Summary Acid GAG were isolated from hepatic tissue from 3 patients with Hurler syndrome and 3 normal controls. Gross elevations in the uronic acid and hexosamine contents were found in Hurler livers compared with the normal ones. The total GAG concentration was significantly increased (about 25fold) in Hurler patients.This work was partially supported by research grants from the Conicet, Argentina. 相似文献

Summary The composition of urinary acidic glycosaminoglycans (AGAG) in 4 patients with Werner's syndrome was determined by an enzymatic assay system using chondroitinases and hyaluronidase. In Werner's syndrome, the amount of hyaluronic acid and heparan sulfates in the total AGAG increases. A compositional change in the chondroitin sulfate isomers occurs. The change of urinary AGAG in Werner's syndrome appears to reflect age-related changes.The study was supported, in part, by Grants-in-Aid for Scientific Research from the Ministry of Education, Science and Culture of Japan, the Life Science of the Institute of Physical and Chemical Research and the Adult Disease Clinic Memorial Foundation, Tokyo. Thanks are due to Dr Y. Yamada and Dr R. Abe for collecting specimens, and Miss R. Abe and Miss R. Yamaguchi for technical assistance. 相似文献

Resumen Se estudiaron los glucosaminoglucanos del líquido sinovial de la rodilla de pacientes con artritis reumatoidea clásica. El nivel de glucosaminoglucanos totales desciende en la artritis un 55% comparado con los controles. Esto es debido principalmente a la disminución del ácido hialurónico (59%). Se confirmó la presencia de pequeñas cantidades de controidin-4-sulfato y se detectaron trazas de una sustancia similar al condroitin-6-sulfato.

Summary Incorporation of [35]S-sulfate into hepatic glycosaminoglycans (GAGs) is affected by intravenous administration of endotoxin. There are significant increases in total labeled glycosaminoglycans and in the percentage of labeled dermatan sulfate 72 h post-endotoxin. 相似文献

Resumen Este estudio demuestra que en piel de ratas atiroideas, en comparación con las normales, el ácido hialurónico aumenta un 20% mientras que el dermatán sulfato disminuye un 28%, no encontrándose diferencias significativas en las demás fracciones de glycosaminoglycanos. Este efecto diferencial es similar al ya encontrado por nosotros en cartílago.

Urine specimens from healthy children were concentrated and filtered through Sephadex G-100 and G-25. The eluate was recovered in fractions of 5 ml each. Total hexoses, galactose, total proteins and total uronic acids were determined on each fraction. Total hexoses and galactose were eluted in 6 distinct peaks. The uronic acid containing GAG were eluted in 4 small peaks on G-25 and 1 peak on G-100. This peak is eluted always with high amounts of galactose containing glycoproteins. 相似文献

The acidic glycosaminoglycans in gastric mucosa of athyroid rats: The effects of L-tri-iodothyronine
Summary Hyaluronic acid is increased about 12%, whereas dermatan sulfate is decreased about 34%, in gastric mucosa of athyroid rats when compared with controls. Administration of 2 doses of L-tri-iodothyronine reversed the effects of thyroidectomy.This work was partially supported by the Consejo Nacional de Investigaciones Científicas y Técnicas de la República Argentina. 相似文献

Zusammenfassung Pertussis Vaccine führt zu einer Hemmung der Tuberkulin-Reaktion bei Meerschweinchen. Der anti-inflammatorisch aktive Faktor wurde näher charakterisiert. Er wird von den Bakterien in das Suspensionsmedium abgegeben und ist filtrierbar, hitze-resistent und nicht dialysierbar. Er blieb widerstandsfähig gegenüber der Einwirkung von Papain, Trypsin, Desoxyribonuklease, Ribonuklease, Lysozym und Hyaluronidase. 相似文献

Riassunto L'ematoporfirina forma con il lisozima un complesso in rapporto molare 2:1. Uno dei siti di legame è rappresentato dalla regione della molecola proteica contenente la metionina-12. L'irradiamento con luce assorbita solo dall'ematoporfirina complessata consente, quindi, la fotoossidazione selettiva di tale amminoacido.
