Abstract
Sea buckthorn and Japanese knotweed are known in many traditional medicine systems to be a great source of bioactive substances. This research aims to compare the bioactivity and protective effects of the phenolic extracts of leaves from sea buckthorn and roots and leaves from the Japanese knotweed on erythrocytes. The polyphenol composition of the extract was analyzed using UPLC-PDA-ESI-MS/MS. The extracts' toxicity and impact on the erythrocytes' osmotic fragility were measured spectrophotometrically. The antioxidant activity was determined based on the inhibition of oxidation of erythrocytes and their membrane induced by 2,2'-Azobis(2-methylpropionamidine) dihydrochloride (AAPH),measured spectrophotometrically and using fluorimetry. To find the possible mechanism of the extracts' action, extract-modified cells were observed under a microscope, and the potential localization of the extract's phytochemical composition was checked using fluorescent probes. The results showed that the used extracts are not toxic to erythrocytes, increase their osmotic resistance, and successfully protect them against free radicals. Extract components localize on the outer part of the membrane, where they can scavenge the free radicals from the environment. Altogether, the presented extracts can greatly protect living organisms against free radicals and can be used to support the treatment of diseases caused by excess free radicals.

Abstract
Diabetes mellitus leads to chronic complications, such as nephropathy. Diabetic complications are closely related to advanced glycation end products (AGEs). Excessive formation and accumulation of AGEs in diabetic renal diseases lead to excessive oxidative stress, resulting in chronic renal failure. The leaves of Hippophae rhamnoides L. (sea buckthorn leaves; SBL) show biological benefits, including antioxidant effects. This study aimed to evaluate the effect of SBL on kidney damage in db/db mice. The SBL extract was orally administered at 100 and 200 mg kg-1 for 12 weeks to db/db mice. Histological changes and the urine albumin/creatinine ratio were relieved, and the accumulation of AGEs in kidney glomeruli decreased following SBL treatment. Moreover, the SBL extract reduced the expression of AGEs, the receptor for AGEs, and NADPH oxidase 4, but upregulated glyoxalase 1 in the diabetic renal tissue. Urinary excretion levels and expression of 8-hydroxy-2'-deoxyguanosine as a biomarker of oxidative stress decreased after SBL treatment in the renal tissue. Furthermore, SBL attenuated oxidative stress in diabetic kidneys by reducing AGE accumulation, thereby ameliorating renal damage. Therefore, from these results, we infer that the SBL extract can act as a potential therapeutic agent for diabetic renal complications caused by AGEs.

Abstract
Purpose The aim of this study was to evaluate the effects of a proanthocyanidin-rich extract of sea buckthorn berry (SBB-PE) on the numbers of various types of adult stem cells in the blood circulation of healthy human subjects. Study design and methods A randomized, double-blind, placebo-controlled, cross-over trial was conducted in 12 healthy subjects. Blood samples were taken immediately before and at 1 and 2 hours after consuming either placebo or 500 mg SBB-PE. Whole blood was used for immunophenotyping and flow cytometry to quantify the numbers of CD45dim CD34+ CD309+ and CD45dim CD34+ CD309− stem cells, CD45− CD31+ CD309+ endothelial stem cells, and CD45− CD90+ mesenchymal stem cells. Results Consumption of SBB-PE was associated with a rapid and highly selective mobilization of CD45dim CD34+ CD309− progenitor stem cells, CD45− CD31+ CD309+ endothelial stem cells, and CD45− CD90+ lymphocytoid mesenchymal stem cells. In contrast, only minor effects were seen for CD45dim CD34+ CD309+ pluripotential stem cells. Conclusion Consumption of SBB-PE resulted in selective mobilization of stem cell types involved in regenerative and reparative functions. These data may contribute to the understanding of the traditional uses of SBB for preventive health, regenerative health, and postponing the aging process.

