In this study, the effects of HP4060, a pomegranate extract, on Sprague-Dawley (SD) female rats were investigated. SD rats used in the experiment were divided into 3 groups: a control group, 100 mg HP4060/kg rat powder fed group, and 25 mg HP4060/kg rat liquid fed group. After 20 days of administration, the changes of the brain neurotransmitters were measured. The data showed that the concentration of the serotonin and the norepinephrine were increased, whereas that of the epinephrine was decreased in HP4060 administered groups. In addition, the improving effect of HP4060 on depression symptom of menopause women were shown by increased immobility time of the SD rates in a separate experiment. The uterus weight of HP4060 fed groups were also shown to be increased. In order to monitor toxic effect of HP4060, glutamic-oxaloacetic transaminase (GOT) and glutamic-pyruvic transaminase (GPT) levels were measured, and the results showed that no significant difference in GOT and GPT levels among experimental groups implying no significant toxic side effects of HP4060. According to these results, it seems clear that HP4060 may improve symptoms of hot flush and depression caused by menopause without significant level of toxic effects.

This study was canied out to ddermine optimum areas for various sizes of land coverage of the farm machinery utilization in 1993-1994. A kind of machinery size and work systems were classed as the power tiller of 10HP+man power, the tractor of 35~46HP (tractor of 64~86HP and attachment were leased to harvest work), 64-86HP+ attachment and 90- 105HP+ attachment, respectively. \ulcornerhe results are summarized as follows: 1. The optimum areas of tractors of 90~105HP, 64~86HP and the power tiller of lOHP were estimated as 21.9 (corn-rye cropping system)- 26.9ha (sorghum $\times$ sudangrass - rye cropping system), 14.7 - 22.8ha and 1.2 - 1.61ha, respectively. The break-even-point areas of the tractors of 90-105HP. 64-86HP and the power tiller of lOHP were 16.6 (corn-rye cropping system)- 19.9ha (sorghum $\times$ sudangrass - rye cropping system), 12.5 - 16.lha and 0.12-0.13ha, respectively. 2. The optimum areas (land sizes, annual field capacity) for 50 cows by feeding rate(%) of roughage to concentrate were 6.8ha, 13.6ha in the 4060, 8.5ha, 17.0ha in the 5050 and 10.2ha, 20.4ha in the 60:40, and in case of 30 cows, it were 4.lha, 8.2ha in the 40:60, respectively. In the former case for the form of work system was the trador of 90-105HP+attachment and 64~86HP+ attachment, and the latter was the tractor of 35~46HP (tractor of 64~86HP and attachment were leased to harvest work) and 64-86HP+ attachment. 3. Productiori cost for corn-rye cropping system reducted to 51.8% in 102.9 wonkg dry matter the tractor of 90~ 105HP+ attachment with 213.4 wonkg dry matter the power tiller of 10HP+ man power.
