The substrate level of the photosynthetic reductive pentosephosphate cycle in spinach leaves during SO2 fumigation wassurveyed. At the beginning of SO2 fumigation, fructose-1,6-bisphosphateincreased and fructose-6-phosphate decreased, while ribulose-1,5-bisphosphateremained unchanged and 3-phosphoglyceric acid rapidly decreased.These results suggested that the inhibition of photosynthesisin spinach leaves with SO2 might be due to inactivation of fructose-1,6-bisphosphatase.

Summary A new haptenic compound, a muramyl dipeptide (MDP) derivative (designated as L4-MDP-ONB) cross-reactive with Bacillus Calmette Guerin (BCG) was synthesized. The cross-reactivity of L4-MDP hapten to BCG was demonstrated from the following evidence; (a) lymph node cells from BCG-primed C3H/HeN mice exhibited appreciable L4-MDP-specific proliferative responses to the in vitro stimulation of L4-MDP-modified syngeneic cells (L4-MDP-self); (b) inoculation of L4-MDP-self into footpads of BCG-primed C3H/HeN mice elicited ample delayed type-hypersensitivity (DTH) responses in vivo as measured by footpad swelling; and (c) BCG-primed mice contained L4-MDP-reactive helper T cell activity which functions to augment the generation of effector T cell responses to cell surface antigens. This crossreactivity between L4-MDP hapten and BCG as measured by the helper T cell activity was applied to enhanced induction of tumor-specific immunity. When BCG-primed C3H/HeN mice were immunized with L4-MDP-modified syngeneic X5563 tumor cells, these mice could generate augmented tumor-specific in vivo protective (tumor neutralizing) immunity as well as in vitro cytotoxic T cell responses. These results indicate the effectiveness of L4-MDP hapten in augmenting tumor-specific immunity. The present approach is discussed in the context of potential advantages of this new hapten for its future application to clinical tumor systems. 相似文献

- 1. 1. The study aimed at knowing whether thermal sensation during afternoon cool exposure could be influenced by bright light (4000 lx) or dim light (200 lx) in the forenoon.
- 2. 2. The subjects felt cooler after exposure to dim light than to bright light.
- 3. 3. Melatonin in the urine was significantly higher in bright light than in dim light at 10:30 h and at noon.

The primary purpose of this study was to test our hypothesis that the behavior of self-selecting the preferred ambient illuminance might be determined by a load error between the core temperature and its set-point. Seven female volunteers were asked to choose the preferred ambient light intensity by adjusting a rheostat from the time when they rose spontaneously in the morning to the time when they felt sleepy and retired. Rectal temperature was measured every 10 min. Their preferred ambient light intensity increased quickly and then gradually after they rose and rose to approximately 2000 lx over 3 hrs. It decreased gradually and then quickly to the time when they retired. We discussed these findings in terms of a load error between the actual core temperature and its set-point. 相似文献
