Autosomal dominant limb-girdle muscular dystrophy with ankle joint contracture

We herein describe a Japanese family suffering from autosomal dominant limb‐girdle muscular dystrophy showing a later onset and a predilection for males. All patients developed a plantar flexion contracture of the ankles when no distal muscular weakness was evident. The serum creatine kinase activity was remarkably elevated to 55 times the normal value. These clinical features suggest a novel phenotype.

Research on the Combustion of Low Grade Pulverised Coal

Burning characteristics of an extremely high ash coal, of which the calorific value is about 2000 kcal/kg, was tested by pulverized fuel combustion with a dry system. A special test furnace was designed which would be most adequate for the combustion of such a high ash coal. From the test, results obtained are as follows : 1) High combustion rate can be expected even from shales of 65∼75% ash, with high combustion efficiency. 2) To get stable combustion of low grade coal in a dry system, the furnace wall temperature must be kept in an adequate range, 750∼1100°C.
