The author studied the β-glucuronidase activity in the urine of 46 males and 19 females with trematodes such as Clonorchis sinensis, Stellantchasmus falcatus, metagonimus yokogawai, paragonimus westermani, Heterophyes heterophyes.
Specific activity of β-glucuronidase was analyzed statistically by sex, age, intensity of infection and mixed infection.
The results obtained in this studies were summarized as follows.
In the 41-50 years of age groups of males, β-glucuronidase activity in the urine was elevated the highest with 1.56U/ml, 1.21U/ml of females and 1.49U/ml of male in the 30-40 years of age groups, but activity of β-glucuronidase in the urine according to age and sex was not statistical significance.
It was gradually increased β-glucuronidase activity in urine of males and females according to number of mixed infection of trematodes species(p<0.01). β-glucuronidase activity in urine of males and females according to intensity of trematodes infection appeared 0.92U/ml in the simple infection, 1.14U/ml in the medium infection and 1.54U/ml in the heavy infection, respectively(p<0.01).
On the basis of results, it was suggested that β-glucuronidase activity in the human urine was significantly increased in the intensity of infection and mixed infection groups than that of normal groups.
, Jong Oh Kim, Sang Hoon Ko The purpose of this study is the evaluate the diagnostic accuracy of MRI, frequent location of injury site and injury type in meniscal injury, retrospective review of false positive cases.
From September 193 to January 1997 in our hospital, we analyzed a hundred cases of meniscal injury suggested by MRI. And we tried to correct operatively in meniscal injury by arthroscopic or open method of operation.
1)Diagnostic accuracy of MRI was 90%
2)Most common site of meniscal injury was medial meniscus posterior horn(54.4%).
3)Most common injury type was Bucket handle tearing(34.4%).
4)Cause of pitfall in false positive case was most common popliteal tendon sheath(30%).
MRI was effective method on diagnosis of meniscus injury and most common injury was medial meniscus posterior horn, And diagnostic fault was caused by popliteal tendon sheath, lateral inferior genicular artery, truncation artifect, meniscofemoral ligament, transverse geniculate ligament.
