This study was conducted to investigate the effect of the ingestion of rice and hamburger meals upon the plasma gastrin concentration in normal human subjects in Korea. Eight normal human subjects including male and female with the mean age of 28 years (range: 20-40 years) were studied. After an overnight(about 15 hrs) fast each subject ingested a rice meal and a hamburger meal on different days. The rice meal consisted of 250 g boiled rice, 50 g vegetables and 200 ml barley tea, corresponding to 6.8 g protein, 0.5 g fat and 81g carbohydrate and the hamburger meal consisted of 200 g hamburger, 50 g vegetables ana 200 ml milk, corresponding to 43 g protein, 43 g fat and 9 g carbohydrate. The venous blood samples were drawn before and after the ingestion of the test meal at the following times: -30, 0, 15, 30, 45, 60, 90, and 120 min, for measurement of gastrin by radioimmunoassay. The following results were obtained : 1) Plasma gastrin concentration in response to the ingestion of the rice or the hamburger meal increased significantly compared with the concentration in fasting state. 2) The increase of the plasma gastrin concentration after the hamburger meal was significantly higher than that after the rice meal. 3) There was a significant linear correlation between the postprandial peak plasma gastrin concentration after the rice meal and the concentration after the hamburger meal in each subject. It is inferred from the above results that a carbohydrate meal as well as a protein meal has a stimulatory effect on gastrin release in normal human subjects.

The purpose of this study was to compare cerebral blood flow between hyperlipidemic patient group and normal healthy aldult group using transcranial doppler ultrasonography(TCD). I investigated cerebral blood flow of 63 hyperlipidemic patients and 42 healthy adults. To evaluate the cerebral blood flow, I measured the systolic peak velocity(Vs) and mean flow velocity(Vm) of the milddle cerebral artery(MCA), anterior cerebral artery(ACA), posterior cerebral artery(PCA), basilar artery(BA), internal carotid artery(ICA) in the two groups using TCD. In normal healthy adults, subjects showed a decerease in Vs and Vm with advancing in age. There was a significant difference in the Vm of ICA. There was no significant differences in the Vm of ACA and ICA. In normal healthy adults, females showed high velocities of all examined vessel. There was a significant difference in the Vs of ICA. There was a significant differences in the Vm of MCA and ICA. Normal healthy adults higher than hyperlipidemic patients in the Vs of MCA, ACA, PCA. There was no significant difference in the Vs of all exmined vessels. Hyperlipidemic patientsincrease higher than normal healthy adults in the Vm of ACA. There was a significant difference in the Vs of BA. In the patients aged under 50's, normal healthy adults higher than hyperlipidemic patients in the Vs and Vm except BA. But there was no significant difference in all exmined vessels. In the patients aged over 50's, hyperlipidemic patients higher than normal healthy adults in all examined vessel expect PCA. There was a significant difference in the Vs of BA and ICA. And hyperlipidemic patients higher than that normal healthy adults in all exmined vessels. There was a significant difference in BA and ICA. In this study, visible differences in blood flow between hyperlipidemic patient group and normal healthy aldult group were shown. However, these results do not come up to the previous values that were reported and known worldwide.

To examine the difference of health-related quality of life (QoL) of obese patients between before and after treatment of Korean traditional medicine. This study was assessed in 18 obese-women (age 29.72${\pm}$7.38) treated by acupuncture and herbal medicine using SF-36 quality of life questionnaire between January and July 2006, a 36 item instrument yielding 8 dimensions (Social functioning, Role limitation-Physical, Role limitation-Emotion, Mental health, Vitality, Bodily pain, and General health) and a total score. Their weight was measured by Inbody 3.0 (Biospace co. Korea). QoL and body composition was assessed twice at baseline (B) and 4 weeks after treatment. Auricular acupuncture and electrical needle stimulation to abdomen, thigh, and arm fat was used twice a week and complex herb formula was prescribed according to their constitution and symptoms for 4 weeks. Herb medication was taken 2 times a day. Respective variables were analyzed with Wilcoxon signed ranks test and the level set for statistical significance was p <0.05. The mean of the body weight (P=0.000;B64,68${\pm}$6.86, 4 WKs 60.47${\pm}$5.69), fat percentage (P=0.000;B33.14${\pm}$4.86, 4 WKs 30.16${\pm}$5.34), body mass index (P=0.000;B25.18${\pm}$2.44, 4 WKs 23.46${\pm}$2.09) and fat weight (P=0.000;B21.66${\pm}$5.06, 4 WKs 18.41${\pm}$4.57) of some obese patients decreased significantly between before and after treatment for 4 weeks. Physical functioning (P=0.48;B27.06${\pm}$3.17, 4 WKs 28.00${\pm}$1.71), Mental health (P=0.01 ;B18.83${\pm}$5.25, 4 WKs 22.00${\pm}$3.73), Vitality (P=0.028;B13.89${\pm}$3.03, 4 WKs 15.44${\pm}$2.53), Bodily pain (P=.0014;B8.84${\pm}$1.75, 4 WKs 10.15${\pm}$1.78), and the total scores (P=0.001;B104.99${\pm}$12.60, 4 WKs 114.58${\pm}$11.11) of SF-36 were increased significantly after treatments. These data show some differences in QoL and BMI between before and after treatment on obesity and suggest that the treatment with acupuncture and herbal medicine have a positive impact on several domains of QoL of some obese patients. Further randomized clinical trials (RCTs) including follow-up are needed to examine whether acupuncture and herb medicine have a positive effect on QoL of treatment group compared with control group.

