In vivo and In vitro Comparative Evaluation of the Antidiabetic Potentials of the Parts of Moringa oleifera Tree

http://www.biosciencejournals.com/archives/2016/vol4/issue1/3-12-29
 This study comparatively evaluated the in vivo and in vitro antidiabetic potentials of ethanol extracts of Moringa oleifera seed, stem, flowers, leaves and roots. In the in vivo study, diabetes was induced in rats by intraperitoneal injection of 150 mg alloxan/ kg body weight. Graded doses (100, 200, 400 and 800 mg/ kg) of each extract were administered to different sets of diabetic rats and their blood glucose levels monitored at 1, 2, 3, and 6 hr post- treatment. The percentage glycaemic reduction at each hour by each dose level was calculated. In the in vitro studies, different concentrations of each extract were subjected to α-amylase and α-glucosidase inhibitory assays and the percentage inhibition produced estimated. Results showed that the seed followed by the leaves extracts produced more glucose lowering/ enzyme inhibition activities. It was concluded that the leaves and seed of M. oleifera possess more anti-diabetic activity than its root, stem and flowers. Please follow the link provided above to read the complete article.

Animals can become infected with these parasites when grazing in pastures or drinking contaminated water. Eating undercooked meat from infected animals is the main cause of tapeworm infection in people. Although tapeworms in humans usually cause few symptoms and are easily treated, they can sometimes cause serious, life-threatening problems. That's why it's important to recognize the symptoms and know how to protect yourself and your family. Tapeworm Causes Six types of tapeworms are known to infect people. They are usually identified by the animals they come from -- for example, Taenia saginata from beef, Taenia solium from pork, and Diphyllobothrium latum from fish. Tapeworms have a three-stage lifecycle: egg, an immature stage called a larva, and an adult stage at which the worm can produce more eggs. Bec

The 40th convocation ceremony of the Ahmadu Bello University (ABU), Zaria will hold tomorrow with 8,260 students graduating with first degrees. The Vice Chancellor of the university, Professor Ibrahim Garba, made this known during a press briefing yesterday, saying that the convocation would confirm the graduation of 256 PhD students. He said the number of PhD and about 3,600 other postgraduate graduands was a confirmation of the new status that ABU had assumed where priority was given to postgraduate studies. Professor Garba said ABU was expanding its carrying capacity through introduction of new programmes to accommodate more applicants who usually overwhelmed the school. “It is in this direction that we now allow more institutions to run degree programmes with our affiliation.  We have also introduced distance learning where we admit hundreds of students and we would commence undergraduate studies in the centre,” he said.
