The Preliminary phytochemical and antibacterial evaluation of crude pericarp extract of Hyphaene thebaica (doumpalm) was ascertained. The crude pericarp powder of the plant was extracted for phytochemical screening by reflux method. The phytochemical analysis of the extract revealed the presence of tannins, steroids, saponins, carbohydrates, flavonoids, terpenes and terpinoids in low and moderate concentrations. The crude pericarp extract of this plant exhibited activity on some gram positive and negative laboratory bacterial isolates such as Staphylococcus aureus, Streptococcus pyogenes, Salmonella typhi, Escherichia coli and Shigella dysenteriae and the rest of the organisms were resistant to the extract. The effect of Hyphaene thebaica aqueous pericarp extract on gram positive and negative laboratory isolates indicates broad spectrum antibacterial activity. Most of the bacterial isolates were sensitive to all the concentrations of the extract used in this research except salmonella typhi that showed resistance at the concentration of 200 mg / ml. The minimum inhibitory concentration for Staphylococcus aureus, Streptococcus pyogenes and Salmonella typhi is 25 mg / ml while that for Escherichia coli and Shigella dysenteriae is 50 mg / ml. All the laboratory isolates has a minimum bactericidal concentration of 50 mg / ml. This finding concludes that Hyphaene thebaica (doumpalm) pericarp extract have some important bioactive principles that can be used as a therapeutic agent in the inhibition of these pathogenic organisms that are incriminated in the causation of various disease in humans and animals.

The emergence of antibiotic-resistant organisms is a major public health concern, particularly in hospitals and other health care settings. Antibiotic-resistant organisms appear to be biologically fit and are capable of causing serious, life-threatening infections that are difficult to manage because treatment options are limited. This increase in the prevalence of drug-resistant pathogens is occurring at a time when the discovery and development of new anti-infective agents is slowing down dramatically and most of the new agents are synthetic relatives of the older ones. Consequently, there is concern that in the not-too-distant future, we may be faced with a growing number of potentially untreatable infections.

Turmeric (Curcuma longa) is a rhizomatous herbaceous perennial plant of the ginger family, Zingiberacea. It is native to tropical south Asia and needs temperature between 200C -300C (680F and 860F) and a considerable amount of annual rainfall to thrive. Its active ingredient is curcumin and it has a distinctly earthly, slightly bitter, slightly hot peppery flavor and a mustardy smell. In both in-vitro and animal studies, curcumin has shown anti-tumor, antioxidant, antiarthritic, antiamyloid, antiischaemic and anti-inflammatory properties.Ethanolic extract of Curcuma longarhizomewas investigated for toxicity and effect on blood glucose level in albino rats. Elemental and phytochemical screenings were done using standard laboratory procedures. Lorke’s method was used to evaluate the acute oral toxicity of the plantusing twelve rats. Administration of 2900 mg/kg maximum dose did not produce mortality or general signs of toxicity for 24 hours. The hypoglycaemic study was carried out using 20 rats divided into groups A, B, C, and D. Groups B, C and D were treated orally using 200mg, 400mg and 600mg/kg of the extract while group A received distilled water for 18 hrs. A drop of blood from the tail vein of the rats was applied to the test spot of one touch glucose meter for blood glucose determination. Data obtained were analyzed and expressed as Mean ± Standard Deviation. The phytochemical screening revealed the presence of carbohydrate, soluble starch, anthraquinone, cardiac glycosides, saponin glycosides, terpenoids and flavonoids. The elemental analysis revealed the presence of chlorine, potassium, sodium, sulphur, iron, calcium, magnesium, zinc, manganese, lead and copper. The median lethal dose of the plant was greater than 2900 mg/kg body weight. The ethanolic extract did not cause death or signs of toxicity in the rats but significantly ( p<0.01) decreased blood glucose. In conclusion, Curcuma longashowed a wide safety margin and significant hypoglycemic effect in rats.

