This paper presents a synthesis of a comparative leaf anatomy (lamina and petiole) of five species of the genus Terminalia found in southwest Nigeria. Collections of plants were made from different locations in Southwest Nigeria as the geographic locations of the sites of collection were also geo-referenced with a GPS device. The samples were identified at the Herbarium of Botany Department, Obafemi Awolowo University (Ife), Nigeria, and were subjected to anatomical examinations. Quantitative data were subjected to statistical analysis and the characters vary significantly (P = 0.05). Anatomical characters which separate the taxa include petiole outline, epidermal features, vascular pattern, occurence of cortical and pericyclic fibres, presence/absence of, and types of trichomes etc, all found to be useful in identification of different species. The variations in the anatomical traits could be effectively used in taxonomic delimitation of the species and are helpful characters in determining the complexes in the genus such as adaptation of the species to xeric environments. The presence of 2-3 layers of palisade mesophyll cells in Terminalia mantaly, which is an adaptation of the species to drought, is diagnostic for the species. It is suggested that a comprehensive consideration of leaf lamina and petiole anatomy should be used as basis of taxonomy.

Background: The plethora of secondary metabolites inherent in plants that could be synthesized and formulated into useful drugs for the treatment of diseases is not fully understood. This study was carried out to evaluate the antimicrobial potential of the leaves of Aspillia africana and Psidium guajava plants on some selected bacterial and fungal isolates.Methodology: Fresh and matured leaves of Aspillia africana and Psidium guajava were collected at the Federal College of Agriculture, Akure and Obafemi Awolowo University (OAU), Ile-Ife. The plants were identified and voucher deposited at the Herbarium unit of the Department of Botany, Obafemi Awolowo University, Ile-ife. The pure isolates of the bacteria and fungi were obtained from Department of Microbiology, Obafemi Awolowo University, Ile-Ife, Nigeria. The bacteria isolates were maintained on nutrient agar slant and the fungal isolates on PDA. Extraction of the plant materials using methanol, ethanol and aqueous fractions were carried out using standard protocols. The isolates were inoculated on a nutrient broth. Minimum Inhibitory Concentration (MIC) of the extracts was determined by broth dilution method while minimal bactericidal and fungicidal concentrations respectively were determined following established protocols.Results: The results showed that Bacillus cereus, Cornybacterium pyogenes, Klebsiella pneumonia and Escherichia coli were all resistant to the plant extracts. The fungal isolates; Candida albicans, Tryptophyton rubrum, Penicillium expansium, and Aspergillus flavus were resistant to Psidium guajava extract as no significant activity was observed. All the plant extracts produced considerable antimicrobial activities with Streptococcus faecalis and Staphyloccocus. aureus. whereas, these organisms were resistant to ofloxacin, sparfloxacin, chloramphenicol, augmentin, ciprofloxacin and septrin.Conclusion: This study revealed that the therapeutic properties of Aspillia africana and Psidium guajava are better enhanced with their synergistic potential to the tested microorganisms.Keywords: Aspillia africana; Bactericidal; Psidium guajava; Synergistic;therapeutic.Background: The plethora of secondary metabolites inherent in plants that could be synthesized and formulated into useful drugs for the treatment of diseases is not fully understood.

Growth and development of the pinna in three species N. cordifolia, N. exalta(i), N. exalta(ii) and N. furcans were viewed in the department of botany of Obafemi Awolowo University, IIe-Ife campus. The results showed that all the venation of the pinnae of the species consist of a mid-vein and 2 lateral series of dichotomous vein all of which terminate freely near the lamina margins. Because it seems their venation patterns are similar, this might be one of the reasons for grouping them into one genus called Nephrolepis Schott. The development and growth pattern of N. cordifolia and N. furcans was uniform and consistent, while that of N. exalta gave two forms as the young was represented N. exalta (i) and the matured as N. exalta (ii). The growth patterns showing variations in the mid-rib, fertile and sterile pinnae provided useful specific distinctions.

Background: Epithelial ovarian tumours (EOT) have complex clinicopathologic characteristics and biological behaviours. There are benign, borderline and malignant ovarian tumours and the commonest ovarian tumours in many regions are of epithelial origin. Many studies have described the histomorphological characteristics of the tumours. Objective: To describe the clinical and histopathological features of epithelial ovarian tumours. Methods: This was a retrospective review of the histopathology reports of all epithelial ovarian tumours specimens submitted to the Department of Morbid Anatomy and Forensic Medicine, Obafemi Awolowo University Teaching Hospital, Ile-Ife from January 2005 to December 2014. The EOT cases were described in terms of age, clinicopathological characteristics and distribution of histological types. Results: The frequencies of benign, borderline and malignant EOTs were 41.2%, 3.9% and 54.9% respectively and the patients were aged 23 to 94 years (mean 46.5±2.6 years). The majority of cases were often asymptomatic. Conclusion: Abdominal swelling was the most common presenting complaint while serous ovarian tumours were the most preponderant histological types.

This study investigated the foliar anatomy and venation patterns of thirteen species of the genus Diospyros in Nigeria with a view to identifying characters of great taxonomic value in the genus. Plant collections were made from different locations in Southwest Nigeria and the site of collection geo-referenced with a GPS device. Samples were identified at the Herbarium of Botany Department, Obafemi Awolowo University (IFE). Voucher Specimens were deposited in the herbarium and voucher number assigned to each of the species. The samples were subjected to foliar epidermal and venation examinations. Qualitative data were recorded as the quantitative data were subjected to statistical analysis and the characters vary significantly (P = 0.05). Epidermal and venation characters which separate the taxa include stomata type, size and index, shape and size of epidermal cell, trichome type, presence/absence of crystal/druses, as well as venation. Paxillate venation in D. suaveolens is diagnostic for the species. The presence of parenchymatous sheath over the veins and veinlets in D. tricolor is a spot character. The study reveals that leaf epidermal and venation characters are important in delimitation of species in the genus Diospyros.

This study focuses on repositioning guidance and counseling and curriculum innovation in higher education in Nigeria. Descriptive survey research design was employed in the study. The study covered four Federal universities in the South-West Geopolitical zone of Nigeria, namely University of Ibadan in Oyo State; Obafemi Awolowo University, Ile-Ife in Oshun State; University of Lagos in Lagos State; and University of Ilorin in Kwara State. The population of the study comprised 241 made up of 195 student counselors and 46 professional counselors from the four selected federal universities in the South-West Geopolitical zone of Nigeria. The sampling for the study was drawn through simple random sampling technique. Structured questionnaire was developed by the researcher using strongly agreed, agreed, disagreed, and strongly disagreed options. The questionnaire was face-validated using five experts - two in the department of Measurement and Evaluation in University of Nigeria Nsukka, one in Curriculum in Ebonyi State University, Abakaliki, one in Guidance and Counseling, Nnamdi Azikiwe University, Awka; and one in Guidance and Counseling in University of Calabar, Cross River State. The data collected were analyzed using mean and standard deviation for answering the research questions. A mean of 2.5 and above was accepted while any mean less than 2.5 was rejected. The findings of the study reveal, among other things that education, sense of industry, problem solving, conducive/enabling environment, and planning are various ways professional counselors help in repositioning curriculum innovation in higher education in Nigeria. It is also recommended among other things that both expert teachers/professional counselors and student counselors should participate in the repositioning of guidance and counseling and the design and development of innovative curriculum.
