Recall of Prior Knowledge in Medical Microbiology Among Medical Interns: A Multicenter Cross-Sectional Assessment in Saudi Arabia.

Background: Retention of basic biomedical sciences knowledge is of great importance in medical practice. This study aimed to provide some insights into medical interns' ability to recall theoretical knowledge of medical microbiology and to explore factors that affect its retention.

Methods: In this cross-sectional study conducted between January and March 2019, an anonymized questionnaire with 10 validated multiple-choice questions about medical microbiology was distributed as hard copies to test the ability to recall knowledge of Saudi medical interns in three tertiary training hospitals in Riyadh, Saudi Arabia.

Broad beans () and the potential to protect from COVID-19 coronavirus infection.

Due to its high linoleic acid concentration (41%), sesame oil has been proposed to have the potential to protect from COVID-19 coronavirus (SARS-CoV-2) infection, which was characterised by the World Health Organization as a pandemic in March 2020. Unsaturated fatty acids, in general, are active against some enveloped viruses, like COVID-19 coronavirus, due to the incorporation of the fatty acid into the lipid membrane of the viral envelope causing destabilisation of its bilayer. Broad beans (), grown in Northern Sudan, proved to incorporate high content of unsaturated fatty acids and in particular linoleic acid (46.

Prevalence and associated factors of cigarette smoking among medical students at King Fahad Medical City in Riyadh of Saudi Arabia.

Objective: To determine the prevalence of smoking among medical students at the medical college at King Fahad Medical City in Riyadh, and assess the association between smoking and socio-demographical factors, smoking contacts, reasons for smoking and attempts to quit.

Materials And Methods: Cross-sectional survey in which anonymous, self-administered questionnaire was used to survey the cigarette smoking habits of the first- and second-year medical students in the Faculty of Medicine, King Fahad Medical City in June 2009.

Results: Overall 39.

A substance in broad beans (Vicia faba) is protective against experimentally induced convulsions in mice.

Vicia faba (VF, broad beans) constitutes a major food item for the River Nile populations. Contrary to tropical Africa, the prevalence rate of epilepsy (0.9-1 per 1000) among schoolchildren of Khartoum Province, Sudan, is lower compared with the rates in Europe and North America.

Pharmacokinetic interaction of ketoconazole and itraconazole with ciprofloxacin.

The effect of the concomitant administration of the antifungal drugs ketoconazole (KTC) and itraconazole (ITC) on the pharmacokinetics of ciprofloxacin (CIP) following short- and long-term administration in mice was investigated. Animals received either a dose of CIP (20 mg/kg, i.p.

Effects of zafirlukast on the function of humanpolymorphonuclear neutrophil leukocytes in asthmatic patients: A prospective, controlled, in vitro study.

Background: Reactive oxygen species (ROSS) play an important role in the pathogenesis of asthma, and oxidative stress contributes to the initiation and worsening of inflammatory respiratory disorders (eg, asthma). Thus, antioxidant drugs may have a role in reducing or preventing damage in asthma.

Objective: The aim of the study was to investigate the antioxidant effect of zafirlukast, a leukotriene receptor antagonist, in asthma.

Effect of diclofenac alone or in combination with alpha-tocopherol on the oxidative activity of polymorphonuclear leukocytes in healthy and osteoarthritic individuals.

Objective: To investigate the effects of diclofenac alone or when combined with alpha-tocopherol on the oxidative activity of polymorphonuclear leukocytes (PMNs) in healthy and osteoarthritic (OA) patients.

Methods: The study was carried out at the College of Medicine, King Saud University, Riyadh, Kingdom of Saudi Arabia, over the period 1999 to 2000. Twelve healthy controls and 12 osteoarthritic patients were recruited to the study.

Interaction of allopurinol and non-steroidal anti-inflammatory drugs on the carrageenan-induced rat paw edema.

Objective: To find out the effect of combining allopurinol with non-steroidal anti-inflammatory drugs on carrageenan-induced rat paw edema.

Methods: The study was carried out at the College of Medicine, King Saud University, Riyadh, Kingdom of Saudi Arabia, over the period 1999 to 2000. Male wistar rats were randomly divided into 12-16 rats in each group.

Evaluating the prophylactic potential of zafirlukast against the toxic effects of acetic acid on the rat colon.

The present work was conducted to assess the possible protective effects of zafirlukast against the toxic damage induced by acetic acid in rat colon. Zafirlukast is a potent and selective cysteinyl leukotriene receptor antagonist which is used mainly in the prophylaxis of bronchial asthma. Two doses of zafirlukast were used (40 and 80 mg/kg) dissolved in gum acacia and given either orally or rectally (0.
