Iridoid and Furanolabdane -Type Diterpene Glycosides from Rhizomes of Eremostachys azerbaijanica Rech. f.

Background and objectives: The rhizomes of Eremostachys azerbaijanica Rech. f.,as an indigenous plant in East Azerbaijan province of Iran, were studied for isolation and identification of possible phytoconstituents. Methods: The air- dried and ground rhizomes were extracted with n-hexane, dichloromethane (DCM) and methanol (MeOH) using a Soxhlet apparatus. The 10%, 20% and 80% MeOH in water C18 cartridge solid phase extraction products )Sep-Pak fractions( of the MeOH extract were subjected to preparative reversed- phase high performance liquid chromatography (RP-HPLC) and the isolated pure compounds were identified by one- dimensional nuclear magnetic resonance (1D-NMR) spectroscopic technique. Results: The spectroscopic data of the compounds were compared with the respective published data and the obtained results showed the presence of four pure components, 6 - Hydroxy loganin (1), Shanzhiside methyl ester (2), Eremostachiin (β-D-glucopyranosyl-(1→2)-β-D-glucopyranosyl ester of phlomisoic acid) (3) and  Phlomisoside II (4), with iridoid and furano labdane- type diterpene glycoside structures. Conclusion: The occurrence of these types of chemical structures might be a confirmation to close relation and similar pharmacological and biological activities between Eremostachys and Phlomis genera

GC-MS Analysis, Antioxidant and Antimicrobial Screening of Volatile Oil of Lepidium vesicarium

Background: Lepidium vesicarium (Cruciferae), one of the important medicinal plants with a long history of medicinal use. The current study was designed to evaluate the free radical scavenging and antimicrobial activities of the L. vesicarium EO as one of the Iranian plant species. Methods: The compositions of the EO from the aerial parts of L. vesicarium were analyzed by GC-MS and GC-FID. Furthermore, anti-oxidant and anti-microbial potentials were investigated via DPPH reagent and disk diffusion procedure, respectively. Results: A total of 18 compounds amounting 97.70% of the oil have been identified, while Benzyl cyanide (43.94%), Isothio cyanic acid (22.69%) and Benzyl isothio cyanate (20.69%) were the main constituents. The EO showed no activity against the free radicals and studied microbial strains (gram positive and gram negative and also fungi species). Conclusion: On the whole, the presence of cyanide derivatives in studied EO revealed the rational use of this plant in medicine. Comparing with other genesis of Lepidium, anti-oxidant and anti -microbial properties of L. vesicarium essential oil were not noticeable

Wound healing Benefits of Curcumin for Perineal Repair after Episiotomy: Results of an Iranian Randomized Controlled Trial

Pain and discomfort related to episiotomy have been reported to interfere with women's daily activities postpartum, such as sitting, walking and lifting the baby. To compare the effects of curcumin and Povidone-iodine solutions for episiotomy healing in primiparous women. 120 healthy primiparous women with a vaginal delivery at term were evaluated in this double-blind randomized clinical trial. Randomization was done using a table of random list numbers. Perineal healing was evaluated by research midwives blinded to random allocation at 24-48 hours and 10 days postpartum. Pain was assessed via a visual analogue scale and wound healing via the REEDA scale. Analysis was done on the intention-to-treat principle. The main outcome measure was the changes in wound healing between the two groups as measured by the REEDA Scale. Secondary outcome measures were perineal pain and wound healing 24-48 hours and 10 days after delivery. There was a greater decrease in the total scores of the REEDA in the curcumin group than in the Povidone-iodine (P < 0.001), however; there weren't significant differences between the groups on the VAS scores. The application of curcumin may assist in the episiotomy healing process and could be suitable replacement for Povidone-iodine.

