Antibacterial Activity of Phytochemicals in Ficus thonningii Leaves Extracts Against Some Selected Pathogenic Bacterial Prevalent in Sickle Cell Anemia
Get PDFSickle cell anemia (SCA) is caused by point mutation involving substitution of valine by glutamic acid, clinical
cause of this is that SCA patients are immunocompromised hence, prone to bacterial infections. Escherichia coli,
Klebsiella. pneumoniae, Salmonella typhi, Streptococcus pneumoniae and Staphylococcus aureus are some of the
bacterial associated with SCA. Here we investigated the antibacterial activity of extracts of Ficus thonningii leaves used by ethnomedicinal practitioners in the management of infections in SCA patients. The antimicrobial activity was determined based on average diameter of zone of inhibition (AVDZI), minimum inhibitory concentration
(MIC) and minimum bactericidal concentration (MBC) while, structure of compounds FTH1 (Bergapten), FTH2
(Protocatechuic acid) and FTH3 (Methyl ferulate) were identified based on Nuclear Magnetic Resonance (NMR)
analysis. The results indicated that the crude extracts of methanol (MCE), hexane (HCE), chloroform (CCE) and
methanol-water (MWCE) had AVDZI of ≥ 12.1 ± 0.12 mm, ≥ 11.0 ± 0.00 mm, ≥ 10.2 ± 0.25 mm and ≥ 12.1 ±
0.21 mm respectively while the isolated compounds FTH1, FTH2 and FTH3 had AVDZI of ≥ 10.1 ± 0.10 mm, ≥ 9.1 ± 0.12 mm, ≥ 7.1 ± 0.24 mm respectively. The AVDZI results was tested for statistical significance using one way ANOVA and Tukey Posthoc test, and was considered significant at p < 0.05. Our findings suggested that F. thonningii leaves extracts including compounds isolated from them are potential antibacterial agent and justify their use as antibacterial prophylactics in the management of infections in SCA patients by ethnic people in Nigeria

Appraising Landscaping in Chukwuemeka Odumegwu Ojukwu University, Uli Campus, Anambra State, Nigeria
Get PDFAmid the growing benefits for proper landscaping design and planning, there is the need
for man to be in a decent, well-organised and aesthetically pleasing environment. This
could add value to concentration of staff and students in the campus as well as provide
relaxation points within the campus. The landscaping quality of Uli campus of
Chukwuemeka Odumegwu Ojukwu University deserves attention in view of its state.
The objectives of this paper are to appraise the quality of the present status of
landscaping in the campus and assess the perception of people on the quality of present
landscape in the campus environment. This is with a view to providing a feedback for
improved landscape management of the University campus environment. The
methodology adopted for this research was survey design. The focus was on academic
staff of the Faculty of Environmental Science of the university randomly selected from
the research population. This selection was premised on their assumed knowledge of the
subject matter. Data was collected from primary sources using questionnaires and
observation schedules. Data analysis was done at the univariate level using Statistical
Package for Social Sciences (SPSS). The outcomes show that the landscape
environment within the campus is not in a good state. Some contributing factors to this
were attributed to inadequate maintenance operations, inadequate provision of funds
and inadequate equipment for maintenance operations, among others. The study
recommends involving professionals in the built environment in the physical planning
unit and works department of the institution to handle landscaping concerns within the
campus, provision of enough funds for landscape improvement and maintenance
operations, incorporating man-made features such as trash cans, street lights, sculpture,
defined pedestrian walkways, paving and other road furnishings incorporated into the
landscape. The university management may revive an existing landscape committee that
would liaise with the horticulture unit of the faculty of Agriculture and have adequate as
well as regular supply of new plants for possible replacement of dead plants and/or
planting of new ones where they are desired. A redesign of the general landscape of the
campus is desirable

Nanochitosan derived from marine annelids
Get PDFThe phylum Annelida consists of segmented worms which are identified with the pres
ence of coelom which is a body cavity (or coelom), bristles that are moveable (or Setae/
Chaetae), and a segmented body through annulations that goes transversely. They are
made up of a complex group containing up to 22,000 well-known species (Aguado et al.,
2014). Annelids are coelomated organisms which are triploblastic, bilaterally symmetrical
and coelomate organisms, usually have a circulatory system that is closed and a nephridia
which plays a vital role in osmoregulation. Their sizes vary from millimeters to meters
long and also possess feeding structures of varying complexities, different morphology of
chaetal and sensory organs. They ubiquitous and distributed all over the world right from
the deepest sediments of marine habitants to moderate altitudes of fresh water habitants as
well as from the temperate to the tropic region (Donald and Bruno, 2009).
This phylum of invertebrate animals is divided into three groups: hirudinea, poly
chaeta, and oligochaeta. The marine annelids which are members of the class polychaeta
have been found to display the more primitive features of the phylum (Susan et al.,
2015). There are 6000 known species of the polychaetes and most of them are found
floating ocean, wandering at the bottom or found living in the tube built by them.
They have varying color ranging from dull to brilliant while of the species are known
to be bioluminescent, such as Chaetopterus, Terebella, and Cirratulus (Hastings, 2011). The
earthworms belong to the class Oligochaetae, which are known to live primarily in
damp soils; few members live in fresh water and estuarine habitat. The leeches are the
major member of the class Hirudinea (Bleidorn, 2009)
