Background: Anaplastic lymphoma kinase (ALK) gene rearrangement in non-small cell lung cancer (NSCLC) has been intensively studied. The gold standard for ALK detection is FISH, but this is not routinely conducted in clinical practice, so that the IHC method has a role. The aim of this study was to identify the incidence of ALK rearrangement and risk or prognostic factors for ALK positivity using both of IHC and FISH methods. Materials and Methods: From January 2008 to December 2012, 267 completely resected NSCLC patients in Chiang Mai University Hospital were enrolled in this study. Clinical and pathological variables and outcomes of treatment were retrospectively reviewed. IHC and FISH were used to evaluate ALK rearrangement. Sensitivity and specificity of IHC were analyzed. Multivariable analysis was used to identify clinico-pathological correlations with positive results of IHC and clinical outcomes. Results: Twenty-two (8.2%) of 267 specimens were IHC-positive for ALK with intense cytoplasmic staining, whereas only 10 (3.8%) were FISH-positive. Sensitivity, specificity and the positive likelihood ratio with IHC were 80.0%, 94.9%, and 15.8 respectively. Age less than 55 years (RR 4.4, 95%CI 1.78-10.73, p value=0.001) and presence of visceral pleural invasion (VPI) (RR 2.9, 95%CI 1.21-6.78, p value =0.017) were identified as risk factors for ALK rearrangement with FISH. There were no statistically significant differences in other clinical and pathological variables. ALK rearrangement was not a prognostic factor for tumor recurrence or overall survival. Conclusions: The incidences of ALK positivity in completely resected NSCLCs in northern Thailand were 8.2% by IHC and 3.8% by FISH. IHC with mouse monoclonal, Ventana D5F3 antibody can be used as a screening tool before FISH method because of high specificity and high positive likelihood ratio. Age less than 55 years and VPI are risk factors for ALK positivity.

The purpose of this study was to investigate the obesity and state of dietary intake of 216 young Korean females, and the influence of $\beta$-II, III Adrenergic receptor (AR) gene polymorphism upon obesity and dietary intake. The average weight, height and BMI of the subjects were 160 cm, 54 kg, and 20.9 kg/$m^2$, respectively. The average triceps skinfold thickness, waist circumference, hip circumference and WHR were 21.7mm, 73.1cm, 93.3cm and 0.78, respectively. The results of body composition measurement using bioimpedance method, average body fluid, body protein, mineral mass and body fat were 29.271, 7.22 kg, 6.79 kg and 19.16 kg, respectively. A dietary survey was conducted using 24-hour recall method. Average calorie intake was 1621 ㎉, which is 81% of Korean RDA. We detected 182 (84.3%) Gln27 (QQ) homozygotes and 34 (15.7%) Gln27Glu (QE) heterozygotes for $\beta$-II AR polymorphism. For $\beta$-III AR polymorphism, we detected 163 (75.5%) Trp64 (WW) and 53 (24.5%) Trp 64Arg (WR). The results of comparing of obesity by $\beta$-II AR gene polymorphism, obesity index and BMI of QE type were slightly higher than those of the QQ type. For $\beta$-III AR gene polymorphism, the mean BMI, obesity index, fat mass and percent body fat (%) of the WR type were significantly higher than those of the WW type (p < 0.05). These findings suggest that genetic variability in the human $\beta$-III AR is associated with obesity among young Korean females. We also evaluated the effect of the simultaneous presence of the $\beta$-II AR and $\beta$-III AR polymorphism on obesity. We found that the BMI and obesity index of the mutant type in both $\beta$-II AR and $\beta$-III AR were significantly higher than those of the type that has only one gene mutation or has no mutation (p < 0.05), indicating a synergistic effect of $\beta$-II AR and $\beta$-III AR polymorphism on obesity. No association was found between $\beta$-II Ad or $\beta$-III AR polymorphism and dietary intake.

