The double differential thick target neutron yields from 9 MeV deuteron incidence were measured at the Kyushu University Tandem Accelerator Laboratory. A copper and a titanium foils which are thick enough for a deuteron to stop in the foils were placed at the center of a vacuum chamber. An NE213 liquid organic scintillator was employed to detect neutrons emitted from targets and placed at 9 directions from 0˚ to 140˚. To consider the contribution of scattered neutrons from the floor, we also measured neutron yields with an iron shadow bar located in front of the scintillator. Because incident deuteron beam was not pulsed and the Time-of-Flight method was not applied, the energy spectrum was derived from unfolding the light output spectrum using the FORIST code. The detection efficiency was calculated with the SCINFUL-QMD code. The experimental results were compared with the calculation data of the TALYS code, and it turned out that the calculation data does not reproduce the experimental ones satisfactorily.

Previously, we reported that a diet including sesame meal (SM) increased plasma total and high-density lipoprotein (HDL)-cholesterol concentrations in goats. In the present study, the components in the sesame meal that can increase plasma total and HDL-cholesterol concentrations have been examined. In experiment 1, we gave goats defatted sesame meal diet (DSM) to investigate the influence of ether extract fraction remained in sesame meal. Corn gluten meal diet (CGM) was also fed to goats as a high-protein diet to examine the influence of high dietary protein level caused by usage of sesame meal. Plasma total and HDL-cholesterol concentrations of goats fed DSM and CGM did not change during experimental periods though they were elevated by feeding SM. In experiment 2, the influence of sesame oil and corn oil added in diets on plasma total and HDL-cholesterol concentrations in goats was investigated. Plasma total and HDL-cholesterol concentrations were increased by feeding both corn oil diet and sesame oil diet. In conclusion, the increase in plasma HDL-cholesterol concentration by feeding sesame meal was resulted by the effect of ether extract fraction including sesame oil or some lipid-soluble components remained in sesame meal.

Influence of dietary sesame meal on plasma glucose, non-esterified fatty acid (NEFA), triglyceride, total cholesterol, high-density lipoprotein (HDL)-cholesterol and urea concentrations in goats was examined. Goats were fed a control diet (50% timothy hay and 50% concentrates) (CD) or a sesame meal diet (50% timothy hay, 25% concentrates and 25% sesame meal) (SMD) during 12 days. Blood samples were taken after overnight fasting and afternoon every day. Body weight was not changed by feeding either CD or SMD. The concentrations of plasma triglyceride and urea were higher (p<0.05) in goats fed SMD than those fed CD. Plasma NEFA concentration was higher in plasma samples after overnight fasting. Plasma glucose concentration in plasma samples collected afternoon was higher than those after overnight fasting. Plasma total cholesterol concentration was significantly increased by feeding SMD but not by feeding CD, which was due to the remarkable increase of plasma HDL-cholesterol concentration. In conclusion, dietary sesame meal brought about an increase in plasma total cholesterol concentration accompanied with an increment in plasma HDL-cholesterol consentration in goats.
