About faculty of Medicine

The Faculty of Medicine was established in 1973, Tripoli, to contribute in qualifying medical personnel. The Faculty graduated its first batch in 1980.

 

It is one of the largest faculties at the University of Tripoli. It an important edifice of knowledge, so that during the past four decades this Faculty has contributed to preparing and graduating qualified doctors who had been very successful in performing their assigned role in the medical field in all the hospitals located all over the country. The graduate doctors were able to provide the best health services. The Faculty of Medicine has more than 493 faculty members, most of them are national elements who were among the first batches in this college and who contributed to providing the necessary health services in hospitals, clinics and dispensaries.

 

Many graduates of this Faculty have been sent to complete their studies abroad and who have proven their capabilities in scientific and clinical achievement with the testimony of many international universities. The Faculty seeks to activate graduate programs in various disciplines. It works to develop the vocabulary of its curricula and teaching methods that keep pace with the requirements of international quality.

Mode of Cell Death in Mouse Brain Following Early Exposure to Low-Dose Trichloroethane: Apoptosis or Necrosis

The goal of this study was to investigate, in-vivo, the predominant mechanism of cell death, apoptosis versus necrosis, in the mature mouse brain exposed early to a ubiquitous environmental toxicant trichloroethane (TCE). A subset of male albino mice was injected intraperitoneally twice weekly for three weeks with TCE (100 and 400µg/kg). All animals were followed up for signs of toxicity and mortality. Changes in neural tissues were histpathologically evaluated. Biomarkers of brain cell number were also studied. The results showed that TCE insult triggered significant alterations in the microstructure of the brain tissues compared to controls. Mitotic figures and apoptotic changes such as chromatin condensation and nuclear fragments were also identified. Cell death analysis demonstrates that cell apoptosis with necrosis was evident in the TCE-treated groups. The percent of necrosis was quantified as 20.09 ± 2.57% at 100µg/kg TCE, 30.57 ± 5.18% at 400µg/kg TCE, and 12.67 ± 1.25% in controls. However, the percent of apoptosis was quantified as 29.18 ± 1.51% at 100µg/kg TCE, 20.14 ± 2.12% at 400µg/kg TCE, and 8 ± 1.25% in controls. There was also a significant reduction in the brain DNA content in the TCE-treated groups. Agarose gel electrophoresis is also provided further biochemical evidence of apoptosis by showing internucleosomal DNA fragmentation. These results correlated with neurobehavioral impairment. These findings indicate that TCE induces degeneration and apoptotic cell death in mouse brain, suggesting a crucial role played by apoptosis in TCE neurotoxicity.

Cellular and molecular etiology of hepatocyte injury in a murine model of environmentally induced liver abnormality

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.

Oxidative Stress Mediated Cytotoxicity of Trichloroethane in a Model of Murine Splenic Injury

The present in vivo murine study was aimed to investigate the long-term effect of repeated administration of low-dose of the environmental toxicant trichloroethane (TCE) over three weeks on the spleen and peripheral blood cells, and the possible role of oxidative stress in TCE-induced toxicity. The results showed neither adverse clinical signs nor mortality on the TCE-treated mice. However, significant changes were noticed in the spleen of those animals. Grossly, the spleen of TCE-treated group was congested and enlarged (splenomegaly). Histpathologically, the splenic tissues of TCE-treated mice showed signs of toxicity as highly activated germinal centers of the white pulp with minimal apoptotic reaction as well as a prominent megakarocytosis and infiltration of the red pulp by comparatively increased number of eosinophiIs and mature lymphocytes were detected. In addition, lymphocyte numbers were decreased in peripheral blood as well as basophils. In contrast, there was an increase in monocyte numbers in the peripheral circulation. In addition, lipid peroxidation/ malondialdehyde formation, a biomarker of oxidative stress, was significantly induced by TCE treatment in the sera and spleen of mice, suggesting an overall increase in oxidative stress. These results provide further support to a role of oxidative stress in TCE-induced cell death, which could result in an impaired spleen function. This study concludes that attenuation of TCE-induced splenic damage in mice provides an approach for preventive and/or therapeutic strategies
