Consumption of green tea (Camellia sinensis)

ABSTRACT Consumption of green tea (Camellia sinensis) may provide protection against chronic diseases, including cancer. Green tea polyphenols are believed to be responsible for this cancer preventive effect, and the antioxidant activity of the green tea polyphenols has been implicated as a potential mechanism. This hypothesis has been difficult to study in vivo due to metabolism of these compounds and poor understanding of the redox environment in vivo. Green tea polyphenols can be...

Antioxidant Defense System in a Germinating P.Vulgaris

Phaseolus vulgaris, Common Bean is a herbaceous annual plant grown worldwide for its edible dry seed (known as just "beans") or unripe fruit (green beans) and a member of the legume family Fabaceae.  They are quite popular amongst the natives because of its high protein, minerals and vitamins content (Gentry et al., 1999).The use of a wide range of chemicals to destroy pests and weeds is an important aspect of agricultural practice in both developed and developing countries but there is a wi...

Antioxidant Property of Coconut (Cocos nucifera) Water

ABSTRACTCoconut water is a natural nutritious beverage that contains several biologically active compounds. This study was set up to evaluate the antioxidant potential of coconut water. Twenty five adult male albino rats, used in this work, were grouped into five (A, B, C, D and E), of five rats per group. Groups A, B, C and D were administered orally with 0.5, 1.0, 1.5 and 2.0mg/kg body weight respectively of the coconut water for seven consecutive days. Group E was the control. Giutathione ...

COMPARATIVE ANALYSIS OF HEAVY METALS IN BRASSICA OLERACEA FROM KENYATTA MARKET, NAIROBI AND KAGOCHI, KARATINA

ABSTRACTVegetables has been an integral part of day to day diet for so many people in Kenya. It is used in the form of raw fruits, dried, powdered or cooked vegetables. This is a research that addresses this way of living to act as a precaution towards making the food healthier. It is with a significant concentration in Kenyatta market than Kagochi while chromium’s level was higher in Kagochi compared to Kenyatta market.From the above figures of heavy metals, it was conc...

The potential protective effects of Diphenyl-diselenide (PhSe)2 on Mercuric chloride-Induced Nephrotoxicity in female wistar rats

ABSTRACT Evidences have implicated free radicals or reactive oxygen species in mercuric chloride-induced nephrotoxicity. Diphenyl diselenide (PhSe)2, a simple and stable organoselenium compound, has been proposed as a good candidate for pharmacological and therapeutic purposes. This particular study was designed to investigate the protective effect of (PhSe)2 against mercuric chloride-induced nephrotoxicity. In this study, 44 female Wistar rats with weights ranging from 125g and 180g were r...

ACTIVATION OF CASPASE ACTIVITY IN RAT LIVER CELLS BY METHANOL EXTRACT OF GLORIOSA SUPERBA

Activation of caspase 3&9 by methanol extract of Gloriosa superba ABSTRACTMitochondrion is the key regulator in cellular energy homeostasis and plays a central role in determining cell apoptotic process; it is therefore regarded as a vital target for cancer chemotherapy. Cancer is obviously one of the most common areas where demand for alternative treatment is overwhelming. Many investigations revealed that bioactive compounds in natural products can act on mitochondria to trigger the perme...

Caspase activation by methanol extract of Gloriosa superba on rat liver cells

Methanol extract of Gloriosa superba in this research was adopted due to the presence of photochemicals present in the plant. This photochemicals are known to act as antioxidants and anti tumor agent but it is not yet known if the activity of the plant is through the mitochondria mediated pathway, caspase activation and induction of apoptosis where up regulation is necessary 

ANTIBIOTIC SUSCEPTIBILITY OF Staphylococcus aureus IN CATTLE

ABSTRACT        This work was done to determine the antibiotic susceptibility of Staphylococcus aureus among cattle in Owerri, Imo State. A total of twenty four (24) samples were collected which were cultured on appropriate bacteriological media. The Staphylococcus aureus isolates were identified by standard biochemical tests. Antibiotic susceptibility profile of the isolates was performed according to Clinical and Laboratory Standard Institute (CLS...

The results showed the presence of sodium (Na), potassium ...

Student industrial work experience report at Nigerian Bottling Company, Asejire

 ABSTRACTThe students industrial work experience scheme (SIWES) is a skill impacting program designed to expose and prepare students of universities and other tertiary institutions for the industrial work situation that may be encountered after school. My SIWES program was undertaken at Nigeria Bottling Company limited, Asejire plant, Ibadan; a company that deals with the manufacturing of non-alcoholic beverage products such as Coca-Cola, limca, Fanta orange etc. The company has vario...

Comparative biochemical effect ofoleanolic acid and rutin on acute kidney injury in wistar rats

ABSTRACTThe inability of an organism to efficiently remove excess waste from the body have been a major issues attached to acute kidney injury (AKI) which is the most common cause of organ dysfunction. Oleanolic acid and rutin which are from the families of saponin and flavonoid respectively have been discovered to possess certain biological activities such as anti-oxidant, anti-inflammation, anti-viral and nephroprotective activities that can help in therapeutic management of acute k...

COMPARATIVE STUDY ON THE PHYTOCHEMICAL ANALYSES, ANTIOXIDANT ACTIVITIES AND PROXIMATE ANALYSES OF NESCAFE CAFFEINATED, DECAFFEINATED AND LIVEN ALKALINE COFFEE

ABSTRACTThe consumption of the popular beverage coffee, increases day by day. However, upcoming brands of coffee with health benefits made by claims of the product ignites curiosity in the components of the coffee. The current study deals with the phytochemical analysis, antioxidant capacity and proximate analysis of Liven Alkaline Coffee, Nescafe Caffeinated and Nescafe Decaffeinated coffee performed using standard procedures. The phytochemical analysis revealed higher contents of carbohydra...
