We roport herein three cases of pruritic urticarial papules and plaques of pregnancy in two primigravidas and one multigravida in erythematous papules and urticarial plaques on both thighs, buttock and upper extremites. In the second case, lesions initially developed on both thighs and then preaded on abdomen, back and exter ities. Abdomen, thighs and extremites were involved in the third case. Histopathologic findings revealed acanthosis orfocal spongiosis in epidermis and lymphocytic perivascular infiltration with or without eosinophilsn dermis. They were treated with systemiror topical steroids and, mtihistamines. Itching was relieved within a few days after therapy and skin lesions resolved spontaneously after delivery.

Baboon syndrome is used to denote a systemic allergic contact dermititis with a characteristic color and distribution pattern. It is also referred to as mercury exanthem, because inhalation of mercury vapor usually causes the skiri lesion in a sensitized person. Diffuse pi,ikish erythema of the buttock, upper inner thigh, and axilla are characteristic features. We report a case of baboon syndrome developed after exposure to the smoke of a burning amulete a charm written on a piece of paper in a 12 year-old female. Mercury sensitivity was confirrned by a patch test. Atomic absorption by a spectrographic method and Scanning electron microscopy/energy dispersive for analysis X-ray detected mercury in the urine and the ed scraped pigments from the amulet, respectively.

The purpose of this study was to compare the accuracy of currently used elastomeric impression materials for complete arch impression taking. Five elastomers (Impregum, Permlastic, Express, Extrude, Examix) and one Irreversible hydrocolloid (Aroma-fine) were tested. For each material, 5 impressions were made of stainless steel model to which five tapered posts were attached. Custom trays were used for polyether and polysulfide impression materials, and putty/wash two step technique was used for addition polyvinylsiloxane impression materials. Improved stone models were poured to all impressions. Accuracy of the materials was assessed by measuring ten distances on stone dies poured from impressions of the master model. All measurements for master and improved stone models were with three dimensional measuring machine. The results were as follows 1. The dimensional accuracy of polyether, extrude, and examix were significantly superior to polysulfide, exress, and alginate in reproducing full arch mode (p<0.05). 2. There were no statistical differences in dimensional accuracy for full arch impression between polyether, extrude and examix (p>0.05). 3. there were no statistical differences in dimensional accuracy between polysulfide, express, and alginate (p>0.05). 4. There were no statistical differences between addition polyvinyl siloxane materials (p>0.05). 5. There were no statistical differences between anterior-posterior and lateral dimensional changes of all impression materials (p>0.05).

In situ hybridization (ISH) is a standard method for localizing DNA or RNA sequences in tissue or cell preperation. The technique was developed at the electron-microscopic level, and enables the precise subcellular localization. A method was developed for detection of specific viral DNA. We have tested various methods and technique to detect specific viral DNA through ISH at the electron microscopic level. Postembedding method of ultrastructural ISH was developed and successfully applied for the detection of human papillomavirus type 16 in squamous cell carcinoma of the uterine cervix and Epstein-Barr virus in EBV-infected leukemia cell line. The following results are made. The best results were obtained using 0.2% glutaraldehyde and 4% paraformaldehyde fixed tissue or cell block. The labelling was best observed on Unicryl resin and Lowicryl K4M resin sections. Epon sections showed no reactivity. Thin sections of Unicryl resin were more easier than Lowicryl K4M resin. Enzymatic predigestion with proteinase K, pepsin and trypsind gave good results. However, high concentration of these produce poor results due to excessive destruction of the cellular components. Alkali treatment with 0.5N sodium hydroxide produced successful results in denaturation of target DNA. The labelling density of gold particles was independent of incubation time or temperature in hybridization step. The viral DNA labelling was localized mainly within the nucleus, both within and at the edge of electron dense regions, and below the nuclear membrane. And the labelling was seen in the form of a dense, roughly spherical shape. In conclusion, the best results are obtained by the conditions that tissue fixed by 0.2% glutaraldehyde and 4% paraformaldehyde solution, embedded with Unicryl resin, protein denaturation by 0.1ul/ml proteinase K, DNA denaturation by 0.5N sodium hydroxide, and reaction with DNA probe.

