Antigenic distribution, pathological changes, antibody response and serological detection in non-pregnant goats following experimental infection by Brucella melitensis.

This study describes the pathological changes, antibody response, isolation and distribution patterns following exposure of non-pregnant goats to live Brucella melitensis. Eighteen healthy adult female goats were divided into two equal groups. Group 1 was infected via conjunctival sac with 10  cfu/ml of B.

Pathological changes and bacteriological assessments in the urinary tract of pregnant goats experimentally infected with Brucella melitensis.

Background: This study was conducted to investigate the pathological changes and distribution of B. melitensis in the urinary tract of pregnant goats following acute experimental infection. Six Jamnapari crossbred does in their third trimester of pregnancy were randomly assigned into two groups; Group 1 was uninfected control and Group 2 was inoculated conjunctival with 0.

Subacute Oral Toxicity Assesment of Ethanol Extract of Leaves in Male Sprague Dawley Rats.

The term Butterfly tea refers to decoction of leaves which is widely consumed by cancer patients throughout Malaysia and has gained a huge popularity among Malaysians, not only cancer patients but also researchers to discover the real potential of this plant. Herein, the study is aimed at evaluating the possible toxicity in 28-day subacute oral toxicity of ethanolic extract in male Sprague Dawley rats. The 28-day subacute toxicity study was conducted to detect the no-observed adverse effect level (NOAEL).

The induction of aryl hydrocarbon receptor (AHR) in immune organs of developing chicks by polycyclic aromatic hydrocarbons.

Polycyclic aromatic hydrocarbons are pollutants which are persistent in nature. The aryl hydrocarbon receptor is a ligand-activated cytosolic transcription factor activated by xenobiotics. The objective was to isolate and identify AHR mRNA transcript in immune organs of developing chicks and to interpret the correlation between AHR induction and dose of PAHs.

DNA damage and adduct formation in immune organs of developing chicks by polycyclic aromatic hydrocarbons.

Polycyclic aromatic hydrocarbons (PAHs) are persistent pollutants and chemically a class of structurally similar chemical compounds characterized by the presence of fused aromatic rings. This research was undertaken to find out immunotoxic effects produced by pyrene, phenanthrene and fluoranthene. These chemicals were injected into developing chicks at three dose levels (0.
