악성늑막삼출증 환자에서 임상증상을 호전시켜 삶의 질을 향상시키기 위한 여러 방법이 시도되고 있으나 어려운 점이 많다. 이전에 늑막유착을 위해 많이 사용하던 tetracycline은 생산이 중단되어 더 이상 사용하지 못하고 있다. 본 연구는 악성 늑막 삼출증 환자에서 흉강내에 탈크를 분무하여 늑막 유착의 효과을 연구함에 목적을 두고 전향적으로 조사하였다. 1995년 3월 부터 1997년 3월 까지 15명의 환자에서 흉강경을 이용하여 4 gm의 무균적이고 석면이 들어 있지 않은 100% 탈크을 분무하여 수술전과 수술후(평균 101일, 범위 25∼233일) 임상적, 방사선학적 비교 관찰하여 다음과 같은 결과을 얻었다. 1. 환자는 남자 6례, 여자 9례로 여자가 많았으며, 평균연령이 55.1세(범위 31∼74세)이었고, 원발성 종양은 폐암이 10례 유방암이 2례 간암, 위암, 미확인 선암이 각각 1례였다. 2. 수술전 늑막수에서 세포진 검사 양성률은 36%이었고 흉강경하 조직검사의 양성률은 100%였다. 3. 임상적으로 탈크 분무후 증상호전이 94%에서 관찰되었다. 4. 흉부 x-선 촬영상 술후 한달에서 94%의 늑막수의 재발이 없었다. 5. 술후 합병증으로는 창상감염과 호흡부전이 각각 1례씩 있었다. 결론적으로 악성늑막삼출증 환자에서 흉강경을 사용해 흉강내에 탈크을 분무하여 늑막유착을 유도하는 것이 매우 효과적인 방법으며 환자 선택에 있어 수술후 폐의 재팽창이 중요한 인자가 된다

Two experiments were carried out to study the effects of dietary energy level on nutrient digestion, nitrogen (N) utilization, growth performance, insulin-like growth factor-I (IGF-I), and insulin-like growth factor binding protein-3 (IGFBP-3) in plasma, liver and longissimus dorsi muscle in growing-finishing pigs. In experiment 1 (Exp 1), 15 castrated male pigs (Duroc${\times}$Landrace${\times}$Large White) (Body weight, BW, 55.6${\pm}$1.8 kg) were divided into three groups and fed rations containing 13.33, 14.87 and 17.35 MJ digestible energy (DE)/kg as treatments I, II and III, respectively, using soybean oil as an energy source. The experiment lasted 8 days and faecal and urinary samples were collected during the last 3 days. The results showed that the digestibility of dry matter (DM), energy and N was increased from treatments I to III (p<0.01). N-retention and N-retention rate were not influenced by dietary DE level (p>0.05). In experiment 2 (Exp 2), 36 female pigs (Duroc${\times}$Landrace${\times}$Large White) (BW 41.5${\pm}$3.8 kg) were divided into three groups. The pigs were fed with the same three rations used in Exp 1 for 60 days. At the end of Exp 2, eight pigs were selected from each group for blood sampling and 4 pigs for slaughter trial. The results indicated that average daily feed intake (ADFI) and N-intake were significantly decreased (p<0.01), and DE intake (p<0.01) and average daily gain (ADG) (p<0.05) were increased. IGF-I and IGFBP-3 in plasma were increased (p<0.05). No significant differences in IGF-I and IGFBP-3 in liver and longissimus dorsi muscle were found between different treatments. It was concluded that higher dietary DE level improved nutrient digestibility, ADG and feed/gain ratio when soybean oil was used as an energy source in the ration of growing-finishing pigs. No significant differences were found in Nretention and IGF-I and IGFBP-3 in liver and longissimus dorsi muscle between different treatments.

Purpose : To evaluate clinical and radiographic differential diagnosis between ameloblastoma and odontogenic keratocyst (OKC) using clinical data, plain radiographs, and CT. Materials and Methods: 25 cases of ameloblastoma and 44 cases of OKC diagnosed in biopsy, were selected from the files stored in Department of Oral and Maxillofacial Radiology, Seoul National University Dental Hospital from 1999 to 2001, and evaluated using following criteria: sex and age, location, shape, border to normal bone tissue, effect to adjacent tissues, homogeneity in the lumen of the lesion, response of the cortical bone, long-to-short length (LIS) ratio of the lesion, and expansion angle of the cortex. Results: Ameloblastoma and OKC were seen most frequently in third decades and no statistical significance was noted between both sexes. Ameloblastoma occurred most frequently in mandibular angle and ramus area (68%) and OKC at the maxillary molar (34.1 %), and mandibular angle and ramus area (43.2%). The root resorption of the adjacent teeth, mandibular canal displacement, and the impaction of teeth were seen more frequently in ameloblastoma than in OKC. The LIS ratio measured in CT was largest in maxillary OKC cases, followed by mandibular ameloblastoma, and mandibular OKC (1.2, 1.8 and 2.4 respectively). The expansion angle of the cortex shows a statistically significant difference between ameloblastoma (48.8°) and OKC (31.5°). Conclusion : The numeric morphology (LIS ratio) and expansion angle of the cortical bone of the lesion measured in computed tomography can be used to differentiate the ameloblastoma and odontogenic keratocyst.