This study was carried out to investigate the effects of stem cutting ages and harvest time on the growth and yield of potato 'Dejima' in aeroponics. The stem cuttings were produced from in vitro plantlets and transplanted into an aeroponic system with 20, 30, 40 and 50 day-old stem cuttings (DOS). Tubers were harvested 60, 70, 80 and 90 days after transplanting (DAT) and sorted into following categories: $1{\sim}5$, $5{\sim}10$, $10{\sim}20$, $20{\sim}30$, $30{\sim}40$ and over 40 g. Plant height from the 40 DOS was the highest during the growing periods but no significant difference was observed on 75 DAT. The tuber weight increased until 90 DAT with the greatest weight of tubers in the 20 and 40 DOS. However, there was no significant difference among 20, 30 and 40 DOS in the number and weight of tubers. Harvesting at 80 and 90 DAT increased the number of tubers over 5 g, which are usually considered as appropriate for direct field planting.

Intramuscular fat content(lMF) is considered as one of major economic traits in the pig breeding and industry. In general, high IMF results in better meat quality. Several approaches to detect quantitative trait 10ci( QTL) for IMF indicated a strong possibility of the existence of a QTL related to IMF between the microsatellite marker SW71 and SW1881 on SSC6q. Porcine FABP3 has been considered as a candidate gene affecting IMF due to its physiological roles and position on the pig genome. Two novel mutations, g.-114T> C and g.-158T>G were detected by duplicate sequencing of the porcine FABP3 promoter region. These two mutations were identified as absolute linkage disequilibrium. The g.-158T> G mutation was used for investigating relationships with growth and fat deposition traits. The GG genotype of the g.-158T> G polymorphism showed highly negative effects(P< 0.01) on body weights at 3 and 12 weeks of age, and a positive effect(P< 0.05) on IMF. However, backfat thickness(BF) and carcass fat(CF) content were not significantly associated with the genotype. The result indicates that the novel mutations, identified in this study, could be utilized as possible genetic markers to improve IMF, independent with BF.

Background: The purpose of this study is to analyze the effects of an abdominal obesity management program in middle-aged women in Korea. Methods: Examination of databases, including the Research Information Sharing Service, Database Periodical Information Academic, and Korean Studies Information, resulted in identification of 772 studies performed up to 2014, of which 43 satisfied the inclusion data. Data analysis was performed using R version 3.2 to calculate the effect sizes, explore possible causes of heterogeneity, and check for publication bias, using a funnel plot and its trim-and-fill analysis. Results: The mean effect size of the management program was small (g=0.22), along with the anthropometric index (g=0.18), metabolism index (g=0.21), fat-distribution (g=0.36), and inflammatory index (g=0.36). Moderator analysis was performed to determine heterogeneity, but no significant differences were found between the randomized controlled trial (RCT) group and non-RCT group. In addition, the length of the session was found to be statistically significant after performing a meta-regression. Finally, a funnel plot with a trim-and-fill analysis was produced to check for publication bias, but no significant bias was detected. Conclusion: Based on these findings, the abdominal obesity management program affects middle-aged women in Korea. Further research is needed to target other age groups with abdominal obesity.

