Hepatocellular carcinoma (HCC), the sixth most prevalent cancer worldwide, continues to have high prevalence in many countries of Asia. The main challenge is the high prevalence of chronic hepatitis and aflatoxin, for example in China. HBV vaccination should be the major preventive tactic in Asian countries. The burden of HCC is low in Iran because most cases are due to HBV and this infection was less common. Although in Iran, a mass vaccination program started in 1993, its impact on decreasing the burden of HCC due to HBV can only be expected in future decades.

Although tuberculosis is highly prevalent worldwide, congenital tuberculosis is one of the least common manifestations of the disease. The diagnosis is usually difficult because of the non-specific clinical presentation and the lack of awareness of maternal disease prior to pregnancy and delivery. We present the case of a preterm neonate with congenital tuberculosis, born to a previously healthy mother who had developed severe disseminated tuberculosis during her pregnancy. Once the diagnosis was confirmed in the mother, the congenital infection was confirmed by isolation of Mycobacterium tuberculosis in gastric aspirates, and positive polymerase chain reaction in a cerebrospinal fluid examination. Treatment for tuberculosis with a four-drug regimen resulted in an adequate clinical response in both the mother and infant.

Deserts around the world mostly do not have plants and are ever- expanding their area each year. There is shortage of food and prevalent hunger around the world mostly in the African countries that have desert. The waste water is not properly managed in those places and it causes disease outbreaks. So, the problems of desertification, waste water management and hunger have to be addressed by the world community. This thesis work tries to explore a possibility of reclamation of deserts with regular application of waste water. The results obtained from a four months long test are very encouraging and it can be easily concluded that the deserts can be reclaimed by application of waste water and it will relieve the desert community from the burden of costly treatment of waste water as well. In turn, they will, to some extent, get rid of water borne diseases and the reclaimed land could be used in future to produce more food to feed the hungry community- positively impacting directly to food security of the focused community.

Human papillomavirus (HPV) type 52 is a high-risk HPV responsible for cervical cancer. HPV type 52 is common around the world and is the most common in some Asian regions. The available prophylactic HPV vaccines protect only from HPV types 16 and 18. Supplementing economical vaccines that target HPV type 52 may satisfactorily complement available prophylactic vaccines. A codon-adapted HPV 52 L1 gene was expressed in the methylotrophic yeast Hansenula polymorpha, which is used as an industrial platform for economical hepatitis B surface antigen particle production in China. We found that the recombinant proteins produced in this expression system could form virus-like particles (VLPs) with diameters of approximately 50 nm. This study suggests that the HPV 52 VLPs produced in this platform may satisfactorily complement available prophylactic vaccines in fighting against HPVs prevalent in Asia.

This study was performed to investigate prevalence of clonorchiasis among the inhabitants living in villages along the 4 major rivers, Nakdong-gang (= river), Seomjin-gang, Youngsan-gang, and Guem-gang in southern Korea. From January to December 2006, a total of 24,075 stool samples (1 sample per an inhabitant) were collected in 23 localities and examined by the formalin-ether sedimentation technique. Of the inhabitants examined, 3,441 (14.3%) were found to harbor various types of intestinal parasite eggs, cysts or larvae. Numbers of infected people were 2,661 (11.1%) for Clonorchis sinensis, 431 (1.8%) for heterophyids, 226 (0.9%) for Entamoeba spp., 57 (0.2%) for Giardia lamblia, 30 (0.1%) for Trichuris trichiura, and 18 (0.07%) for echinostomes. Prevalence rates of clonorchiasis according to the river basin were 17.1% in Nakdong-gang, 11.2% in Seomjin-gang, 5.5% in Youngsan-gang and 4.6% in Guem-gang. Of the 2,661 C. sinensis egg-positive cases, 57.7% was male. The present findings suggest that clonorchiasis is still highly prevalent among inhabitants in the riverside areas of southern Korea, and it is necessary to implement a systematic control program in the endemic areas.

