Six-minute walk test improved forearm skin blood flow in Tunisian obese women.

The purpose of this study was to investigate whether 6-min walk test (6MWT) would improve the forearm skin blood flow (FSBF) response to acetylcholine (ACh), an endothelium-dependent vasodilator, in Tunisian women over a wide range of BMI. The FSBF was measured noninvasively using a laser Doppler flowmeter in response to local infusion of a cumulative dose of ACh, before and after the 6MWT for 102 healthy women; the results were expressed as percentage of baseline. The 6MWT was monitored and recorded.

[Evaluation of a fluorimetric for determining the activity of amylo-1,6-glucosidase in leukocytes for confirming the diagnosis of glycogen storage disease type III].

The confirmation of type III glycogen storage disease diagnosis is based on histological explorations on to live and/or muscle biopsies that induce some problems of delay and sensitivity. The purpose of this study was to evaluate a fluorimetric technique for the determination of amylo-1,6-glucosidase activity in leukocytes, in order to confirm the diagnosis of type III glycogen storage disease. The method consists in measuring the glucose released by hydrolysis of phosphorylase dextrin limit in the presence of cellular extracts, in 50 volunteers and 18 patients suspected of glycogenosis.
