Implications of Hegel’s Dialectical Evolution of the Spirit to the Problem of Shortcut Mentality in Nigeria
Authors: Anetoh Bonaventure Chike , Izuegbunam Hilary
Published: July 2020

This article focused on Hegel’s dialectical evolution of the spirit and its implications to shortcut mentality in Nigeria. Hegel’s evolution of the spirit is a process of change and human development, which moves from the individual to the state and then to the absolute. This process identifies and represents the world’s civilization as a gradual realization of the absolute. The fundamental questions are: What actually is Hegel’s dialectical evolution of the spirit? What is shortcut mentality? Has Hegel’s dialectical evolution of the spirit any implication for shortcut mentality in Nigeria? This article argued and insisted that Hegel’s dialectical evolution of the spirit has remarkable implications for shortcut mentality in Nigeria. A critical look at Nigeria today simply portrays a country beset by shortcut mentality in her quest for civilization. This is evidenced in many contemporary issues menacing our country today. The issues of get rich quick syndrome, quick fixes, examination mal-practice, Ponzi schemes, betting sites, corrupt practices, utopian prosperity gospel etc. are easily noticeable in almost every part of Nigeria. All these ills which have led to the malfunctioning of the economic, religious, educational, agricultural, and administrative sectors of Nigeria, are certainly the offspring of shortcut mentality. This shortcut mentality presupposes people not following the right and gradual path of change and development. It entails abhorrence of labour as well as suffering. Hence, the researchers employed analytical and hermeneutical methods to explore the implications of Hegel’s dialectical evolution of the spirit to shortcut disorder in Nigeria. This article argued that application of Hegel’s dialectical evolution of the spirit contributes enormously in combating the problem of shortcut mentality in Nigeria. Hence, the researchers recommended creativity, mutual recognition as well as positive attitude to labour and suffering as solutions to the issue of shortcut mentality in Nigeria.

Published: July 2020

The present study investigated potential enhancement factors in relation to volunteerism. Specifically, we examined how perceived locus of causality, social distance and gender may influence willingness to volunteer help for victims of road accident. The study was based on a controlled experiment among students of a university (N = 80). Hypotheses were tested simultaneously in a univariate analysis which showed non-significant influence of perceived locus of causality (H1, p > .05); significant influence of social distance (H2, p < .05); non-significant influence of gender (H3, p > .05); significant interaction of perceived locus of causality and gender (p < .01), and significant interaction of perceived locus of causality, social distance and gender on willingness to volunteer (H4, p < .01). That is, people were more willing to help when those in need are related to them. The present study contributes to theory within this research field which explain African disposition by showing that kinship and familiarity are significant predictors of willingness to provide help for victims of disaster. However, the researchers encourage all Nigerians to look beyond family ties and affiliations in providing help to people in need.

Application of Resource–Based Learning (RBL) in Nigerian Language Teaching and Learning: The Case of Ìgbò Language
Authors: Ikonne, Ugochi Happiness
Published: July 2020

In this technological dispensation, foreign languages are already on board with ICT applications and advancement with different language courses online thereby encouraging independent study of these languages. Teaching and learning of Nigerian languages cannot be said to be at a comparable rank with these foreign languages in this respect. In view of the seemingly lack of interest in the Nigerian languages study ad usage, it is believed that the application of Resource-Based Learning in this scenario will rekindle interest as well as place Nigerian languages study in a comparable terrain with their foreign languages’ counterparts. This paper explored the possibility of applying Resource-Based Learning in the teaching and learning of Nigerian languages in this ICT dispensation. It is delimited to the application of RBL on the teaching/learning of Ìgbò grammar, culture and literature. Recommendations include creating of online Ìgbò grammar lessons, running audio/visual documentaries and cutting/burning into CDs, different cultural activities, different aspects of Ìgbò oral literature like, folksongs, folktales, ballads, anecdotes, lullabies, satires, getting learners to act out same etc. Text writers are encouraged to develop varieties of children’s literature and story books.

