Introduction: First branchial cleft anomalies manifest with duplication of the external auditory canal.   Case Report: This report features a rare case of microtia and congenital middle ear and canal cholesteatoma with first branchial fistula. External auditory canal stenosis was complicated by middle ear and external canal cholesteatoma, but branchial fistula, opening in the zygomatic root and...

by determining normal ranges of spinal canal diameters we can make early diagnosis in persons who have lower diameters of spinal canal. these persons are predisposed to spinal canal stenosis that is a major cause of spinal radiculopathies. in different studies performed in several countries, minimum and maximum ranges of spinal canal diameters were different for each population. in this study, ...

PRESENT-DAY knowledge of the physiology of digestion in ruminants is very limited and to a great extent it is based on anatomical deductions. Some of these are doubtless correct; but many of them must be regarded merely as speculations until such time as adequate experimental proof is brought forward. It was with the object of providing this proof that the present work was undertaken. The exper...

Microorganisms are very important in the initiation of pulpo-periapical pathosis. Due to the complexity of the root canal system, the mechanical instrumentation of the root canal system should be supplemented with proper canal irrigants and medicaments. It has been revealed that due to the interactions of canal irrigants and medicaments with dentin and contents of the canal system, the antimicr...

background gastrointestinal and liver diseases (gild) are among the most common causes of morbidity in iran and constitute a substantial proportion of mortality which imposes enormous economic consequences. our purpose is to collect information and report current statistics on physician visits, hospitalizations, and deaths due to common gild in iran. methods data on the leading causes of death ...

The digestive organs in decapodiform cephalopod species morphologically vary by individual lifestyle. We examined the following six species of adult decapodiformes cephalopods representing different habitats: Todarodes pacificus, Loligo bleekeri, Loligo edulis, Watasenia scintillans (pelagic), Sepia lycidas and Euprymna morsei (benthic). L. bleekeri and L. edulis possess a bursiform cecal sac c...
