    Objective
    Rose oil is obtained from the petals of difference Rosa species especially Rosa centifolia L. and Rosa damascena Mill. Various pharmacological properties have been attributed to rose oil. The aim of the present study was to review the rose oil therapeutic effects which had been clinically evaluated in trial studies.
    Materials And Methods
    Google scholar, PubMed, Cochrane Library, and Scopus were searched for human studies which have evaluated the therapeutic effects of rose oil and published in English language until August 2015.
    Results
    Thirteen clinical trials (772 participants) were included in this review. Rose oil was administered via inhalation or used topically. Most of the studies (five trials) evaluated the analgesic effect of rose oil. Five studies evaluated the physiological relaxation effect of rose oil. Anti-depressant, psychological relaxation, improving sexual dysfunction, and anti-anxiety effects were the other clinical properties reported for rose oil.
    Conclusion
    Numerous studies on the pharmacological properties of rose oil have been done in animals, but studies in humans are few. In this study, it was observed that rose oil had physiological and psychological relaxation, analgesic and anti-anxiety effects. To obtain conclusive results on the efficacy and safety of rose oil, further clinical trials with larger sample size and better designation are required.

    Objective
    Allium elburzense is an endemic plant of the family Amaryllidaceae that grows wild in northern Iran with some nutritional and medicinal applications. The present study was aimed to investigate the fibrinolytic and antioxidant effects of A. elburzense bulb extracts.
    Materials And Methods
    Hydroalcoholic, aqueous, chloroformic and butanolic extracts were evaluated in this research. In vitro antioxidant assays were performed using total phenolic, DPPH, and FRAP methods. In the in vivo analysis, animals receivedi.p. injection of A. elburzense hydroalcoholic extract for 21 days and hydroperoxides level, FRAP value, PT and aPTT were determined in serum samples. The fibrinolytic activity of different extracts was quantitatively evaluated by measurement of clot weight.
    Results
    In vitro antioxidant assay showed that A. elburzense aqueous extract had the highest DPPH scavenging and the highest total antioxidant capacity. In the in vivo assay, A. elburzense hydroalcoholic extract reduced serum hydroperoxides level and increased serum total antioxidant capacity in rats.In vitro fibrinolytic assay revealed remarkable thrombolytic activity for this plant with the highest effect for the aqueous extract. However, coagulation parameters including PT and aPTT were not affected by administration of A. elburzense hydroalcoholic extract in rats.
    Conclusion
    In conclusion, the results of this study revealed the potential antioxidant and fibrinolytic effects of A. elburzense bulbextracts. For developing novel thrombolytic agents, further investigations for isolation of bioactive constituents and finding the underlying mechanisms are suggested.

    Objective
    This study examines the effect of the addition of IMOD, a novel multi-herbal drug to the highly active anti-retroviral therapy (HAART) regimen, on the immunological status of HIV-positive patients.
    Materials And Methods
    A randomized two-parallel-group (HAART group versus HAART⃃ group), pretest-posttest design was used.
    Sixty patients with indications for treatment with the HAART regimen participated. One week before and 2 days after the treatments, immunological parameters including total lymphocyte count (TLC) and CD4 cell count were assessed.
    The intervention group received the HAART regimen plus IMOD every day for 3 months. The control group received only the HAART regimen every day for 3 months.
    Results
    In the intervention group, a significant difference was observed in CD4between before and after drug therapy (CD4 was increased). However, in the control group, the difference in CD4 was not significant before and after drug therapy. The difference in TLC was not significantly different between the two groups before and after therapy. Nevertheless, TLC was higher in the intervention group.
    Conclusion
    IMOD (as a herbal drug) has been successfully added to the HAART regimen to improve the immunological status of HIV-positive patients.

    Objective
    The effect of linalool, a terpene alcohol found in many plants, which inhibits NMDA receptors, on the acquisition and reinstatement of morphine-induced conditioned place preference (CPP) was evaluated in mice.
    Material and
    Methods
    The effects of different doses of linalool (12.5, 25 and 50 mg/kg, i.p.), memantine (20 mg/kg, an NMDA receptor antagonist) and saline, in CPP induced by 40 mg/kg of morphine were investigated in mice. In another experiment, a single injection of morphine (10 mg/kg) reinstated the place reference following extinction of a place preference induced by morphine (40 mg/kg). Linalool (12.5, 25 and 50 mg/kg, i.p.), memantine (20 mg/kg) and saline were administrated 30 min before this priming dose of morphine.
    Results
    In the first experiment, linalool (12.5 and 50 mg/kg) was able to decrease morphine-induced CPP. In the second part, linalool (25 and 50 mg/kg) reduced morphine-induced reinstatement of place preference. Both acquisition and reinstatement of morphine-induced CPP, were considerably decreased by memantine.
    Conclusion
    The present study showed that linalool is able to reduce the acquisition and reinstatement of morphine-induced CPP which might be due tothrough NMDA receptors blocking.

    Objective
    Antioxidant, anti-inflammatory, analgesic and antimicrobial activities of Tribulus terrestris (T. terrestris) could be helpful in the treatment of acute pancreatitis; thus, this study was designed to investigate the effects of T. terrestris on cerulein-induced acute pancreatitis in mice.
    Materials And Methods
    Three doses (100, 200 and 400 mg/kg) of T. terrestris hydro-alcoholic extract were administered both orally (60 minutes before pancreatitis induction, p.o.) and intra-peritoneally (30 minutes before pancreatitis induction, i.p.) to different groups of mice (n=6). Pancreatitis was induced by five injections (i.p.) of cerulein 50μg/kg body weight with 1 hr intervals. Animals were euthanized 5 hr after the last injection of cerulein and tissue injures were assessed biochemically and pathologically.
    Results
    T. terrestris extract 200 and 400mg/kg (p.o.) and T. terrestris extract 400 mg/kg (i.p.) reduced pancreatic tissue myeloperoxidase (MPO) activity and serum amylase and lipase levels and alleviated histological parameters.
    Conclusion
    These data suggest that T. terrestris hydro-alcoholic extract was effective in protecting against experimental acute pancreatitis and possibly the efficacy depends on dose and route of administration.

    Objective
    Postmenopausal osteoporosis is characterized by increased fracture risk. However, each approved treatment has specific side effects. Therefore, foods with plant origins have increasingly attracted attention as an alternative treatment. Studies have shown that Elaeagnus angustifolia (EA) has antioxidant properties. The present study aimed to investigate the effects of EA hydroalcoholic extract on ovariectomy-induced osteoporosis in rats using stereological methods.
    Material and
    Methods
    55 female Sprague-Dawley rats were randomly assigned to control, sham operated (normal saline), ovariectomized (OVX), OVX EA fruit extract (600 mg/kg BW/day), and OVX estradiol benzoate (3 mg/kg BW) for 16 weeks. Blood samples were collected to measure calcium, phosphorus, and alkaline phosphatase (ALP) plasma levels. Then, specimens from tibia and fifth lumbar vertebra (L5) bones were prepared and stereological analysis was done.
    Results
    Ovariectomy significantly decreased the calcium level and increased the ALP level in the OVX group. In spite of improvement in calcium hemostasis in groups treated with estrogen and EA fruit extract (p
    Conclusion
    The results showed that EA extract exerted more effects, markedly, on osteoblastogenesis in the OVX rats. Thus, it could be considered as a potential agent to treat patients with osteoporosis.
