A parasitic survey on vegetables collected from markets and vegetable gardens in Taegu area was conducted for the discovery of human parasitic eggs and larvae. Three species of vegetable, lettuce (Lactuca sativa), young radish(Raphanus sapivus) and Chinese cabbage (Brassica pekinensis) were selected. All vegetable leaves were washed with a hard brush, and then species of parasites and the approximate mean number of parasitic eggs per 200 grams of vegetable leaves were investigated. When vegetables collected from markets were examined, 5 species of parasite eggs (ascarid, trichurid, Trichostrongylus, Clonorchis and hookworms) and 2 larvae (filariform and rhabditoid ) were found. Furthermore, a number of eggs and larvae of undetermined species were also observed. Of the parasites studied, ascarid egg was found to be highest (49.0%), followed Trichostrongylus egg(18.0%) as well as filariform larva of hookworms (19.7%), and the least often observed was rhabditoid larva of hookworms(0.7%). The recovery rate of parasites among lettuce, young radish and Chinese cabbage collected from markets ranged from 23.2 to 91.9 percent and was similar to that from vegetable gardens, where Chinese cabbage showed the highest (91.1%) and lettuce being next(49.0%) in positivity of ascarid eggs. In the case of filariform larva, the rate of Chinese cabbage was twice as high as that of lettuce and young radish. There was a significant reduction in the rate of filariform larva, suggesting that a single washing of vegetables at the vegetable washing stand would reduce the number of parasites attached to vegetable leaves, when young radish washed at the stand was compared with that unwashed. In the monthly rate of parasites recovered from young radish, there was significant fluctuations between the eggs and filariform larva of hookworms. The mean number of ascarid egg per 200 grams of vegetable was 7.5 in young radishes, 3.1 in lettuces, and 0.5 in Chinese cabbages, in decreasing order. It is noteworthy that young radish contained more than 10 times more than Chinese cabbage. These results would seem to indicate that one of the important routes of infection is due to consumption of pickled young radishes in summer than pickled Chinese cabbages in winter.

Disseminated superficial actinic porokeratosis (DSAP) is one of the recently found skin disorderes, which was differentiated from classicaI porokeratosis (Mibelli) and senile keratosis etc. in view of clinical features and hietogenesis by Marvin E. Chernosky on 1967. The one was 60 years old female patient, who had been suffered from multiple dark-brownish keratotic uniform minute papules on dorsa of the hands, forearms and neck with accompanying itching sensation since about 20 year's old of her age. The another one was 38years old housewffe, wha had been suffered from same lesions of the former on the face, neck, extremities especially sun-light exposed area. In both cases, skin lesions were exacerbated during each summer season and increase in numbers of the skin lesions with more severe itching sensation. Chernosky postulated none of a dark-sklnned race affording natural protection against sun-light had skin lesion of D S A P, we were abIe to find out two cases of typical D S A P ih the Korea.

Sixty four leprous claw hands had been operated on for intrinsic replacement extensor-extensor many tailed at the Department of Orthopedic Surgery, Kyungpook National University Hospital during the period from 1966 to 1970. The follow up study was carried out for fourty-one hands from one year to four years and nine months after operation, and evaluated by the following assessments. 1. Fully open hand assessment 2. Lumbrical position assessment 3. Hook position assessment 4. Closed fist assessment 5. Mechanics of closing 6. Separate finger movement in lumbrical position The results obtained were as follows: 1. The most of the cases were median-ulnar palsy. 2. The majority of them were in third decade young men. 3. Satisfactory result was 63.5% in appearance, 70.8% in function, 62.8% according to the patients statement, and 61.1% in overall total assessment. 4. As complication two cases of severe adhesion of the grafted tendons and significant lateral deviation on nine fingers were noted. 5. Preoperative and postoperative physiotherapy contributed a important roll in the end results.

PURPOSE: Although influenza is regarded as one of the major causes of morbidity and mortality in children with cancer, the actual vaccine coverage remains poor. We conducted evaluation of immunogenicity and safety of influenza vaccine in children with cancer. METHODS: In this study, 25 children with cancer who received influenza vaccine (SK influenza IX vaccine(R)) at the Korea Cancer Center Hospital between October and December 2009 were analyzed. Blood samples of patients were collected twice (at the beginning of this study and at 30th day after vaccination) and their antibody titers were measured using the hemagglutination-inhibition (HI) assay. Immunogenicity of the influenza vaccine was assessed by seroprotection rate on days 0 and 30, seroconversion rate on day 30, and mean fold increase (MFI) of geometric mean titer (GMT) of HI between days 0 and 30. RESULTS: Any of the subjects in our study did not experienced serious adverse events after influenza vaccination. Seroprotection rates were 68% for H1N1, 40% for H3N2, and 36% for B. Seroconversion rates were 12% for H1N1, 16% for H3N2, and 20% for B. MFIs were 0.9 for H1N1, 1.2 for H3N2, and 1.8 for B. CONCLUSION: In the study, we found a limited protective immune response to influenza vaccine, among subjects with cancer. However, some subjects showed seroconversion, and there were no severe adverse events among all subjects, supporting the recommendation of annual influenza vaccination in children with cancer.

