Lemongrass Leaf Extract Attenuates Hydrocarbon- Induced Oxidative Stress and Macrocytic Hypochromic Anaemia in Rats | Chapter 09 | Emerging Research in Medical Sciences Vol. 1

Aim: The therapeutic use of medicinal plants and plant products to mitigate solvent/xenobiotic-induced haematological disorders has not been adequately explored. The aim of this study was to evaluate the effect of Cymbopogon citratus (C. citratus) leaf decoctions on gasoline vapour (GV)-induced haematological disorders and oxidative stress in rats.

Methodology: Seventy-two female rats weighing 180-200g were randomly selected and divided into six groups (n = 12 per group). Animals in group 1 served as unexposed controls, while animals in group 2 were exposed to gasoline vapour (GV) alone for 35 days. Animals in groups 3, 4 and 5 were exposed to GV and co-administered C. citratus leaf extract (500 mg/kg, 1000 mg/kg, and 1500 mg/kg, respectively) and animals in group 6 were exposed to GV and co-administered vitamin C (200 mg/kg) for the same time period.

Results: Exposure of animals to GV alone significantly (p < 0.05) decreased packed cell volume (PCV), haemoglobin concentration (HB), total red blood cells (RBC), mean cell haemoglobin (MCH) and mean cell haemoglobin concentration (MCHC). Total white blood cells (WBC), WBC lineages and malondialdehyde (MDA) levels significantly increased (p < 0.05) compared to the corresponding values in the control group. Supplementation with C. citratus leaf decoction and vitamin C reversed these GV-induced changes in haematological indices and MDA levels.

Conclusion: Therefore, C. citratus leaf decoctions and vitamin C supplementation provided an ameliorative effect on GV-induced haematotoxicity and oxidative stress in a rat model of gasoline exposure.

Consensus Summit: Lipids and Cardiovascular Health in the Nigerian Population | Chapter 09 | Current Trends in Food Science Vol. 1

Aims: To issue a consensus statement on Lipids and Cardiovascular Health and the impact of their interrelationship in Nigerian Population. Study Design: Experts from a range of relevant disciplines, deliberated on different aspects of Lipids and Cardiovascular Health in the Nigerian Population at a Summit. Place and Duration of Study: The Summit was held in April 2016 at the Nigerian Institute of Medical Research. Methodology: Presentations were made on central themes after which expert participants split into four different groups to consider the questions relevant to different sub themes of the title. Consensus was arrived at, from presentations of groups at plenary. Conclusion: With the increase in the prevalence of NCDs, especially Cardiovascular Disease in Nigeria, and the documented evidence of deleterious effects of lipids, the expert panel called for an urgent need to advocate for the general public and health professionals to make heart-friendly

A Review on Gongronema latifolium, an Extremely Useful Plant with Great Prospects | Chapter 11 | Recent Advances in Biological Research Vol. 3

Gongronema latifolium is a plant that has a wide range of nutritional and ethnomedical uses in different tropical African communities. Scientific reports on the chemical composition and bioactivity (anti-inflammatory, antimicrobial, antidiabetic, antioxidant, anticancer and allelopathic properties) of the plant material by different authors are discussed in this review. Future prospects of the plant extracts in the areas of herbal formulations, food preservation, alcoholic fermentation and beer production, drug discovery and allelopathy are also highlighted.

An Overview of Ultrasonic Technology and Its Applications in Food Processing, Preservation and Quality Control | Chapter 03 | Current Research in Science and Technology Vol. 3

Ultrasound is one of the emerging technologies that were developed to minimize processing, maximize quality and ensure the safety of food products. In recent years, ultrasound technology has been used as an alternative processing option to conventional thermal approaches. Although Ultrasonication methods have been used for years in research and diagnostics, major advances have been made in the last decade. The applications for which high power ultrasound can be used range from existing processes that are enhanced by the retrofitting of high power ultrasonic technology, to the development of processes up to now not possible with conventional energy sources. The present paper reviews the generation, principle mechanism, properties, process parameters, applications, merits and demerits and future trends of the ultrasound technology in the food processing.
