There are several lasers available for office-based or suspension microlaryngoscopy laser procedures in the treatment of laryngeal diseases. Each has advantages and disadvantages given the depth of penetration per unit of power, absorption in water, spectral absorption characteristics, mode of delivery, safety, and cost. It is important to note that while the proper selection of indication of treatment based on a laser wavelength is critical, of equal importance is selecting the appropriate power setting, focal length (or spot size), and time of exposure. The photoangiolytic lasers precisely target hemoglobin within the microcirculation of the highly vascularized tissue and may have better hemostatic effects and preservation of surrounding normal tissue than the CO₂ laser. Although the choice of laser is purely theoretical and cannot be accurately concluded which parameters of laser (wattage and pulse width) were best to use, photoangiolytic laser surgery is safe and effective for specific laryngeal lesions. In this review, indications for photoangiolytic laser procedures for various laryngeal diseases, laser settings and surgical techniques for specific laryngeal lesions including sulcus vocalis, laryngeal dysplasia, and recurrent respiratory papillomatosis will be introduced. Pros and cons of in-office laser surgery using photoangiolytic laser and flexible CO₂ laser will also be addressed.

Objectives : The aim of this study is to review the effect of acupuncture/moxibustion on vitiligo. Methods : Using 5 databases(Pubmed, EMBASE, Cochrane Library, RISS, OASIS) clinical studies about effect of acupuncture/moxibustion on vitiligo were searched. Only randomized controlled trials(RCTs) were selected to analyze. Results : Total 235 studies were searched. After screening those studies 5 studies were selected from china and Iran. 3 studies used effective rate to measure the effect of acupuncture for vitiligo. 1 study used Vitiligo Area Scoring Index(VASI) and 1 study assessed 4 grade of repigmentation to prove acupuncture's effect on vitiligo. All studies showed repigmentation in acupuncture/moxibustion group. Adverse effects reported in the five studies were temporary erythema, itching, and dryness. Conclusions : These findings suggest that acupuncture and moxibustion can be considered a safe treatment for vitiligo. However, due to the small number of RCTs conducted on acupuncture and moxibustion for vitiligo, more RCTs should be conducted to confirm the effectiveness of acupuncture and moxibustion for vitiligo.

To certify the protective effect of herbal medicine against oxygen free radical-induced myocardiotoxicity, cytotoxicity was measured using MTT, LDH activity and Beating rate assay in the presence of Guaruhaebaekbanha-tang(GHBT) extracts or single constituents of this prescription. Myocardial toxicity was evaluated in neonatal rat myocardiocytes in cultures. In the present study, xanthine oxidase/hypoxanthine(XO/HX) resulted in a decrease in cell viability, increases in LDH activity in culture medium and decreases in beating rate in cultured myocardial cells. In the effect of GHBT extract, it showed the prevention from the XO/HX-induced cardiotoxicity by the increases of cell viability and beating rate as well as the decrease of LDH activity. In the protective effect of Fructus Trichosanthis(FT), Bulbus Allii Macrostemi(BAM) and Rhizoma Pinelliae(RP), all the extracts were significantly effective in the protection of XO/HX-induced cardiotoxocity in cultured myocardial cells by the increase of beating rate as well as th decrease of LDH activity. From these results, they show that XO/HX is cardiotoxic in cultured myocardial cells derived from neonatal rat, and it suggests that GHBT, FT, SAM, RP extracts are positively effective in the blocking in XO/HX-induced cardiotoxicity.

To investigate the contamination level and total dietary intake of Hg in common restaurant meals of Seoul area, 125 samples of 5 typical meals were collected and determined for their total Hg contents by flameless atomic absorption sepctrophotometry. The average concentrations of Hg were 0.186ppm in drained residues and 0.007ppm in fluids, in which two samples yeukkye-jang and bibim-bab from two sites showed such a high level of 20-30 times of mean values. The average amount of Hg per meal excluding the two samples was $79.6{\mu}g$ and it was not significantly different among different meals. The daily dietary intake of total Hg from 3 restaurant meals was estimated to be $239{\mu}g$, which was 5 times higher than the FAO/WHO limit of $42.9{\mu}g$.

MMP-2 and MMP-9, type IV collagenases which degrade basement membrane, have been known to play important roles in invasion and metastasis of tumor cells, In addition, they seem to be involved in cell differentiation, apoptosis, angiogenesis and immunity, etc. We immunohistochemically examined epithelial and stromal expressions of MMP-2 and MMP-9 in irritation fibroma, oral leukoplakia, and oral squamous cell carcinoma (OSCC) and have some results as follows: 1. Irritation fibromas, oral leukoplakias and OSCCs mostly showed increased expression of MMP-2 and MMP-9 in the epithelium and connective tissue compared with normal mucosa. 2. There was a significant difference in the epithelial expression of MMP-2 and MMP-9 between irritation fibroma and oral leukoplakia. 3. There was a significant difference in the epithelial and stromal expression of MMP-2 and MMP-9 between irritation fibroma and OSCC. 4. There was a significant difference in the stromal expression of MMP-9 between oral leukoplakia and OSCC. We concluded that rritation fibroma, oral leukoplakia and OSCC have somewhat different characteristics of MMP-2 and MMP-9 expressions, which perhaps result from different pathogenesis.
