Saffron is the dried stigmata of the flowers of saffron (Crocus sativus L., Iridaceae). Saffron has various pharmacological effects and is regarded as a potent drug. Thus research on the biological activities of saffron and its active constituents may have clinical and public health applications. To evaluate the basic and clinical pharmacology of saffron and its active constituents, the English papers in the data bases EMBASE, SCOPUS, MEDLINE, SCIENCE DIRECT, CHEMICAL ABSTRACTS, English and Persian papers in the data base SID and proceedings of the Iranian physiology and pharmacology congresses and Iranian congresses concerning saffron were retrieved by using keywords comprising Crocus sativus, anti-tumor, anti-oxidant, anti-genotoxic, memory, neuroprotective, analgesic, anticonvulsant, opioid dependence, antidepressant, cardiovascular, lipids, respiratory, gastric ulcer, immune system, ocular, antimicrobial and toxicity and their Persian equivalents from 1975 until November 2008. The investigations demonstrate that saffron and its active constituents have anti-tumor, anti-oxidant, anti-genotoxic, memory and learning enhancing, neuroprotective, analgesic and anti-inflammatory, anticonvulsant, opioid abstinence syndrome alleviating, antidepressant, hypotensive, hypolipidemic, insulin resistance reducing, tissues oxygenation enhancing, bronchodilator, antitussive, gastric ulcer preventive, Immune-stimulator, retina protective and antibacterial effects. In view of the existing deficiencies in the conducted researches, further clinical trials, pharmacokinetic and toxicological studies concerning saffron are recommended.

Background: The traditional use of medicinal plants to treat diabetes mellitus after using synthetic oral hypoglycemic agents and insulin is point to search for safer and more effective drugs of plant origin, although study of their mechanism have been continued. Olive tree and its products have important components of a healthy diet because of their phenolic content. Objective: We are interested to investigate the effects of the methanol extraction of Olea europaea leaf on insulin secretory function of pancreatic islets which were isolated freshly from rat. Methods: Plants were extracted with methanol and then powdered through freeze-drying. Islets were isolated from male adult pancreas and cultured overnight, preincubated in glucose 2.8 mM then incubated at 37 ºC in the presence of basal (2.8 mM) and stimulatory (16.7 mM) doses of glucose, with different doses of plants extracted (0.01, 0.05, 0.1, 1 mg/ml), after 30 min incubation the secreted insulin was assayed by ELISA kit. Results: Data indicated that Olea europaea leaf extract at concentration of 0.05 mg/ml plus basal glucose could enhance insulin secretion from isolated pancreatic islets compared to control group which exposed just to basal glucose, significantly (4.2 ± 0.48 vs 10.5 ± 0.29 µg/l) (p<0.05), also compared to other groups. Although it could increase insulin secretion at stimulant glucose level but it was not significant. Conclusion: Olive leaf extract, probably without metabolic transformation, could increase insulin secretion from freshly isolated pancreatic islets of rat at basal glucose level significantly, which point to that its affect might be akin to glucose.

Background: Headache is the most common complaint in patients. In order to alleviate the headache, specialists have recommended different chemical and non-chemical drugs. Acetaminophen is one of the widespread analgesic drugs used for headache relief. On the other hand, tea (Camellia thea Lk.) is the most common drink for the most people world wide. In addition, previous studies indicated that tea’s alkaloids seem to inhibit the acetaminophen metabolism. Objective: The present study aims to assess the effect of tea consumption on effectiveness of acetaminophen. Methods: In order to test the hypothesis, 120 patients suffered from headache referred to the Shaheed Motahari general hospital in Jahrom (Fars province, south of IRAN) were requested to take part in a single blind clinical trial study. 58 patients as the case group have received a glass of tea and after 20 min they had taken a 325 mg acetaminophen tablet. 62 patients as the control group received a glass of warm water and 20 min later had the same drug. Pain intensity was twice measured by a self-report questionnaire. The first one was 15 min before the tea or water consumption and the second, 60 min after receiving the acetaminophen. Results: Results showed that: consumption of tea before taking acetaminophen significantly reduced the pain intensity comparing with the control group. In addition, with respect to sex and age, no significant differences were found between the groups. Conclusion: It can be concluded that consumption of tea before taking acetaminophen may accelerate the analgesic effectiveness of the drug.

