RESUMEN
Antiinflammatory and immunomodulatory benefit of green tea (Camellia sinensis) in autoimmune disease has been proven in recent studies. The objective of this study was to assess the effects of green tea on disease activity and quality of life in systemic lupus erythematosus patients. A randomized controlled trial on subjects with lupus was conducted, and 68 patients in the age range of 39.1 ± 10.3 years and body mass index of 25.7 ± 5.21 kg/m2 completed the 12-week study. Patients were randomly divided into two groups of intervention (1000 mg green tea extract, two capsules/day) and control (1000 mg of starch, two capsules/day). Main outcome measure, systemic lupus erythematosus disease activity, was assessed by the systemic lupus erythematosus disease activity index at the first and after 3 months of intervention. In addition, patient's quality of life was evaluated by short form of quality-of-life questionnaire at baseline and after 3 months. Green tea extract supplementation significantly reduced disease activity in lupus patients (p < 0.004); in addition, it significantly increased the vitality (p < 0.006) and general health (p < 0.01). This study showed that daily consumption of green tea extracts for 12 weeks improves the systemic lupus erythematosus disease activity as well as some aspects of quality of life.

BACKGROUND: Candida albicans may cause vaginal infections in women. The aim of this study was to compare the antifungal effect of Lawsonia inermis with that of clotrimazole on rats. METHODS: A total of 35female Wistar rats were randomly assigned into 5groups. Four groups were infected vaginally with C. albicans and one group was not (negative control). The four infected groups received the following treatments: two groups received vaginal creams of 2% or 4% of L. inermis, one group received 1% clotrimazole and one infected group did not receive any treatment (positive control). The hydro-ethanolic henna extract was prepared from the powder of henna leaves using maceration method. Samples were taken for culture from the vaginae of all rats before the treatment, one and two weeks after treatment. An ANOVA test was used to analyze the data. RESULTS: Before the treatment, the mean colony forming units (CFU) was 213.6±10.08 and 334.42±20.32 in the 2% and 4% henna groups, respectively, 312.7±28.32 in the clotrimazole group, 233.85±8.15 in the positive control group, and zero in the negative control group. The mean CFUs were zero for all groups except for the 2% henna and positive control groups (P<0.001) one week after the treatment and zero in all groups except for the positive control group two weeks after the treatment (P<0.001). CONCLUSION: L. inermis (henna) in form of vaginal cream could treat C. albicans infections in female rats; however, 4% henna was more effective and had an effect similar to that of clotrimazole.
