Two hundreds fifty seven cases of normal mammogram were analysis for classification of types of breasts.Ranging from 20 to 79 years of age, mean age was 45 years. Two projections, craniocaudal & mediolateral, were used. Age, nutrient condition, familial tendency and hormonal factors influence to breats hisologically. Normalbreats were classified into the standard (9.75%), ductal (71.7%), glandular (6.2%) and atrophic (12.4%) types.Ductal type was further subclassified into intraductal, periductal and mixed types. Atrophic type was susbdividedinto fibrous and fatty, Standard type was observed in younger women, instead of atrophic type was seen in olderage group, especially after menopause. Periductal type was most common (65.4%), Glandular type was mostly intwenty to thirty year group. According to increase of age, gladular or ductal type transformed into atrophic type.

Emphysematous pyelonephritis is a necrotizing renal infections characterized by intrarenal and occasional perirenal gas production. Although uncommon (89 cases in the literature), it occurs almost exclusively in diabetic patients (87% of the cases). Prompt and aggressive management is required to sahage these patients. We describe a recent case of a diabetic woman with emphysematous pyelonephritis due to E. Coll, successfully managed with unilateral nephrectomy.

Cimetidine, an H-histamine receptor antagonist, has been advocated to have enhancing effect on delayed type hypersensitivity. However, some recent reports have caused controversial opinion regarding the effect of cimetidine on delayed type hypersensitivity assessed in vivo. In this study the effect of cimetidine at the various periods of contact sersitivity reaction (CSR) to DNCB was assessed in guinea pigs. Three groups of five guinea pigs were sensitized with DNCB in the nuchal region and challenged with DNCB in the back on 16th day after sensitization, Cimetidine, 300mg/3ml/kg, was injected intraperitoneally once a day for the duration of different periods. For the first group, cimetidine was injected during the first 10 days after sensitization to assess its effect on the preparative and recognition phase of the induction period of CSR, For the second group, cimetidine was injected from the 6th to the 16th day to evaluate the enhancing effect of cimetidine on CSR at the period when suppressor T-cells were considered to be active. For the third group, cimetidine was injected for the last 3 days before elicitation test to assess the effect of short term treatment of cimetidine on the established CSR to DNCB. For the elicitation, two different consentrations of DNCB were applied on the three sites along both sides of the spine in the back. Total means of the degree of CSR elicited by DNCB were significanly ircreased by cimetidine in the second and third groups (p<0.05). These enhancing effects of cimetidine on CSR were more prominent at the uppermost back than other sites, eliclted by 0.05% DNCB rather than 0.01% DNCB.

The patient was 29 years old male who has been suffering from long standing painless multiple brownish red papules and nodules on the left forehead since 10 years previously. Histopathologically, dermal vascular component consisted predominantly of irregularly shaped capillaries with greatly swollen, pleomorphic endothelial cells some of which protruded into the lumen. And many eosinophils and lymphocytic infiltrations were seen in the dermis. Direct immunofluorescence showed homogeneous or granular deposits of C, in the endothelial cell of the small blood vessels in the dermis.

We have encountered a rare case of erythema nodosum-like leukemia cutis associated with acute myelocytic leukemia(AML) in a 57-year-old male. He was in good health until about 2 weeks prior to admission, when the systemic symptoms of high fever, anorexia, general weakness and malaise, and subcutaneous nodules developed. The nodules were multiple, red and noted bilaterally on the pretibial areas. Histological findings of his skin lesions showed diffuse cellular infiltrates intermingled with leukemic cells predominantly involving the adipose tissues. The cells displayed negative stainirig to antibodies CD3 and CD20, but positive staining to LCA. The diagnosis of AML(M4) was made by blood and bone marrow studies. He had a rapid downhill course and was discharged after 2 weeks of admission, with no anti-cancer chemotherapy.

We examined the anatomical position of the mental foramina in mandibles foramen normal adult Koreans. 1. The percentages obtained from the study of the relationships between the mental foramen and the lower teeth showed that the most common location was type lv in which the mental foramen lay at the apex of the second promolar. The foramen between thr apices of ice two premolars (type lll) and the foramen between the second premolar and the first molar (type v) occured often and less often rspectively and find no foramen mesial to the first premolar or at the apex of the first premolar and posterior of the first molar (type l, ll, vl). 2. The study of relationship of the mental foramen to the bo of the mandible revealed that mental foramen was situated closer to the lowed border of the mandibular body. The distance ratio between the mental foramen and the alveolar crest to that between the mental foramen and the lower border was approximately 1.2 : 1. The height of the mandibular body was 31.09±2.80mm on the left side and 30.97±2.48mm on the right. 3. The distance from the mandibular symphysis to the anterior border of the mental foramen measured 29.52±2.01mm on the left, 30.82±2.04mm on the right side, and from the mandibular symphysis to the posterior border of the mandibular ramus was 104.20±4.74mm on the left, 105.44±4.49mm on the right side. It indicates that the mental foramen lies approximately at one-fourth of the distance from the mandibular symphysis to 2017-04-19 the posterior border of the ramus. 4. The distance from the superior border of the mental foramen to the bottom of the lower second premolar socket was found to be positive. It was 5.46±3.09mm on the left, 5.73±3.03mm on the right side. This indicates that the bottom of the lower second premolar socket is slightly higher than the superior border of the mental foramen.

Aspergillus is usually found in the human upper respiratory tract, or soil, and causes sinusitis for the immunocompromised or immunocompetent hosts. Sometimes it extends to the cavernous sinus, internal carotid artery or the orbit and results in severe complications. We diagnosed cavernous sinus thrombosis and sphenoid sinusitis by Aspergillus in a 58-year-old woman who visited our clinic for headache, left eyeball pain, and proptosis. We treated the patient with endoscopic ethmoidectomy, sphenoidectomy and antifungal therapy with Amphotericin B. During one year of follow-up, we found no evidence of recurrence. Cavernous sinus thrombosis by Aspergillus is a rare disease, and can be treated successfully without recurrence with early diagonosis and vigorous treatment.

This study was performed to investigate the clinical efficacy of intralesional recombinant interferon-γ (IFN-γ) in the treatments of warts, using a placebo comparison. Warts of each groups were injected with INF-γ containing 5×10⁶ IU/ml (high dose), 1×10⁶ IU/ml (low dose), or distilled water for injection as placebo, respectively, twice weekly for three weeks. The final therapeutic efficacy was determined on the fourth week after the beginning of therapy. Among the 74 patients with periungual warts, plantar warts, or warts of other sites, complete clearing of the treated warts at week four occurred in 56% of the 36 patients receiving the high dose IFN-γ compared to 30% of the 53 receiving the low dose IFN-γ and 17% of the 36 receiving the placebo. Marked improvement showing 75% or greater regression of wart lesions was noted as 89% of patients receiving the high dose INE compared with 55% receiving the low dose IFN and 50% receiving the placebo. The group of patients with warts of other sites showed the best response. The group receiving the high dose IFN experienced some adverse effects more frequently or more severely than the group receiving low dose IFN. However, the effects were relatively tolerable to the patients. Therefore, intralesional injection of the high dose IFN-γ may be more useful in treating warts than a low dose IFN-γ.
