The hypoglycemic effects of red ginsgeng-chungkukjang plus seaweeds, green laver and sea tangle, in streptozotocin (STZ)-induced diabetic rats were investigated. Five groups of male Sprague-Dawley rats weighing $140\pm10$ g (10 animals/group) were fed for four weeks with the following: nondiabetic control (NC group); STZ-induced diabetic (D group); diabetic rats fed 3% red ginseng (20%, w/w)-chungkukjang (D-RC group); diabetic rats fed RC containing 10% (w/w) green laver powder (D-RCG group); diabetic rats fed RC containing 10% (w/w) sea tangle powder (D-RCS group). Partially normalized body weight gain, FER, and blood glucose levels were observed in the D-RC, D-RCG and D-RCS groups as compared to the D group. In these three groups, serum levels of triglycerides, total cholesterol, and LDL-cholesterol were found to be lower than in the D group, whereas HDL-cholesterol levels increased. Serum insulin level in D was significantly lower than that of NC, although D-RC, D-RCG, and D-RCS almost recovered to the NC. Serum ALT activity was markedly increased in the D group, while the serum ALT levels in the D-RC, D-RCG, and D-RCS were almost the same as the NC group. Due to diabetes, hepatic xanthine oxidase (XO) activity was significantly increased and administration of red ginseng-chungkukjang or seaweeds resulted in decreased levels of the XO activity. Activity of hepatic antioxidant enzymes (superoxide dismutase and glutathione peroxidase) were significantly decreased in the D group, but the activity in the D-RC, D-RCG, and D-RCS groups were similar to that of the NC group. Results of the present study indicate that supplementation of red ginseng-chungkukjang with seaweed after the onset of diabetes ameliorated hyperglycemia via an increase in serum insulin.

New application of rice was carried out by coating the rice with the mixture solution of ginseng and chungkukjang water extract The physicochemical characteristics of the coated rice were investigated. Moisture content of uncoated (15.26%) and coated rice$(15.57\sim15.66%)$ was not different significantly. The contents of crude protein, crude fat, and crude ash of the coated rice were higher as much as $4.28\sim11.82%\;8.47\sim47.46%$, and $11.54\sim42.31%$ than those of control, respectively. As total free amino acids in coated rice were increased by augmenting the amount of the extract, total free amino acids according to rate was increased to $3.1\sim7.8$ times. The major amino acids in the coated rice was alanine$(19.56\sim39.88\;mg%)$, leucine$(5.14\sim17.66\;mg%)$, and proline$(9.98\sim16.82\;mg%)$. Of those amino acids, alanine and $\gamma-aminobutyric$ acid in only coated rice were detected to the level of $19.56\sim39.88\;mg%$ and $7.78\sim12.36\;mg%$ respectively. The calcium amount of coated rice was increased to 15% to 20%. As increasing the coating rate, hardness, cohesiveness, chewiness, and brittleness of coated rice were decreased, but springiness was increased. Before cooking, the color of coated rice appeared yellow and after cooking turned to the light yellow. The color intensity was increased feasibly as increasing the coating rate. The sensory characteristic of rice coated manufactured by adding 15% of the extract was best and found to be similar to that of the control.

홍삼청국장 추출물(RC)이 알코올을 섭취중인 당뇨흰쥐 혈당과 혈청지혈에 미치는 효과를 관찰하기 위하여 SD계 흰쥐에 streptozotocin(STZ)을 투여하여 고혈당과 고지혈증을 유발시킨 다음 홍삼청국장 추출물을 함유(g/mL)하는 $20\%$ 알코올을 매일 2 mL씩 2주간 경구투여 하였을 때의 증체량, 식이효율, 음용수 섭취량과 배뇨량, 장기중량, 혈당 및 혈청지질 함량에 미치는 영향을 조사하였다. 그 결과 RC의 식이는 STZ 투여에 의하여 증가되었던 음용수 섭취량과 배뇨량을 개선시키지 못하였으나, 감소하였던 증체량과 식 이 효율은 대조군 수준으로 회복시켰으며, 고혈당과 고지혈증도 유의하게 감소시켰다. RC는 당뇨 유발 후 에탄을 투여로 인한 사망률을 현저히 감소시켰다. 이러한 결과와 문헌상의 지견들을 종합해 볼 때, RC는 고혈당 및 고지혈증을 치료 및 예방함으로서 에탄을 섭취에 의한 사망률을 감소시킴과 동시에 당뇨에 의해 발생할 수 있는 당뇨 합병증을 예방 내지는 지연시켜주는 작용이 있을 것으로 생각된다.
