Authors carried out the experimental study to investigate whether the Paragonimus westermani would uptake the blood in the parasitic definitive host, and also tried for the amount and distribution of the blood which would be harbored in a worm body, and so on. Experimental animals used in this study were dogs and cats, and they were infected with metacercariae of P. westermani. Several months later of the infection, Cr(51) tagged red blood cells were administered to each animal, and the animals were sacrificed and autopsy was done after 24 or 48 hrs of the administration. One part of the detected P. westermani adult worms of each animal were bred in Tyrode's solution and the others were killed by fixing in formalin solution. By Well-type scintillation counter, the radioactivities were measured for the alive and killed worms and of the blood of each experimental animal which was collected at autopsy . In conclusion, it was found that P. westermani worms uptake blood in parasitic definitive host, and amount of the blood harboring in a worm of 56 infection-days(size of worm; 4 x 3 x 1 mm) was 0.002 ml, 0.004 or 0.005 ml in 103 infection-days(size of worm: 8 x 5 x 3 mm) and 0.011 ml in 217 infection-days(size of worm: 9 x 7 x 4 mm). Almost of the whole blood uptaked in the worms was distributed in intestine. It was observed that the blood uptaked in the worm body was excreted continuously through the excretory pore, so that the radioactivity could not measured almost completely in cases of 24 hrs-breeding worms.

Authors carried out experimental study on chemotherapy with oral administration of Dithiazanine iodide (D.I.) and Bithionol sulfoxide(B.S.) in rabbit clonorchiasis. And the following result was obtained. In change of the E.P.G (eggs per gram feces) by D.I. administration, it was rather increased in early stage of the administration than prior to administration, and thereafter decreased gradually. In the change of the C.S. worm body by D.I. administration, there was not only prominent change of supporting tissue but also the change of reproductive organ was found. In considering the wormicidal effect of D.I. from detecting rate of survival worms, the effect was slight in group of 100 mg(80 mg/kg) per day dosage, but the effects were very excellent and almost complete by proper times of administration in groups of 200 mg (130 mg/kg) per day or higher dosage. But the side effect and intoxication sign of D.I. were appearent in groups of 200 mg or higher dosage. By B.S. administration, E.P.G. was decreased gradually. In changes of the C.S. worm body by B.S. administration, prominent inhibitory chnnge was seen in egg formation ability. Slight wormicidal effect of B.S. was observed in groups of 140 mg (100 mg/kg) per day or higher dosage. Side effect and intoxication sign of B.S. were found little in groups of 140 mg or lesser dosage.

Authors carried out the survey for human paragonimiasis in Ko-Hoong County, Chun-Nam Province, Korea from July to September 1964 by the use of intradermal screening test with Veronal buffered saline antigen. Eight myuns (village) out of 13 myuns of this county were selected for the survey, regarding balanced selection. The number of 2,916 primary school children of high class and 764 residents of all age groups in these areas were examined (total 3,680; male 1,961; female 1,719). The following results were obtained in this survey. As a whole, 20.1 per cent of the examiners showed positive reaction, with sexual difference of 20.9 per cent in male and 19.1 per cent in female. In regional differences of positive rate, the highest rate(50.1 per cent) was showed at Po-Doo myun and lowest rate(3.6 per cent) was showed at Do-Yang myun. In age group, the highest positive rate was showed in 16 to 20 age group (46.7 per cent). In regional comparison of paragonimiasis infectivity of whole nation (province and county), Ko-Hoong County as nearly same as the Hea-Nam County, Chun-Nam Province follows next of Cheju Province, the highest prevalance area of paragonimiasis in Korea, in concentration of prevalence of paragonimiasis.

The question of infectivity and prevalence of Clonorchis sinensis in Cheju province (Quelpart Island) was arisen to authors since the several surveys on the endemic diseases were performed in this island. Therefore, authors decided to solute this question. Then the survey on the possible second intermediate host of Clonorchis sinensis was performed and reported already with negative finding. At present time, authors carried out the collection of all kinds of fresh-water snails through all areas of this island, to confirm the presence or not of Parafossarulus manchouricus, the only first intermediate host of Clonorchis sinensis in Korea . And the following results were obtained. The fresh-water snails collected in the survey were Semisulcospira libertina Gould and Lymnaea ollula Gould. Parafossarulus manchouricus Bourguigant was not collected in this island. It is confirmed that the Clonorchis sinensis can not be prevalent in this island.

