Purpose : In order to study the effectiveness of East-West pain treatment on central poststroke pain(CPSP), we evaluated its effect on alleviation of pain and rehabilitation of CPSP Patients who were treated with electroacupuncture and west pain treatment for four weeks. Methods : Twenty four patients diagnosed by their pain characteristics of central pain from stroke were treated with sympathetic nerve block, gabapentin, amitriptyline, and electroacupuncture for four weeks. Pain intensity through the visual analogue scale(VAS), and improvements of mobility and rehabilitation through the modified Barthel index(MBI) and Rankin scale(RS), respectively, before and after pain treatment were also assessed. Results : VAS pain scores were significantly improved from 7.7±1.7 to 4.4±2.0 with pain treatment(p<0.05). In accordance with improvement of pain scores, RS and MBI scores were also improved from 2.88±0.95 to 2.13± 1.01 and from 83.0± 16.9 to 94.7±9.5(p<0.05), respectively, with pain treatment(p<0.05). Conclusions : It was suggested that the active pain treatment was contributed to the rehabilitation of CPSP patients, resulting in improvement of quality of life of CPSP patients. Futhermore, East pain treatment in combination with West pain treatment may be useful modality to alleviate CPSP.

Objectives The aim of this study is to evaluate the effect of light intensity variation on the polymerization rate of composite resin using IB system (the experimental equipment designed by DR. IB Lee) by which real-time volumetric change of composite can be measured. Methods Three commercial composite resins [Z100(Z!), AeliteFil(AF), SureFil(SF)] were photopolymerized with Variable Intensity Polymerizer unit (Bisco, U.S.A.) under the variable light intensity (75/150/225/300/375/450mW^2) during 20 sec. Polymerization shrinkage of samples was detected continuously by IB system during 110 sec and the rate of polymerization shrinkage was obtained by its shrinkage data. Peak time(P.T.) showing the maximum rate of polymerization shrinkage was used to compare the polymerization rate. Results Peak time decreased with increasing light intensity(p<0.05). Maximum rate of polymerization shrinkage increased with increasing light intensity(p<0.05). Statistical analysis revealed a significant positive correlation between peak time and inverse square root of the light intensity (AF:R=0.965, Z1:R=0.974, SF:R=0.927). Statistical analysis revealed a significant negative correlation between the maximum rate of polymerization shrinkage and peak time(AF:R=-0.933, Z1:R=-0.892, SF:R=-0.883), and a significant positive correlation between the maximum rate of polymerization shrinkage and square root of the light intensity(AF:R=0.988, Z1:R=0.974, SF:R=0.946). Discussion and Conclusions The polymerization rate of composite resins used in this study was proportional to the square root of light intensity. Maximum rate of polymerization shrinkage as well as peak time can be used to compare the polymerization rate. Real-time volume method using IB system can be a simple, alternative method to obtain the polymerization rate of composite resins.

본 연구에서는 배의 유용성 증명을 위한 일환으로 배의 화학성분을 분자수준에서 밝히고자 하였다. 이에 배 과피 MeOH 추출물을 용매분획하여 얻은 EtOAc-산성 분획과 EtOAc-중성분획을 대상으로 Sephadex LH-20, silica gel, 그리고 ODS colmn chromatography와 HPLC를 이용하여 정제 및 단리하였다. 그 결과, EtOAc-산성 분획과 EtOAc-중성 분획으로부터 각각 2종씩의 화합물을 단리하였다. 단리된 화합물 1-4는 1H- 및 13C-NMR 분석을 통하여 각각 (S)-(+)-2-cis-abscisic acid O-β-D-glucopyranosyl ester (화합물 1), 1-[4-O-β-D-glucopyranosyl]phenyl ethanone(piceoside, 화합물 2), β-sitosterol (화합물 3), 그리고 β-sitosteryl 3-O-β-D-glucopyranoside (화합물 4)로 동정되었다. 단리된 3종의 배당체 화합물(화합물 1, 2, 4)들은 본 연구에 의해 배로부터 처음 동정되었으며, 화합물 3은 추황배로부터 처음 동정되었다. 본 연구결과가 배 함유 성분연구는 물론 배의 기능성 해명 연구에도 추후 중요한 기초자료로 활용되길 기대한다. We isolated and identified antioxidants from acidic and neutral ethyl acetate fractions of the peel of pear (Pyrus pyrifolia N. cv. Chuhwangbae). We isolated 4 compounds from the methanol extract, by using 3 different types of column chromatography (Sephadex LH-20, silica gel, and octadecylsilane) and preparative HPLC. We identified the isolated compounds as (S)-(+)-2-cis-abscisic acid O-β-D-glucopyranosyl ester (compound 1), 1-[4-O-β-D-glucopyranosyl]phenyl ethanone (picroside, compound 2), β-sitosterol (compound 3), and β-sitosteryl 3-O-β-D-glucopyranoside (compound 4) by nuclear magnetic resonance analysis. We are the first to report the identification of compounds 1, 2, and 4 from pear.

