An optional ingredient Perilla Seed paste was adopted to improve the quality of Yulmoo Mul-kimchi during fermentation. The final weight percentage of perilla seed paste in Yulmoo Mul-kimchi was adjusted to 0, 10, 20, 30, and 40% per water respectively. Chemical and sensory characteristics were determined during fermentation at 10℃ for 25 days. The effect was varied depending on the amounts of perilla seed paste, but Yulmoo Mul-kimchi fermented with 20% perilla seed paste was most favored for color, smell, sour taste, carbonated taste, texture and overall acceptability in the sensory evaluation. The pH decreased with the increase of total acidity. The total vitamin C content increased initially to the certain level at a certain time of fermentation depending on the level of perilla seed paste, and then decreased later. In case of reducing sugar, the 20% treatment showed the highest content. Turbidity values were generally increased in all samples during fermentation, even though the extents were limited. Total plate count and the number of lactic acid bacteria were gradually increased and then decreased showing the maximum microbial counts during fermentation. The optimum levels of perilla seed paste in Yulmoo Mul-kimchi obtained through experiments were between 20 and 30% of added water content, preferably 20% for color, fermentation-retarding effect, and sensory taste of the product.

PGE_2 has both anabolic and catabolic activities. Excess levels of PGE_2 have been implicated in a number of pathological states associated with bone loss such as a number of chronic inflammatory conditions such as periodontal disease and rheumatoid arthritis. PGE_2 and other arachidonic acid metabolites have been shown to be potent stimulators of osteoclastic bone resorption in organ culture. The anabolic effects of PGE_2 were first noticed when an increase in periosteal woven bone formation was seen after the infusion of PGE_2 into infants in order to prevent closure of the ductus arteriosus. The cellular basis for the catabolic actions of PGE_2 has been well characterized. PGE_2 increases osteoclast recruitment in bone marrow cell cultures. PGE_2 also has a direct action on osteoclast serving to inhibit activity and can also indirectly activate osteoclast via other cells in the vicinity, presumably osteoblast. PKC was reported to be involved in the action of osteotropic hormones. PTH primarily affects osteoblasts and increases irrtracellular cAMP level, and PTH-stimulated osteoblasts may produce and release the substances that activate osteoclasts. PKC may mediate the action of PTH in osteoblasts. Moreover, PKC increase the number of receptors for 1,25-(OH)_2D_3 in the osteoblasts. The purpose of this paper is to study the actions of PGE_2 and PMA on osteoblastic clone MC3T3E1 cells. The effect of PMA and PGE_2 on the induction of alkaline phosphatase(ALP) was investigated in osteoblastic clone MC3T3E1 cells clutured in medium containing 04% fetal bovine serum. PMA and PGE_2 stimulated ALP activity and MTT assay in the cells in a dose-dependent manner at concentrations of 10-500ng/ml. Cycloheximide, protein synthesis inhibitor, inhibited the stimulative effect of PGE_2 and PMA on ALP activiy in the cells. PGE_2 also increased the intracellular cAMP content in a dose-dependent fashion with a maximal effect at 500ng/ml. Our present results suggest that PGE_2 stimulate the differentiation of osteooblasts and are involved in bone formation in vivo, as well as in bone resorption.

Helicobacter pylori is the major cause of histologic chronic gastritis and is strongly associated with peptic ulcer disease, gastric cancer and lymphoma. Several recommendations for the management of the Helicobacter pylori infection have been developed. However, there has been no clear therapeutic regimen for the optimal treatment of Helicobacter pylori infection. This study was desinged to evaluate the eradication rate and the ulcer healing rate of the triple regimen with low-dose clarithromycin(0.5g/day) in peptic ulcer patients. Forty three patients with gastric ulcer(n=15) and duodenal ulcer(n=28) were enrolled. The patients were treated either with omeprazole 20mg b.i.d. amoxicillin 0.5g b.i.d. and clarithromycin 250mg b.i.d. (low-dose regimen group, n=29) or with omeprazole 20mg b.i.d., amoxicillin 1.0g b.i.d. and clarithromycin 0.5g b.i.d.(high-dose regimen group, n= 14) for 2 weeks. After 4 weeks, the patients were evaluated for the eradication of Helicobacter pylori and the healing of ulcer. And gastritis scores according to the Sydney system were evaluated before and after 4 weeks from the end of the triple regimen. There was no significant difference in the eradication rate and the ulcer healing rate between the low-dose regimen group, group and the high-does regimen group. In the low-does regimen group, the mean initial scores of chronic inflammation and activity were decreased after the eradication of Helicobacter pylori. In conclusion, the low-dose triple regimen is as effective as the high-dose triple regimen on the eradication of Helicobacter pylori and the ulcer healing rate in peptic ulcer disease.