Brechtian Methodology in Wise’s The Sound of Music: Insights into Theatre in Education
Authors: Ejiofor Benjamin Asodionye , Mark Tekena Gasper
Published: July 2020

Methods are problem solving devices for the benefit of education in society. When a method assumes regimental fixations, society suffers hackneyed bouts of limitation and contention necessitating flux. This paper examines issues of regimentalism as they affect society in Robert Wise’s The Sound of Music, and the staccato notes of change inevitably mobilizing a Brechtian methodological reading amplifying social change, in a Theatre in Education performance. Bertolt Brecht (1898-1965), accomplished German director, playwright and theorist, mobilized theatre for social change by setting up Marxist dialectics in pursuit of retrenchment of total empathy; giving free reign to critical consciousness in theatrical productions. This paper has investigated analytically, the representations of this Brechtian methodology in The Sound of Music with the manifest result that the experiment in the movie has produced a healthier and better organized society than the German regimental machine.

Roles of fresh and decomposed liver on aspects of reproduction of blowfly Chrysomya chloropyga (wied.) (Diptera: Calliphoridae)
Authors: Olatubi I.V. , Muse W.A.
Published: July 2020

This study compared the effects of fresh and decomposed liver on aspects of reproduction of the blowfly, Chrysomya chloropyga to determine the possibility of multiple generations of the blowfly on a single cadaver. The total development time from egg to adult were 8.75 and 8.50 days in the flies fed on fresh and decomposed liver respectively and were not significantly different (p=0.58) from each other. The sex ratio (male: female) was 1:1 on both diets. There was a significant difference in the survival of adults fed fresh and decomposed liver (p=0.001, 0.001). There was no significant difference (p=0.362, 0.029) in the longevity of flies fed fresh and decomposed liver. Age at first egg laying on fresh and decomposed liver were 15.00 and 7.25 days respectively on fresh and decomposed liver. Fecundity of 175.6 eggs recorded in the flies fed on fresh liver was not significantly different (p=0.804) from that (200.8 eggs) of flies on decomposed liver. Mean weights of male and female flies maintained on both diet increased from the first day to tenth day only. However, it was not significantly different (p=0.130, 0.576) from each other throughout the period of exposure. Protein concentration was significantly higher in females fed fresh liver than those maintained on decomposed liver at ages 0 to 25 days. In conclusion, decomposed liver was as effective as fresh liver in supporting reproduction of the C. chloropyga with a better performance on decomposed liver. The study also demonstrated a strong indication for more than one generation of flies on a sizeable cadaver.

Authors: Alani R. , Olayinka K. , Alo B.
Published: July 2020

Contamination of Lagos soils with persistent, bioaccumulative and toxic micropollutants (PBTs) may not only affect the non-target species residing in the soil, but also raises the concern of the possibility of the chemicals finding their way into the Lagoon and other water courses via soil run-off and leaching. In this study, soil samples were collected from three busy areas of Lagos (Apapa, Okobaba and Iddo) and analyzed for Polychlorinated Biphenyls (PCBs), Organochlorine pesticides (OCS), and Polycyclic Aromatic Hydrocarbons (PAHs). Gas Chromatography with Mass Selective Detector (GC/MSD) was used for the analyses. Iddo had the highest percentage organic carbon content of 39.39% with highest total PAHs of 2,706.93 ng/g. The highest total PCBs of 23.63 ng/g was found at Apapa 3 which was one of the three sampling points in Apapa. PCB 74 was the onlyPCB found in all the soil samples and ranged between 3.55 ng/g and 23.64 ng/g at Apapa 1 and Apapa 2 respectively. High concentrations of the following organic compounds were also obtained at the following locations- naphthalene (1,625.10 ng/g) at Iddo; dichlorodiphenyldichloroethylene (p,p'DDE ), (117.98 ng/g) at Okobaba, and PCB 74 (23.63 ng/g) at Apapa 1. The results obtained showed that the higher the municipal activity, the higher the percentage organic carbon content.

