<strong>Objective</strong>: To evaluate wound healing activity of ethanolic extract of Jasminum grandiflorum Linn. (J. grandiflorum) flowers in diabetic rats. <br /> <strong>Materials and Methods</strong>: Streptozotocin-induced diabetic Wistar albino rats were divided into six groups (n=6).Three groups – diabetic control, positive control (that received Glibenclamide) and treatment (that received J. grandiflorum Linn. Flower extract) were operated for excision wounds (EW). These groups were evaluated for wound contraction and re-epithelization. The other three groups were operated for incision wounds (IW) and dead space wounds (DW). Incision and dead space wounds were produced in the same rats. IWs were analyzed for wound breaking strength and the granulation tissues from DWs were analyzed for dry weight, hydroxyproline content, and histology.<br /> <strong>Results</strong>: IWs and DWs showed significant improvement in wound breaking strength (265.8±10.4 vs 332.5±8.2; p<0.05), granulation tissue dry weight (26.1±0.6vs 40.4±0.3; p<0.01) and hydroxyproline content (19.3±0.5 vs 32.6±0.8; p<0.01) in treatment group as compared to control group. Neo-angiogenesis was also high in treatment group. Wound contraction was earlier (day 14) in treatment group compared to diabetic control (day 20). No significant improvement was seen in re-epithelization in treatment group.<br /> <strong>Conclusion</strong>: Ethanolic extract of J. grandiflorum Linn. flowers increases granulation tissue formation as well as neo-angiogenesis. It also enhances wound contraction; however, re-epithelization was not significantly affected. J. grandiflorum Linn. flowers could be potentially effective in promotion of diabetic wounds healing by increasing granulation tissue formation and enhancing wound contraction; however, further studies are required for its clinical application.<br /> .

Objective: Medicinal plants have attracted global attention due to their safety as well as their considerable antioxidant content that helps to prevent or ameliorate various disorders including memory impairments. This study was conducted to investigate the effect of beet root (Beta vulgaris) leaf extract on scopolamine-induced spatial memory impairments in male Wistar rats.<br /> Materials and Methods: Male Wistar rats were randomly divided into 5 groups (n=10): Control (C), scopolamine 1 mg/kg/day (S), scopolamine+50 mg/kg B. vulgaris leaf extract (S+B 50), scopolamine+100 mg/kg B. vulgaris leaf extract (S+B 100) and scopolamine+200 mg/kg B. vulgaris leaf extract (S+B 200). Morris water maze task was used to assess spatial memory. Serum antioxidant capacity and malondialdehyde (MDA) level were also measured.<br /> Results: Group S spent significantly less time in the target quadrant compared to the control group, and the administration of B. vulgaris leaf extract (100 and 200 mg/kg) significantly increased this time (p<0.05). Scopolamine decreased serum antioxidant capacity and increased serum MDA level yet insignificantly. B. vulgaris extract (200 mg/kg) significantly increased the antioxidant capacity and decreased serum MDA level in scopolamine-treated rats (p<0.05).<br /> Conclusion: Our results suggested that B. vulgaris leaf extract could ameliorate the memory impairments and exhibited protective effects against scopolamine-induced oxidation. Further investigation is needed to isolate specific antioxidant compounds from B. vulgaris leaf extract with protective effect against brain and memory impairments.

Objective: Ferula assa-foetida, a native species in Iran, is used for treatment of several diseases particularly for neurological disorders in Iranian Traditional Medicine. The aim of this study is to investigate the effect of methanolic roots, fruits, and aerial parts extracts of Ferula assa-foetida on withdrawal syndrome in morphine-dependent mice.<br /> Materials and Methods: Aerial parts, roots, and fruits of the plant were separately extracted with 80% MeOH. For induction of dependence, morphine (50, 50 and 75 mg/kg) was injected subcutaneously three times daily (10 am, 1 pm and 4 pm) for three days and a last dose of morphine (50 mg/kg) was administrated on the fourth day. Withdrawal syndrome was induced by injection of naloxone (5 mg/kg, intraperitoneal) 2 hr after the final dose of morphine. Different doses of the extracts were administered i.p. 60 minutes before naloxone injection and withdrawal sign was recorded 2 minutes after naloxone injection for a period of 60 minutes. <br /> Results: Pre-treatment of animals with different doses (2.5, 5, 10, 20 mg/kg) of methanolic extract of the aerial parts of F. assa-foetida caused a significant decrease in naloxone-induced behavior. Intraperitoneal administration of different doses (10, 15, 20, 25 mg/kg) of methanolic extract of the fruit significantly reduced the naloxone-induced withdrawal behavior (p<0.001). <br /> Conclusion: It might be concluded that the extracts of Ferula assa-foetida affect morphine withdrawal syndrome possibly via interference with the neurotransmitters in nervous system.

