RESUMO

Crataegus oxyacantha is used in the treatment of cardiovascular diseases. The aim of this study was to evaluate the transplacental genotoxicity effect of aqueous (AE) and hydroalcoholic extract (HE) of leaves C. oxyacantha in a rat model and the quantification of malondialdehyde (MDA) in the liver. Three different doses of the AE and HE of the C. oxyacantha leaf were administered orally (500, 1000 and 2000 mg/kg) to Wistar rats during 5 days through the pregnancy term (16-21 days), and sampling in rats occurred every 24 h during the last 6 days of gestation, while only one sample was taken in neonates at birth. A sample of the mother's and the neonate's liver was taken for the determination of MDA. The results show that, at the hepatic level, the evaluated doses of extracts C. oxyacantha in pregnant rats and their pups did not show cytotoxicity. However, the AE and HE generated cytotoxic and genotoxic damage in the short term. On the other hand, only the AE showed a teratogenic effect. Based on these results, the AE and HE of the C. oxyacantha leaf should not be administered during pregnancy.

RESUMO

Genomic instability is associated with increased oxidative stress in patients with human immunodeficiency virus (HIV). The aim of this study was to determine the effect of intake of methanolic and aqueous extracts of Rosmarinus officinalis on genomic instability in HIV patients. We studied 67 HIV patients under pharmacological treatment with ATRIPLA who were divided into three groups: group 1, patients under ATRIPLA antiretroviral therapy; group 2, patients with ATRIPLA and rosemary aqueous extract (4 g/L per day); and group 3, patients with ATRIPLA and rosemary methanolic extract (400 mg/day). The genomic instability was evaluated through the buccal micronucleus cytome assay. Oral epithelial cells were taken at the beginning and 1 and 4 months later. The groups that received the pharmacological therapy with ATRIPLA and the complementary therapy with R. officinalis extracts showed a decrease in the number of cells with micronuclei and nuclear abnormalities compared with the group that only received ATRIPLA. The complementary therapy with R. officinalis decreased the genomic instability in HIV patients.

RESUMO

BACKGROUND: Rosemary leaves powder has been reported to reduce in a dose-dependent manner, glucose levels, lipid profile and lipid peroxidation in humans. However, patients should ingest high doses of powder contained in capsules. This formulation constitutes the intake of 10 capsules per day, so the active metabolite must first, be released and then absorbed (for which, rosemary leaf powder must be mixed with gastric juice). AIM: Evaluate whether a shortened dose and time of treatment as well as the pharmaceutical presentation in rosemary tea (Rosmarinus officinalis) instead of powder have a therapeutic effect in the treatment of T2D. METHOD: The complementary therapy with Rosemary tea (2g/1 litre of water per day) were evaluate on resistance to insulin, oxidative stress, biochemical parameters and anthropometric measurements in forty patients T2D under treatment with metformin and/or glibenclamide afther giving your authorization through informed consent. RESULTS: The data indicated that Rosemary tea intake after 90 days, statistically decreased (p < 0.05) anthropometric parameters like the body mass index and waist-hip ratio. Remarkably, this treatment decreased the percentages of glycated hemoglobin, insulin resistance, and the pancreatic ß-cell function and lastly, a significant difference in lipid peroxide levels was found. CONCLUSION: These data show that shortening time and dose, as well as changing the formulation of the Rosemary plant constitutes a promising treatment for drug-resistant T2D patients.
