Exposures to a wide variety of environmental substances are negatively associated with many biological cell systems both in humans and rodents. Trichloroethane (TCE), a ubiquitous environmental toxicant, is used in large quantities as a dissolvent, metal degreaser, chemical intermediate, and component of consumer products. This increases the likelihood of human exposure to these compounds through dermal, inhalation and oral routes. The present in vivo study was aimed to investigate the possible cellular and molecular etiology of liver abnormality induced by early exposure to TCE using a murine model. The results showed a significant increase in liver weight. Histopathological examination revealed a TCE-induced hepatotoxicity which appeared as heavily congested central vein and blood sinusoids as well as leukocytic infiltration. Mitotic figures and apoptotic changes such as chromatin condensation and nuclear fragments were also identified. Cell death analysis demonstrates hepatocellular apoptosis was evident in the treated mice compared to control. TCE was also found to induce oxidative stress as indicated by an increase in the levels of lipid peroxidation, an oxidative stress marker. There was also a significant decrease in the DNA content of the hepatocytes of the treated groups compared to control. Agarose gel electrophoresis also provided further biochemical evidence of apoptosis by showing internucleosomal DNA fragmentation in the liver cells, indicating oxidative stress as the cause of DNA damage. These results suggest the need for a complete risk assessment of any new chemical prior to its arrival into the consumer market.

Introduction: Chronic granulomatous disease (CGD) is a rare inherited primary immune deficiency disease with prevalence of 1 in 250,000 worldwide. It is caused by mutations in the genes that encode the NADPH oxidase enzyme components responsible for the production of super oxide and other free radicals. These mutations lead to the absence or decrease of the microbicidal activity of the phagocytic cells. arabic 10 English 72

Background and objectives: Allergic rhinitis is common association to asthma according to worldwide studies which showed that control of allergic rhinitis improves in turn asthma symptoms so we have conducted this study looking for the percent of allergic rhinitis in Libyan asthmatic children who were attending regular follow up in asthma clinic of Tripoli children hospital over period of one year (2008). Methods: This study was conducted by asking children’s parents using questionnaire composed of directly answered questions (yes or no) if their children got attacks of rhinorrhea, nasal itching and sneezing around certain times of the year (spring and autumn). Results: Conclusively we found that the incidence of allergic rhinitis in asthmatic Libyan children was 36.6%. Conclusion: allergic rhinitis is common with asthma, and it needs to be put in consideration in any asthma patient and treated accordingly. Cite this article: Elzigallai O, Alrabty H.
