This study examined the watering regime that will enhance best
germination and early seedling growth of Tetrapleura tetraptera. Seeds and
seedlings of the plant were subjected to five different watering regimes viz:
watering once weekly with 50ml, watering twice weekly with 50ml, watering once
weekly with 100ml, watering twice weekly with 100ml and watering with 100ml
only on the day of planting (as control for the seeds experiment), no watering (as
control for the seedling experiments). The results of the experiment showed that
watering once weekly with 100ml was the most effective watering regime for
enhancing seed germination. This resulted in 85% germination, followed by the
seeds watered twice weekly with 50ml (65%) and watering twice weekly with
100ml (50%). Other watering regimes were less or not effective. While watering
twice weekly with 100ml was the most effective watering regime for enhancing
seedling growth in this plant. This resulted in significantly highest plant height,
number of leaves and broadest leaf area (22.00 cm, 15.00 and 27.51cm2
respectively) at the third month of planting. It also resulted in highest seedling stem
girth (3.50 cm) though this was not significantly different from seedling treated with
other watering regimes except for seedling treated with no watering which gave 0.20
cm. The results of these studies demonstrated that water supply may be a limitation
for raising Tetrapleura tetraptera in the nursery as the soil moisture influenced
germinability and early growth of this plant.

Drug-induced liver injury is a potential complication of all medications
because the liver has a central role in the metabolism of drugs and toxic substances.
This study was designed to evaluate the hepatoprotective activity of the methanolic
extract of Gymnema slyvestre leaves on acetaminophen-induced liver damage in
wistar rats. The experiment was carried in three phases. In Phase I, the
hepatoprotective activities of the methanolic extract of the leaves was determined by
assaying for some liver function indices (AST, ALT & ALP) on acetaminopheninduced liver damage in rats. In phase II, the methanolic extract of the leaves was
further fractionated with chloroform, ethylacetate and n-butanol to obtained
chloroform, ethylacetate, n-butanol and residual extracts respectively; and the effect
of these fractions on liver function (AST, ALT & ALP) was determined.

There is dearth of information on the gene frequencies of ABO and
Rhesus blood groups, secretor status, PTC taste perception and haemoglobin
variants in Osun State, Nigeria and previous studies have been based on
heterogeneous population. We wanted to have information on the frequency
distributions of these traits in Osun State and among a homogeneous population. A
total of 555 individuals comprising 308 male and 247 female indigenes of Ore
community participated in this study. Participants’ blood samples were typed for
ABO, Rhesus blood groups and haemoglobin genotype, saliva samples were
analysed for ABH secretory status and PTC taste perception was determined using
PTC strips. The frequencies of O, A, B and AB individuals were 41.6%, 30.8%,
21.6% and 6.0% respectively, those of Rh positive and Rh negative were 89.9% and
10.1%, those of secretors and non-secretors were 69.2% and 30.8% respectively
while those of tasters and non-tasters were 56.6% and 43.4% respectively. The
observed ABO blood group, Rhesus factor, secretor status, PTC taste perception
distributions did not differ significantly (p = 0.986, p = 0.943, p = 0.926, p = 0.864
respectively) from those expected under the Hardy-Weinberg equilibrium. The
allelic frequencies for ABO were p(A) 0.205, p(B) 0.149 p(r) 0.645, those for
Rhesus factor were D(0.682) and d(0.318), those for secretion and non-secretion
were Se (0.445) and se(0.555) respectively while those of tasting and non-tasting
were T(0.341) and t(0.659) respectively. Four haemoglobin genotypes in the order
AA (68.6%) > AS (26.7%) > AC (3.8%) > SS (0.9%) were observed with allelic
frequencies A(0.839), S(0.142) and C(0.019). This study has provided information
on the frequency distributions of the studied genetic indices in Osun State. The
information provided herein can be used to give medical and genetic counsel to the
people of the State.
