Background and objectives: Phellinus belongs to the family of Hymenochaetaceae. In Traditional Chinese Medicine, it has been used as an ingredient for the treatment of different types of cancer, ischemia and skin diseases for thousands of years. The present study was aimed to evaluate and compare the mushroom constituents (total phenolic and flavonoid contents) and antioxidant and cytotoxic effect against cholangiocarcinoma cells. Methods: The samples of Phellinus mushrooms including P. igniarius, P.lineteus and P.nigricans were prepared in two ways: macerated in 95% ethanol and decocted in distilled water. The antioxidant activity of the six  extracts were evaluated using the DPPH, ABTS and FRAP assays. Total phenolics and flavonoids were determined using colorimetric tests. In addition, cytotoxic activities against cholangiocarcinoma cell lines (KKU-100 & KKU213A) were assessed by the SRB assay. Results: All ethanol extracts of samples showed significantly stronger antioxidant activity compared to aqueous extracts (p <0.05), while the ethanol extracts contained higher total phenolic and flavonoid contents. Phellinus linteus showed the highest antioxidant activity and total phenolic content when compared to P. igniarius and P. nigricans. All samples showed high cytotoxicity against cholangiocarcinoma cell lines, particularly the ethanol extract of P. linteus. The cytotoxicity was correlated to the phytochemical contents and antioxidant activity of each Phellinus mushroom.  Conclusions: The cytotoxicity and antioxidant activity are in proportion to the phenolic and flavonoid contents. Therefore, the antioxidant capacity of the mushroom extracts may advocate anti-cancer effects.
背景与目的:鸡毛属属膜毛科。在中医中,几千年来,它一直被用作治疗不同类型的癌症、缺血和皮肤病的一种成分。本研究旨在评价和比较香菇成分(总酚和类黄酮含量)以及对胆管癌细胞的抗氧化和细胞毒作用。方法:采用95%乙醇浸泡和蒸馏水煎煮两种方法制备火苗、lineteus和nigricans样品。采用DPPH、ABTS和FRAP测定6种提取物的抗氧化活性。用比色法测定总酚类和总黄酮。此外,通过SRB试验评估了其对胆管癌细胞株(KKU-100和KKU213A)的细胞毒活性。结果:乙醇提取物的抗氧化活性均显著高于水提物(p <0.05),总酚和总黄酮含量均高于水提物。毛茛的抗氧化活性和总酚含量均高于马齿苋和黑穗苋。所有样品对胆管癌细胞系均表现出较高的细胞毒性,特别是对黄颡鱼的乙醇提取物。细胞毒性与各菌体的植物化学成分和抗氧化活性有关。结论:黄芪的细胞毒性和抗氧化活性与黄酮类和酚类含量成正比。因此,香菇提取物的抗氧化能力可能具有抗癌作用。

Background and Objectives: Carvacrol is a natural antioxidant possessing various biological properties. Diphenhydramine is a first-generation antihistamine prescribed for allergies and the common cold. Recently, investigations have shown that diphenhydramine might cause genotoxicity. Antioxidants significantly act in defending cells against oxidative induced genotoxicity. Here, we assessed the protective effect of carvacrol, as a potent antioxidant, on diphenhydramine induced oxidative genotoxicity on human peripheral blood lymphocytes. Methods: Peripheral lymphocytes were treated as followed groups: diphenhydramine concentrations (200, 500 and 1000 µg/mL), diphenhydramine in combination with carvacrol (5 µg/mL), cisplatin (0.05 µg/mL) and cisplatin in combination with carvacrol. We evaluated the formation of micronucleus (MN), known as genotoxicity occurrence indicator, to demonstrate the possibility of diphenhydramine-induced genotoxicity. Furthermore, the level of oxidative stress was assumed by cellular glutathione oxidation and lipid peroxidation. Results: The results showed that high concentrations of diphenhydramine could cause oxidative stress damages by elevating the lipid peroxidation and glutathione oxidation. The frequency of micronucleus increased after diphenhydramine exposure (p < 0.05). Interestingly, carvacrol significantly decreased frequency of micronucleus and lipid peroxidation in lymphocytes exposed to high concentration of diphenhydramine. Conclusion:  Our results further support the idea that carvacrol has beneficial effects in protecting cells against oxidative stress damages and diphenhydramine-induced genotoxicity.
