OBJECTIVETo reveal the quality variation of polysaccharides, triterpenoids and proteins in spores and fruiting bodies of Ganoderma lucidum from producing areas, different varieties, harvesting parts and periods, and wall-breaking treatments.
METHODSpores and fruiting bodies from varieties of Longzhi No. 1 and Hunong No. 1 were collected as test samples, together with wall-broken spores sold in domestic main producing areas. The anthrone-sulfuric acid colorimetric method was used to determine the content of total polysaccharides. The vanillin-glacial acetic acid-perchloric acid colorimetric method was used to determine the content of total triterpenoids. The Lowry method was used to determine the content of total proteins.
RESULTThe content ranges of total polysaccharides, total triterpenoids, and total proteins from 6 domestic main producing areas were 0.40% - 2.25%, 1.36%-3.15% and 0.74% -1.91% respectively. The content ranges of total polysaccharides, triterpenoids, and proteins in the fruiting bodies from 2 varieties cultured in Zhejiang were 0.25% -1.42%, 0.44% -1.42% and 1.82% -3.67% respectively. In addition, the ranges of samples from wall-unbroken spores were 0.41% - 0.91%, 0.09% - 0.12%, 0.78% - 0.90% respectively and wall-broken spores are 1.03% - 2.25%, 1.89% - 3.15%, 0.96% - 1.04% respectively.
CONCLUSIONThere are significant differences in the contents of main chemical ingredients of wall-broken G. lucidum spores saled in the markets. The samples from Zhejiang contain high content of total polysaccharides and triterpenoids, and samples from Fujian contains more proteins. Between the 2 major varieties cultured in Zhejiang, Longzhi No. 1 contains higher content of triterpenoids, but Hunong No. 1 has more polysaccharides. Contents of triterpenoids and polysaccharides from wall-broken spores are much higher than those of fruiting bodies. The stipes from fruiting bodies contains more polysaccharides than those of the pileus, while the triterpenoids contents are higher in the pileus than stipes. The pileus and stipes collected in the second year contain higher content of polysaccharides than the first year's samples, but the contents of triterpenoids are lower. Wall-breaking treatment would significantly improve the extraction and dissolution rate of total triterpenoids and polysaccharides.

The oil content and fatty acid composition of Ganoderma lucidum collected from different producing areas, varieties, tissue types and growth periods were measured and analyzed. The results showed that the oil content was 23. 61%-34.17% in different domestic producing areas of China; the oil content of fruiting bodies from major varieties cultured in Zhejiang province were 0.81%-1.87%, wall-unbroken spores were 0.07%-0.24%, wall-broken spores were 27.54%-34.17%, so the oil content of wall-unbroken spores were much higher than fruiting bodies, and wall-breaking treatment would increase the oil extraction rate 150-340 times. G. lucidum spores oil was mainly composed of unsaturated fatty acid composition. oleic acid and linoleic content were 53.26%-58.16% and 10.69%-16.87% respectively. Fatty acid composition ratio of spores and fruiting bodies were significantly different by PLS-DA. Determining the composition of fatty acid, especially the content of oleic acid, stearic acid and palmitic acid, could identify the tissue types of G. lucidum products' sources. In addition, the study result showed that the spores and fruiting bodies collected in the first year contained richer oil and fatty acid than second year's samples from the same variety of G. lucidum.

AIM:To observe the situation of rat retinal tissue DNA damage at early diabetic period, discuss the role of the blood glucose fluctuations, and provide a new method for studying the pathogenesis of diabetic retinopathy ( DR) .
METHODS: SD rats were randomly divided into four groups:normal control group (NC), normal fluctuation group ( NF ) , diabetes group ( DM ) and diabetes fluctuation group ( DF ) . Diabetic models were established through intraperitoneal injection of STZ. A certain amount of glucose was injected in the rats of group NF and DF in an intraperitoneal mode three times a day after the model was established, thereby causing blood glucose fluctuations. Rats were killed and the retinal tissues were taken in the 8th week. Single cell gel electrophoresis ( SCGE ) technique was adopted for detecting DNA injury extent in the retina tissue.
RESULTS:Groups NF and DF showed significant and regular fluctuations. The curve of blood glucose fluctuations was relatively stable. All values of MBG, SDBG, LAGE and M were significantly increased compared with group NC. Group DF was increased more significantly. It was statistically significant (P<0. 01). SCGE showed that there were DNA damages in different levels in the cells of group NF, DM and DF. Indicators of cells such as TL, TDNA %, TM, OTM were higher than that in group NC. It was statistically significant ( P<0-01). The comparison difference between two groups was also significant (P<0. 01).
CONCLUSION: Rat retinal tissues have DNA injury during early diabetic period. DNA injury is gradually aggravated with blood glucose fluctuation. It indicates that high blood glucose and blood glucose fluctuation are involved in the mechanism of cell DNA injury, and they may be one of DR early event, have played a certain role in the incidence of DR.