The application of Dongchimi liquid to Naengmyon broth to improve its eating quality was scientifically explored by reviewing the quality of the product properties. Primarily, the optimum fermentation conditions for Dongchimi from which the liquid portion was extracted were pursued and the optimum mixing ratio sought on the basis of the product physicochemical properties. The liquid portions, periodically extracted from Dongchimi at intervals of two or five days, during fermentation at 10℃, were added to Naengmyon broth. The treatments were prepared at three levels namely, basic broth only ('A') and with ratios of Dongchimi liquid to basic broth of 3:7 (v/v, 'B') and 5:5 (v/v, 'C'). As a typical phenomenon of kimchi fermentation, a gradual decrease in the pH with increasing total acidity was observed as the fermentation of the Dongchimi progressed. At 10V, the optimum ripening was obtained from day 8, and continued until day 15, when the pH was maintained at about 3.8 to 4.0. The total vitamin C and reducing sugar contents increased until the 13th-day of fermentation, but then decreased thereafter. The turbidity and solid content of the Dongchimi liquid increased with progression of the fermentation. With respect to the color values, the lighmess (L) decreased, with increases in the redness (a), yellowness (b) and total color difference (ΔE) during fermentation. Most of these observed phenomena for the Naengmyon broth substituted with 30% (Treatment 'A') and 50% (Treatment 'B') Dongchimi liquid, with different storage periods, confirmed the previous fermentation patterns of Dongchimi. A decrease in the pH with increasing total acidity, as well as gradual increases in the total vitamin C and reducing sugars (glucose and fructose) up to the 13th-day of fermentation were accompanied by subsequent declining patterns. The turbidity and solid content of the mixed broth also increased with increasing Dongchimi liquid fermentation period. With respect to the color of the tnixed broth, the lightness was decreased, while the redness, yellowness and total color difference increased with increasing Dongchimi liquid fermentation period. It was also proven that the addition of slightly over-ripened Dongchimi liquid to the Naengmyon broth was more preferable.

The application of Dongchimi liquid into Naengmyon broth for the improved eating quality of Naengrmyon was scientifically explored by reviewing the quality properties of the product. Primarily, the optimum fermentation conditions for Dongchimi from which the liquid portion was extracted were pursued and the optimum mixing ratio was sought on the basis of sensory and microbiological properties of the product. The liquid portions which had been periodically extracted from Dongclimi at intervals of two or five days during fermentation at l0℃ were added to Naengmyon broth. The treatments were prepared with three levels, namely, basic broth only('A') and the ratios of 3:7(v/v, B') and 5:5(v/v, 'C') of Dongchinti liquid and basic broth, respectively. According to assessments of Dongchimi liquid on taste and intensity based on sensory analyses, the organoleptic factors such as color, smell, sour taste, carbonated taste, and overall acceptability were given higher values from day I1 to day 17 in all items. As for the assessment of Dongchinti liquid on intensity, color, sour odor, moldy odor, and carbonated taste have shown the increasing scores during with high intensities while those for clearness has stayed low. Most of the phenomena observed from the Naengnlvon broth substituted with 30%(Treatment 'A') and 50% (Treatment 'B') of Dongchirni liquids with different storage periods ensued much of the previous fermentation pattern of Dongchinti itself. Organoleptic assessment on taste and its intensity showed that better(the best) scores could be obtained at between day 16~25(17) and 13~20(15) for Treatments A and B, respectively, The intensity scores of taste for color, smell, carbonated taste, sour taste, and mouthfeel were increased while those for clearness, palatability, and meaty ones were decreased with lapse of fermentation. The numbers of total cell and lactic acid bacterial counts of Dongchimi has increased until day 13 and then decreased in the later stages. Total cell count and lactic acid bacterial counts of Naengmyon broth also increased until the 13th day and then they began to decrease. It was also proven that slightly over-ripened Dongchimi liquid was more preferable for adding into Naengmyon broth. Granting the optimum ripening period of Dongchimi liquid itself to be 13 days. both Treatment A and Treatment B were evenly favored using Dongchimi liquids slightly over-ripened at days 13 to 17. However, Treatment A was more favored than Treatment B when Dongchimi liquid over-ripened for 20 to 26 days was used.

