The distribution of glycogen, polysaccharide, mucopolysaccharide, lipid and nucleic acid has been studied in Echinorhynchus gadi(Acanthocephala). The results were summarized as follows: Glycogen and polysaccharide was demonstrated by Bauer PAS reaction technique and was found in fertilization membrane in ovum, central nuclear mass in acanthor and lemnisci, hypodermis in cystacanth. Mucopolysaccharide was demonstrated by Mowry alcian blue staining technique and was found in outer membrane, fibrillar coat, fertilization membrane and inner membrane in acanthocephalan ova. Lipid was demonstrated by Smith Nile blue stain and Lison Sudan black B staining technique and was found roughly parallel to that of polysaccharide. Nucleic acid was demonstrated by Rosenbeck Feulgen reaction, Taft methylgreen-pyronin stain and Diengdoh acridine orange staining technique and found in central nuclear mass in acanthor, also, was found in lemnisci, proboscis and hypodermis in cystacanth.

OBJECTIVE: Although the use of cytology in screening has reduced morbidity and mortality from invasive cervical cancer, there has been limitation because of the low sensitivity and high false negative rate in the detection of preclinical or clinical disease of the cervix. This study was performed to explore the usefulness of Hybrid Capture System HPV DNA test as a diagnostic method of the cervical cancer. METHODS: Cervical cytology and Hybrid Capture System 1 (HCS1) HPV DNA test were performed in 1,023 women who visited Gynecologic Oncology Clinic in Guro Hospital, Korea University Medical Center. HPV DNA were retested by HCS1, HCS2 and Polymerase Chain Reaction(PCR), in randomly selected 200 women to compare these DNA tests. RESULTS: While the sensitivity and specificity of cervical cytology in detection of cervical lesion were 71.2% and 89.5%, those of HCS1 HPV DNA test were 63.0% and 86.9% respectively. There was significant difference in detection of cervical precancerous lesions between HCS1 and HCS2 (P<0.05), but not between HCS2 and PCR (P=0.14). And the sensitivity and specificity were improved with combining cytology and HCS1 HPV DNA test(82.2%, 86.9%~). CONCLUSION: HCS HPV DNA test may be considered as a useful adjunctive test with cervical cytology in cervical cancer screening.

OBJECTIVE: To evaluate the effect of computer-assisted cognitive training program (RehaCom®) on cognitive function of the patients with stroke. METHOD: Fifty seven subjects with stroke (34 males, 23 females) were enrolled and classified into two groups, experimental and control group. There was no significant difference between two groups in age, sex and lesion type distribution. Control group received conventional rehabilitation therapy including physical and occupational therapy. Experimental group received additional computer-assisted cognitive training using RehaCom software (Germany, 1996), 5 times per a week, 30 minutes per session, for 4 weeks. The RehaCom software consisted of reaction behavior, memory of words, topological memory programs. All patients were assessed their cognitive function using Computerized Neuropsychological Test (CNT), Lowenstein Occupational Therapy Cognitive Assessment (LOTCA) and Korean Version of Mini-Mental Status Examination (MMSE-K) before and after treatment. Functional independence measurement (FIM) was also applied for evaluation of functional status. RESULTS: There was no difference between two groups in the LOTCA, CNT and FIM scores at baseline. Four weeks later, scores of the MMSE and FIM were significantly improved in the experimental group compared to the control group (p<0.05). Especially, the improvement was significant in moderate cognitive impairment group (MMSE = 11~21) (p<0.05). In learned patients of experimental group, the score of the MMSE and LOTCA were significantly more improved than control group (p<0.05). CONCLUSION: Computer-assisted cognitive training would be useful as a additional tool of cognitive rehabilitation in patients with stroke. Especially, the effect of computer-assisted cognitive training program was far better in patients with moderate cognitive impairment and in patients who show learning in cognitive training program.

The bone marrow biopsy is an integral part of the staging process in patients with malignant lymphomas. Bone marrow(BM) involvement indicates stage IV disease, but there are always a lot of cases in which clear separation is not possible when based on morphology alone. Additional difficulties are caused by morphologic discordance between the BM and the primary lymphoma. Immunohistochemical stain, mRNA in situ hybridization (ISH) for light chain restriction and polymerase chain reaction (PCR) for IgH CDR3 and TCRgamma were performed to find a minimal lesion and the clonality in formalin fixed paraffin embedded tissues of 39 primary lymphomas and corresponding BM biopsy specimens. As a result, nine morphologically negative bone marrows of 18 lymphomas were positive by PCR (Group I). Among the 6 lymphoma cases with morphologically suspicious BM involvement (Group II), one was confirmed to be positive for marrow involvement by both mRNA ISH and PCR and the other four by PCR alone. The positive bone marrows of Group I and II revealed gene rearrangement at the same site as the primary lesion, suggesting the same clonality. Thirteen of 15 lymphomas with morphologically positive BM (Group III) had the same clonality in the primary lymphomas and the BM lesion. Three cases among the Group III with morphologic discordance also revealed the same clonality by PCR. This study shows that a combination of mRNA ISH and PCR in addition to an immunohistochemical stain improves the diagnostic sensitivity in the detection of BM involvement and identification of clonality. Among the three different methods used, PCR is the most sensitive in detecting a minimal lesion.

PURPOSE: The purpose of this study is to compare the present nutritional status with that of previous surveys done in Korea and other advance countries. METHODS: We measured the arm circumference and triceps skinfold thickness of 1,009 students of Hanyang Elementary School. We analyzed the arm muscle area and arm fat area. We analyzed the lomgitudinal height and weight of 6th grade children. We used an obesity index to estimate the prevalence of obesity. RESULTS: The mean height increased to 4.2-6.6cm in boys, 3.7-6.3cm in girls and the mean weight increased to 3.7-9.7kg in boys, 3.2-8.2kg in girls. The median of arm circumference increased to 7-44mm in boys, 8-36mm in girls. The median of triceps skinfold thickness increased to 1.7-7.8mm in boys, 2.3-6.4mm in girls. The mean of arm muscle area increased to 1.0-7.4cm2 in boys, 0.2-5.4cm2 in girls. The mean of arm fat area increased to 2.4-9.6cm2 in boys, 3.0-8.9cm2 in girls. The prevalence of obesity was 27% in boys and 24% in girls. CONCLUSION: Current data revealed marked increase in arm circumference, triceps skinfold thickness, arm muscle area and arm fat area than those of previous standard data established in Korea, 1984, approaching 1981 U.S standards. The increase in arm fat area and increased prevalence of obesity suggest an increased intake of calorie with relative deficiency in physical activity.

PURPOSE: To report a case of Serratia marcescens endophthalmitis following phacoemulsification and posterior chamber intraocular lens implantation. CASE SUMMARY: A 64-year-old male with a history of diabetes, hypertension, cardiovascular disease was referred with right ocular pain and reduced vision 1 day after cataract surgery. On admission, hypopyon on anterior chamber by slit lamp examination and anterior vitreous was hazy according to ultrasonography. We immediately performed intravitreal antibiotics injection and microbiological analysis of anterior chamber and vitreous samples was performed. On day 3, persistent cornea stormal infiltration and cornea perforation were visible and the organism was identified as S. marcescens. Despite appropriate antibiotic treatment the eye continued to deteriorate. CONCLUSIONS: S. marcescens endophthalmitis was diagnosed and treated immediately, but rapid progression and outcome were unsatisfactory.
