Aflatoxin B₁,메주및 고추기름에 의한 Wistar쥐의 胃癌發生에 관한 硏究

朴貴善 東亞大學校附設基礎科學硏究所 1984 基礎科學硏究論文集 Vol.1 No.1

Rate를 대상으로 Aflatoxin B₁,메주,고추기름을 투여하여 다음과 같은 실험 성적을 얻었다. 1.실험동물의 생존률은 메주,고추기름 혼합투여군이 대조군에 비해 약 20% 감소하였 으며,소량 투여군에 비해 대량 투여군이 생존률이 낮았다. 2. 실험동물의 체중 변화는 대조군에 비하여 투여군이 체중감소를 나타내었고 대량 투여군과 소량 투여군 사이에는 유의적인 차이가 없었다. 3. 실험동물의 식이 섭취량은 대조 군에 비하여 투여군이 낮았으며,식이 효율은 오히려 투여군이 증가하는 경향을 나타내었다. 4.위점막에 대한 조직학적 검사 소견은 실험군 모두 위암 발생이 나타나지 않았다. Aflatoxin has been known as a strong hepatocarcinogen in experimental animals and possibly in human. And it has been known to have potential effect on gastric cancer. According to recent domestic studies about 10% of maejoo contain aflatoxin. Red pepper has been used for red pepper taste, kimchi, and other meals as most important condiments. The experimental study was performed in 182 wistar rats for 29 weeks. They were devided into 7 groups; Af B₁, P₁, P₂, M₁, M₂, P₁M₁, and P₂M₂. Group P₁, P₂was treated 1%, 3% red pepper oil and aflatoxin B₁, as a large dose group. Group M₁, M₂ was supplemented 5%, 10% maejoo and aflatoxin B₁. Group P₁M₁, P₂M₂ was given 1%, 3% red pepper oil, 5%, 10% maejoo and aflatoxin B₁. Aflatoxin B₁(10㎍ per day in Dimethy Sulfoxide) was injected big oral intubation 50 times. The results of this study were summerized as following. 1. The final survival rate at 29th week of the rats treated with maejoo were lower than red pepper treated group significantly. And the maejoo and red pepper large dose group showed the lowest survival rate. 2. The food intake of red pepper large does group was lowest in all experimental group significantly. And the food intake of large dose groups were lower than small dose group. 3. The body weight gain of red pepper and maejoo treated groups(P₁M₁,P₂M₂) had lowest body weight gain at 29th week. 4. The upper gastro intestinal cancers did not appeared in all experimental groups.

This study was conducted to investigate the relationship of serum calcium and magnesium levels to depression and anxiety symptoms in 80 homemakers. Fasting blood samples were collected and serum calcium and magnesium concentrations were measured. At the same time psychological conditions of subjects were estimated by STAI-S(State Trait Anxiety Inventory-State) questionnaire. Resulting from psychological test, number of high score group(HSG) were higher than those of low score group(LSG) and 85% of subject in 32-38's were belonged to HSG. Mean serum concentrations of calcium and magnesium in HSG were significantly lower than those in LSG. Almost low calcium and magnesium levels of subjects appealed to depression and anxiety symptoms. Depression and anxiety scores in subjects who have been calcium supplementation were significantly lower than those in before calcium supplementation. After calcium supplementation in HSG, depression and anxiety scores were significantly decreased and serum calcium and magnesium levels were significantly increased to normal ranges. This results suggested that psychological conditions of homemaker might be affected by serum calcium and magnesium levels.

Every manager considers some kind of forecast in every decision. Some of these forecasts are quite simple. Ather forecasts are much more complex. These are three basic kinds of forecasts: judgemental forecasts, extensions of past history (Time series methods), and causal forecasting models. If considerable historical data are available and if we know the relationship between the variable we want to forecast and other variables that we can observe, it is possible to construct a causal forecast, One causal model, regression, can be used to relate sales to a number of other environmental factors including the level of GNP, the price level, disposable income, unemployment and population shifts, Causal models tend to consider a great deal of information: consequently they are among the most extensive forecasting tools to use. We shall deal with complex problems that will reguire larger samples and additional independent variables. To assist in solving these more detailed problems, we make use of a computor, which allows them to perform a large number of computations in a very small period of time.

This study was to investigate 1) the correlation of serum Ca, with depression and anxiety; and 2) the effect of Ca intake on those symptoms. The subjects were three females and two males who were 53-66 years old with the severe subjective symptoms of depression and anxiety. They have taken more than twice Ca of RDA(recommended dietary allowances for Koreans) daily for 6 months(dietary treatment). The prestudy Ca intake of the subjects was low: 60% of RDA for Koreans. Their serum Ca concentration was also low: 6.67±0.15mg/dl before the dietary treatment. They expressed severe depression and anxiety, with high self scores in a psychological test. Their serum Ca concentration increased to 8.32±0.17mg/dl after six months of dietary treatment, while the symptoms of depression and anxiety decreased significantly after two months and nearly disappeared after six months. This result seemed to be an effect of the dietary high Ca intake. Serum Ca and the psychological states of depression and anxiety correlated negatively, and the coefficients of determination were high in the results of linear regression analysis of depression and anxiety by serum Ca. Therefore the serum Ca concentration could be a good marker to predict depression or anxiety relatively well. The continuous high Ca intake could decrease the probability of developing depression or anxiety and mitigate their symptoms because serum Ca concentration increased, while the state of depression and anxiety decreased with the increased Ca intake.