Sedimentology and maturity of Ajali formation, Benin flank Anambra basin, Nigeria
Authors: Ilevbare M. , Imasuen O.I.
Published: July 2020

The Ajali Sandstone, western flank, Anambra Basin, was studied for textural characteristics and maturity of the sediments. Grain size analysis (51 samples), thin section and heavy mineral analysis (15 samples each) and XRF fusion for metallic oxides (15 samples) were analyzed. The textural parameters show that the Ajali Sandstone are medium sand, poorly to moderately sorted, coarse to strongly coarse skewed with mesokurtic to leptokurtic grains. The thin section analysis reveals grains that are sub-angular to sub-rounded (this typifies grains that have travelled fairly long distance to the deposition site), of moderate to well sorted grains, with both monocrystalline and polycrystalline quarts-grains type, with a modal composition of Q F and L . A mineralogical maturity 90.4, 2.3 2.9 index (MMI) of 17.04, SiO /Al O ratio of 180.24, and a ZTR index of 67.96% were obtained. The values for the 2 2 3 MMI and SiO /Al O indicates mineralogical matured sediments, the ZTR index shows a chemically immature 2 2 3 to sub-mature sandstone, and the modal composition values are consistent with a texturally and compositionally matured sands. The mineralogical maturity is indicative of high degree of chemical weathering of source area. Furthermore, the high quartz and silica content make the sandstone  prospective for glass and glassware production.

Morin attenuates dutasteride/tamsulosin-induced hepatic oxidative stress in rat
Authors: Olayinka E.T. , Adewole K.E.
Published: July 2020

Dutasteride-Tamsulosin (DUT-TAM) is a combination drug for the treatment of symptoms of prostate enlargement (benign prostatic hyperplasia, BPH). Despite the efficacy, it is associated with some side effects, including hepatotoxicity. Therefore, this study investigated the attenuative effects of morin on DUT-TAMinduced organ toxicity. Twenty four male rats were divided into 4 groups (A-D) consisting of 6 animals each. Group A animals (control) were given olive oil, Group B animals were administered with DUT-TAM (5.4 mg/kg body weight of dutasteride + 3.4 mg/kg body weight of tamsulosin), Group C were given morin (100 mg/kg body weight) while group D animals were administered DUT-TAM and morin (5.4 mg/kg body weight dutasteride + 3.4 mg/kg body weight of Tamsulosin and 100 mg/kg body weight of morin). All the administrations were carried out orally for 14 days. DUT-TAM caused a significant increase in plasma bilirubin, aspartate aminotransferase (AST) and alanine aminotransferase (ALT) by 62%, 45% and 18% in the DUT-TAM treated group respectively, compared with the control (P˂0.05). However, treatment with morin significantly decreased the DUT-TAM-induced increase in plasma bilirubin concentration as well as AST and ALT activities. Furthermore, DUT-TAM administration decreased the activities of hepatic superoxide dismutase (SOD), catalase (CAT), glutathione-S-transferase (GST), as well as hepatic concentration of ascorbic acid and reduced glutathione (GSH) by 58%, 54%, 59%, 46% and 63% respectively, but increased malondialdehyde (MDA) level by 49% relative to the control (P˂0.05). However, treatment with morin significantly ameliorated the observed changes in these antioxidant parameters (P˂0.05). These data suggest that morin protects against hepatic toxicity, as well as oxidative stress induced by dutasteride-tamsulosin in rats.

Authors: Mohammed H. , Adefesobi S.A.
Published: July 2020

This paper evaluated the effects of sasobit polymer (Sasobit®) on the characteristics of asphaltic concrete with a view to investigating its suitability as an additive in asphaltic concrete. Sasobit®, bitumen and aggregates were procured from a Construction Company site office, along Shagamu-Ibadan expressway. Sasobit® modified bitumen was prepared by adding Sasobit® to bitumen with increasing weight of Sasobit® at 1.0, 1.5, 2.0, 2.5 and 3 % by the weight of the bitumen. Penetration and softening point tests were carried out on the samples and the mix-ratio for the bitumen – polymer mixture was determined. Asphaltic concrete samples with and without Sasobit® were prepared. The samples were subjected to Marshall Stability test. The stability, flow, specific density, voids filled with bitumen (VFB), air voids (VA) and voids in the mineral aggregate (VMA) weredetermined. The values of stability, flow, specific density, voids filled with bitumen, air voids and voids filled in the mineral aggregates for sample without Sasobit® were 13.63 kN 2.91 mm, 2.51, 64.64 %, 4.29 % and 18.19 %, respectively, while for those with Sasobit® at mix – ratio of 1.7 % bitumen – polymer mixture, the values were 14.67 kN, 2.41 mm, 2.55, 73.30 %, 3.96 % and 16.39 % respectively. The result showed that, Sasobit® as additive in asphaltic concrete improved its properties.