Plaster of Paris is an effective ancillary treatment in the surgery of infected cavities in bone. It is well tolerated and spontaneously absorbed over the period of weeks to months, being replaced by bone of normal architecture. When the antibiotics incorporated into plaster of Paris, the antibiotics are capable of prolonged local release in bactericidal concentrations. Therefore it is proposed that antibiotics loaded plaster of Paris might be a simple adjuvant technique after good surgical debridement for the treatment of bone infection. The authors carried out an experiment to study the effect of plaster of Paris containing antibiotics for a prevention of experimental osteomyelitis, using 45 rats, which were divided into 3 groups. In the Group 1, a defect was made at the proximal metaphysis of the tibia, inoculated by Staphylococcus aureus sensitive to Cephradine and Tobramycin and then filled with plaster of Paris pellet. In the Group 2, a defect was filled with Cephradine loaded plaster of Paris pellet. In the Group 3, a defect was filled with Tobramycin loaded plaster of Paris pellet. Then we observed the healing process of the bone defect in the point of view of the gross findings, radiologic findings and histologic findings at 4th, 8th and 12th week after operation. The results of this study were as follows:l. In the control Group;all 30 cases were infected. 2. In the Group 2;only 4 of 30 cases were infected. 3. In the Group 3;all 30 cases were not infected. 4. The plaster of Paris filled into the defect was absorbed continuously and stimulated the new bone formation.

This study was performed to fine out the possible causes of primary infertility in female and to provide some diagnostic and therapeutic modalities. A total of 104 cases of endometrium in primary infertility was obtained from the pathology files of Chosun University Hospital and Kwang-ju Christian Hospital during the period of 5 years and 10 months from January, 1984 to October, 1989. The endometrial biopsies were taken on the first of menstruation and classified according to Noyes, Hertig and Rock's criteria. Histologic findings which were compatible with their normal menstrual cycle (premenstrual of late secretory phase and bleeding phase) were noted in 52 cases (50%). Abnormal 52 cases (50%) revealed deficient secretory phase in 36 case (34.6%), proliferative phase in 5 cases (4.8%), irregular proliferation and chronic nonspecific endometritis in 4 cases (3.8%), respectively, endometrial hyperplasia in 3 cases (2.9%), tuberculous endometritis in 2 cases (1.9%), and asynchronous cycle in 1 case (1%). Among the case of dissociated delay was 21 cases (20.2%) and coordinated delay was 15 cases (14.4%). Therefore, deficient secretory phase with dissociate delay was most common abnormal endometrial finding in cases of female primary infertility. The peak age distribution of the female primary infertility in this study revealed 73 cases (63.8%) in patients between the age of 25 and 29. This finding indicated that there was no significant relationship between the age distributions and the endometrial histopathologic findings.

Endometrium of early pregnancy were compared with nonpregnant endometnum by inimunohistochemical and ultrastructural techniques with respect to glandular and stromal elements of endometrium. The results obtained were as follows: 1. The AS cell in decidua has all the features of actively secreting glandular epithelium and shows the pronounced arrays of glandular endoplasmic reticulum and moderate numbers of ribosomes ultrastructually. Therefore the AS cell indicate considerable protein production, presumably contributing to both cell gowth and the production of secretions. 2. The process of decidualization can be characterized morphologically and immunohistochemically by the accumulation of basement membrane-like materials, such as laminin and type IV collagen which may be related to the hormonal stimulation occuring during pregnancy and trophoblastic attachment. 3. The decidual cells show strong positive for vimentin and some large mature decidual cells show weakly positive for lysozyme and cti- antitrypsin, which might represent more the sequential differentiation of stromal cells into decidual cells than origin of histiocytes. 4. Immunoreactivity with S-100 protein was found in glandular and stromal cells of decidua but negative in endometrium of nonpregnant women. So some humoral factors related to pregnancy stimulate expression of S-100 protein in glandular and stromal cells of decidua.
