Objective: To investigate the prophylactic efficacy of date palm fruit extract against doxorubicin-induced hepatotoxicity in Wistar albino rats. Methods: The rats were equally and randomly assigned to 6 groups: group 1 (untreated control), group 2 and 3 given daily oral administration of prophylactic aqueous extract of date palm fruit at 0.75 and 1.5 mg/kg body weight, respectively, and group 4, 5 and 6 intraperitoneally injected with doxorubicin at 15 mg/kg on day 30. Rats in group 5 and 6 received daily oral administration of aqueous extract of date palm fruit at 0.75 and 1.5 mg/kg body weight, respectively, for 30 d. The phytochemicals identified by GC-MS analysis were analyzed using in silico study. Antioxidant enzymes, liver enzymatic, biochemical parameters and histopathological analysis were determined to evaluate hepatoprotective activity of date extract. Results: Aqueous extract of date palm fruit significantly mitigated doxorubicin-induced changes in activities of liver enzymes, reduced reactive oxygen species levels, and suppressed lipid peroxidation and DNA damage. Moreover, aqueous extract of date palm fruit reduced doxorubicin-induced hepatic lesions. Molecular docking studies showed that most compounds of aqueous extract of date palm fruit identified via GC-MS had good interaction with proteins of human pregnane X receptor, oxygenase-1, and CYP2C9. Conclusions: The aqueous extract of date palm fruit mitigates doxorubicin-mediated DNA damage and hepatotoxicity, and restores normal liver function and may be a promising agent against the deleterious effects of doxorubicin.

Aims: Helicobacter pylori is a gastrointestinal bacterium that causes peptic ulcers and stomach cancer in nearly half of the world’s population. Many virulence factors influence the outcome of H. pylori related disorders. The purpose of this study was to see if there was a relationship between H. pylori virulence factors and histological and endoscopic findings in stomach biopsy specimens from Sudanese gastritis patients. Methodology and results: In the period between March 2018 and January 2020, a total of 290 gastric biopsies were taken from patients in Khartoum State hospitals. Histopathology and polymerase chain reaction (PCR) assays were performed on all specimens. Histological investigation revealed H. pylori in 103/290 (35.5%) samples, while PCR revealed H. pylori 16S rRNA positivity in 88/290 (30.3%) samples. Eighty-eight positive PCR specimens were subjected to PCR for genotypic detection of cagA, cagE, vacA, dupA and iceA1 genes. All of strains were vacA positive 100% (88/88) followed by dupA 50.0% (44/88), cagA 40.9% (36/88), cagE gene 38.6% (34/88) and iceA1 gene was detected in only 15.9% (14/88). The vacA s1/m1 68.2% (60/88) was the most prevalent vacA subtype. Conclusion, significance and impact of study Helicobacter pylori virulence genes were widespread and diversified in Sudanese gastritis patients. Helicobacter pylori cagA and iceA1 were significantly in association with gastric mucosa inflammation degree, whereas the dupA gene was found to be associated with the clinical outcomes.