Background : Asthma is a chronic inflammatory disorder under immunological influence. Shinbi-tang and Gamishinbi-tang are herbal decoctions used for treating asthma in traditional herbal medicine. Objective : To evaluate the effects of Shinbi-tang and Gamishinbi-tang on immune cell & serum OA-specific IgE in broncho-alveolar lavage fluid (BALF) in rat asthma model. Material and Methods : Rats were sensitized with ovalbumin (OA); at day 1 sensitized group and Shinbi-tang and Gamishinbi-tang groups were systemically immunized by subcutaneous injection of 1mg OA and 300mg of Al(OH)$_3$ in a total volume of 2ml. At the same time, 1 ml of 0.9% saline containing 6 x 10$^{9}$ B. pertussis bacilli was injected by i.p. 14 days after the systemic immunization, rats received local immunization by inhaling 0.9% saline aerosol containing 2%(wt/vol) OA. A day after local immunization, HAL fluid was collected from the rats. Rats were orally administered with each of Shinbi-tang and Gamishinbi-tang extract for 14 days from the day after local immunization. Lymphocyte, CD4+ T cell CD8+ T cell counts, CD4+/CD8+ ratio in BALF, change of serum OA-specific IgE level, CD4+ T cell CD8+ T cell percentages in the peripheral blood were measured and evaluated. Results : Shinbi-tang and Gamishinbi-tang showed an alleviating effect on asthmatic responses of rats. Shinbi-tang decreased total cell, lymphocyte, CD4+ T cell in BALF, serum OA-specific IgE level as compared with the control group. Gamishinbi-tang decreased total cell, lymphocyte, CD4+ T cell, and CD4+/CD8+ ratio in HALF as compared with the control group. CD4+/CD8+ ratio in HALF from Shinbi-tang group and serum OA-specific IgE level from Gamishinbi-tang group didn't show any significant variation from control group. CD8+ T cell in HALF, CD3+CD4+ T cell and CD3+CD8+ T cell percentages in peripheral blood showed no significant variation among groups. Conclusion : Shinbi-tang and Gamishinbi-tang alleviated asthmatic hypen-eactivity of the rat immune system through CD4+ T cell and serum IgE. Further the study of immune system modulating mechanism is expected.

본 연구에서는 여러 몰비의 망간과 철을 함유한 용액을 사용하여 담체인 모래 표면에 이들 산화물들이 동시에 코팅된 산화철 및 산화망간 코팅사(IMCS)를 제조하였으며, X-선 회절분석을 통하여 제조한 IMCS 표면의 광물종 규명과 이들에 의한 As(III) 산화 및 As(V) 흡착능을 평가하였다. 망간과 철을 동시에 코팅한 IMCS들에서의 철 및 망간의 총량은 단일금속용액으로 코팅시킨 담체(ICS 혹은 MCS)에 비하여 감소하였지만 코팅된 철산화물은 goethite와 magnetite의 혼합물 그리고 망간 산화물은 ${\gamma}-MnO_2$로서 매우 유사하였다. IMCS에 의한 As(V) 흡착량은 코팅된 망간보다는 철 함량에 의해 크게 영향을 받았다. 그리고 IMCS에 의한 As(V) 흡착량은 1가 및 2가 이온들로 이루어진 이온세기 화학종으로 이온세기를 고정하였을 때에는 큰 영향을 받지 않았으나 $PO_4\;^{3-}$와 같은 3가 화학종을 사용한 경우에는 크게 억제되었다. 망간만 코팅시켜 얻은 MCS의 경우, NaCl 및 $NaNO_3$와 같은 1가 이온세기 화학종이 존재하는 경우는 $PO_4\;^{3-}$와 같은 3가 이온세기 화학종이 존재하는 경우에서 보다 2배 이상의 산화효율을 나타내었다. 이에 반해 망간과 철이 함께 코팅된 7:3, 5:5, 3:7 몰비의 경우에는 $PO_4\;^{3-}$를 이온세기 화학종으로 사용한 경우가 다른 이온세기 화학종이 존재하는 경우에서 보다 오히려 As(III) 산화력이 높게 나타났는데 이것은 $PO_4\;^{3-}$가 As(V)와 IMCS 표면에 대한 경쟁흡착을 함에 따른 결과로 나타났다.

