1.A study of cosmetic allergy in male patients.
Korean Journal of Allergy 1997;17(1):18-24
We have studied male patients with cosmetic allergy in patch test during 5 years from September, 1982 to August, 1986 (Group A) and during 7 1/2 years from March, 1988 to August, 1995 (Group B). The results are as follows. 1. In Group A, 7 patients were diagnosed as contact allergy due to cosmetics. In Group 13, 30 patients were diagnosed as contact allergy to cosmetics. 2. Sixteen patients were positive to only cosmetic related allergens. Two patients were positive to only their own cosmetic products. Nineteen patients were positive to both cosmetic related allergens and their own cosmetic products. 3. The age of patients with cosmetic allergy ranged from 10 to 70 years with a peak in the fifties. The patients more than 50 years were about 40% of all patients. 4. The most frequently, affected area was face(n=31) followed by neck(n=6) and scalp (n = 6 ). 5. Twenty four patients with cosmetic allergy had eczematous skin lesions. Thirteen patients had pigmented skin lesions and pigmented contact dermatitis was suspected. Two out of 13 patients with pig men ted skin lesions were positive in photopatch test. 6. Cosmetic related allergens showing frequent positive reactions were paraphenylene-aliamine, fragnance mix, balsam of Peru, benzyl salicylate, amerchol L101, oakmoss absolute, musk muskene. 7. Cosmetic products showing frequent positive reactions were skin care products, hair dye, soap, after shave lotion, shampoo and toothpaste. In conclusion, cosmetic allergy in men seems to increase in our society.

BACKGROUND: The wound healing process is impaired or delayed in aged patients. The development of a new wound healing model is needed. Nerve growth factor (NGF) plays a special role in wound healing because NGF is expressed only in proliferating tissues such as wounds. OBJECTIVE: The aim of our study was to develop a wound healing model using a 3-dimensional culture system, raft culture, by comparing the level of NGF expression according to the wound stage after an artificial wound was made to the raft samples. We tried to specifically localize the site of NGF expression both in mRNA and protein level. METHODS: Raft culture using normal human keratinocytes was done and a 2 mm slit wound was made in the center of the raft samples. Raft samples of no wound, 4 d, 7 d, and 9 d after wounding were prepared. In situ RT-PCR and immunohistochemistry were performed to detect and localize NGF expression after making wounds and the addition of substance P (SP). RESULTS: We failed to localize NGF mRNA expression in raft samples by in situ RT-PCR. Immunohistochemistry showed NGF staining throughout the epidermis although a little more dense staining was found in the basal layer. NGF(+) cells tended to increase until 7 d after wounding, but there were no significant differences according to the wounding days. There was `a tendency that the SP(+) group showed more NGF(+) cells than the SP(-) group, but there were no statistical differences. CONCLUSION: We think that our in vitro raft wound model using NGF expression could be used, at least in part, as an objective indicator for wound healing. In our raft model lacking nerve, NGF may not be suitable for representing wound healing process because this model can not reflect the interaction between the skin and the nervous system. Expression of growth factors or cytokines other than NGF need to be applied to our raft culture system.

BACKGROUND: Melanocytes grown in pure monolayer culure lack many of the cellular interactions that exist in vivo. This can be partially overcome by growing melanocytes together with other epidermal cells in skin equivalent models. OBJECTIVE: The objective of the present study was to grow human melanocytes in human epidermis reconstructed on dermal substrates in vitro and to examine their response to UV radiation. METHODS: The skin equivalents were prepared by seeding cultured human keratinocytes together with cultured human melanocytes(in a ratio of 5%) onto de-epidermized dermis. After 7 days of culture, they were exposed to UVB irradiation(total 150m J/cm over 5days). On day 12 of air exposure the sections of the skin equivalents were prepared for histology. The structure of the skin equivalents was studied following staining with hematoxylin and eosin. Melanocytes were characterized by DOPA staining and by immunohistochemistry. RESULTS: Melanocytes were localized singly within the basal layer of the reconstructs. Melanin was also visible both in the melanocytes and in neighboring keratinocytes. There was an increase in melanocyte size and dendricity following UV irradiation. Melanocytes became positive to staining with HMB-45 antibody following UV irradiation. CONCLUSION: Our results indicate that melanocytes grown in reconstructed human epidermis are functional and capable of responding to UV irradiation.

