Aim. This study was aimed at evaluating prooxidant-antioxidant balance (PAB) in patients with systemic lupus erythematosus (SLE) and its relationship with laboratory findings and clinical manifestations. Methods. In this case-control study, 60 patients with SLE and 60 healthy individuals were enrolled. The blood samples were collected and their sera were separated. Subsequently, the prooxidant-antioxidant balance value was evaluated using PAB assay for each sample. Results. The mean of PAB values in SLE patients was significantly higher than healthy controls (147.3 ± 42 versus 84.8 ± 32.2 HK, P < 0.0001). Furthermore, in SLE patients, there was a positive significant correlation between the PAB and erythrocyte sedimentation rate (ESR) (r = 0.492, P < 0.001). In addition, the PAB values in patients with alopecia, discoid rash, oral ulcers, arthritis, and nephritis were significantly higher than those without these manifestations. Conclusion. The findings of current study showed that the mean of PAB was significantly higher in SLE patients and PAB was correlated with ESR. Moreover increased PAB was found in SLE patients with alopecia, discoid rash, oral ulcers, arthritis, and nephritis. These findings suggest that the measurement of PAB may be useful to show oxidative stress condition in SLE patients.

Cutaneous leishmaniasis is one of the important skin diseases with diverse clinical manifestations. With an incidence of 0.7-1.3 million cases annually, this disease is often reported from six countries, including Iran. Accordingly, the purpose of this study was to evaluate the antileishmanial effect of the three plant hydroalcoholic extracts including fleawort (Plantago psyllium L.), savory (Satureja hortensis L.) and tarragon (Artemisia dracunculus L.) on Leishmania major promastigotes. The hydroalcoholic extract from each plant was extracted and its anti-leishmanial effect was evaluated in different concentrations (100-1000 lg/ml) and at various hours (24, 48 and 72 h). Savory herb inhibitory concentration 50 % (IC 50 ) at 24, 48 and 72 h was 790.81, 398.11 and 298.42 lg/ml, respectively. In addition, tarragon herb IC 50 at 24, 48 and 72 h was 962.03, 688.36 and 585.51 lg/ml, respectively. Moreover, the fleawort extract was showed the lowest effect, considering that its effect at the concentration of 1000 lg/ml was 48 % after 72 h (P [ 0.05). Furthermore, the statistical analysis showed a significant difference for interaction between concentration and time regarding the tarragon and savory extracts with a P value of lower than 0.05. According to the results, the anti-leishmanial effect of the tarragon and savory extracts may make it possible to use them in the treatment of cutaneous leishmaniasis as a complementary or alternative therapy; however, further studies are necessary and should be evaluated in cell culture and in vivo conditions to confirm it.
