When insulin solutions (100 U kg?1) at various pH values were placed in the rectum of rabbits, a large decrease in blood glucose concentration was observed except at the pH close to the iso-electric point of insulin. The effect of surface-active agents on the rectal absorption of insulin was examined by measuring the blood glucose concentration after the administration of 2 or 5 U kg?1. Non-ionic ether type, anionic, cationic and amphoteric surfactants as well as bile acids increased the absorption. The optimal effect with suppositories was reached with the addition of 1% polyoxyethylene (9) lauryl alcohol ether. Insulin suppositories containing agents enhancing rectal absorption were compared with the insulin for intravenous, intramuscular and subcutaneous injection. The changes of blood glucose and plasma immuno-reactive insulin concentration after rectal administration of insulin were similar to those after intravenous injection. 相似文献

In order to investigate the role of food antigen-specific T cells circulating in the blood of patients with food allergy, we compared T cell response to three casein components (αs-, β- and, K-casein) with specificities of IgG and IgE binding to the casein components in four milk-allergic patients (P1-4) with atopic dermatitis. In all patients, the binding activities of IgG antibodies to αs-casein were most dominant, followed by those to β- and to K-casein. The major component of casein bound by IgE antibodies was αs-casein in P1 and P3, K-casein in P2, and αs-casein as well as K-casein in P4; the order of casein components bound by IgE antibodies was different from that by IgG antibodies. Proliferative responses of peripheral blood mononuclear cells (PBMC) to casein components were so low that the dominance of casein recognition could not be clearly demonstrated. However, short-term T cell lines that specifically respond to casein were successfully established from PBMC of the four patients and the proliferative responses of the T cell lines to the three components of casein were in accord with the IgE antibody specificity to casein components but not with that of IgG antibody specificity. When taken together, these results indicate that casein-specific T cells circulating in the blood are involved in or reflect an allergic reaction against casein. 相似文献

Estrogen recepter (ER) assays in multiple sites within largetumors of breast cancer were performed by sucrose gradient centrifugation,and the ER status and the number of binding sites were determinedand compared with the cell-strornal ratio. In eight of 21 cases,inter-site variation in the number of binding sites within atumor was shown. Of these, six cases having relatively low ERlevels even showed differences in their ER status. These resultssuggest it is possible for a single assay in a small part ofa large tumor to be misleading concerning the ER status. ERassays of a mixture of cytosols from multiple sites of the tumorand of the tissue slice at the largest cross section showedthat the ER value of the tissue slice was the same as the averagewithin the tumor. In comparing the ER status and the cell-stromalratio, some correlation between the two factors was demonstrated. 相似文献

Hypoparathyroidism is a clinical disorder characterized by hypocalcemia and hyperphosphatemia in the absence of renal failure and hypomagnesemia. The causes of hypoparathyroidism can be classified as two groups: (i) insufficient parathyroid hormone (PTH) secretion in relation to the serum calcium level (hypoparathyroidism); and (ii) impaired PTH action (pseudohypoparathyroidism). The main emphasis in this report is to distinguish subgroups based on the etiology and pathophysiology of the various aspects of the disease. 相似文献

Abstract Neurosarcoidosis with recurrent stroke-like episodes has been reported only rarely in the literature. We repeatedly measured brain magnetic resonance images (MRI), SPECT, and electroencephalograms (EEG) in a 32-year-old male patient with this condition. In the acute stage of the episodes, he showed semi-coma followed by severe dysphasia; left-frontal EEG delta wave activities and left-sided hyperperfusion SPECT were noted. Gadolinium diethylenetriaminepentaacetic acid (Gd-DTPA) MRI findings were aggravated diffusely in the convalescent stage of the disease rather than in the acute stage. The EEG and SPECT findings were clearly reflective of an early stage of acute encephalomeningitis caused by the neurosarcoidosis, and thus are more useful than MRI for evaluation of the acute inflammatory process in this condition. 相似文献
