 ANTI – ULCER ACTIVITY OF POLYHERBAL FORMULATION – RO12 ON EXPERIMENTALLY INDUCED ULCER IN RATS

RO12, a polyherbal formulation, is a marketed drug which has been used in various gastrointestinal problems, however, there is no such clear documentation for antiulcer activity. So, the present study was carried out to test its antiulcer activity in rats using different models. Wistar rats were grouped into four, each group with 6 animals and injected with Normal Saline (control), Ranitidine 50 mg/kg (Standard drug), RO12 aqueous extract 200mg/kg and 400mg/kg (test drug) per orally in case of pylorus ligation model. In case of ethanol induced ulcer, misoprostol 10 mcg/kg was given as standard keeping everything else same as pylorus ligation method. Acute gastric ulceration in rats was produced by oral administration of ethanol and by pylorus‐ligated technique. The results showed that in both pylorus ligation and ethanol induced ulcer models, the aqueous extract RO12 exhibited significant decrease (P<0.001) in ulcer index, ulcer score, free acidity, total acidity, pepsin content in pylorus ligation induced ulcer as well as in ethanol induced ulcer models. This study demonstrated that, RO12 polyherbal formulation possess significant antiulcer activity. The aqueous extract of RO12 possesses dose dependent antiulcer effect. Current studies confirmed the claimed antiulcer activity in selected doses (200mg/kg and 400mg/kg).

EXPERIMENTAL EVALUATION OF THE ANTI ULCER ACTIVITY OF GRAPE (VITIS VINIFERA) SEED EXTRACT IN WISTAR ALBINO RATS AGAINST HYDROCHLORIC ACID – ETHANOL INDUCED ULCER MODEL

The study of the effect on gastric lesions by GSE by employing ethanol was done by in 2005 [30]. They evaluated the gastric defense mechanism of grapefruit seed extract against ethanol and stress- induced gastric lesions in male Wistar rats by inducing gastric mucosal lesions by 100% ethanol or 3.5 hrs of water immersion stress. Their study showed a significant fall in the gastric blood flow and superoxide dismutase activity and rise in the mucosal malondialdehyde (MDA) content. Pretreatment with GSE caused a dose dependent attenuation of gastric lesions and, the dose reducing these lesions by 50% was 25 and 36 mg/kg respectively. The study showed GSE exerting a potent gastroprotective activity through an increase in endogenous prostaglandin generation, suppression of lipid peroxidation, and hyperemia. The results obtained in this study do not correlate to the study quoted above. The reasons for this can be the higher concentration (100%) of ethanol being used, and also the different parameters analyzed in their study.

Anti gastric ulcer activity of Ficus nervosa bark in wistar albino rats

Anti gastric ulcer activity of Ficus nervosa bark in wistar albino rats

The anti ulcer activity of ficus nervosa was evaluated by pylorus ligation, aspirin, alcohol induced ulcer models. These models represent some of the most common causes of gastric ulcers in human. So it has been proposed that in pyloric ligation, the digestive effect of accumulated gastric juice and interference of gastric blood circulation are responsible for induction of ulceration [19].The anti ulcer activity of ficus nervosa extracts in pylorus ligation model is evident from its significant reduction in gastric volume total acidity, free acidity, ulcer index and increase in pH of gastric juice. NSAIDs like aspirin causes gastric mucosal damage by decreasing prostaglandin levels through inhibition of PG synthesis. [20] Ethanolic extract of the plant of ficus nervosa was significantly effective in protecting gastric mucosa against aspirin induced ulcers. Ethanol induced gastric injury is associated with significant production of oxygen free radicals leading to increased lipid peroxidation ,which cause damage to cell and cell membrane[21]. The various extracts of ficus nervosa has significantly protected the gastric mucosa against ethanol challenge as shown by reduced values of lesion index as compared to control group suggesting its potent cytoprotective effect. Preliminary phytochemical studies revealed the presence of flavonoids. So the possible mechanism of antiulcer action of ficus nervosa bark may be due to its flavonoid content. In this study we observed that ficus nervosa provides significant anti ulcer activity against gastric ulcer in rats.

