This paper studies the impact of the implementation of

extensive reading programme on the reading comprehension

and the development of other English language skills such as

speaking, spelling and writing of Libyan university students

studying EFL. 50 students studying English in the English

Department, Faculty of Arts, Al-jabal Algharbi University had

read a written materials of their choice, summarised their

main events and completed a self-completion questionnaire.

The findings of the questionnaire data analysis suggested that

the respondents had a positive attitude towards their selfreading,

learned some new words. These findings may encourage the

teachers of reading comprehension courses to implement

extensive reading programme to complement the intensive

reading programme which is practiced in classroom. Also,

reading materials are required to be available in the

educational institutions' libraries.found the information of the written texts useful and

 Cutaneous leishmaniasis (CL) is an endemic parasitic infection in the Mediterranean region, including Libya and 

its Al-jabal Al-gharbi province. We aimed at studying the occupational relevance as well as other epidemiological aspects 

of CL. We investigated 140 CL cases who attended at Gharyan outpatient polyclinic during a period of 6 months in 2009. 

CL infection was clinically diagnosed and confirmed by demonstration of Leishmania parasites on smears from lesions. 

Our findings showed that males were more affected than females (P=0.04), and people above 10-years were more af￾fected than younger ones (P=0.0001). A significant percent of CL cases belonged to Al-Kawasem subprovince 

(P=0.0001). Farm-related activities were the most frequent occupations among CL cases (P=0.04). In addition to farm 

workers, housewives and students are at risk groups since they are engaged at farm activities. Moreover, those who have 

occupations that require staying outdoors for a part of night, e.g., policemen, are also at risk. Compared to children, adult 

CL patients had multiple lesions (P=0.001) that were more prevalent in their upper and lower extremities than the face 

(P=0.0001). We conclude that CL is a major health problem in Al-jabal Al-gharbi province of Libya. The presence of ro￾dents and sandflies makes it a suitable environment for Leishmania to spread in an endemic epidemiological pattern. Be￾ing engaged in farming activities or outdoor occupations increases the risk of infection. Various clinical patterns of CL 

suggest the presence of more than 1 species of Leishmania at Al-jabal Al-gharbi province. We propose that the 2 species 

responsible for CL in this area are L. major and L. tropica. Further investigations to identify the leishmanial species re￾sponsible for CL at Al-jabal Al-gharbi together with adoption of preventive and control programs are needed.

African trypanosomes are capable of both pyrimidine biosynthesis and salvage of preformed pyrimidines from the host. However, uptake of pyrimidines in bloodstream form trypanosomes has not been investigated, making it difficult to judge the relative importance of salvage and synthesis or to design a pyrimidine-based chemotherapy. Detailed characterization of pyrimidine transport activities in bloodstream form Trypanosoma brucei brucei found that these cells express a high-affinity uracil transporter (designated TbU3) that is clearly distinct from the procyclic pyrimidine transporters. This transporter had low affinity for uridine and 2′deoxyuridine and was the sole pyrimidine transporter expressed in these cells. In addition, thymidine was taken up inefficiently through a P1-type nucleoside transporter. Of importance, the anticancer drug 5-fluorouracil was an excellent substrate for TbU3, and several 5-fluoropyrimidine analogs were investigated for uptake and trypanocidal activity; 5F-orotic acid, 5F-2′deoxyuridine displayed activity in the low micromolar range. The metabolism and mode of action of these analogs was determined using metabolomic assessments of T. brucei clonal lines adapted to high levels of these pyrimidine analogs, and of the sensitive parental strains. The analysis showed that 5-fluorouracil is incorporated into a large number of metabolites but likely exerts toxicity through incorporation into RNA. 5F-2′dUrd and 5F-2′dCtd are not incorporated into nucleic acids but act as prodrugs by inhibiting thymidylate synthase as 5F-dUMP. We present the most complete model of pyrimidine salvage in T. brucei to date, supported by genome-wide profiling of the predicted pyrimidine biosynthesis and conversion enzymes.
