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 the chick embryo.
Conclusion: The chick embryo cell antirabies vaccine can cause bilateral neuroretinits which has not been reported previously.

In chick embryos prior to primitive streak formation, the outermost extraembryonic region, known as the area opaca (AO), was generally thought to act only by providing nutrients and mechanical support to the embryo. Just internal to the AO is a ring of epiblast called the marginal zone (MZ), separating the former from the inner, area pellucida epiblast. The MZ does not contribute cells to any part of the embryo but is involved in determining the position of primitive streak formation from the adjacent area pellucida epiblast.

During development, amniote vertebrate embryos transform from a flat sheet into a three-dimensional cylindrical form through ventral folding of the lateral sides of the sheet (the lateral plate [LP]) and their fusion in the ventral midline. Using a chick embryo slice system, we find that the flat stage is actually a poised balance of opposing dorsal and ventral elastic bending tensions. An intact extracellular matrix (ECM) is required for generating tension, as localized digestion of ECM dissipates tension, while removal of endoderm or ectoderm layers has no significant effect.

The evaluation of chlorhexidine-carrier nanosystems based on iron oxide magnetic nanoparticles (IOMNPs), has gained significant attention in recent years due to the unique properties of the magnetic nanoparticles (NPSs). Chlorhexidine (CHX), a well-established antimicrobial agent, has been widely used in medical applications, including oral hygiene and surgical antisepsis. This study aims to report an in vitro and in ovo toxicological screening of the synthesized CHX-NPS nanosystem, of the carrier matrix (maghemite NPSs) and of the drug to be delivered (CHX solution), by employing two types of cell lines-HaCaT immortalized human keratinocytes and JB6 Cl 41-5a murine epidermal cells.

The objective of this study is to assess the embryological and morphometric development of the chick cerebrum during specific incubation periods. The cerebrums of 24 Babcock White Leghorn chicks, six each from the 10th, 13th, 16th and 21st days of the incubation period, were used in the study. After removing the heads of fixed embryos from the upper edge of the atlas, the brains were taken out of the cranial cavity.

Background And Objective: This study aimed to determine the effects of in ovo formula product injection on hatching parameters, chick quality, small intestinal development and ileum histology of breeder hen eggs.
Methods: A total of 400 fertilised eggs were obtained from the Atak-S parent flock at 42 weeks of age for the experiment. The experiment was designed in two groups: a control group (C), in which no injection was performed, and the other group in which a solution containing formula products at concentrations of 1.
