  • Opuntia ficus-indica var. sabotan was administered with diet for 5 weeks on db/db diabetic mice and its antidiabetic activity was investigated. Leaves of Opuntia ficus-indica var. sabotan inhibited the increase of body weight, glucose elevation in blood and urine, and protein excretion in urine, and protein excretion in urine. Opuntia ficus-indica var. sabotan also inhibited the intestinal maltase and sucrase activity on db/db Mice loaded with maltose and sucrose. However, it did not significantly lower HbAlc in blood of db/db mice. These results suggest that leaves of Opuntia ficus-indica var. sabotan could be effective on insulin-independent diabetic mellitus type 2.

  • Stem rot of cacti was found at major cultivating areas including Koyang, Ansung and Eumsung of Korea in 2000. Bipolaris cactivora was consistently isolated from the lesions. The disease occurred on different species of cactus including Cereus peruvianus, C. neopithahaja f. monstruo년, C. tetragonus, Chamaeceresu silestrii, Ch. silvestrii, f. variegata, Gymnocalcium mihanovichii var. friedrichii. G. denudatum var. pentacantha, Hylocereus trigonus and Isolatocereus dumortier. Major symptoms on the cactus species except H. trigohus were almost identical. A rapid rot of the upper portion of the catus stem appeared, and became blackened and somewhat dry. On H. trigonus, the symptom was initially light yellow, water-soaked lesion, turned into light brown and dried to death. According to pathogenicity test, 10 out of 16 cactus species and varieties tested produced identical symptoms as found in the field. However, the fungi did not show pathogenicity to Notocactus scopa, Echinocactus grusonii, Eriocactus leninghausii, Lobivia nealeana, Mammillaria elongata var. intertexta.

  • total fungi 농도가 겨울철 실내${\cdot}$외 비 10배에서, 봄철 3배로 크게 감소한 이유는 겨울철 식물의 생육을 위한 화원내부 온도 및 습도가 선행 연구된 미생물 생육을 위한 환경과 유사하여 미생물의 포자 활동이 활발할 수 있고, 환기역시 봄에 비해 겨울동안 불량하여 발생한 fungi 포자가 희석되지 못했기 때문인 것으로 사료 된다. 화원의 종류별 실험결과 식물의 수가 비교적 적고 토양이 없는 절화화원과, 식물의 수가 적고 건조한 선인장화원이 bacteria 농도가 적으며, 식물의 수가 많고 양분을 공급하기위한 썩은 토양이 많은 종합식물원과 난초농장의 경우 bacteria의 수가 많음을 확인 하였다. 또한 식물의 포자 활동이 활발한 봄철에 미생물의 활동 또한 활발함을 알 수 있었다.

  • A Fusarium species was isolated from stems of cactus(Hylocereus trigonus) showing rot symptoms at Koyang, Kyonggi province in 1997. This pathogen was identified as Fusarium oxysporum based on mycological characteristics. The rot symptom appeared at the soil line and roughly circular lesions, 1∼3 mm in diameter, appeared on basal stems. The pathogen formed both microconidia and macroconidia. Microconidia were formed abundantly in false-heads on short monophialides, oval to kidney-shaped. Macroconidia were slightly sickle-shaped, 3∼5-septated with an attenuated apical cell and a foot-shaped basal cell. Colony color on PDA was white, peach or purple. Chlamydospores were formed abundantly on PDA. The pathogen was able to cause stem rot symptoms to cactus by wound inoculation as well as non-wound inoculation.

  • The Opuntia ficus-indica extract(OFE) has been claimed to have several therapeutic properties including anti-inflammation and anti-rheumatoid arthritis in oriental medicine but little is known about their effect on macrophages. This study demonstrated that OFE could stimulate TNF-alpha production in cultured macrophages. which is one of important mediators in autoimmune diseases including experimental autoimmune encephalomyelitis(EAE). In vivo study showed that oral administration of OFE exacerbate the onset of clinical paralysis. This finding suggests that OFE stimulates cytokine production and exacerbates autoimmune inflammatory diseases including EAE.

  • This study was carried out to investigate the effect of simple hydroponic culture in cultivation of grafted cactus. The results obtained are as follows: Growth indexes of grafted cactus cultivars, such as scion diameter, fresh weight, and scion hardness were improved in simple hydroponic culture compared with soil culture regardless of cultivars. Stem rot and rate of non-graft take were lower in simple hydroponic culture than in soil culture, but no significant difference was monitored between cultivars. Time for harvesting was fast in simple hydroponic culture compared with soil culture. Marketable yield increased in simple hydroponic culture.

  • We have examined radical scavenging effects, tyrosinase inhibition activities and anti-allergic activities on the methanol extracts of Opuntia ficus-indica cultivated in Cheju island. By the comparison of the four samples, methanol and 50% methanol extracts of respective fruits and stems of Opuntia, the most desirable activities were obtained in the sample of the stem's methanol extracts. Based on this analysis, further study to identify the active components in this sample is warranted.

  • This study was performed to know the potentialities of the fruits of Opuntia ficus-indica, as a medium for mushroom mycelial culture. Five mushroom mycelial (Agrocus blazei, Grifola frondosa, Hericium erinaceum, Innonotus obliquus, Phellinus linteus) were frown on the malt extract broth (MEB) and the cactus broth medium (CB). The submerged culture mixtures were extracted using equal volume of ethyl acetate, and their extract yields, total polyphenol contents, and some physiological activities were compared with each other Each extract from mycelial culture grown on CB medium showed remarkable enhancement in physiological activities compared with each counterpart grown on MEB. Among five mycelial cultures grown on CB medium, the extract yield and polyphenyl content were highest in the extract from Grifola frondosa (extract yield, 0.4 g/L and polyphenol content, 22.7%). Also, the extracts from Grifola frondosa showed the highest physiological activities, such as DPPH radical scavenging ($IC_{50}=362.9{\mu}g/ml$), xanthine oxidase inhibition (about 80% at $500{\mu}g/ml$), and superoxide radical scavenging (about 80% at $500{\mu}g/ml$), and NO production inhibition ($IC_{50}=43.1{\mu}g/ml$) in LPS-stimulated RAW 264.7 cells. This result suggests that the fruit of Opuntia ficus-indica can be used as a culture medium for improving the functional properties of various mushroom mycelia.