Abstract
CONTEXT Flavonoid-enriched extract from Hippophae rhamnoides L. (Elaeagnaceae) seed (FSH) has shown beneficial effects in anti-hypertension and lowering cholesterol level. However, evidence for its efficacy in treating obesity is limited. OBJECTIVE We sought to determine if FSH can reduce body weight and regulate lipid metabolism disorder in high fat diet (HFD)-induced obese mouse model, and to investigate potential molecular targets involved. MATERIALS AND METHODS C57BL/6 mice were fed with HFD for 8 weeks to induce obesity. The modeled mice were divided into four groups and treated with vehicle, rosiglitazone (2 mg/kg), low (100 mg/kg) and high (300 mg/kg) dose of FSH, respectively. Normal control was also used. The treatments were administered orally for 9 weeks. We measured the effect of FSH on regulating body weight, various liver and serum parameters, and molecular targets that are key to lipid metabolism. RESULTS FSH administration at 100 and 300 mg/kg significantly reduced body weight gain by 33.06 and 43.51%, respectively. Additionally, triglyceride concentration in serum and liver were decreased by 15.67 and 49.56%, individually, after FSH (300 mg/kg) treatment. Upon FSH (100 and 300 mg/kg) treatment, PPARα mRNA expression was upregulated in liver (1.24- and 1.42-fold) and in adipose tissue (1.66- and 1.72-fold). Furthermore, FSH downregulated PPARγ protein level both in liver and adipose tissue. Moreover, FSH inhibited macrophage infiltration into adipose tissues, and downregulated TNFα mRNA expression in adipose tissue (38.01-47.70%). CONCLUSION This effect was mediated via regulation of PPARγ and PPARα gene expression, and suppression of adipose tissue inflammation.

Abstract
Objective: To investigate the effect of HRE (Hippophae rhamnoides extract) on oral mucositis induced in rats with MTX. Material and Methods: Experimental animals were divided into groups as healthy (HG), HRE+MTX (HMTX), and control group, which received MTX (MTXC). HMTX group received 50 mg/kg HRE while MTXC and HG groups received equivolume distilled water with gavage once a day. After one hour of HRE and distilled water administration, HMTX and MTXC groups received a single dose of oral MTX 5 mg/ kg. This procedure was repeated for one month. Results: The levels of MDA, IL-1β, and TNF-α were found to be significantly higher in the cheek, lower lip, and tongue tissue of the animals receiving MTX, compared with HG and HMTX groups; however, these parameters were lower in the cheek and low lip tissue, and a milder damage ocurred in these tissues, compared with the tongue tissue in MTXC group. No histopathologic damage was observed in the cheek, lower lip, and tongue tissues of the rats treated with HRE. Conclusion: This findings indicate that HRE as a natural product is an important advantage compared with synthetic drugs for prophylaxis of oral mucositis developed due to MTX.

Abstract
OBJECTIVES The objective of this study is to investigate and evaluate the effect of Hippophae rhamnoides extract (HRE) on oropharyngeal mucositis induced in rats with methotrexate (MTX) through biochemical, gene expression, and histopathological examinations. METHODS Experimental animals were divided into a healthy group (HG), a HRE+MTX (HREM) group, HRE group (HREG), and a control group that received MTX (MTXG). The HREM and HREG groups of rats was administered 50 mg/kg HRE, while the MTXG and HG groups were given an equal volume distilled water with gavage. Then, the HREM and MTXG rat groups were given oral MTX at a dose of 5 mg/kg 1 hour after HRE and distilled water was administered. This procedure was repeated for 1 month. At the end of this period, all of the animals were sacrificed with a high dose of anesthesia. Then, the amounts of malondialdehyde (MDA) and total glutathione (tGSH) were determined in the removed oropharyngeal tissues. Interleukin-1β (IL-1β) and tumor necrosis factor-α (TNF-α) gene expressions were measured, and all the tissues were studied histopathologically. RESULTS The amount of MDA was significantly increased in the MTXG group compared to the HREM, HREG, and HG groups (P<0.001). MTX significantly decreased the amount of tGSH in the MTXG group compared to the HREM, HREG, and HG groups (P<0.001). In this study, there were no visible ulcers in the animal group in which the levels of MDA, IL-1β, and TNF-α were high and the level of tGSH was low. However, histopathologic examination revealed mucin pools in wide areas due to ruptured oropharynx glands, and proliferated, dilated, and congested blood vessels and dilated ductal structures in some areas. CONCLUSION HRE protected oropharyngeal oxidative damage induced by MTX. As an inexpensive and natural product, HRE has important advantages in the prevention of oropharyngeal damage induced by MTX.

