Objective: To compare the degree of ameliorative effects of Melatonin(MEL), Ursodeoxycholic acid(UDCA) and Balanites aegyptiaca(BA) against hepatotoxicity induced by MTX for one month. Methods: Eighty adult male rats(Sprague Dawely) weighing(190±10g), were randomly divided into eight equal groups: Control, MTX, MEL, BA, UDCA, MTX+MEL, MTX+BA, MTX+UDCA. Liver function biomarker enzymes, liver tissue oxidative stress parameters, together with total antioxidant capacity and tumor necrosis factor(TNF-α) were determined. Histopathological and immunohistochemistry examinations for TNF-α were also done. Results: MTX showed significant increase in alanine transaminase(ALT), aspartate transaminase(AST), alkaline phosphatase(ALP), gamma glutamyl transferase(GGT), total and direct bilirubin, as well as TNF-α levels, oxidized glutathione(GSSG), malodialdehyde(MDA) and nitric oxide(NO). whereas, total protein, albumin, total antioxidant capacity, reduced glutathione(GSH), glutathione peroxidase(GPx), glutathione reductase(GR), glutathione S-transferase(GST), superoxide dismutase(SOD) and catalase(CAT) levels were significantly decreased in MTX treated group. These alterations were improved by MEL and BA treatment, whereas no improvement was noticed in UDCA treatment. Conclusions: BA may be as promising as MEL in the hepatoprotection against MTX toxicity through their antioxidant and radical scavenging activities. In addition, it is not recommended to co-administer UDCA with MTX as it enhanced inflammation and damage to the liver.

Ghadames basin is one of the important groundwater basins in Libya. This basin covers an area of about 215,000 km2 in northwestern Libya. This groundwater basin consists of two major aquifer systems. The upper aquifer system mostly formed of carbonate rocks (Mizdah and Nalut formations). The lower aquifer system formed mostly of sandstone known as Kiklah formation. The two aquifer systems are separated by semi-confining layers known as Yefren marl. The lower aquifer system is considered as the main aquifer for water supply. The water resource (mostly from the lower aquifer system) in these systems is used for domestic, irrigation and fodder drinking. The domestic use of water is to supply water to the cities and towns in western part of the country and in the northern flanks of the basin, and plans to transport water to the coastal cities in northwestern part of the country. The existing total amount of extracted water is 132 Mm3/year, and about 20% of it used for domestic uses. The planned water extraction is 223.8 Mm3/year about 55% of it will be used for domestic uses. The hydrogeological situation for this basin has been studied in this study using data from previous hydrogeological exploration programs, evaluation of the data from the existing extraction and observation water wells, pumping tests data used to evaluate aquifers hydraulic parameters, and construction of hydrogeological cross-sections to know the aquifer systems geometry. Hydogeological computer model was constructed to evaluate the aquifer hydraulic parameters using the historical water extraction, and water levels and drawdowns. The model is then used to predict the future drawdown which has been found to be in the range 55 to 60 m after 50 years of extraction.

Objective The aim of our study was to assess the complications of hepatic fibrosis associated with bile duct ligation and the potential curative role of sepia ink extract in hepatic damage induced by bile duct ligation. Methods Rattus norvegicus rats were divided into 3 groups: Sham-operated group, model rats that underwent common bile duct ligation (BDL), and BDL rats treated orally with sepia ink extract (200 mg/kg body weight) for 7, 14, and 28 d after BDL. Results There was a significant reduction in hepatic enzymes, ALP, GGT, bilirubin levels, and oxidative stress in the BDL group after treatment with sepia ink extract. Collagen deposition reduced after sepia ink extract treatment as compared to BDL groups, suggesting that the liver was repaired. Histopathological examination of liver treated with sepia ink extract showed moderate degeneration in the hepatic architecture and mild degeneration in hepatocytes as compared to BDL groups. Conclusion Sepia ink extract provides a curative effect and an antioxidant capacity on BDL rats and could ameliorate the complications of liver cholestasis.

Background: Irritable Bowel Syndrome (IBS) is a common functional gastrointestinal disorder (FGID), characterized by abdominal pain or discomfort and alteration in bowel habits. Aim of the study: To determine the overall prevalence, prevalence of each type and risk factors of IBS among Northern Border University (NBU) students, Arar, Kingdom of Saudi Arabia. Material and methods: We use cross sectional, descriptive study with multistage cluster probability sample. Using Rome III criteria questionnaire of IBS;which is a self-administrated consists of ten questions assessing the current status of an apparently normal person. The questionnaire is administrated to Northern Border University students. Results: A total of 228 University students of them, 94 (41.2%) males and 134 (58.8%) females were included in the study. The overall prevalence of IBS according to Rome III criteria in northern border University was (32.5%). The disease prevalence was 33.6% in females and 30.9% in males. Among the study participants, the most common type of IBS was the mixed one 12.7%, followed by the constipation predominant type 10.5%, then the diarrhea pre-dominant type 5.7% while the least common was unsubtyped cases (3.5%). Statistically significant increase in prevalence of this disease was found among female students (60.8% vs. 39.2% in males) (p-value < 0.05), the students who experienced psychic stress and irritability (79.7%) (p-value < 0.05) and students who were obese (p-value < 0.001). Conclusion: The results of this study concluded the prevalence rate of 32.5% for IBS among the students studying in Northern Border University. Stress and high body mass index were significantly associated with IBS. In addition, this study concluded that IBS was not significantly associated with socio-demographic characteristics and smoking.