Recently, many reports suggested that warm water swim-stress induces an opioid-analgesia, while cold water swim-stress produces a nonopioid form of analgesia. And Hong et. al. reported that the increase of plasma corticosterone (p-CS) in response to swim-stress at 20℃(20-SS) was significantly attenuated by swim-stress at 4℃ (4-SS) was affected by CL but markedly suppressed by BA. In this paper, the influences of CL-500㎍/㎏ and BA-5㎎/㎏ on the change of p-CS in response to 20-SS or 4-SS were studied in male mice comparing with those of morphine and naloxone. The 20-SS induced increase of p-CS was significantly inhibited by CL and BA, respectively, while the 4-SS induced increase was not affected by CL but markedly inhibited by BA. And the 20-SS or 4-SS induced increase of p-CS was slightly inhibited by naloxone,2mg/kg but not affected by morphine, 2㎎/㎏. The increase of p-SS in response to three times repeated 20-SS or 4-SS with one hour interval was little affected by B-pretreatment, but CL-pretreatment slightly attenuated the 4-SS induced increase of p-CS and significantly inhibited the 20-SS induced increase. The increase of p-CS induced by the repeated SS was little affected by the treatment of BA 30 minutes before the last SS, but the such treatment of CL slightly attenuated the p-CS increase induced by the repeated 20-SS but significantly enhanced the p-CS increase by the repeated the repeated 4-SS. And during the experiment of repeated 4-SS, 55.6% of mice pretreated with BA were drowned. The results demonstrate that there are some pharmacological differences between the mechanisms of hypothalamo-adenohypophysial responses to 20-SS and 4-SS, respectively.

The malignant tumor in childhood is one of the main causes of children s death due to disease. The traditional treatment for the malignancy is known for the radiation therapy and the chemical therapy or both. However, the treatments tend to induce intraoral complications. Different from adults, almost all children on cancer therapy are expected to have dental complications, because their permanent teeth are on the developmental stage. The degree of dental complication depends on the patient's age, type of chemical and other factors-radiation dose and frequency. In this report, 3 children who had experienced the anti-cancer therapy on their age between 1 and 4 years were selected and dental complications were examined. The children have chance for the various oral complications including the developmental problems such as agenesis, microdontia and hypoplasia of the teeth. Therefore, it's important to understand the side-effects of anticancer therapy during the permanent teeth had been developmental stage in young patients. Also, oral health care specialists, including pediatric and hospital dentist can support the oncology team by providing basic oral care, implementing oral care protocols, delivering emergency dental treatment undergoing anticancer treatment. 소아기의 악성 종양은 질병으로 인한 소아 사망의 가장 흔한 원인이다. 이에 대한 대표적인 치료 방법으로 항암 화학 요법과 방사선 요법의 단독 사용 혹은 이들의 병용을 들 수 있다. 그러나 이러한 치료 방법은 다양한 구강 내 합병증을 동반한다. 성인과 달리 소아 환자는 항암치료 시기에 일부 영구치가 활발한 발육단계에 있으므로 발육중인 치아에 치과적 합병증이 예상된다. 치과적 합병증의 정도는 화학약물의 종류, 용량 및 방사선 조사 빈도와 치료 당시 환자의 나이에 따라 달라진다. 본 증례들에서는 특정 영구치의 발육단계에 있는 만 1-4세경에 종양의 치료를 위해 항암 화학 요법과 방사선 치료를 받은 어린이 3명을 대상으로 치료 내용과 치아 발육 상황을 검토해 보았다. 이환된 치아의 수나 그 정도에 차이는 있으나, 각각의 환자에서 영구치 치배의 선천 결손, 왜소치, 치근 저형성 등 발육장애 관련 소견이 관찰되었다. 항암치료를 받은 병력이 있는 소아에 있어서 항암치료 이후에 나타날 수 있는 일반적인 구강 합병증 이외에 발육시기 동안 치아에 미치는 영향을 고려하여, 공간 문제를 포함하여 향후 발생 할 수 있는 다앙한 문제점 예방을 위한 장기적인 관찰과 관리가 필요할 것으로 생각된다.
