  • This study was carried out to compare distribution and isozyme pattern of nonspecific esterase, acid phosphatase and alkaline phosphatase on developing sparganum and adult of Spinometra erinacei by using enzyme-histochemical method and electrophoresis The sparganum and adult were recovered from rats and cat that were infected by sparganum. The results obtained were as follows: Nonspecific esterase had a strong activity in the parenchymal musculature of sparganum and adult, but no detectable level in ihe tegument. A total of 7 and 8 nonspecific esterase bands were detectable in sparganum and adult, respectively. Of these bands, band 3 and 4 were major bands in sparganum and adult. Acid phosphatase had a strong activity in the tegument and the epidermal musculature of sparganum, but no detectable level in the parenchymal musculature. A total of 3 bands were detectable in sparganum and adult. Of these bands, band 3 was major band in sparganum and adult. Alkaline phosphatase had a strong activity in the tegument and the epidennal musculature of sparganum and of adult, but no detectable level in the parenchymal musculature. A total of 2 and 4 bands were detectable in sparganum and adult. Of these bands, band 2 was major band in sparganum and adult. Based on the present results isozyme band patterns showed qualitative and quantitative changes in each tissues of sparganum and of adult during the development.

  • A survey on the infection status of Sparganum and Gnathossoma in frogs was carried out in 11 areas in Gyeongsangnam-do and Cheonlanam-do province, a southern part of Korea. 1. Among 626 frogs examined, 4% were infected with Sparganum, but none with Gnathostoma. The infection rates of Sparganum were variable according to the areas. Those from Kimhae, Sunchon, Jinhae, Sachun, Kosung, Keoje, and Hadong were 16%, 9.1%, 9.1%, 4.1%, 2%, 2%, and 1.5% respectively, but frogs from Hapchun, Kwangju, Namwon and Sanchung were not found infected. 2. Rana nigromaculata was the only species infected with Sparganum. Rana rugesa and Bombing orientalis were not infected. 3. Sparganum was mainly found in the legs and the trunk of frog. About 92.5% of worms were detected in the femoral intermuscular connective tissue. 4. Number per infected frog was in range of one to five, and 2.8% of frogs were inacted by only one worm. 5. The heavier the frog weight, the higher the infection rate of Sparganum. In frogs of 51~60grams, 28.6% were infected.

  • The carbohydrate moieties of larval sparganum proteins in two different species, the snakes, Elaphe rufodorsata, the Balb/c mouse and those of the adult worm, Spirometra erinacei, were compared using five different lectins including GNA, SNA, MAA, PNA and DSA. The GNA positive 53 kDa molecule, which is excretory-secretory protease in the sparganum from the snake showed a stage specific and developmental regulation. We also suggested that sparganum glycosylation may be involved in immune evasion and differentiation into an adult worm.

  • We purified specific 31/36 kDa antigenic molecules from sparganum in different intermediate hosts (snakes and mice) and analyzed their monosaccharide compositions. Compositional analysis showed that glucose and man nose concentrations were 2-3 fold higher in the 31/36 kDa molecule purified from snakes than those from mice. This result implies that antigenic glycoproteins of sparganum from snakes might be modified in mammalian sparganosis with respect to their carbohydrate composition.

  • Spirometru erinocei의 유충인 sparganum에서 추출한 조항원 단백질을 항원으로 하여 sparganosis, cysticercosis, hydatidosis환자의 IgG 항체와 정상인의 IgG 항체를 혈청반응시켜 ELISA와 EITB에 의해 교차반응을 일으키는 비 특이항원 성분과 종특이항원 성분을 추구하였다. 1. sparganum에서 0.01 M PBS (PH 7.4)로 추출한 조항원 단백질을 SDS-PAGE로 전개하여 290 Kd에서 23 Kd범위의 분자량을 가진 25개의 단백질이 분획되었다. 2. sparganum의 조항원을 항원으로하여 ELISA로 sparganosis, cysticercosis, hydatidosis 환자의 190 항체와의 혈청 반응치는 sparganosis환자에게서는 0.44 $\pm$ 0.07에서 1.90 $\pm$ 0.03으로 negative control normal sera의 0.D (0.15 $\pm$ 0.03)를 기준으로 하였을 때 모두 양성이며 민감도(sensitivity)가 100 %이었으며 cysticercosis, hydatidosis환자혈청에서 양성반응이 나타났으며 교차반응도 있었다. 3. EITB에서는 spargancsis환자의 IgG항체에 의해 16개의 항원성분이 인지되었으며 이 중 6개의 항원성분이 정상인의 혈청에서도 인지되어 교차반응을 일으키는 항원성분이었으며 cysticercosis환자혈청에서 인지된 4개의 항원성분 중 2개의 항원성분이 sparganosis 환자혈청에서 인지된 것과 같았으며 hydatidosis환자의 190항체에 의해 인지된 19개의 항원성분 중 12개의 항원성분이 sparganosis환자혈청에서 인지된 항원 성분과 같았다. 4. 290 Kd, 200 Kd, 28 Kd의 항원성분은 sparganosis환자의 196항체에서만 인지되었고 228 Kd, 152 Kd, 66 Kd항원성분은 hydatidosis환자의 19G항체에서만 인지되었으며 66 Kd항원성분은 sparganosis, cysticercosis, hydatidosis, 정상인의 혈청에서 모두 인지되었다. We studied the serological reaction between the specific and nonspecific antigenic components from metacestode (plerocercoid) of spiromeko erimacei and IgG antibodies in sparganosis, cysticercosis. hydatidosis patients and normal human sera by ELISA and EITB. We prepared the crude extracts of sparganlim from snake, Matrix tigrina laterolis and used as antigenic components. By SDS-PAGE, we detected a total 25 peptide bands (fractions) with 290 Kd to 23 Kd molecular weight, and 8 bands of these detected bands developed strongly by silver stain. In serological test, ELISA, we recognized the cross-reaction of antigenic components reacting with IgG antibodies in heterogenous sera, cysticercosis and hydatidosis patients sera. The crude antigenic components of sparganum showed the high sensitivity in sparganosis, hydatidosis patients sera, but showed lower sensitivity in cysticercosis patients sera than the sparasanosis, hydatidosis patients sera. Sixteen antigenic components of these 25 separated bands were recognized by antibodies In sparsanosis patients sera,8 antigenic components in normal human sera, 4 antigenic components in cysticercosis patients sera and 19 antigenic compoenents in hydatidosis patients sera. The crude antigenic compnenets with 290 Kd, 200 Kd, 125 Kd and 28 Kd molecular weight was only recognized in sparganosis patients sera, but 64 Kd antigenic component was nonspecific antigenic components which were also cross-reacted with sparganosis, hydatidosis, cysticercosis patients sera and normal human sera.

