Decreased dysmenorrhea pain in girls by reducing oxidative stress and inflammatory biomarkers following supplementation with oleoylethanolamide: A randomized controlled trial.

AIM: This study aimed to evaluate the oleoylethanolamide (OEA) effects on oxidative stress and inflammatory factors in girls with primary dysmenorrhea. METHODS: This double-blind, placebo-controlled clinical trial was done on population consisted of female students who had dysmenorrhea pain based on the visual analogue scale (VAS) questionnaire. Patients were randomly allocated to groups consuming a capsule containing 125 mg of OEA per day (n = 22) or placebo (n = 22) for 2 months. The severity of the pain, total antioxidant capacity (TAC), malondialdehyde (MDA), C-reactive protein (CRP), and tumor necrosis factor alpha (TNF-α) were measured at the beginning and the end of the study. In this study, SPSS software was used to analyze the data. RESULTS: According to the results, oral supplementation with OEA for 60 days significantly increased TAC (p = 0.022) and decreased the menstrual pain (p = 0.040), MDA (p = 0.011), CRP (p = 0.01), and TNF-α (p = 0.038) compared to the placebo group. Also, intragroup changes were statistically significant on the mean of pain (p = 0.042), TAC (p = 0.032), MDA (p = 0.023), CRP (p = 0.027), and TNF-α (p = 0.029) at the end of the study in the intervention group. Changes in the studied factors at the end of the study compared to the beginning of the study in the placebo group were not statistically significant. CONCLUSION: Considering the reducing effects of OEA on menstrual pain, using of this supplement can be introduced as an alternative medicine to reduce the use of anti-inflammatory drugs.

Randomized double blind clinical trial evaluating the Ellagic acid effects on insulin resistance, oxidative stress and sex hormones levels in women with polycystic ovarian syndrome.

OBJECTIVE: The design of this study was due to the report of the antioxidant properties of Ellagic acid (EA) for its evaluation on the Insulin resistance (IR), oxidative stress and sex hormones levels in women with polycystic ovarian syndrome (PCOS). METHODS: In this randomized, double-blind, placebo-controlled clinical trial, 60 patients were recruited. Patients were randomly allocated consumed a capsule containing 200 mg of EA per day (n = 30) or placebo (n = 30) for 8 weeks. The fasting blood sugar (FBS), insulin, IR, total cholesterol (TC), triglycerides (TG), low density lipoprotein (LDL), high density lipoprotein (HDL), total antioxidant capacity (TAC), Malondialdehyde (MDA), C-reactive protein (CRP), Tumor necrosis factor-alpha (TNF-α), sex hormones and anti-mullerian hormone (AMH) were measured at the beginning and end of the study. RESULT: At the end of the study, the mean of FBS, insulin, IR, TC, TG, LDL, MDA, CRP, TNF-α, total testosterone, prolactin and AMH were significantly decreased in the intervention group compared to the placebo group (P < 0.05). Also, there was a significant increase in the mean of TAC after supplementation with EA (P < 0.05). At the end of the study, no significant changes were observed in the mean of anthropometric factors, physical activity and food intake (P > 0.05). CONCLUSION: EA supplementation can be helpful as a diet supplement in women with PCOS through improvement in insulin resistance. This supplement may be used to reduce metabolic disorders in women. TRIAL REGISTRATION: This study was retrospectively (07-07-2019) registered in the Iranian website ( www.irct.ir ) for registration of clinical trials ( IRCT20141025019669N12 ).

Evaluation of the Antimalarial Effect of Ferulago angulata (Schlecht.) Boiss. Extract and Suberosin Epoxide Against Plasmodium berghei in Comparison with Chloroquine Using in-vivo Test.

Resistance to most antimalarial drugs has encouraged the development of novel drugs. An alternative source for discovering such drugs is natural products. Some Ferulago species are used in folk medicine for their sedative, tonic and anti-parasitic effects. Besides, coumarins isolated from this genus found to have in vitro anti-leishmanicidal effect. The present study is aimed to evaluate the in-vivo antimalarial activity of Ferulago angulata (Schlecht.) Boiss. extract and suberosin epoxide, using suarian mice. A rodent malaria parasite, Plasmodium berghei was used to inoculate healthy male Swiss Albino mice of age 6-8 weeks and weight 23-27 g. Hydro-alcoholic extract of F. angulata (20, 100, 300, 600 mg/Kg) and suberosin epoxide suspension (10, 30, 50, 100 mg/Kg) were administered subcutaneously. Parameters including percentage of parasitemia, suppression of parasitemia and mean survival time were determined using standard test such as peterÙ¬s. Chemo-protective effects were exerted by the crude extract and suberosin epoxide. Maximum effect was observed with the larger doses of the crude extract and suberosin epoxide. Suberosin epoxide increased the survival time compared to chloroquine. However, the results of this study indicate that the plant has a promising anti-plasmodial activity against plasmodium berghei. Thus, it could be considered as a potential source of new antimalarial agents. Suberosin epoxide at the dose of 100 mg/Kg possesses relatively significant antimalarial effect. Chemical derivatization of the parent compound or preparation of the modified formulation is required to improve its systemic bioavailability.

An ethnobotanical survey on hormozgan province, Iran.

OBJECTIVE: The present study is based on an ethnobotanical research project conducted in Hormozgan province that is located in south of Iran, bordering waters of the Persian Gulf and Oman Sea. This survey was carried out in order to recover the ethnobotanical and ethnomedicinal knowledge of the residents of this province. They are using medicinal and functional plants for treating or preventing several diseases. MATERIALS AND METHODS: Ethnobotanical data sheets were run with the native inhabitants and people of the province by arranging frequent field trips to different parts of the province and direct interviews with them especially those who were more familiar with the plants and their usage. RESULTS: A total of 150 plant species belonging to 53 families were recorded for their ethnobotanical and ethnomedicinal uses among the people of province. The records were developed by scientific names, family names, local names, medicinal parts used, different ways of their application, and traditional uses of the plants. There was high compliance in the use of plants in painful disorders, gastrointestinal, and dermatological diseases. CONCLUSION: This study revealed that the people of Hormozgan province have a rich knowledge of natural resources. The use and consumption of medicinal plants are still important parts of their life. Rational use of native medicinal plants may benefit and improve their living standards and quality of life. The results of this study can be used as a basis for selecting herbs for further pharmacological, phytochemical, and pharmacognostical studies.
