This report deals with the ultrastructural changes observed in neurons of the posterior root ganglion of slow loris (Nycticebus coucang) following administration of tricresylphosphate (TCP) 0.2 ml/kg body weight for 10 days. The observed changes involved the rough and smooth endoplasmic reticulum profiles, neurofilaments, Golgi complex as well as lipofuscin pigment. Nissl substance was markedly...

BACKGROUND The epidemic form of Bovine Spongiform Encephalopathy (BSE) is generally considered to have been caused by a single prion strain but at least two strain variants of cattle prion disorders have recently been recognized. An additional neurodegenerative condition, idiopathic brainstem neuronal chromatolysis and hippocampal sclerosis (IBNC), a rare neurological disease of adult cattle, w...

BACKGROUND The present study describes the pathologic changes in the brain and the spinal cord of aborted, stillbirth and deformities of newborn lambs infected with viral agents. METHODS From February 2012 to March 2013, a total of 650 aborted fetuses from 793 pregnant ewes were studied from 8 flocks at different areas in the Mazandaran province in the north of Iran.

During recent years, particularly since anatomical and physiological experimental methods have failed to provide evidence that the hippocampus has a direct relationship to olfaction (Rose and Woolsey, 1943; Fox, McKinley, and Magoun, 1944; Le Gros Clark and Meyer, 1947; Meyer and Allison, 1949), increasing attention has been focused on this cortical structure. Its functional significance remain...

BACKGROUND Equine motor neuron disease (EMND) is a neuromuscular disorder that affects adult horses. Although EMND has been linked to vitamin E deficiency, its etiopathogenesis is poorly understood. OBJECTIVES To describe clinical features, laboratory results, and postmortem findings in a series of young horses with motor neuron disease (MND). ANIMALS A herd of 15 young Andalusian horses wi...

However, over consumption of herbal medicines has led to many unpredictable side effects.One of these traditional medicines is Citrullus colocynthis, which is used by diabetic patients as an hypoglycemic agent, but it has been reported to cause gastroi...

The objective of this study was to assess the effect of monosodium glutamate (MSG) on broiler performance, blood chemistry and the brain tissues. A total of 120 day-old Lohman broiler chicks were randomly divided into four groups, with 3 replicates (30 birds per treatment). Four approximately isonitrogenous and isocaloric diets with different levels of MSG viz . 0, 0.25, 0.5 and 1.0% were formu...
