[Study on microscopic observation and TLC identification of Dai medicine "Guomaguo" (Spondias pinnata)].

OBJECTIVE: To study identification methods of Dai medicine" Guomaguo", the fruit of Spondias pinnata. METHODS: Characteristic, microscopic observation and TLC idertification were used to authenticate this crude drug. RESULTS: The characters of the cross section, powder and TLC of the drug were reported, and the relevant drawings of the tissue, powder and TLC of this ethnomedicine were drawn. CONCLUSION: These results can supply evidences for the identification of the ethnomedicine in its exploitation and utilization.

[Congenital ectropion uvea and secondary glaucoma].

OBJECTIVE: To investigate the clinical features of congenital ectropion uvea (CEU) and the relationship between CEU and secondary glaucoma. METHODS: This is a retrospective case series. Clinical features and treatments of 11 patients with CEU were summarized. Combined with the literatures review of CEU, the pathogenesis and therapeutic results of secondary glaucoma were analyzed. RESULTS: Among these 11 patients, there were 10 patients with secondary glaucoma and one patient with ocular hypertension. There were 4 patients complicated with congenital ptosis, 2 patients with ocular proptosis, 1 patient with congenital cataract, 1 patient with lens subluxation, 3 patients with ankylodactylia and 1 patient with Rieger's syndrome. The intraocular pressure of 9 patients was controlled after the trabeculectomy. CONCLUSIONS: CEU is a rare, nonprogressive anomaly accompanied other ocular abnormalities and various systemic disorders. The pathogenesis of secondary glaucoma is related to iridotrabecular dysgenesis. It is essential to detect and to treat the secondary glaucoma as early as possible.

[Study on pharmacognostic identifcation of Cassia siamea].

OBJECTIVE: To establish methods for identification of Dai medicine, the heartwoods and leaves of Cassia siamea. METHODS: Macroscopic, microscopic observation and TLC technique were used to anthenticate this crude drug, and the identification characteristics were studied. RESULTS: Macroscopic and microscopic identification methods and TLC characters of the ethnomedicine were re-ported, and the simple and detailed drawings of the transections of the heartwoods and leaves, as well as microscopic drawings of their powders were drawn in this paper. CONCLUSION: The results can serve as evidence for identification of the ethnomedicine in the utilization.

[Pharmacognostic identification on Dai medicine" guo sha" (Broussonetia papyrifera)].

The present paper reports descriptions and microscopical studies on Dai medicine" Guo sha" (Broussonetia papyrifera) , which is also the ethnomedicines of some minority nationalities in China. The diagram and the detailed drawing of the transection of the root, as well as microscopic drawing of its powder, were drawn in the studies. It was found that there are distinct microscopic characters of the transection and the powder which can serve as evidence for identification of the ethnomedicine.

[Study on microscopic identification of Dai medicine "ge ga" (Zanthoylum armatum)].

The root, bark, leaf and fruit of Zanthoylum armatum are used as traditional crude drugs by Dai and some other minority nationalities in China, and the Dai drug name is "ge ga". This paper reported microscopic, physical and chemical characters of the bark and leaf The abbreviated and detailed diagrams of the transections of the bark and leaf, and the powder diagram of the bark were drawn in the study. The result showed that there were distinct microscopic characters of the transection and the powder, and these characters could be used as evidence for identification of the ethnomedicine in the exploitation and utilization.

[RAPD Identification of Three Types of Three-lines Hybrid Rice with Defferent Male Sterile Cytoplasms and Their Parent Lines.].

The RAPD analysis was conducted on genome DNA from 21 sets of rice, including 6 three-line hybrid rice combinations, separately derived from three different kinds of cytoplasmic male sterile (CMS) lines and their related parents. Out of 264 random primers screened first, 25 primers displayed well in polymorphisms. It was shown that only 7 bands amplified respectively from 7 primers were enough to discriminate the different types of CMS, the hybrid combinations and their parents.
