Purpose To explore the feasibility of treating toothache with the acupoints in Liver Meridian. Method According to syndrome differentiation, toothache was divided into pathogenic wind-fire type and deficiency-fire type. Twenty patients were treated by needling Tai-chong (LR 3) o! the affected side. Reducing manipulation was performed for toothache due to pathogenic windfire while early-reducing-late-tonifying was performed for toothache due to deficiency-fire type. Results The pain disappearance occurred in 14 cases, improved in 5 cases and no effect in one case. Conclusion Needling Tai-chong( LR 3) was effective for toothache.

OBJECTIVETo find out the relationship between the opacity in lens and the contents of 2,6-dinitro-4-amino-toluene(DNAT) in the urine of exposed workers.

METHODSTesting the exposed worker's lens and measuring the contents of DNAT in the urine after work.

RESULTSWhen the opacity of the lens occurred, the contents of DNAT in the urine(2.38 mg/L) of workers exposed to TNT were significantly higher than those without opacity in lens(1.44 mg/L) (P < 0.05).

CONCLUSIONThe severity of opacity of lens increased with the contents of DNAT raised in the urine. The threshold value suggested by ILO is not applicable to Chinese occupational population, which recommends the contents of DNAT(30 mg/L) in the urine for the workers exposed to TNT as biological occupational exposed limits.
