cells predominated after 3 days. Widespread intravascular microthrombi were also observed, particularly in the ciliary vessels. Recovery, however, was usually complete by 7 days.
