Efficacy and safety of a soy isoflavone extract in postmenopausal women: A randomized, double-blind, and placebo-controlled study

Objective: To investigate the efficacy of soy isoflavone on climacteric symptoms in postmenopausal women.Design: In this double-blind, randomized, placebo-controlled study, a total of 80 women (mean age =55.1 years), who reported 5 or more hot flush episodes per day, were randomized to receive either 250 mg of standardized soy extract (Glycine max AT) a total of 100 mg/day of isoflavone (n=40) or placebo (n=40). Exclusion criteria included: contra-indication for hormone therapy (HT), chronic gastrointestinal diseases, and users of HT within the preceding 6-months. For 10-months, climacteric symptoms were evaluated using a score card and the menopausal Kupperman index. Compliance and safety were also assessed. At baseline and the end of the study, lipid and hormonal profiles, as well as vaginal, mammographic and ultrasonographic parameters were measured. The t-test, Wilcoxon test and ANOVA were used in the statistical analysis.Results: At baseline, the mean number of hot flushes was 9.6 +/- 3.9 per day in the isoflavone group and 10.1 +/- 4.9 in the placebo group (p>0.05). After 10 months, there was a significant reduction in frequency of hot flushes among isoflavone users when compared to those on placebo (3.1 +/- 2.3 and 5.9 +/- 4.3, respectively) (p<0.001). Kupperman index mean values showed a significant reduction in both groups. However, soy isoflavone was significantly superior to placebo, in reducing hot flush severity (69.9% and 33.7%, respectively) (p<0.001). Endometrial thickness, mammography, vaginal cytology, lipids and hormonal profile did not change in both groups. No serious adverse event related to isoflavone treatment was reported.Conclusions: the soy isoflavone extract exerted favorable effects on vasomotor symptoms and good compliance, providing a safe and effective alternative therapeutic for postmenopausal women.

Efeitos hipotensivo e diurético dos extratos aquosos de pitanga (Eugenia uniflora L.) e jambolão (Eugenia jambolana Lam.) em ratos normotensos anestesiados

Plants that possess a diuretic effect are widely used by people in the treatment of some important diseases as edema and hypertension. The objective of this work was to study the effects of pitanga and jambos aqueous extracts (AE) about the arterial pressure (AP) and urinary flow (V) in normotensive and anesthetized rats. The AE were prepared for the decoction method and administrated for intragastric way in different concentrations: 10%, 15%, 20% and 25%. These concentrations corresponded respectively at doses of 56, 94, 145, 172 mg of pitanga dried extract /Kg and 44, 73, 83, 95 mg of jambos dried extract/Kg. The animals were divided in nine groups with seven individuals (n=7): control (C), P-10%, P-15%, P-20%, P-25%, J-10%, J-15%, J-20% and J-25%. The rats were anesthetized (hypnol 3%) and submitted to tracheotomy. The left carotide artery was catheterized to measure the AP through a mercury manometer, in periods of 15 minutes. The bladder was catheterized for urine collection and to measure the V, in periods of 30 minutes. The experimental protocol was divided in four periods of 30 minutes each: basal (to evaluate of the basal parameters) and experimental (Exp) 1, 2 and 3 (after the administration of the AE). The results were analyzed for ANOVA and Tukey (X±SD, p<0.05). In the C group did have not alteration of the AP basal but the V basal increased. In the experimental groups (AE of P and J) had significative decline in the AP basal: 34% (P-10%), 20% (P-15%), 21% (P-20%), 31% (P-25%), 24% (J-10%), 20% (J-15%) 16% (J-20%) and 29% (J-25%). Moreover, the administration of AE increased the V basal in: 280% (P-15%) and 192% (J-20%). The results showed that the plants evaluated are hypotensive and diuretic.

Effects of soy isoflavones on mammographic density and breast parenchyma in postmenopausal women: A randomized, double-blind, placebo-controlled clinical trial

OBJECTIVE: This study aims to evaluate the effects of soy isoflavones on breast tissue in postmenopausal women. METHODS: In this randomized, double-blind, placebo-controlled study, 80 women (aged ≥45 y and with amenorrhea >12 mo) with vasomotor symptoms were randomized to receive either 250 mg of standardized soy extract corresponding to isoflavone 100 mg/day (n = 40) or placebo (n = 40) for 10 months. Breasts were evaluated through mammographic density and breast parenchyma using ultrasound (US) at baseline and 10-month follow-up. Independent t test, analysis of variance, Mann-Whitney U test, and χ2 trend test were used in statistical analysis. RESULTS: Baseline clinical characteristics showed no significant differences between the isoflavone group and the placebo group, with mean (SD) age of 55.1 (6.0) and 56.2 (7.7) years, mean (SD) menopause duration of 6.6 (4.8) and 7.1 (4.2) years, and mean (SD) body mass index of 29.7 (5.0) and 28.5 (4.9) kg/m2, respectively (P > 0.05). The study was completed by 32 women on isoflavone and 34 women on placebo. The groups did not differ in mammographic density or breast parenchyma by US (P > 0.05). Within each group, the baseline and final moments did not differ in mammography or US parameters significantly (P > 0.05). CONCLUSIONS: The use of soy isoflavone extract for 10 months does not affect breast density, as assessed by mammography and US, in postmenopausal women. © 2013 by The North American Menopause Society.

Effect of rosemary (Rosmarinus officinalis) extracts on the oxidative stability and sensory acceptability of soybean oil

Background: Plant extracts have b een used as an alternative to the use of synthetic antioxidants in order to preserve oils fromoxidative degradation. Additionally, these extracts add special flavors and aromas to the food. Thus, the objective of this studywas to evaluate the effect of hydroethanolic extracts of fresh and freeze-dried rosemar y in the oxidative stability of soybean oilunder accelerated storage in an oven. Results: The application of the extracts in the oil showed that that freeze-dried extract was better in reducing the formation ofoxidation products, showing 8.6 meq kg−1of peroxides after 20 days of storage. On the other hand, the mixture of the naturalextract with t-butylhydroquinone conferred better oxidative stability index until the 20th day, 9.7 h. Both extracts prevented theloss of tocopherol, not d iffering between each other (P > 0.05), and present approximately 505 mg kg−1of residual tocopherols.The sensory evaluation revealed that consumers accepted equally the oils added and not added of the rosemary extracts. Conclusion: The extracts are therefore potential sources of natural antioxidants and they would be well accepted by consumersif applied by the food industry to replace synthetic antioxidants.

Extratos secos padronizados: tendência atual em Fitoterapia

Data shows that the use of the medicinal plants in industrialized countries represents around 20% of the total medical prescriptions. Considering the need to establish a safe phytotherapic practice, specially when the evidence based medicine is a current tendency, phytotherapic medicines can no longer justify any doubts regarding its safety and efficacy. So, proof of efficacy and safety must result preferably from properly conducted clinical trials, although the legislation exempts such studies for traditional or well established phytotherapics. In this article, benefits and advantages of standardized dry extracts used in phytotherapic medicines instead of powder drugs and dry extracts are analyzed and discussed. The study reveals as main conclusive remark, that adequate clinical trials are essential to promote this therapeutical practice.
