Objective To study the susceptibility of Mycoplasma hominis(Mh) to several antimicrobials and Chinese medicinal herbs. Methods The minimal inhibitory concentrations(MIC) of Mh to 11 antimicrobials and 19 herbs were detected by the method of liquid microdilution. Results The sensitivity of Mh to those antimicrobials from high to low, was as follows:lincomycin, tetracycline, minocycline, levofloxacin, ciprofloxacin, ofloxacin, rifampin, spiramycin, azithromycin, erythromycin ethyl succinate and erythromycin. Among 19 herbs,Mh was sensitive to Radix Isatidis, Radix Angelicae Dahuricae, Cortex Phellodendri, Rheam Officinale, Fructus Kochiae and Herba Houttuyniae. Conclusions The susceptibility of local isolates of Mh to common antimicrobials is found out. Six Mh sensitive Chinese medicinal herbs are screened. The study provides evidences of treating Mh infection by combination of antimicrobials with Chinese medicinal herbs.

Objective To investigate the expression of IFN-? and IL-18 in patients with progressive psoriasis and its clinical significance. Methods Twenty cases of psoriasis vulgaris, 19 cases of erythroder-mic psoriasis and 10 oases of pustular psoriasis were studied. Sandwich ELISA was used to detect the plasma level of IFN-? and IL-18, or supernatant level of IFN-? and IL-18 in PBMC culture under the stimula-tion of staphylococcal enterotoxin B (SEB). Results The plasma level of IFN-? in patients with psoriasis vulgaris, erythrodermic psoriasis and pustular psoriasis was higher than that in healthy control. The plasma level of IL-18 in progressive psoriasis vulgaris was higher than that in healthy control. The supernatant level of IFN-? and IL-18 in PBMC culture in progressive psoriasis vulgaris were higher than that in normal control, with a positive correlation between IFN-? level and IL-18 level (r = 0.55, P