Purpose: We evaluated the motion-induced dosimetric effects on the field-in-field (FIF) technique for whole-breast irradiation (WBI) using actual patient organ motion data obtained from cine electronic portal imaging device (cine EPID) images during treatment. Materials and Methods: Ten breast cancer patients who received WBI after breast-conserving surgery were selected. The static FIF (SFIF) plan involved the application of two parallel opposing tangential and boost FIFs. To obtain the amplitude of the internal organ motion during treatment, cine EPID images were acquired five times for each patient. The outside contour of the breast (OCB) and chest wall (CW) contour were tracked using in-house motion analysis software. Intrafractional organ motion was analyzed. The dynamic FIF (DFIF) reflecting intrafractional organ motion incorporated into the SFIF plan was calculated and compared with the SFIF in terms of the dose homogeneity index (DHI_90/10) for the target and V₂₀ for the ipsilateral lung. Results: The average motion amplitudes along the X and Y directions were 1.84±1.09 mm and 0.69±0.50 mm for OCB and 1.88±1.07 mm and 1.66±1.49 mm for CW, respectively. The maximum motion amplitudes along the X and Y directions were 5.53 and 2.08 mm for OCB and 5.22 and 6.79 mm for CW, respectively. Significant differences in DHI_90/10 values were observed between SFIF and DFIF (0.94 vs 0.95, P<0.05) in statistical analysis. The average V₂₀ for the lung in the DFIF was slightly higher than that of the SFIF in statistical analysis (19.21 vs 19.00, P<0.05). Conclusion: Our findings indicate that the FIF technique can form a safe and effective treatment method for WBI. Regular monitoring using cine EPID images can be effective in reducing motion-induced dosimetric errors.

This study was carried out to evaluate the relationship between the biological lead exposure indices and air lead concentrations measured by personal air samplers. The 72 occupationally lead exposed workers were observed and the bioiogical lead Exposure indices chosen for this study were blood lead(PbB), urine lead(PbU), zinc protoporphyrin in whole blood(ZPP), $\delta$-aminolevulinic acid in urine(ALAU), $\delta$-aminolevulinic acid dehydratase activity (ALAD), coproporphyrin in urine(CPU) and hemoglobin(Hb). The workers were divided into four groups by air lead concentrations: Group I; under $0.05mg/m^3$, Group II; $0.05-0.10mg/m^3$, Group III; $0.10-0.15mg/m^3$ and Group IV; and over $0.15mg/m^3$. For evaluation the relationship between the biological lead exposure indices and air lead concentrations was used as correlation coefficients. The results obtained were as follows: 1. In Group I, II, III and IV, the mean value of PbB were $25.45{\pm}1.84{\mu}g/dl,\;27.87{\pm}3.53{\mu}g/dl,\;31.21{\pm}1.76{\mu}g/dl\;and\;47.02{\pm}13.96{\mu}g/dl$. Between Group IV and other groups showed statistically significant difference(p<0.05). 2. There was an increasing tendency of PbB, PbU, ALAU and ZPP according to the increase the mean air lead concentration, while ALAD has decreasing tendency. CPU and Hb did not show any constant tendency. 3. Correlation coefficients between PbB, PbU, ZPP, ALAU, ALAD, CPU, Hb and air lead concentration were 0.95, 0.83, 0.89, 0.72, -0.83, 0.51 and -0.45 respectively, and regression coefficient between PbB(Y) and PbA(X) was Y=126.8746X+16.9996(p<0.01).

