A 51-year-old man had small, tender, skin colored firm nodule on the helix of the both ears for eight months. He was found to have classic features of chondrodermatitis nodularis chronica helicis, namely, tender nodule less than 1 cm in length with central crusting, localization to helix, age, men, and histologic findings. The histologic examination of the biopsy specimen showed the presence of thinned epiderrnis on center. acanthosis on the adjacent epidermis, with hyperkeratosis and parakeratosis, and cleft between epidermis and dermis. In the dermis, highly vascularized connective tissue and chronic inflarnmatory infiltrate were visible with perichondrial fibrosis. Elastic tissue stain showed degeneration of elastic fibers. After complete excision, no recurrence was obsered until now.

A 51-year-old female had disseminated, symmetrically distributed, brownish black pigmentation and papillary hypertrophy on the intertriginous and flexural areas for 6 months, and gastric adenocarcinoma was confirmed during the evaluation of internal malignancy, The cutaneous finding of acanthosis nigricans was a significant cutaneous marker of internal malignancy in this case.

One patient is a 6-year old female, who has had intensely pruritic linear papuloplaque.", on the left side of the perineal and perianal areas for three years. The other patient, is a. 23-year old male, who has had iritensely pruritic linear papuloplagues on the left upper extremity. This condition started at 1 month of life. In both cases, microscopie examination of the lesions showed psoriasiform and eczematoid appearance. In the latter case, spongioform pustule and Munro's microabscess were also found. We believe that these cases probably represent instances of the entity that. Altman and Mehregan have called inflammatory linear verrueous epidermal nevus, and unusual clinical feature in our patients was the involvement of the left groin in case 1 and of the left upper extremity in case II, which are somewhat rare sites of involvement.

Zinc sulfate, which was used as zinc sulfate ophthalmic solution in herpetic keratitis, has been found to have the therapeutic effects in cutaneous and mucosal herpes simplex. We studied ta evaluate the therapeutic effect of zinc sulfate in patients with herpes simplex. Nine patients with primary herpes simplex and twenty five patient with recurrent herpes simplex were included in this study. Twenty five patients(six with primary type and nineteen with recurrent type were treated with topical applicatiion of 0.3% zinc sulfate solutiion seven to eight times a day and nine patients(three with primary type and six with recurrent type)were applied with placebo vehicle in the same way. Maintenance treatment was then given tc all these patients, first once a week for one month, and then twice a month indefinitely. The effect was assessed by the comparison of the duration of disappearance of symptoms, drying of vesicles and crust formation, and desiccation and sloughing-off of cursts, and recurrence rate between zine sulfat,e group and placebo group. The resuilts were summarized as follows : 1. In the average time of the disappearance of symptoms, drying of vesicles and crust formation, a,nd desiccation and sloughing-off of crusts, the resu1t observecl in zinc, sulfate group was shorter than that of placebo group, respectively ( p < 0.01). 2. In recurrence rate, 11.1% observed in zinc sulfate group was much lower than 80.0%i in placebo group(p . 0.01). These findings suggest that topical zinc sulfate is an effective agent for treatment and prevention of recurrence af herpes simplex infection.

We presented a case of Ehlers-Danlos syndrome(ED syndrome) in s 21-year- old male, who had hyperextensibility of skin, skin fragility, and cigarette paperlike atrophic scars with no joint problems since infancy. There was a family history which was suggestive of autosomal dominant trait. Microscopic examination of the skin biopsy specimen from the normal appearing skin on the right forearm showed no abnormal appearance. In this case the manifestations of skin including marked hyperextensibility might be in accord with type I (gravis) ED syndrome, but the joint manifestation did not correspond to this type. It might be hard to classify this case according to the eleven types of ED syndrome. Wed rather consider this case as a. mixed form of type I and type Il ED syndrome.

