In this study, the antioxidant effect of Chungkukjang supplementation against memory impairment and oxidative stress in scopolamine (2 mg/kg i.p)-injected mice was investigated. The experimental animals were divided into five groups and fed experimental diets for 12 weeks; normal diet group (C), scopolamine + normal diet group (S), scopolamine + 63.0% soybean Chungkukjang supplementation group (SS), scopolamine + 45.0% Yakkong Chungkukjang supplementation group (SY), and scopolamine + 50.0% black foods such as black rice, black sesame seeds, and sea tangle added Yakkong Chungkukjang group (SYB). For the results of food intake, body weight gain, and brain weights, levels of scopolamine-injected groups were lower than the levels of the control group. The reduced brain weight of the scopolamine-injected group (S) was regulated to control level by supplementation of three types Chungkukjang. In the oxidative stress indicator, nitric oxide and malondialdehyde levels in serum of scopolamine-injected mice were higher than those of other groups. However, supplementation of soybeans, Yakkong and black foods added Yakkong Chungkukjang was proven to regulate them. Antioxidant enzyme activities such as superoxide dismutase (SOD) and glutathione-S-transferase (GST) in serum showed no significant differences among the groups. The reduced levels of vitamin A and vitamin E in serum and brain tissue of scopolamine-injected mice were controlled by supplementation of three types of Chungkukjang. Total antioxidant capacity (TAC) of scopolamine-injected group was lower than those of other groups. However, TAC was significantly elevated by Chunggukjang supplementation. Therefore, antioxidative effects of soybeans, Yakkong, and black foods added Yakkong Chungkukjang supplementations against oxidative stress in scopolamine-injected in mice could expected.

Sixteen species of algae (4 species of green algae, 5 species of brown algae and 7 species of red algae) were collected from the coast of Chungmu, Gyeongnam, from June to October, 1976. The content of minerals in algae were analyzed by Atometic Absorption Spectrophotometer. The results were as followed 1) The content of Iron and Nickel in green algae were abundant, and those of Lead, Nickel and Manganese in brown algae were low. 2) The content of Cadmium were in the range of 0.58-1.04ppm (average: 0.85ppm) in green algae, 0.32-2.10ppm (average: 1.08ppm) in brown algae and 0.54-1.70ppm (average: 1.04ppm) in red algae. The content of Cadmium were in the range of 0.3-0.6ppm in laver, Porphyra tenera, sea mustard, Undaria pinnatifida, and tangle, Laminaria japonica, but its content was lower than those expected. 3) The content of Lead were in the range of 0.67-1.40ppm (average: 1.03ppm) in green algae, 0.60-1.00ppm (average: 0.82ppm) in brown algae, 0.56-2.40ppm (average: 1.28ppm) in red algae and its content in algae were lower than in fish and shellfish. 4) The content of Copper were in the range of 10.8-24.2ppm (average: 18.95ppm) in green algae, 7.4-24.6ppm (average: 18.16ppm) in brown algae, 6.4-31.2ppm (average: 19.94ppm) in red algae and those content were considerably abundant except for some algae. 5) The content of Nickel were in the range of 5.4-16.6ppm (average: 9.1ppm) in green algae, 1.0-4.4ppm (average: 2.32ppm) in brown algae and 0.7-4.6ppm (average: 2.59ppm) in red algae. 6) The content of Iron were in the range of 686.4-1159.0ppm (average: 916.5ppm) in green algae, 131.0-499.2ppm (average: 310.16ppm) in brown algae and 156.0-530.4ppm (average: 248.2ppm) in red algae. Especially, that of Iron in green algae showed higher value than in any other. 7) The content of Manganese were in the range of 48-221ppm (average: 157.25ppm) in green algae, 12-65ppm (average: 41ppm) in brown algae and 72-162ppm (average: 121ppm) in red algae. Especially, that of Manganese in brown algae showed lower value than in any other. 8) The content of Zinc were in the range of 191.3-451.1ppm (average: 290.05ppm) in green algae, 89.9-374.2ppm (average: 202.64ppm) in brown algae and 106.4-281.4ppm (average: 188.93ppm) in red algae. 9) The content of Magnesium were in the range of 0.48-1.83% (average: 1.27%) in green algae, 1.04-1.71% (average: 1.21%) in brown algae and 0.42-1.24% (average: 0.097%) in red algae. 10) The content of Fluorine were in the range of 29.2-92.7ppm (average: 53.03ppm) in green algae, 33.3-43.5ppm (average: 39.18ppm) in brown algae and 32.4-59.0ppm (average: 44.84ppm) in red algae.
