[Anti-tumor mechanism of active components from extract of Actinidia rufa root].

Objective: To observe effect and mechanism of n-Butanol lysate of alcohol extracts from Actinidia rufa root (monomer of R6,R8).

Method: Tunel, Wright's stain with Giemsa's stain dyeing, and Hoechst 33258-PI double dyeing assay were used to detect the apoptosis of SGC7901 tumor cells treated with R6, R8. The SGC7901 tumor cells were randomly divided into control group and two treatment groups administered 0.

[Study on the anticancer effects of extracts from roots of Livistona chinensis in vitro].

Objective: To observe the effects of extracts from root of Livistona chinensis on the growth inhibition in seven carcinoma cell lines.

Methods: The growth inhibition was analyzed by MTT, cell colony and cell growth curve measuremen technique in the stomach carcinoma SGC7901, Lymphocytic leukemia L1210, Lymphoid neoplasm P388D1, tumor of cervix uteri Hela, hepar carcinoma hele 7404, melanoma B16 and mouse neuroblastomax rat glioma hybrid NG108-15 cells lines.

Results: The growth of all tumor cells were inhibited by ethyl acetate of alcohol extract from roots of Livistona chinensis.

[Effects of the Panax notoginseng saponins on the level of synaptophysin protein in brain in rat model with lesion of Meynert].

Objective: To observe the protective effect of Panax notoginseng saponins (PNS) on the level of synaptophysin ptotein in brain in rat model with Alzheimer's disease (AD).

Method: The AD rat models were established by intra-peritoneal injection of D-galactose combined with excitatory neurotoxin ibotenic acid injection into bilateral nbM. The activity and content of synaptophysin protein in brain were determined by immunohistochemistry analysis.
