Purpose: The aim of this study is to investigate the criteria of biochemical recurrence (BCR) and follow-up periods and methods with and without blood and imaging test of urologic oncology before established guidelines of prostate cancer in Korea. Materials and Methods: In December 2015, we sent the questionnaire to urologic oncologist in academic hospital and received the answer from 108 urologic oncologist (50%). Also, we analyzed the data of 1,141 patients underwent radical prostatectomy in 2005 from Korean Medical Insurance. Results: In follow-up, 72 physicians (66.7%) performed blood test every 3 months, 51 physicians (47.2%) performed imaging study in case of BCR. Bone scan was the most common imaging study in the follow-up (74 physicians, 68.5%). But, bone scan was only performed in case of BCR (43 physicians, 39.8%). The criteria of BCR was PSA 0.2 ng/mL (75 physician, 69.4%), 76 physicians (70.4%) was performed different follow-up according to risk of patients. In Korean Medical Insurance data analysis, PSA were performed average 2 times every year and magnetic resonance imaging, computed tomography, Bone scan were performed average 0.1, 0.2, 0.1 times every year, respectively. Conclusions: The criteria of BCR and the follow-up of prostate cancer patients in Korea were similar Korean prostate cancer guidelines. Blood and imaging test might be increased compared to 10 years ago, it is necessary to compare the Korean Medical Insurance data between 10 years ago and present.

To investigate the application of biochemical markers' and small-sample methods using whole-wheat flours for screening in early generation in Korean wheat breeding system, 74 Korean wheats, including cultivars, local breeding lines and experimental lines, were analyzed. Seed storage protein and amylose contents of grains were evaluated. Biochemical makers, including granule bound starch synthase (GBSS), high molecular weigh glutenin subunits (HMW-GS) and friabilin were also evaluated by using one-dimensional sodium dodecyl sulfate-polyacryla-mide gel electrophoresis with a single kernel. The small­sample methods, including modified SDS-sedimentation test (MST), micro-alkaline water retention capacity (AWRC) and whole-wheat flour swelling volume (WSV) were also tested in this study. Protein content, MST and AWRC was $11.0 - 15.8\%$, 2.7 - 26.2 ml and $71.9 - 109.7\%$, respectively. Apparent and total amylose content and WSV was $20.6 - 25.0\%$, $26.1 - 32.4\%$ and 9.0 - 16.9 ml, respectively. There were highly significant correlations between MST and AWRC (r=0.592, P<0.001), but Korean wheats showed no significant difference in protein content, amylose content and small-sample methods. In the biochemical markers, Korean wheats contained all three GBSS encoded by Wx loci, except for Suwon 252. Korean wheats showed the high frequency ($58.1\%$) of 1Dx2.2 + 1Dy12 subunits of HMW-GS. Friabilin band was present in 46 lines ($62.2\%$) and absent in 28 lines ($37.8\%$). Friabilin-absence lines showed the higher MST (14.9 ml) and AWRC ($92.1\%$) value than friabilin-presence lines (8.5 ml and $82.4\%$, respectively).

The study was carried out on the biochemical characters of Cd-BP(I) after isolation and purification of the protein from the liver of rat injected intraperitoneally with Cd. A c ontinued study has been doing whether Cd-BP(I) could be induced by Cd or by other metals such as Zn and Cu. Antisera were made against the Cd-BP(I) from NewZealand white rabbits. Carried out were ${\gamma}$-globulin purification, then Ouchterlony test adn gel immunodiffusion test. Cd-BP(I) was also found in normal tissues of rat. It was induced up to a considerable level by Cd, whose induced level was higher than that of Cu or Zn treatment. The level of induction by Cu or Zn pretreatment plus Cd treatment was lower than that by simple treatment of Cu or Zn. Such a result was presumably related to the Cd toxicity.

1) Puerariae Radix butanol ext. (100, 200, 400mg/kg, p.o. single treatment) alone partly showed blood pressure decreasing effect in SHRs and increasing effect of urinary volume in normal rats. 2) Cadmium nitrate (10mg/kg, s.c. single treatment) induced toxicity such as body weight decreasing effect, antidiuretic effect and muscle relaxant effect such as pull-up test, traction test and rota rod test in rats. However, Puerariae Radix butanol ext. (100, 200, 400mg/kg, p.o. single treatment) showed antidotal effects on the above and also in acute toxicity test when coadministered with both of them. 3) Cadmium nitrate (1mg/kg, s.c. 7 days consecutive treatment) did not showed toxicity in body weight change, blood pressure, change, serum biochemical parameters in rats. Puerariae Radix butanol ext. (100, 200, 400mg/kg, p.o. 7 days consecutive treatment) did not also showed any antidotal effects when coadministered with both of them for 7 days.

