Medicinal Plants Used in Iranian Traditional Medicine (ITM) as Contraceptive Agents.

BACKGROUND: In recent years, rapid population growth and unsafe abortions have emerged as controversial health issues in some countries. Hence, safe and effective contraceptive methods or agents have attracted a great deal of attention and the corresponding market has been widely expanded. OBJECTIVE: In this study, we present a review profiting from Iranian Traditional Medicine (ITM) to introduce expedient plants as efficient contraceptive agents. METHODS: Medicinal plants suggested as contraceptive agents were obtained from ITM text books and they were also investigated using search engines to confirm their in vitro and in vivo efficacy. RESULTS: According to credible Iranian medical literature a wide spectrum of plants possesses contraceptive activity and among them, Ruta graveolens, Ricinus communis, Piper nigrum, and Physalis alkekengi were found to be more efficient. CONCLUSION: Complementary and Alternative Medicine (CAM), particularly herbal remedies have received a lot of attention because of their truly healing properties. Focusing on ITM knowledge, there are various comments based on medicinal plants to reduce unsafe abortions leading to better public health in the society.

Investigation of antioxidant and anti-glycation properties of essential oils from fruits and branchlets of Juniperus oblonga

Plants represent the best and most extensively studied source of natural antioxidants. The present study investigated the antioxidant and anti-glycation properties of different concentrations of essential oils obtained from fruits and branchlets of Juniperus oblonga M. Bieb., Cupressaceae, using different assays. The essential oils were obtained by steam distillation of the branchlets of male tree (BMT), branchlets of female tree (BFT) and fruits of J. oblonga. Compositional analysis of oils was performed using a gas chromatography-mass method. Antioxidant activity was assessed using linoleic acid peroxidation, peroxyl radical mediated hemolysis of red blood cells (RBC) and low-density lipoprotein (LDL) oxidation assays. Anti-glycation properties of oils were evaluated using hemoglobin and insulin glycation assays. Seventeen, eighteen and fifteen compounds were identified in the BMT, BFT and fruit oil, which represented 82.51, 55.69 and 96.89% of the total oils, respectively. α-Pinene was the major component of all three oils. All three oils possessed antioxidant effects against LDL oxidation, linoleic acid peroxidation and peroxyl radical mediated RBC hemolysis. Anti-glycation activities against hemoglobin and insulin glycation were also observed from all tested oils. Overall, there was no unique pattern of dose-dependence for the antioxidant properties of oils in different employed systems. The findings of this study suggest that essential oils from fruits and branchlets of J. oblonga possess antioxidant and anti-glycation properties. Therefore, these oils might be of therapeutic efficacy against diabetes and cardiovascular disease.

A needle free system for cervical lymphatic mapping and sentinel node biopsy in oral squamous cell carcinoma.

The techniques of lymphatic mapping and sentinel node biopsy are finding increasing utility in the management of the loco-regional lymphatics in many areas of oncology. Our unit is currently investigating their feasibility in relation to the management of the clinically node negative neck in oral squamous cell carcinoma. In order to reduce patient discomfort, and to remove the possibility of sharps injury, particularly in the high-risk patient, we report the use of a needle free device for the intra-oral delivery of the radiopharmaceutical. We believe that this is the first report using such a device in the oral cavity for the purpose of lymphoscintigraphy, and that it has significant advantages over the conventional hypodermic needle in certain patient groups.
