Stability of fucoxanthin was assessed in dried Undaria pinnatifida (wakame). After 210 days storage of dried wakame in the dark at 50°C, the stability of fucoxanthin was higher than that of purified fucoxanthin incubated at both 20°C and 40°C. Furthermore, we analyzed the stability of fucoxanthin in scones containing 0.5 − 2 wt% commercial dried wakame powder. More than 85% of the fucoxanthin remained unchanged in the scones after heating the dough at 190°C for 30 min. Sensory analysis indicated that although the addition of wakame powder darkened the appearance and strengthened both the taste and smell of the scones, they remained acceptable. Furthermore, overall sensory scores showed that scones containing 0.5 wt% and 2 wt% wakame powder were more favorable than control scones.

The effects of single administration of Lactobacillus plantarum No. 14 (LP14) on human body temperature and factors related to sympathetic nerves were measured in a randomized, double-blind, cross-over study. LP14 significantly increased chest temperature (P < 0.05). The maximum difference in temperature between LP14 and placebo was 0.24 ± 0.24℃. Systolic blood pressure increased significantly, and arousal scores tended to increase in the LP14 group. The results of the Uchida-Kraepelin test indicated that LP14 elevated task performance. Our results demonstrated that LP14 induced thermogenesis in humans. We also examined the activity of the sympathetic nerves (SNA) innervating brown adipose tissue (BAT) in rats. The activity of BAT-SNA was significantly enhanced in the LP14 group. As LP14 changed factors associated with sympathetic nerves in humans and elevated sympathetic nerve activity in rats, sympathetic nerve activation appears to participate in thermogenesis elicited by LP14.

To investigate the long-term effect of feeding royal jelly (RJ) on the testicular function, 32-week old male golden hamsters were fed diet containing RJ at doses of 0 μg/g diet (control), 50 μg/g diet or 500 μg/g diet for 12 weeks. At the end of the experiment, the hamsters were assessed for testicular function in terms of the amounts of intra-testicular free testosterone (TS) and histopathological changes. RJ diet groups showed higher TS levels and more intensive spermatogenesis than the control group in a dose-dependent manner. The intensity of spermatogenesis and TS levels in the 500 μg of RJ/g diet group showed significant differences of p < 0.01 and p < 0.05, respectively, when compared with those in the control group. These results indicate that the long-term feeding of RJ inhibits the age-associated decline in the testicular function of male hamsters.
