Fatal lipid storage disorder.

A 12-week-old female infant died from acute encephalopathy mimicking Reye syndrome. Because of positive serum hepatitis B surface antigen (HBs Ag) and perivascular inflammatory cell infiltration in the liver, she was diagnosed as having acute hepatitis. The most striking finding in the present case was extremely excessive lipid accumulation in the striated muscles including biceps brachii, tongue and cardiac muscles. The levels of serum, liver and muscle carnitine were within normal limits, though liver carnitine palmityl transferase (CPT) was markedly decreased in activity. Although the primary metabolic defect has yet to be elucidated, it is assumed that the fulminant hepatic failure induced lipid accumulation in the skeletal muscle by a certain abnormal lipid metabolism.

Isolation of an antigenic oligosaccharide fraction from Leptospira interrogans serovar canicola with a monoclonal antibody.

An oligosaccharide fraction containing the antigenic determinant of lipopolysaccharide antigen (TM antigen) from Leptospira interrogans serovar canicola, recognized by a monoclonal antibody (CT3) which agglutinates serovars canicola and broomi, was isolated by formic acid and successive sulphuric acid hydrolyses. Separation of the antigenic compounds was done by Bio-Gel P-2 and Sephadex G-25 gel filtration, and high-performance liquid chromatography with two different columns. The fraction finally obtained was a mixture of two oligosaccharides, both of which migrated as a single spot having a slightly higher mobility than an authentic tetrasaccharide (stachyose) on thin layer chromatography. The fraction contained rhamnose, arabinose and two major and two minor unknown sugars which were shown to be N- or O-acetylated and/or O-methylated sugars by nuclear magnetic resonance. The fraction inhibited the binding of CT3 antibody with TM antigen in enzyme-linked immunosorbent assay and microscopic agglutination of serovar canicola with the antibody. The inhibitory activity was destroyed by periodate oxidation or mild alkaline treatment, but was resistant to sodium borohydride reduction.

A childhood form of Huntington's disease associated with marked pyramidal signs.

The case of a childhood form of Huntington's disease in a 9-year-old boy is reported. The patient had complaints of generalized convulsions from the age of 4, and progressive motor disabilities and mental deterioration from the age of 6. His father had suffered from Huntington's disease for 10 years, and his paternal uncle and aunt, who died at the age of 52, were diagnosed as having this disease. Neurological examination revealed severe mental retardation and marked pyramidal signs. He has no signs or symptoms of involuntary movement, muscular rigidity or ataxia. Axial computed tomography showed marked dilatation of the frontal horns and suggested caudate atrophy. This case is atypical of a childhood form of Huntington's disease because of the lack of muscular rigidity and choreiform movement. But computed tomographic findings correspond to that typically seen in cases of adult Huntington's disease.
