Ethnobotany And Traditional Management Of Drought Tolerant Tree Species In Homestead Forests Of Bangladesh, Mahbubul Alam, Yasushi Furukawa

Ethnobotanical Leaflets

A study has been conducted in the homesteads of drought-prone northwestern region of Bangladesh. Since there is no natural forest, the overall climatic condition is very harsh and progressive trend of desertification is threatening the livelihood of poor people. So it is important to carry out extensive plantations throughout the region to reverse the current trend of drought and desertification. The study identified a list of 19 drought tolerant species suitable for planting in the homesteads as well as in the vacant spaces. The rural people are heavily dependent on those species for their daily requirement of timber, fruits, fuel, …

Anti-Hyperglycaemic And Insulin Release Effects Of Coccinia Grandis (L.) Voigt Leaves In Normal And Alloxan Diabetic Rats, Asirvatham Doss, Rangasamy Dhanabalan

Ethnobotanical Leaflets

Coccinia grandis (L.) Voigt (Cucurbitaceae), occurs throughout the world and has intensive popular use in the treatment of infections. The main aim of the present work was to investigate the antidiabetic effects of aqueous extracts of leaves of C. grandis obtained by Decoction method. Graded doses of the aqueous extract were administered to normal and experimental diabetic rats for 10 days. Significant (p < 0.05) reduction in fasting blood glucose levels were observed in the normal as well as in the treated diabetic animals. Serum insulin levels were not stimulated in the animals treated with the extract. The changes in body weight, serum lipid profiles, liver glycogen levels were assessed in the extract treated diabetic rats and compared with diabetic control and normal animals.

Plant Community Diversity And Composition Provide Little Resistance To Juniperus Encroachment, Amy C. Ganguli, David M. Engle, Paul M. Mayer, Eric C. Hellgren

Publications

Widespread encroachment of the fire-intolerant species Juniperus virginiana L. into North American grasslands and savannahs where fire has largely been removed has prompted the need to identify mechanisms driving J. virginiana encroachment. We tested whether encroachment success of J. virginiana is related to plant species diversity and composition across three plant communities. We predicted J. virginiana encroachment success would (i) decrease with increasing diversity, and (ii) J. virginiana encroachment success would be unrelated to species composition. We simulated encroachment by planting J. virginiana seedlings in tallgrass prairie, old-field grassland, and upland oak forest. We used J. virginiana survival and growth …

Ethnobotanical Leaflets

India has a rich heritage of using medicinal plants for indigenous uses and practices. Some of the country's best herbal medicines have also been introduced worldwide, and new applications have been found for them in different parts of the world. This new found "fame", however, has proven to be troublesome for India in some instances. For example, the “turmeric case” highlights the problems faced by this country in preventing bio-piracy. Traditional systems of medicine such as Ayurveda, Sidda, Unani, and homeopathy make use of more than 2000 plant species. Local People, medicinal practitioners and tribal healers of this country where …

Spatial And Temporal Analysis Of Contact Rates In Female White-Tailed Deer, Lene J. Kjaer, Eric M. Schauber, Clayton K. Nielsen Nov 2008

Spatial And Temporal Analysis Of Contact Rates In Female White-Tailed Deer, Lene J. Kjaer, Eric M. Schauber, Clayton K. Nielsen

Publications

White-tailed deer (Odocoileus virginianus) are important game mammals and potential reservoirs of diseases of domestic livestock; thus, diseases of deer are of great concern to wildlife managers. Contact, either direct or indirect, is necessary for disease transmission, but we know little about the ecological contexts that promote intrasexual contact among deer. Using pair-wise direct contacts estimated from Global Positioning System collar locations and joint utilization distributions (JUDs), we assessed habitats in which contacts occur to test whether direct contact rates among female white-tailed deer in different social groups differs among land-cover types. We also tested whether contact rates …

Review Of Ethnomedicinal Uses And Pharmacology Of Evolvulus Alsinoides Linn., Amritpal Singh Oct 2008

Review Of Ethnomedicinal Uses And Pharmacology Of Evolvulus Alsinoides Linn., Amritpal Singh

Ethnobotanical Leaflets

Evolvulus alsinoides L. (Convolvulaceae) is used as nootropic or brain-tonic in traditional systems of medicine like Ayurveda and Unani. The plant is used by certain ethnic races across India, Africa and Philippines to cure fever, cough and cold, venereal diseases, azoospermia, adenitis, and depression. Pre-clinical (in vivo and vitro) investigations have demonstrated anti-amnesic, antistress (adaptogenic), antimicrobial and gastro protective activity. Although clinical-studies are warranted for potential use of E. alsinoides in treating dementia, pre-clinical research has justified the ancient claim of ‘brain-tonic.' The review summarizes ethno medicinal uses and pharmacological investigations carried on the medicinal plant.

Ethnobotanical Leaflets

Over the past decade plants have become an interesting source of new classes of pharmacologically active natural products. Some secondary metabolites are also well known for their effectiveness on living species. The PASS (Prediction of Activity Spectra for Substances) computer program, which is able to simultaneously predict more than one thousand biological and toxicological activities from only the structural formulas of the chemicals, was used to predict the biological activity profile of 7 secondary metabolites. PASS predictions were successfully compared to the available information on the pharmacological and toxicological activity of these compounds.
