Normal tissue plasminogen activator and plasminogen activator inhibitor activity in plasma from patients with type 1 diabetes mellitus.

The fibrinolytic system was investigated in 38 patients (21 males and 17 females) affected by type 1 diabetes mellitus (18 free from complications, 10 with retinopathy, and 10 with autonomic neuropathy) and in 8 healthy controls. Two separate fibrinolysis-stimulating tests were done: standardized venous occlusion and 1-desamino-8-D-arginine vasopressin infusion. Plasma tissue plasminogen activator antigen and activity and plasma plasminogen activator inhibitor activity were measured. All the patients were in good metabolic control (mean HbA1c 7.4%, range 6.1-8.0%). No significant differences were observed either between the diabetic patients and the control subjects, nor among the subgroups of diabetic patients. The fibrinolytic system is probably not involved in type 1 diabetes mellitus.

Effect of soya and cellulose fibers on postprandial glycemic response in type II diabetic patients.

OBJECTIVE: We studied the effect on serum glucose and insulin of a preprandial ingestion of 7 g of soya fibers or of an equal amount of purified cellulose on eight non-insulin-dependent (type II) diabetic patients. RESEARCH DESIGN AND METHODS: Four tests were conducted in each patient in random order. In the first study, soya or cellulose was ingested before a standard breakfast, and postprandial glucose and insulin curves were determined. In the second study, intestinal absorption was investigated by means of a standard D-xylose absorption excretion test after the ingestion of soya or cellulose. RESULTS: Insulin profiles did not differ between the two treatments. The glycemic profiles after soya ingestion were lower than those after cellulose ingestion. The area under the glucose curve and glucose peaks were significantly higher after cellulose ingestion (area under the curve 20.2 +/- 3.88 vs. 15.57 +/- 4.42 mM x min, P = .05; glucose peaks 4.97 +/- 0.76 vs. 3.77 +/- 0.77 mM, P less than 0.02). The xylose tests were in the normal range, indicating that there was no interference with exose absorption, and no statistical difference was found between cellulose and soya treatment. CONCLUSIONS: It is concluded that soya fiber compared with purified cellulose has a favorable effect on the rise of postprandial glycemia in type II diabetic patients; moreover, the use of soya fibers did not carry any untoward side effect.

[Pseudoachondrodysplasia (pseudoachondroplastic spondyloepiphyseal dysplasia). Description of 2 non-familial cases].

Two non familial cases of pseudoachondroplasia are reported. The patients, observed at 4 years and 6 months and 5 years respectively, show short-limb dwarfism with disproportionated long trunk and with normal head and face. Flattening of vertebral bodies with biconvex deformity and short tubular bones with irregular epiphyses and metaphyses are the major radiographic features. In these patients to state the type of genetic transmission is very arduous, as the genetic heterogeneity of the pseudoachondroplasia.
