Abstract
Chondroitin sulfate (CS) + dermatan sulfate (DS) and hyaluronan (HA) concentrations and the sulfation patterns of CS-DS in the cartilaginous tissues and alimentary canals of Honshu Sika deer, Hokkaido Sika deer, and cattle were investigated in the present study. CS + DS concentrations were high in cartilaginous tissues, namely, the trachea and scapular cartilage region (5- 12 g*), and low in the alimentary canal (~0.3 g*). HA concentrations were low in cartilaginous tissues and the alimentary canal (~0.2 g*). All tissues mainly contained A-type [HexAGalNAc(4-sulfate)] and C-type [HexAGalNAc(6-sulfate)] CS + DS. The ratios of A-type/C-type CS + DS were 1.2- 3.1 and 0.9- 16.4 in cartilaginous tissues and the alimentary canal, respectively. CS + DS predominantly comprised β-D-GlcA and α-L-IdoA in cartilaginous tissues and the alimentary canal, respectively. The alimentary canal characteristically contained up to 14 % highly sulfated E-type [HexAGalNAc(4,6-disulfate)] and D-type [HexA(2-sulfate)GalNAc(6-sulfate)] CS + DS. The specific distributions of CS and DS were immunohistochemically confirmed using CS + DS-specific antibodies. Although the omasum of cattle is more likely to have higher concentrations of CS + DS and HA, no significant species differences were observed in the concentrations or sulfation patterns of CS + DS among species for Honshu Sika deer, Hokkaido Sika deer, and cattle. (*per 100 g of defatted dry tissue).

Abstract
1. Sulphate labelled proteoglycans (PG) synthesized by cultured human arterial smooth muscle cell have been quantified using an improved method based on a combination of specific enzymes and ethanol precipitation. 2. The present method gives quantitative data of PGs and subclasses allowing batchwise analysis of a large number of samples. 3. Approximately 81% +/- 1.7% (mean +/- SD, n = 6) of total PGs synthesized by human arterial smooth muscle cells accumulated in medium. 4. In cell layer and medium chondroitin sulphate proteoglycan constituted 65.0% +/- 0.3% and 75.8% +/- 0.7% (mean +/- SD, n = 3), respectively of sulphated PGs. 5. Heparan sulphate proteoglycan accounted for 26.8% +/- 0.6% in cell layer and 22.6% +/- 0.5% (mean +/- SD, n = 3) in medium of sulphated PGs.

Abstract
A model for smooth muscle derived foam cells was developed by treating smooth muscle cells isolated from the aortae of neonatal rabbits with beta VLDL for up to 1 month. Hyperlipidemic beta VLDL isolated from cholesterol fed rabbits induced proliferation of the cells that were maintained in lipid deficient serum. In addition, the lipoprotein fraction stimulated [14C]oleic acid incorporation into [14C]cholesteryl ester, even in cultures that had been chronically exposed to the lipoprotein. The accumulation of cholesterol was evaluated and small amounts of cholesteryl ester were demonstrated in cultures treated for 3 days with beta VLDL. However, continued exposure to the lipoprotein resulted in larger elevations in total cholesterol, approximately 65% of which was in the esterified form in cultures treated with 100 micrograms beta VLDL/ml for 24 days. When cholesterol levels were examined as a function of time, it was determined that both total cholesterol and cholesteryl ester levels increased. Approximately 2-3 weeks after lipoprotein was introduced to the culture, maximum levels were attained. Triglyceride levels were also measured and found to increase more than two-fold in cultures that had been incubated in the presence of beta VLDL for 24 days, when compared to cultures incubated in its absence. Examination of the cultures by electron microscopy revealed intracytoplasmic lipid droplets in beta VLDL treated cells. These results suggest that beta VLDL treatment of neonatal aortic smooth muscle cells provides an ideal model in which to study the lipid laden smooth muscle cells that characterize the atherosclerotic plaque.