Moderate heat treatments enhance the quality of traded natural shea butter
Authors: Oyedele A.O. , Igbeneghu O.A. , Alade T.I. , Akinmusire O.O.
Published: July 2020

Natural shea butter (NSB), extracted by traditional methods resulting in its poor quality, is nevertheless widely traded within Africa and beyond due to its several useful applications. This study examined effects of simulated laboratory/domestic heat treatments on quality of the commodity obtained from a cross section of Nigerian markets. Physicochemical and microbiological qualities of NSB samples procured from four selected  markets located across three Nigerian states were evaluated by standard methods before and after graduated thermal stress treatments from 50 through 120 °C over 5, 15, or 30 min durations, respectively, and filtration at 60 °C. Mean physicochemical quality values of NSB samples determined, namely: specific gravity at 29 °C (0.90-0.94); softening, melting temperatures (33-36, 36-39 °C; respectively); acid, iodine, and saponification values (10.5- 29.3, 46.4-59.1, 110-470; respectively), were not adversely or significantly altered by the thermal treatment types and stresses. Whereas all untreated NSB samples demonstrated microbial contamination (total viable counts: 3 6 10 -10 cfu/g) with Pseudomonas, Klebsiella, Staphylococcus, Bacillus, Aspergillus, or Candida species, the graduated heat treatments produced varied sanitizing effects. Higher temperatures (100, 120 °C) gave greater and more rapid cleansing action than the lower temperatures (50, 75 °C), both intensity-ranges being aided by length of holding time. Hot filtration eliminated all the NSB contaminants. In conclusion, while untreated NSB is found grossly contaminated by microbes, unhygienic and unsafe for human use, this study has demonstrated efficient contaminants-cleansing action of heat treatments (³100 °C × ³ 30 min) on NSB, and the total sanitizing effect of hot filtration process.

Susceptibility pattern of Escherichia coli from urinary tract infections to antibiotics and methanol extracts of Olax subscorpioidea and Sida corymbosa
Authors: Idowu Philip A. , Okanlawon Babatunde M. , Salam Habeeb O.
Published: July 2020

Antibiotic resistance in urinary tract infections (UTIs), of which Escherichia coli causes about 80% of cases is on increase, causing mortality, morbidity and increased health care costs. Clinical isolates of E. coli (13) from UTIs were tested for susceptibility to standard antibiotics and extracts of Olax subscorpioidea and Sida corymbosa. Methanol extracts of the plants were screened at 20, 40, 80 and 100 mg/ml against the isolates using agar-welldiffusion method while antibiogram was determined by Kirby-Bauer disc diffusion method. The minimum inhibitory concentrations (MICs) of the plants` extracts and two antibiotics were determined by agar dilution method. The isolates were mostly susceptible to ofloxacin and 100% resistance to augmentin. Extracts of the plants showed good and dose-dependent activities, even on the multidrug resistant E. coli isolates. The zones of inhibition of the extracts ranged 9-16 mm while the MICs ranged 0.5-10 mg/ml on the isolates. This study has shown that MDR E. coli in UTIs are still prevalent and that the roots of O. subscorpioidea and stem of S. corymbosa extracts have good antibacterial activities against the isolates. The results justified the traditional use of the plants to treat infections generally and the potential utilization in the treatment of UTIs.

Published: July 2020

Erlangea tomentosa (Asteraceae) is used traditionally in the preparation of herbal remedies for management of several diseases including pain and inflammation. However, its efficacy and safety have not been scientifically validated. The aim of this study was to investigate the antinociceptive and anti-inflammatory activities of the aqueous leaf extract of this plant and its acute toxicity profile in animal models. Antinociceptive activity and anti-inflammatory activity were determined using the acetic acid-induced writhing model in mice and carrageenan induced inflammation model in ratsrespectively. The oral median lethal dose (LD50) was determined using the Lorke’s Method. The extract inhibited pain due to acetic acid significantly (p<0.05) at doses of 250 mg/kg and 500 mg/kg. The inflammation due to carrageenan was also significantly (p<0.05) reduced at dose of 500 mg/kg body weight but not 250 mg/Kg. The LD50 value of the extract was greater than 5,000 mg/kg implying that the extract was safe in 24 hours when administered in a single high oral dose. Preliminary phytochemical screening revealed the presence of alkaloids, anthraquinones, coumarins, saponins, tannins and resins. The present study has demonstrated the antinociceptive and anti-inflammatory potential of aqueous leaf extract of Erlangea tomentosa in rats and mice; thus validates the folkloric use of the plant.