Tetralogy of Fallot is a cyanotic congenital heart disease characterized by large ventricular septal defect[VSD] and stenosis of right ventricular outflow tract[RVOT] and the degree of RVOT stenosis and the state of pulmonary arteries are the major determinant of prognosis of this anomaly after operation. The sum of blood flow through RVOT and collateral flow from systemic arteries determine the total pulmonary blood flow and it is drained to left atrium and left ventricle. Therefore the degree of development of left ventricle not only reflects pulmonary blood flow and the status of peripheral pulmonary arteries but also affects postoperative prognosis as a systemic ventricle. In this article, left ventricular volume and its influence on postoperative cardiac function in tetralogy of Fallot were studied in 34 patients operated on at Department of Thoracic and Cardiovascular Surgery, Seoul National University Hospital in 1985. Mean age of the patients was 5 1/12*3 9/12 years[range 9/12 - 14 8/12 years], mean body surface area[BSA] 0.65*0.20m2[range 0.38 - 1.22m2], mean body weight 15.6k6.48kg[range 7.0 - 36kg]and mean hematocrit 50.6*9.77%[range 32.0 - 73.5%]. Left ventricular end-diastolic volume[LVEDV] of them were from 11.2 to 113cc and there was a good linear correlation between BSA[m2, X]and LVEDV[cc, Y][Y= - 20.0+923x, r= 0.84, p < 0.005]. Mean LVEDV/m2 was [57.6 * 18.3 cc / m2[range 28.7 - 95.8 cc / m2] and there was a significant reduction of volume compared with normal value. As body surface increases, there was a increasing tendency in LVEDV/m2 but there was no statistical significance. Mean total amount of postoperatively infused dopamine in these 33 patients[except one who expired postoperatively] was 65.6*74.5mg / kg and it was 40.6*44.0mg / kg in routine RVOT widening group [Group I] and 205*49.3mg / kg in transannular RVOT widening group[Group II]. There was a statistically significant difference between two groups. In group I patients there was a good linear inverse correlation between dopamine total amount[mg / kg, Y] and LV volume[cc / m2, X] [Y = 150 - 1.89 X, r = - 0. 77, p < 0.005]. But there were no correlations between dopamine total amount and Hct, cardiopulmonary bypass time and aorta cross clamp time. In conclusion, the patient with small preoperative left ventricular volume required more amount of dopamine as an inotropic agent for the maintenance of a cardiac function in postoperative period. But this is a result of immediate postoperative period and does not reflect the long term effect of left ventricular volume in tetralogy of Fallot. There must be more study for the evaluation of its long term effect.

This study was to evaluate the usefulness of a programmed reproductive management including Presynch-Ovsynch-Resynch protocol in lactating dairy cows. Nine hundred and thirty four cows calved during February to May 2008 were used for this study. Cows received im injections of 25 mg $PGF_{2{\alpha}}$ at $45{\pm}3$ and $59{\pm}3$ days in milk (DIM). Fourteen days later, Ovsynch was initiated with an im injection of $100\;{\mu}g$ GnRH ($73{\pm}3$ DIM), 25 mg $PGF_{2{\alpha}}$ 7 days later ($80{\pm}3$ DIM), $100\;{\mu}g$ GnRH 56 h later and timed artificial insemination (TAI) 16 h after the GnRH injection. Cows showed estrus during the Presynch-Ovsynch, were inseminated artificially according to am-pm rule. Pregnancy was determined on 32 days after AI using ultrasonography. Cows diagnosed pregnant were re-examined for pregnancy by rectal palpation at 60 days after AI. Non-pregnant cows were resynchronized by receiving $100\;{\mu}g$ GnRH, 25 mg $PGF_{2{\alpha}}$ 7 days later, $100\;{\mu}g$ GnRH 56 h later and TAI 16 h after. Cows with estrus since the first AI before the completion of Resynch protocol were also inseminated artificially according to am-pm rule. Pregnancy was determined by the same manner as following the first AI. Fifty five percents of the cows treated showed estrus and received AI before completion of the Presynch-Ovsynch protocol, while 45% received TAI, regardless of estrus exhibition following the completion of the protocol. The pregnancy rate following the first AI was higher in cows that showed estrus and received AI (43.3 and 38.5%) during the Presynch-Ovsynch than cows with TAI (34.6 and 29.6%) on 32 and 60 days after AI (P < 0.01). Sixty six percents of cows diagnosed non-pregnant following the first AI showed estrus before the completion of Resynch protocol and received AI, while 34% received TAI, regardless of estrus exhibition following the completion of the protocol. The pregnancy rate following the second AI was higher in cows that showed estrus before the completion of Resynch protocol and received AI (40.2 and 36.8%) than cows with TAI (21.2 and 18.2%) on 32 and 60 days after AI (P < 0.01). The cumulative pregnancy rates following the first and second AIs were 60.8 and 53.9% on 32 and 60 days after AI, respectively. These data suggest that inclusion of Presynch-Ovsynch-Resynch protocol and estrus detection into the programmed reproductive management might be an alternative option to control dairy cattle breeding.

