Background : In recent years, gonorrhea has been panedemic and remains one of the most commom STDs in the world, especially in developing countries. Objective & Methods: For the detection of a more effective therapeutic regimen and assessing the prevalence of PPNG, we have been trying to study the patients who have visited the VD Clinic of Choong-Ku Public Health Center in Seoul since 1980 by means of the chromogenic cephalosporin method. Results: In 1996, 139 strains of N. gonorrhoeae were isolated, among which 53(39.0%) were PPNG. Conclusion: Our results suggests that after a peak of 74.3% in 1993, the prevalence of PPNG in Seoul is gradually declining.

OBJECTIVE: The purpose of this study was to identify differences in orofacial muscle strength according to age and sex in healthy East Asian adults. DESIGN: A total of 382 subjects participated in this study (age range, 20–93 yrs). They were divided into two groups according to sex (male, n = 192; female, n = 190). The two groups were further divided on the basis of age into young (20–39 yrs), middle-aged (40–59 yrs), old (60–79 yrs), and very old (>80 yrs) groups. Assessments were performed using the Iowa Oral Performance Instrument. Measures included the anterior tongue elevation pressure, posterior tongue elevation pressure, buccodental pressure, and lip pressure. RESULTS: All measures were higher in the male than in the female subjects (P < 0.001). The male subjects showed noticeably lower tongue strength in the old and very old groups relative to the young and middle-aged groups (P < 0.01); the female subjects showed a similar result in the very old group as compared with all younger groups. CONCLUSIONS: Significant age-related differences in orofacial muscle strength were observed mainly of the tongue musculature. The male subjects had significantly lower tongue strength in the seventh decade or older as compared with the younger individuals, whereas in the female subjects, a similar result was noted, although tongue strength was not significantly lower until the ninth decade.

BACKGROUND: This study was conducted to investigate the agricultural product (Pulses, Lettuces, Pumpkins, Apples, Pears and Tangerines) in Korea, monitoring of cadmium (Cd) and lead (Pb) contaminations of agricultural products in cultivated areas and abandoned mine areas were investigated, and risk assessment was performed through dietary intake of agricultural products. METHODS AND RESULTS: The average contents of Cd and Pb ranged from 0.001 to 0.018 mg/kg and from 0.007 to 0.032 mg/kg respectively. The result was showed that contents of Cd and Pb did not exceed maximum residual levels established by CODEX except pumpkins and apples. The average daily intake were in the range of 1.06 × 10-3 to 4.76 × 10-2 μg/kg b.w./day at the mean and 95th percentile for Cd, 4.53 × 10-3 to 8.35 × 10-2 μg/kg b.w./day at the mean and 95th percentile for Pb for general population, based on the Korean public nutrition report 2008. The Hazard Index (HI) from the ratio analysis between daily exposure and safety level values was smaller than 1.0. CONCLUSION(s): This results demonstrated that human exposure to Cd and Pb through dietary intake of agricultural produces from abandoned mine areas might not cause adverse effect exceeding to those from non-contaminated areas.

The Hydrallgea macrophylla var. thunbergii (HMT) was widely cultivated for use in the manufacture of health foods such as tea, called Gamro-tea. In this study, HMT extract was fermented by using Weissella koreensis strain (WK), which was isolated from kimchi. Physico-chemical changes were monitored such as total acidity, reducing sugar and total phenolic content (TPC) during fermentation process. TEAC and ORAC assay were carried out to compare the antioxidant activity of hot water extract of HMT and fermented HMT extract. WK showed typical growth pattern on HMT extract medium at 35°C. Lag phase of WK last 6hr followed by the start of log phase at 8hr. Maximum growth was achieved at 24 hr. Total acidity increased linearly until the fermentation time of 18 hr and reducing sugar content was decreased from 2.88% to 2.06% at 24 hr fermentation. TPC was increased at fermentation time until 72 hr. Antioxidant activity was measured with TEAC assay and ORAC assay using 72 hr fermented HMT extract. TEAC evaluated electron transfer reaction and ORAC evaluated hydrogen atom transfer reaction. WK fermentation improved TEAC and ORAC value of HMT extract significantly.

<P><B>Abstract</B></P> <P>Implantable electronic medical devices (IEMDs) can potentially be used to solve various clinical problems including the monitoring of chronic diseases and electro-organ transplantation. Several recently introduced techniques based on implantable devices that exploit novel metal- or carbon-based hybrid materials are biocompatible owing to their encapsulation in nontoxic polymers. However, such techniques limit the correct functioning of implantable devices, resulting in frequent replacement, difficult miniaturization, and inflammatory side effects in the body. Here, we describe a new technique for application to IEMDs that is capable of providing energy storage using the natural ions of body fluids as electrolytes in a supercapacitor (or ultracapacitor). The system is constructed with a solar cell for energy harvesting and a supercapacitor for energy storage. We assembled IEMDs with two biocompatible electrodes, specifically, MnO<SUB>2</SUB> nanoparticles affixed to multi-walled carbon nanotubes as the positive electrodes and phosphidated activated carbon as the negative electrodes. From the obtained result, this work can be further extended to the use of rats. This technique avoids the problems of performance degradation and toxicity that normally limits the reaction that is permissible in extracellular fluid. We present this concept schematically. The two biocompatible electrodes were successfully implanted into the subcutaneous layer of a rat's skin with both electrodes showing stable performance in use as parts of a supercapacitor. These findings establish a platform for potential biocompatible materials for implantable energy storage devices.</P> <P><B>Graphical abstract</B></P> <P>[DISPLAY OMISSION]</P>
