Renal papillary necrosis occurs most commonly in association with urinary tract infection, diabetes mellitus, sickle cell disease, vascular disease, and analgesic nephropathy. Clinical presentation may be related to symptoms of pyelonephritis such as flank pain, renal colic, hematuria, Proteinuria, recurrent fever. The necrotic tissue may be sloughed off, and the diagnosis can sometimes be made by finding piece of renal medullary tissue in the urine. Pyelography may demonstrate cavities and sinuses in the resion of papillae. Anuria & oliguria can lead to the acute renal failure, and especially prognosis and progress may be affect influenced by urinary infection. We report a case of renal papillary necrosis with ingestion of bear gallbladder. On pyelography, Persistent contrast is diagnostic clue of renal papillary necrosis. This case is not be related to urinary tract infection, but occurred acute renal failure. Expectant treatment was gone.

The construction technique of exposed concrete wall without any defect has known one of the difficult task to the engineers who worked in the civil and building construction field. For this reason, the self compacting concrete technique has been widely applied especially for the very thine concrete wall construction. The objective of this study is to provide the reference date on the manufacturing method for self compacting concrete which has self compacting capability without segregation. The mixing proportion tests for flowing concrete which uses superplasticizer are carried out using W/C ratio between 55~44% which represents the normal compressive strength range 210~280kgf/cm². The experiment results show as follows. 1. Within the normal compressive strength range, the suitable W/C ratio was under 45% in the case of only superplasticizer used for the manufacturing self compacting concrete. 2. The suitable slump flow range was 60cm ± 5cm in the case of the W/C ratio 44%. 3. The suitable S/A ratio was 46% in term of flow and compressive strength in the case of the W/C ratio 44%. 4. There is a little difference between vibrating compaction and self compacting method in term of compressive strength.

Acanthamoeba spp. spread in soil, ponds, air and swimming pool, cause a granulomatous amoebic meningitis and amoebic keratitis in human and experimental animals. Their classification had depended upon morphological characteristics and physiological conditions such as thermophilic status and generation times. However, because amoeba species showed the morphological and physiological diversity in isolates, many attempts have been made on identification of Acanthamoeba spp. Restriction fragments length polymorphism (RFLP) analysis of IBS-small subunit ribosomal RNA (srRNA) was an useful tool for classification among morphologically and genetically closely-related species. In this study, 18S-srDNAs of amoebae were amplified by PCR with primer encoding 18S-srRNA gene and digested with restriction endonudeases, and RFLP analysis was applied on classification of Acanthamoeba Korean isolates (YM-4, YM-5 and YM-7), comparing with reference amoebae, A. culbertsoni, A. polyphaga and A. royreba. Trophozoites of six Acanthamoeba spp. had typical acanthopoda, but did not show any morphological differences. Cyst of Acanthamoeba sp. YM-7 was similar to that of A. polyphaga which was designated as group Ⅱ Acanthamoeba. Morphologically other amoebae belonged to group Ⅲ Acanthamoeba. Digestion of 18S-srDNA with six enzymes, Dde Ⅰ, Hae Ⅲ, Hind Ⅲ, EcoR Ⅰ, Rsa Ⅰ and Sph Ⅰ, resulted in various DNA fragments. Using the method of Nei and U (1979) for RFLP analysis, genetic divergence was not observed between A culbertsoni and Acanthamoeba sp. YM-4. Between A. culbertsoni and Acanthamoeba sp. YM-5, genetic distance was 0.070, 0.364 between Acanthamoeba sp. YM-4 and A. polyphaga, and 0.277 between Acanthamoeba sp. YM-7 and A. polyphaga. In comparison with A. culbertsoni and A. polyphaga, Acanthamoeba sp. YM-7 showed genetic distance of 0.330 and 0.154, respectively. Thus, Acanthamoeba sp. YM-7 is a similar species to A. polyphaga. Acanthamoeba sp. YM-5 is a different species from A. polyphaga, but closely-related to A. culbertsoni. Acanthamoeba sp. YM-4 can be classified as a subspecies or a strain of A. culbertsoni.

In Korea, a large number of the mentally ill are still institutionalized in asylums where they can not receive modern psychiatric treatments. This survey was designed to investigate previous treatment methods of these psychiatric patients and to offer basic data in order to develop modern psychiatric delivery system for patients institutionalized in asylums. The 694 subjects who could give cooperative informations wee selrected form 6 asylums which are located in the Kwang-ju and Chonnam area. The data on this survey was collected by investigator's interview from Mar. 30, 1987 to Apr. 10, 1987. The previous treatment methods were divided into 8 groups(modern psychiatric treatment, asylym, Korean shamanic rite, religious healing, herb medicine, drug store, others and no treatment) and multiple responses were allowed. The methods were studied relating to the following psychiatric and sociodemographic factors : psychiatric diagnosis, age at the time of institutionalization, morbid duration before institutionalization, sex, occupation, residence, religion, economic status, marital status, educational level, and guardian. 49% of the patients had no experienced any previous treatment for their mental illness. 35% of the patients had been given modern psychiatric treatment and 23% had been previously institutionalized in asylums. The other treatment methods were reported in less than 10% of the patients. There were significant relationships between the choice of treatment methods and the psychiatric and sociodemographic factors.