Hippophae rhamnoides L. Fruits Reduce the Oxidative Stress in Human Blood Platelets and Plasma. OXIDATIVE MEDICINE AND CELLULAR LONGEVITY 2016; 2016:4692486. [PMID: 26933473 PMCID: PMC4737000 DOI: 10.1155/2016/4692486] [Citation(s) in RCA: 27] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/18/2015] [Revised: 11/23/2015] [Accepted: 11/25/2015] [Indexed: 11/17/2022]
Abstract
Effects of the phenolic fraction from Hippophae rhamnoides fruits on the production of thiobarbituric acid reactive substances (TBARS, a marker of lipid peroxidation) and the generation of superoxide anion (O2−∙) in human blood platelets (resting platelets and platelets stimulated by a strong physiological agonist, thrombin) were studied in vitro. We also examined antioxidant properties of this fraction against human plasma lipid peroxidation and protein carbonylation induced by a strong biological oxidant, hydrogen peroxide (H2O2) or H2O2/Fe (a donor of hydroxyl radicals). The tested fraction of H. rhamnoides (0.5– 50 µg/mL; the incubation time: 15 and 60 min) inhibited lipid peroxidation induced by H2O2 or H2O2/Fe. The H. rhamnoides phenolic fraction inhibited not only plasma lipid peroxidation, but also plasma protein carbonylation stimulated by H2O2 or H2O2/Fe. Moreover, the level of O2−∙ in platelets significantly decreased. In comparative experiments, the H. rhamnoides fraction was a more effective antioxidant than aronia extract or grape seed extract (at the highest tested concentration, 50 µg/mL). The obtained results suggest that H. rhamnoides fruits may be a new, promising source of natural compounds with antioxidant and antiplatelet activity beneficial not only for healthy people, but also for those with oxidative stress-associated diseases.

Abstract
AIM AND OBJECTIVE Hippophae rhamnoides is an edible, nutrient rich plant found in the northern regions of India. It belongs to the family Elaeagnaceae and is well known for its traditional pharmacological activities. The present study was aimed to investigate the antioxidant and neuroprotective activities of H. rhamnoides. METHODOLOGY The hydroalcoholic extract of H. rhamnoides was evaluated for free radical scavenging activity using DPPH, hydroxyl radical scavenging and ferric thiocyanate assays. In vitro neuroprotective activity was assessed on human neuroblastoma cell line-IMR32 against hydrogen peroxide (H2O2) induced cytotoxicity. The neuroprotective effect was determined by measuring the cell viability through tetrazolium dye MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) reducing assay and propidium iodide (PI) staining. Also the intracellular reactive oxygen species (ROS) activity was assessed using dichloro-dihydro-fluorescein diacetate (DCFDA) assay by flowcytometer. RESULTS The results of the study demonstrated that H. rhamnoides extract possesses potential free radical scavenging activity. The IC50 value for DPPH and OH radical scavenging assay was 70.92 μg/ml and 0.463 mg/ml, also the extract was also found to have considerable level of lipid peroxidation activity. The neuroprotective effect of H. rhamnoides was confirmed by its cell viability enhancing capacity against hydrogen peroxide induced cell cytotoxicity. The extract acted on IMR32 cells in a dose dependent manner as observed through PI and MTT assays. The percentage intracellular ROS activity was reduced by 60-70% in treated cells compared to H2O2 control. CONCLUSION Thus the outcome of the study suggests that H. rhamnoides acts as a neuroprotectant against oxidative stress induced neurodegeneration.

Abstract
OBJECTIVE Even though there are many drugs for the treatment of gastric ulcers, these drugs sometimes cannot succeed. Since the 1950s, antidepressant drugs have been used for several non-psychiatric indications. Many antidepressant drugs have been shown experimentally to produce antiulcer activity in various ulcer models. Moclobemide is an antidepressant drug which inhibits monoamine oxidase-A (MAO) enzyme selectively. When it is compared to the classic antidepressants drugs, moclobemide is the first choice in depression treatment because of its effectiveness and less side effects. This study aimed to investigate the antiulcer effects of moclobemide and to determine its relationship with antioxidant mechanisms in rat gastric tissue. MATERIALS AND METHODS The antiulcer activities of 10, 20, 40, 80, 150 mg/kg moclobemide and 20 mg/kg famotidine have been investigated on indomethacin-induced ulcers in rats, and the results have been compared with that of the control group. RESULTS Moclobemide decreased the indomethacin-induced ulcers significantly at all doses used. While used doses of moclobemide increased the glutathione (GSH), nitric oxide (NO) level and superoxide dismutase (SOD) activity, it decreased the malondialdehyde (MDA) level and myeloperoxidase (MPO) activity in stomach tissue when compared to the control group. CONCLUSION It is determined that an antidepressant drug, moclobemide is a potent anti-ulcer agent. Inhibition of toxic oxidant radicals and activation of antioxidant mechanisms play a role in its anti-ulcer effect mechanisms.

