Although Echinostoma hortense is one of the intestinal trematodes with a high infection rate in South Korea, the exact immune response against E. hortense infection has yet to be fully investigated. In the present study, we investigated differential susceptibilities in two different strains of micenamely, BALB/c (H-2d) and C3H/HeN (H-2k) mice. Likewise, we(More)
Two rare cases of human infection with parvum (dwarf) type of Diphyllobothrium latum [syn. D. parvum (Stephens, 1908)], were discovered in Korea. The first case was a 46-year old housewife, from whom a kind of pseudophyllidean tapeworm eggs was detected in the feces. She was treated with praziquantel and purged, and a complete strobila with scolex, 120 cm(More)
An epidemiological survey was performed to know the infection status of oysters with Gymnophalloides seoi metacercariae in 7 islands of the West Sea known as the habitat of paleartic oystercatchers, Haematopus ostralegus osculans, in Korea. The surveyed areas were Aphaedo (Shinan-gun, Chollanam-do), Jangjado, Sonyudo and Munyodo (Okdo-myon, Kunsan-shi,(More)
Despite the increasing incidence in food-borne Echinostoma hortense infection, the underlying immune mechanism along with the clinical manifestations and the expulsion of the worms from the mucosal surfaces are not well understood. To clarify the differences in the immune mechanisms induced by E. hortense in the host, we examined the interleukin (IL)-4,(More)
Mucosal mast cell (MMC) responses and worm recovery rates in rats infected with Echinostoma hortense were investigated from day 3 to day 56 post-infection (p.i.). Experimental infected group showed apparently higher number of MMC in each part of the small intestine than that of the control group. The number of MMC in the duodenum increased gradually after(More)
Asthma is an inflammatory airway disease. The pathogenic mechanisms of asthma include the infiltration of leukocytes and release of cytokines. Mimosa pudica (Mp) has been used traditionally for the treatment of insomnia, diarrhea and inflammatory diseases. Although Mp extract has various therapeutic properties, the effect of this extract on asthma has not(More)
Although recent studies have shown that several pro-inflammatory proteins can be used as biomarkers for atherosclerosis, the mechanism of atherogenesis is unclear and little information is available regarding proteins involved in development of the disease. Atherosclerotic tissue samples were collected from patients in order to identify the proteins(More)
In order to verify the role of migrating birds as natural definitive hosts for Gymnophalloides seoi (Gymnophallidae), Palearctic oystercatchers, Haematopus ostralegus, were caught from several western coastal areas in the Republic of Korea and examined for intestinal flukes. Five (71.4%) of 7 oystercatchers were infected with 302-1,660 (mean 892) adult G.(More)

The present study was performed to know the epidemiological status of echinostomiasis in the Chungju Reservoir and upper streams of Namhan River, together with an experimental study on the life history of Echinostoma hortense. The stool specimens of 169 inhabitants and 473 junior high school students from 5 different villages revealed 3 (0.5%)(More)
The DNA-interactive drug, echinomycin, is a potent antitumor agent, which is able to induce apoptosis in a multitude of cancer cell lines. Previously, we showed that echinomycin strongly inhibited the growth of a variety of cancer cell lines, and the activation of mitogen-activated protein kinases (MAPK) in human colon cancer cells (HT-29). However, little(More)