The present study investigated not only the feasibility of organotypic spheroid culture system taken from human malignant gliomas but also the similarities and differences between surgical specimens and cultured spheroids using light microscopy electron microscopy, and flow cytometric examination. Surgically resected tumor specimens from eighteen human malignant gliomas were minced and explanted into agarose-coated culture wells. After three to five days these microtumor fragments emerged as spheroids and could be maintained as organotypic spheroids for more than eight weeks. Measurements of the spheroids showed that they decreased during the initial two to three weeks and afterwards remained unaltered over a specific period of time. This growth pattern of the spheroids was consistent with the condition of tumors in vivo suggesting the linkage of cell proliferation and loss. Light microscopic and electron microscopic studies of the spheroids demonstrated that morphological structures were similar to those of the original tumor tissue in vivo and histopathologic characteristics of the original tumor were maintained over a long culture period. The spheroids contained connective tissues, blood vessels, macrophages and neutrophils maintaining a three-dimensional architectural resemblance to the original tumors. Of three pairs of the surgical and spheroid specimen examined by the flow cytometry, one showed a change of ploidy pattern and two contained increased fictions of proliferating cells. It is concluded that this microtumor spheroid system can maintain the characteristics of the original tumors and may serve as an alternative to the in vivo xenograft model for the research of brain tumor biology, invasion and immunology while providing a valuable technique for the evaluation of new therapies such as biological response modifiers.

Mucinous tumor are cystic tumors with loculus lined with mucin-secreting epithelium constitute approximately 8-10% of primary epithelial ovarian tumors. Of all mucinous neoplasms, 75-85% are benign. It is often reach very large size particularly with the benign counterpart being reported on occasion to have exceed 100 lbs. Malignancy develops in 5-10% of benign mucinous cysts. About 15-20% of neoplasms are bilateral. We experienced a huge ovarian mucinous tumor of 155 ㎏. measured 42 × 30 × 28 ㎝ in size, and the volume of cystic contents was about 10 L in a nulligravida 36-year-old woman. Pathologic diagnosis was moderately differentiated mucinous cystadenocarcinoma of right ovary. So, we presented with a brief review of literatures.

Objective : The third molars, expecially mandibular wisdom teeth, are commonly obliquely impacted, and surgical procedure with odontomy and osteotomy is necessary for their extraction. The surgical extracion of impacted wisdom teeth occasionally in duces variable discomfort. Especially, postoperative swelling, pain and limitation of mouth opening determine the degree of discomfort. For the reduction of these complicaions, drug therapy(antihistamine, enzyme, steroid), cole pack and pressure technique have been studied. It is known that the steroids are the most effective. Methods and Meterial : We selected fifty patients in their twenties, who visited Department of Dentistry, Pusan Paik Hospital from March to August in 1998. All of 50 patients has no other medical problems. Total 50 patients were randomly divided to 30 of experimental group and 20 of control group. The experimental group had orally administration of methyprednisolone 5㎎ every 8 hours 2 times preoperatively and 7 times postoperatively. Five points were marked on the patients' face, and the distances between the points were measured just before operation and 48 hours after operation. Results : Methyprednisolone reduces swelling about 50% after surgical extraction of obliquely impacted mandibular third molars with osteotomy and odontomy. The difference in the amount of tissue edema between experimental and control group was significant(p<0.01). However, there was no significant difference according to the operation time. Conclusion : It seems that the use of methylprednisolone is effective to reduce postoperative swelling following surgical extraction of third molars.

In this thesis, We have measured the effect of Al₂O₃ to the magnetic properties of Sr-ferrite. The specimens have been composed of SrO and Fe₂O₃. Ratios of 1:5.4 to 1:5.8 have been chosen for SrO and Fe₂O₃. As additives, We used 1wt%, 2 wt% and 3 wt% of Al₂O₃. Sintering was carried out at 1250℃ . From experiments on the magnetic properites of specimen, the results are as follows; 1) For SrO : Fe₂Op3 = 1 : 5.4 and 1 : 5.8, we got similar coercivity and residual flux density, but for 1 : 5.6, decrease sharply. 2) For the additive Al₂O₃, coercivity is increased and residual flux density is decreased with Al₂O₃ respectively. Good basic composition region of nonstoichiometric Sr-ferrite has been appeared on the n=5.4 and n=5.8, but in the case of Al₂O₃ addition, We have confirmed good magnetic properties on the n=5.8.
