infectious bursal disease (ibd), a highly contagious and devastating disease in young chicken, is causedby infectious bursal disease virus (ibdv). to improve the immunogenicity of recombinant ibdv subunitvaccine, an attempt was made to find a new way to prepare ibd vaccine containing glycosylated mvp2antigen. firstly, ibdv mvp2 gene (with a nucleic acid sequence encoding b cell epitope of ibdv(...
Introduction. Histopathological findings of various inclusions were reported in the central nervous system amyotrophic lateral sclerosis (ALS) patients but not peripheral nerves. Case report. We present a 66-year-old man with lower limb weakness, later development weakness upper limbs and loss sphincter control. Neurological examination showed affection both motor neurons. He had paresthesia on...
Rat submandibular mucin (RSM) was purified by acid precipitation, then alcohol precipitation of the 30000g supernatant of gland homogenate, followed by column chromatography on Sephadex G-200. The mucin, which was eluted in the void volume, had an amino acid profile typical of a salivary mucus glycoprotein with high proportions of threonine, serine and proline (48.8% of total amino acids), and ...
Lipoid proteinosis (LP) is an extremely rare autosomal recessive genodermatosis, characterized by persistent hoarseness and classical skin lesions. Amorphous hyaline depositions may affect any organ, but mainly the face extremities. These cause limitations in tongue movement, hence, difficulty speaking. Biopsies of lesions usually show massive deposits homogeneous, acidic, hyaline-like material...
AIMS To investigate the histopathological changes of rabbit corneas after laser in situ keratomileusis (LASIK) and to evaluate the corneal wound healing process. METHODS A LASIK was performed on white rabbit eyes. Postoperatively, rabbits were killed on days 1 and 7, and at 1, 3, and 9 months. RESULTS Periodic acid Schiff (PAS) positive material and disorganised collagen fibre were seen alo...
A 52-year-old man presented with diarrhea and 20 kg weight loss in one year. Enteroscopy showed diffuse yellow-white shaggy mucosa in the duodenum and jejunum. Biopsies of the duodenal mucosa revealed massive infiltration within the lamina propria by foamy macrophages strongly positive for periodic acid-Schiff stain. Electron microscopy demonstrated numerous bacilli within macrophages of the la...
Pulmonary alveolar proteinosis (PAP) is a rarely seen disease of the alveoli, characterized by accumulation of proteinous material, which stains positive with periodic acid Schiff, in the alveoli. Secondary PAP may develop as a result of occupational exposure to materials such as silica and indium. In the paper, together with a review of the relevant literature, we present an uncommon case of a...
