This experiment was conducted to investigate the propagation system by seed to check growth, flowering, and making seed of four-year-old seedling cactus of potted Astrophytum asterias 'Nudum', A. asterias 'Super Kabuto', and A. myriostigma 'Nudum'. Plant height and width of Astrophytum asterias 'Nudum' and A. asterias 'Super Kabuto' was 5.3 to 5.5 cm, and 2.5 cm. However, plant height and width of A. myriostigma 'Nudum' was 7.6 cm and 5.6 cm as divided into 8 sections of body. In A. asterias 'Nudum', the mean seeded pod from April to September was 37.0% and the number of seeds in a pod was 43.0. In A. asterias 'Super Kabuto', the mean seeded pod from April to September was 22.5% and the number of seeds in a pod was 26.2. However, the mean seeded pod of A. myriostigma 'Nudum' from April to September was 32.3% and the number of seeds in a pod was 57.4. Especially, the seeded pod and the number of seeds in a pod of A. asterias 'Nudum' in July was the highest, 72.0% and 66.0. The sib crossing obtained much more seeded pods and the number of seeds per pod than that of selfing in the Astrophytum. The self crossing was formed from 9.0 to 20.0% of seeded pod, and 12.0 to 16.0 seeds in a pod. However, sib crossing was formed 60.0% seeded pod and 68.0 seeds in a pod on July of A. myriostigma 'Nudum'.

The fruit and stem of Opuntia ficus-indica var. aboten (OFS), a native plant of Jeju Island, are considered a safe food source. Moreover, stem extracts have been previously reported to possess a variety of biological effects (e.g. anti-inflammatory and anti-oxidant, including the ability to partially ameliorate cognitive impairment), suggesting that this plant may have utility as a functional food. The present study investigated whether fermentation by lactic acid bacteria enhances the biological effects of OFS extracts. The acetylcholinesterase (AChE) inhibitory activity of fermented or non-fermented OFS extracts was evaluated, and the content of marker components dihydrokaempferol (DHK) and quercetin-3-methyl ether (3-MeQ) was analyzed using high-performance liquid chromatography. Fermented (relative to non-fermented) OFS extracts exhibited improved AChE inhibitory activity ($IC_{50}=28.35 mg/mL$), with AChE inhibitory activity resulting from fermentation by L. plantarum ($IC_{50}=12.56mg/mL$) exceeding that resulting from fermentation by L. fermentum ($IC_{50}=17.71mg/mL$). Furthermore, fermented (relative to non-fermented) OFS extracts exhibited a 16.7 % increase in DHK content, and 3-MeQ content of OFS extracts fermented by L. plantarum and L. fermentum increased by 28.6 % and 21.4 %, respectively. Therefore, OFS stem extract AChE inhibitory activity, as well as DHK and 3-MeQ content, was enhanced by fermentation with Lactobacillus spp. This suggests that fermented OFS extracts may contribute to prevention or improvement of cognitive impairment. These data are anticipated to be useful in the development of enhanced-efficacy OFS products.

This study was performed to investigate the antiulcer effects of Opuntia dillenii Haw. on the stomach ulcer induced by restraint and water-immersion stress in rats. For this experiment, 48 male Sprague-Dawley strain were used. The experimental groups were divided into four: a control (C) and 3 Opuntia dillenii Haw. treatment groups (E-1, E-2, E-3). Each dose of Opuntia dillenii Haw. was 30 mg/kg bw (E-1), 60 mgfKg bw (E-2) and 120 mg/kg bw (E-3). The rats were allocated to each group by 12 and observed for 4 weeks. The results were as following: 1. The stomach surface pH in each group showed no significant difference, but the values of Opuntia dillenii Haw. treatment groups were higher than the value of the control group. 2. The gastric wall mucus was increased in all Opuntia dillenii Haw. treatment groups compared with the control group. Especially in E-1 difference was higher (p<0.05) and in E-2 difference was significantly higher (p<0.01). 3. At shear rate 11.25, 45.0, 90.0, $225\;sec^{-1}$, whole blood viscosity and plasma viscosity were measured. Most of the values of Opuntia dillenii Haw. treatment groups were low compared with that of the control group. At shear rate 90.0, $225\;sec^{-1}$ the values of whole blood viscosity in E-1 were significantly low (p<0.05) and at shear rate 11.25, $45.0\;sec^{-1}$, more significant (p<0.01). At shear rate 11.25, 45.0, 90.0, $225\;sec^{-1}$ the values of whole blood viscosity in E-2 were significantly low (p<0.01). At shear rate $90.0\;sec^{-1}$ the value of plasma viscosity in E-1 was significantly low (p<0.05) and at shear rate 90.0, $225\;sec^{-1}$ the values of plasma viscosity in E-2 we resignificantly low (p<0.01). 4. Less severe ulcers were obsered in Opuntia dillenii Haw. treatment groups than in the control group. Especially E-1 groups tissues had only slight ulcers and necrosis of tissue was not observed in this group. From the results of this study, it can be concluded that the oral administratio-n of Opuntia dillenii Haw. results in protection of stomach ulcer by stimulating the secretion of gastric mucus and improving the gastric mucosal microcirculation.