An investigation of questions in Ètùló language of Benue State, Nigeria
Authors: Okoye Adaobi Ngozi
Published: July 2020

This study investigated the formation of questions in Etulo, a minority language spoken in Benue State. It specifically examines the strategies used in forming content and polar questions in the language. Data for the study were collected during a fieldtrip to Adi in Buruku Local Government Area of Benue State, Nigeria. The study shows that both content and polar questions are formed in the language through different strategies. Whereas content questions are formed through the use of interrogative words such as òle/kↄ ‘where’, òle ‘which’, ème ‘who’ emine ‘how many’ among others, the main strategy employed in polar question formation is the use of tone. In addition to tone; the language also uses such particles as gbɛ́ɛ̀ and lô in polar question formation. These particles occur at the final position of a declarative sentence to indicate that it is a question.

Published: July 2020

Drawing on the Critical Discourse Analysis grid put forth by scholars such as Van Dijk (2001a&b, 2004, 2006), Fairclough (1989, 1995, 2001, 2003), Van Leeuwen (1996, 2008), Meyer (2001), Caldas-Coulthard & Coulthard (1996), Wodak (2001), the current paper exuded how institutional social power is deployed to naturalize ideologies as common sense or common knowledge in a sample text drawn from a contemporary feminist novel, notably Sefi Atta’s Everything Good Will Come (2006). It also tried to unravel how, through discursive structures and properties, the womenfolk resist or/and transgresses the established sociocultural norms and conventional ideologies as regards gender, role assignment and power. Finally, it advocated the view that only gender-balanced power relations between men and women can ensure a fair social justice and peaceful society.

Authors: Ogefere H.O. , Umaru G. , Ibadin E.E. , Omoregie R.
Published: July 2020

This study was aimed at determining the prevalence of methicillin resistant Staphylococcus aureus (MRSA) and methicillin resistant coagulase negative staphylococci (MRCoNS) among apparently healthy students of a tertiary institution in Benin City, Nigeria. A total of 350 students were recruited for the study and nasal swabs were collected alongside demographic data. These swabs were processed microbiologically using standard techniques to recover staphylococci. Antimicrobial susceptibility and methicillin-resistance was determined using a phenotypic method (cefoxitin resistance). A total of 148 (42.3%) of 350 students were culture positive for S. aureus, while 72 (20.6%) were positive for CoNS. Students from Faculty of Dentistry showed the highest prevalence of nasal MRSA (40.0%) and MRCoNS (20.0%). Ofloxacin and gentamicin were the most active antibacterial agents against MRSA with 89.1% and 87.3% respectively been susceptible, while gentamicin was the most active antibiotic against MRCoNS (75.0%). Nasal colonization by MRSA and MRCoNS was unaffected by area of residence and gender (P > 0.05). The nasal carriage rate of MRSA and MRCoNS was 37.2% and 33.3% respectively. The study recommends periodic review of nasal colonization rates among apparently healthy subjects. Regulated use of antimicrobial agents is imperative in order to stem the tide of resistance.

Application of Multivariate Analysis in the Evaluation of Metals Distribution in Soil from Awwal Mining Site Kebbi, Nigeria
Authors: Shehu G. , Koki I.B.
Published: July 2020

Multivariate statistical techniques such as principal component analysis (PCA), factor analysis (FA), and hierarchical cluster analysis (HCA) were utilized for the evaluation of metal distribution and variations in the soil at Awwal mining site. PCA was used to determine a reduced number of three principal components (PC) indicating about 82% of the total variation in the soil samples. The result of FA justifies the results of the PCA obtained. HCA classified the soil samples at the sites into two clusters, with cluster one having the higher metal levels, while cluster two had low metal levels but characterized with dominant toxic heavy metals (As and Pb). The results of the multivariate analysis showed that natural percentage abundance in soil and mineral composition of the mining ores were the main sources of the metals under study. Due to high metal levels in the soils, disposal and management of the mining waste/tailings and rehabilitation of the mining site after closure of mining should be done with care and caution to avoid leaching of the toxic metals to surface and underground water for the protection of health and safety of the neighboring community.

