Abstract

The mineral contents of the adult Clonorchis sinensis from rabbits and human were measured, and its qualitative and semi-quantitative analyses were studied with 3.4 meter Ebert-Grating spectrograph, and its quantitative analyses were studied with Beckman DU spectrophotometer.

The adult Clonorchis sinensis used in this study were divided into two groups, the first group was collected from the bile passage of the man (C. sinensis from man), the second group was collected from the bile passage of the rabbit(C. sinensis from rabbit).

Simultaneously, spectrographic and photometric analyses were also performed on the adult worms of Paragonimus westermani.

Furthermore, comparative spectrographic analyses of the trace elements were carried out on the C. sinensis from man, C. sinensis from rabbit, Fasciola hepatica, Eurytrema pancreaticum, and Paragonimus westermani, and the approximate contents of the trace elements of the above trematodes were compared with that of their host tissues and biles. The results obtained were as follows:

1. In the spectrographic analyses of C. sinensis from man, sodium, phosphorus, potassium, copper, calcium, aluminum, iron, and magnesium were detected predominantly, and zinc, titanium, silicone, lead, manganese, barium, cromium, molybdenum, and silver were detected as trace elements.

2. In the differences of level of the minerals in these two C. sinensis, copper level of C. sinensis from man was higher than that of C. sinensis from rabbit, while calcium level of the former worm was higher than that of the latter worm. The trace level of lead, molybdenum, and silver were acertained in the former, but latter were not detected.

3. The contents of the minerals showed the characteristic features in each trematodes: the mineral of flukes in each host were much more than that of the others; such as copper in C. sinensis from man, calcium in the C. sinensis from rabbit, and silicone in the P. westermani. The vanadium was detected in the F. hepatica, E. pancreaticum, and P. westermani, while the other flukes were not detected.

4. In the comparative spectrographic analyses of the trace elements among the trematodes and their host tissues and biles, the minerals which detected from flukes were also found in their tissues and biles of their host. But the mineral levels of C. sinensis from man, F. hepatica, E. pancreaticum, and P. westermani were higher than that of their host tissues and biles, except the C. sinensis from rabbit.