Abstract
BACKGROUND The present study was undertaken to evaluate the anti-ulcer and antioxidant activities of the ethanol extract of Lagenaria breviflora (EELB) whole fruit in laboratory rats. METHODS The anti-ulcer property of the ethanolic extract of the whole fruit of Lagenaria breviflora (LB) was assessed using the cold-restraint stress-induced (CRU) gastric ulcer, pyloric ligation-induced (PL) gastric ulcer, aspirin-induced (ASP) gastric ulcer and alcohol-induced (AL) gastric ulcer models. The scavenging activity of the LB extract was examined with 1, 1-diphenyl-2-picryl-hydrazyl (DPPH), Nitric oxide, Hydroxyl radical and Superoxide anion scavenging models. RESULTS EELB (50, 100, 150 and 200 mg/kg, b.w.) protected against the CRU gastric ulcer dose dependently. Similarly, 150 mg/kg b.w. of the LB extract protected against the PL gastric ulcer, ASP gastric ulcer and AL gastric ulcer and was comparable to omeprazole (10 mg/kg b.w.) or Suscralfate (500 mg/kg b.w.), respectively. The in vitro antioxidant activity of LB was demonstrated by its ability to quench free radicals generated by nitric oxide and superoxide anion with a concomitant scavenging potential against DPPH-induced radical formation. CONCLUSION Taken together, the study showed that the whole fruit extract possess potent anti-ulcer and antioxidant activities.

Abstract
In the present study, the gastroprotective mechanism of Xylocarpus granatum fruit and its active constituents gedunin and photogedunin was investigated. Chloroform fraction (Fr-CHCl(3)) of X. granatum fruit was evaluated against cold restraint (CRU), aspirin (AS), alcohol (AL) and pyloric ligation (PL) induced gastric ulcer models in rats and histamine (HA) induced duodenal ulcer model in guinea pigs. Potential anti-ulcer activity of Fr-CHCl(3) was observed against CRU (58.28%), AS (67.81%), AL (84.38%), PL (65.66%) and HA (61.93%) induced ulcer models. The standard drug omeprazole (10mg/kg, p.o.) showed 68.25% protection against CRU, 57.08% against AS and 69.42% against PL model and 70.79% against HA induced duodenal ulcer. Sucralfate, another standard drug (500 mg/kg, p.o.) showed 62.72% protection in AL induced ulcer model. Fr-CHCl(3) significantly reduced free acidity (51.42%), total acidity (30.76%) and upregulated mucin secretion by 58.37% respectively. Phytochemical investigations of Fr-CHCl(3) yielded gedunin (36%), photogedunin (2%). Further, Fr-CHCl(3) and its compounds gedunin and photogedunin significantly inhibited H(+) K(+)-ATPase activity in vitro with IC(50) of 89.37, 56.86 and 66.54 microg/ml respectively as compared to the IC(50) value of omeprazole (30.24 microg/ml) confirming their anti-secretory activity. Conclusively, Fr-CHCl(3) of Xylocarpus granatum was found to possess anti-ulcerogenic activity which might be due to its anti-secretory activity and subsequent strengthening of the defensive mechanism. This study is the first of its kind to show significant anti-secretory effect of gedunin and photogedunin. Therefore it could act as a potent therapeutic agent against peptic ulcer disease.

Abstract
Abstract
The whole extract of the fresh berries of Hippophae rhamnoides L. (RH−3), which has been reported to provide protection to whole mice, various tissues, cells and cell organelles against lethal irradiation, was further investigated for its effects on mitochondria isolated from mouse liver. Superoxide anion, reduced (GSH) and oxidized glutathione (GSSG) levels, NADH-ubiquinone oxidoreductase (complex I), NADH-cytochrome c oxidoreductase (complex I/II), succinate-cytochrome c oxidoreductase (complex II/III), mitochondrial membrane potential (MMP), lipid peroxidation (LPx) and protein oxidation (PO) were determined for RH-3-mediated radioprotective manifestation. Pre-irradiation treatment of mice with RH-3 (30 mg kg−1, i.p.; single dose; −30 min) significantly inhibited the radiation-induced increase in superoxide anions, GSSG, thiobarbituric acid reactive substances (TBARS), complex I, complex I/III activity and MMP maximally at 4 h (P < 0.05). This treatment inhibited the oxidation of proteins (P < 0.05) at all the time periods studied here. This study suggests that pre-irradiation treatment of mice with RH-3 protects the functional integrity of mitochondria from radiation-induced oxidative stress.

