Sodium metabisulfite (SMB) is a biocide and antioxidant agent generally used as a preservative in food and beverage industries but can oxidize to harmful sulfite radicals. A standardized (EGb-761) has demonstrated potent antioxidant and anti-inflammatory activities, which is beneficial for the treatment of diseases that exhibit oxidative stress and inflammation. The present study sought to investigate the putative ameliorative effects of EGb-761 against SMB-induced toxicity in mice.

Purpose: Crime-related spiking of alcoholic drinks with prescription drugs is quite common and has been happening for centuries. This study, therefore, evaluated the effects of oral administration of alcohol spiked with the zolpidem and midazolam potent sedatives on inflammation, oxidative stress and various organ damage in male Swiss albino mice.

Methods: Mice were randomly assigned into six treatment groups; the first group constituted the normal control, the second group received 50 mg/kg body weight of zolpidem only, the third group received 50 mg/kg body weight zolpidem dissolved in 5 g/kg alcohol, the fourth group received 50 mg/kg midazolam only, the fifth group received midazolam (50 mg/kg) dissolved in 5 g/kg alcohol and the sixth group received 5 g/kg alcohol.

Background: While sustainability has become a universal precept in the development of global health security systems, supporting policies often lack mechanisms to drive policies into regular practice. 'On-paper' norms and regulations are to a great extent upheld by frontline workers who often lack the opportunity to communicate their first-hand experiences to decisionmakers; their role is an often overlooked, yet crucial, aspect of a sustainable global health security landscape. Initiatives and programs developing transdisciplinary professional skills support the increased bidirectional dialogue between these frontline workers and key policy- and decisionmakers which may sustainably narrow the gap between global health security policy design and implementation.

Ethnopharmacological Relevance: The consumption of khat ( Forsk) is on the rise despite the much publicized associated deleterious health effects. How chemicals present in khat, affect various physiological and biochemical processes requires further scrutiny. A clear understanding of these processes will provide an avenue for countering khat-driven negative effects using appropriate pharmacological and/or nutritional interventions.
