ABSTRACT
This study aimed to investigate the presence of oxidative stress and inflammation in ischaemic stroke patients by measuring malondialdehyde [MDA], total antioxidant status [TAS], and highly-sensitivity C-reactive protein [hsCRP] in the early post-ischaemic period, and to determine the role of Ginkgo biloba therapy in correcting the markers of oxidative stress and inflammation. This study was conducted at Ibn Seena Hospital, Mosul City, Iraq and included 31 cerebrovascular accident [CVA] patients and 30 healthy controls. Ischaemic stroke patients were divided into two groups: group I [n = 15] received conventional therapy; group II [n = 16] received conventional therapy with G. biloba [1500 mg/day] for 30 days. Blood samples were obtained from patients and controls before treatment and assays done of serum levels of MDA, TAS, and hsCRP. For CVA patients, a post-treatment blood sample was taken and the same parameters reassessed. Compared with the controls, patients' serum levels of MDA, and hsCRP were significantly higher [P
ABSTRACT
To assess serum level of malondialehyde [MDA], total antioxidant status [TAS] as a representative of oxidative stress, with immunoglobulin levels [IgG, IgA, IgM] in patients with primary brain tumors at diagnosis and one month after surgical resection in comparison to healthy controls. The study was conducted in Iben-Seena Hospital in Mosul city Iraq. Thirty-seven patients with primary brain tumors were included in the study, later proved by histopathology to be cases of meningioma [24 cases] and glioma [13 cases]. Also included 32 apparently healthy, age and sex matched subjects as a control group. Initially, blood samples were taken from both the patients and controls and assessment of serum MDA, TAS and immunoglobulin levels [IgG, IgA, IgM] were done, later for the patients group one month after surgical resection of the tumor another blood samples were taken and assessment of the same parameters mentioned above were done again. Serum MDA was found to be significantly higher [p<0.001] and serum TAS was significantly lower [p<0.001] in patients with primary brain tumors [both meningioma and glioma] prior to surgical resection in comparison to controls. Postoperatively, there was a significant reduction [p<0.001] in serum MDA levels with an increase in TAS [which was slightly significant in gliomas and insignificant with meningiomas]. With regard to serum immunoglobulin levels, there was a significant increase in serum IgG [gliomas p<0.05; meningioma p<0.001] preoperatively compared with controls, with a significant reduction [p<0.001] in the serum levels of IgG, IgA and IgM postoperatively in comparison to preoperative values. Primary brain tumors [both meningioma and glioma] as a disease carry a substantial effects on oxidant/antioxidant status and on serum immunoglobulin levels as part of the humoral immunity so as the surgical removal of the tumor mass as a way of therapy
