    Effectof the Oral pf Some Soft Drinks on the Fasting Blood Glucose Level and Lipid Profile of Albino Rats
    (International Journal of Sciences, 2014-06) Goje, L. J.; Joshua, H.; Shuaibu, I.; Ghamba, P. E.; Mafulul, S. G.
    The study was carried out to discover the effects of the oral intake of some soft drinks (Fanta, Sprite, Fayrouz, Coca-cola and Schweppes) on blood glucose level and lipid profile of albino rats. The rats were grouped into 6 each containing 4 rats, and were allowed to fast for 12hrs, their fasting blood glucose was taken to know their pre treatment fasting blood glucose level. Group 1 was administered with normal saline, group 2 was given Fanta, group 3 was given Sprite, group 4 was given Schweppes, group 5 was given Fayrouz and group 6 was given Coca-cola. All the groups were administered with 3ml of the soft drink per 100g body weight twice a day respectively throughout the period of the research. The research lasted for 14 days. On the last day the rats were allowed to fast again for a period of 12hrs after which the fasting blood glucose level was determined; finally, the rats were sacrificed by cervical decapitation and the serum collected for the determination of lipid profile. There was statistical difference (p<0.05) in fasting blood glucose between the pre-treatment and post-treatment values. Group 2 (Fanta fed rats) and Group 6(Coca-cola fed rats) showed high level of glucose (p<0.05) compared to normal control, while the groups administered with Sprite, Schweppes and Fayrouz respectively showed no statistical difference in fasting blood glucose level when compared to the normal control. In the analysis of lipid profile, the group administered with Fanta exhibited high level of total cholesterol, low level of triglyceride and low density lipoprotein and normal level of high density lipoprotein. The group given Coca-cola showed low level of total cholesterol, triglyceride, high density lipoprotein and normal level of low density lipoprotein, while the group given Schweppes showed high level of total cholesterol, triglyceride, high density lipoprotein and low density lipoprotein. The group given Fayrouz showed high level of Cholesterol, low density lipoprotein and low level of Triglyceride and high density lipoprotein. Lastly, the group given Sprite showed no statistical difference in all these parameters when compared to the control group. Therefore, it was concluded that among the various soft drinks used in the present study, it was only Sprite soft drink that appeared not to be implicated as a predisposing factor to any of the diseases considered.

    The aim of this study was to characterize the physical and chemical properties of Artemisia annua, an anti-malarial plant grown in the Grass-field Regions of Cameroon. Samples have been collected from seven localities with same climatic conditions. The GC-MS analysis of the extracts from the samples showed the presence of artemisinin, scopoletin and 13 volatile compounds including α-pinene, β-pinene, camphene, 3-carene, α-terpinene, limonene, eucalyptol, artemisia ketone, copaene, camphor, caryophylene, menthol and α-terpineol. When compared with A. annua grow in other countries, the Grass-field Regions of Cameroon produce seen more concentrated in artemisinin (11.1 mg/kg) than those from temperate regions [Luxemburg (0.4 mg/kg), Germany (0.8 mg/kg) and Belgium (1.1 mg/kg)] and similar to those from tropical countries [Brazil (11.5 mg/kg) and Democratic Republic of Congo (10.3 mg/kg)]. This result also showed that A. annua from the Grass-field Regions of Cameroon is highly concentrated in scopoletin, artemisinin and several other volatile compounds. The local production of this plant in Cameroon will be a source of medicinal significance for malaria zones and developing countries to fight against this disease.
