  • Background: Poor participation rates are often observed in colorectal cancer (CRC) screening programs utilising faecal occult blood tests. This may be from dislike of faecal sampling, or having benign bleeding conditions that can interfere with test results. These barriers may be circumvented by offering a blood-based DNA test for screening. The aim was to determine if program participation could be increased by offering a blood test following faecal immunochemical test (FIT) non-participation. Materials and Methods: People were invited into a CRC screening study through their General Practice and randomised into control or intervention (n=600/group). Both groups were mailed a FIT (matching conventional screening programs). Participation was defined as FIT completion within 12wk. Intervention group non-participants were offered a screening blood test (methylated BCAT1/IKZF1). Overall participation was compared between the groups. Results: After 12wk, FIT participation was 82% and 81% in the control and intervention groups. In the intervention 96 FIT nonparticipants were offered the blood test - 22 completed this test and 19 completed the FIT instead. Total screening in the intervention group was greater than the control (88% vs 82%, p<0.01). Of 12 invitees who indicated that FIT was inappropriate for them (mainly due to bleeding conditions), 10 completed the blood test (83%). Conclusions: Offering a blood test to FIT non-participants increased overall screening participation compared to a conventional FIT program. Blood test participation was particularly high in invitees who considered FIT to be inappropriate for them. A blood test may be a useful adjunct test within a FIT program.

  • Blood pressure is possible to diagnose a disease associated with blood pressure and judgment the current health of patients. Automatic blood pressure monitor capable of measuring a blood pressure easily in hospital and at home have become spread. In this study, we developed the blood pressure simulator (BPS) that can test the arm-type automatic blood pressure monitor that is commonly used in hospital. BPS is to produce a pressure similar to the pressure wave generated in the human blood using a servo disk motor. Then, using the silicon tube, it implements the situations such as human blood vessels, and to output the generated pressure waveform. Simply the BPS's phantom put on the cuff and it is able to simulate blood pressure. So anyone can quickly test the blood pressure monitor within one minute and it is possible to shorten the test time required for the automatic blood pressure monitor. In Performance test, the trends and the standard deviation of the values measured in the BPS is similar to the value of the measured pressure from people with normal blood pressure. Thus, the development BPS showed a possibility of taking into account the actual blood pressure measurement environment simulator.

  • Blood glucose information is important for self regulation in daily life, but the frequency of self test remains to be only 17%(9 tests/month) in Korea, mainly due to pain during blood sampling. The present study tried to validate the clinical efficacy of the forearm as an alternative sampling site with minimized pain. Capillary blood was sampled both on the index finger($G_F$) and the forearm($G_A$), immediately followed by glucose measurements in 531 subjects, 25 who visited the Health Enhancement Center of C University Hospital, then venous blood($G_V$) was sampled for glucose test. The blood glucose concentration measured on the forearm was closer to the venous glucose than on the finger. The mean difference between $G_V$and $G_F$ was only 10 mg/dL well within the internationally accepted error limit. Error grid analyses of $G_F-G_V$, $G_A-G_V$ and $G_A-G_F$ revealed that the number of data points in regions A and B took 100%, 99.8%, and 97.9%, respectively. These results demonstrate the forearm blood glucose test is not only accurate but also clinically valid. Therefore, the forearm blood glucose test can be a useful way of self managing the chronic diabetes with minimized sampling pain.

  • Purpose: $^{18}F$-FDG wholebody PET is to evaluate the tumor using glucose metabolism. The blood glucose level is important factor that affects on a result of examination. High glucose levels may interfere with tumor targeting due to competitive inhibition of FDG uptake by D-glucose. The blood glucose level measurement test strips used in the blood glucose measurement are classified into the capillary blood measurement test strips and general purpose measurement test strips that can measure the venous blood and capillary blood altogether depends on cases. The purpose of the study was to compare the blood glucose measurements between simultaneously obtained capillary and venous blood samples using the capillary blood measurement test strips, general purpose measurement test strips. Materials and Methods: A total of 46 subjects (32 males, 14 females) with a mean age of $57.3{\pm}12.3$ years were enrolled. The blood glucose estimation was performed with a Optium Xceed Glucometer (Abbott). Simultaneous capillary and venous blood samples were obtained from each subject. The blood glucose levels were measured using the capillary blood measurement test strips and general purpose measurement test strips. The capillary and venous measurements were compared using a pared t-test. Results: The mean capillary and venous glucose values using the general purpose measurement test strips were $95.2{\pm}12.4$ mg/dL and $104.1{\pm}14.4$ mg/dL, giving a statistically significant difference (p<0.001) between the mean values for the capillary and venous glucose samples (9.0 mg/dL; 95% confidence interval (CI) -11.2 to -6.7). The mean capillary and venous glucose values using the capillary blood measurement test strips were $91.5{\pm}13.6$ mg/dL and $108.6{\pm}16.2$ mg/dL, giving a statistically significant difference (p<0.001) between the mean values for the capillary and venous glucose samples (16.6 mg/dL; 95% CI -20.2 to -13.0). Conclusion: When measuring the blood glucose level before $^{18}F$-FDG PET examination, since the incorrect blood glucose level can be measured, it should note to measure the blood glucose level of the venous blood by the capillary blood measurement test strips. Therefore the measurement variation can be reduced to fulfill the standardized measurement procedure with the suitable measurement test strips, the preparation of the PET examination will be able to be clearly confirmed. In addition, the standardized procedure of the following measurement on the area which is same at all times the blood area in the blood glucose measurement among a capillary or a vein will be needed.