  • The life-span of the sparganum in humans is not exactly known, but it may survive longer than 5 years in some patients. We experienced a case infected with a sparganum that is presumed to have lived for 20 years in a patient's leg. The patient was a 60-year-old woman, and she was admitted to a hospital due to ankle pain that was aggravated on dorsiflexion. She had noticed a mass on her knee some 20 years ago, but she received no medical management for it. The mass moved into the ankle joint 3 months before the current admission, and then the aforementioned symptoms appeared. A living sparganum was recovered by surgery, and the calcified tract near the knee was proved to be the pathway along which the larva had passed.

  • Sparganosis, an infection due to the plerocercoid of Spirometra erinacei, are found worldwide but the majority of cases occur in East Asia including Korea. This report is on a recurred case of sparganosis in the subcutaneous tissue of the right lower leg 1 year after a surgical removal of a worm from a similar region. At admission, ultrasonography (USG) of the lesion strongly suggested sparganosis, and a worm was successfully removed which turned out to be a sparganum with scolex. Since sparganum has a variable life span, and may develop into a life-threatening severe case, a patient once diagnosed as sparganosis should be properly followed-up for a certain period of time. Although imaging modalities were useful for the diagnosis of sparganosis as seen in this case, serological test such as ELISA should also be accompanied so as to support the preoperative diagnosis.

  • Antigenic components reacting with IgE and IgG antibodies were localized in muscular layer of adult and of larva, sparganum. But the antigenic components inducing IgG were localized at tegument and parenchyma in addition to muscular layer in adult and sparganum. Also in sparganum, the surface of calcareous corpuscles of parenchyma showed immunoreactivity to IgG antibody. However antigenic components inducing IgE antibody were not localized in tegument and parenchyma, but in adult worm, we observed the immunopositive reaction at the lining of vitelline follicles in mature proglottis and on surface of egg shell within uterus of graved proglottis. By the method of immunogold-labelling, we observed the location of antigenic particles in tegument of sparganum. The density of antigenic particles inducing IgG was higher than that of antigen particles inducing IgE in syncytial tegument, tegument cells. A total of 43 and 36 protein bands were resolved from crude extracts of adult and sparganum, respectively, by SDS-PAGE. 34 bands from crude extracts of adult and larva were migrated to same positions. By EITB, 21 bands of 44 bands in adult were recognized with IgG antibody, and also 21 bands of 36 bands in sparganum. 13 bands of them were common antigenic components both in the adult worm and sparganum. Because 19 bands of 44 bands in adult worm were reacted with IgE antibody, they were IgE antigenic component. In sparganum, 13 bands were IgE antigenic components. 9 bands of them were common antigenic component inducing IgE antibody in both a-dult and sparganum. 3 bands of antigenic component recognized by IgE and IgG antibody were nonspecific antigen in both adult and sparganum of Spirometra erinacei.

  • A highly specific antigenic protein of 31 kDa from plerocercoid of Spirometra mansoni (sparganum) was obtained by gelatin affinity and Mono Q anion-exchange column chromatography. The purified 31 kDa protein was subjected to N-glycan enzymatic digestion for structural analysis. The relative electrophoretic mobility was analyzed by SDS-PAGE, before and after digestion. On SDS-PAGE after enzymatic digestion, the 31 kDa protein showed a molecular shift of approximately 2 kDa, which indicated the possession of complex N-linked oligosaccharides (N-glycosidase F sensitive) but not of high-mannose oligosaccharides (endo-beta-N-acetylglucosaminidase H, non-sensitive). Chemically periodated 31 kDa protein showed statistically non-significant changes with human sparganosis sera by enzyme linked immunosorbent assay (ELISA). Therefore, the dominant epitopes of the 31 kDa molecule in human sparganosis were found to be mainly polypeptide, while N-glycans of the antigenic molecule in sparganum was minimal in anti-carbohydrate antibody production.
