Toxicity Studies of the Extracts of Parkia biglobosa Stem Bark in Rats | Chapter 8 | Modern Advances in Pharmaceutical Research Vol. 1

Extracts of Parkia biglobosa stem bark is used in Nigerian traditional medicine (NTM) to treat malaria, diarrhea and pains. To establish the toxicity profile of the medicine such parameters as the lethal dose (LD50) as well as effects on body functions and organs were evaluated in albino Wistar rats. The bioactive constituents of the water and methanol extracts were also evaluated as a link to toxicity. The LD50 was greater than 5000mg/kg per oral (p.o) for both extracts.  No significant (P< 0.05) changes in body weights and vital organs of treated animals. However, at 5000mg/kg of water extract, a significant  increase  in  relative  weight  of  the  kidneys  and  hyper -cholesterolemic  effects  were observed. The extract also elicited significant increase in blood glucose level. The kidneys and livers of animals treated with P. biglobosa water extract for 14 days revealed histopathological evidence of pathological lesions. The methanol extract did not show any changes in the levels of hepatic and hematological  parameters, histopathological evidence of  pathological lesions, and  serum level of urea, uric acid, bilirubin,  creatinine and total protein concentrations. Treatment elicited hypo -cholesterolemic effects and significant reduction in blood glucose level occurred in all the groups. The phytochemical screening revealed the presence of tannins, flavonoids, saponins, terpenes, cardiac glycosides, phenols  and reducing  sugars  in the  methanol extract,  the water  extract  showed the presence of similar constituents with the absence of flavonoids and cardiac glycosides. This study has shown the toxicity characteristics of the methanol and water extracts of the stem bark P. biglobosa in short time treatment with the extracts. This study has shown the diversity in toxicity as well as the chemical constituent of the stem barks of P. biglobosa in relation to the extraction solvent. However this study provides the basis for further study on the detailed toxic and pharmacological effects of the extracts of P. biglobosa stem bark and their active component(s).

Greening Regional Airports: A Vision for Carbon Neutral Infrastructure | Chapter 12 | Contemporary Perspective on Science, Technology and Research Vol. 3

 This study provides an overview of the energy demand of a regional airport, divided into individual time horizons. The electrification of aircraft systems raises the question of whether airports will be among the largest electricity consumers in our infrastructure in the future. Sustainability and especially emission reductions are significant challenges for airports that are currently being addressed. The Clean Sky 2 project GENESIS addresses the environmental sustainability of hybrid-electric 50-passenger aircraft systems in a life cycle perspective to support the development of a technology roadmap for the transition to sustainable and competitive electric aircraft systems. This article originates from the GENESIS research and describes various options for ground power supply at a regional airport. Potential solutions for airport infrastructure with a short (2030), medium (2040), and long (2050) time horizon are proposed. In addition to the environmental and conservation benefi...

Study on Processing Method Influences the Effect of Cassava (Manihot esculenta) Consumption on Blood Lipid Profile in Rats | Chapter 8 | Current Research and Development in Chemistry Vol.1

Cassava is consumed in many tropical countries and is fast becoming the major raw material of many diets, especially in the bakery, brewery and pharmaceutical industries. In a study to determine the effects of various formulations of Cassava feeds on blood lipid profile in rats. Forty adult Wistar rats weighing between 120 and 150 g were divided into 4 groups of 10 rats each. The rats were acclimatized for one week; fed with different formulations of Cassava feeds adlibitum, after which the rats were allotted into groups. Group 1 was fed on Garri; group 2 on Cassava flour; group 3 on Tapioca, and the control group (group 4) on normal chow. After 4 weeks, each animal was anaesthetized by exposure to chloroform vapour and blood samples collected by cardiac puncture. Group 1 diet (Garri) significantly increased HDL-cholesterol (HDL-C) concentration and significantly decreased LDL-cholesterol (LDL-C) concentration (p<0.05) compared with the control group. In Group 2 (Cassava flour), t...

Ethnopharmacological Survey among Traditional Medicine Practitioners in Abidjan (Côte d'Ivoire) for the Management of Pathologies such as Malaria, ENT Diseases, Diarrhea, Typhoid Fever and Anemia | Chapter 05 | New Horizons in Medicine and Medical Research Vol. 8

 Traditional Medicine Practitioners (TMPs) of Côte d'Ivoire are familiar with the therapeutic herbs. Medicinal plants have been shown to be useful in the treatment of common diseases such as malaria (KROA, 2004) and diabetes (N'GUESSAN et al, 2013) in several studies and scientific study. In the Abidjan District, the current policy is to integrate traditional medicine and pharmacopoeia into the national health system in order to improve population health coverage, particularly in the management of commonly encountered diseases such as malaria, ENT diseases, diarrhoea, typhoid fever, and anaemia. This research aims to increase the use of traditional medicine and pharmacopoeia in the national health system. Over the course of three months, fifty (50) PMTs in the District of Abidjan participated in this study. Plant therapists accounted for 30 of the 50 PMTs polled at the end of the study, or 60%. Traditional medicine centres use 61 types of medicinal plants from 36 famili...