  • The aims of this study were to describe the effects of glucose-sweetened drinks on blood glucose, energy, and water intake at a meal 3 hours later. The effect of blood glucose on prandial energy intake and the relationship between water and energy intake during a meal were also determined. Twenty healthy normal-weight men were fed pizza test meals 3h after consuming four drinks of 0, 50g, 65g, and 75g glucose in random order, within-subjects design. Blood samples were measured at baseline and every 30 min after ingestion of drinks and 30min after the end of the test meal and the appetite was also assessed by visual analog test at the same interval. The results of this study showed that various glucose drinks altered blood glucose responses compared with that of water control(p<0.0001). Blood glucose areas under the curve(AUC) for glucose-sweetened drinks were significantly(p<0.05) higher than that for the control over 3 hours after a drink and 30 min after the test meal. Consumption of the glucose-sweetened drinks significantly increased(p<0.05) energy and water intake at a test meal compared with the water control, except the drink containing 75g glucose. For all drinks combined, the energy intake was negatively correlated with the blood glucose and positively correlated with the volume of water consumed at a test meal at 3 hours later.

  • Objectives: The purpose of this study is to find out the characteristics of dysmenorrhea patients with the Inbody test results by Sasang constitutions. Methods: The data from the 541 participants were collected using a structured measurement of menstrual pain. Based on the survey responses, we had 329 women with dysmenorrhea as the test group and 212 women without dysmenorrhea as the control group. The clinical trials subjects were asked to respond to another questionnaire for identifying their constitutional types and undergo Inbody test. Results: The result of a comparison of the test and control groups showed that the DSOM test showed that the scores of blood deficiency, qi stagnation, blood stasis and phlegm were significantly higher in dysmenorrhea. The result of the taeumin's test groups showed that the DSOM test showed that the scores of heat were significantly higher. For the Sasang constitution, there is a difference on the cause of the outbreak. Taeumin from blood deficiency, blood stasis, dampness, heart, kidney, phlegm and lung is associated with dysmenorrhea. Soeumin from blood deficiency, qi stagnation, blood stasis, liver, heart, spleen and phlegm is associated with dysmenorrhea. The ratio of overweight of taeumin was low in blood deficiency and yin deficiency. The ratio of lowweight of soeumin was high in heat. Conclusions: The DSOM test showed that the scores of blood deficiency, qi stagnation, blood stasis and phlegm were significantly higher in dysmenorrhea.

  • Objectives: This study investigated the effect of SM-2015 on blood alcohol clearance and hangover. We undertook this study to test whether SM-2015 is effective in decreasing blood alcohol concentration and preventing the symptoms of alcohol-induced hangover. Methods: Twenty healthy volunteers participated in this randomized crossover study. All participants were classified between an SM-2015 intake group (test group) and a non-intake group (control group). The primary outcome measure was the difference in blood alcohol concentration and hangover severity scores between the test and control groups. The secondary outcome measure was the difference in a liver function test (LFT) between the test and control groups. Results: After alcohol exposure, the sensitivity scores of blood alcohol concentration and hangover symptoms (sleepiness, dizziness, nausea, weakness, stomach pain, diarrhea, and concentration disorder) were significantly decreased in the SM-2015 intake group compared with the non-intake group. There were no differences in the LFT results between the SM-2015 intake group and the non-intake group. Conclusions: SM-2015 is effective in decreasing blood alcohol concentration and preventing the symptoms of alcohol-induced hangover. Larger studies are required to confirm these findings.

  • A randomized double-blind placebo-controlled study was conducted on 63 subjects to determine the antihypertensive effect of a vegetable drink in which sardine protein hydrolysates containing a dipeptide, Valyl-Tyrosine (VY), were incorporated. The subjects, consisting of people with mild hypertension, high-normal blood pressure and normal blood pressure, were randomly divided into test (male/female=25.6, average age 50.1${\pm}$10.4 years old) and control groups (26/6, 49.0${\pm}$5.0). Each subjects in the test group was given 195g of the vegetable drink containing 0.5g of sardine peptides (sardine protein hydrolysates) with 0.4 mg of VY (test drink) once a day for 13 weeks in a row, and subjects in the control group were given the same amount of the vegetable drink without sardine peptides (control drink) in the same manner. In the test group, 40 subjects with mild hypertension of high-normal blood pressure (130 mmHg${\leq}$systolic blood pressure (SBP)<160 mmHg and/or 80 mmHg${\leq}$diastolic blood the start of the test to 134.4${\pm}$11.1 mmHg during the first week of the test period, after which similar values were seen throughout the test period (13 weeks). Compared to the control group, the difference in SBP from vaseline was statistically significant in the test group throughout the intake period. DBP also decreased significantly from 88.0${\pm}$7.9 mmHg at baseline to 83.5${\pm}$8.6 mmHg after 13 weeks. In the control group, SBP and DBP were 140.8${\pm}$8.4 mmHg and 90.5${\pm}$6.6 mmHg respectively at the start of the test, and neither decreased during the test period. In subjects with normal blood pressure, neither those in the test group nor those in the control group showed a significant change in SBP and DBP during the test period. An excessive ingestion test was performed on 25 subjects with hypertension, mild hypertension, high-normal blood pressure, and normal blood pressure by giving 585g (3 times the recommended amount of intake) of the test drink for 14 days in a row. As a result, a significant decrease of blood pressure was observed in the hypertension, mild hypertension and high-normal blood pressure groups, but no excessive decline in blood pressure or any side-effects were associated with any subjects during the test period. In the groups with normal blood pressure, the excessive ingestion of the test drink did not affect blood pressure. In these two studies, physical check-ups and biochemical analyses of blood and urine were also conducted in all subjects, and no abnormalities were observed. These results suggest that the test drink containing sardine protein hydrolysates exhibited the antihypertensive effect in only the subjects with mild hypertension or high-normal blood pressure. No adverse effects were observed in either hypertensive of normotensive subjects.