Evaluation of the Effect of Aerial Parts of Scrophularia atropatana Grossh Total Extracts on Analgesic Activity and Morphine Induced Tolerance in Mice

Background: Scrophularia atropatana contains chemicals activating the GABA system and inhibiting glutaminergic system. As well as we know, drugs inhibiting glutamate system have analgesic effects and reduce tolerance to the analgesic effects of morphine. In the present study, effect of methanol extract of aerial parts of S. atropatana on tolerance to the analgesic effects of morphine was evaluated. Methods: The aerial parts of S. atropatana were extracted with methanol by maceration and was further analyzed to determine the content of total phenols, antioxidant activity (DPPH method) and analgesic activity. Several groups of mice received drug regimens for 4 days. Group I: Saline (10 ml/kg, i.p.) + Saline (10 ml/kg, i.p.), group II: Morphine (50mg/kg, i.p.) + Saline (10mg/kg, i.p.) and group III: Morphine (50mg/kg, i.p.) + Extract of S. atropatana (100, 200, 400 mg/kg, i.p.)]. On the fifth day the test dose of morphine (9 mg/kg, i.p.) in different groups were assessed. By using hot plate test, the analgesic activity of different doses of the extract was evaluated. Results: Phytochemical screening indicated the presence of total phenolics content of the extract (152 mg GAE/g) and antioxidant activity (RC50 =143µg/ml) in DPPH method. All doses of the extract had analgesic activity. It was found that treatment with extract (100, 200 mg/kg, i.p.) attenuated the development of tolerance to the antinociceptive effect of morphine. Conclusion: The results of the study demonstrate that S. atropatana strongly reduced tolerance to morphine and has analgesic effects. The suggested analgesic effects may be related to the phenolics content and antioxidant activity of the plant alongside inhibition of glutaminergic system

Effect of peppermint water on prevention of nipple cracks in lactating primiparous women: a randomized controlled trial

BACKGROUND: Nipple pain and damage in breastfeeding mothers are common causes of premature breastfeeding cessation. Peppermint water is popularly used for the prevention of nipple cracks in the North West of Iran. The aim of this study was to determine the effectiveness of peppermint water in the prevention of nipple cracks during breastfeeding in comparison with the application of expressed breast milk (EBM). METHODS: One hundred and ninety-six primiparous breastfeeding women who gave birth between February and May 2005 in a teaching hospital in Tabriz, Iran, were randomized to receive either peppermint water or EBM. Each woman was followed for up to three visits or telephone calls within 14 days and then by telephone call at week six postpartum. RESULTS: Women who were randomized to receive peppermint water were less likely to experience nipple and areola cracks (9%) compared to women using EBM (27%; p < 0.01). Women who used the peppermint water on a daily basis were less likely to have a cracked nipple than women who did not use peppermint water (relative risk 3.6, 95%CI: 2.9, 4.3). Nipple pain in the peppermint water group was lower than the expressed breast milk group (OR 5.6, 95% CI: 2.2, 14.6; p < 0.005). CONCLUSION: This study suggests that peppermint water is effective in the prevention of nipple pain and damage. Further studies are needed to assess the usefulness of peppermint water in conjunction with correct breastfeeding techniques. Trial registration number: NCT0045640

Methanolic Extract of Ficus carica

The antiangiogenesis effect of Ficus carica leaves extract in an air pouch model of inflammation was investigated in rat. Inflammation was induced by injection of carrageenan into pouches. After antioxidant capacity and total phenolic content (TPC) investigations, the extract was administered at 5, 25, and 50 mg/pouch, and then the volume of exudates, the cell number, TNFα, PGE2, and VEGF levels were measured. Angiogenesis of granulation tissues was determined by measuring hemoglobin content. Based on the DPPH assay, the extract had significant antioxidant activity with TPC of 11.70 mg GAE/100 g dry sample. In addition, leukocyte accumulation and volume of exudate were significantly inhibited by the extract. Moreover, it significantly decreased the production of TNFα, PGE2, and VEGF, while angiogenesis was significantly inhibited by all administered doses. Interestingly, attenuation of angiogenesis and inflammatory parameters (except leukocyte accumulation) by the extract was similar to that shown by diclofenac. The extract has anti-inflammatory effects and ameliorated cell influx and exudation to the site of the inflammatory response which may be related to the local inhibition of TNFα, PGE2, and VEGF levels as similarly shown by diclofenac. The antiangiogenesis and anti-VEGF effects of Ficus carica may be correlated with its significant antioxidant potentials
