[Studies on chemical constituents from Euphorbia fischeriana Steud].

Objective: To study the chemical constituents of ethanol extract from dried roots of Euphorbia fischeriana.

Method: Compounds were separated by column chromatography with silca gel and elucidated by chemical evidence and spectral analysis.

Result: Isobauerenyl acetate, beta-amyrin acetate, 24-methylenecycloartenone,octacosyl ferulate and 2,4-dihydroxy-6-methoxy-3-methyl acetophenone were isolated and elucidated.

[Argon laser peripheral iridoplasty and laser iridectomy for plateau iris glaucoma].

Objective: To evaluate the therapeutic effects of a combined laser technique for plateau iris glaucoma.

Methods: 20 cases (37 eyes) of early plateau iris glaucoma were treated by a laser technique that included argon laser peripheral iridoplasty and argon + Nd:YAG laser iridectomy.

Results: The postoperative follow-up ranged from 8 months to 4 years and 7 months (30 eyes for more than 2 years, mean 2.

[Susceptibility study on urogenital Chlamydia trachomatis to 19 kinds of antibiotics].

We detected the minimal inhibitory concentrations (MIC) and minimal bacteriocidal concentrations (MBC) of 19 kinds of antibiotics against urogenital chlamydia trachomatis (CT) from sexually transmitted disease (STD) patients. The results were as follows: (1) The mean MICs of tetracycline, doxycycline, minocycline, erythromycin, josamycin, medimycin, lomexacin and ofloxacin were lower than 0.08 microgram/ml.

Retinitis pigmentosa associated with glaucoma--clinical analysis.

A clinical analysis of Retinitis Pigmentosa (RP) was made in 2,789 eyes of 1,400 patients seen over a 5 year period (1983-1987), 64 eyes of 32 cases (2.3%) of RP associated with glaucoma were investigated. Of these 32 cases, the angle closure glaucoma was much more than the open angle glaucoma (30/2).
