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.

The effect of Holotrichia on natural killer cell activity in normal mouse were studied. 1. The oral administration of Holotrichia increased spleen weight about 21.1% and also cell numbers of spleen compared to control mice group. 2. The cytotoxicity of effector cell was most effectively induced in a ratio of 50 : 1(effector/target cell). 3. Cytotoxicity of effector cells was. increased about 24% as compared with control group in in vivo test. 4. On the other hand, the administration of Holotrichia original solution showed significant increase the cytotoxicity. The cytotoxicity was increased concentration dependently. 5. The cytotoxicity by $^{3}H-thymidine$ incorporation assay showed similar effect with LDH enzyme method. 6. In the purified NK cells, the cytotoxicity was increased about 31% as compared with control group in in vivo system and the ratio of cytotoxicity was generally more increased than that of partially purified NK cell. 7. In vitro experimet of the purified NK cells, the cytotoxicity was increased 11.8% as compared with control group and the ratio of cytotoxicity was also more increased than that of partially purified NK cell. These results suggest that Holotrichia is administrated to mice with malignant tumors, the increase of NK cell activity may occur and affect tumor cells.

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.

In order to establish the integrated management of white grubs in ginseng field damages of ginseng plants (Panax ginseng C.A. Meyer) by the larvae of the larger black chamfer (Holotrichia morose Waterhouse) and the Korean black chamfer (Holotrichia diomphalia Bates) were investigated. Most of ginseng damages due to H, morose usually occurred in September through October, mainly on 2nd year plants. However, the damage by H. diomphalia occurred in September through October (usually in odd number of years) on 2nd year plants and in the following May and June on 3rd year plants. Therefore, in the fall of every odd number of years, synchronized occurrence of the two species caused severe damage on ginseng plants. Both of the 3rd instar larvae of the forementioned two species damaged ginseng roots regardless of the age of the plants when ginseng plants were artificially infested with them. Ginseng fields located at the slopes with good drainage are most likely damaged by them.

The ovipositional preferences of Holotrichia morosa were investigated to defermine several environmental factors related to its incidence in ginseng fields. H. moroia paid no eggs in naked soil without ground color plants, and shouted ovipositional preference among weed plants in the order to Aurmisin prinrcps var oripntnlis, Epigrren canadensis Diuitarin sanguinalis, and Porttulaca oleracea. More oviposition was observed in the denser vegetation of D. sanguinalis and in soft soil. The egg-laying females were seldom attracted to fresh rice straw mulched on soil surface or decayred rite straw mixed into soil. The number of eggs laid by a female decreased considerably when the soil moisture content was below 5% or above 35%.

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.

Objective : Though modern medicine has made various studies in cancer treatment, the results of the treatments are not satisfactory. Considering this, Oriental medicine can be a breakthrough in treatment of cancer, and therefore, its constant research eagerly needed. According to preceding studies, Hangamjedoktang (Kangaizhidu-tang) with Hagocho appeared to be statistically significant against cancer, and therefore to seek a better medication for cancer, Holotrichia which seemed to be effective against cancer was added to the formula, and herbs which showed an anti-tumor effect in preceding studies composed Hangamyagjaebang. The efficacy of both Hangamjedoktang with Holotrichia (HJJ) and Hangamyagjaebang (Kangaiyaocaijang) (HM) was compared. Methods : To examine the anti-cancer effect of HJJ and HM, inhibitory effect on solid tumor growth in mice induced by Sarcoma-180 (s-180), change of body and organ weight in tumor bearing mice and the activity of machrophages and lymphocytes in the spleen were examined. Results : 1. In the HJJ and HM treated groups, tumor growth was markedly decreased. 2. HJJ and HM increased the activity of ALP which is produced from the splenocytes transplanted with S-180. 3. HJJ and HM increased the ACP activity of the macrophages of the mice transplanted with S-180. Conclusion : These results suggest that HJJ and HM are good candidates for new drugs for cancer therapy.