6.Dose-Response Curves of Mouse Jejunal Crypt Cells by Multifrationated Irrdiation.
Journal of the Korean Society for Therapeutic Radiology 1986;4(2):89-98
Using as assay for jejunal crypt stem cell survival, dose-response curves for the reproductive capacity of crypt stem cells mouse jejunum exposed to multifractionated gamma-ray irradiation(single, 2, 3, 4, 5, 6, 7, 8, 10,12, and 16 fractions) were analyzed and single-dose survival curve of these cells was constructed. The following conclusion were drawn: 1) Survival curves for higher numbers of dose fractions were displaced to higher dose, and characterized by increasingly shallower slopes. 2) The single-dose survival curve had broad shoulder, Dq=460 cGy, remaining near-exponential over initial dose range 0 to 300 cGy, with initial slope 1Do=474 cGy 3) At fractionated dose in the range of 180 to 450 cGy, the average recovered dose per fraction interval was approximately 50% of the dose per fraction. 4) The value of a/b ratio by using of linear regression analysis for the reciprocal dose plots was 8.3Gy which lied in the range of 6-14Gy for early-reacting tissues. 5) The linear-quadratic model for dose-response formula offers valid approximations for all doses to be used in radiotherapy, only two parameters to be determined, and considerable convenience in practical applications.

7.The Combined Effect of Adriamycin and Imadiation on the Small Intestinal Villi of Mice.
Journal of the Korean Society for Therapeutic Radiology 1986;4(1):1-14
In order to clarify the effect of radiation on the mouse jejunal crypt cells by combined administration of adriamycin and radiation and also to evaluate the enhancing effect of adriamycin, the authors performed this study by delivering single irradiation of 1,000 to 1,600 rad to the whole abdomen of mice by cobalt-60 teletherapy unit. In combination with adriyamycin treatment groups, the drug was administered as single dose of 10 mg/kg either 2 hours before or 4 hours after graded single dose, 900 to 1,400 rad, of irradiation. The authors studied the quantitative changes of intestinal crypt cells by microcolony survival assay technique and the morphological changes of small intestinal villi by scanning electron microscope in mice following to combined therapy with adriamycin and irradiation. The average number of jejunal crypts per circumference was 130+/-6 in control group. The mean lethal dose(Do) of each irradiation alone and combined therapy groups 2 hours before and 4 hours after irradiation, were 160, 170, and 170 rad in cell survival curves, respectively. The dose effect factor(DEF) of adriamycin in each groups of pre-irradiation and post-irradiation were 1.19 and 1.26, respectively. The conical shaped villi were noted on 1,200 rad in irradiation alone group and 1,000 rad in combined groups. For the proper clinical application we must be careful of the radiation injury to small bowel when the anticancer chemotherapy and radiation injury to small bowel when the anticancer chemotherapy and radiation therapy to the abdomen and pelvic area are used as combined therapeutic modality.

OBJECTIVE: The purposes of this study were to observe the radiographic changes of lumbar facet joints by magnetic resonance imaging (MRI) in conservatively and operatively treated groups of patients with herniated intervertebral disc, and to compare the biomechanical effects to lumbar facet joints according to the treatment methods. METHOD: The patients composed of 20 conservatively treated control group and 40 operatively treated group who had disc herniation at lower lumbar spine. Follow-up MRIs were performed in order to assess the radiographic changes of intervertebral disc and lumbar facet joints, such as disc degeneration, lumbar facet joint angle and tropism in either treatment groups individually. RESULTS: There are significant increase in lumbar facet joint angle in operatvely treated group at the level of both L4/5, right L5/S1 compared to that of conservately treated group, but the disc degeneration and facet joint tropism were not changed after treatment in both groups. There's no relationship between treatment period and each parameters. CONCLUSION: The radiographic biomechanical lumbar facet joint changes on MRI seems to be related to degenerative change of lumbar facet joint in operatively treated group with a lumbar disc herniation. Therefore, careful selection of optimal operation time and criteria would be important.