Background: The gram-negative bacterium Helicobacter pylori (H. pylori), identified in 1982, is now recognized as the primary etiological factor associated with the development of gastritis and peptic ulcer disease. The growing problem of antibiotic resistance by the organism demands the search for novel compounds from plant based sources. Objective: The present study is aimed at evaluating the anti-Helicobacter pylori activity of 10 Iranian plant extracts on clinical isolates of H. pylori. Methods: Gastric biopsy samples were obtained from patients presenting with gastroduodenal complications. H. pylori was isolated from the specimens following standard microbiology procedures. The disk diffusion method was used to determine the susceptibility of 12 isolates to methanol plant extracts (Fruit and leaves of Melia azedarach, Melia indica and aerial parts of Stachys setifera, Stachys turcomanica, Stachys trinervis, Stachys subaphylla, Stachys byzanthina, Stachys persica, Stachys inflata, Stachys laxa). Results: The plants tested at 8 mg/disc concentration demonstrated anti-Helicobacter pylori activity with zone diameters of inhibition ranging from 12-38 mm. Of these, Stachys setifera (aerial parts), Melia indica (Fruit) and Melia azedarach (leaves) showed the most potent anti -H. pylori activity on the isolates. Conclusion: Due to the rise in antibiotic resistance, new sources of anti-H. pylori drugs are needed. The use of medicinal plants may have potential benefit in eradicating such problems. According to the results of this study, further studies will be necessary to investigate the effects of other plants of Iran against H. pylori infection.

Background: The genus Teucrium (Lamiaceae) is comprised of about 340 species widespread over the world. In the Flora Iranica, this genus is represented by 12 species, of which 3 are endemic. Several Teucrium species are used in Iranian folk medicine as medicinal plant. There is no study on the volatile oil of Teucrium hyrcanicum in the literature. Objective: Investigation and comparison on essential oil constituents of two populations T. hyrcanicum collected from two localities. Methods: The aerial parts of T. hyrcanicum were collected from road of Khalkhal-Asalem and Rostamabad shade dried and then essential oil extracted by means of hydrodistillation and analyzed with GC and GC/MS. Results: The essential oil yields were 0.25 and 0.20 (w/w) based on dry weight of plant, respectively. 38 and 15 compounds were idedtified, representing 93.1% and 93.3% of the total oils, respectively. In the oil obtained from Khalkhal-Asalem. Hexahydrofarnesyl acetone (12.7%), linalool (11.7%) and E-β-farnesene (10.7%) were found as the major components. From Rostamabad sample E- β-Farnesene (60.6%) and E-α-Farnesene (15.0 %) were the most abundant. Conclusion: The results showed that the difference in the volatile constituents could be considered as chemotaxonomic significance and it may be attributed to their different ecological and geographical origin factors.

Background: Pain is a sensory modality, which in many cases represents the only symptom for the diagnosis of several diseases. It often has a protective function. Although morphine has reigned for centuries as the king of painkillers, its rule hasn’t been totally benign. There are concerns about its addictive properties and side effects, which include respiratory depression, drowsiness, decreased gastrointestinal motility, nausea and several alterations of the endocrine and autonomic nervous systems. Since Salvia officinalis (sage) is used traditionally in the treatment of painful illnesses, it became worthwhile to evaluate its antinociceptive activities in mice. Objective: The objective of the present work is to evaluate the analgesic activity of essential oil of sage leaves by the formalin test in mice. Methods: The interaction between the plant leaves and opioidergic system on formalin-induced pain were carried out. The essential oil (0.2, 0.25 and 0.3 ml/kg) was injected intraperitoneally. The control groups were administered sunflower oil as vehicles of essential oil. Also, the LD50 of the essential oil of the plant was measured. Results: The results showed that the essential oil of the plant (0.3 ml/kg) decreased both phases of pain. Also, the antinociceptive effect of essential oil (0.3 ml/kg) and morphine (0.5 ml/kg body wt.) were reversed by pretreatment with naloxone (0.5 ml/kg). The LD50 of the essential oil was found 0.5 ml/kg, i.p. Conclusion: The potent analgesic effects were blocked by naloxone, indicating that the analgesic effects are associated with the activation of opioid receptors in the central nervous system. The present data indicate that the plant has analgesic effects on mice and the plant should be considered in future therapeutic researches.
