Epibulbar osseous choristoma: a case report.

Peribulbar osseous choristoma is a benign, solid nodule; it is a subtype of epibulbar choristomas (belongs to single tissue choristomas), consisting of pure bony tissues. Epibulbar osseous choristoma is the rarest subtype of epibulbar choristomas, with only 65 cases reported since the mid-19th century; so, the rarity of the disease drove me to report it. A 7-year-old female presented with a painless left ocular superotemporal mass, which was present since birth and located under the conjunctiva.

Comparison between Antimicrobial and Antibiofilm Activity of Exopolysaccharides (EPS) Extracted from and against Oral Bacteria.

Due to the increased resistance to antibiotics and chemical biocides, the use of bacterial exopolysaccharides has been considered. The objective of the current study was to investigate the strength of the antibacterial and antibiofilm activity of EPS extracted from and because previous studies showed there were structural differences between EPS, during this study, EPS extracted from and by ethanol precipitation method and estimated antibacterial and antibiofilm activity against several Oral Bacteria (, , , , in different concentration as (100,150,200,250,300 mg/ml ), the results showed carbohydrates rate in extracted EPS from and were recorded was 85, 80 % respectively.The concentration 100 and 150 mg/ml for EPS from and , there was no inhibitory effect, except in (1.

Histopathological and immunological study of rats liver hydatid cysts isolated from human, sheep, goat and cows.

In endemic places, liver hydatidosis is a life-threatening health issue. Many consequences such as hepatomegaly, infiltration with inflammatory cells and histopathological changes might arise as a result of liver hydatidosis. This study aimed to look into pathogenic changes in the livers of the rats that experimentally infected with hydatid cysts.
