Haematological Analysis

Abstract Pre-slaughter White Fulani cows were purposively sampled on the basis of body condition: emaciated (n=37) and non-emaciated (n=37), with the objective of understanding the intricate interplay of oxidative stress, trace elements and haematological variations during emaciation. Blood was drawn from the jugular vein for haematological analysis and accruing serum was used for the evaluation of malondialdehyde (oxidative stress marker), antioxidant enzymes and compounds, serum protein, electrolytes as well as trace elements. Significant (p < 0.05) differences between the emaciated and non-emaciated cows were established only in the values of copper and reduced glutathione (GSH), which were lower in emaciated cows (EC). None of the animals had packed cell volume (PCV) below the normal reference range, however values above the normal (> 46%) were seen, suggesting dehydration. The PCV in emaciated cattle was slightly lower than in non-emaciated cows. The mean malondialdehyde concentration in non-emaciated cattle was higher than that in emaciated ones, however antioxidants SOD, catalase, Vitamin C and zinc were slightly higher in non-emaciated cows (NEC). Overall, the results indicate that emaciation in studied White Fulani cows (WFC) displayed a variable redox homeostasis confounded by dehydration and depletion of antioxidants.

Alkaloid Fraction

A disruption in the equilibrium between the generation of reactive oxygen species and antioxidant defense enzymes is referred to as oxidative stress. In the present study, we planned to identify the hepatoprotective effect of Phyllanthus amarus alkaloid rich fraction in wistar strain albino male rats. The hepatic damage was induced by the D-galactosamine and ameliorative effect was tested with alkaloid rich fraction of P. amarus by measuring oxidative stress markers such as G6PDH, LDH, SDH, MDH and GDH in the liver tissue. Activity levels of G6PDH, SDH, MDH and GDH were significantly decreased in D-galactosamine induced hepatitis rats when compare to normal control rat group, while their activities were significantly increased in hepatitis rat group that supplemented with alkaloid rich fraction of P. amarus. In contrast, LDH enzyme activity of liver was significantly increased in the hepatitis rat group when compare to normal control rats, while its activity was significantly decreased in hepatitis rats treated with alkaloid fraction. In conclusion, it is very clear that alkaloid fraction of P. amarus has hepatoprotective property with respect of decreasing oxidative stress by regulating oxidative stress marker enzymes. The isolation and identification of specific alkaloid compounds with hepatoprotective properties and anti-oxidative stress will require much further research.

Background: PCOS is a condition with significant decrease in antioxidant with an increased risk of oxidative stress. Antioxidant supplementation has been shown to improve insulin sensitivity in PCOS and may improve outcome of management of PCOS. Objectives of this study were to determine the oxidative stress level of PCOS patients, to assess the effect of antioxidant supplementation on the outcome of management of PCOS and to compare with a control group.Methods: The study was a single blind randomised control trial involving 200 patients with PCOS. The study was conducted at Usmanu Danfodiyo University Teaching Hospital Sokoto. They were randomly divided into intervention and control groups and base line serum levels of oxidative stress marker, antioxidant enzymes, vitamins and minerals were determined. Antioxidant supplementation and placebo were given to the intervention and control groups respectively. All the patients had ovulation induction with clomiphene citrate and were followed up for 6 months. Outcome measures were clinical pregnancy or menstrual regularisation. Level of significance was <0.05.Results: There was statistical significance in the serum levels of oxidative stress marker, antioxidant enzymes, vitamins and minerals between the two groups (post intervention). Glutathione peroxidase (p = 0.001), superoxide dismutase (p = 0.0001), catalase (p= 0.0369), melondialdehyde (p= 0.007), Vitamin A, Vitamin C, Vitamin E (p = 0.0001), zinc and copper (p = 0.0001). The clinical pregnancy outcomes were 22 (22%) versus 2 (2%); live births 18 (18%) versus 2 (2%) and menstrual regularisation 48 (48%) versus 46 (46%) in the intervention and control groups respectively.Conclusions: Antioxidant supplementation in this study significantly affected pregnancy rate in patients with PCOS. Larger studies are suggested to revisit the conclusion of the Cochrane review that antioxidants supplementation had no significant role in female infertility.

The Relationship

Background: Ischemia-modified albumin (IMA) is an oxidative stress marker used to assess the presence and severity of oxidative stress. This marker was first used for early diagnosis of myocardial ischemia. Materials & methods: A variety of IMA studies were carried out to show the effect of oxidative stress on gynecological disorders. Conclusion: This analysis summarizes the literature by conducting electronic research on the relationship between IMA and gynecological disorders.