Abstract
The study was designed to investigate the antihypertensive effect of total flavones extracted from seed residues of Hippophae rhamnoides L. (TFH-SR) and its underlying mechanism in chronic sucrose-fed rats by evaluating its ability to regulate insulin and angiotensin || levels. Feeding of high-sucrose diet (HS: 77% of kcal from carbohydrate, 16% from protein and 6% from lipid, respectively) for 6 weeks resulted in significant rise in systolic blood pressure (SBP) by 25.60%, plasma insulin by 114.24%, triglycerides by 85.14% and activated angiotensin || contents in heart and kidney. However, TFH-SR treatment significantly suppressed the elevated hypertension, hyperinsulinemia and dyslipidemia. Furthermore, TFH-SR (especially at the dose of 150mg/kg/day) increased the circulatory blood angiotensin || level as effective as angiotensin || receptor blocker. These results indicated that TFH-SR exerted its antihypertensive effects at least in part by improving insulin sensitivity and blocking angiotensin || signal pathway. Findings of the present study suggested that TFH-SR might prove to be of potential use in the management of hyperinsulinemia in non-diabetic state with cardiovascular diseases.

Abstract
The outcome of different extraction procedures (microwave, ultrasound, Soxhlet, and maceration) on the antioxidant activity of seeds, leaves, pulp, and fruits of Hippophae rhamnoides (sea buckthorn or SBT) was investigated by two different bioassays: 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt (ABTS) and 2,2'-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging assays. The SBT extracts were found to possess strong antioxidant activity measured in terms of TEAC (2.03-182.13 and 6.97-282.75 mg/g) with ABTS and DPPH assays, respectively. In general, the antioxidant capacity of microwave-assisted extracts was found to be significantly higher than those obtained by ultrasound-assisted extraction (UAE) and maceration while being slightly higher than Soxhlet extracts. Further, microwave extracts of seeds were found to possess maximum antioxidant capacity followed by leaves, fruits, and pulp. Also, the chemical composition of extracts, studied in terms of the total phenolic content, was found to be in the range of 1.9-23.5 mg/g Gallic acid equivalent (GAE), which indicates a strong correlation between antioxidant activity and phenolic content present in the SBT. In addition, some of its bioactive phenolic constituents, such as rutin ( 1), quercetin-3- O-galactoside ( 2), quercetin ( 3), myricetin ( 4), kaempferol ( 5), and isorhamnetin ( 6), were also quantified in different extracts by reverse-phase high-performance liquid chromatography (RP-HPLC).

Abstract
AIM: To examine the anti-ulcerogenic and antioxidant effects of aqueous extracts of Foeniculum vulgare (FVE) on ethanol-induced gastric lesions in rats.
METHODS: FVE was administered by gavage at doses of 75, 150 and 300 mg/kg, and famotidine was used at the dose of 20 mg/kg. Following a 60 min period, all the rats were given 1 mL of ethanol (80%) by gavage. One hour after the administration of ethanol, all groups were sacrificed, and the gastric ulcer index was calculated; whole blood malondialdehyde (MDA) and reduced glutathione (GSH), serum nitrate, nitrite, ascorbic acid, retinol and β-carotene levels were measured in all the groups.
RESULTS: It was found that pretreatment with FVE significantly reduced ethanol-induced gastric damage. This effect of FVE was highest and statistically significant in 300 mg/kg group compared with the control (4.18 ± 2.81 vs 13.15 ± 4.08, P < 0.001). Also, pretreatment with FVE significantly reduced the MDA levels, while significantly increased GSH, nitrite, nitrate, ascorbic acid, retinol and β-carotene levels.
CONCLUSION: FVE has clearly a protective effect against ethanol-induced gastric mucosal lesion, and this effect, at least in part, depends upon the reduction in lipid peroxidation and augmentation in the antioxidant activity.

