Physiological effects of yeast hydrolysate SCP-20

When the yeast hydrolysate SCP-20 from Saccharomyces cerevisiae ingested to the rat to identify the effect on anti-stress, SCP-20 have an potent effect on the weight of adrenal, spleen, kidney and thyroid, and the glutamic pyruvic transaminase (GOT), glutamic oxaloacetic transaminse (GPT) and lactic dehydrogenase (LDH) activity recovered as much as the non-stress level. In addition, the swimming time was significantly increased in the group to administer SCP-20. It is assumed that anti-fatigue effect might relate to the resistance effect on the stress induced intensive exercise. SCP-20 stimulated not only the activation of macrophage (1.9-fold of saline control) but also IL-6 production (1.9-fold) at 2.0 g/kg/day. By the culture supernatant of Peyers patch cells from C3H/HeJ mice fed SCP-20 at 2.0 g/kg/day for 7 days, the bone marrow cells significantly proliferated as 2.1 fold to compare with those of mice received only saline (control). In addition, the contents of IL-6 in the culture supernatant of Peyers patch cells from mice fed SCP 20 at 2.0 g/kg per day were increased in the comparison with those from control (2.3-fold).

Physiological Characteristics of Resistant Starch (HI-MAIZE DIET) Fortified with Other Dietary Fiber Components

This study was performed to investigate the influences of resistant starch (HM: HI-MAIZE) and HM-D (HI-MAIZE DIET) fortified with D-factor (consisted of Psyliium husk, polydextrose and hydrocitric acid) on the glucose and bile acid absorption and production of short chain fatty acids (SCFA). HM-D absorbed more glucose and bile acid than did HM. The glucose transport of HM and HM-D against dialysis membrane showed 77% and 68% for 4h, respectively. After 24h, bile acid transport of HM and HM -D showed 65% and 62.3%, respectively. The HM and HM-D produced 217.8 mM and 264.0mM of SCFA, respectively. The production of butyric acid in HM-D (32.7mM) showed higher than that of HM (26.9mM). The addition of D-factor to HM increased the physiological function of dietary fiber through the glucose and bile acid absorption and production of SCFA.
