The health-promoting qualities of ultraviolet light have been well recognized, but it also induces deleterious effects from sunburn to skin cancer, Since our enviroment exposes us to both ultraviolet and infrared rays at the same time, the latter is considered to influence to some extent the cutaneous effects of the former. In recent years, it has become increasingly apparent that the biologic effects of one type of radiation may be modified by wavelengths of different energies. Interactions of this kind are complex and occasionally result in true synergy or antagonism. Although there are several reports on these interactions, the results are not in accordance. This study was undertaken to investigate the influence of infrared radiation (IR) on ultraviolet radiation (UVR)-induced skin injury, especially minimal erythema dose (MED). Thirty-five healthy medical students participated in this study between May and June, 1983. One side of the back was exposed to IR with UVR while as a control the other side was exposed only to VVR. The results were summarized as follows : 1. In one experiment treated with IR before UVR, the mean MED-S.D. of the treated site was 17 7+5 3 (sec) and that of the control site was 18. 3-+6. 4 (sec)- The increase of the MED was statistically significant. (p<0. 01], paired t-test) Among the fifteen subjects, the MED was increased in 73% (11/15), and the same in 27% (4/15).

One of the most common symptoms in gynecologic disorders is an abnormal utirine bleeding, of which dysfuncyional uterine bleeding (DUB) is frequently encountered. DUB is defined as an endocrinologic imbalance of the axis of hypothalamus-pituitary-ovary-endometrium without organic diseases such as a neoplasm, and inflammation, a pregnancy, a trauma, Although the correct diagnosis of DUB depends on various assessements such as a menstrual cycle, basal body temperature, endocrine assay, vaginal cytology and endometrial histology, in many circumstances pathologist have only the endometrial histology with trivial clinical information to make a diagnosis. Therefore, the present study was aimed at assessing the pattern of the endometrium as precisely as possible. The histologic pattern was classified according to the Handrickson and kempson classification (1980). The authors also attempted to correlate the non-neoplastic metaplasia with the endometrial histology. The material consisted of 447 cases of endometrial curettage specimens diagnosed clinically as DUB during recent 4 years. The histologic examination was carried out through the routine formalin fixed-paraffin embedding method, followed by hematoxylin-eosin staining in routine and other special staining as required. The following results were obtained; 1) The pattern of the endometrium in DUB was predominently the proliferative type (239 cases, 65.55%). Of these 293 cases, 144 were of the abnormal proliferatrive phase, and particulary most were the disordered proliferative phase. The remaining 154 cases (34.45%) were found to have secretory endometrium, of which 50 cases belonged to the abnormal secretory type. Most of the cases shewing abnormal secretory patterns appeared dyssynchronous or underdeveloped. 2) Of the 361 patients with DUB for whom the clinical records were available, 197 (54.57%) were non-ovulatory and 118 (32.69%) were ovulatory. 3) Non-neoplasic metaplasia was found in 87 cases, of which ciliiated and papillary types were most common. The endometrium was of the proliferative phase in 73.56% of the cases with metaplasia, and the disordered proliferative pattern showed a particular correlation with the metaplasia (44 cases). 4) Among 63 postmenopausal DUB patients, 52 (82.53%) appeared to have the proliferative endometrium, and in particular 23 (36.51%) had the disordered proliferative endometrium.

PURPOSE: Benign prostate hyperplasia(BPH) can be treated with alpha1-adrenergic blocker that relaxes prostate smooth muscle or 5 alpha-reductase inhibitor that reduces serum dirtydrotestosterone. The efficacy of the combination of 5 alpha -reductase inhibitor(finasteride) and alpha1-adrenergic blocker(doxazosin) was evaluated in patients with benign prostate hyperplasia. MATERIALS AND METHODS: Eighty five patients with BPH was treated and followed over 6 months and divided into three groups: Group 1(doxazosin 3mg/day), Group 2(finasteride 5mg) and Group 3(combination of both drugs). Initially, all patients were evaluated by international Prostatic Symptom Score(IPSS: irritative, obstructive, sum, life quality), uroflowmetry, residual urine, serum prostate specific antigen(PSA) and prostate weight by transrectal ultrasonography. IPSS, uroflowmetry and complications were evaluated every month. Residual urine and PSA were assessed at every 3 months, prostate weight at every 6 months. RESULTS: In Group 1 and 3, IPSS were more decreased than In Group 2 immediately(p < 0.001). In Group 1 and 3, maximal flow rate was more increased than in group 2 immediately(p < 0.001). There was no difference of mean change of residual urine among three group. In Group 2 and 3, serum prostate specific antigen and prostate weight were more decreased than in Group 1 (p < 0.001). CONCLUSIONS: In medical treatment of BPH, the combination therapy of alpha1-adrenergic blocker and 5alpha-reductase inhibitor shows early symptomatic improvement and decreased prostate weight without significant complications.

