The management of menopause with complementary and alternative medicine using an experimental model: ovariectomized rats.

AIM: The purpose of this research was to assess the effects of the flower essences She Oak and Bush Fuchsia on behavioral anxiety in ovariectomized (OVX) rats. METHODS: For four weeks, OVX rats received the flower essences She Oak, Bush Fuchsia or a combination of the two. After flower therapy, the animals were subjected to an elevated plus maze (EPM) behavioral anxiety-test. Cortisol blood level was also evaluated. RESULTS: OVX rats treated with the flower essence She Oak became less anxious and had more entries in the EPM open arms. On the other hand, OVX rats treated with the Bush Fuchsia essence spent more time in the EPM closed arms. This finding is similar to those obtained with controls. In addition, OVX rats that received She Oak and Bush Fuchsia in combination presented the same results as those receiving the Bush Fuchsia alone. CONCLUSIONS: Our results suggest that the flower essence She Oak could have an anxiolytic effect in OVX rats, but that the combination therapy of the She Oak and Bush Fuchsia could avoid the effects of the She Oak.

Plasma levels of E-cadherin and MMP-13 in prostate cancer patients: correlation with PSA, testosterone and pathological parameters.

AIMS AND BACKGROUND: Prostate cancer is the most common malignant tumor in men. Serum prostate-specific antigen (PSA), Gleason score and clinical range at the time of diagnosis are important factors to predict prognosis and outcome after therapy but additional accurate and reliable biomarkers are still wanted. So far, few biomarkers of prostate cancer have been successfully implemented and are being used in clinical practice. However, modifications of E-cadherin and MMP-13 expression are likely to be involved in prostate cancer invasion and thus are potential biomarkers for prognosis. PATIENTS AND METHODS: We analyzed the concentrations of E-cadherin and MMP-13 in plasma of patients with prostate cancer at diagnosis and 3 and 6 months after the beginning of treatment and related these measures to free and total PSA and other clinical features. RESULTS: The concentration of E-cadherin was lower in patients with prostate cancer compared to the control group, but there was no difference in the concentration of MMP-13 between these two groups. During treatment, however, we found no significant differences between the concentrations of MMP-13 and E-cadherin, but we observed a significant positive correlation between total PSA and E-cadherin plasma concentration at the third month of treatment and between total testosterone and MMP-13 plasma concentration before the start of treatment. CONCLUSIONS: The results suggest that these parameters could be used both in the diagnosis and prognosis of prostate cancer.
