Direct contact method of autoradiography was utilized in studying the distribution of exogenous C(14)-proline in Clonorchis sinensis, Eurytrema pancreaticum, Hymenolepis diminuta and Dipylidium caninum. The most distinct autoradiogram were obtained after 60 min of incubation, corresponding to the maximal absorption of C(14)-proline in these parasite. The radioactivitity of this labeled amino acid was chiefly concentrated in reproductive organs, especially egg-containing uterine tubules.

In order to understand the tissue responses of albino rat host against Paragonimus iloktsuenensis infection, the histopathological changes of the spleen and the lungs in 6 experimental groups of rats were observed in relation with the growth, maturation and migration of this lung fluke. Rats of the experimental groups, each group consisted of 5 rats, were infected with the metacercariae of P. iloktsuenensis which were isolated from brackish water crab, Sesarma dehaani, and were kept for 3 days, 3 weeks, 4 weeks, 7 weeks, 10 weeks and 14 weeks of infection period. Peripheral blood smear slides for the differential leukocyte count were prepared and also worm collection was completed immediately after the infection period. Paraffin sections of the spleen and the lung tissue were stained with hematoxylin-eosin and methyl-green-pyronin (MGP) stain. Those materials from the experimental groups were examined in comparison with the materials obtained from control group, with special reference to immunologic aspects of host response. The results obtained were as follows: The counts of large pyroninophilic cell (LPC) in the periarterial sheath of spleen were rapidly increased in earlier period of infection, and those of peribronchial lymphatic tissue started to increase after the penetration of lungfluke into the lungs. The LPC counts of both the spleen and the lungs were on the decrease in conjunction with the necrosis of the lung fluke in 14th week of infection. On observing differential leukocyte count of peripheral blood smear, the fluctuation of lymphocyte count was proportional to that of LPC count, and the lymphocyte count was consistently higher than that of normal rats. On the other hand, neutrophil count of experimental group showed reciprocal relation to the LPC counts. The nature and characteristics of pulmonary lesion produced by the P. iloktsuenensis were just the same as those produced by P. westermani. The lesions were represented by thick and fibrosclerotic cavern, granuloma due to eggs, pneumonic process and cellular infiltrations.

Radioactive (14)C-glucose(U) was given to Clonorchis sinensis in Tris buffer medium, in corder to trace the metabolic fate of the labelled carbon. The labelled carbon from glucose enters into intermediary metabolites and end products of anaeroblic glycolysis, Embden-Meyerhof pathway, and of aerobic Krebs cycle. These product were identified by one or two-dimensional paper chromatography in combination with autoradoigraphy. The labelled metabolites detected in this experiment corresponded to pyruvic acid, latic acid, malic acid, succinic acid and fumaric acid. Amino acids, such as alanine, aspartic acid, glutamic acid, valine, theronine, and serine, derived by the degradation of (14)C- glycose were also found. Labelled compounds behaving like alanine, aspartic acid and glutamic acid were observed in the chroma to gram of incubation medium. The preciptation which suggests a positive reaction for protein occured when absolute ethanol was added to the incubation medium.

The results of this study which had been investigated for the purpose of analyzing heavy metal concentrations in women's blood and urine, their correlation degree and significance of cadmium as indicator of accumulated heavy metals are as follows. 1) In blood, concentrations of Cd, Pb, Cu and Zn are respectively 0.0110+/-0.14 ug/ml, 0.208+/-138 ug/ml, 0.899+/-0.153 ug/ml and 5.432+/-1.020 ug/ml. 2) In urine, concentrations of Cd, Pb, Cu and Zn are respectively 0.003+/-0.12 ug/ml, 0.025+/-0.18 ug/ml, 0.013+/-0.12 ug/ml and 0.277+/-0.192 ug/ml. 3) Correlation coefficients between blood and urine are only significant in Zn (r=0.363, p<0.01). 4) In blood, correlation coefficients of Cd concentration and Pb, Zn are respectively 0.518 (p<0.01). 5) Correlation coefficients between Cd concentration in blood and Pb, Cu and Zn in urine are respectively r=-0.012, r=0.027, r=0.241 (p<0.05), and only Cd concentration and Zn is significant.

PURPOSE: To verify the association between cigarette smoking and bladder cancer in the Korean population, as smoking is well known as a risk factor on bladder cancer. The risk of bladder cancer was compared among never-smokers, ex-smokers and current-smokers using a multivariate adjusted incidence rate and the mortality rate of bladder cancer of Koreans. MATERIALS AND METHODS: A total of 348,010 participants were enrolled in this prospective study between 1993 (to 1994) and 2002. All participants completed a self administered questionnaire on cancer risk factors, including smoking habit. Follow up for incident bladder cancer was established. We classified all participants into three categories: current-smoker, ex-smoker and never-smoker, on the basis of their smoking habits. We confirmed bladder cancer from the data of the Korea National Cancer Registry and National Health Insurance Corporation up to (December?) 2002. The multivariate adjusted incidence and the mortality due to bladder cancer were used for both genders for a statistical analysis using a Cox proportional hazards model. RESULTS: The incidence rate of bladder cancer per 100,000 persons in male never-smokers, ex-smokers and current-smokers were 27, 41 and 48, respectively, and the multivariate adjusted relative risks (RR) were 1.3 (95% confidence interval (CI), 0.9-2.0) and 1.7 (95% CI, 1.2-2.3) in ex- and current smokers, respectively. The incidence rate of bladder cancer in women was 4.7, 8.4 and 13, respectively. There was no significant association between the risk of bladder cancer and the amount and duration of smoking. CONCLUSIONS: We concluded that current smokers have an increased incidence and mortality rate of bladder cancer in both genders in the Korean population, but there was no significant difference in relation to the amount and duration of smoking.

When a soft tissue mass in the bony wall of the paranasal sinus is present, it is difficult to make a distinction between tumor and inflammatory mass on CT. Fungal sinusitis may have soft tissue attenuation on the bony wall of the sinus, bony sclerosis, focal bony destruction, and calcific area on CT. This is a report of four proven cases of fungal sinusitis, asperogillosis in 3 cases and mucormycosis in 1 case, All 4 patients had CT and one patient had MRI, On CT, bony sclerosis and destruction were well visualized in all cases. On MRI, mycetoma in the maxillary sinus was hypointense on T1 weighted images and more hypointense on T2 weighted images. Although CT appears to be the best modality for initial examination of the patient with sinusitis, the differentiation of fungal sinusitis from tumor mass or other entity may be better accomplished with MRI.

The antiphospholipid antibodies are characterized by prolonged phospholipid-dependent coagulation test (known as APTT or Russel viper venom), thrombosis, thrombocytopenia, and fetal loss. The association of antiphospholipid antibodies with one or more of these characteristic clinical features has been termed the i antiphospholipid syndrome. We have experienced a case of successful live birth after treated a woman with heparin and aspirin who has experienced spontaneous abortion four times with antiphospholipid antibodies and present it with the review of literature.
