In vitro studies were initiated to study the antitumour effect of protein-doxorubicin (DXR) conjugate on the growth of the multidrug resistant rat ascites hepatoma cell line, AH66DR. The 50% inhibitory concentration (IC50) for DXR in AH66DR cell line was 16 mumol l-1 (AH66 parental cell line, AH66P, IC50 was 0.08 mumol l-1). Treatment of AH66P and AH66DR(More)
The appearance of reactive astrocytes following brain injury was investigated in 4-week-old rats with special reference to their proliferation and chronological changes in the cytoskeletal proteins. Two days after the injury, glial fibrillary acidic protein (GFAP)-positive cells had increased in number around the lesion and spread to the entire ipsilateral(More)
The imprinting behavior of chicks was quantified as a preference score (correct response ratio) achieved in a running wheel apparatus. A total of 249 chicks were exposed to an imprinting stimulus and tested for stimulus-approaching behavior. The chicks were then classified as good learners (imprinted), poor learners (non-imprinted) and a gray-zone group,(More)
The 13C-label incorporation into glutamate, glutamine, aspartate and gamma-aminobutyric acid (GABA) from [2-13C] glucose was measured by 13C nuclear magnetic resonance (NMR) spectroscopy to directly examine the effects of ammonia on the activity of pyruvate carboxylase (i.e., the anaplerotic pathway) and the amino acid metabolism in the rat brain in vivo.(More)
A method for spatially three-dimensional (3D) localized two-dimensional (2D) 1H-13C correlation spectroscopy, localized HSQC, is proposed. This method has the following special feature in the preparation period. The 180 degrees (13C) and 180 degrees (1H) pulses are separated in time, and the 180 degrees (13C) pulse is applied at 1/4 1JCH) before the 90(More)
Shiverer is a recessive autosomal mutant characterized by the deficiency of the myelin in the central nervous system. 2',3'-Cyclic nucleotide 3'-phosphohydrolase (CNPase) activity of the various parts of the central nervous system from the Shiverer did not differ significantly from those of the control. The analysis of the protein profiles of the purified(More)
Normal cerebellar tissue, obtained from 15-day-old CBA/JNCij mouse embryos, was transplanted into the cerebellum of 4-week-old weaver mice. At the 6th week after the transplantation, the grafted tissue was distinguishable from the host cerebellum, developing a trilaminar organization. The formation of synapses by the implanted granule cells was analyzed(More)
Using chimaeras produced from the shiverer mutant with a BALB/C background (white coat color) and normal mice of the C57BL/6N strain (black coat color) by the aggregation method, the morphological patterns of the central myelin sheaths were examined by electron microscopy, with special reference to the structure of the myelin lamellae of the one genotype in(More)
Reeler, a recessive mutation in mice, causes cytoarchitectonic abnormalities to the cerebral and cerebellar cortices. In normal controls, corticospinal (CS) tract neurons retrogradely labelled after HRP injection into the lumbar cord were situated only in layer V (the inner pyramidal layer). In the reeler, by contrast, the labelled CS neurons were scattered(More)
