绶草是我国濒危二级保护植物,现已列入《濒危野生动植物种国际贸易公约》。但由于种子极小,属于无胚乳类型,自然条件下种子萌发率极低。随着人们对绶草药用价值和观赏价值的认识,绶草的驯化栽培及营养繁殖等人工繁育技术是解决绶草资源保存、重新引入自然界及满足商业需求的最有效方法。本研究以张家口市宣化区常峪口村的野生绶草植株为试验材料,利用不同的栽培基质(处理1:草炭土∶蛭石=3∶1,处理2:草炭土∶园土∶蛭石∶饼肥=2∶2∶1∶1,处理3:100%根原土)进行绶草人工驯化栽培试验,测定不同栽培基质的物理性状以及不同栽培基质的绶草根际真菌分布情况,观测绶草植株移栽后的发育期进程、株高、花茎长度及花量等处理效果。结果表明,不同栽培基质的密度和容重比较,处理3>处理2>处理1,3个处理的总孔隙度分别为72.1%、65.3%和54.6%,p H值分别为5.9、6.4和7.5;并对3种栽培基质进行真菌分离,处理1分离出5种真菌,处理2分离出6种真菌,处理3的真菌种类最多,共8种;结合不同基质下绶草的株高、花茎长度和花量等生长指标分析,处理3对于植株的生长状况及发育期进程的影响最大、处理效果最佳,处理1次之,处理2效果稍差,虽然3种处理下的植株生长状况有所不同,但在人工驯化过程中,3种基质下的绶草均未出现停长或死亡现象,表明3种栽培基质均可成功用于人工驯化绶草植株。

AIM: To study the effects of He-Ne laser irradiation on experimental chronic atrophic gastritis (CAG) in ***: Sixty-three male adult Wistar rats were randomly divided into five groups including normal control group, model control group and three different dosages He-Ne laser groups. The chronic atrophic gastritis (CAG)model in rats was made by pouring medicine which was a kind of mixed liquor including 2% sodium salicylate and 30% alcohol down the throat for 8 wk to stimulate rat gastric mucosa, combining with irregular fasting and compulsive sporting as pathogenic factors; 3.36, 4.80, and 6.24J/cm2doses of He-Ne laser were used, respectively for three different treatment groups, once a day for 20 d. The pH value of diluted gastric acid was determined by acidimeter,the histopathological changes such as the inflammatory degrees in gastric mucosa, the morphology and structure of parietal cells were observed, and the thickness of mucosa was measured by micrometer under optical ***: In model control group, the secretion of gastric acid was little, pathologic morphological changes in gastric mucosa such as thinner mucous, atrophic glands, notable inflammatory infiltration were found. After 3.36 J/cm2 dose of He-Ne laser treatment for 20 d, the secretion of gastric acid was increased (P＜0.05), the thickness of gastric mucosa was significantly thicker than that in model control group (P＜0.01), the gastric mucosal inflammation cells were decreased (P＜0.05). Morphology, structure and volume of the parietal cells all recuperated or were closed to ***: 3.36J/cm2 dose of He-Ne laser has a significant effect on CAG in rats.

Total flavonoids are the main pharmaceutical components of Trollius chinensis Bunge, and orientin and vitexin are the monomer components of total flavonoids in Trollius chinensis Bunge. In this study, an aged mouse model was established through intraperitoneal injection of D-galactose for 8 weeks, followed by treatment with 40, 20, or 10 mg/kg orientin, vitexin, or a positive control （vitamin E） via intragastric administration for an additional 8 weeks. Orientin, vitexin, and vitamin E improved the general medical status of the aging mice and significantly increased their brain weights. They also produced an obvious rise in total antioxidant capacity, superoxide dismutase, catalase, and glutathione peroxidase levels in the serum, and the levels of superoxide dismutase, catalase and glutathione peroxidase, Na＋-K＋-ATP enzyme, and Ca2＋-Mg2＋-ATP enzyme in the liver, brain and kidneys. In addition, they significantly reduced malondialdehyde levels in the liver, brain and kidney and lipofuscin levels in the brain. They also significantly improved the neuronal ultrastructure. The 40 mg/kg dose of orientin and vitexin had the same antioxidant capacity as vitamin E. These experimental findings indicate that orientin and vitexin engender anti-aging effects through their antioxidant capacities.
