Background: Diabetes mellitus can lead to histomorphometrical changes in the brain. Recent studies have shown that Aloe vera gel has antioxidant and neuroprotective effects, which is independent of glucose-lowering effects. Objectives: The present study aimed to investigate the effects of A. vera gel on histomorphometrical changes of cerebellum fol...

BACKGROUND: As regards the role of the hind limb in propulsion, it is obvious that the tarsus forms a powerful center movement, it begins upon the point of the hock that the powerful extensor muscles which propel the body exert much of their energy. Tarsus injuries of water buffalo are the commonest limb joint disorders. OBJECTIVES: The aim of this...
Article
Background: Six liner measurements of constant cranial cervical ganglion (CCG), three inconstant main, first, second middle cervical ganglia (MG, MG1, MG2), and interganglionic branch (IGB) were taken to determine normal fetal growth rates and patterns of cervical sympathetic trunk (CST) components in different gestational ages. Materials and met...
Article
BACKGROUND: The study of animal development by a dynamic perspective on gross anatomy often provides amplified pattern to reveal the more complex anatomy of the adult. This is especially helpful in understanding a system whose components drastically change their relation positions during developmental growth, such as urogenital organs. OJECTIVES: T...

The osteometric evaluation was done on 40 macerated metapodial bones of 10 male adult one-humped camels by using 16 linear measurements. There was no difference between the right and left metapodial bones both in the fore and hind limbs. Means of the most parameters in the metacarpus were greater than those of the metatarsus. In all metapodial bone...

The Iranian deer, known as Dama Dama mesopotamic, is a subtle deer of European deer. The generation of this species was endangered due to over exploitation and myiasis, but with measures taken out of danger of extinction in Iran was saved. Currently, this valuable animal is one of the protected species that is stored in the area of Iran, including...

The results showed that after birth in carnivores, the umbilical artery remained merely the round ligament of the bladder while in the equidae in addition to round ligament of the bladder, the cranial bladder artery also occurs, which is responsible for the blood flow to the apex and of bladder. But in ruminants, in addition to the round ligament o...

The tarsal joint is anatomically complex region with many short bones, joints, ligaments, and tendons. The joint lesions of the water buffalo limbs are the most commen lesion encountred in the clinics. In addtion, the tarsal joint is a region of trumatic injuries, and joint affections due to lack of approrpoite soft- tissues covering. The aim of th...
Article
Background: The foramen magnum (FM) is an important landmark of the skull base and a transition zone between spine and skull as well as its close relationship to the brain and the spinal cord. So the FM has gained considerable interest due to its comparative anatomy, ontogeny, clinical, and animal breeding viewpoints. Objectives: The aim of this st...

Enrofloxacin is a synthetic chemotherapeutic agent from the class of the fluoroquinolones that is widely used to treat bacterial infections. It is metabolized to ciprofloxacin in the body as active metabolite. Fluoroquinolones change in the articular cartilage, especially with high doses and more than two weeks use. So, due to relatively excessive...
Article
The detailed morphology and topography of the cranial cervical ganglion (CCG) with its surrounding structures were studied in 10 sides of five heads of adult one-humped camel to determine its general arrangement as well as its differences and similarities to other animals. The following detailed descriptions were obtained: (1) the bilateral CCG was...

Dromedary camels are large even-toed ungulates which are well adapted to life in large deserts. Examinations of their feet have revealed many structural peculiarities. We have measured the digital bones of the dromedary in order to determine whether there are morphometric variations in the digital bones between the lateral and medial sides in indiv...

Nearly completed conjoined or fused symmetrical twins are generally called diplopagus. Sheep conjoined twins have been reported less than cow. An apparently female conjoined twin lambs was examined based on external and internal features. In radiology, two vertebral columns and two pairs of the ribs were seen. Only two heads and two necks were sepa...
