symmetric changes, and lack of symptoms, we suspected a metabolic storage disorder. Laboratory test results showed normal levels of -galactosidase, arylsulfatase A, hexosaminidase A and B, and -galactocerebrosidase.However, sialic acid levelswere elevated in the urine. Examination results of a skin biopsy specimen revealed a fibroblast -neuraminidase level of 0.5 nmoles/h per milligram of prote...

We report a case of a 36-year-old woman with progressive generalized myoclonus that first became apparent 9 years ago. Her younger brother had similar problems. Examination of her eyes revealed cherry-red spots. Hexosaminidase A, β-galactosidase and neuraminidase activity were normal. Although the laboratory findings were negative, cherry-red spots, progressive myoclonus and autosomal recessive...

Two new farnesane-type sesquiterpenes, hedychiols A and B 8,9-diacetate, were isolated from the methanolic extract of the fresh rhizome of Hedychium coronarium KOEN. cultivated in Japan. Their stereostructures were elucidated on the basis of chemical and physicochemical evidence. The inhibitory effects of isolated constituents on the release of beta-hexosaminidase from RBL-2H3 cells were examin...
