Following preparation of water extracts of Pleurotus cornucopiae fruiting body-containing ${\alpha}$-glucosidase inhibitor, their antihyperglycemic effects were examined using streptozotocin-induced diabetic Sprague-Dawley (SD)-rats. The water extracts from Pleurotus cornucopiae showed dosage-dependant antihyperglycemic effects on the streptozotocin-induced diabetic SD-rats after oral administration to 120 min on the short time test and 4 days on the long time test, respectively. The water extracts from Pleurotus cornucopiae fruiting body showed dosage-dependent hypoglycemic action after administration to 120 min and 4 days in the SD-rat and streptozotocin-induced diabetic SD-rat.

This study was conducted to determine the effect of different fiber content of rice on blood levels of glucose insulin and triglyceride in normal subject. Ilpum and Suwon 464, which have different fiber content were used for the test. Two types of rice containing 50 g of carbohydrate were pressure-cooked and fed to ten healthy male volunteers after an overnight fast. After a meal, the 60-min blood glucose levels of Suwon 464 and Ilpum were 90.3$\pm$4.8 mg/dL and 111.6$\pm$2.7 mg/dL, respectively (p<0.01). And the 120-min blood insulin levels of Suwon 464 and IlPum were 2.9$\pm$0.8 mg/dL and 7.7$\pm$1.6 mg/dL, respectively (P<0.05). There was no significant difference in triglyceride level between two rice varieties. The calculated glycemic index (GI) was 64.5% for Suwon 464, suggesting that Suwon 464 high in fiber can be useful in low-GI diets.

The purpose of this study is to investigate tile effects of the Paecilomyces japonica on blood glucose in non-insulin dependent diabetes mellitus volunteers. During the 3 months of the experimental period, freeze-dried powder of Paecilomyces japonica (2 g/meal) was given to the subjects right before each meal. Paecilomyces japonica caused a significant decrease of $27.5\%\;and\;35.5\%$ in fasting and postprandial blood glucose levels, respectively. There were significant reductions of $28.5\%\;and\;33.5\%$ in fasting and postprandial blood glucose levels of the male subjects, respectively Paecilomyces japonica also significantly decreased in fasting and postprandial blood glucose levels of $26.1\%\;and\;37.3\%$ in female patients after treatment. This study shows that Paecilomyces japonica supplementation significantly lowered the fasting and postprandial glucose levels in NIDDM patients. These effects presumably contribute to the hypoglycemic activity.

This study was designed to investigate whether Loranthus parasiticus extract (LPE) could inhibit the activities of carbohydrate digestive enzymes and alleviate postprandial hyperglycemia in diabetic mice. Lyophilized L. parasiticus was extracted with 80% ethanol and concentrated. The inhibitory effects of LPE on carbohydrate digestive enzymes were evaluated by examining α-glucosidase and αamylase, and it was seen to inhibit the activities of both enzymes in a dose-dependent manner. More specifically, the IC50 values of LPE against α-glucosidase and α-amylase were 0.121±0.007 and 0.157±0.004 mg/ml, respectively, significantly lower than those of acarbose, showing that LPE has stronger inhibitory effects than the positive control. These results suggest that LPE strongly inhibits the activities of these digestive enzymes. Blood glucose levels in the control group of diabetic mice increased to 490.00±28.52 mg/dl and 474.60±25.30 mg/dl at 60 and 120 min after a meal, respectively. However, when LPE was added to starch, postprandial blood glucose levels were significantly reduced (463.0±23.73 and 418.5±24.50 mg/dl at 60 and 120 min, respectively; p<0.05). The area under the curve also significantly decreased following administration of LPE, with no cytotoxicity. These results therefore indicate that LPE could be used as an α-glucosidase and α-amylase inhibitor and delay carbohydrate digestion and, thus, glucose absorption after a meal.

The purpose of this study was to investigate the revascularization and reinnervation of calcitonin gene-related peptide immunoreactive nerves in immediately replanted rat molars. First maxillary right molars in 56 rats(35days old) were extracted and immediately replanted. The rats were killed 1, 2, 3, 7, 14, 28 and 42 days after replantation and revascularization of pulpal blood vessels were examined microangiogram with korean traditional ink and reinnervation of pulpal nerve were examined immunohistochemical method using calcitonin gene-related peptide(CGRP) antiserum. The results were as follows; 1. Revascularization and reinnervation of CGRP immunoreactive nerve fibers were observed mesial side whole pulp tissue of replanted teeth. Revascularization and reinnervation of CGRP immunoreactive fiber were made at 2days after replantation in entire pulp of replanted teeth and the distribution density of blood vessels were gradually increased according time elapsed, but did not achieve the density of control. 2. Postoperative dentin formation in replanted teeth revealed at 1week after replantaton and gradually increased according to time elapsed. 3. Revascularization and Reinnervation of CGRP immunoreactive nerve fibers were established at the same time and it seems to be closed relatationship between revascularization and reinnervation.

냉전종식후, 세계항공 산업계는 군수물량의 감축으로 어려움을 겪었다. 그러나 지난해부터 회복세를 보이면서 대형여객기, 지역여객기, 비즈니스 제트기와 전투기 등 항공산업 전분야가 ''''91년 이후 최대 호황기를 맞고 있다. 한편으로 보잉과 맥도널더글라스의 합병에 영향을 받은 유럽은 항공·방위산업 통합을 위한 작업에 들어갔고, 올해는 가시적인 윤곽이 나올 것 같다. 따라서 세계항공산업 제조업체들은 어느해 보다도 분주한 한해가 될 전망이다.

1. 각종농업의 독성은 25,000배에 있어도 그 피해는 막중하고 화아불능을 인정할수 있다. 2. 각종농약첨식후 수회의 식하로는 농도의 차에 따라서 다르지만 우선 토사 하고 후에 토액하는 현상을 볼수 있다. 3. 영견에 있어 대부분 견형을 인정할 수 없고 정상견의 형상은 극소수였다.