This study was conducted to determine the effects of dietary addition of tea saponins (TS) and soybean oil (SO) on fatty acid profile and gene expression of stearoyl-CoA desaturase (SCD) in longissimus dorsi (LD) muscle of growing lambs. Thirty-two Huzhou lambs were assigned to four dietary treatments in a $2{\times}2$ factorial arrangement with main effects of TS (0 or 3 g/d) and SO (0 or 30 g/kg of diet DM). The diet without additives was considered as NTNS (no TS or SO). After a feeding trial for 60 d, four lambs of each treatment were slaughtered to collect the samples of LD muscle. Percentage of trans-11 vaccenic acid was enhanced (p<0.05) in muscle of lambs fed TS and SO. The proportion of total conjugated linoleic acid (CLA) was increased (p<0.05) by SO, but decreased (p<0.05) by TS in LD muscle. The percentage of total saturated fatty acids in muscle was decreased (p<0.05) by addition of TS and SO, while addition of SO increased (p<0.05) the percentage of total polyunsaturated fatty acids. The ratio of cis-9, trans-11 CLA to tran-11 vaccenic acid was decreased (p<0.05) by TS, but increased (p<0.05) by SO. The same effects were observed in SCD mRNA expression. From these results it is indicated that including TS and SO in the diet of growing lambs affect the fatty acid profiles of LD muscle and that the proportion of cis-9, trans-11 CLA in the muscle influenced by TS and SO may be related to the SCD gene expression.

Purpose: Reduced heart rate variability significantly increases cardiovascular mortality. Metabolic syndrome increases the cardiac autonomic dysfunction. Recently, increasing cardiovascular mortality has been reported in patients with schizophrenia. This study was done to compare heart rate variability between adults with and without schizophrenia and to compare the relationship of heart rate variability to metabolic syndrome in hospitalized patients with schizophrenia. Methods: This was a descriptive and correlational study in which 719 adults without schizophrenia and 308 adults with schizophrenia took part between May and June 2008. We measured the following: five-minute heart rate variability; high-frequency, low-frequency, the ratio of low-frequency to high-frequency, and the Standard Deviation of all the normal RR intervals. Data was also collected on metabolic syndrome, abdominal obesity, triglycerides, HDL cholesterol, blood pressure and fasting glucose. Results: The Standard Deviation of all the normal RR intervals values of heart rate variability indices were $1.53{\pm}0.18$. The low-frequency and high-frequency values of heart rate variability indices were significantly higher in hospitalized patients with schizophrenia ($3.89{\pm}1.36$; $3.80{\pm}1.20$) than those in the healthy participants ($2.20{\pm}0.46$; $2.10{\pm}0.46$). There were no significant differences between the schizophrenic patients with and without metabolic syndrome. Conclusion: The results of this study indicate that schizophrenia patients have significantly lower cardiac autonomic control, but they have significantly higher low-frequency and high-frequency values than those of healthy adults. Use of antipsychotic drug may affect the autonomic nervous system in schizophrenic patients. Metabolic syndrome was not associated with cardiac autonomic control in schizophrenia patients.

Mung bean starch gel (Mook) and gel made from starch of cowpea are similar properties in texture. In order to elucidate the similarity between these two starch gels, some physicochemical properties of cowpea starch were compared with those of mung bean starch. Water bildings capacity of cowpea starch (183.6%) was a little low than that of mung bean starch (184.2%). The solobility, swelling power and optical transmitance of the cowpea starch showed a smiliar pattern to mung bean starch, but cowpea starch had a little lower solubility than mung bean starch. Amylogram of mung bean strach (4, 5, 6, 7%) shoved no peak viscosity but cowpea starch (4, 5, 6%) showed peak viscosity and both starches showed high viscosities when cooling. Cowpea and mung bean starches had the blue value of 0.41 and 0.47, the alkali number of 8.4 and 8.0, the amylose content of 30.5 and 32.1%, the molecular weight of amylose of 30,000 adn 29,258 and glucose unit per segment of amylopectin of 27.6 and 26.8 respectively. The shape of cowpea and mung bean strach granules were round and elliptical, and the mean vlalue of major axis, minor axis and the ratio of these were 20.7 and 21.8 ${\mu}{\textrm}{m}$, 14.6 and 14.4 ${\mu}{\textrm}{m}$ and 1.42 and 1.51, respectively. The extent of retrogradation determined by the glucoamylase digestion method and syneresis showed that cowpea starch gel was larger than that syneresis showed than cowpea starch gel was larger than that of mung bean starch gel. The redults of X-ray diffraction studies showed A pattern for two starches, Diffraction peak of gels disappeared with gelatinization of starches but that of two starch gels storaged for 2 days at 5$^{\circ}C$ showed a similar patterm.

Background: The DNA repair gene XRCC1 Arg399Gln gene polymorphism has been found to be implicated in the development of various cancers, including colorectal cancer (CRC), in different populations. We aimed to determine any association of this polymorphism with the risk of CRC in Kashmir. Materials and Methods: A total of 120 confirmed cases of CRC and 146 healthy cancer free controls from the Kashmiri population were included in this study. Genotyping was carried out by the polymerase chain reaction- restriction fragment length polymorphism (PCR-RFLP) method. Results: Genotype frequencies of XRCC1 Arg399Gln observed in controls were 34.2%, 42.5% and 23.3% for GG (Arg/Arg), GA (Arg/Gln), AA( Gln/Gln), respectively, and 28.3%, 66.7% and 5% in cases, with an odds ratio (OR)=5.7 and 95% confidence interval (CI) =2.3-14.1 (p=0.0001). No significant association of Arg399Gln SNP with any clinicopathological parameters of CRC was found. Conclusions: We found the protective role of 399Gln allele against risk to the development of CRC. The XRCC1 heterozygote status appears to be a strong risk factor for CRC development in the Kashmiri population.
