카드미움이 누에 생리에 미치는 영향 II. 누에 혈액의 Protein 합량과 GOT 및 GPT 활성의 변화에 대하여

Studies on the Effect of Cajmium on the Physiology of Silkworm, Bombyx mori L. II. With Reference to the Change of Total Proteins and Activities of GOT and GPT in Haemolymph of Fifth Instar Silkworm Larvae

카드미움을 누에에 투여하여 발육경과에 따른 암수간의 누에 혈액단백질의 변화 및 GOT, GPT활성을 조사하였다. 얻어진 결과를 요약하면 다음과 같다. 1. 카드미움처리구는 무처리구에 비해 총혈액단백질 함량이 낮았다. 한편 카드미움처리에 의한 암수간의 총단백질함량의 변화에 있어서는 숫컷이 더 큰 영향을 받고 있어Te. 2. 발율경과에 따른 Albumin함량은 암컷에 있어서는 카드미움의 영향이 적은데 반해 수컷에 있어서는 무처리에 비해 약 7% 감소하였다. 그러나. Globulin은 암컷 숫컷 모드 카드미움의 영향이 컸다. 3. GPT 및 GOT의 활성은 카드미움에 의해 다같이 저해되었다.

The just molted larvae of the fifth instar were fed on with cadmium trated mulberry leaf and on the third day of the fifth instar the daily change of the total protein, activities of GOT and GPT in larvae haemoymph were sexually analyzed. The result obtained are summarized as follows : 1. The total haemolymph was decreased by cadmium treatment. A decreasing ratio of the total haemolymph protein was higher at the later development stage of the male fifth instar than the female fifth instar. 2. There seemed a slight difference in albumin content of the female blood along with the fifth larvae development between control and cadmium treatment where 7% decrease of blood albumin took place with cadmium treatment comparing to that of cotrol. Contrarily a decrease of blood globulin was made on both sexes. 3. The activities of GOT and GPT were inhibited by cadmium treatment.