Objectives : The purpose of this study is to investigate Acute and Subacute Toxicity, and Anti-cancer Effect of H Herbal-acupuncture on mice and rats. Methods : Balb/c mice were injected intraperitoneally with H Herbal-acupuncture for $LD_{50}$ and acute toxicity test. Sprague-Dawley rats were experimented in the same way for subacute toxicity test. H Herbal-acupuncture was injected into abdomen of mice having S-180 cancer cell line. Result : 1. During the test, $LD_{50}$ could not be counted since there was no expired subjects. 2. In an acute toxicity test, the loss of motility and reflex action was observed, but weight increased in the treatment group, compared with those in the normal group (P<0.05). 3. In an acute toxicity test of serum biochemical values of mice, glucose increased in the treatment group II while total cholesterol was increased in the all treatment groups (P<0.05). 4. In a subacute toxicity test, a little loss of motility and reflex action was observed in the treatment group. Weight of mice in the treatment group decreased on the 28th day. 5. In a subacute toxicity test, liver weight was decreased but lung weight of mice increased in the all treatment groups (P<0.05). 6. As a result of measuring Complete Blood Count test (CBC) of rat, HCT was decreased in treatments even though it was not significant, compared with the normal group (P<0.05). 7. In a serum biochemical value test of subacute toxicity, total protein and albumin decreased in the all treatment groups. Creatinine, glucose, GOT increased in the treatment group I compared with the control group. Alkaline phos-phatase decreased in treatment II group, compared with the control group (P<0.05). 8. Median survival time that was measured in the rats treated with sarcoma-180 cancer cell Median decreased in the treatment group, compared with the control group (P<0.05). 9. Natural killer cell activity showed significant reduction at 100:1 and 10:1 E/T ratio while it increased at 50:1 E/T ratio. It is inferred that there was an error in the experiment (P<0.05). 10. In an interleukin-2 productivity test, even though it decreased in lung cancer, and increased in abdomen cancer, but it was only a small difference (P<0.005). 11. After injecting B16F10 cell into a capillary vessel of C57BL/6 mice and generating metastasized lung cancer, the lung was examined with the naked eye. It was not possible to see metastasized cancer in the all groups on the seventh day but the cancer was viewed on the fourteenth day. The number and volume of metastasized cancer in the treatment group enlarged in the treatment group, compared with the control group. Conclusion : According to the results, H herbal-acupuncture took no effects in cancer.

In the present work, a basic study on the in-situ biogenic methane generation from low grade coal bed was conducted. Lignite from Indonesia was used as a sample feedstock. A series of BMP (Biochemical Methane Potential) tests were carried out under the different experimental conditions. Although nutrients and anaerobic digester sludge were added to the coal, the produced amount of methane was limited. Both temperature control and particle size reduction showed little effect on the increase of methane potential. When rice straw was added to lignite as an external carbon source, methane yield of 94.4~110.4 mL/g VS was obtained after 60 days of BMP test. The calorific value of lignite after BMP test decreased (4.5~12.1 %) as increasing the content of rice straw (12.5~50 wt % of lignite), implying that anaerobic digestion of rice straw led to partial degradation of lignite. Therefore, rice straw could be used as an external carbon source for the start-up of in-situ biogas generation from low grade coal bed.

Purpose: Noninvasive prenatal test (NIPT) by massively parallel sequencing (MPS) of cell-free fetal DNA in maternal plasma marks a significant advancement in prenatal screening, minimizing the need for invasive testing of fetal chromosomal aneuploidies. Here, we report the initial clinical performance of NIPT in Korean pregnant women. Materials and Methods: MPS-based NIPT was performed on 910 cases; 5 mL blood samples were collected and sequenced in the Shenzhen BGI Genomic Laboratory to identify aneuploidies. The risk of fetal aneuploidy was determined by L-score and t-score, and classified as high or low. The NIPT results were validated by karyotyping for the high-risk cases and neonatal follow-up for low-risk cases. Results: NIPT was mainly requested for two clinical indications: abnormal biochemical serum-screening result (54.3%) and advanced maternal age (31.4%). Among 494 cases with abnormal biochemical serum-screening results, NIPT detected only 9 (1.8%) high-risk cases. Sixteen cases (1.8%) of 910 had a high risk for aneuploidy: 8 for trisomy 21, 2 for trisomy 18, 1 for trisomy 13, and 5 for sex chromosome abnormalities. Amniocentesis was performed for 7 of these cases (43.8%). In the karyotyping and neonatal data, no false positive or negative results were observed in our study. Conclusion: MPS-based NIPT detects fetal chromosomal aneuploidies with high accuracy. Introduction of NIPT as into clinical settings could prevent about 98% of unnecessary invasive diagnostic procedures.
