[Biometric study of the head region of the Darehshori horse]

Background: Considering differences in head size and shape of different Equine breeds, biometric parameters can be an attribute to a particular race

Objectives: The purpose of the present paper is to give a numerical definition of morphological characteristics of head region of the Darehshori horse

Methods: Twenty mature Darehshori horses were studied biometrically. The ear length, ears distance, eyes distance, head length, lateral head length, head width, rostrum length, distance between two mandibles and lateral face length were measured and the averages were calculated

Results: The average of the related characters were as follow; ear length 16.89, ears distance 12.12, eyes distance 15.79, head length 55.26, lateral head length 49.33, head width 20.42, rostrum length 23.68, distance between two mandibles 10.82 and lateral face length 39.88 centimeter

Conclusions The coefficient of variation of these characters showed that the head length, lateral face length and lateral head length are more reliable characters than the other indices in characterizing the Darehshori horse

Magnetic resonance imaging of feline eye

The purpose of this study was to investigate magnetic resonance imaging [MRI] of the normal feline eye and optic nerves using T[1]-weighted and T[2]-weighted images. A total of 6 healthy female domestic short hair cats age 2-2.5 years and weighing 3.2 +/- 0.4 kg were selected. Magnetic resonance imaging data were collected using GEMSOW [Philips] at a magnetic field strength of 1.5 T. Dorsal, sagittal, and transverse plane images were obtained from left and right eyes. Intraocular structures of the cats visible on T[1]-weighted and T[2]-weighted images include cornea, anterior chamber, posterior chamber, lens, iris, sclera, and chiasma. Cornea was well detected in T[1]-weighted, the iris in T[2]-weighted and chiasma was well detected in T[2]- weighted in dorsal plane. Measurements of the visible structures on T[1]-weighted and T[2]-weighted images did not show any significant difference between the left and right eyes [P>0.05]. MRI provides excellent anatomical detail of the feline eye and optic nerve due to its superior soft tissue contrast and its multiplanar and multislice imaging capability

Computed tomographic anatomy of the abdominal region of cat

The purpose of this study was to identify the anatomic structures of the abdominal region of cat through computed tomography [CT] to be used by veterinary radiologists, clinicians and surgeons. The abdominal region of four cats were scanned twice, with and without using contrast medium in a same position, using high-resolution imaging protocol. Slice intervals were 11 mm and were adjusted so that each vertebra was sectioned at least once. CT cuts taken with and without contrast were compared for accurate identification of specific anatomic structures. Two animals were fixed by routine anatomical method and dissected for use as reference models. Finally, important structures and landmarks were identified and labeled on the CT images

Cleft palate, maxillary oligodontia and croniofacial defects in a sheep [a case report]

A case report of cleft palate with some craniofacial defects in sheep. An approximately 10 months sheep. By anatomical observations of cleaned skull. Cleft palate was observed as an oval hole at the caudal part of the hard palate. Maxillary oligodontia was also observed in both sides of the maxillae. Vomer and some of the facial bones had developedincompletely