背景与目的:香芹酚是一种具有多种生物学特性的天然抗氧化剂。苯海拉明是第一代抗组胺药,用于治疗过敏和普通感冒。最近,研究表明苯海拉明可能引起遗传毒性。抗氧化剂在保护细胞免受氧化诱导的遗传毒性中起着重要作用。在这里,我们评估了香芹酚作为一种有效的抗氧化剂,对苯海拉明诱导的人外周血淋巴细胞氧化遗传毒性的保护作用。方法:将外周血淋巴细胞分为苯海拉明浓度组(200、500、1000µg/mL)、苯海拉明联合卡瓦克罗(5µg/mL)、顺铂(0.05µg/mL)、顺铂联合卡瓦克罗组。我们评估了被称为遗传毒性发生指标的微核(MN)的形成,以证明苯海拉明引起遗传毒性的可能性。此外,细胞谷胱甘肽氧化和脂质过氧化是氧化应激水平的假设。结果:高浓度苯海拉明可通过提高脂质过氧化和谷胱甘肽氧化引起氧化应激损伤。苯海拉明暴露后微核发生率增高(p < 0.05)。有趣的是,carvacrol显著降低了暴露于高浓度苯海拉明的淋巴细胞微核和脂质过氧化的频率。结论:本研究结果进一步支持了香芹酚在保护细胞免受氧化应激损伤和苯海拉明诱导的遗传毒性方面的有益作用。

Background and objectives: Development of new medicines with fewer side effects and more efficacy is needed for treatment of depressive and anxiety disorders. The present study was designed to investigate the antidepressant and anti-anxiety effects of Stachys annua L. methanol extract in mice. Methods: The extract was prepared by maceration method and the total phenolic and flavonoid contents were determined by Folin-Ciocalteu and aluminum chloride methods, respectively. Elevated plus-maze (EPM) and open field tests (OFT) were applied to evaluate the anti-anxiety and locomotor activity of animals treated with the intraperitoneal (i.p.) extract (12.5, 25, 50, and100 mg/kg), respectively. Antidepressant activity was evaluated by forced swim test (FST) and tail suspension test (TST). Results:The total phenolic content of the extract was 54.13±0.01 mg of gallic acid equivalents per gram of dry extract and total flavonoid content was 67.89±0.005 mg of quercetin as equivalents/ g of extract. Intraperitoneal administration of the extract (50 and 100 mg/kg) significantly increased the percentage of time spent and the percentage of arm entries into the open arms of EPM and decreased locomotor activity, compared with the vehicle control group. In addition, the immobility time of animals significantly decreased in both FST and TST with doses of 25, 50, and 100 mg/kg of the extract, compared with the vehicle control group. Conclusion: The extract of Stachys annua L. might be used as an adjunct therapy in clinical studies for the treatment of depressive and anxiety disorders. However, determination of active ingredients needs further evaluation.
背景与目的:开发副作用更小、疗效更高的新药是治疗抑郁症和焦虑症的迫切需要。本研究旨在探讨石竹醇提物对小鼠的抗抑郁和抗焦虑作用。方法:采用浸渍法制备提取液,采用福林法测定总酚含量,采用氯化铝法测定总黄酮含量。采用升高迷宫试验(EPM)和开放场试验(OFT)分别评价腹腔内(i.p)提取物(12.5、25、50和100 mg/kg)对动物的抗焦虑和运动活性的影响。采用强迫游泳试验(FST)和悬尾试验(TST)评价抗抑郁活性。结果:提取物中总酚含量为54.13±0.01 mg没食子酸当量/ g,总黄酮含量为67.89±0.005 mg槲皮素当量/ g。与车辆对照组相比,腹腔注射提取物(50和100 mg/kg)显著增加了EPM花费的时间百分比和进入张开臂的百分比,并降低了运动活动。此外,与车辆对照组相比,25、50和100 mg/kg提取物剂量的FST和TST组动物的静止时间均显著缩短。结论:菟丝子提取物可作为治疗抑郁、焦虑障碍的辅助疗法应用于临床研究。然而,有效成分的测定还需要进一步的评价。

Background and objectives: Sargassum angustifolium is a brown alga in southwestern coastline of Persian Gulf. Regarding the presence of various bioactive compounds and evidence of antihypertensive effects in other species of Sargassum, we evaluated the effect of S. angustifolium ethanol extract in CdCl2-induced hypertension in Wistar rats. Methods: Alga extract was prepared by maceration method using 70% ethanol and assessed for total phenolics and salt content. CdCl2 (1.5 mg/kg/day) was administered intraperitoneally to the rats for two weeks. Treatment groups received S. angustifolium extract (20, 40 and 80 mg/kg) or nifedipine (10 mg/kg) orally and simultaneously were given CdCl2 for two weeks. Systolic blood pressure (SBP) and