Abstract
The effects of seabuckthorn (Hippophae rhamnoides L., Elaeagnaceae), leaf aqueous extract were examined in rats for its adaptogenic activity and toxicity. Dose dependent adaptogenic study of extract was carried out at different doses administered orally, 30min prior to cold (5 degrees C)-hypoxia (428mmHg)-restraint (C-H-R) exposure. After sub-acute toxicity studies on 10 and 20 times doses of maximal effective dose administered for 14 days (single oral dose of 1g/kg and 2g/kg once daily) and maximal effective dose administered for 30 days (single oral dose of 100mg/kg once daily), biochemical and hematological parameters were studied in the serum and blood. The maximal effective adaptogenic dose of the extract was 100mg/kg body weight. No significant changes were observed in organ weight/body weight ratios, of any vital organ studied (except liver and kidney in 1g/kg and 2g/kg body weight doses, respectively), and biochemical and hematological parameters of the sub-acute drug treated animals in comparison to control rats. In acute toxicity study LD(50) of the extract was observed to be >10g/kg when given orally. These results indicate that seabuckthorn leaf aqueous extract possess potent adaptogenic activity with no toxicity even after sub-acute (30 days) maximal effective dose administration.

Abstract
The present study was planned to investigate the therapeutic efficacy of Hippophae rhamnoides L. against the toxic effects of arsenic in mice. H. rhamnoides L. is used as an herbal remedy for gastric ulcers, burns, and some skin and allergic diseases. Twenty-five Swiss albino mice were exposed to arsenic (25 ppm) in drinking water for 3 months. After 3 months different fruit extracts of H. rhamnoides L. (500 mg/kg for 10 days) were administered, the animals were sacrificed, and blood and tissues were assayed for various biochemical indicators of oxidative stress and whether arsenic was removed from tissues. Treatment with different fruit extracts of H. rhamnoides L. showed significant protection from arsenic inhibition of blood delta-aminolevulinic acid dehydratase activity and restored blood reduced glutathione levels. Other hematologic variables like white blood cell counts, hemoglobin, and hematocrit were partially protected by supplementation with a water extract of H. rhamnoides L. (HF-WRT). Significant protection was also observed in altered hepatic, renal, and brain reduced/ oxidized glutathione ratio and thiobarbituric acid-reactive substances levels. The aqueous extract of H. rhamnoides L. (HF-WRT) also provided protection against parameters indicative of liver injury such as aspartate aminotransferase, alanine aminotransferase, and alkaline phosphatase activities. There was also no effect on blood and tissue arsenic concentrations observed except some moderate depletion of blood arsenic concentrations, suggesting that the drug has no ability to chelate intracellular arsenic. It can be concluded from these results that post-treatment with an aqueous extract of H. rhamnoides L. (HF-WRT) significantly protects against arsenic-induced oxidative stress but does not chelate arsenic, suggesting it may have a beneficial role as a supplementing agent during chelation of arsenic by other means.

Abstract
Allophylus serratus is known to possess various therapeutic properties. We evaluated the anti-ulcerogenic property of crude ethanolic extract of Allophylus serratus (AS) in different ulcer models in Sprague-Dawley rats. The extract at 400 mg/kg body weight, once daily, orally has a significant effect in cold restraint (CRU, 2 h cold restraint stress), aspirin (ASA, 150 mg/kg body weight, orally), alcohol (AL, 1 ml/200 gm of absolute alcohol) and pyloric ligation (PL, 4h ligation) induced gastric ulcer models as it showed protection index of 71.28, 62.50, 90.84 and 64.29% protection, respectively whereas, standard drug omeprazole (OMZ, 10mg/kg body weight) has shown protection index of 85.70, 74.99 and 74.99 in CRU, ASA and PL model respectively. Sucralfate (SUC, 500 mg/kg body weight) as a standard drug in AL model has 93.20% protection. Furthermore, AS has significantly decreased the free acidity (72.41%), total acidity (47.97%) and peptic activity (24.59%), respectively as well as has significantly increased the mucus secretion (29.41%). Conclusively the ulcer protective effect of AS may be due to its anti-secretory along with cytoprotective mechanism.

Abstract
A novel method based on reversed-phase high-performance liquid chromatography with chemiluminescence detection has been developed for the simultaneous determination of three flavonols including quercetin, kaempferol, and isorhamnetin. The procedure was based on the chemiluminescent enhancement by flavonols of the cerium(IV)-rhodamine 6G system in sulfuric acid medium. The effects of several parameters on the HPLC resolution and CL emission were studied systematically. Good separation was achieved with isocratic elution using a mixture of methanol and aqueous 1.0% acetic acid (37:63, v/v) within 25 min. Under optimized conditions, the linear working range covers 3 orders of magnitude with relative standard deviations below 4.5% for 11 replicate injected flavonol samples, and detection limits (S/N= 3) were 1.6 x 10(-8), 3.5 x 10(-9), and 6.5 x 10(-9) g mL(-1) for quercetin, kaempferol, and isorhamnetin, respectively. The chemiluminescence reaction was compatible with the mobile phase of high-performance liquid chromatography. The proposed method has been successfully applied to the determination of three active flavonols in phytopharmaceuticals of Hippophae rhamnoides L. After a simple extraction procedure, the repeatability and recovery were satisfactory.

