    Cross-sectional study of antioxidant status in normotensive and hypertensive pregnancy
    (Tropical Journal of Obstetrics and Gynaecology, 2011) Owolabi, A. T.; Marcel, T. T.; Fakunle, Julius B.; Togun, R. A.; Akinola, N. O.; Asaolu, M. F.; Fasubaa, O. B.; Bisiriyu, L. A.; Kuti, O.
    Objectives: The study measured the concentrations of antioxidants in women during pregnancy and the Post Partum Period (PPP) with a view to investigating their role in the aetiology of pregnancy induced hypertension (PIH). Study Design: Informed consent was obtained from 105 women who were divided into three groups: 15 age and parity matched normotensive non-pregnant (control group), 45 normotensive and 45 hypertensive pregnant women. The two groups of pregnant women were divided into three groups of 15 each and studied in the second and third trimesters and PPP respectively. Venous blood was obtained from all the participants for measurements of some antioxidants (uric acid, albumin, catalase and vitamin C). Data were analyzed using descriptive and inferential statistical methods. Results: The results show that the mean concentrations of catalase, albumin, vitamin C and uric acid for the control were 3.1 ± 0.18 µ/l, 46.6 ± 6.6 g/l, 0.38 ± 0.01 mg/dl and 0.16 ± 0.03 mmol/l respectively. The mean concentration of all antioxidants except uric acid were significantly lower during pregnancy when compared with controls (t= 2.06; p<0.01). In the normotensive group of pregnant women, vitamin C was the only antioxidant that showed significant higher concentration when the second trimester concentration and third trimester concentration were compared (t=2.06; p<0.05). Uric acid levels were significantly higher (t=2.06; p<0.05) and nd rd catalase and vitamin C levels were significantly lower in the hypertensive group during the 2 and 3 trimesters (t=2.06; p<0.05). There was a tendency for all antioxidant concentrations to return to normal values during the PPPin the normotensive group; however in the hypertensive group, uric acid levels remained significantly higher (t=2.06; p<0.05). Conclusion: In conclusion this study showed that pregnancy generally reduced the concentration of antioxidants but vitamin C levels were higher in late pregnancy of normotensive women. Therefore higher levels of vitamin C may protect against PIH.

    Evaluation of in-vitro antioxidant activities of methanol extracts of Persea americana and Cnidosculus aconitifolius
    (Pak J Nutr, 2010) Asaolu, M. F.; Asaolu, S. S.; Fakunle, Julius B.; Emman-Okon, B. O.; Ajayi, E. O.; Togun, R. A.
    The present study was undertaken to investigate the antioxidant activities of Persea americana and Cnidosculous aconitifolius. The in-vitro antioxidant activity of the methanol extracts of the leaves of Persea americana and Cnidosculous aconitifolius was evaluated using various experimental methods such as 1,1-diphenyl-2-picryl-hydrazyl (DPPH), nitric oxide and reducing power radical-scavenging activity assay. Phytochemical screening as well as the amounts of total phenol and flavonoids were also determined. The present study revealed that both the methanol extracts of the leaves of Persea americana and Cnidosculous aconitifolius possess significant antioxidant activities. However, Persea americana was found to have higher radical scavenging activity than Cnidosculous aconitifolius but the phenol content of Cnidosculous aconitifolius was higher than that of Persea americana whereas Persea americana was observed to possess more flavonoids than Cnidosculous aconitifolius.

    Prostaglandin levels and semen quality in male partners of infertile couples in Ile-Ife, Nigeria
    (Tropical Journal of Obstetrics and Gynaecology, 2011) Emma-Okon, B. O.; Fasubaa, O. B.; Togun, R. A.; Fakunle, Julius B.; Awoniyi, A.; Adediran, T.
    The study revealed a high percentage of men with sub-normal semen .Range of PGF2á in the subjects was 0.15-11.05µg/ml with a mean of 2.77± 0.23 µg/ml while that of PGE was 21.8- 652.0 µg/ml with a mean of 248.79± 13.88 µg/ml. Among men with normal semen profile, mean PGF2á and PGE levels are 2.1± 0.32 µg/ml and 325.1± 28.3 µg/ml respectively while that in semen of men with subnormal semen are 3.0± 0.28 µg/ml and 225.1 ± 15.1µg/ml respectively. Despite the wide range of PG values in all the groups, significant differences(P<0.05) were found to exist between the PG values of men in the normal and sub normal semen groups. Significant differences were also found when they were grouped according to sperm count alone. However, differences observed when in the grouping according to other individual semen characteristics are not significant. Conclusion: The wide range of PG values obtained in all the groups make it difficult to make far reaching conclusions as to the relationship between PG levels and semen quality. Further research is desirable in establishing the role of PGs in sperm function.