heart rate were measured using tail-cuff method. Total antioxidant capacity, urea, creatinine, electrolytesincluding sodium, potassium, calcium and chloride were estimated in blood samples. The weight and histopathology of kidney tissues were also evaluated. Results: The content of total phenolic as gallic acid equivalent and the salt as NaCl was 67.42 ± 9.5 mg/g and 6.9 g/100 g in dried ethanol extract, respectively. CdCl2 caused significant increase in SBP, kidney/body weight ratio, serum sodium and urea level and decrease in plasma total antioxidant capacity, and also histopathological alterations in kidney tissues. Treatment with S. angustifolium extract at the doses of 40 and 80 mg/kg significantly reversed hypertension and improved kidney weight, urea level and electrolyte changes, and enhanced antioxidant capacity and preventedhistopathological changes of kidney. Conclusion: Findings of the present study indicated antihypertensive and antioxidant effects of S. angustifolium extract against CdCl2-induced hypertension in rats.
背景与目的:马尾藻(Sargassum angustifolium)是波斯湾西南海岸的一种褐藻。考虑到马尾草中多种生物活性成分的存在以及其他马尾草中降压作用的证据,我们评估了马尾草乙醇提取物对cdcl2诱导的Wistar大鼠高血压的作用。方法:采用70%乙醇浸渍法制备海藻提取物,测定总酚和含盐量。大鼠腹腔注射CdCl2 (1.5 mg/kg/天)2周。治疗组分别口服安眠叶提取物(20、40、80 mg/kg)或硝苯地平(10 mg/kg),同时给予CdCl2,疗程2周。采用尾袖法测定收缩压(SBP)和心率。总抗氧化能力、尿素、肌酐、电解质包括钠、钾、钙和氯化物在血液样本中被估计。肾脏组织的重量和组织病理学也进行了评估。结果:乙醇提取物中总酚(没食子酸当量)和盐(NaCl)含量分别为67.42±9.5 mg/g和6.9 g/100 g。CdCl2引起大鼠收缩压、肾/体重比、血清钠和尿素水平升高,血浆总抗氧化能力降低,肾脏组织病理改变。40和80 mg/kg剂量的金针叶提取物可显著逆转高血压,改善肾脏重量、尿素水平和电解质变化,增强抗氧化能力,防止肾脏组织病理改变。结论:本研究结果表明,金针叶提取物对cdcl2诱导的高血压大鼠具有抗高血压和抗氧化作用。

Background and objectives: The species of Cymbopogon are generally used for different pharmacological effects. No histopathological study has been conducted on the plant’s toxicity so far. Thus, the acute and repeated toxicity of Cymbopogon essential oil were investigated. Methods: The essential oil from aerial parts of Cymbopogon schoenanthus was administered in mice by gavage in both acute and repeated models. The animals were then divided into control and test groups. In the acute toxicity, 2000 mg/kg C. schoenanthus essential oil was administered in mice. Death rate, toxic symptoms, body weight, and abnormal behaviors were also observed for 14 days. In the repeated toxicity, C. schoenanthus essential oil (10, 100, and 200 mg/kg) was daily administered for a 4-week period. On the 28thday, all animals were sacrificed and their blood and tissue samples were prepared. Moreover, clinical, biochemical, and histopathological changes were compared to the control group. Results: No mortality was noticed in the acute test; therefore, the oral LD50 value was determined to be greater than 2000 mg/kg in the female mice. In the repeated test, the animals were given C. schoenanthus essential oil, which consequently showed no mortality and toxic symptoms. The repeated administration of C. schoenanthus essential oil had a variation on glucose, urea, Na+, and K+ levels. Moreover, the terminal necropsies revealed low toxic effects on the liver. Conclusion: The results indicate that the oral acute toxicity of C. schoenanthus essential oil in mice was of a low order with LD50 being more than 2000 mg/kg. Additionally, slight tissue damage to liver was observed when it was administered sub-chronically at the dose of 200 mg/kg.
