Pulmonary tuberculosis (PTB) is a dangerous bacterial infection that attacks the lungs. It has long been documented that there is an increase circulating levels of free radicals and oxidative stress markers in TB subjects. Malnutrition and deficient antioxidant capabilities further complicate the patient’s situation. The aim of this study is to determine the serum levels of malondialdehyde (MDA) and superoxide dismutase (SOD) in pulmonary tuberculosis patients and normal volunteers at Rasheed Shekoni Teaching Hospital Dutse, Jigawa State, Nigeria. The present study consists of one hundred and thirty-four (134) subjects, Ninety (90) among which are diagnosed TB patients and forty-four (44) apparently healthy controls attending Rasheed Shekoni Teaching Hospital Dutse. Venous samples were collected from ninety consecutive, consenting PTB on drugs and those that have not started medications. MDA levels were analysed using the method of Nadigar et al (1986). The mean values of MDA in the 24 tuberculosis infected males who are yet to commence drug was 4.0±0.32, 2.8±0.53 in those that are on drugs and 2.0±0.23 in the male control subjects. It was 4.1±0.35, 2.9±0.29 and 1.9±0.32 in female that are TB infected and yet to commence drugs, those on drugs and the control subjects respectively. The total mean MDA value for those on tuberculosis drugs was 4.0±0.33, 2.8±0.46 for those that are yet to commence the treatment and 2.0±0.28 for the control subjects, the serum levels of SOD was found significantly lower (p<0.005) in PTB subjects on treatment compared to those without treatment and control subjects. Conclusively, the findings of the current study showed that pulmonary tuberculosis patients are predisposed to oxidative stress leading to an increased MDA and consequent decreased SOD levels as compared to the control subjects.

Background: One of the most common complications of pregnant women is gestational diabetes mellitus (GDM). Oxidative stress can play an important role in GDM. Objective: The aim of this study was to evaluate salivary antioxidants and oxidative stress markers in GDM. Method: Twenty pregnant women with GDM and 20 healthy pregnant women with normal blood glucose test participated in this study. Five mL of unstimulated saliva samples were collected. Spectrophotometric assay was carried out for sialochemical analysis. Stata software was used for data analysis. Results: The GDM group exhibited no significant difference in salivary total antioxidant capacity and malondialdehyde compared to the healthy control group. All of antioxidants markers, the uric acid, total antioxidant, peroxidase and catalase, decreased in GDM group that the difference of peroxidase and catalase was statistically significant. All of oxidative stress markers, the salivary malondyaldehid, total oxidative stress and total thiol, increased in GDM group. GDM group exhibited significantly higher salivary total oxidative stress levels. Conclusion: Catalase level was significantly lower and total oxidative stress was significantly higher. These two markers might have significant importance and might exhibit early changes compared to other factors in GDM. . Some of salivary antioxidants might have diagnostic, prognostic or therapeutic implications in GDM. Other studies with large sample size on salivary and blood samples need to be done to confirm this properties and salivary samples using instead of blood samples in GDM biomarkers changes.

Background: Diabetes Mellitus (DM) is a progressive metabolic disorder. Objective: The aim of this study was to investigate the relationship between antioxidant and oxidative stress markers in the saliva of patients with type 2 DM and a healthy control group. Methods: In this study, 20 patients with diabetes and 20 healthy individuals were evaluated. Salivary antioxidants markers consisted of total antioxidant capacity (TAC), uric acid (UA), peroxidase and catalase. Oxidative stress markers included total oxidant status (TOS), malondealdehyde (MDA) and total thiol (SH). Sialochemical analysis was performed with spectrophotometric assay. All the statistical analyses were conducted using STATA software. Results: TAC decreased significantly in patients with diabetes. Although salivary UA and peroxidase were lower in patients with diabetes compared to the control group, the difference was not significant. Salivary catalase in patients with diabetes was significantly lower than that in the control group. MDA and TOS exhibited significantly higher levels in type 2 DM. SH levels were slightly higher in DM. Conclusions: According to the results of the present study, there were some changes in the salivary levels of some antioxidants and oxidative stress markers in patients with type 2 DM and could be measured as an indicator of serum changes..

Background: Most studies on oxidative stress markers and antioxidant levels have been conducted in male athletes, although female participation in sport has increased rapidly in the past few decades. In particular, it could be important to assess oxidative stress markers in relation to the training load because the anaerobic path becomes predominant in high-intensity actions. Methods: Ten female professional basketball players, performing five 2 h-lasting training sessions per week, and 10 sedentary control women were investigated. Capillary blood and saliva samples were collected in the morning before the training session. The antioxidant capacity and the levels of reactive oxygen metabolites on plasma were determined measuring Reactive Oxygen Metabolite and Biological Antioxidant Potential (d-ROMs and the BAP Test). Salivary cortisol was detected by using commercial enzyme-linked immunosorbent assay kit. Results: The antioxidant capacity (BAP value) was significantly higher in elite basketball players (21.2%; p < 0.05). Conversely, cortisol (51%; p < 0.009) and the levels of oxidative species (d-ROM, 21.9%; p < 0.05) showed a significant decrease in elite athletes.
