The author evaluated the optimal concentration of 3 compositions of TIC medium which has used as the melanacytes culture medium. The concentrations of placental extract and bovine pituitary extract, which have the ability to promote proliferation of melanocytes, were evaluated also. Modified TIC medium with above 5 components of evaluated concentration was very effective in melanocytes culture. The results were as follows : l. 12-0-tetradecanoyl-phorbol-13-acetate (TPA) showed effective melanocytes proliferating activity at the concentration of 30ngml (p(0.05) 2. Isobutylmet:hyl xanthine (IBMX) showed effective melanocytes proliferating activity at the concentration of 0.3mM (p(0.05) 3. Cholera toxin (CT) showed effective melanocytes proliferating activity at the concentration of )OnM (p(0.05) 4. Two percentages of placental extract in culture medium showed effective melanocytes proliferating activity. S. Two percentages of bovine pituitary extract in culture medium showed effective melanocytes proliferating activity. 6. Placental extract and isobutylmethyl xanthine proved to have high melanocytes proliferating activity. 7. Melanocytes proliferated rapidly on modified TIC medium (Proliferation doubling time . about 43 hours) 8. The peak time of melanocytes proliferation (7.2 X 10/cm) was observed on the seventh day of culture, From this data, this culture system can be recommended as a new melanocytes culture.

In humans, the major stimulus for cutaneous pigmentation is ultraviolet radiation. Little is known about the mechanism underlying this response, in part, because of the complexity of the interactions involving the whole epidermis. The present stucy was undertake to evaluate the effects of a single exposure of UVB on cultured normal melanocytes. Melanocytes were exposed to UVB from 5.1 mJ/cm to 203 mJ/cm. The results were as follows : 1. The main morphologic changes in UVB-exposed groups w re larger sized cells, more blunted dendrites, and shorter dendrites than in the control group. These cells increased sized according to the increased doses of VVB, but above 101.5 mJ/cm, the melanocytes shrunk and were destroyed. 2. From 20.3 mJ/cm of UVB, the proliferation of melanocyte was decreased, Especially, there was statistical!y significant difference above 50.8 mJ/cm (p<0.05, p<0.01). 3. The antiproliferativo effect increased with the passage of tirie after UVB exposure. So, cell count could not be done in 101.5 mJ/cm and 203 mJ/cm on the third day, and in 50.8 mJ/cm, 101.5 m J/cm and 203 mJ/cm on the seventh day. 4. Statistically the melanin content per well was significantl dicreased to 11-28% of each control group with dose above 50.8 mJ/cm (p<0.05, p<0.01). The melanin content per cell was increased to 107-128% of each control group when doses were below 20.3 mJ/cm and decreased to 49-79% of each control group when above 0.8 mJ/cm on the third day, but there was no statistically significant difference. In summary, when melarocytes were exposed to UVB, morphclogic changes progressed to cell differentiation. The results also suggested that a low or dose of UVB has an antiproliferative arid mild melanogenic effect, and a higher dose of UVB has a direct cytotoxic effect.

Latency within the nervous system is a characteristic feature of herpesviridae infection. It is reactivated by triggering factors such as UV exposure, stress, and trauma. Simultaneous reactivation of herpes simplex and herpes zoster is uncommon, however, an observation provably explained by differences in the trigerring mechanism. Concurrent reactivation of herpes simplex virus (HSV) and varicella zoster virus (VZV) is occasionally encountered in immunosuppressed patients; on the other hand, it is rarely reported in immunocompetent individuals. We present the case of an immunocompetent 8-yr-old female patient with concurrent reactivation of HSV on the face and VZV on the right L2 dermatome.

Postictal sequential serum prolactin concentrations were observed in 28 patients with various type of seizures who were hospitalized at Keimyung University Hospital. Of 28 epileptic patients, 18 male and 10 female, age ranged from 18 years to 79 years (mean 42 years), 15 with generalized seizures, 13 with focal seizures (5 with simple partial seizures and 8 with partial seizures with generalization). Symptomatic epilepsy and epileptic patients with factors which may affect serum prolactin concentrations were excluded in this study. Serum prolactin concentrations were measure at 15, 30 and 60 minutes after convulsion and 24 hours after convulsion for the base line serum prolactin level. Patients with generalized seizsures and significant elevation of serum prolactin concentrations at 15, 30 and 60 minutes after ictus (Table 1). Same results were obtained in patients with simple partial seizures at 30 minutes and 60 minutes after ictus, and 15 minutes and 30 minutes after ictus in patients with partial seizures with secondary generalization (Table 2 and 3). Level of serum prolactin concentrations were higher in patients with generalized seizure than the other type of seizures. Therefore, measuring serum prolactin level could help differentiate postictal state and other causes of mental change, and also differentiative various type of seizures.