背景与目的:杨桃属植物具有不同的药理作用。到目前为止,还没有对这种植物的毒性进行组织病理学研究。因此,对杨桃精油的急性和反复毒性进行了研究。方法:采用小鼠灌胃的方法,采用急性和重复灌胃的方式,分别给予山杨地上部分精油。然后将动物分为对照组和试验组。在急性毒性中,对小鼠施用2000 mg/kg的C.schoenthus精油。死亡率、中毒症状、体重和异常行为也观察了14天。在重复毒性中,每天给予C.schoenthus精油(101100和200mg/kg),持续4周。第28天,处死所有动物,并制备它们的血液和组织样本。此外,将临床、生化和组织病理学变化与对照组进行比较。结果:急性试验未发现死亡;因此确定雌性小鼠的口服LD50值大于2000mg/kg。在重复测试中,给动物服用了C.schoenthus精油,因此没有显示出死亡和中毒症状。重复给药对葡萄糖、尿素、Na+和K+水平有影响。此外,终末期尸检显示对肝脏的毒性较低。结论:实验结果表明,山竹精油对小鼠的急性经口毒性较低,LD50大于2000mg/kg。此外,当以200mg/kg的剂量亚慢性给药时,观察到对肝脏的轻微组织损伤。

Background and objectives: Interferon-alpha (IFN-α) is a cytokine with various clinical applications, but it may induce depression by decreasing tryptophan level and producing neuroactive metabolites. Since Linum usitatissimum (flaxseed) is a valuable source for amino acids, α-linolenic acid (ALA), and lignans that could prevent inflammation and neurotoxicity, flaxseed effects on IFN-α induced depressant was evaluated. Methods: Flaxseed was applied either by whole ground flaxseeds in mice diet, or flaxseed oil by gavage feeding tube until effective antidepressant effects were observed. Seventy-eight male albino mice 25±3 g were used and divided in 13 groups, IFN-α 16×10 5 IU/kg was injected for 6 days. After the locomotor test, the forced swimming test (FST) was used to measure the immobility time indicating despair behavior, and the sucrose preference test measured anhedonia. Results: There were only marginal differences in the locomotor activity; however, the immobility time increased by IFN-α (154.5±11.22 s, vs control 121.3±7.14 s; p=0.031), and sucrose preference was 65% indicating depression. The administration of flaxseed 30% or flaxseed oil 25% with IFN-α significantly reduced the immobility time (92.67±11.60 s and 94.17±10.12 s, respectively, vs IFN-α normal diet, p<0.01), sucrose preference also increased that supported the antidepressant effect. Conclusion: Flaxseed could prevent IFN-α induced depressive-like behavior in mice. Although interpretation from animal to human studies needs careful attention, this study supports the use of flaxseed in the diet as reasonable strategy to prevent depression in high-risk individuals, such as patients treated with IFN-α.
背景和目的:干扰素-α(IFN-α)是一种具有多种临床应用的细胞因子,但它可能通过降低色氨酸水平和产生神经活性代谢产物来诱导抑郁症。由于亚麻籽是氨基酸、α-亚麻酸(ALA)和木脂素的宝贵来源,可以预防炎症和神经毒性,因此评估了亚麻籽对IFN-α诱导的抑制剂的影响。方法:采用整粒亚麻籽在小鼠日粮中施用亚麻籽,或采用管饲法施用亚麻籽油,直至观察到有效的抗抑郁作用。78只雄性白化小鼠,25±3g,分为13组,注射IFN-α16×105IU/kg,持续6天。运动测试后,强迫游泳测试(FST)用于测量指示绝望行为的静止时间,蔗糖偏好测试用于测量快感缺乏。结果:两组患者的运动能力差异不大;然而,IFN-α使静止时间增加(154.5±11.22s,对照组为121.3±7.14s;p=0.031),蔗糖偏好为65%,表明抑郁。与IFN-α正常饮食相比,30%的亚麻籽或25%的亚麻籽油与IFN-γ联合给药显著缩短了静止时间(分别为92.67±11.60 s和94.17±10.12 s,p<0.01),蔗糖偏好也增加,这支持了抗抑郁作用。结论:亚麻籽能抑制IFN-α诱导的小鼠抑郁样行为。尽管从动物到人类的研究需要仔细解读,但这项研究支持在饮食中使用亚麻籽作为预防高危人群抑郁的合理策略,例如接受IFN-α治疗的患者。

Background and objectives: Alzheimer's disease (AD) is characterized by progressive cognitive decline. Oxidative stress plays a central role in the pathogenesis of AD. It has been proposed that administration of antioxidants affect cognitive processes, such as learning and memory. This study investigated the protective effects of vitamin E and Ginkgo biloba extract (as antioxidants) on learning and memory, hippocampal plasticity, and apoptotic marker proteins in a rat model of AD. Methods: The hyroalcoholic extract of Gingko biloba leaves wasprepared using maceration method. Male Wistar rats were randomly divided into six groups: control, sham received intra-hippocampal injection (I.H.P) of vehicle, AD model that received intra-hippocampal injection of the beta-amyloid (Aβ), AD+ vitamin E (200 mg/kg, i.p.), AD+ G. biloba (100 mg/kg/p.o.), and AD+ vitamin E (200 mg/kg, i.p.)