background: magnetized water has made many improvements in industry, agriculture and medicine. however its utilization in medicine still remains controversial. objective:  in this study we aimed to investigate the effects of magnetized water on height of epithelial cells in pre-implantation stage endometrium and fallopian tube and number of corpus lutea in female mice. materials and methods:  e...

PURPOSE To clarify the morphological changes in the rat lens after irradiation with continuous low doses of x-ray at different intervals. METHODS Male Wistar rats at the age of 8 weeks were irradiated with three doses of 2 Gy at intervals of either 1 week or 1 day. Over the period from the first week to the eighth week after irradiation, the eyeballs of the rats were enucleated progressively ...

In this study, structural changes of liver and gills the crucian carp after one-month exposure to different concentrations alkylbenzene sulfonate (AS) surfactants were evaluated by pathological sections organs. The results indicated that effect AS on was mainly reflected in nucleus swelling, cell membrane rupture, blurring boundaries, appearance vacuoles cytoplasm. Meanwhile, occurs gill filame...

Introduction: Amniotic membrane, the innermost layer of extra-embryonic tissue, contains mesenchymal and epithelial stem cells. The amniotic mesenchymal cells have the capability of inhibition of growth of cancer cells. In this research, the effects of amniotic epithelial cells on the viability of cancer cells and the role of apoptosis in this procedure were evaluated. Methods: Amniotic mem...

amniotic epithelial cells (aecs) possess unique characteristics, which make them a suitable source for cell-based therapeutic strategies. aecs have stem cell properties with low-immunogenicity (due to expressing hla-g molecule and absence of mhc class i and ii antigens) and no ethical problems, as well as availability in sufficient numbers, which can be obtained from a placenta. we have recentl...

The morphology of retinal photoreceptor layer was studied in continuous light-exposed and dark-adapteddomestic male cats (Felis catus). The eyes of 12 healthy adult cats (4 in continuous light-exposed group, 4 in continuous dark-adapted group, and 4 in control group) were routinely fixed and studied by electron microscope. Results showed that the general structure of photoreceptor layer in this...

background: keratinocyte growth factor (kgf) is a potent epithelial mitogen that acts by binding the kgf receptors (kgfrs) expressed on epithelial cells and regulates proliferation and differentiation. the objective of this study was to investigate the expression of kgf in the epithelium in oral precancer. materials and methods: archival tissues of oral submucous fibrosis (smf) and leukoplakia ...