BACKGROUND: This study used MDS-HC 2.0 (Minimum Data Set-Home Care) to analyze the health and the state of function of the traveling health objects. This study was intended to make use of it with the basic materials for providing them with traveling health service suited for the requirement on the health of the traveling health objects. METHODS: The subjects of this study were 1160 people (over 65 years) living under management control of local Health Center from September 7th to October 3th, 2006. This study was analyzed with inter RAI program & SPSS/WIN 10.0, chi-square -test, t-test, and ANOVA. RESULTS: The result showed that 8.97 CAPs per an elderly person was identified and the subjects over 60% had an injury problem from a fall, health prevention service, vision, IADL, pain, and cognition. The number of CAPs in general was high in higher age and the less educated, and those without a job. But, in subjects that had a life partner and a spouse, the number of CAPs was low. In CAPs by the distinction of sex, CAPs which was much more in man than women in statistics were the improvement of health, the abuse of alcohol and drinking wine, bedsore, and the weak supply system. CAPs which women had much more were the function of the heart and the lungs, pain, the performance of the doctor's advice, health prevention service, and incontinence of urine and insertion of catheter. According to the results comparing CAPs by the level of the ADL, the number of CAPs was shown that the group of ADL 2 was higher than group ADL 1. The matter in which the traveling health service had to be applied in all both ADL1 and ADL2 was injury from a fall, health prevention service, and vision. Conculsion: MDS-HC is applicable to decide the care needs for health and social service supplies. The results can be further applicable for careplan, and referral criteria in continuum of care service over long-term care spectrums.

The authors investigsted the effects of azelaic acid on human melanoma cells (G 361 melanoma cell line) and cultured normal melanocytes obtained from the prepuce of newborn. The results were as follows : 1. The proliferation of melanoma cells was decreased, but not in a dose-and time- ependent fashion. The cell population of melanoma cells after 2, 4, and 6 days of culture was decreased to 3.80 x 10(5)cells/well, 4.55 x 10(5)cells/well, and 4.30 X 10(5)cells/ well, respectively, in the presence of 10(-2)M azelaic acid. The proliferation of mormal elanocytes of normal melanocytes was decreased in a dose-dependent, but not in a time-dependent fashion. The cell population of normal melanocytes after 2, 4, and 6 days of culture was significantly decreased to 6.38 x 10(5)+/-1.37 x 10(5) cells/well, 5.33 x 10(5)+/-0.73x10(5) cells/well, and 7.20x10(5)+/-1,11 x10(5)cells/well, respectively, in the presence of 10(-2) M azelaic acid(p<0,05, p<0.01). 2. A dose-and time-dependent inhibition of DNA synthesis was not found in either group. However, DNA synthesis in melanoma cells was decreased to 92710+5188 CPM, 16268+/-15S5 CPM, 8518+/-996 CPM, respectively, after 2, 4, and 6 days of culture, and in normal melanocytes was decreased to 9398+/-2279 CPM(p>0.05) and 6953+/-1217 CPM (p<0.05) after 4 and 6 days of culture in the prensence of 10(-2) Mazelaic acid, 3. There was no difference in melanin content per well at various concentrations in either group, but the melanin content per individual melanocyte of the melanoma cells was increased to 0.0303 ng/cell, 0.0253 ng/cell, and 0.0377 ng/cell, respectively, and that of normal melanocytes was signifieantly increased to 0.0754+/-0.0215 ng/cell, 0.0719+/-0.0144 ng/cell(p<0.05), and 0.1089+/-0.0185 ng/cell(p<0.05), respectively, after 2, 4, and 6 days of culture in the presence of 10(-2) M azelaic acid.

BACKGROUND: The combination of psoralen and UVA (PUVA) as a model of photochemotherap, has been used in a wicle variety of cutaneous disorders such as psoriasis, vitiligo, mycosis fungoides and atopic dermatitis. The mechanism of PUVA of psoriasis is based on the fact. that PUVA causes photoconjugation of psoralens to DNA and a subsequent suppression of mitosis, DNA synthesis, and keratinocyte proliferation. Although PUVA apparently inhibits keratinocytie proliferation and is effective therefore in the treatment of psoriasis, PUVA increases pigmentations by stimulating melanocyte proliferation and melanin synthesis in vivo. OBJECTIVE: We tried to investigate the PUVA effects on the proliferation and different,iation in cultured human keratinoc tes and melanocytes. METHODS: We examined morphologic changes, and the number of the cultured human keratinocytes and melanoiytes and melanin contents in a control group and experimental group. (UVA group, 8-MOP group and PUVA group). i.e., UVA group was exposed to UVA at 60mJ, of. 8-MOP group was acJded at dose of 2 x 10 M to medium for 30 minutes. PUVA group was exposed to UVA at 60mJ, of after adding in 8 MOP at Zx 10 M for 30 minutes. RESULTS: 1. Morphologic changes of cultured human keratinocytes and melanocytes. There were no significent changes between the control group and the experimental groups in keratinocytes and melanocytes after 24, 48 and 72 hours culture. The number and length of meianocyte dendrites showecl no significant differences between the groups after 24, 48 and 72 hours culture(p>0.05). 2. Proliferation of cultured human keratinocytes and melanocytes 1) The number of keratinocytes in 8-MOP and PUVA groups decreased significantly more than in the control and LVA groups at 72nd hour after culture (p<0.01). 2) The number of melnocytes showed no differences between the groups at 72nd hour after culture (p>0.05). 3. Melanin contents in iultured human melanocytes The melanin contents increased significantly in the PUVA groups compared to that in the other groups at 72nd hour after culture (p<0.01). CONCLUSION: In culturel human keratinocytes, PUVA has no effect on the morphology and differentiation, hut inhibit proliferation. In cultured human melanocytes, PUVA has no effect on morphology and proliferation, but it increases the melanin contents.