+ G. biloba (100 mg/kg/p.o.). At the end of the treatments, the rats were subjected to the passive avoidance learning (PAL) test. The field long wterm potentials (LTP) were recorded in the hippocampal dentate gyrus. Hippocampal expressions of Bax and Bcl-2 (as pro-apoptotic, as anti-apoptotic) proteins were measured by western blot method. Results: Treatment with G. biloba and vitamin E improved the Aβ-induced memory impairment in the PAL task. Vitamin E and/or G. biloba extract enhanced the population spike amplitude evoked potentials of the LTP components, vitamin E and/or G. biloba extract increased Bcl-2 expression and decreased Bax expression in the hippocampus. Conclusion: Ginkgo biloba and vitamin E could suppress the expression of apoptosis markers and improved hippocampal LTP impairment and the memory deficit induced by Aβ.
背景与目的:阿尔茨海默病(AD)以进行性认知能力下降为特征。氧化应激在AD的发病机制中起核心作用。有人提出,抗氧化剂的管理影响认知过程,如学习和记忆。本研究探讨了维生素E和银杏叶提取物(作为抗氧化剂)对阿尔茨海默病大鼠学习记忆、海马可塑性和凋亡标记蛋白的保护作用。方法:采用浸渍法制备银杏叶水醇提取物。将雄性Wistar大鼠随机分为6组:对照组、假体海马内注射(ihp)、AD模型海马内注射β -淀粉样蛋白(Aβ)、AD+维生素E (200 mg/kg, i.p.)、AD+ G. biloba (100 mg/kg/p.o.)、AD+维生素E (200 mg/kg, i.p.)+ G. biloba (100 mg/kg/p.o.)。治疗结束后进行被动回避学习(PAL)测试。记录海马齿状回长时程电位。western blot法检测海马Bax和Bcl-2(促凋亡和抗凋亡)蛋白的表达。结果:银杏叶和维生素E治疗可改善a β诱导的PAL任务记忆障碍。维生素E和/或双叶提取物增强了LTP成分的群体峰幅诱发电位,维生素E和/或双叶提取物增加了海马中Bcl-2的表达,降低了Bax的表达。结论:银杏叶和维生素E可抑制凋亡标志物的表达,改善Aβ诱导的海马LTP损伤和记忆缺陷。

Background and objectives: Cisplatin-induced nephrotoxicity accompanies increased oxidative stress, leading eventually to kidney dysfunction. On the other hand, Pistacia vera nuts (pistachio) display multiple pharmacological effects such as antioxidant property. The present study investigated the effects of pistachio hydroalcoholic extract on nephrotoxicity induced by cisplatin in mice. Methods: Pistachios (100 g) were powdered and macerated in 1 L of ethanol (80%) for 72 h Then, dried with rotary evaporator apparatus. Forty male mice were divided into five groups: normal, cisplatin, cisplatin+DMSO, cisplatin+ pistachio hydroalcoholic extract 10, and cisplatin+ pistachio hydroalcoholic extract 100. Nephrotoxicity was induced by intraperitoneal injection of cisplatin (20 mg/kg/day) on the first day of the experiment. Pistachio hydroalcoholic extract (10 and 100 mg/kg/p.o) was administered for four consecutive days. The body weight and kidney function indices such as serum creatinine (Cr) and blood urine nitrogen (BUN) were measured. Also, the renal tissues were assessed for levels of malondialdehyde (MDA), catalase (CAT), superoxide dismutase (SOD), and glutathione peroxidase (GPx). Results: Cisplatin reduced animals’ body weight. Also, cisplatin increased levels of Cr, BUN, and MDA, and decreased the activities of SOD, CAT, and GPx. Treatment with pistachio hydroalcoholic extract (100 mg/kg) reduced the levels of serum Cr, BUN, as well as renal MDA. Moreover, administration of 100 mg/kg pistachio hydroalcoholic extract to cisplatin-treated mice increased the body weight as well as CAT, GPx, and SOD activities. Conclusion: These results imply that pistachio hydroalcoholic extract treatment may diminish cisplatin-induced renal dysfunction through reduction of oxidative stress in the kidney tissue.
