The caput, corpus and cauda regions of the ductus epididymidis consisted of six histological segments that showed regional variations. The postnatal differentiation of the different segments started from birth and progressed till maturity. The simple epithelium at birth gained progressive pseudostratification. Similarly, the appearance of stereocilia, different types of cells in the epithelium ...

It has been suggested that the size of the nuclei of epithelial basal cells can be used in predicting the likelihood of malignant transformation of epithelium. This proposition was assessed in rat palatal epithelium after the carcinogen 4-nitroquinoline-1-oxide had been applied to the epithelium for varying periods of time. No consistent alterations in basal cell nuclear size, including area, p...

Setting: Department of Histopathology, Khyber Medical College Peshawar and Pharmacy, University Peshawar, were utilized conducting this Period: July, 2020 to December, 2020. Material & Methods: Male mice daily...

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: There are reports indicating that among the others, hypoxia is one of the testes threatening factors, which may occur intentionally or accidentally. Hypoxia could be created secondarily after some pathological conditions such as anemia. In this study we aimed to investigate the crocin protective effect on the testes parameters in the animals that were exposed against phenyl hydrazin...

background: histopathological diagnosis of lesions arising from the intake of tobacco is based on subjective evaluation of morphological alterations within the lesional tissue. oral exfoliative cytology is a non-invasive diagnostic technique for early detection of oral premalignant and malignant lesions. morphometric techniques have been advocated as objective and reproducible methods of detect...

In mature rams, the signs of high functional activity thyroid gland are observed in autumn period. An increase diameter follicles (109.1±0.58 microns) is marked, height epithelium (9.6±0.11 and area thyrocyte nuclei (32.8±0.38 μm2) statistically significant (P<0.001). pituitary rams period, there an number tyrotropes. The cytoplasm tyrotropes filled with secretory granules, which reflects le...

background: phthalate esters have been shown to cause reproductive toxicity in both developing and adult animals. objective: this study was designed to assess long-term effects of maternal exposure to di (2-ethylhexyl) phthalate (dehp) on reproductive ability of both neonatal and adult male offspring. materials and methods: 60 female rats randomly divided in four equal groups; vehicle control a...

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...

Morphological and histochemical study of the abomasal epithelium in camel (Camelus dromedarius) wascarried out by light and scanning electron microscopes. The lining of the abomasum was divided into fourregions, i.e. cardiac, pseudocardiac, fundic and pyloric. Our investigation revealed that the cardiac andpseudocardiac regions occupy a wide part of the abomasum in camel and it reaches approxim...
