The fowl nematode Ascaridia galli employed in this experiment was obtained from the intestine of domestic fowls at the local market. The worms selected and washed several times in normal sterilized saline solution. Each about thirty of intact worms were incubated in 50 cc volume of special incubation flasks with incubation mixture consisting of 10 cc of Krebs-Ringer phosphate buffer (pH 7.4) to which were added universally labeled C14-glucose and non-radioactive carrier glucose so as to contain concentration of 200 mg per cent. The worms were allowed to incubation for 3 hours in Dubnoff metabolic shaking incubator at 38 C. After incubation period, respiratory CO(2) samples from central well of incubation flask were analysed for total CO(2) production rate and their specific activity of respiratory CO(2). Glycogen samples isolated from worms were analysed for uptake rate was determined by analyzing the difference of the glucose concentration in a medium before and after incubation period . Radioactivities of these series of experiments were counted by an endwindow Geiger-Muller counter as an infinitely thin samples. The quantitative analysis of C(14)-glucose utilized by Ascaridia galli was summarized as the following . The glucose uptake rate by A. galli was a mean value of 1.73+/-0.32 micro-mole per hour per gram of wet wt. and total CO(2) production rate by the worms averaged 8.44+/-1.11 micro-mole per hour per gram of wet wt. The relative specific activity of respiratory CO(2) (R.S.A CO(2)) averaged 2.68+/-0.38 per cent . Thus , a man of 2.68 per cent of total CO(2) production rate was originated from the glucose in the medium, therefore the rate of CO(2) production derived from medium glucose was a mean of 0.23+/-0.03 micro-mole per hour per gram of wet wt. Thus, the average value of 2.58+/-0.55 percent (R.G.D CO(2))of glucose utilized by the worms from the medium glucose was oxidized to respiratory CO2. The tissue concentration of glycogen in A. galli was a mean of 22.59+/-1.18 miligram per gram of wet wt or 2.26+/-0.123 percent per gram, and the turnover rate of glycogen pool yielded with a mean of 0.17+/-0.04 percent per hour or 0.037+/-0.006 miligram per hour per gram of wet wt. Therefore, a mean value of 16.37+/-4.04 per cent (R.G.D gly) of glucose was incorporated to the glycogen. These data account for that at least 18.95 per cent of the utilized glucose by the worms participated in furnishing the oxidation into respiratory CO(2) and the synthetic process into glycogen. According to the above data of the experiment, it is suggested in the metabolic process of glucose by Ascaridia galli that the synthetic process into the glycogen is more active than the oxidative process into the respiratory CO(2).

This study was undertaken to evaluate the status of human paragonimiasis in Kang Hwa Gun, Kyunggi Do, Korea from March 1973 to October 1975 by the use of intradermal screening test with Veronal buffered saline antigen. A total number of 7,352 (male 3,936; female 3,4l6) consisting of 3,447 primary school children, 2,689 middle school students, l,008 high school students of 9 Myuns out of 13 Myuns of this County and 208 residents of all age group in Kilgeong-Ri, Yangdo Myun were examined by the intradermal test with Paragonimus antigen. In order to detect Paragonimus egg, the sputum and the stool examinations were undertaken on the residents in Kilgeong-Ri. The infestation rate of crayfish with Paragonimus metacercaria was also examined in Konneung and Jeongha village in Kilgeong-Ri. The following results were obtained in this survey: As a whole, 16.6 per cent of the examiners showed positive reaction with sexual difference of 16.1% in male and 14.8 per cent in female. In age groups, the highest positive rate showed in middle school age group (17.1 per cent) than primary school (14.0 per cent) and high school age group (11.4 per cent). In regional differences of positive rates, the highest rate (28.4 per cent) showed at Yangdo Myun followed by Kilsang Myun (27.0 per cent), Hwado Myun (25.0 per cent), and Naega Myun(20.8 per cent). In the result of 208 residents Kilgeong-Ri, the positive of 36.1 per cent in male and 20.2 per cent in female. The highest positive rate showed in 10 to 19 age group (41.5 per cent). Among the residents in Kilgeong-Ri, Paragonimus eggs were detected in 11 residents by the sputum and the stool examinations. The infestation rate of crayfsh with Paragonimus metacercariae was 100 per cent (41 out of 41 crayfishes) in Konneung village, and 84.6 per cent (9 out of 13 crayfishes) in Jeongha village, Kilgeong-Ri The fluctuation of the infection rate of crayfish with Paragonimus metacercariae was decreased in Konneung village in 2 years after the treatment with Bilevon against 10 paragonimiasis patients.

