The role of platelet and plasma markers of antioxidant status and oxidative stress in thrombocytopenia among patients with vivax malaria
Araujo, Claudio F;Lacerda, Marcus VG;Abdalla, Dulcineia SP;Lima, Emerson S;
Memórias do Instituto Oswaldo Cruz , 2008, DOI: 10.1590/S0074-02762008000600001
Abstract: malaria remains an important health problem in tropical countries like brazil. thrombocytopenia is the most common hematological disturbance seen in malarial infection. oxidative stress (os) has been implicated as a possible mediator of thrombocytopenia in patients with malaria. this study aimed to investigate the role of os in the thrombocytopenia of plasmodium vivax malaria through the measurement of oxidant and antioxidant biochemical markers in plasma and in isolated platelets. eighty-six patients with p. vivax malaria were enrolled. blood samples were analyzed for total antioxidant and oxidant status, albumin, total protein, uric acid, zinc, magnesium, bilirubin, total thiols, glutathione peroxidase (gpx), malondialdehyde (mda), antibodies against mildly oxidized low-density lipoproteins (ldl-/nldl ratio) and nitrite/nitrate levels in blood plasma and gpx and mda in isolated platelets. plasma mda levels were higher in thrombocytopenic (tcp) (median 3.47; range 1.55-12.90 μmol/l) compared with the non-thrombocytopenic (ntcp) patients (median 2.57; range 1.95-8.60 μmol/l). moreover, the ldl-/nldl autoantibody ratio was lower in tcp (median 3.0; range 1.5-14.8) than in ntcp patients (median 4.0; range 1.9-35.5). finally, gpx and mda were higher in the platelets of tpc patients. these results suggest that oxidative damage of platelets might be important in the pathogenesis of thrombocytopenia found in p. vivax malaria as indicated by alterations of gpx and mda.
Lipid peroxidation and antioxidants in hyperlipidemia and hypertension
Biological Research , 2000, DOI: 10.4067/S0716-97602000000200010
Abstract: lipid peroxidation and lipid-derived oxidized products have been implicated in the pathogenesis of a variety of human diseases. to clarify the role of oxidative stress in essential hypertension and hypercholesterolemia the in vitro oxidative susceptibility of ldl, the antioxidant status and the lipid peroxide content of blood plasma were examined in hypercholesterolemic (hc), hypertensive (h), hypercholesterolemic/hypertensive (hh) and normolipidemic/normotensive subjects (n). plasma ascorbate and lipid-soluble antioxidants were lower, while ldl oxidizability, ce-ooh and tl-ooh were higher in h, hc, and hh groups than in the n group. no difference was observed among groups for pl-ooh and isoprostanes. in summary, the results show that: 1) lipid- and water-soluble antioxidants are lower in hypercholesterolemic and hypertensive patients as compared to normal subjects, whereas the lipid peroxide content and the ldl susceptibility to oxidation were higher; 2) total cholesterol, ldl-cholesterol, apob and ce-ooh were negatively correlated with the content of a-tocopherol; 3) there was a positive correlation between the content of lipid-soluble antioxidants and the resistance of ldl to oxidation; and 4) ce-ooh and tl-ooh were positively correlated with total cholesterol and ldl-cholesterol.

Is ‘divine healing’ in the ‘faith movement’ founded on the principles of healing in the bible or based on the power of the mind?
SP Pretorius
HTS Theological Studies/Teologiese Studies , 2009,
Abstract: Many people plagued with incurable diseases or diseases that seem to be resistant to medical treatment, in desperation turn to preachers who claim to administer divine healing. These divine healers make certain claims, based on their interpretation of the Scriptures and a so-called revelation of God’s will. They furthermore preach that healing and health are included in atonement and that nobody should be sick. Illness is an indication of a lack of faith on the part of the believer. It could also be attributed to an attack from the devil. In order to obtain healing, a process of ignoring the symptoms, followed by an unyielding and repeated confession of the healing needed, based on selected verses from the Scriptures, is proposed. This article is based on the contention that the healing practised by these divine healers is nothing more than a ‘mind-over-matter’ approach, leading people into confessing over and over that they have been healed. These practices are reminiscent of the utilisation of affi rmations that lead to positive thinking, which will evidently result in a change of behaviour on the part of the confessor. No indication of Godly intervention seems to be evident in this healing ministry, and neither is any submission to the will and purpose of God.
Spiritual abuse under the banner of the right to freedom of religion in religious cults can be addressed
SP Pretorius
Acta Theologica , 2011,
Abstract: The international endeavour to afford the right to freedom of religion to all world citizens is essential. This right ensures that people can choose their own religion and freely participate in the practice thereof. Although the conventions on religious freedom prohibit the use of unethical coercion in order to proselytise and retain members, the enforcement of this prohibition is problematic. Underlying psychological processes that induce members in cults to engage in radical behaviour changes cannot be proved without reasonable doubt in any legal action. The conclusion reached in this article is that although – on paper – the right to religious freedom ensures freedom in the sense that people can choose their religion, it cannot ensure that worship in any religion is a voluntary act on the part of the participants. On the one hand, religious freedom has opened the world of religion to people; but at the same time, it has also created a vague, or “grey” area where abuse can flourish under the banner of so-called “freedom”. Freedom that is not clearly defined can lead to anarchism. Abuse in religious cults can be addressed by cultivating public awareness through the gathering and distribution of information on the abusive practices of these groups.
