This study was undertaken to investigate the toxic effect of AF-2, 2-(2-furyl)-3-(5-nitro-2-furyl) acrylamide, in the diet of rats (Splague Dowley) for 4 weeks. Comparisons were made of weight gains, organ weights and the cholesterol, phospholipid and triglyceride content of the blood serum and liver tissue. Rats were divided into three groups, a control group which was fed on a standard diet and two groups were fed with 0.04% (group I) and 0.2% (group II) of AF-2. Male rats weighing 370-410 g, female rats weighing 240-250 g were used in this experiment and each group was composed of 24 Albino rats. The results were as follows. 1. Comparisons of weight gains, control and experimental groups did not show significant differences. 2. An examination of organ weights, liver weights of experimental groups showed higher than that of the control group. 3. In the lipid content of blood serum, phospholipid contents of experimental groups were lower than that of the control, while cholesterol and triglyceride content of experimental groups were higher than that of the control. 4. In the lipid content of liver tissue, phospholipid and triglyceride content of experimental groups did not show considerable changes, but cholesterol content was increased in proportion to AF-2 content. From these results, the authors could observe the significant changes in weight gains of liver and cholesterol content after feeding. It is concluded that the toxic effect of group II showed higher than that of group I and AF-2 had a toxic effect on rat liver to a certain extent.

AF₂를 0%(control), 0.04%(group I), 0.2%(group II) 첨가(添加)한 식이(食餌)를 4주간(週間) 동안 백서(白鼠)에 투여하여 체중(體重)의 변화(變化), 최종기간(最終期間)의 장기중량(臟器重量), 혈청(血淸) 및 간(肝) 조직내(組織內) 지질구성(脂質構成) 중(中) cholesterol, phospholipid, triglyceride를 정량비교(定量比較) 관찰(觀察)하여 다음과 같은 결론(結論)을 얻었다. 1. 체중변화(體重變化) : 대조군(對照群)과 I, II 군(群)의 체중변화(體重變化)에서는 거의 차이(差異)가 없었다. 2. 장기중량(臟器重量) : 장기(臟器) 중(中) 간(肝) 중량(重量)만이 대조군(對照群)에 비(比)해 I, II 군(群)이 모두 높았으며, 비(脾), 심(心), 신(腎), 등(等)은 유의(有意)한 차(差)가 없었다. 3. 혈청내(血淸內) 지질(脂質) 변화(變化) : 대조군(對照群)에 비(比)해 I, II 군(群)의 phospholipid 함량(含量)은 낮아지고, cholesterol, triglyceride 함량(含量)은 I, II 군(群)이 비례적(比例的)으로 높아지는 경향(傾向)을 보였다. 4. 간(肝) 조직내(組織內) 지질(脂質) 변화(變化) : 대조군(對照群)에 비(比)해 I, II 군(群)의 phospholipid, triglyceride, 함량(含量)은 변화(變化)가 없으나, cholesterol 함량(含量)만이 I, II 군(群)이 비례적(比例的)으로 높아졌다. 이상(以上)의 결과(結果)로써 AF₂가 백서(白鼠)의 간(肝) 중량(重量) 및 cholesterol 함량(含量)에 유의(有意)할 만한 변화(變化)를 일으킴을 발견(發見)할 수 있으며, II 군(群)이 I 군(群)에 비(比)하여 현저(顯著)하게 높음을 알 수 있는 것으로 미루어 보아 최소한(最小限) 간(肝)에 독성(毒性)으로 작용(作用)한다고 생각(生覺)된다.