This work is for selecting superior media which is similar to Peat Moss that is in general use as media of Gymnocalycium mihanovichii for Export such as 'Hwang wall' but lower price. The result on growth of 7 kinds of media (Peat Moss, BM6 Culture Medium, Coco Peat, Hydro Cray, Hydro Ball, Hugato, Vermiculite) which are applied watering (overhead irrigation, sub irrigation) based on bichemical analysis including chemical, physical analysis are following. The result of bi-chemical analysis shows that Coco Peat was stabilized planting after 90 days and Hydro Ball has high water holding capacity. The experimental result of growth in grafted cactus 'Hwangwall' shows Coco Peat is similar to Peat Moss on organic matter and in case of inorganic media, Hugato, Vermiculite, Hydro Cray made satisfactory results. But, the weight of inorganic media is too light to be tied. Consequently, Coco Peat and sphagnum moss as organic media has lower price and the condition of growth is analogous to Peat Moss. On the other hands, Hydro Ball was chosen as a substitute of Peat Moss in inorganic media.

Opuntia humifusa, widely distributed in the southern regions of the Korean peninsula, is known to have bioactive functions and medicinal benefits for treating various diseases such as arteriosclerosis, diabetes mellitus, gastritis, and hyperglycemia. In this study total polyphenol and flavonoid contents of fruit and its anticarcinogenic effects on human breast cancer were investigated. As expected, O. humifusa showed high concentrations of total polyphenol as well as flavonoid as compared to other kinds of cactus. Effects of the water extracts of O. humifusa on the proliferation, G1 arrest and apoptosis of the MCF-7 human breast cancer cells were also examined using the MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) assays, and G1 cycle arrest and apoptotic effect of O. humifusa were analyzed by flow cytometry. When MCF-7 cells were treated with different concentrations of hexane, ethyl acetate and water extracts of O. humifusa, water extracts of the fruit significantly decreased viable cell numbers in a concentration dependent manner. A G1 arrest in MCF-7 cells was induced as well. The overall results indicate that water extracts of fruit of O. humifusa would inhibit MCF-7 human breast cancer cell proliferation and induce G1 arrest.

Opuntia ficus-indica is widely used as folk medicine for burned wound, edema and indigestion, etc. After the adaptation of rats for seven days, OF (200mg/kg) was administered into rats intraperitoneally every day for two weeks. On the 14th day, $3.3m\ell$ of $CCl_4$ (50% $CCl_4$ : Olive oil = 1 : 1) was treated to rats and on the 15th day, they were operated. We measured the levels of total cholesterol, HDL-cholesterol, LDL-cholesterol, total lipid and triglyceride (TG) in serum and Malondialdehyde (MDA) in liver tissue. Opuntia ficus-indica and $CCl_4$-treated group (OFC) significantly decreased lipid peroxidation by 32.6% compared to $CCl_4$-treated abnomal group (CTA). Total lipid and TC of OFC administered group were lower than those of CTA group. Cholesterol levels showed significant effect in OFC group. Total cholesterol and LDL-cholesterol in OFC administered group were decreased by 12.7% and 17.4%, respectively, compared to those of CTA group. HDL-cholesterol in OFC administration group was increased by 19.7% compared to CTA group. This finding suggests that lipid peroxidation was inhibited in the significant level when $CCl_4$-induced rats were treated with OF. Based on this analysis, further study to identify the active components in this sample is warranted.