The aim of this study was to achieve optimal portal phase while reducing contrast medium by applying weight-based dose protocol compared to standard fixed dose protocol to performing of pediatric abdominal CT examination. Discovery 750HD (General Electric Medical Systems, Milwaukee, USA) was used, and a total of 167 children consisting of 85 men and 82 women under the age of 18 were studied. The group in which the 300 mgI/ml(Xenetix, Guerbet, France) contrast medium was fixedly injected at twice body weight and the group injected with physiological saline while gradually decreasing the injection amount by 10% while applying the weight-based protocol were distinguished. Also, the CT number and SNR of abdominal organs were compared and evaluated while changing the scan delay time. Subjective image quality of enhancement and beam-hardening artifacts of around the heart was assessed with five-point criterion. The group adapted weight-based protocol with 20% reduction in contrast medium was most similar in contrast enhancement in the group with fixed injection at twice body weight. Furthermore, the group with a delay time of 20% had the highest contrast enhancement effect, and the difference in CT attenuation coefficient from the group scanned immediately after injection of the contrast media. Therefore, the appropriate delay time after injection of the contrast agent increased the contrast enhancement of the parenchymal organ. In addition, the weight-based injection protocol with normal saline reduced artifacts around the heart, and the effect of contrast enhancement could be maintained. In conclusion, it is possible to reduce dosage of contrast media through the application of weight-based injection protocols and appropriate latency, and to characterize optimal portal phase imaging on pediatric abdominal CT.

In order to reduce the social and economic costs due to the increase in dementia patients, which is a representative senile disease in an aging society, it will be important to prevent dementia and to detect and treat early in high-risk groups. This study reported the results of treatment for the elderly with high risk of dementia and depression who received Korean medicine (KM) treatment in 9 KM clinics. Medical charts were surveyed on 116 patients with high risk of dementia and depression who received KM treatment at 9 KM clinics in Gangseo-gu from September 1, 2020 to December 31, 2020. The majority of the patients were female(76.72%), the average age was 71.66±7.18 years old, and the average education level was 8.96±3.91 years. The average treatment period was 61.47±10.30 days, the average number of treatments was 15.38±1.06 times, and both acupuncture and herbal medicine were administered. After receiving KM treatment, cognitive assessment scores such as MMSE-DS and MoCA-K, depression-related GDSSF-K score, dementia knowledge, attitude, and preventive behavior, blood debilitation scale, and GQOL-D score were improved compared to before. There was no specific adverse reaction except that one patient with elevated AST and ALT levels was observed. This study showed improvement in cognitive function, depression, dementia-related scale, and quality of life in high-risk groups for dementia and depression over 60 years old who received KM treatment. More systematic and large-scale planned clinical studies will be needed.

Background: Excessive stress causes varied physiological and psychological disorders including male reproductive problems. Here, we attempted to investigate the protective effects of Korean Red Ginseng (Panax ginseng Meyer; KRG) against sub-acute immobilization stress-induced testicular damage in experimental rats. Methods: Male rats (age, 4 wk; weight, 60-70 g) were divided into four groups (n = 8 in each group): normal control group, immobilization control group, immobilization group treated with 100 mg/kg of KRG daily, and immobilization group treated with 200 mg/kg of KRG daily. Normal control and immobilization control groups received vehicle only. KRG (100 mg/kg and 200 mg/kg) was mixed in the standard diet powder and fed daily for 6 mo. Parameters such as organ weight, blood chemistry, sperm kinematic values, and expression levels of testicular-related molecules were measured using commercially available kits, Western blotting, and reverse transcription polymerase chain reaction. Results: Data revealed that KRG restored the altered testis and epididymis weight in immobilization stress-induced rats significantly (p < 0.05). Further, KRG ameliorated the altered blood chemistry and sperm kinematic values when compared with the immobilization control group and attenuated the altered expression levels of spermatogenesis-related proteins (nectin-2, cAMP responsive element binding protein 1, and inhibin-${\alpha}$), sex hormone receptors (androgen receptor, luteinizing hormone receptor, and follicle-stimulating hormone receptor), and antioxidant-related enzymes (glutathione S-transferase m5, peroxiredoxin-4, and glutathione peroxidase 4) significantly in the testes of immobilization stress-induced rats. Conclusion: KRG protected immobilization stress-induced testicular damage and fertility factors in rats, thereby indicating its potential in the treatment of stress-related male sterility.