In another experimental model, the anti-diabetic effects of ethyl acetate, petroleum ether and chloroform fractions were investigated from the methanolic extract of seeds of Entada phaseoloides in AIDM (alloxan induced diabetic mice) by Ikram and his associates (2011). The effect of these fractions (200 mg/kg body weight i.p) was observed on FBG (fasting blood glucose) level and active fraction was further investigated for its dose dependent activity (250 mg/kg and 350 mg/kg body weight) on fasting blood glucose level and also on TC (total cholesterol), TG (triglyceride), SGOT (serum glutamate oxaloacetate transaminases) and SGPT (serum glutamate pyruvate transaminases) level in AIDM which showed significant effects. The most significant reduction of FBG level of around 72.02% was observed for Et-Ac fraction in AIDM. A significant reduction (p<0.05) in serum TC and TG level of 53.00% and 57.25% respectively was also found for Et-Ac fraction of E. Phaseoloides. The hypoglycemic and hypolipidemic activities were comparable to metformin HCl (150 mg/kg). In diabetic mice, SGOT and SGPT levels were significantly elevated that were further reduced after intra peritoneal administration of this fraction. These results indicated ethanolic fraction of E. Phaseoloides have favorable effects in bringing down the severity of diabetes together with hepatoprotectivity.

Evaluation of Anti-Ulcer Activity of Pithecellobium Dulce Seeds In Albino Wistar Strain Rats

Evaluation of Anti-Ulcer Activity of Pithecellobium Dulce Seeds In Albino Wistar Strain Rats

Peptic ulcer and gastritis have been associated with multi pathogenic factors and could be due to disturbances in natural balances between the aggressive factors (e.g. of acid, bicarbonate, pepsin) and maintenance of the mucosal integrity through the endogenous defense mechanism. Generally various non specific methods are used to restore these imbalances including regular food intake, adequate rest, and avoidance of ulcerogenic agents (e.g. tobacco, alcohol and coffee).Their aims are to attenuate and possibly block the gastric acid secretion or to enhance the mucosal defense mechanisms. The latter can be achieved through increasing mucus production, stabilizing the surface epithelial cells, or interfering with the prostaglandin synthesis. In addition there are also drugs, such as pump inhibitors, histamine (H2)-antagonists, anti cholinergics and antacids, used in the treatment of ulcer.

MEDICINAL PLANTS WITH ANTI ULCER AND HEPATOPROTECTIVE ACTIVITY: A REVIEW

MEDICINAL PLANTS WITH ANTI ULCER AND HEPATOPROTECTIVE ACTIVITY: A REVIEW

ABSTRACT: Nature gives numbers of drugs and possibly has all solutions for human diseases. Till date, nature provides a large number of clinically useful drugs. Ulcer and liver diseases are major increasing health problems. Now a day number of drugs are used for the treatment of peptic ulcer and hepatic diseases, but these drugs have various types of side effect such as incidences of relapse, and drug interactions. Drugs of plant origin gaining popularity to treat peptic ulcer and hepatotoxicity. It is difficult to search pure phytochemicals as hepatoprotective and antiulcer drugs. It is time- consuming and also very expensive. From authentic literature sources, it founded that there are no medicinal plants, which utilized for the treatment of ulcer and liver diseases. Andrographis paniculata, Eclipta alba, Picrorrhiza kurroa, Silibum marianum, Phyllanthus and Trichopus zeylanicus, etc. plants are renounced for their satisfactory activity against certain hepatotoxins. The wide range of compounds showing anti-ulcer and hepatoprotective effect, among them flavonoids is most important. Flavonoids play an important role in reducing free radicals. Various isolated compounds like apigenin, sylimarin, genistein, quercetin, kaempherol, catechins and so on show the significant result as hepatoprotective and anti-ulcer drugs. From this review article, we can conclude that no. of medicinal plants and their active chemical constituent are responsible for anti-ulcer and hepatoprotective effect. Among the all chemical constituents flavonoids also playing an important role.
