Objective: To study the mechanism of the preventive effects of soybean isoflavones on osteoporosis. Methods: The serum collected from experimental rats given soybean isoflavones extract was added to the culture system of osteoblast cells (OB) isolated from the calvaria of neonatal SD rats. MTT assay was employed to determine cell proliferation. The activity of alkaline phosphatase (ALP) and bone gla protein (BGP) were determined by ALP and BGP Kits. The content of IL 6 secreted by OB was determined by ELISA Kit. Results: Isoflavones could stimulate OB proliferation, elevate the activity of ALP and BGP level. They had no apparent effects on the secretion of IL 6. Conclusion: Soybean isoflavones can promote proliferation and differentation of OB in vitro and have no remarkable influence on bone absorption. The effects of soybean isoflavones on osteoporosis seem to depend on stimulation of bone formation rather than suppression of bone absorption.

Objective To observe effect mechanism of L-arginine (L-arg,a precurory substance of nitric oxide sythesis) in proveting proteinuria in adriamycin-induced nephrosis model of rats.Methods Nephrosis model of 16 rats was established by tail vein injetion with adriamycin,then the 16 rats were divided into two groups;model group and treatment group with L-arg administration (treated group),the levels of nitric oxide(NO),endothelin-1(ET-1),renal function,and pathological changes were observed in the two groups.Results The successful nephrosis model of rats was indentified with optical and electron microscope technique.Proteinuria was occurred in the two groups,but proteinuria degree in treated group was lighter than those of model group,however NO level was higher than that of model group,there was negatively correlation in the levels of NO and ET-1 between both groups,pathological alteration under electron microscope observation was obviously less in the treatment group than those of the model group.Conclusions On basis of these findings,author consider that the L-arg could reduce proteinuria output by promoting NO synthesis and suppress the ET-1 production.

Objective To understand the characteristics of indoor PM2.5 pollution in residential houses in Guangzhou. Methods Indoor PM2.5 samples were collected in nine residential sites using mini-volume sampler in Guangzhou in summer (June to July, 2003). Mass concentration of PM2.5 and the organic carbon (OC) and elemental carbon (EC) levels in PM2.5 were measured. Results The average concentration of PM2.5 was (47.4?17.7) mg /m3, a relatively high concentration compared to the previous studies in other cities. The OC and EC concentrations in PM2.5 were (12.5?8.7) and (4.4?2.3) mg /m3 respectively. OC and EC counted for 24.6%?5.6% and 9.9%?4.8% in indoor PM2.5. However, it was estimated that OC mainly came from indoor sources and EC related well with outdoor sources, which conformed to the source investigation. Conclusion Cooking, smoking and outdoor sources are the prominent contributors to the indoor PM2.5 pollution. Housing conditions such as decoration and ventilation may affect the indoor PM2.5 level.
