Protective Effect of Polygala fallax Hemsl. On Experimental Gastric Mucosal Lesion
Abstract: ObjectiveTo observe the mucosal protective
effect of Polygala fallax Hemsl.in experimental model of gastric lesion in mice.MethodsThe four models of gastric mucosal lesion in mice induced by ethanol absolute, aspirin, reserpine injection and water immersion stress were established.The areas of gastric mucosal lesion in mice were measured.ResultsIt was found that Polygala fallax Hemsl. obviously inhibited lesion degrees of gastric mucosa of the four models.ConclusionPolygala fallax Hemsl. possesses protective effect on experimental gastric mucosal lesion in
Key words: Polygala fallax Hemsl; Gastric mucosal lesion; Mice
Polygala fallax Polygala fallax Hemsl. (PFH)  also known as the fake yellow Polygalaceae, the main produced in Hunan, Guangxi, Jiangxi, Guangdong and Yunnan and other
places, medicinal its wholly-grass. Sweet, slightly bitter
flavor, sexual level. With replenishing, strong, dampness, Sanyu efficacy, attending virtual weak swelling, acute and chronic hepatitis, waist, leg pain, bruises, . Some people
have been reported fallax extracts on immune organs . Are reported fallax extracts on experimental gastric mucosal injury in rats.
1.1 Animals Kunming mice, male and female in half, body weight (22.0 ? 1.5) g, from Jiangxi Medical College
Laboratory Animal Center, Animal qualified证号: 2006
075. Randomized. In the laboratory before the experiment to adapt to 1 week after the experiment.
1.2 Drugs and reagents to take dry water fallax (purchased from pharmaceutical companies Ganzhou) 200 g, with
double distilled water than surface 2 cm, boiled 2 times. 30 min / times, combined filtrate, concentrated to 400 ml. Plus three times the amount of 95% ethanol, Fang Bingxiang put it aside overnight, the next day vacuum filtration, and recycling
the filtrate of ethanol, to continue to concentrate the filtrate was non-alcoholic flavored extract. Extract with double distilled water to 200 ml, so that liquid is the equivalent of crude drug 1 g / ml. With 0.5% NaOH to adjust pH 7.0. Home refrigerator spare.

2.1 The ethanol-induced gastric mucosal injury model in mice prepared by taking 40 Kunming mice were randomly divided
into 5 groups: normal saline control group, model group,
cimetidine group fallax extracts of low-dose group, Polygala
fallax high-dose group. Each gavage 1 / d, a continuous 7 d. Gavage 7 days after fasting 24 h, can not help but water. On
the 8th day after the last dose 1 h, in addition to normal saline control group, mice in each group were fed ethanol (0.1 ml / only), 1h after cervical dislocation of mice were sacrificed.
2.2 of aspirin-induced gastric mucosal injury model in
mice Preparation of animal grouping and drug delivery methods are the same before. At 1 h after the last dose, in addition to normal saline control group, each group of mice fed aspirin 0.25 g / kg, 4 h after the mice were sacrificed.
2.3 Flooding stress-induced gastric mucosal injury model
in mice Preparation of animal grouping and drug delivery methods are the same before. 1h after the last administration, in addition to normal saline control group, each group of mice under ether anesthesia at the iron bars on the mice bondage
placed (23 ? 0.5) ? in water bath, the liquid level to keep the sword in the sternum sudden level. 7 h after the mice were sacrificed.
2.4 reserpine-induced gastric mucosal injury model in
mice Preparation of animal grouping and drug delivery methods
are the same before. At 1 h after the last dose, in addition to normal saline control group, the subcutaneous injection of 10 mg / kg reserpine, 6 h after the mice were sacrificed. Reposted elsewhere in the paper for free download http://
The experimental animals were killed after the Cesarean section, separating the stomach, gastric cardia and pyloric ligation to the stomach cavity injection of 10% formaldehyde solution, 2 ml, will be immersed in the stomach in the same
concentration of formaldehyde solution, 20 min after the cut along the greater curvature of stomach appetizer, Water rushed gastric residue, expand the stomach and placed under a microscope, observe the degree of gastric mucosal damage, and calculated on the grid area of gastric mucosal damage to each area of gastric mucosal damage in mice (mm2) of the sum of its damage index . Ulcer index, calculated as follows: ulcer points, or 1 mm below surface, namely, 1 minute; 1 ~ 2 mm were, namely, two points; 2 ~ 3 mm were, namely, 3 points; 3 ~
4 mm were, namely, four points; more than 4 mm were, namely,
five points shall be added to the scoring of the animals of the ulcer index, and calculate the inhibitory rate of ulcers.
3.1 fallax extract on ethanol induced gastric mucosal injury in rats results show that different doses of extract of Polygala fallax index of gastric mucosal damage in mice compared with the model group were significant differences. The results in Table 1. Table 1 fallax extracts on ethanol
induced gastric mucosal injury in rats (omitted)
3.2 fallax extracts on aspirin-induced gastric mucosal
injury in mice showed that different doses of extract of Polygala fallax gavage of aspirin caused gastric mucosal injury were significantly protective effect of . The results in Table 2. Table 2 fallax extracts on aspirin induced gastric mucosal injury in rats (omitted)
3.3 fallax extracts on water immersion stress-induced
gastric mucosal injury in mice of different doses of Polygala
fallax extracts on water immersion stress-induced gastric
mucosal injury significantly inhibited. The results in Table 3. Table 3 fallax extracts on water immersion stress induced gastric mucosal injury in rats (omitted)
3.4 fallax extract on reserpine-induced gastric mucosal
injury in different dose groups extract of Polygala fallax on the reserpine-induced gastric mucosal injury in mice
significantly inhibited. The results in Table 4. Table 4 fallax extract on reserpine-induced gastric mucosal injury in
Current gastric ulcer formation due to a combination interpretation of the theory has not yet formed a positive cause. The pathogenesis of ulcer disease may be due to gastric acid and pepsin digestion ability and the balance between the gastric mucosal barrier function disorder. Mental or emotional, stress, drugs and diet are caused by ulcers incentives. Based on available chemical, physical stimulation as well as through a variety of stress-induced ulcers
pathological model. In this study, a variety of animal models
of gastric ulcer, from different angles of Polygala fallax extracts on gastric mucosal protective effect. The results showed that fallax extracts significantly reduced by ethanol, aspirin, flooding stress and reserpine induced gastric mucosal injury, showed significantly reduced damage index, ulcer inhibitory rate increased significantly. Tips fallax extracts on a variety of models of experimental gastric mucosal injury caused by both a protective effect, these results for clinical for the treatment of peptic ulcer provides a theoretical basis.