背景和目的:顺铂引起的肾毒性伴随着氧化应激的增加,最终导致肾功能障碍。另一方面,开心果具有多种药理作用,如抗氧化特性。本研究探讨了开心果水酒精提取物对小鼠顺铂肾毒性的影响。方法:将开心果(100g)磨成粉末,在1l乙醇(80%)中浸泡72h,然后用旋转蒸发器干燥。将40只雄性小鼠分为正常组、顺铂组、顺铂+DMSO组、顺铂+开心果水酒精提取物10组、顺铂+开心果水酒精提取物100组。实验第1天腹腔注射顺铂(20 mg/kg/d)引起肾毒性。开心果水酒精提取物(10和100 mg/kg/p.o)连续4天。测定大鼠体重、血清肌酐(Cr)、血尿氮(BUN)等肾功能指标。同时,评估肾脏组织中丙二醛(MDA)、过氧化氢酶(CAT)、超氧化物歧化酶(SOD)和谷胱甘肽过氧化物酶(GPx)的水平。结果:顺铂可降低动物体重。顺铂增加Cr、BUN和MDA水平,降低SOD、CAT和GPx活性。开心果水酒精提取物(100 mg/kg)降低了血清Cr、BUN和肾脏MDA的水平。此外,顺铂治疗小鼠给予100 mg/kg开心果水酒精提取物可增加体重以及CAT、GPx和SOD活性。结论:开心果水酒精提取物可能通过降低肾组织氧化应激来减轻顺铂所致的肾功能障碍。

Background and objectives: Ulcerative colitis (UC) is a chronic inflammatory bowel disease. Herbal medicines such as Persicaria bistorta, Pistacia lentiscus, Punica granatum, and Myrtus communis manifesting a variety of pharmacological properties and effects, have been widely implicated in the treatment of UC. We report a case of UC in a 42-year-old male patient. Methods: The patient presented frequent passage of bloody stool, severe cramping, and abdominal pain. This was accompanied by fatigue, excessive mucus, and pus in the stool. He had a 12 years prehistoric diagnosis of ulcerative colitis and received conventional therapy, which yielded no improvement in the symptoms. His regimen was then switched to the Persian traditional treatment employing the “Sahj” formula (including Persicaria bistorta, Pistacia lentiscus, Boswellia frereana, Punica granatum, and Myrtus communis) for 4 months. Results: After 18 days of traditional therapy with “Sahj” tablet, there was a significant improvement in his UC symptoms as evidenced in the increased frequency of his bowel movements (twice daily), absence of bloating, cramping, or abdominal pain and a normal bloodless stool. A colonoscopy report and digital rectal examination 4 months post-treatment, revealed a normal perianal area, cecum, and terminal ileum.Conclusion: The results suggest that the Persian traditional “Sahj” medicine possesses pharmacological properties that render it effective in the treatment of UC and mucosal diseases. However, further clinical trials are needed to evaluate and confirm the efficacy and safety of “Sahj” therapy.