Abstract
The present study reports the antioxidant activity of Seabuckthorn (Hippophae rhamnoides), family Elaegnaceae, on chromium induced oxidative stress in male albino rats. Oxidative stress was induced in the rats by force-feeding of potassium dichromate equivalent to a dose of 30mg/kg body weight (BW) of chromium(VI) for 30 days. Administration of chromium decreased the body weight and increased organ to body weight ratio significantly. Chromium treatment significantly decreased reduced glutathione (GSH), and increased malondialdehyde (MDA) and creatine phosphokinase (CPK) levels; further it also enhanced glutamate oxaloacetate transferase (GOT) and glutamate pyruvate transferase (GPT) levels in the serum. Different doses of the alcoholic leaf extract of Seabuckthorn were evaluated for the protection against the chromium induced oxidative stress. The results show that the leaf extract at a concentration of 100 and 250mg/kg BW protected the animals from the chromium induced oxidative injury significantly.

Abstract
Total flavones of Hippophae Rhamnoides L (TFH) are extracted from Sea buckthorn, a Chinese herbal medicine. Sea buckthorn has antioxidant, anti-ulcerogenic and hepato-protective actions, and its berry oil is reported to suppress platelet aggregation. Though it is frequently used for patients with thrombosis, the likely mechanism(s) and effects of TFH on thrombogenesis remain unclear. Thus, we have investigated the effect in-vivo of TFH on thrombogenesis and in vitro on platelet aggregation, comparing them to those of aspirin. We measured thrombotic occlusion time in a mouse femoral artery thrombosis model by the photochemical reaction between intravenously injected rose bengal and green light irradiation. In vitro platelet aggregation in whole blood was measured by single platelet counting. Thrombotic occlusion time was 8.5 +/- 0.6 min in the control group. TFH at a dose of 300 micro g/kg, intravenously administered 15 min before the rose bengal injection, significantly prolonged it to 11.6 +/- 1.0 min (P < 0.05), a similar effect on in-vivo thrombogenesis to that of aspirin. TFH at a concentration of 3.0 micro g/ml significantly (P < 0.01) inhibited in vitro platelet aggregation induced by collagen (2 micro g/ml) in a concentration dependent manner, in contrast TFH did not affect aggregation induced by arachidonic acid (80 micro M) and ADP (0.3 micro M). The results of the present study, in which TFH prevented in-vivo thrombogenesis, probably due to inhibition of platelet aggregation, suggest a possible clinical approach for the prevention of thrombosis.

Abstract
The aim of this study was to determine the effects of Hippophae rhamnoides L. extract (HRe-1) and also vitamin E as a positive control on nicotine-induced oxidative stress in rat blood, specifically alterations in erythrocyte malondialdehyde (MDA) level, activities of some erythrocyte antioxidant enzymes, and plasma vitamin E and A levels. The groups were: nicotine (0.5 mg/kg/d, intraperitoneal, i.p.); nicotine+vitamin E (75 mg/kg/d, intragastric, i.g.); nicotine+HRe-1 (1 ml/kg/d, i.g.); and control group (receiving only vehicles). There were 8 rats per group and the supplementation period was 3 weeks. Nicotine-induced increase in erythrocyte MDA level was prevented by both HRe-1 and vitamin E. Nicotine-induced decrease in erythrocyte superoxide dismutase (SOD) activity was prevented by HRe-1, but not vitamin E. HRe-1 increased the erythrocyte glutathione peroxidase (GSH-Px) activity compared with nicotine and the vitamin E groups. Catalase activity was not affected. Vitamin E supplementation increased plasma vitamin E level. Plasma vitamin A level was higher in both vitamin E and HRe-1 supplemented groups compared with nicotine and control groups. The results suggest that HRe-1 extract can be used as a dietary supplement, especially by people who smoke, in order to prevent nicotine-induced oxidative stress.
