Effects of Polygala fallax Hemsl Water Extract on a Mouse Model of Gastric Motility Disorders

[Objectives]To explore the effects of Polygona fallax Hemsl water extract on gastrointestinal motility in normal mice and gastric motility disorder model mice and approximate mechanism.[Methods]Using normal mice and mice with gastric motility disorders(modeled with atropine),the effects of different mass concentration groups of P.fallax Hemsl water extract(0.125,0.250,0.500 g/mL)and domperidone groups on gastric residual rate,small intestine propulsion rate,serum motilin(MLT),vasoactive intestinal peptide(VIP),and tissue morphology were studied.[Results]There was a highly significant difference(P<0.01)in the small intestine propulsion rate of liquid in normal mice among the different concentration groups of P.fallax Hemsl water extract compared to the blank group.The small intestine propulsion rate and gastric residue rate of semi-solid paste were statistically significant compared to the blank group(P<0.05).Among them,there was a highly significant difference between the high concentration group(67.75%±7.65%,46.5%±10.62%)and the medium concentration group(60.90%±5.87%,59.27%±7.82%)(P<0.01).There was statistical significance in normal mouse serum MLT content in the high concentration group(P<0.05).There was no effect on serum VIP levels in normal mice;no effect on the morphology of stomach and intestinal tissues of normal mice.The small intestine propulsion rate and gastric residue rate of liquid and semi-solid paste in mice with gastric motility disorders were statistically significant compared to the atropine group,with extremely significant differences(P<0.01).[Conclusions]P.fallax Hemsl water extract has a promoting effect on gastrointestinal motility.One of the specific mechanisms by which P.fallax Hemsl promotes gastrointestinal motility in normal mice may be related to the content of MLT in mouse serum.The mechanism of action in atropine induced gastric paresis mice may be related to the reactivation of M receptors,and the action mechanism of P.fallax Hemsl does not change the original histological basis.It can be inferred that P.fallax Hemsl water extract has a synergistic effect on promoting gastrointestinal motility through other mechanisms,but it is not fully understood and further in-depth research is needed.

闽楠〔Phoebe bournei(Hemsl.)Yang〕种群的天然更新

调查了福建省罗卜岩自然保护区闽楠〔Ｐｈｏｅｂｅｂｏｕｒｎｅｉ（Ｈｅｍｓｌ．）Ｙａｎｇ〕种群天然更新情况，结果表明：闽楠种群天然更新良好，种子繁殖更新是其天然更新的主要方式，种群年龄结构呈“金字塔”型，它能使闽楠种群稳定增长；也可通过萌蘖繁殖进行天然更新，但更新能力较弱，种群净生殖率Ｒｏ＜１．０，内禀增长能力ｒｍ＜０，种群数量将递减。林冠下和林窗中更新均能使闽楠种群稳定增长，由于闽楠种子以重力传播为主，集中于母树周围，且幼苗与幼树能耐一定荫蔽，故在现存亚热带闽楠群落中，林冠下是闽楠种群更新的主要场所。