In order to find a highly efficient compound against Clonorchis infection, the anthelmintic activity of disophenol, Tremerad (SYD-230), dithiazanine iodide, dehydroemetine-late-release tablets(RO 1-9334/20), niridazole (Ambilhar), hexachlorophene (G-11), Hetol(1, 4-bis-trichloromethylbenzol) and Bilevon (niclofolan) was tested against Clonorchis sinensis experimentally infected rabbits. All drugs showed a progressive increase in efficacy as the dose rate. They were highly efficient against Clonorchis infection if sufficiently high, potentially toxic doses were given. The efficacy was evaluated by the number of detected worms with vital condition at autopsy after the treatment with above drugs. The high efficacy was observed at the following dose rates of each drugs, i.e. disophenol at a single dose of 30 mg/kg, Tremerad at the daily dose of 200 mg/kg for 10 consecutive days, dithiazanine iodide at the daily dose of 50 mg/kg for 6 consecutive days, dehydroemetine at the daily dose of 10 mg/kg for 10 consecutive days, hexachlorophene at the daily dose of 20 mg/kg for 10 to 15 consecutive days, Hetol at the daily doses from 50 to 100 mg/kg for 5 to 10 consecutive days, and Bilevon at a single dose of 8 mg/kg. Moderate effectiveness was shown in niridazole at the dose of 25 mg/kg for 10 days medication. The use of these anthelmintics for the clinical treatment of Clonorchis sinensis infection is discussed.

Scabies may be seen in psoriatic patients, although not frequent. This situation provokes many problems including the difficulty of diagnosis and uncertainty of appropriate therapy. We report a case of a young female with an existing psoriasis aggravated following scabetic infestation. At first, she took an antiscabetic treatment but the severity of psoriasis persisted. Subsequently, cyclosporine treatment was started and the psoriatic lesions improved deamatically.

Dermal melanocytosis is characterized by the presence of ectopic melanocytes in the dermis and shows several morphological forms, including the mongolian spot, the blue nevus, the nevus of Ota, the nevus of Ito, and dermal melanocyte hamartoma. A 30-month-old boy had a gray blue patch on the left deltoid region, upper back, sacral area, the entire length of the right arm, and right hand. There was a bluish speckled patch on the right palm. The lesions were present at birth, and no appreciable change in appearance had occurred. He also had blue to brownish pigmentation on the right side of his face with dark bluish pigmentation of the right sclera. His Mental and physical development had been normal. The histopathological examination revealed dendritic dermal melanocytes, mainly in the upper and mid dermis. Clinically and pathologically, the patient was diagnosed as having Ota nevus, Ito nevus, mongolian spot, and dermal melanocyte hamartoma. To our knowledge, dermal melanocytosis with 4 different morphological forms in a patient has not previously been reported. We report this unique case of dermal melanocytosis with various morphological forms.

BACKGROUND: Complete clearance of the lesions by using calcipotriol alone have not been re-ported commonly in the treatment of psoriatic patients. Moreover, lesional and perilesional irritation are reported in some patients using calcipotriol, which may result in premature termination of the treatment due to impairing the compliance. OBJECTIVE: A clinical study was conducted to determine whether, in the topical treatment of psoriasis, a combination of calcipotriol cream and methylprednisolone aceponate was more effective than calcipotriol monotherapy. METHODS: Twenty-one psoriasis patients who had the symmetric lesions on the right and left lower legs were enrolled in the study. A combination of calcipotriol cream and methylprednisolone aceponate therapy was done on the left lower legs, whereas calcipotriol alone was applied on the right lower legs twice daily. PASI score and adverse events were recorded at each visit (1, 2, 3, 4, 6 week). The overall therapeutic result was also assessed by the physician and patients. RESULTS: The initial PASI score was 7.09 on both legs. After 6 weeks, the mean PASI score was 3.85 on the left leg, and 5.70 on the right leg (p<0.05). In the physicianOs global assessment, the percentage of patients who showed the improvement of more than half of lesions was 29% in the monotherapy and 62% in the combination therapy area. Two patients complained of mild itching sense on monotherapy, but there was no specific side effect on combination area. CONCLUSION: The combination therapy was more effective, as assessed by all evaluated variables. Furthermore, this combination reduces the adverse effects caused by long-term use of topical corticosterois as well as the irritation associated with. calcipotriol.