Authors: S.K.  , Okpanachi I.Y.
Published: July 2020

This study determined the impact of soft drink effluent on algal composition in Kakuri stream, Kaduna South Local Government Area, Kaduna. Limnological studies of soft drink effluent were carried out for a period covering wet and dry seasons across three (3) sampling points code-named Stations A, B and C. Some physio-chemical parameters were analysed using standard methods. A total of 43 species were observed belonging to 5 families. Chlorophyceae and Cyanophyceae were the most abundant families across the three (3) stations. The total flora count was high during the dry season, 1965 cells than wet season, 1071 cells. The most dominant species were Euglena sp., Microcystis sp. and Oscillatoria sp. The pH of the three stations was more alkaline (pH 8.1) but reduces slightly at stations B and C during the months of May (pH 5.2) and August (pH 6.5). The biological oxygen demand (BOD) was relatively high across the stations, dissolved oxygen was generally low except for some months (December at station A and January at station B) that had its dissolved oxygen values above 5.00 mg/l. Euglenophyceae showed positive correlation to conductivity and BOD, Chlorophyceae was positively correlated with BOD, Cyanophyceae showed positive relationship with BOD and dissolved oxygen, Charophyceae was positively correlated with dissolved oxygen, Bacillariophyceae showed positive correlation with pH, temperature, phosphorus, BOD and dissolved oxygen. Effluent discharge and farmland run-off passed into the water body supports growth of dominant species indicating organic pollution, thus, poses a threat to the environment over a long period of time.

Published: July 2020

The ex vivo activity of the ethanol root extract of Senna occidentalis (Labaceae) on isolated rat uterus was examined in order to determine its potential in the therapy of uterine related pathologies. The ethanol root extract of S. occidentalis was investigated on the isolated uterus of rats primed with diethyl stilboestrol (0.1 mg/kg) 24 h prior to the experiment. The extract (2.5 and 7.5 mg/mL) effect on ACh (0.1 – 1.0 μg/mL)– induced contractility, in the presence of atropine (0.12 μg/mL), propranolol (8 μg/mL), CaCl2 (in Ca2+-free medium) and in the presence of 100 mM KCl was examined. The extract significantly inhibited ACh-induced uterine contractions (P< 0.05) and CaCl2- induced uterine contractions (in Ca2+-free medium) (P<0.05) in a non-competitive but concentration-dependent manner. A rightward shift of the concentration-response curve was observed in all cases. However, a bell- shaped concentration-response curve was observed for CaCl2. The inhibitory effect of the extract on ACh-induced uterine contractions was unaffected by propranolol. The extract (0.1 - 0.4 mg/mL) also inhibited KCl- induced uterine contractions. The root extract of S. Occidentalis was shown to inhibit agonist-induced uterine contractions probably through interaction with voltage-operated calcium channels.

This paper reports findings of an experiment carried out in a greenhouse to evaluate the growth and fruits quality of cucumber grown in plots irrigated with African catfish cultured wastewater compared with those irrigated with ordinary well water. Six circular African catfish culture tanks and six cucumber planter boxes were used for this experiment, three each for the fish cum cucumber integrated system and the control system of cucumber irrigated with ordinary well water. The results of the research indicated that fish cultured wastewater had a better influence on the plant height, the number, length, and diameterof leaves, as well as the diameter and length of the fruits. Six experts, each independently assessed fruits from the two treatments for juiciness, sweetness, taste and crispiness. The fruits were assessed by experts who though were aware of the purpose of the evaluation, did not know the identity of fruits they were assessing. The fish effluent fertigated cucumber fruits had a higher mean score in juiciness, sweetness, taste and crispiness. Wastewater from the African catfish production system thus exhibits the potential for reuse in the production of cucumber plants as it had no negative effect on the organoleptic quality of cucumber fruit produced.

