Changes of hematological and biochemical parameters and levels of pepsinogen, histamine and prostaglandins in dairy cows affected with left displacement of the abomasum.

The aims of this study were to determine the serum levels of pepsinogen, histamine, and prostaglandins F2α and E2 in lactating dairy cows affected with left displacement of the abomasum (LDA). In addition, the hematological and serum biochemical parameters were also determined in cows affected with LDA. A total of 52 adult lactating Holstein-Friesian cows affected with LDA and 30 normal cows (control) were used.

Clinico-pathological evidence that axonal loss underlies disability in progressive multiple sclerosis.

Growing evidence suggests that axonal degeneration rather than demyelination is the pathological substrate underlying chronic, irreversible disability in multiple sclerosis. However, direct evidence linking clinical disability measured in vivo with corresponding post-mortem measures of axonal pathology is lacking. Our objective in this study was to investigate the relationship between motor disability accumulated by patients with multiple sclerosis during life and the degree of axonal loss observed in their descending motor tracts after death.

Greater loss of axons in primary progressive multiple sclerosis plaques compared to secondary progressive disease.

The pathological substrate of progressive disability in multiple sclerosis is hypothesized to be axonal loss. Differences in the demographic, pathological and radiological features of patients with primary progressive compared with secondary progressive multiple sclerosis raise the question as to whether they actually represent separate clinical entities. So far, large pathological studies comparing axonal damage between primary progressive and secondary progressive multiple sclerosis have not been reported.

Metabolic profiles in goat does in late pregnancy with and without subclinical pregnancy toxemia.

Background: Pregnant goat does can develop various metabolic diseases during late pregnancy that may have profound effects on their health and productivity, including subclinical pregnancy toxemia.

Objectives: This study was performed to evaluate serum biochemical findings in goats in late pregnancy with and without subclinical pregnancy toxemia.

Methods: Serum samples were obtained from 153 clinically healthy goats in the last trimester of pregnancy from 14 herds in central and northern Jordan.

Risk factors associated with camel brucellosis in Jordan.

During the period between February, 2004 and December, 2006, a cross-sectional study was performed to investigate some epidemiological aspects related to camel brucellosis in Jordan. Four hundred twelve camel sera from 37 herds were randomly collected and analyzed using Rose Bengal plate test and complement fixation test. A structured pre-tested questionnaire was administered to collect information on camel herd health and management.