背景与目的:溃疡性结肠炎是一种慢性炎症性肠病。具有多种药理特性和作用的中草药,如Persicaria bistorta、Pistacia lenscus、石榴和杨梅,已被广泛用于UC的治疗。我们报告一例42岁男性UC患者。方法:患者表现为频繁的便血、严重的痉挛和腹痛。伴随着疲劳、粘液过多和粪便中的脓液。他在12年前被诊断为溃疡性结肠炎,并接受了常规治疗,但症状没有改善。随后,他的治疗方案改为波斯传统疗法,采用“Sahj”配方(包括Persicaria bistorta、Pistacia lenticus、Boswellia frereana、Punica granatum和Myrtus commus)治疗4个月。结果:使用“Sahj”片进行传统治疗18天后,他的UC症状有了显著改善,排便频率增加(每天两次),没有腹胀、痉挛或腹痛,大便正常无血。结肠镜检查报告和治疗后4个月的直肠指检显示肛周、盲肠和末端回肠正常。结论:研究结果表明,波斯传统的“Sahj”药物具有药理特性,可有效治疗UC和粘膜疾病。然而,还需要进一步的临床试验来评估和确认“Sahj”疗法的疗效和安全性。

Background and objectives: Umbelliprenin, a prenylated coumarin from different species of Ferula, has demonstrated anti-cancer effects in various types of cancer cells, but the potential molecular mechanisms for the anti-angiogenic activity of umbelliprenin in breast cancer cells have not yet been studied.  In this study, we investigated the possible molecular pathways involved in the anti-angiogenic effect of umbelliprenin in EGF and CoCl2 stimulated SKBR-3 breast cancer cells. Methods: Effects of umbelliprenin on the changes in EGFR signaling genes (EGFR, PI3K, AKT, mTOR, S6K, 4EBP1, ERK1/2, HIF-1α, HIF-1β, VEGF, VEGFR) and proteins (VEGF/HIF-1α) expression were assayed in SKBR-3 via Quantitative PCR and Western blotting assays. Results: Umbelliprenin dramatically decreased the living cells in a concentration related manner (IC50=103.9 µM) and non- toxic doses of umbelliprenin IC5 and IC10 (10 and 20 µM, respectively) were used for evaluating in vitro anti-angiogenic effects. Umbelliprenin significantly reduced pro-angiogenic AKT, ERK1, ERK2, mTOR, S6K, HIF-1α, HIF-1b, VEGF and VEGFR mRNAs in EGF-treated, and  AKT, ERK2, S6K, HIF-1α, HIF-1b, VEGF and VEGFR mRNAs in CoCl2-treated cells. Umbelliprenin significantly increased anti-angiogenic 4EBP1 mRNA in EGF / CoCl2-treated cells. It significantly decreased the levels of HIF-1α and VEGF proteins, in CoCl2-treated cells. Conclusion: Our findings showed that umbelliprenin exhibits anti-angiogenic effects by decreasing the expression of AKT/mTOR/MAPK angiogenesis pathways in EGF or CoCl2 treated SKBR-3 breast cancer cells.
背景与目的:伞形黄嘌呤(umbellliprenin)是一种从阿魏属植物中提取的烯丙基香豆素,已被证实对多种类型的癌细胞具有抗癌作用,但其抗乳腺癌细胞血管生成活性的潜在分子机制尚未被研究。在这项研究中,我们研究了伞丙烯素在EGF和CoCl2刺激的SKBR-3乳腺癌细胞中抗血管生成作用的可能分子途径。方法:采用定量PCR和Western blotting方法检测黄草烯素对SKBR-3中EGFR信号基因(EGFR、PI3K、AKT、mTOR、S6K、4EBP1、ERK1/2、HIF-1α、HIF-1β、VEGF、VEGFR)和蛋白(VEGF/HIF-1α)表达的影响。结果:大黄草烯苷显著降低活细胞,且呈浓度相关(IC50=103.9µM),以无毒剂量大黄草烯苷IC5和IC10(分别为10和20µM)评价其体外抗血管生成作用。大伞草素显著降低egf处理细胞中促血管生成的AKT、ERK1、ERK2、mTOR、S6K、HIF-1α、HIF-1b、VEGF和VEGFR mrna,以及cocl2处理细胞中AKT、ERK2、S6K、HIF-1α、HIF-1b、VEGF和VEGFR mrna。在EGF / cocl2处理的细胞中,伞形prenin显著增加抗血管生成4EBP1 mRNA的表达。在cocl2处理的细胞中,显著降低HIF-1α和VEGF蛋白的水平。结论:我们的研究结果表明,伞丙烯素通过降低EGF或CoCl2处理的SKBR-3乳腺癌细胞中AKT/mTOR/MAPK血管生成通路的表达而具有抗血管生成作用。

Conclusion: Our findings showed that umbelliprenin exhibits anti-angiogenic effects by decreasing the expression of AKT/mTOR/MAPK angiogenesis pathways in EGF or CoCl2 treated SKBR-3 breast cancer cells.","PeriodicalId":21088,"journal":{"name":"Research Journal of Pharmacognosy","volume":null,"pages":null},"PeriodicalIF":1.0,"publicationDate":"2020-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43040439","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
