This paper summarizes the resources of anticarcinogenic medical fungi, and the information of distribution, eco-environment. It outlines the present statuts of the exploitation and utilization of some species of common anticarcinogenic medical fungi such as Ganoderma lucidum, Coriolus versicolor, Polyporus frondosus etc. The anticarcinogenic mechanism of medical fungi is discussed. Suggestions on how to development and utilize rationally these resources are offered as well.
Studies on microcopic structure and TLC in Sarcandra glabra (Tunb.) Nakai are reported. Not only does it counteract weaknesses of former research, but it clarifies some matters well. The method to ideutify accurately this drug is provided.
The Folium Mori and the leaves of its allied species Morus australis Poir., M. mongolica Schneid. from Shandong were identified. The result shows that they are identified easily and accurately according to epidermis, trichomes and blade.
The data matrix of macro and trace elements from 45 samples of traditional Chinese medicine Xixin were treated with principal component analysis and cluster analysis in order to establish why and how Xixin samples from different species can be recognized. According to the results of hierarchical clustering, three species of Xixin (Asarum heterotropoides Fr. var. mandshuricum (Maim.) Kitag., Asarum sieboldii Miq. var. seoulense Nakai and Asarum sieboldii Miq.) were classified and recognized accurately.
Objections about the conclusions that six plants of eleven medicinal herbs given by the Materia Medica Textual Research on the Original Plants of the Medicinal Herbs in Ardisia were raised in this paper. It is considered that the eleven herbs recorded in ancient Chinese materia medica books are at least belonging to fourteen species in Ardisia and one species in Solamum.
In Yi Kezhao Alliance, the content of ephedrine and pseudoephedrine in Ephedra sinica is in a ratio of four to six. The total content of ephedine and pseudoephedrine form cultivated Ephedra sinica is higher than that of wild one, and in direct ratio with the years of plant. For the content enhance of total alkaloids, decreasing irrigation and applying middlingly fertilizer is more effective measure.
The observation of powder were carried out on fruits of 10 kinds of plants belonging to Genus Actinidia. The results pointed out obvious difference among the above species, which could be considered as one of the important evidence for identification.

Toxic studies on Fructus Psoraleae (FP) and its processed products are carried on. LD50 is 37.7 +/- 0.54 g crude drug/kg in oral administration of raw FP in comparison with 43.25 +/- 6.1/kg in that of Salt-bake one in mice. When 5.0 g/kg is given by oral for 14 days, the wet weight of testicles, preputial galnds, prostate and semianl vesicle is decreased in raw FP and its stir-bake tested groups. The wet weight of preputial glends, prostate, seminal vesicle in Lei Gong's Procession group, or prostate, and seminal vesicle in salt-steam group is also decreased to a certain extent. But no significant change on the weight of those sex organs is found in liquor-bake or salt-bake procession group, The glomerulal cell hyperplasia and cloudy swelling of renal tubules are induced by administration of raw FP in pathological examination.