The determination of peripheral nerve conduction velocity is an important part to electrodiagnosis. Its value as neurophysiologic investigative procedure has been known for many years but normal value of digital nerve was not reported in Korea. To evaluate of digital nerve conduction velocity of median nerve for obtain clinically useful reference value and compare difference in each fingers. 71 normal volunteers(age, 19-65 years; 142 hands) examined who has no history of peripheral neuropathy, diabetic mellitus, chronic renal failure, endocrine disorders, anti-cancer medicine, anti-tubercle medicine, alcoholism, trauma, radiculopathy. Nicolet Viking II was use for detected conduction velocity and amplitude of digital nerves in median nerve. Data analysis was performed using SPSS. Descriptive analysis was used for obtain mean and standard deviation, ANOVA was used to compare each fingers and independent t-test was used to compare between Rt and Lt side also compare between different in genders. Conduction velocity of the right thumb was 49.77m/sec, index finger was 56.80m/sec, middle finger was 56.15m/sec and ring finger was 53.38m/sec. The left thumb was 50.48m/sec, index finger was 56.76m/sec, middle finger was 55.99m/sec and ring finger was 53.23m/sec. Amplitude of the right thumb was $64.30{\mu}V$, index finger was $73.95{\mu}V$, middle finger was $77.97{\mu}V$ and ring finger was $43.92{\mu}V$. The left thumb was $74.21{\mu}V$, index finger was $85.72{\mu}V$, middle finger was $88.06{\mu}V$ and ring finger was $47.28{\mu}V$. There were significantly difference between thumb, index, middle and ring fingers(p<.01) but there were no statistically difference between conduction velocity and amplitude of index and middle fingers(p>.01). The conduction velocity of index finger are faster than other fingers and amplitude of middle finger are greater than other fingers. The present results revealed that electodiagnosis can easily perform in index and middle finger for digital nerve of median nerve study.

Objectives : To observe the effect of acupuncture treatment and western medical treatment on frozen shoulder patients. Methods : 39 voluntary patients were randomly assigned to the Eastern treatment group(E group, n=22) and the Western treatment group(W group, n=17). The E group received acupuncture treatment on LI15, TE14, GB21 and Master Dong's acupuncture points, Shin-gwan and Gyun-joong, twice a week for 4 weeks. The W group received suprascapular nerve block, subacromial injection and trigger point injection, twice a week for 4 weeks. Both groups were instructed to practice self exercise during their daily lives. Evaluations were made before treatment and after treatment using Constant Shoulder Assessment(CSA), Shoulder Pain and Disability Index(SPADI) and the patient's satisfaction concerning the treatment was measured by Visual Analogue Scale(VAS). The obtained data were analyzed and compared. Results : The E group showed significant improvement(p<0.05) according to the CSA and SPADI. The patient's satisfaction scored 5.67 on a scale of 10. The W group showed significant improvement(p<0.05) according to the CSA and SPADI. The patient's satisfaction scored 7.73. But the difference between the two groups were insignificant according to CSA and SPADI. Conclusion : Both acupuncture and nerve block treatment significantly improved frozen shoulder. But the difference of the two treatments was insignificant.

The purpose of this study is to develop transgenic cell line expressing targeted human granulocyte colony stimulating factor (hGCSF) and green fluorescence protein (GFP) genes as well as production of Somatic Cell Nuclear Transfer (SCNT) embryos derived from co-expressed transgenic donor cells. Constructed pPiggy-mWAP-hGCSF-EF1-GFP vector was chemically transfected into bovine fetus cells and then, only GFP expressed cells were selected as donor cells for SCNT. Cleavage and blastocyst rates of parthenogenetic, SCNT embryos using non-TG cell and hGCSF-GFP dual expressed SCNT embryos were examined (cleavage rate: $78.0{\pm}2.8$ vs. $73.1{\pm}3.2$ vs. $70.4{\pm}4.3%$, developmental rate: $27.2{\pm}3.2$ vs. $21.9{\pm}3.1$ vs. $17.0{\pm}2.9%$). Result indicated that cleavage and blastocyst rates of TG embryos were significantly lower (P<0.05) than those of parthenogenetic and non-TG embryos, respectively. In this study, we successfully produced hGCSF-GFP dual expressed SCNT embryos and cryopreserved to produce transgenic cattle for bioreactor system purpose. Further process of our research will transfer of transgenic embryos to recipients and production of hGCSF secreting cattle.