Eosinophilia is a common finding in premature babies during the neonatal period. Serial eosinophil counts were determined in 94 hospitalized, appropriately grown premature in fants whose gestational ages ranged form 28 to 36 weeks. The incidence, severity and etiologic factors of eosinophilia were retrospectively studied in premature infants, who were divided into three groups according to their gestational age. The results were as follows: 1) Absolute eosinophilia (>700/mm3)was documented in 46.8%(44/94). 2) The duration of TRN and antibiotics was cignificantly higher in infants with eosinophilia than withour eosinophilia (p<0.05). The gestational age of the infants with eosinophilia was significantly shorter than that of the infants without eosinophilia (p<0.05). The infants with eosinophilia started with bottle feeding significantly earlier than the infants without eosinophilia (p<0.05). 3) The infants younger than 30 weeks of gestational age have greater incidence of eosinophilia (75%) than the infant with the gestational age between 34 and 36 weeks (34.3%)(p<0.05). 4) The incidence of mild eosinophilia was higher in the group with gewtational age 30 weeks or below(37.5%)than in the group with gestational age between 34 and 36 weeks(17.1%)(p<0.05).Also, the incidence of severe eosinophilia was significantly higher in the group with gestational age 30 weeks or below(37.5%)than in the group with gestational age between 34 and 36 weeks(17.1%)(p<0.05). 5) Eosinophilia was more prevalent in the infants who received parenteral nutrition composed of glucose, amino acid and lipid(77.8%) than the infants who received only glucose(34.1%)(p<0.05). 6) Gestational age and birth weight were significantly lower in infants with severe eosinopilia than those of mild or moderate eosinophilia. The duration of TRN and antibiotics were significantly longer in infants with severe eosinophilia than those of mild or moderate eosinophilia (p<0.05). 7) The peak eosinophil count was observed significantly later in severe eosinophilic group (26.5 13.1 days)than in non-eosinophilic group(14.4 9.0 days)(p<0.05). The above results suggest that eosinophilia in premature infants may be the effecto of immature immunologic responses to the intravenous administration of extemal antigens like amino acid, lipid and antibiotics.

Pheochromocytomas can arise wherever chromaffin cells are found, and most of them(90%) are in one or both adrenal glands. But they may be located anywhere along the sympathetic chain and rarely in aberrant sites. One of the common extra-adrenal sites from which these tumors can arise is a collection of para-aortic and para-ganglion cells around the origin of the inferior mesenteric artery. We experienced a case of extra-adrenal pheochromocytoma located at the organ of Zukerkandl in a 21-year-old female patient with abdominal colic and paroxysmal hypertension, whose symptoms and blood pressure returned to normal after successful surgical excision of the tumor.

BACKGROUND: Recently, many countries including Korea have been trying to enforce and reform their primary care system. The Family Doctor Registration Program(FDRP) which Korean government had tried and failed in 1996 continuously has been being highlighted because of it's importance. Several private family practitioners started grass root movement for conducting FDRP voluntarily. This survey aimed to know the willingness for private family practitioners to participate in voluntary FDRP and it's major services. METHODS: By mailing, the self administered questionnaires were collected two times during May 20 to June 30 in 1998. The questionnaire contained followings:demographic and practice related factors, willingness to participate FDRP, factors related to it's major services. Subjects were 496 private family physicians who had acquired the certification since 1989. Analyses were made by the Chi square test, t test, and multiple logistic regression analysis. RESULTS: Though overall response rate was only 44.8%(222/496), but age and sex distributions of respondents were similar to those of the total study subjects. The percentage of those having a willingness to participate in voluntary FDRP('Y' group) was 58.6%. The 'Y' group showed phone counselling frequency of 3.2(+/-2.6) times per day. They had much more home visiting experience than 'N' group(62.2% vs 44.9%, P=0.019). After the conduction of FDRP, the frequency of possible night time phone duty per month was 3.5(+/-2.6) times, and the frequency of possible home visiting per week was 1.9(+/-1.4) times in 'Y' group. After multiple logistic regression analysis on the meaningful variables, male(OR=2.25, P=0.0270) rather than female, percentage of child patients<40%(OR=2.526, P=0.0149) rather than that>60%, and having home visiting experience(OR=1.8, P=0.1131) rather than no experience showed relatively higher tendency of participation in voluntary FDRP. CONCLUSION: The results of this survey should be reflected into the health care policy when retrying to implement FDRP in Korea.