The adult worm and plerocercoid larva(sparganum) of Diphyllobothrium mansoni and Moniezia expansa employed in this experiment. The adult worms were divided into three portions, i.e. immature, mature and gravid proglottids, and each proglottids were incubated in 50 cc or 250 cc volume of special incubation flasks with incubation medium consisting of 10 cc of 25 cc of Krebs-Ringer phosphate buffer (pH 7.4). The incubation medium was added C(14)-acetate and non-radioactive carrier Na-acetate so as to contain acetate concentration of 50 mg per cent. The worms were allowed to incubate for 5 hours in the Dubnoff metabolic shaking incubator at 38 C. After incubation period, the lactate and pyruvate appearance rate, total CO(2) production tate, the turnover rates were employed as pervious report(Seo et al., 1965). The quantitative analysis of C(14)-acetate utilized by the adult worm and plerocercoid larva of D. mansoni and M. expansa were compared and discussed in this report. According to these data of the experiment, it is impressed that the fatty acid such as acetate may play a role of major part of their metabolism in the adult worm and plerocercoid larva of D. mansoni , whereas minor part of acetate participated in the metabolism by M. expansa.

The adult worms of cestodes, Moniezia expansa and Diphyllobothrium mansoni employed in this experiment. The worms were divided into three portions, i.e. immature , mature and gravid proglottids, and each proglottids were incubated in a certain incubation period, and the glucose uptake rate, total CO2 production rate, tissue concentration and their radioactivities were employed as previous reports(Rim et al., 1965). The glucose uptake rate by M. expansa was a mean value of 6.46+/-1.23 micromole per hour per gram of wet wt. and the rate by D. mansoni was a mean value of 18.8+/-0.8 micro-mole per hour per gram of wet wt. The higher rates were observed in the mature proglottid of M. expansa and in the immature proglottid of D. mansoni . The total CO(2) production rates by the worms averaged 14.0+/-2.37 micro-mole per hour per gram in M. expansa and 17.51+/-1.54 micro-mole per hour per gram of wet wt. The relative specific activities of respiratory CO(2)(R.S.A CO(2)) averaged 22.2+/-5.15 percent in M. expansa and 54.2+/-2.2 per cent in D. mansoni. In the both worms, the higher values were obtained in the mature proglottids. Therefore, the average value of 8.84+/-2.66 per cent of glucose utilized by M. expansa and 8.23+/-0.50 percent of glucose utilized by D. mansoni from the medium glucose was oxidized into respiratory CO(2). The tissue concentrations of glycogen were a mean of 2.21+/-0.46 percent per gram of wet wt. in M. expansa and 7.56+/-1.24 percent per gram of wet wt. in D. mansoni. The higher concentration of glycogen was observed in the gravid proglottids of M. expansa, however the gravid proglottids of D. mansoni showed lower concentration of glycogen than the other proglottids. The turnover rate of glycogen pool yielded with a mean of 0.04+/-0.01 miligram per hour per gram of wet wt. of M. expansa, whereas a mean of 1.66+/- 0.46 miligram per hour per gram wet wt. of D. mansoni. Therefore, a mean value of 2.58+/-0.93 per cent(R.G.D gly) of glucose utilized by M. expansa and 53.6+/-1.4 percent by D. mansoni was incorproated into the glycogen . These data account for that at least 11.42 per cent of the utilized glucose by M. expansa and 61.83 per cent of the utilized glucose by D. mansoni participated in furnishing the oxidation into respiratory CO2 and the synthetic process into glycogen.