DW-166HC (^(166)Holmium (^(166)Ho)-Chitosan complex) is a new radiopharmaceutic anticancer agent with a broad anti-tumorigenic spectrum, especially against human hepatic cancer. DW-166HC was evaluated for the appearance of micronucleus in polychromatic erythrocytes (PCEs) of mouse bone marrow cells after subcutaneous arid intravenous single administration. Bone marrow cells were prepared at 24 hr and 48 hr after DW-166HC-I (^(165)Ho-Chitosan complex : cold compound) administration and at 24 hr, 72 hr and 2 weeks after DW-166HC (^(166)Ho-Chitosan complex : hot compound) administration. The results showed there was no statistically significant increase of the numbers of PCEs with micronucleus in all DW-166HC-I administered groups compared with a negative control group but there was statistically significant increase of the numbers of PCEs with micronucleus at 24 hr arid 72 hr in all DW-166HC administered groups, which was recovered after 2 weeks from the drug administration. The results also showed the ratio of normochromatic erythrocytes (NCEs) to PCEs of all DW-166HC-I administered groups was not significantly different from that of a negative controi group but there was significant difference of this ratio at 24hr and 72 hr in all DW-166HC administered groups compared with that of negative group, which was also recovered after two weeks from the drug administration. These results suggested that DW-166HC-I may not cause any chromosomal damage but DW-166HC has in vivo mutagenic potential because of its radioactivity.

<P><B>Abstract</B></P> <P>Oxidative stress is closely associated with acetaminophen (APAP)-induced toxicity. Heme oxygenase-1 (HO-1), an antioxidant defense enzyme, has been shown to protect against oxidant-induced tissue injury. This study investigated whether sulforaphane (SFN), as a HO-1 inducer, plays a protective role against APAP hepatotoxicity <I>in vitro</I> and <I>in vivo</I>. Pretreatment of primary hepatocyte with SFN induced nuclear factor E2-factor related factor (Nrf2) target gene expression, especially HO-1 mRNA and protein expression, and suppressed APAP-induced glutathione (GSH) depletion and lipid peroxidation, which eventually leads to hepatocyte cell death. A comparable effect was observed in mice treated with APAP. Mice were treated with 300 mg/kg APAP 30 min after SFN (5 mg/kg) administration and were then sacrificed after 6 h. APAP alone caused severe liver injuries as characterized by increased plasma AST and ALT levels, GSH depletion, apoptosis, and 4-hydroxynonenal (4-HNE) formations. This APAP-induced liver damage was significantly attenuated by pretreatment with SFN. Furthermore, while hepatic reactive oxygen species (ROS) levels were increased by APAP exposure, pretreatment with SFN completely blocked ROS formation. These results suggest that SFN plays a protective role against APAP-mediated hepatotoxicity through antioxidant effects mediated by HO-1 induction. SFN has preventive action in oxidative stress-mediated liver injury.</P> <P><B>Highlights</B></P> <P> <UL> <LI> SFN pretreatment increases the cell viability against APAP-induced toxicity. </LI> <LI> SFN pretreatment protects depletion of cellular GSH after APAP treatment. </LI> <LI> SFN pretreatment enhances Nrf2 target gene expression, especially HO-1 after APAP treatment. </LI> <LI> SFN has protective effect against APAP overdose-induced liver injury <I>in vivo</I> model as well. </LI> </UL> </P>

