BACKGROUND The Optic nerve is rarely involved after sheep brain anti-rabies vaccination in the form of retrobulbar neuritis or papillitis. Bilateral neuroretinitis after chick embryo cell antirabies vaccination has not been reported. CASE PRESENTATION We report the case of a 56 year old male who developed bilateral neuro-retinitis following three injections of antirabies vaccine prepared from...

Objective(s) In this study we investigated the expression of GABAA receptor subunits during brain development. These receptors may change in the embryonic chick forebrain. Materials and Methodes The expression levels of four types of GABAA receptor gamma subunits (γ1, γ2, γ3 and γ4) were quantified in the embryonic chick forebrain at 32 hr, 3, 7, 14, and 20 days of incubation and day one aft...

We report here that cells present in embryonic chick retinal monolayer cultures express differentiated properties characteristic of chick cones developing in vivo. Cell suspensions from 8-d chick embryo retina (a stage when photoreceptor differentiation has not yet started) were cultured for up to 7 d in low density, glial-free monolayers. Under these conditions, monopolar cells represent appro...

We tested the hypothesis that parental effort modulates the magnitude of corticosterone and prolactin responses to stress in a long-lived bird, the Black-legged kittiwake (Rissa tridactyla). To do so, we compared corticosterone and prolactin responses to capture/restraint stress between chick-rearing birds and failed breeders (no parental effort). We predicted that (1) the increase in plasma co...

During normal development chick motoneurons have been shown to project selectively to appropriate muscles by responding to a series of cues, both specific and nonspecific, within the limb. We tested the ability of motoneurons from another avian species, the Japanese quail, to respond to these cues by transplanting chick limb buds onto quail embryos and quail limb buds onto chick embryos between...

Antibodies to pure lysyl hydroxylase from whole chick embryos were prepared in rabbits and used for immunological characterization of this enzyme of collagen biosynthesis. In double immunodiffusion a single precipitation line was seen between the antiserum and crude or pure chick-embryo lysyl hydroxylase. The antiserum effectively inhibited chick-embryo lysyl hydroxylase activity, whether measu...

A blocker of postsynaptic acetylcholine receptors was isolated from venom of the Eastern green mamba Dendroaspis angusticeps, by gel filtration, ion-exchange and reverse phase high performance liquid chromatography. The isolated component blocks neuromuscular transmission and responses to exogenously applied acetylcholine in isolated chick biventer cervices preparations. These results suggest t...

Gli genes encode a family of zinc finger transcription factors that mediate signaling by Hedgehog proteins. We have cloned the chick Gli3 gene and studied its expression in developing chick limbs. Gli3 expression is highly similar to that of chick Gli2. Gli3 mRNA is evenly distributed in the early limb mesenchyme and subsequently downregulated in the posterior mesenchyme by the polarizing activ...
