Foreign body granuloma is a chronic, proliferative, inflammatory reaction caused by persistent poorly biodegradable tissue irritants. Currently, many injectable materials are being used extensively for soft tissue augmentation. Although considered biologically inert, these materials can evoke adverse reactions such as foreign body granuloma. Mainly these complications are a result of the use of unproven products injected by unlicensed or unqualified practitioners. Here we report a case of foreign body granuloma in the left lower eyelid secondary to injection of extracts from safflower seeds.

Very little research has been carried out on safflower seed for the prevention and treatment of the bone deficiency diseases, including osteoporosis, which are supported by scientific evidences. In the present study, 3microliter of 0.1% dried crude extract or 2microliter of 0.1% dried aqueous fraction were shown to significantly accelerate the rate of differentiation of osteoblast. Also, the crude extract and aqueous fraction increased the [Ca2+]i of the cultured osteoblast cells: 3microliter of 0.1% dried crude extract and 2microliter of 0.1% dried aqueous fraction significantly increased the [Ca2+]i of the cultured osteoblast cells (8x104) to the extent that it deserves a considerable attention. Furthermore, the crude extract and aqueous fraction increased the [Ca2+]i of the cultured osteoblast cells, and 300microM Cd2+, specific calcium channel blocker, completely blocked the increase. Therefore, the increased [Ca2+]i of the cultured osteoblast cells by safflower seed component continued to activate calcium channel.

The powdery mildew of safflower (Carthamus tinctorius L.) extensively occurred at 1999 at the experimental farm of Kyongsangnam-do Agricultural Research and Extension Services. Both sides of the leaves and the older stems were covered with the fungus, and then the leaves and stems turned yellow. The conidia, conidiophores and perithecia were observed on the leaf lesion. Perithecia were ellipsoidal, 80-117microm in diameter. Asci were subglobose and 84~99x59~73microm in size. Ascospore were ellipsoidal to ovoid, and 15~34x11~23microm in size. Conidia were ellipsoid to barrel-shaped, 25~37x11~22microm in size and formed in long chains. The causal organism was identified as Sphaerotheca fuliginea. This is the first report on powdery mildew of safflower caused by Sphaerotheca fuliginea in Korea.

A field experiment was conducted to measure the physiological characteristics, yield, active ingredient content, and other indicators of Carthamus tinctorius leaves undergoing 13 sowing date treatments. The principal component analysis(PCA) and redundancy analysis were used to analyze the correlation between these indicators to explore the effect of sowing date on the yield and active ingredient content of C. tinctorius in Liupanshan of Ningxia. The results illustrated that the early sowing in autumn and spring had significant effects on leaf photosynthetic parameters, SPAD value, antioxidant enzyme activity, nitrogen metabolism enzyme activity, filament yield, grain yield, and hydroxy safflower yellow A(HYSA) of C. tinctorius. Sowing in mid-November and late March had the best effect. Leaf transpiration rate, stomatal conductance, nitrate reductase, nitrite reductase, glutamine synthetase, and glutamate synthase increased by 44.9%, 52.4%, 15.9%, 60.8%, 10.3%, and 38.3%, respectively. The activities of superoxide dismutase, peroxidase, and catalase decreased by 10.8%, 4.1%, and 20.9%, respectively. The improvement of photosynthetic physiological characteristics promoted the dry matter accumulation and reproductive growth of C. tinctorius. The yield of filaments and seeds increased by 15.5% and 11.7%, and the yield of HYSA and kaempferol increased by 17.9% and 20.0%. In short, the suitable sowing date can promote the growth and development of C. tinctorius in Liupanshan of Ningxia, and significantly improve the yield and quality, which is conducive to the high quality and efficient production of C. tinctorius.

The ultimate goal of periodontal treatment is the regeneration of periodontal tissues which have been lost due to periodontal disease. Recently, many natural medicines have been studied for their potential of anti-bacterial, anti-inflammatory and regenerative effects in periodontal tissues. Safflower seeds have been traditionally used as a drug for treatment of fracture and blood stasis in oriental medicine. The objective of the present study is to examine the biologic effects of safflower seeds extract on bone formation and regeneration of rat calvarial defects. The calvarial defects were made with 8mm trephine bur and extract of safflower seeds were placed directly at these defects. 24 rats were divided into control and experimental groups, and each group was sacrificed at 1 week, 4 weeks and 8 weeks. To study a histopathology related to bone regeneration, Goldner's Masson Trichrome stain and histomorphologic measuring was done at each weeks. In the early phase of bone healing, less inflammatory infiltration and capillary proliferation was found in experimental group compared to control. Dense bony tissues and matured bone structures in defect areas were found in experimental groups. And area of new bone formation was significantly increased at 8 weeks in experimental group. These results indicate that direct local application of safflower seeds extract reduces the early inflammatory response and promotes the regeneration of new bone in calvarial defects of rats.

OBJECTIVETo investigate the optimal alcohol precipitation parameters for extract of Carthamus tinctorius.

METHODSThe effects of different factors on the transfer rate of hydroxy safflower yellow A (HSYA) was studied via single factor experiments, including the final alcohol concentration of the liquor, the speed of stirring, the initial density of the extract, the temperature and the pH of the liquor. Based on the results of single factor experiments, the final alcohol concentration of the liquor, the speed of stirring, the initial density of the extract and the pH of the liquor were studied by an orthogonal test and a multiple guidelines grading method, and the transfer rate of HSYA, the yield and the purity of extract in the supernatant were used as comprehensive evaluation index.

RESULTThe optimal alcohol precipitation process of Carthamus tinctorius extract was as follows: the final alcohol concentration of the liquor 50%, the speed of stirring 500 r/min, the initial density of the extract 1.15 g/ml and the pH of the liquor 5.0.

CONCLUSIONThe proposed alcohol precipitation process is convenient and steady with high transfer rate of HSYA, high yield and purity of extract in the supernatant.

AIMTo investigate the intraspecific variation of Carthamus tinctorius L. (safflower) and establish foundation for further breeding of safflower germplasm resource and screening the quality correlation genes.

METHODSAmplified fragment length polymorphism (AFLP) was carried out to analyze genetic variation of 28 safflower populations collected in China. Unweighed pair-group method of with arithmetical averages (UPGMA) cluster analysis was used to construct a dendrogram and to estimate the genetic distances among the populations.

RESULTSAll populations could be uniquely distinguished using 12 selected primer combinations. Similarity coefficients ranged from 0.48 to 0.96 among the populations. Dendrogram revealed distinct segregation of all the cultivars into three main groups and one midst group.

CONCLUSIONLimited genetic diversity exists within the tested 28 collections at intra specific level and AFLP-based phyiogeny was not absolutely consistent with that based on morphological characters may be due to the interaction effect between genotype and environment.
