以麝香百合渣、麝香百合膳食纤维和卷丹渣为原料进行实验，并通过建立便秘模型，了解百合膳食纤维对小白鼠润肠通便功能的影响，实验结果证明，百合膳食纤维极显著缩短了小鼠的首次排便时间（p<0.Ol），麝香百合渣、卷丹渣能够增加小鼠的排便质量，其有效剂量为7.8g/kg，当剂量达到15.6g/kg时，所有实验组均能极恩著增加排便质量，中浓度卷丹渣能显著提高粪便含水率（p<0.05），高浓度百合膳食纤维能够极显著增加小鼠粪便含水率(p<0.01)。中、高浓度的百合膳食纤维能极显著增加小肠推进率(p<0.01)。由此说明，百合膳食纤维能改善便秘模型小鼠的通便功能，并且以高浓度百合膳食纤维的效果最佳。

综述了渍水土壤还原过程中微生物代谢、化学变化、土壤结构和土壤胶体的稳定性的相关研究，在还原过程中，随着好氧细菌、兼性厌氧细菌、硫酸还原菌和甲烷菌的活动，相继形成氨、硝酸根离子、亚铁离子、硫化物、气体物质及有机酸，在渍水初期，水溶性阳离子浓度的增加导致土壤悬浊液凝集，在渍水后期，亚铁沉淀的形成致使二价水溶性阳离子浓度降低，使得土壤胶粒悬浊液分散，在还原条件下，土壤胶体稳定性的变化过程是一个动电机理.

Flocculation and dispersion of colloidal particles of nine inorganic paddy soils were studied mainly based on turbidity measurements of the suspensions of soils which were prev:iously incubated at 28℃ under in, vitro waterlogged conditions. After l-week of incubation, the turbidity of the soils except for l) two soils containing larger amounts of sodium salts and 2) one soil containing larger amounts of Fe and Al oxides, significantly decreased, and colloidal particles flocculated with l) a decrease in soil Eh and 2) an increase in electric conductiv-ity (EC). During the 3-t0 4-week period of waterlogging, the turbidity of the three soils significantly increased with the l) decrease in EC and 2) increase in pH of the soils although the Eh remained low. Infrared (IR) absorption analysis showed that the suspended colloidal particles consisted of layer sili-cates from respective soil clays. Oxidation of suspensions of waterlogged soils by air-bubbling led to an increase in turbidity with the l) increase in Eh, and 2) decrease in pH, EC, and water-soluble Fe2+ concentration. It was suggested that the stability of the soil colloidal suspensions was affected by soil reduction with alterations in ionic species and their concentrations at clay surfaces and in soil solutions.

The electrokinetic behavior of colloidal particles in three waterlogged soils at 38℃ was investigated with reference to the stability changes of soil colloidal suspensions under reductive conditions. The dispersed clay particles of the three sons exhibited a negative zeta (ζ) potential. The absolute value of the ζ-potential, |-ζ| of these soils in the earlier period of waterlogging decreased, which caused the flocculation of clay particles. The concentrations of divalent cations, i.e., Fe2+ and Ca2+ in the soil solutions were estimated to be higher than their critical flocculation concentrations (CFCs) on the basis of the observed CFCs of Fe2+ and Ca2+ for the clay suspension of halloysite as a reference. With the progression of the reduction process, clay particles of one soil still exhibited a low |-ζ| and fiocculated. The concentrations of Fe2+ and Ca2+ in the soil solutions were estimated to be higher than their CFCs, respectively. The clay particles of two sandy soils, however, showed an increase in |-ζ| due to the increase in pH and dispersed. The concentrations of Fe2+ and Ca2+ in the soil solutions were estimated to be lower than their CFCs, respectively. The stabil-ity changes of the soil colloidal suspensions by these divalent cations under sequential soil-reduction can be explained by the alteration of the Stern potential (-ψs), which determines the repulsion energy related to the potential energy of interaction'between two particles. The apparent decrease in the Ca2+ concentration of the soil solutions in the later period of waterlogging was explained largely by the re-adsorption of water-soluble Caz+ on the exchange sites of soil clays with the decrease in the Fe2+ concentration in the soil solution.