We reviewed the 43 medical records of patients with cellulitis or erysipelas who had been admitted at the depar1ment of dermatology of Seoul National University Hospital and followed them up for mean 21.6 months. The results were as follows. 1. The sex ratio of patients with cellulitis was 1:1.4 and the average age was 49 years. 2. The lower extremity as the most frequently invloved site of cellulitis with the frequency of 58.1% (25 cases), with the head and neck being involved in 16 cases(37.2%) and trunk and upper extremity in 1 case each(2.3% ). 3. The portals of infecticin were suspected in 33 cases(76% ), where tinea pedis was detect,ed in 18 cases(41.9%), previous skin infeection 10 cases(23.3%) and trauma in 9 cases(20.9%). 4. Initial systemic symptoms were fever(76.7%), chill(65.1%) and headache(37.2%). Erythema(100%), local heating(90,7%), tenderness(88.4%), swelling(86.0%), ulcer(16.3%), bulla(14.0%), lymphangitis(9.2%) and lymphadenit,is(9.2%) were found in the skin lesions. 5. The laboratory findings revealed leukocytosis in 35.7%, elevaed ESR in 86.8% positive 6. ASO titer in 63.0% and positive CRP in 80%, Microorganism. were detected in only 1 of 15 blood cultures, in 2 of 4 bulla fluid cultures and in 7 of 9 bus cultures. There was no growth of causative microorganisms in 3 tissue cultures and 9 saline needle aspiration cultures. Penicillin was used as primary antibiotics in 19 cases, which changed to another antibiotics due to lack of improvement in 3 cases and cefazolin was used in 21 cases, which changed in 2 cases due to the same reason. 7. Average admission priod was 11 days(range from 3 to 20 days) and 30.2% of patients wit.h cellulitis experienced recurrence, but 48% on low extrernity in contrast with 6.7% on head and neck.

There are considerable discrepacies between clinical symptoms and imaging diagnosis in the localization of the responsible radiculopathy. The purposes of this study are to analyzed the dynamic alteration of contrast filling of the spinal nerve sleeves during positional changes and to determine how the abnormalities of nerve sleeves no lateral bending A-P views correlate with sciatica. The criteria indicationg the root abnormality in functional myelography were (1) bad filling of ipsilateral root to sciatica and (2) good filling of contralateral root compared with those in neutral A-P view. Of total 77 patients, 67 had radiculopathy and 10 had no radiculopathy. In 23 (34.3%) of 67 patients with radiculopathy and 6 (60%) of 10 patients with no radiculopathy, their clinical symptoms well correlated with conventional myelographic findings. However, in 35 (52.2%) of 67 patients with radiculopathy and 6(60%) of 10 patients with no radiculopathy, their symptoms well correlated with functional myelographic findings. This study suggests that the functional myelogaphy using both lateral bending A-P views can be used as a complementary tool in the evaluation of the radiculopathy.

The present study was performed in order to investigate the correlation among the number of T zone histiocytes, the clinicopathologic parameters and the patient's survival. The subjects in this study were 131 advanced gastric carcinomas including 86 follow-up cases and 41 early gastric carcinomas. The infiltration of T zone histiocytes into tumor tissues was investigated using the immunohistochemical method with andti s-100 protein, nd the data obtained were evaluated statistically. T zone histiocytes were scattered among the cancer cells and in areas formed clusters within the cancer stroma. These cells were abundantly present in tumor tissues and around lymphoid follicles but were rarely seen in surrounding normal stomach tissue. Analysis of the number of T zone histiocytes showed no correlation between the number of T zone histiocytes and the clinicopathologic features except the degree of lymphocytic infiltration within the advanced and the early gastric carcinomas. Survival of the patients with a marked infiltration of T zone histiocytes in stage III was longer than that with mild infiltration of T zone histiocytes, but there was no statistical significance(P value=0.084). Multivariate regressio analysis revealed that the depth of invasion(P value=0.0074) and the lymphocytic infiltration(P value=0.0152) were the important prognostic factors. The results indicate that good prognosis is expected in cases with less deep invasion and high lymphocytic infiltration, and that the number of T zone histiocytes is in proportio to the degree of lymphocyte infiltration within the tumor, although not directly correlated with the patient's survival.

PURPOSE: To analyze the MR imaging features of multiple sclerosis (MS) in spinal cord. MATERIALS AND METHODS: Nine MR (magnetic resonance) images of six patients with suspected MS were retrospectively evaluated in active phase (n=6) and inactive phase (n=3) before and after Gadolinium-DTPA administration. RESULTS: In all patients with clinically active phase, plaques of spinal cord appeared as high signal intensity on T2-weighted image with isointense cord swelling on Tl-weighted images. All lesions were enhanced on Gd-DTPA enhanced Tl-weighted images. The patterns of enhancement were nodular, circumferential rim-like, and segmental. On follow-up images in 3 patients who became clinically stable, all enhancing lesions disappeared. CONCLUSION: MR is a good modality in detection of spinal MS, and Gd-DTPA-enhanced MR is valuable in differentiating active MS from stable MS.