Significant binding of chloroquine occurs in the liver, kidney and spleen (Taylor and Francis 1987).For a very short period of three days, ten male rats were exposed to chloroquine phosphate injection intraperitoneally /IP) for three days. The treated rats received 0.125ml/100g body weight of chloroquine phosphate injection intraperitoneally. Control rats received the same amount of normal saline intraperitoneally.Stereologically, the parameters measured for the liver was compared with controls. The estimated absolute volume V =Vv (structure) x v (ref) of the blood vessels of the fractions was determined and compared. In the liver chloroquine caused a reduction in theabsolute volume of the blood vessels when compared with controls.

Climate changes, consequently, global warming is real. Therefore there is need to evolve effective eco-forming system to mitigate it. First among all strategies is to identify the causes and to be able to mitigate is to have climate-smart intelligence (knowledge of vulnerability, coping, adaptation and attitudinal changes). As one of the major cause is deforestation for agriculture, urbanization and industrialization. Thus, this study was undertaken to assess the possibility of using pots to raised plants in order to combat climate changes. This study was conducted in the research garden of the Federal College of Education, Yola, Adamawa State of Nigeria from 1st June, 2013 to 31st August, 2014. Twenty (20) wooden nursery boxes measuring 1.50 x 1.50 feet were constructed. The bottom and the top were left opened to allowed contact with the soil and the top to permit irrigation. Twenty (20) same size of the box were made on the bare soil. The boxes were filled with soil and the bare soil areas were made into bed using same soil. Both experimental units were randomly placed at 5 x 5 metres with same area, watered and allowed to settle for 7 days and ten (10) seeds of Moringa oleifera were planted in each experimental unit. After plants emergence, plants were thin to three per unit and latter to one (1). During the period of the experiment, no agrochemical was applied but the units were sufficiently watered using water can. Data collected were analyzed using ANOVA and means compared using least significant difference (LSD) at P=0.05. Results showed that the degree of morphological appearances in both experimental units, plants of potted experiment are more desirable. Secondly, greater plant emergence, soil chemical properties and plant height were better in the potted experimental units compared to those of control units. Therefore, potted plants are hereby recommended for the raising and to grow plants in the study area to mitigate climate change, thus the global warming.

Experiments were conducted during the 2007 and 2008 rainy season (May –September) at the Teaching and Research Farm of the University of Ibadan, SouthWestern Nigeria, to evaluate the residual effect of Mineral and Organo-Mineral fertilizers on growth and yield of Maize using different methods of application. ACR.91 SWAN1 maize variety was used as the test crop. A randomized complete block design was used with 11 treatments namely: control (no fertilizer), 2 and 1 t/ha-urea amended and unammended compost (buried and surface of Grade A and B), 6.7 and3.4t/ha (buried and surface of Grade A and B), N.P.K (300kg/ha-l, buried and surface) and replicated three times. Data were analysed using ANOVA and the means were separated using Duncan multiple range test. Result showed that OMF B1(buried) at 6.7t/ha gave the best performance in all characters observed with grain yield of 5.60tha-l followed by OMFA1 (buried) with 5.32tha-l. The buried methods of OMFB1, OMFA1 and NPK gave 5.60t/ha, 5.32t/ha and 2.99t/ha when compared with surface methods that followed the same trend with 4.10//t/ha , 4.15t/ha-1 and 2.40t/ha grain yield respectively with full dose. Organo-mineral fertilizer grade B performed better than the grade A at full dose which produced yields of 3.93t/ha and 2.38t/ha while NPK gave 1.90t/ha respectively. Half dose followed the same trend as shown in the full doses of grade A and B. The use of organic unammended fertilizer (OMFB1) gave a better result in residual maize growth and yield parameters compared to that of the control which grain yield of (2.10t/ha). Residual nutrients of OMFB1 (buried) sustained maize plant growth and had yields, which were 62.5% higher than the control.
