Ethnopharmacological relevance
Argyreia speciosa (L.f), Sweet (Family Convolvulaceae) is used traditionally in Indian System of Medicine as aphrodisiac, rejuvenating agent, intellect promoting agent, brain tonic and in the therapy of hepatomegaly, diabetes and chronic ulcer.Aim of the study
To study the gastroprotective effect of standardized butanol fraction of Argyreia speciosa leaf (ASE).Materials and methods
The butanol fraction of Argyreia speciosa leaf (ASE; 50, 100 and 200 mg/kg body weight) was administered orally, twice daily for 5 days for prevention from Aspirin (ASP)-, ethanol (EtOH)-, cold-restraint stress (CRS) - and pylorus ligation (PL)-induced ulcers. Estimation of antioxidant enzymes activity was carried out in CRS-induced ulcer model, and various gastric secretion parameters like volume of gastric juice, acid output, and pH value were estimated in PL-induced ulcer model.Result
ASE showed dose-dependent ulcer protective effect in ASP 23.64-58.76% (p < 0.01 to p < 0.001), EtOH 15.45-58.45% (p < 0.001), CRS 19.39-78.36% (p < 0.001) and PL 19.67-69.04% (p < 0.05 to p < 0.01), respectively. The percentage of protection by standard drug ranitidine was 77.77-84.32% (p < 0.01 to p < 0.001) in various gastric ulcer models. The gastric wall mucus was significantly (p < 0.001) enhanced by ASE and is regarded as the first line of defence against EtOH-induced gastric ulcers showing cytoprotective property. ASE showed a marginal decrease in volume, acid pepsin concentration and acid pepsin output. However, ASE reduced the ulcer index with significant decrease in LPO level (p < 0.001), and SOD level (p < 0.01 to p < 0.001) as compared with CRS-induced group. A gradual and significant increase in CAT values were observed at 100 and 200 mg/kg dose levels (p < 0.01 to p < 0.001).Conclusions
The results of our study revealed that Argyreia speciosa possess significant dose dependent gastroprotective activity, probably due to its free radical scavenging activity. 相似文献7.
The vasodilator effect of the ethanolic extract of leaves from Hancornia speciosa Gomes (HSE) was studied in rat aortic rings. HSE produced a concentration-dependent vasodilatation (pIC(50)=5.6+/-0.1), which was completely abolished in endothelium-denuded vessels. The endothelium-dependent vasodilatation induced by HSE was abolished by l-NAME (100 microM), a nitric oxide (NO) synthase inhibitor, but not atropine (1 microM; pIC(50)=5.6+/-0.2), a muscarinic receptor antagonist, nor indomethacin (10 microM; pIC(50)=5.4+/-0.2), a cyclooxygenase inhibitor. The concentration-response curve of HSE was significantly shifted to the left by superoxide dismutase (SOD; 300U/mL). In addition, while SOD displaced the 3-morpholino-sidnonimine (SIN-1; P<0.05) concentration-effect curve to the left, HSE (50 microg/mL) had no effect. Finally, wortmannin (0.3 microM), an inhibitor of phosphatidyl-inositol 3-kinase (PI3K), dramatically reduced the vasodilator effect of HSE. Together, these findings lead us to conclude that HSE induces a NO- and endothelium-dependent vasodilatation in rat aortic preparations, likely by a mechanism dependent on the activation of PI3K. 相似文献

Benign prostatic hyperplasia (BPH) is a urologic disease that affects most of men over the age 50. But until now there is no such perfect cure without side effects. Because of diverse adverse effects, it is desirable to develop effective and long term‐safety‐herbal medicines to inhibit the progress of BPH. In spite of garlic's large use and a wide spectrum of studies, including anti‐hyperlipidemic, cardio‐protective, and anti‐inflammatory activities, there was none to prove efficacy for BPH. In this study, we evaluated the efficacy of garlic to prove its suppressing effects on BPH. Garlic administration decreased relative prostate weight ratio, suppressed mRNA expression level of AR, DHT serum levels, and the growth of prostatic tissue in BPH‐induced rats. Moreover, garlic administration decreased the levels of inflammatory proteins, iNOS, and COX‐2 in prostatic tissue. Further investigation showed that garlic induced accumulation of death‐inducing signal complex and activation of AMPK and decreased the levels of anti‐apoptotic proteins, such as Bcl‐2, Bcl‐xL, and survivin. These results suggest that garlic may have suppressing effects on BPH and it has great potential to be developed as treatment for BPH. Copyright © 2016 John Wiley & Sons, Ltd. 相似文献

