In recent years, gonorrhea has been pandemic and remains one of the most common STDs in the world, especially in developing countries. For the detection of a more effective therapeutic regimen and assessing the prevalence of Penicillinase Producing Neisseria gonorrhoeae(PPNG), we have been trying to study the patients who have visited the Venereal Disease Clinic of Choong-Ku Public Health Center in Seoul since 1980 by menas of the chromogenic cephalosporin method. In 1998, 93 strians of N. genorrhoeae were isolated, among which 60(64.5%) were PPNG. The prevalence of PPNG in Seoul, which had been decreased to 39% in 1996 after a peak of 74.3% in 1993, is increased to 64.5% in 1998.

Glucose concentration was determined by using the modified method of o-toluidine /boric acid condensation method. Instead of heating in the presence of acetic acid in o-toluidine /boric acid condensation method, NaOCl, H₂O₂or ClC_(6)H₄CO₃H was used to stimulate the formation offufural derivative. The r values of calibration curve for glucose determinatiion by using H₂O₂, NaOCl, and ClC_(6)H₄CO₃H without heating were 0.97, 0.99 and 0.76, respectively. These results suggest that NaOCl might be the most effective condensation stimulator in glucose determination in terms of high r value when non-heating condensation method was used.

Bupivacaine is an amide-type local anesthetic widely used for regional anesthesia. Ropivacaine is developed as a less cardiotoxic alternatives to bupivacaine. In the present study, we have analyzed the effects of bupivacaine and ropivacaine on HERG currents expressed in Xenopus oocytes. Bupivacaine and ropivacaine(3∼1,000μM) blocked HERG currents in a concentration dependent manner. EC_(50) was 26.1±3.1μM(n_(R) 0.65±0.04) and 43.5±7.9μM(n_(H) 0.99±0.13) in bupivacaine and ropivacaine, respectively. Bupivacaine and ropivacaine did not affect the activation and deactivation kinetics of HERG channels. However, the drugs decreased the slope conductance measured from fully activated current-voltage relationship curves. These results suggest that bupivacaine and ropivacaine have a similarinhibitory effect on HERG channels, which could be a possible cellular mechanism of LQT or ventricular arrythmia by the drugs.