BACKGROUND: Heat shock proteins (HSP), especially the HSP 70 family, may play certain roles in the immunophysiology of some skin diseases such as psoriasis, pemphigus, and lichen planus. HSPs generally induce down-regulation of the process of apoptosis that is considered to be one of the acantholysis-producing pathways in pemphigus. OBJECTIVE: We planned to examine possible roles of HSPs 70/105 in the blistering process in pemphigus vulgaris (PV) and pemphigus foliaceus (PF), in connection with the detection results of apoptosis in local tissue specimens. METHODS: Immunohistochemical stainings and Western blot analysis were performed for the detection and semiquantitation of HSPs 70/105 in skin specimens from lesional, nonlesional, and normal control sites. Hoechst 33342 staining was simultaneously carried out to examine features of apoptosis in lesional skin specimens. RESULTS: The findings on expression of HSP were as follows. In PV, the expression of HSP 70 was minimum or negative; however, in PF, the expression was obvious and recognizable in lesional and perilesional normal skin. In contrast, HSP 105 was not detected in all cases of PV and PF. The features of apoptosis were evident at the lesional skin of all cases of pemphigus with acantholytic changes. CONCLUSION: PV and PF had different relative intensities of HSPs in lesional tissue stainings, especially in cases with HSP 70. This suggests that there may be subtle differences in the mechanisms causing acantholysis between PV and PF.

BACKGROUND: A habit of lying-down after eating is known as a risk factor of reflux esophagitis. However the association between gastrointestinal disorders and a postprandial lying-down habit has not yet been identified. Some people believe that lying-down after meals is helpful for their health. We intended to investigate the relationship between such a habit and the health lifestyles, gastrointestinal symptoms, disorders using a questionnaires and gastrofiberscopic results of patients who visited our general health screening center. METHODS: We examined 1,030 subjects (the frequent postprandial lying-down group was 576 persons (57.7%), the rare group was 436 persons (42.3%) who visited our general health screening center for a routine check-up including a gastrofiberoscopy during the period between January 2001 to December 2002. After frequency matching by age and sex, health lifestyles (such as smoking, alcohol consumption, exercise, eating habits, night time sleep duration and awakening frequency, nap, and coffee intake), gastrointestinal symptoms (dyspepsia, epigastric pain, heart burn, chest pain, and constipation) and gastrofiberoscopic findings were compared using results from the questionnaires and gastrofiberscopic findings. Factors such as gastritis and reflux esophagitis were set as dependent variables, while postprandial lying-down was set as an independent variable. The frequent postprandial lying-down group and the rare group were analysed through stepwised multiple logistic regression analysis. RESULTS: Subjects with a frequent postprandial lying- down habit showed a significantly greater degree in alcohol consumption (P=0.010), irregular eating habits (P<0.001), eating between meals (P<0.001), napping (P<0.001), and night time awakening frequency (P= 0.016) than the rare group did. In addition, chest pain (P=0.031) and constipation (P=0.010) were more common in the frequent postprandial lying-down group. However, prevalence of dyspepsia (P=0.147), epigastric pain (P=0.085), and heartburn (P=0.700) showed no differences between the two groups. Being controlled with age, sex, education level, body mass index, and life style factors, postprandial lying-down group showed higher prevalence ratios in erythematous gastritis (OR 1.59; P=0.090), atrophic gastritis (OR 1.71; P= 0.059), and reflux esophagitis (OR 1.78; P=0.103). CONCLUSION: A postprandial lying-down habit is associated with undesirable lifestyles and some gastrointestinal disorders. Therefore, a modification of the postprandial lying-down habit should be recommended. Further investigation is needed to clarify the causal relationships between a postprandial lying down habit and gastrointestinal symptoms and disorders.
