background: the aim of the present study was to evaluate the efficacy of autologous serum eye drop in treatment of recurrent corneal epithelial defect. m aterials and methods: fourteen patients with recurrent corneal epithelial defect were studied. autologous serum was prepared from the patients and diluted in 20% normal saline. the patients were instructed to use the autologous serum every six...

background: this study was undertaken to establish the characterization of cultured oral mucosal epithelium and introducing them as an alternative source for reconstruction of ocular surface disease. methods: human oral epithelial cells were cultured on simple media (dmem/hf12) as control and co-cultured on mitomycin c-treated 3t3 feeder layer, on the amniotic membrane (am) without nitrocellulo...

we present a case of epitheloid sarcoma that was referred with a 2×3cm ulcerated lesion on the right ankle and edema of the lower leg. foot drop of the right side was present that had caused walking difficulty. after a few months, he developed several sporthricoidal nodular lesions on the medial aspect of right thigh, inguinal lymphadenopathy, weight loss, anorexia and respiratory symptoms. che...

the cellular organization of the olfactory epithelium of puntius sarana (hamilton, 1822) was explored by means of optical and scanning electron microscopy. the oval shaped olfactory rosette was composed of 26-28 primary lamellae distributed from both sides of the central raphe. the sensory epithelium confined chiefly on the linguiform processes of the lamella and rest of the portion consisted o...

background and aims. several diagnostic methods are being employed to detect benign and malignant lesions, one of which is silver nitrate staining for organizer regions. the number of nucleolar organizing regions (nors) can be used to show the degree of cell activity or metabolism in pathologic lesions. this study was designed to evaluate nors as determinants of precancerous and squamous cell c...

The microanatomy of the intestinal epithelium in the Chinese soft-shelled turtle (CST) was studied by light and transmission electron microscopy (TEM). The small intestinal epithelium (SIE) was single layered or pseudostratified. The enterocytes contained mitochondria or mitochondria and lipid droplets. The enterocytes were arranged tightly in the apical parts of epithelium and connected by des...

nutritive value of rumen epithelial scraping (rep) was assessed using in sacco and in vivo procedures. concentrates were so formulated that 0% (a), 35% (b), 70% (c), and 100% (d) of soybean meal (sbm), were replaced (weight for weight) with rep. in a completely randomized design, 16 west african dwarf (wad) goats were randomly allocated to the experimental diets to assess feed intake and digest...

calcifying epithelial odontogenic tumor is a rare odontogenic neoplasm. its occurrence in the maxillary sinus is very rare. maxillary tumors tend to be locally aggressive and may rapidly involve the surrounding vital structures.  we report a case of calcifying epithelial odontogenic tumor involving maxillary sinus in a 48 years old female patient with the oral mucosal involvement. the purpose o...

background: an increase in the number of intraepithelial lymphocytes (iel) in the duodenal mucosa is an important criterion for the histological diagnosis of celiac disease (cd). we determined the normal range for intraepithelial lymphocytes (iel) in the second part of duodenum in healthy iranian population. materials and methods: four biopsy samples of the endoscopically normal appearing mucos...