Kratom (Mitragyna speciosa Korth.) is an indigenous plant of Thailand used traditionally in folk medicine although it is claimed to cause addiction. It is used to treat diarrhea, however, there is no scientific evidence to support the use. The aim of this study is to investigate the effect of methanolic extract of kratom leaves on the rat gastrointestinal tract. Kratom extract at 50, 100, 200 and 400 mg/kg (p.o.) caused a dose dependent protection against castor oil-induced diarrhea in rats and also inhibited intestinal transit. The antidiarrheal effect was not antagonized by naloxzone. The inhibition of intestinal transit by kratom extract was significantly different from the control when treated with a single dose for 1 day. For longer-term treatments of 15 and 30 days, kratom extract did not decrease the intestinal transit time indicating that adaptation had occurred. Kratom extract at a dose level of 200 and 400 mg/kg for 30 days and morphine at 3 mg/kg (i.p.) caused a decrease in the increment of body weight that was significantly different from the control and kratom extract at lower doses (50 and 100 mg/kg). However it had no effect on the level of plasma cholecystokinin. The results suggested that methanolic kratom extract exhibited its antidiarrheal effect on rat gastrointestinal tract. The effects may occur via pathways in addition to the action on opioid receptors. High does of kratom extract decreased the increment of body weight similar to the effect of morphine. 相似文献

Ethnopharmacological relevance
The leaves of Hancornia speciosa Gomes are popularly used in Brazil to treat diabetes and hypertension. Cardiovascular diseases are the main cause of death worldwide and their incidences are increasing in Brazilian population. The present study aimed to investigate the hypotensive effect and the mechanism of action of Hancornia speciosa Gomes.Methods
A fraction of the ethanolic extract of leaves from Hancornia speciosa (SFH) was obtained and standardized by its content on rutin, bornesitol and quinic acid. Systolic blood pressure (SBP) of normotensive mice was measured by tail pletismography. SFH was given orally and SBP was monitored for 5 h. Angiotensin-converting enzyme (ACE) inhibitor activity of SFH (1 mg/kg) or captopril (10 mg/kg) was measured by colorimetric methods. Serum nitrite levels were measured by spectrophotometry.Results
SFH induced a dose-dependent hypotensive effect in normotensive mice. The serum activity of ACE and the level of angiotensin II were significantly reduced by SFH and by captopril. Administration of SFH induced a significant increase on plasmatic level of nitrites and the systemic inhibition of nitric oxide synthase by L-NAME (20 mg/kg) reduced the hypotensive effect of SFH.Conclusions
The present work demonstrated that Hancornia speciosa has a potent hypotensive effect in normotensive mice. The inhibition of ACE leading to reduction on angiotensin II and increase on NO levels might account for the hypotensive effect. These results support the use of Hancornia speciosa by traditional medicine as antihypertensive. 相似文献17.

Ginkgo biloba L. (Ginkgoaceae) originated from China, first introduced to Europe in the 18th century, it is now distributed all over the world. The leaves of Ginkgo biloba include a rich complex of active compounds responsible for various pharmacological properties. Ginkgo biloba extract improves blood circulation, protects against oxidative cell damage, blocks platelet aggregation that could be important for prevention of cardiovascular diseases. Therefore the fluid extract from Ginkgo biloba leaves was prepared and tested for it is effect on rat mitochondrial function. Our data showed that 0.5 microl/ml of GE (containing 0.57 ng/ml of rutin, 0.23 ng/ml of quercitrin, 0.105 ng/ml of hyperosid and 0.02 ng/ml of quercetin) had no effect on the State 2 respiration rate of mitochondria with all used substrates: pyruvate+malate, succinate and palmitoyl-L-carnitine. Further increase in GE concentration (2 and 4 microl/ml), increased the State 2 respiration rate with all respiratory substrates in a dose-dependent manner (by 35-116%). The State 3 respiration rate was not affected by GE. In order to identify which compounds of GE could be responsible for the observed effects, we measured the effect of pure flavonoids: rutin, quercetin, hyperosid and quercitrin on mitochondrial respiration. All flavonoids (except of hyperosid) at maximal used concentration, comparable/identical to that in GE, stimulated the State 2 respiration rate only by 8-20%, i.e. less effectively as compared to GE. Therefore, for the explanation of the GE-induced uncoupling of oxidative phosphorylation, other biologically active compounds of GE have to be taken into account in future studies. 相似文献