Background: It is axiomatic that average life span is prolonged in proportion to the advance of socio-economic improvements and medical science. Consequently, the number of elderly patients with skin diseases is increasing. Objective: This study was performed to examine the patterns of skin diseases in elderly patients that had visited Dongguk Oriental Medical hospital, Dept. of Dermatology. We also compared these patients to the young generational groups. Methods: We studied 67 elderly patients with complaints of skin diseases who had visited our hospital from March 2000 to February 2002. We analysed their skin diseases and compared them with the younger group's. Results: The results were as follows; 1. The common disease groups were eczema(32.8$\%$); pruritus(23.9$\%$); viral infections (13.4$\%$); psoriasis(9.0$\%$); fungal infections and urticaria(6.0$\%$). 2. The disorders prevalent in men were eczema(30.0$\%$); herpes zoster & pruritus(23.3$\%$); fungal infection(13.3$\%$); psoriasis (3.3$\%$); melasma(6.7$\%$). 3. The common diseases of women's group were observed in the following order; eczema(35.l$\%$); pruritus(24.3$\%$); psoriasis(13.5$\%$); urticaria(10.8$\%$); other dermatoses(8.1$\%$); herpes zoster(5.4$\%$). 4. The most frequent skin disease for those in their 50's was eczema(32.3$\%$); 60's, pruritus(36.8$\%$); 70's, eczema(50.0); and over eighties., eczema and pruritus(40.0$\%$). Conclusion: This study suggests that dermatologic problems in the elderly are very common, especially eczema, pruritus. It is a very different pattern from the younger group's. And we have to better consider more effective management and treatment for them; especially further dermatologic studies including substantial medical care. Usually Oriental medicine is good at treating chronic diseases and less harmful. So we expect it to be generally better for elderly patients than western medicine.

A survey was performed to know the recent infection status of digenetic trematode metacercariae in clams and oysters from 4 sites in western coastal regions of the Republic of Korea (=Korea). Four species of clams (Mactra veneriformis, Ruditapes philippinarum, Cyclina sinensis, and Saxidomus purpuratus) were collected from Taean-gun, Chungcheongnam-do (Province), Buan-gun (County) and Gochang-gun, Jeollabuk-do, and oysters, Crassostrea gigas, from Shinan-gun, Jeollanam-do were transferred to our laboratory on ice and examined by the artificial digestion method. The metacercariae of Himasthla alincia were detected in 3 species of clams, M. veneriformis, R. philippinarum, and C. sinensis from the 3 surveyed areas. The positive rate and the mean density per clam infected were 98.9% (30.8 metacercariae) in M. veneriformis, 60.0% (5.0) in R. philippinarum, and 96.0% (28.4) in C. sinensis. The positive rate (mean density) of Acanthoparyphium tyosenense metacercariae in M. veneriformis was 50.0% (2.1) from Taean-gun and 70.0% (2.8) from Gochang-gun. The metacercariae of Parvatrema spp. were detected in M. veneriformis and R. philippinarum from Taean-gun and Gochang-gun; the positive rate (mean density) was 63.3% (4,123) and 50.0% (19) in M. veneriformis, and 6.7% (126) and 100% (238) in R. philippinarum from the 2 regions, respectively. The metacercariae of Gymnophalloides seoi were detected in all 30 oysters from Shinan-gun, and their average density per oyster was 646. From the above results, it has been confirmed that more than 3 species of metacercariae are prevalent in clams from the western coastal regions, and G. seoi metacercariae are still prevalent in oysters from Shinan-gun, Jeollanam-do, Korea.

The infection status of Clonorchis sinensis metacercariae (CsMc) was examined in freshwater fish from a highly prevalent site, Wicheon (a branch of Nakdong-gang), which is located in Gunwi-gun, Gyeongsangbuk-do, the Republic of Korea. Total 1,162 fish in 32 species were examined by the artificial digestion method through 6 years. CsMc were detected in 720 (67.5%) out of 1,067 fish (26 spp.) and their density was 610 per fish infected. In the susceptible gobioninid fish group, i.e., Pungtungia herzi, Squalidus gracilis majimae, Squalidus japonicus coreanus, Sarcocheilichthys variegatus wakiyae and Pseudorasbora parva, all of 323 fish were infected with an average of 1,310 CsMc. Total 23 (95.8%) gobioninid fish, i.e., Pseudogobio esocinus, Abbottina springeri, Hemibarbus longirostris, Microphysogobio koreensis, and Microphysogobio jeoni, were infected with 127 CsMc in average. In the acheilognathinid fish (bitterlings) group, the prevalence was 77.0%, and the density was 50 CsMc per fish infected. In the rasborinid fish (chubs) group, i.e., Zacco platypus, Zacco temminckii, Zacco koreanus, and Opsariichthys uncirostris amurensis, 147 (36.5%) out of 403 fish examined were infected with 15 CsMc in average. The susceptibility indices of CsMc were 412 in the overall positive fish group, 1,310 in the gobioninid group-1, 122 in the gobioninid group-2, 38.5 in the acheilognathinid group, and 5.5 in the rasborinid fish group. Conclusively, it was confirmed that CsMc are highly prevalent in fish from Wicheon, and their infection tendency varied according to the subfamily groups in Cyprinidae fish hosts.
