acid alpha-glucosidase (EC 3.2.1.20) was purified from fetal bovine muscle by affinity chromatography on concanavalin A and Sephadex G-100 and added to the culture medium of mature muscle cultures from animals affected by glycogenosis type II. The enzyme activity in homogenates of treated cultures was significantly increased within 4 h of the addition of(More)
The biochemical and morphological properties of cultured skeletal muscle from calves born into a herd of cattle, which are heterozygous for glycogenosis type II, were studied over 17 days. Muscle was cultured by a modification of the explant technique in which the mononucleated cells that grew from the explants were subcultured. Skeletal muscle from animals(More)
Developmental changes in the concentration of adenosine 3':5'-monophosphate (cyclic AMP) and the effects of glucagon and epinephrine were studied in the perinatal rat liver. Hepatic cyclic AMP concentration doubled during the last day of gestation. After birth, the cyclic AMP concentration continued to increase and maximal levels were observed on the fifth(More)
Hereditary angioedema (HAE) is a rare autosomal dominant disease, characterized by episodes of edema typically involving the skin, gastrointestinal tract and larynx. We here describe the epidemiologic and clinical characteristic of a series of 58 patients with diagnosis of HAE, 53 (91%) type I and 5 (9%) type II. The mean age at first symptom was 10.8 +/-(More)
Adding acid alpha-glucosidase to cultures of Pompe's disease muscle has resulted in enzyme uptake and reduction in concentration of glycogen. However, bone marrow transplantation has been unsuccessful as a treatment. Immune rejection may have contributed to this failure. Twin calves share a placenta and carry lymphoreticular cells of each other's type, they(More)
Harmonisation of risk assessment (RA) is one of the priorities for sound chemical management set by Chapter 19, Agenda 21 of the United Nations Conference on the Environment and Development (UNCED) 1992 Earth Summit. The benefits of harmonisation are self evident and include transportability and consistency of RA outcomes, transparency and efficiency of(More)
