Objectives : Etiological studies of diabetes and its complications showed that oxidative stress might play a major role. Therefore, many effects have been fried to regulate oxygen free radicals for treating diabetes and its complications. Because Holotrichia has been known to be effective for the treatment of diabetes, the methanol extract of Holotrichia was tested for its effectiveness in reducing the oxidative stress induced by streptozotocin. Methods : Holotrichia was washed, dried in the shade and crushed. The crushed Holotrichia was extracted 3 times, each time with 3 volumes of methyl alcohol at $60^{\circ}C$ for 24h. The extract was filtered and evaporated under a reduced pressure using a rotary evaporator to yield 17 g. Holotrichia extract was oral-administed to the diabetic rats induced by streptozotocin 50 mg per 1 kg of body weight for 20 days. The efficacy of the Holotrichia extract was examined with regard to the enzymatic pathways involved in the oxygen free radical production and the glutathione balance. Results : The Effects of the methanol extract of Holotrichia in streptozotocin-induced diabolic rats with regards to body weight, blood glucose level, hepatic lipid peroxide level, hepatic superoxide anion radical content. hepatic xanthine oxidase activity and type conversion rate, hepatic glutathione level, hepatic aldose reductase activity, and hepatic sorbitol dehydrogenase activity were shown to be good enough to cure and prevent the diabetes and its complications. Conclusions : These results indicated that Holotrichia might reduce the oxidative stress in the tissues and organs by regulating the production of oxygen free radicals. Especially, Holotrichia might prevent and cure the diabetes and its complications by reducing the oxidative stress in the ${\beta}$-cells of pancreas. Some suggestions on biophoton experiments were made.

Holotrichia was tested for the effects on damages of liver tissue induced by bromobenzene. Holotrichia was treated firstly into samples, and then bromobenzene intoxicated animal models were set with them. In vitro, the level of lipid peroxide in tissue of liver proportinally decreased with the level of concentration of extract prepared from Holotrichia It was much more decreased, when lipid peroxidation was induced with ferrous iron ($Fe&{+2}$). In vivo, after the extract was administered to the animal model for twenty days, the level of lipid peroxide in liver decreased compared to that of bromobenzene-treated group. The enzyme activities of epoxide hydrolase and glutathione S-transferase in liver highly increased in Holotrichia pre-medicating group compare with the group treated with only bromobenzene. And we can get the same results in the enzyme activities of superoxide dismutase, catalase and glutathione peroxidase. The level of glutathione followed by Holotrichia pre-medicationg administration, increased as highly as normal group in compare with the group treated with only bromobenzene. Also, the enzyme activities of AL T, AST and $\{gammer}-GTP$ in liver considerably decreased. In conclusion, Holotrichia recovers the damage of liver due to bromobenzene intoxication by the increased activities of lipid peroxidation and bromobenzene scavenging enzymes.

A thrombus is a mass formed from the constituents of the blood within the vessels or the heart during life. The process of its formation is known as thrombosis, It has been generally accepted that Holotrichia is an useful medicine for thrombosis. The rate of fibrinolysis of Holotrichia extracts increase as incubation times. Especially 52 days, the effect on the extracts has an maximum increased fibrinolytic activity, Heat-and-pH-stability of the extract on fibrinolysis is relative to temperature, At $37^{\circ}C$, it has activating effect between pH 4 and pH 12. At higher temperature, especially $80^{\circ}C$, an excessive increase in temperature has a deactivating effect on the extracts. Optimal pH of the extract on fibrinolysis is between pH 7.0 and pH 8.5, it is effective within a relatively broad pH range. In experiments of various inhibitors of Holotrichia extracts fibrinolytic activity, there are strong inhibitive effect on SBTI and Aprotinin, and a few inhibitive effect on DFP and t-AMCHA, no effect on PSMB and TLCK. Holotrichia extracts mixing with fibrinogen are observed Electron microscopy. it shows partially erosive-shaped fibrinolytic activity. In a SDS-PAGE of the extract having the fibrinolytic activity, three bands are found, protein 1, 2 and 3 having a molecular weight of 30,000, 45,000 and 60,000 Dalton.

인삼의 주요 해충의 하나인 큰검정풍뎅이의 발생요인을 구명하여 효율적인 방제대책을 수립하기 위해 몇 가지 환경요인에 대한 산란선호성을 조사한 결과 큰검정풍뎅이는 지피식물이 없는 나지에는 전혀 산란하지 않았고 식물의 종류에 따라서도 차이를 보여 쑥. 망초, 바랭이, 쇠비름 등에는 잔디나 달맞이꽃에 비해 산란수가 많았으며, 토끼풀에는 산란하지 않았다. 지피식물이 바랭이일 때 지피도 높은곳, 토양경도가 낮은 곳에서 산란수가 많았다. 지피물이 볏짚인 곳은 산란수가 있어 나지와 유의차를 보이지 않아 볏짚은 산란유인으로 작용하지 않는 것으로 생각되며, 토양내의 부숙볏짚 역시 산란수에 영향을 미치지 않는 것으로 보였다. 또한 과건 또는 과습토양에서는 산란수가 현저히 감소하였다.

This study was carried out to examine mechanisms by which Holotrichia (HTC) produces protective effect against renal cell injury. HTC extraction (5%) prevented $H_2O_2(50mM)$-induced LDH release and lipid peroxidation in renal cortical slices. When slices were treated with 5% HTC extraction, cellular glutathione content and the superoxide dismutase activity were not altered in control and $H_2O_2$-treated tissues. When slices were treated with 50 mM $H_2O_2$, the catalase activity was significantly inhibited, which was completely restored by addition of 5% HTC. Treatment of slices with 5% HTC extraction increased the glutation peroxidase activity in $H_2O_2$-treated tissues. These results suggest that HTC prevents oxidant-induced cell injury and lipid peroxidation by increasing the activities of catalase and glutathione peroxidase in renal cortical slices.