This study examined the roles of the initial level of muscle glycogen content and available substrate on glycogen repletion in muscle. The rats were randomly assigned to normal, starvation and exercise groups. The glycogen content of muscle was lowered by starvation and exercise for the purpose of this experiment. The normal rats remained sedentary in their cage without any restriction of food and water. The exercise and starvation groups were divided each group into two subgroups depending on the degree of stress, i.e. 16 and 64 hours starvation, and 30 minutes and 2 hours exercise loading. All experimental aninals sacrificed 9~10 O'clock in the morning. The glycogen content of gastrocnemius and liver were 0.416+0.0433 and 1.70+0.410gm/100gm wet tissue in normal rats, respectively. The glycogen content of gastrocnemius in stravaton groups was reduced to 83.5 and 75.5% of the values of normal groups by starvation for 16 and 64 hours, respectively. In exercise group, the content of glycogen was reduced to 63.7 and 49.8% of the normal group by 30 minutes and 2 hours exercise loading, respectively, After above exercise loading and forced starvation, glucose, 2.0gm/100gm body weight was ingested, and 2 hours later the glycogen content was determined to evaluate the role of initial level of muscle glycogen content on the repletion in gastrocnemius, and the different amount of glucose, 1.0, 1.5 and 2.0mg/100gm body weight, was given orally, and 2 hours later the glycogen content of gastrocnemius was determined to evaluate the role of available substrate on the glycogen repleted in muscle of the lowest initial glycogen content, and the larger the amount of glucose ingestion, the larger amount of glycogen repletion in muscle. The experiment demonstrates that the reducing level of muscle glycogen and increased amount of available substrate are the important factors for the acceleration of muscle glycogen repletion, and in the aspect of repletion of glycogen, the repletion rate of liver glycogen is 2~5 times faster than that of muscle, whereas there is no difference of repletion rate of liver glycogen between starvation and exercise groups.

Cutaneous leiomyoma is a benign tnmor originating from smooth muscle fibers which are derived from arrector pili muscle, media of blood vessels and dartoic muscle of scrotum, vulvar, or nipple. It is classified into 3 types according to the site of origin, namely pilar leiomyoma, angioleiomyoma and genital leiomyoma. Leiomyoma of the nipple is the less kquent type of cutaneous leiomyoma. We report a case of cutaneous leiomyoma on the nipple in a 53-year-old man.

Twenty-five patients presenting with severe hemorrhage from benign peptic ulcers were randomized to either endoscopic injection sclerosis using a combination of hypertonic saline- epinephrine solution and 5% ethanolamine or to hypertonic-saline epinephrine solution only. Only high risk patients with active bleeding or endoscopic stigmata of recent hemorrhage of ulcers were considered. A median duration of hospital admission and median transfusion requirements between the two types of treated groups were not significant difference. The initial hemestatic effects of HS-E solution injection group(n=l5) or combination of HS- E solution and 5% ethanolamine injection group(n=l0) were 93%, 90% respectively. The rebleeding rate of HS-E solution injection group(n =15) or combination of HS-E solution and 5% ethanolamine injection group(n=10) were 33%, 30%, respectively. So, both HS-E solution therapy group and comination of HS-E solution & 5% ethanolamine injection group were effective in initial hemostasis for bleeding peptic ulcer patients. However, for the further evaluation of therapeutic effect and comparison of rebleeding rate between the two types of therapy, we think that it will be indispensable to collect more cases and to compare with control group.
