Lots of cases relating Helicobacter pylori infection to iron-deficiency anemia have been described in the literature and H. pylori infection has emerged as a cause of refractory iron-deficiency anemia which is unresponsive to oral iron therapy. H. pylori-associated iron-deficiency anemia can be treated by H. pylori eradication. It is not thought to be attributable to gastrointestinal blood loss, such as duodenal ulcer. The mechanism by which H. pylori infection contributes to iron-deficiency anemia remains unclear. However, four possible explanations can be posited for this relationship; occult blood loss secondary to chronic gastritis, reduced iron absorption due to hypo- or achlorhydria, increased iron consumption by H. pylori, and iron sequestration in gastric mucosa. H. pylori-associated iron-deficiency anemia seems to develop in populations at increased risk for iron depletion. When pubescent girls, including athletes, are found to have iron-deficiency anemia refractory to iron administration, they should be evaluated for H. pylori infection.

Outbreaks of foulbrood in honey bees rearing on Cheju Island(an apiary with 172 colonies) and in Pusan City(an apiary with 100 colonies) were reported in April, 1987. The disease striked on Cheju Island was identified as American foulbrood caused by Bacil

Objectives : The prevalence of peptic ulcer disease is estimated about 10% in Korea, and has declined due to Helicobacter pylori eradication therapy. Symptoms of peptic ulcer are postprandial epigastric pain, hunger pain, anorexia, nauea, vomiting, soreness, postprandial fullness, postparandial discomfort. The purpose of the study was to evaluate the effectiveness of the Anjungsan in the improvement of the symptoms in patients with peptic ulcer. Methods : After taking Anjungsan to patient with peptic ulcer, Examined to assess the improvemnet by Ordinal Scale VI grade and VAS. Results : Patients with symptoms of the appeal was taking Anjungsan gets better after 3 dyas appeared to be more than half. And 11 days after treatment all symptoms were improved under the VAS 1-2 except for epigastric lump sensation. Conclusions : After treatment with Anjungsan, patient showed improvement in all symptoms associated with peptic ulcer.

The use of Japanese stylish terms in the Korean fishing vessels has been overdoing. It becomes a reason of preventing the communications between crews who have been working for many years and the beginners who newly work for the ships. Also the experienced crews cannot easily understand the contents of the texts and manuals for marine ship's machinery because the terms explained in the books are very different from those they always speak in the ships. It is reasonable to expel Japanese stylish terms from the vessel if possible to enable free communications to each other. I inspected and examined about 122 Japanese stylish terms that is spoken in the engineering part of the fishing vessels. So, I expect this paper is a basic research for the eradication of the Japanese stylish terms in the Korean fishing vessels.

Congratulations on the 40th Anniversary of KAHP, which has made great contributions to the control of parasitic diseases in Korea, and to the development of collaboration with China and other Asia countries aiming at the common interest. The 40 years of KAN/KAHP and its predecessor, Korea Association of Parasite Eradication has composed a brilliant road map to bring the prevalence of intestinal parasite infection from 84.3% in 1971 to the current prevalence of 2.4%, and to endeavor in the promotion of the health of children, man and woman, and low income families in Korea, as well as to generously share the successful experience in parasite control with China during the last half century. Indeed, the 40th birth day of KAHP is marked with great achievements and bright future.

Estimated number of adults and children newly infected with HIV-1 during 2001 alone is 5 million in total. An effective vaccine, in addition to education & public health approaches, has been believed to be the best option to stop the HIV-1 transmission, especially for developing countries. Among AIDS vaccine candidates, DNA vaccine is relatively safe and, in a certain extent, mimics some attributes of live attenuated vaccine, with regard to in vivo gene expression & the type of immunity induced. We recently demonstrated that DNA vaccines expressing SIVmac239 structural and regulatory genes, augmented with coadministration of IL-12 mutant induced the strongest T cell responses, resulting in low to undetectable setpoint viral loads, stable $CD4^+$ T cell counts, and no evidence of clinical diseases or mortality by day 420 after challenge. This finding is the second demonstration, following the protective result of live attenuated SIV vaccine in SIVmac-rhesus monkey model, which was known to have safety problem. So, our DNA vaccines could give a significant impact on HIV-1 epidemic by slowing or stopping the spread of HIV-1, leading to eventual eradication of HIV-1 and AIDS in the population.

Korea Parasite Eradication Association alleged in its seasonal report spring/1975 that 36.8 percent of primary, middle and high school students in Seoul area are infected with parasites. For the purpose of a comparative study between the high rate of parasite infection among Korean students and that of parasite eggs attached to vegetables which perform intermediary role in carrying the eggs to human body, such vegetables as lettuce, Korean cabbage, young radish, green onion, cabbage which are on sale at several markets in Seoul city are sampled at random for study. The infection rate of parasitic eggs and larvae on vegetables is studied twice while the detaching mean while removing rate of eggs and larvae in proportion to the number of washing them is studied three times. Every 300 grams of vegetables is taken at random for examination and every one of them is washed with a hard brush and then the kinds of parasite eggs and the ratio of eggs attached to them are studied.

One single lactic acid producing bacterium, isolated from kimchi, inhibited the growth and adherence of Helicobacter pylori to the human gastric epithelial cell line MKN-45. This isolate was identified as Lactobacillus plantarum and termed L. plantarum strain PL9011. The adherence of H pylori, in the presence of live or nonviable L. plantarum strain PL9011 (10-fold CFU), decreased to 14-20%. The spent culture supernatant of L. plantarum strain PL9011 resulted in the eradication of H pylori. This activity remained stable following neutralization and heat treatment, but not following pepsin treatment, thereby suggesting small peptides as the inhibitory factor. L. plantarum strain PL9011 did not produce any harmful metabolites or enzymes. The results obtained in this study suggest that the L. plantarum strain PL9011 may be a potential novel probiotic for the stomach.

Accesses to lands, houses, the Internet and other utilities are regarded as basic human needs to escape poverty and are required to recognize the relationships between the digital divide and socio-economical inequality. The digital divide might not be a single technical disparity, but stems from a complicated mixture of economic and socio-technical symptoms of inequality. There is growing awareness of scrutinizing causal mechanisms between the digital divide and poverty since combating poverty could be a primary step to mitigate the digital divide. In this paper, the Hexad model is proposed to explicate poverty interpretation by using 6 parameters as a major tool for partly assisting in poverty monitoring system in connection with land information. A solution model of the Internet is suggested to break the digital divide. It expounds a conceptual framework and new idea for poverty management to notify spatio-temporal locations of poor actors and geography of the digital divide when efforts of poverty eradication hinge on understandings of geographic location of digital disadvantaged groups through parcel-based land information.

In this paper, a kind of pest-predator model with impulsive effect and infinite delay is considered by the method of chain transform. By using Floquet's theorem, it is shown that there exists a globally asymptotically stable periodic pest eradication solution when the impulsive period is less than or equal to some critical value which is a directly proportional function with respect to the population of release. Furthermore, it is proved that the system is permanent if the impulsive period is larger than some critical value. Finally, the results of the corresponding systems are compared, those results obtained in this paper are confirmed by numerical simulation.
