Introduction: Genital system is important herd in animal's creation. It is necessary for animal reproduction. Mammal has two sex in genital system such as male and female in separated animals. Animal reproduction destroyed by disorder of genital system. In this case, animals cannot produce an animal similar to them. Finally it cause overthrow a species of animals. Methods: Histomorpholog...

Glycogenic acanthosis of the esophagus is a common benign entity characterized by multifocal plaques of hyperplastic squamous epithelium with abundant intracellular glycogen deposits (1). At esophagoscopy these lesions appear as slightly raised grey-white plaques which are usually 2-10 mm in diameter and may be confluent. Although they may involve any segment, the literature suggests that are m...

objective: cyclophosphamide (cp) is a chemotherapy drug which causes deleterious effects on testicular tissue and increases free radicals in the body. the aim of this study is to investigate the protective effects of ethyl pyruvate (ep) on testicular improvement in cp treated animals. materials and methods: in this experimental study, 15 male mice (6-8 weeks) were divided into 3 groups. the con...

OBJECTIVE In the dog biopsy samples from the gastro-esophageal junction (GEJ) are rarely obtained during routine gastroscopy. The aim of this pilot study was to assess the histological quality of endoscopic biopsies sampled from the canine esophagus and cardia. It was hypothesised that it is possible to sample adequate specimens from these sites. MATERIALS AND METHODS For this purpose 10 dogs...

background: keratinocyte stem cell is one of the adult stem cells that inhabits the skin and contributes to skin function and renewal. adult stem cells are best defined by their capacity to self-renew, and to maintain tissue function for a long period of time. these findings indicate the importance of these cells for clinical applications including regenerative medicine, tissue engineering and ...

The present study was designed to investigate the histochemical developmental changes of proventriculus at pre-hatching and post-hatching in northern bobwhite quail periods 11- 15-days addition 14- 21-days post-hatching. composed four tunics is tunica mucosa, sub-mucosa, muscularis, serosa. mucosa lined with simple columnar epithelium height increases age also thickness submucosa filled provent...

the drilling is well known as one of the most common hole making processes in the industry.due to close tolerance requirement for drilled holes in the most of work pieces, onlinecontrolling of the diameter of drilled holes seems to be necessary. in the current work, an onlinedimensional controlling system was developed for drilling process. doing this, drilling processwas executed in different ...

Histological development of digestive tract of the Caspian salmon, Salmo trutta caspius, from hatching to 6 month post-hatching was studied using light microscope. The digestive tract of newly hatched larvae was a simple, undifferentiated tube which continued from mouth to anus. In 10 days post hatching larvae, the alimentary canal became more differentiated and secretion was started activity, ...
