1. Complex carbohydrate fractions were extracted successively with 40% aqueous EDTA (pH 7.4) and 6M urea (PH 7.8) FROM ACETONE-DRIED bone powder of rabbit femur. 2. The carbohydrate fraction extracted with EDTA (E=Fr) was separated into five fractions,D1approximatelyD5 by DEAE-Dephadex A-50 column chromatography. Chemical and infrared spectral analyses, and(More)
BACKGROUND Japanese cedar (Cryptomeria japonica) pollen is one of the most prevalent sources of the allergens that elicit rhinitis and conjunctivitis. Only Cry j 1 and Cry j 2 have been well characterized as the major allergens of this pollen. OBJECTIVES The aims of this study were to complete the repertoire of C. japonica pollen allergens, to investigate(More)
To elucidate precise chemical nature of urinary keratan sulfate (KS) of Morquio's disease, crude glycosaminoglycans (GAG) were separated from 24-hr urines of 3 patients with Morquio's disease and from pooled urine of a healthy boy, using cetylpyridinium chloride. KS fractions were then separated from the crude GAG after removal of other GAG and acidic(More)
The timing of DNA replication of heterochromatin in malePlagiochila ovalifolia was investigated by the use of3H-thymidine autoradiography. The estimated duration of the mitotic cycle was as follows: S period, 19 hr: G2+prophase, 10 hr; G1+meta-, ana-, telophase, 5 hr; total mitotic cycle, 34 hr. The first appearance of silver grains over the chromosomes was(More)
A highly specific, sensitive and reproducible high-performance liquid chromatographic method was developed for the determination of a new H2-receptor antagonist, N-[3-[3-(piperidinomethyl)phenoxy]propyl]-2-(2- hydroxyethylthio)acetamide.2-(4-hydroxybenzoyl)benzoate(Z-300), in rat, dog and human plasma, Z-300 base was isolated from the plasma using a(More)
