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.

Cutis verticis gyrata(CVG) is an unusual conformation of the scap characterized by the presence of folds and furrows due to thickening of the corium and the subutlneous tissue. In sccordance with etiological factor and associated findings, CVG occurs as primarary disease or secondary to a variety of local or systemic diseases. Cerebriform intradermal nevus(CIN) is a cause of CVG that can usually be recognized clinically and for a certainty histologically. We report two cases of CVG due to CIN. Not only did they have CVG due to CIN on the scalp, but also they had associated congenital nevi on the face and whole boispy, respectively.

Most subdural hematoma with significantly differed attenuation from that of adjacent brain tissue can beaccurately diagnosed by CT. Difficulty arises when the hematoma is isodense that is exhibited similar attenuationto that of brain. Unilateral isodense subdural hematoma can be identified by indirect sign such as mass effect.Occasionally, the use of intravenous contrast material to aid in identifying isodense subdural hematomas has metwith variable success. Moreover, bilateral isodense subdural hematoma may be more difficult. We therfore considerdit of interest to evalute the diagnostic efficiency of CT in isodense subdural hematomas. We have analysed 13cases surgically provened cases of isodense subdural hematoma examined at Korea General Hospital from Oct. 1981 toApril. 1982. The resuls were as follows; 1. One hundred twenty seven cases of subdural hematomas were studied byCT, 13 cases (19.2%) of which were isodense. 2. The age distribution was from 29 years to 69 years and mean agewas 52 years. The sex ratio was 11 male to 2 female. 3. Seven(53.8%) of 13 cases has a history of head trauma. 4.The time interval which subdural hematoma became isodense was from 1 week to 4 months and peak time interval wasfrom 1 week to 3 weeks. 5. The precontrast CT of isodense subdural hematoma appeared shifting of midlinestructure, compression and deformity of the ventricles in all 13 cases, effacement of cerebral sulci in 10 cases(76.9%) and dilatation of contralateral ventricles in 4 cases (30.8%). 6. The postcontrast CT scan demonstratedenhancement of the medial margin of the lesion in 4(30.8%) of 13 cases and displacement of cortical vein away fromthe inner table of the skull in 3 (23.1%) of 13 cases. 7. Bilateral isodense subdural hematomas were 2 (15.4%) of13 cases.

CT findings of seventy seven cases in sixty six patients were compared with the conventional radiographicfindings to evaluate the utility and the merits of the high resolusin CT in trauma, The resuls were as follows: 1.CT was helpful in the management in 50 cases(64%) of total 77 cases. 2. CT was useful in detection and evaluationof traumatic lesion in shoulder, wrist and ankle as well as spine, pelvis, hip and knee. 3. In difficultdiagnostic dilemas in trauma of the bones and the joints with the complex anatomy, CT should be consideredroutinely when appropriate.

PURPOSE: We examined the ability of alpha-phenyl-tert-butyl-nitrone (PBN), an electron spin trapper, to determine the neuroprotective effect in the argon laser induced ischemic rat retina model. METHODS: After ischemic condition of rat retina was induced by argon green laser, PBN was given intraperitoneally at 50 or 100 mg/kg and normal saline was injected to control group. After 24 hours, 48 hours, and 7 days, the neuroprotective effect of PBN was examined by electroretinogram (ERG) and after 7 days, the enucleation of eyes was performed and histologic findings were compared by light microscopy and transmission electron microscopy. RESULTS: We found relatively reduced amplitude of ERG wave in the PBN injected group but not so greatly reduced as in normal saline control group. The retinal ganglion cell (RGC) layer and the number of RGCs were affected by acute ischemic changes but in the group of PBN treatment, the cell membrane was well preserved and vecuoles formation, cytoplasmic destructions, nuclear chromatin condensation were reduced. CONCLUSIONS: Systemic administration of PBN can ameliorate an argon laser induced retinal ischemia. Further investigations are necessary to decide effective dose without toxicity and to find more convenient methods of administrations.

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.