Ex-Vivo Uterine Activity of Theobroma Cacao (Malvaceae) Aqueous Seed Extract and Cymbopogon Citratus (Poaceae) Aqueous Leaf Extract - A Preliminary Investigation
Authors: Bafor E.E. , Omogiade G.U.
Published: July 2020

There is a need to develop new drugs from natural products for the safe and effective management of female reproductive disorders. This research was therefore aimed at the investigation of two commonly consumed natural products on uterine function. The ex vivo uterine activity of Theobroma cacao aqueous seed extract and Cymbopogon citratus aqueous leaf extract was investigated on non pregnant mouse uteri. The effect of T. cacao (0.1 mg/mL) and C. citratus (0.1 mg/mL) on spontaneous uterine contractility and in the presence of oxytocin (11.54 nM) was examined. This study showed that T. cacao elicited a significant increase (p < 0.05) in the amplitude of spontaneous uterine contractions with no significant ch ange in the frequency, which was similarly observed with C. citratus leaf extract. An increase in amplitude and frequency of oxytocin induced uterine  contractions was observed in the presence of T. cacao while with C. citratus there was a significant (p< 0.05) reduction in amplitude and non significant reduction in frequency of oxytocin induced uterine contractions. The uterotonic effect of both extracts in the absence of agonists observed maybe as a result of constituents with agonistic activity on intra cellular calcium. This study has shown that T. cacao and C. citratus could stimulate uterine activity and may therefore be useful in the management of uterine contractility disorders.

Shell Morphometry is a fundamental tool for the evaluation of phenotypic stocks. The shell growth pattern and percentage flesh yield of Galatea paradoxa from Itu Creek in Niger Delta were investigated using standard morphometric methods. The mean in centimeter (cm) of 9.71±0.09, 35.02±0.22, 23.21±0.12, 37.11±0.25, 29.31±0.16 and 7.32±0.04 were recorded for shell length, maximum width, maximum height, nacre length, nacre width and hinge length respectively. Mean live weight of 115.70±1.09 g, mean flesh weight of 37.91 ± 0.23g and mean shell weight of 66.82±0.97 g were recorded for this species. Galatea paradoxa showed negative allometric growth (b < 3) while the correlation coefficients (r) in all the shell variables were far below „1‟, indicating a week correlation between the parameters. About 19% of the live weight of the clam is made up of flesh by weight.

Brine Shrimp Cytotoxic and Lemna minor Phytotoxic Evaluations of the Methanol Extracts of the Leaves, Stem and Root Barks of Sacrocephalus latifolius
Authors: Ikpefan E. O.
Published: July 2020

This work was aimed at evaluating the probable toxicity of the methanol extract of the leaf, stem bark and root of Sacrocephalus latifolius on Artemia nauplii and fronds of Lemna minor. The powder samples of the three morphological parts were independently extracted with soxhlet extractor apparatus using 95% methanol and were dried with aid of ritory evaporator at 40ºC. The extracts were subjected to biological activities involving brine shrimp cytotoxicity and Lemna minor test for phytotoxicity at 10-100 μg /mL respectively. The experiment was done in replicates of three. Concentration-dependent cytotoxic and phytotoxic activities were recorded for the extracts. The results revealed that extract of the leaves demonstrated significant cytotoxic and phytotoxic activities over the other parts of the plant. At 10μg/mL, the three extracts recorded little or no cytotoxic activity. However, at the maximum concentration of 1000 μg /mL, cytotoxicities of 66.67 and 3.33% were recorded for extracts of the leaf and root bark respectively, while the extract of the stem bark showed no activity. However, the LC50 of the leaf was 467.74μg /mL, and that of the other extracts were observed to be ˃1000μg /mL. The results for phytotoxicity followed a similar trend with the extracts of the leaf and root bark recording 52.96 and 23.33 % phytotoxicities respectively at 1000 μg /mL. Having shown a higher activity over the other extracts, the leaf extract of S. latifolius could serves as a natural alternative pesticide and weedicide.