OBJECTIVE: To elucidate the correlation of nitric oxide (NO) concentrations in follicular fluid (FF) with the ovarian response as well as the age in women undergoing controlled ovarian hyperstimulation (COH). METHODS: This study was performed in 72 cycles of whom underwent COH for in vitro fertilization at infertility clinic of Changwon Hanmaeum Hospital and Pusan National University Hospital from Aug., 2003 to Dec., 2003. Each FF was collected at the oocyte retrieval and NO concentrations in FF were assessed. We analyzed the correlation of NO concentrations in FF with the ovarian response as well as the age in women undergoing COH. RESULTS: Among 72 cycles, the clinical pregnancy rate was 37.5% (27cycles). There were no significant differences in patient's age, ampules of gonadotropins used, estradiol level on the day of hCG administration, the number of oocytes retrieved, and fertilization rate between pregnant and nonpregnant groups. However, negative correlation was found between the follicular size and NO concentrations in FF. No significant correlation was found between age and NO concentrations in FF. Comparing NO concentrations in FF between pregnant and nonpregnant women by age, NO concentrations in FF were higher at nonpregnant women, significantly those of them more than 40 years old. CONCLUSION: These results suggest that NO concentrations in FF cannot be a marker for the ovarian response, and have no correlation with all parameters of COH including patients' age with exception for the follicular size.

In order to investigate the role of H2-M molecule on class II molecule other than H2-Ab we made H2-M deficient H2-E transgenic mice and to see the peptide diversity on H2-E molecule in these mice, we contructed AND --> H2-M deficient H2-E transgenic bone marrow chimeras. The results were as followings. 1. The phenotype of thymus of H2-M deficient H2-E transgenic mice showed similar CD4 and CD8 single positive thymocyte amount as normal wild type B6 mice with CD4/CD8 ratio around 2. The percentage of double positive cells were about 85%. 2. In the periphery, H2-M deficient H2-E transgenic mice also showed similar amount of CD4 and CD8 cells as normal wild type B6 mice. The CD4/CD8 ratio was 1.5~2. 3. The development of transgenic CD4 cells from AND --> H2-M+/- H2-E transgenic bone marrow chimera was similar to wild type AND transgenic mice. 4. The development of transgenic CD4 cells from AND --> H2-M deficient H2-E transgenic bone marrow chimera was reduced compared to wild type AND transgenic mice or AND --> H2-M+/- H2-E transgenic bone marrow chimeras. But the amount of CD4 cells developed in these chimeras were significant and H2-E molecule could bind some self peptides in the absence of H2-M molecules and support the CD4 cell development in these chimeras.

In order to find out the proliferative ability and functional capacity of peripherally expanded mature T cells, syngeneic lymph node cells were injected into thymectomized and irradiated adult mice. Donor and host T cells were evaluated in specific time points. The results were as followings. 1. As compared to the engrafted lymphocytes after transfer, we observed 54~60 fold increase in CD4 T cells and 113~130 fold increase in CD8 cells, that is, CD8 cells proliferated more than CD4 cells in the periphery. 2. Mature T cells proliferated in the periphery got activated/memory phenotype in the early period of expansion but they upregulated CD45RB and CD62L in the later period. CD44 level remained high. 3. T cells maintained their response against soluble antigen, KLH but the reactivity against some polyclonal T cell activators, such as anti-CD3 antibody and concanavalin A were reduced severely in the 6 month expanded group. 4. The leftover host T cells also proliferated in the space and they behave similar to donor T cells in proliferation and change of activation/memory markers.

The purpose of this study was to investigate the effect that three resin indexing materials had on the distortion of split cast in the procedures of solder indexing and block fabrication. The specimen had two cylinders and connecting bar. Two cylinders were a reference cylinder and a test cylinder that were machined precisely and placed on metal base. The total of specimens wee 30 and they were divided into 3 groups according to the resin indexing materials : Acrylic solder , G-C Pattern resin , Z-100 . The relative coordinates (X, Y, Z) of centroids of both cylinders were measured by using 3-D coor dinates measuring machine. The value of indexing distortion was obtained after application of indexing material, and the value of the block distortion was obtained after fabrication of soldering block, and the value of total distortion was a value sum of indexing distortion and block distortion. Intercentroidal linear distortion({{{{ SQRT {X'^2 + Y'^2 +Z'^2 }- SQRT {X^2 + Y^2 +Z^2} }} }}) and global distortion {{{{rm SQRT {(X'-X)^2 +(Y'-Y^)2 +(Z'-Z^)2} }} }} were calculated from data of coordinates of centroids at each mea s u r ing stages. The results of this study were as belows ; 1. The intercentroidal distance between the split casts was reduced by indexing distortion and increased by block distortion. 2. The indexing global distortion between the split casts was smaller than block global distortion. 3. The intercentoidal linear distortion and the global distortion were no significant difference between indexing materials.
