Laboratory Findings In Symptomless Clonorchiasis.

The duration of infection, frequency of eating raw fresh water fishes, and a series of liver function tests were studied in a group of 23 Korean symptomless cases with Clonorchis sinensis, and compared with those in a control group of uninfected persons. Of 23 lightly infected cases, 11 cases who had been infected for 10 to 20 years was found the highest in percentage(47.8), and 2 had been infected for over 30 years.

[Studies on the intradermal test of Clonorchis peptide(CPT) Antigen 1. Preliminary report].

Polypeptide antigen as isolated from adult worms of Clonorchis sinensis by means of diluted HCl-extraction method. Preliminary intradermal examination with those polypeptide antigen(CPT) were performed on patients of clonorchiasis, paragonimiasis and metagonimiasis and the result of the intradermal test with CPT antigen were compared with those of Clonorchis protein fraction(CPF) and Veronal buffer saline extraction (VBS) antigen. The result of the examination were summerized as follows: 1.
