The fluorescence anisotropy using steady-state fluorescence polarization method was measured for the solution of β-CD and cinchonine mixed and sonicated for 1h. The anisotropy values for the solution increased with the increase of the concentrations of β-CD, which implied the existence of some complexes of large size or nanotube structure. Many type of large size complexes formed between β-CD and Cin under high concentrations in gas phase were characterized by ESI-MS in moderate experiment conditions.

Small intestinal biopsies showed subepithelial collagen deposition with varying degrees of villous atrophy and varying numbers of intraepithelial lymphocytes. Four patients had previous biopsies showing enteropathic changes without collagen deposition. Seven cases were associated with collagenous colitis and 1 also had features of lymphocytic colitis. Three patients also had collagen deposition in gastric biopsies. One case was associated with lymphocytic gastritis. Celiac disease (CD, gluten-sensitive enteropathy) was documented in 4 patients. Five patients made a clinical improvement with combinations of a gluten-free diet and immunosuppressive therapy. Two patients died of complications of malnutrition and 1 of another illness. Clonal T-cell populations were identified in 5 of 6 cases tested. Four of these patients improved clinically after treatment but 1 has died. Collagenous sprue evolved on a background of CD in 4 cases. There was no history of CD in others and these cases may be the result of a biologic insult other than gluten sensitivity.
