Abstract The microbiological and physico-chemical analysess of water samples obtained from the Orogodo River, Agbor, at point of industrial effluent discharge (Location 2) and at 100m before (Location 1) and 100m after (Location 3), were carried out using standard methods to determine the impact of the discharge on the water quality. While the temperature, conductivity, biological oxygen demand, and coliform counts increased from Stations 1 to 3 and pH, hardness, alkalinity and dissolved oxygen decrease from Stations 1 to 3, the solid (Total, suspended and dissolved) and nitrates increased from Station 1 to 2 and 3 and sulphate, which was equal for Station 1 and 2, decreased in Station 3. Most of the parameters were above set limits by regulatory bodies. Thus, the industrial effluents contained much solids and oxygen-demanding materials with deleterious effects on the water quality, to extent that it may not be potable without treatment. There is the paramount need to treat these industrial effluents prior to discharge into the River Orogodo.

Abstract Growth response of two clones of Manihot esculenta Crantz (Cassava), TMS 30555 and TMS 30572 to Bentex T soil treatment was studied. Mycorrhizal root colonization in relation to growth parameters such as stomata size, plant water content, plant foliation, as well as height and stem circumference was examined. Bentex T, a fungicide which could be used to limit the growth of Arbuscular Mycorrhizal (AM) fungi was added to soil at the concentrations of zero 0 (control), 50, 100, 500 and 1000 ?g a.i. /g soil. Growth parameters had minimal variations (p? 0.05) between treatments in both clones of the plant. However, clonal differences at (p? 0.01) occurred in some of the growth parameters. The level of root colonization by the AM fungi affected the growth response of the plant. The untreated soil (control) with the highest AM fungi root colonization (84%) had the least plant foliation (15 and 16) and height (34.1 and 28.5 cm) for TMS 30572 and TMS 30555, respectively. The highest values obtained for stomata size (width and length) were at 50 ?g/g bentex concentration; 0.040 and 0.019mm for TMS 30572 and 0.017 and 0.007 for TMS 30555, respectively. The least value obtained for the stomata size was at the zero (0) ?g/g bentex concentration. Plants from soil treated with 100 ?g/g bentex T concentration had the highest amount of water; 75% for TMS 30572 and 76% for TMS 30555. The untreated soil had plants with the least amount of water. Implications of Bentex T soil treatment of cassava plants was discussed in relation to mycorrhizal colonization rating and some growth parameters of the test plant.

Abstract A large number of the world’s population suffer from depression and anxieties at some points in their life time, the sufferers are however sceptical about the available orthodox drugs largely because of side effects, cost and availability. This present study was aimed at evaluating the antidepressant potentials of Voacanga africana to query its ethno medicinal claim. The extract of the stem-bark of the plant was screened for its phytochemical composition, and antidepressant potentials assessed using forced swimming test (FST) and tail suspension test (TST). The results revealed presence of abundant alkaloids, but traces of saponin, terpenoid, cardiac glycosides with a meaningful antidepressant potentials at doses of 100 and 200 mg/kg by reducing the immobility duration in FST (46.19±1.212and 23.96±1.14 compared to the negative control 79.06± 0.16 and positive control~imipramine 24.13±0.405), also increasing the swimming duration from 159±0.416 of the negative control to 187.91±0.516 and 217.24±1.132 seconds respectively. Similar trend was observed in the TST, where the immobility duration was reduced from 183.207± 5.157 (negative control) to 98.62± 0.347 and 75.51± 1.366for 100 and 200 mg/kg test drug compared to 62.77± 0.426 secs (positive control). The ethno-medicinal claim of this plant is hereby justified.

Abstract Everyone tries to relieve stress by taking anti-stress drugs. However, synthetic anti-stress drugs have unwanted side effects, expensive and not readily accessible. Thus, we aimed at investigating the anti-stress activities of aqueous extract of Musanga cecropioides stem bark using forced swimming endurance stress test, anoxia stress tolerance, chronic cold resistance stress test and DPPH radical scavenging capacity. Daily administration of aqueous extract of M. cecropioides at doses of 100, 200 and 300mg/kg bodyweight one hour prior to induction of stress, at the lowest dosage (100 mg/kg)significantly increased the anoxia stress and forced swimming endurance stress tolerance times in a dose dependent manner as compared to the control groups (46.48±0.28 and 3.01±0.92 compared 28.80±0.38 and 2.25±0.08 mins), the blood glucose, blood cells, and the urinary ascorbic acid were normalised in all the tested methods including chronic cold stress. The extract also scavenged DPPH significantly in a dose dependent manner. The results showed impressive anti-stress potential and present as far as is known, the first report of the antistress (adaptogenic) activities of M. cecropioides.
