Cordyceps is reputed for its broad biological activities and as a tonic for replenishing vital function in Chinese traditional medicines. As an attempt to obtain fundamental data for the development of a new type Cordyceps, the effects of the fruiting bodies of cultivated fungus of Paecilomyces japonica grown on silkworm larvae on hyperglycemia induced by streptozotocin(STZ) and by epinephrine in rats and in mice as well as on immunological functions in mice were investigated. The 70% methanol extract of the fungus, when administered orally at 100 and 300 mg/kg in STZ-induced hyperglycemic rats, caused a significant decrease in blood glucose level 3hr after sample treatments. The methanol extract, when administered p.o. at the same dose levels in epinephrine-induced hyperglycemic mice, also caused a significant decrease in serum glucose levels as well as a significant reversal of the liver glycogen contents suggesting its hypoglycemic activity might be due to glycogen breakdown in the liver. Treatment of normoglycaemic mice with the methanol extract of the fungus exhibited a significant glucose tolerance up to 3hr after oral glucose load(2.0 g/kg). The methanol extract also showed immuno-stimulating activity as measured by carbon clearance in mice and a significant antifatigue effect as measured by weight loaded forced swimming performance in mice.

N/A DKY is an oriental drug preparation composed of 17 natural products and is known to have antihyperglycemic action at 100 ㎎/㎏ po in animal tests. The general pharmacological properties of DKY preparation were investigate in mice, rats, guinea pigs and rabbits. This preparation did neither show any effects on central nervous system, nor effects on algesia, nor epilepsia at the large doses of 3000 ㎎/㎏ po in mice or rats. However, the preparation showed hypothermic action at the doses of 330 and 1000 ㎎/㎏ po. In the guinea pig ileum, rat fundus strip and estrogenized rat uterus, DKY did not influence their tension at a concentration of 3 X 10^(-3) g/㎖, and the spasmogenic actions produced by histamine, ACh and 5-HT were not blocked in the presence of DKY at 3 × 10^(-3) g/㎖. The blood pressure and respiration were not considerably influenced at 10㎎/㎏ iv of DKY in rabbits. It did not influence the intestinal propulsion of mice and the normal gastric secretion of rats. These results may suggest that DKY preparation have little effects on central nervous, autonomic and gastrointestimal systems, except hypothermic action.

본 연구에 사용한 식물체는 Rubus fruticosus L. cv. BB21은 Rubus fruticosus L. ${\times}$ R. parvifolius L. 교잡 블랙베리 V3품종에서 방사선을 처리하여 돌연변이로 선발 육종된 V9개체 중 다시 방사선을 처리하여 선발육종 된 품종이다. 이러한 우량계통의 신속한 증식을 이루기 위하여 조직 배양을 통한 효과적인 방법을 구명하고자 배지 및 생장조절물질 등의 처리에 따른 안정적인 생산을 위해 본 연구가 수행되었다. 땅속에서 채집된 근맹아 절편체를 0.1, 0.5, 1.0, 2.0 mg/L BAP가 첨가된 MS와 1/2MS 배지에 치상하여 6주간 배양한 후, 다경의 형성률을 조사하였다. 형성된 다경으로부터 산업적으로 이용하기 위한 안정된 생산을 위하여, 신초의 잎을 제거한 후 절간배양을 수행하여 다수의 소식물체를 증식하고자 여러종류의 배지 즉, AD (Anderson 1980), B5 (Gamborg 1968), MS (Murashige and Skoog 1962), SH (Schenk and Hildebrandt 1972), QL (Quoirin and Lepoivre 1977), WPM (Lloyd and McCown 1981)배지와 상기의 각각의 동일배지의 무기염류의 수준을 절반으로 한 1/2배지에 배양하였다. 초기의 생육(30일간 배양 시)에 있어서 생장은 배지 간에 차이를 나타내어 1/2AD, 1/2QL 배지에서 가장 양호한 초장을 나타내었으며, 절간수도 약 3.8, 4.4개를 나타내었으며, 뿌리, 생중량 다경유도 모두 양호하였다. 90일간 배양한 경우에서는 MS배지가 초장이 가장 양호하였으며 AD, SH 순으로 양호한 결과를 나타내었다. 식물체의 토양 순화는 신초와 뿌리가 잘 발달된 정상적인 식물체를 모래, 토양, 그리고 버뮤큘라이트가 혼합된 토양(1:1:1, v/v)에 각각 직접 이식하여 실시한 결과, 식물체의 발근율과 생존률(약98%)을 나타내었다. 이상의 결과를 통하여 블랙베리 묘목의 대량생산이 가능하여 농가에 원활한 공급이 가능할 것으로 예상된다. This study was conducted to develop a simple, rapid, and reliable method for in vitro propagation of disease-free and true-to-type clones from sucker explants of thornless blackberry (Rubus fruticosus L. ${\times}$ R. parvifolius L.). To induce multiple shoots, the sucker explants were sterilized in 1% NaOCl solution, and then were aseptically cultured on the full and 1/2 MS solid medium supplemented with BAP (0.1, 0.5, 1.0, 2.0 mg/L). After six weeks of culture, the highest frequency (85.4%) of shoot formation from sucker explants was obtained on the full-strength MS medium with 1.0 mg/L BAP. Node explants obtained from multiple shoots were cultured on the various media of full- or half-strength of AD, B5, MS, SH, QL, WPM media, respectively. After 30 days of culture, plant growth was good on the half-AD, half-QL medium. After 90 days of culture, plant growth was good on the full MS and full SH medium. The survival rate of the plantlets after transfer to plastic pots containing soil mixture (sand: soil: vermiculite was 1:1:1, vol.) in the greenhouse was 98%. The results indicate that a multiple-shoot procedure can be applied for an efficient mass propagation of Rubus fruticosus L. ${\times}$ R. parvifolius L.