Objective: Interferon-α (IFN) therapy can cause depressive symptom which may lead to drug discontinuation. By interfering with tryptophan pathway, the available level of tryptophan required for serotonin synthesis decreases which could be related to depression. The aim of this study was to evaluate whether soybean diet could improve IFN-induced depression.<br /> Materials and Methods: Male mice weighing 28±3 g were used in the forced swimming test (FST) as an animal model of depression; also, locomotor activity was recorded. IFN 16×10<sup>5 </sup>IU/kg was injected subcutaneously for 6 days. Animals were fed with regular diet or soybean diet at 3 concentrations throughout the experiment. Fluoxetine was the reference drug. To check whether the tryptophan content in the soy bean diet was effective, a group of animals was injected with a single dose of tryptophan on the test day.<br /> Results: IFN-α increased the immobility time in the FST (192 sec ± 5.4), that denotes depression in mice. Soybean diets caused less immobility that was more profound with 50% soybean (26.4 sec ± 6). This diet overcame the depression caused by IFN in the FST (54 sec±18). This result was parallel with that of tryptophan injected to animals (38 sec±17). All the animals showed normal locomotor activity.<br /> Conclusion: For the first time, we showed that soybean diet could counteract with depression caused by IFN-α. Since tryptophan therapy had similar effects, possibly the tryptophan content of soybean had induced the serotonin synthesis. Thus, not only less harmful kynurenine was produced but also more serotonin was available in the brain to overcome depression. However, this interpretation needs further evaluations.

Objective: Diazinon causes oxidative stress and dysfunction of the liver. This study was undertaken to evaluate the effects of the hydroalcoholic extract of Terminalia chebula, on some biochemical and histopathological parameters of liver tissue in diazinon-administered rats.<br /> Materials and Methods: Wistar rats were orally administered with 25 mg/kg body weight diazinon. Vehicle (distilled water) and silymarin (50 mg/kg body weight) were used as the negative and positive control groups, respectively. Diazinon-administered groups were treated with T.chebula (Terminalia chebula) fruit extract (200, 400, and 800 mg/kg). After 15 days of treatment, the blood specimens and liver samples were examined.<br /> Results: In diazinon-treated group, the levels of serum urea, high density lipoprotein (HDL), and liver superoxide dismutase (SOD), catalase (CAT), and vitamin C significantly decreased (p<0.05) compared to control. Also, in this group, serum triglyceride (TG), total cholesterol (TC), very low density lipoprotein cholesterol (VLDL), protein carbonyl (PC), malondialdehyde, tumor necrosis factor-α (TNF-α), and TNF-α gene expression significantly increased (p<0.05) as compared to the control (vehicle-treated rats). Treatment with T. chebula resulted in a significant increase (p<0.05) in CAT, SOD, vitamin C, HDL and a significant decrease (p<0.05) in the level of urea, MDA, PC, TG, TC, VLDL, TNF-α protein, and the gene expression of TNF-α compared with test without treatment group. Histopathological evidence demonstrated that treatment with T. chebula extract could decrease liver lymphocyte infiltration.<br /> Conclusion: The present study suggests that T. chebula fruit extract has protective effects against diazinon-induced oxidative stress.

<strong>Objective:</strong> Pili (<em>Canarium ovatum, </em>Engl<em>.</em>) pomace is an underutilized agricultural waste that possesses great potential to be regarded as a functional food ingredient. The aim of this study was to measure the polyphenol content and antioxidant activity of pili pomace drink and determine the influence of heating on these parameters. Moreover, it sought to assess the acute effects of thermally processed pili pomace drink on plasma antioxidant and polyphenol status in humans.<br /> <strong>Material and Methods:</strong> Ten healthy adults received a single dose (130 ml) of pili pomace drink following an overnight fasting, and blood was collected at 0, 30, 60, 120 and 240 min after ingestion of pili pomace. Plasma total polyphenol content was measured using Folin-Ciocalteu method, while total antioxidant capacity (TAC) was determined using ferric reducing antioxidant power (FRAP) assay in uricase-treated and untreated plasma samples.<br /> <strong>Results:</strong> Significant changes in plasma antioxidant and polyphenol levels were observed, reaching maximum levels at 120 and between 30 – 60 min, respectively (p<0.05). Both plasma polyphenols and TAC remained significantly above baseline values throughout the entire test period (p<0.05).<br /> <strong>Conclusion:</strong> Results raised the possibility that an acute consumption of this phenolic-rich pili pomace drink may enhance plasma antioxidant and polyphenol status in humans. Future studies on other unidentified metabolites from pili pomace that may have enhanced the antioxidant activity of plasma should be done.