Published: July 2020

In this research, starch was extracted from fresh sweet potato and was used to prepare starch-g-acrylamide hydrogel using free radical polymerization method with potassium per sulphate and N’N-Methylene bisacrylamide as initiator and cross-linker, respectively. The swelling capacity and pH sensitivity of the synthesized hydrogel were investigated in solutions of various pH (1-12). The drug loading and release experiment was also carried out using promethazine (PMZ) as the model drug at 25oC and 37oC, respectively while the release study was carried out in an enzyme-free simulated gastric intestinal fluid (SGF) and simulated intestinal fluid (SIF). The result showed a 905% swelling at pH 11, suggesting increased swelling capacity at higher pH values. Drug loading result indicated 99% of the drug was entrapped by the hydrogel as confirmed by UV-visible spectrophotometry. SIF and SGF Simulation indicated a 24% and 9% drug release for the first ten hours. At the end of 48 hours the release was 96% and 89%, respectively indicating the hydrogel released more promethazine in SIF than in SGF. The results obtained in this work suggest that starch-graft-acrylamide hydrogel is a potential vehicle for oral drug delivery.

Balanites aegyptiaca is a medicinal plant that has been used in a variety of folk medicines in India and Africa for the treatment of different ailments such as syphilis, jaundice, liver and spleen problems, epilepsy, yellow fever. This research aimed at investigating the phyt ochemical constituents, acute toxicity, anti inflammatory and antinociceptive activities of the ethanol extract of Balanites aegyptiaca (EEBA) leaves. The plant material was extracted using ethanol as solvent. The dried ethanol extract was screened for the presence of phytochemicals; Acute toxicity (LD50) was  determined using Lorke’s method while anti inflammatory and antinociceptive activities were evaluated using hot plate and tail immersion methods in albino rats. Results of the study revealed that phyto chemical constituents such as flavonoids, carbohydrates, saponins and glycosides were found in the EEBA, intraperitoneal LD 50 of 2154 mg/kg shows the substance is non toxic. The EEBA produced significant (p <0.05) and dose dependent anti inflammatory and a ntinociceptive activities at all test doses (200, 400 and 600 mg/kg). The presence of the phytochemicals detected might be responsible for the demonstrated anti inflammatory and antinociceptive activities in the plant extract.

Published: July 2020

Pigeon dropping has been known to be a reservoir for Cryptococcus neoformans. In this research, attempt has been made to screen and select for this life threatening organism using temperature (thermotolerance) and urease test sequentially. Fourteen (14) samples from pigeon droppings were collected from three markets in Benin City. Isolates obtained from these samples were subjected to urease and temperature test. The results showed that 10 isolates that were positive for temperature were equally positive for the urease tests, with highest growth rate 37°C recorded for samples obtained from New Benin (NB3). This experiment demonstrates the possibility of isolating C. neoformans at minimum temperature of 37°C thermotolerance and urease activity tests. Pathogenicity studies are recommended to further understand host – pathogen relationships.

Malaria remains a major public health problem in the tropics. According to WHO estimates, sub-Saharan Africa continues to carry a   disproportionately high share of global malaria burden. Oxidative stress plays significant role in malaria pathogenesis. Recently, there is increasing  effort to develop more potent antimalarials from plant source. Brachystegia eurycoma and Mondia whitei are used locally for malaria treatment. Medicinal plants used in therapy quite often possess antioxidant activities as a result of its inherent phytoconstituents. The phytochemical composition of Brachystegia eurycoma and Mondia whitei were qualitatively examined. The antioxidant activities of the methanolic extracts of the leaves of two medicinal plants were determined using 2, 2-diphenyl-1-picrylhydrazyl (DPPH) antioxidant assay. The Brine shrimp lethality assay (BSLA) and Lorke‘s acute toxicity study were used to estimate their toxicities; while Peter‘s 4-day chemosuppresive test was employed to evaluate their antimalarial activities. The flavonoid and saponins content were particularly high in both plants. Using ascorbic acid as reference (IC50 9.26 μg/mL), the antioxidant IC50 values of B. eurycoma and M. whitei were 11.14 μg/ mL and 19.81μg/mL respectively; the BSLA LC50 were 1.8 mg/mL and 1.2 mg/mL; acute toxicity LD50 were 5000 mg/kg and 4500 mg/kg. Brachystegia eurycoma showed stronger daily average antimalarial activity (62.0 %) than Mondia whitei (39.3%), the standard drug, chloroquine, was 85.4%. The chloroform fraction of Brachystegia eurycoma was the most active with (65%) daily average suppression. This suggests that the extracts of leaves of the plants have good antioxidant activities, are non-toxic and supports their antimalarial use in ethnomedicine.