Locoregional recurrence is the most common type of recurrence in surgical operation of gastric adenocarcinoma, and peritoneal dissemination is one of the most difficult problems in advanced gastric adenocarcinoma treatment. Because the peritoneal cavity is the most common site of the first recurrence after gastric cancer resection, intraperitoneal chemotherapy seems a logical choice for cancer chemotherapy. In this study, Mitomycin C (MMC)-activated charcoal (CH)-alginate (ALG) beads were prepared by the mixtures of CH particles adsorbed with MMC as an anti-cancer drug and aqueous alginate solution. The alginate is recognized as biodegradable, nontoxic, and biocompatible. The release of MMC from the beads in 0.1 M Tris buffer was stable and continuous until about 1 week. The MMC-CH-ALG beads can be applied in the peritoneal cavity for intraperitoneal chemotherapy since they provide a good adhesiveness on the tissue and controlled release pattern of the drugs.

Extrinsic dental stain may cause considerable cosmetic problems. Cigarette smoking can stain intraoral restorations, and the extent of stain accumulation will very depending. on the chemical properties of materials, surface roughness and surface treatment. This laboratory investigation was designed to simulate clinical stain accumulation from smoking using a smoking chamber. The purpose of this study was to determine and compare the extent of stain on some dental resins caused by cigarette smoking using a color difference meter(CIELAB color scale). Four kinds of light cured composite resins. (ALF, EST, TPH, Z10), three kinds of acrylic denture base resins(VRS, VSC, PS2), enamel, and dentin were investigated. Resin specimens of 3 mm thickness were made according to the manufacturer's instructions and were finally polished with Microcloth(Buehler). Half of the specimens were thermocycled between 5-55 ℃ for 1,000 cycles. Enamel and dentin specimens were made by ground and polished until flat and polished. L, a and b value of specimens were measured using a Colorimeter (Model TC-6FX, Tokyo Denshoku Co.) All the specimens were initially exposed to the smoking chamber for 4 hours and then exposed an additional 4 hours. Conditions in the smoking chamber were 37℃ and 100% relative humidity. It was filled with cigarette smoke. After removal from the smoking chamber, the surface of each specimen was wiped with tissue paper and then L, a and b value of specimens were measured. After 4 hours of exposure, the discoloration of dentin and enamel was most prominent(p<0.05), and the color change of heat cured acrylic resin was the least followed by light cured composite resin. Thermocycling did not affect the amount of discoloration. The discoloration after 8 hours of exposure was significantly(p<0.05) greater than that after 4 hours, and the amount of discoloration was more than five times greater. In conclusion, 8 hours storage in a smoking chamber caused significant color change(ΔΕ). The stains were smallest on heat cured acrylic resin and light cured composite resin.

The reconstruction of major head and neck defects must be an integral part of the overall cancer treatment plan. The priorities of surgical treatment of head and neck tumor are 1) local tumor control, 2) relief of pain, 3) avoidance of difficult dressing, 4) provision of oral continence, and 5) ability to swallow and manage saliva. The recent advances in reconstructive surgery including the development of musculocutaneous flaps and microvascular free tissue transfer have allowed the surgical restoration of head and neck tumor defects that previously were not possible. These techniques have provided the opportunity to undertake larger, more aggressive resection while at the same time permitting functional rehabilitation. The timing of reconstruction demands on the nature of the resection, the ability of the ablative and reconstructive teams to coordinate efforts, the overall health of the patients, the patient's needs and wishes. So, we report to emphasize current methods for restoring major head and neck tumor defects after tumor ablation, reviewing for the reconstructive operations, postoperative complications, and postoperative sequelae etc, of patients from Jan, 1990 to Dec, 1993.
