In electrification of the Honam line, the grounding method of the copper wire shield of 66㎸ feeder cable was disputed. This paper describes that the review of the proper earthing method(one-side earthing or both-side earthing) under consideration of the site condition and the acceptability of the induction voltage of the shield on the end of the cable.

N/A Background : Seborrheic dermatits and atopic dermatitis are clinically different diseases, but symptoms and signs of atopic dermatitis often can be found simultaneously in patients with seborrheic dermatitis. Objective : The aim of this study was to investigate if patients with seborrheic dermatitis have the symptoms and sign of atopic dermatitis at the same time, and to measure the levels of serum IgE and eosinophil counts. Methods : Sevently eight patients with seborrheic dermatitis on the scalp and face, 64 patients with atopic dermatitis and 88 normal subjects were observed clinically by the dermatologist and studide statistically using questionnaires. Levels of total IgE and eosinophil counts were measured by blood sampling in the total number of subjects. Results : Among 20 items of the questionnaire regarding the symptoms and signs of atopic dermatitis, 6 items were more frequent in only the atopic patients than in the normal control, 2 items were more frequent in only the seborrheic dermatitis patients and 8 in both diseases. The mean levels of serum IgE in seborrheic dermatitis patients were lower than in atopic patients, but significantly higher than that of the normal control and 21.3% of those had IgE levels above the normal range. When we classified the seborrheic dermatitis patients according to the combined skin diseases, the mean levels of IgE were highest in the patients with dermatitis and male pattern bladness, but the value was not significant compared to that of the normal control. The mean levels of eosinophil counts in seborrheic dermatitis patients were higher than in the normal control, but it was not significant statistically. Conclusion : According to the results of the study, the patients with seborrheic dermatitis showed a higher incidence of symptoms and signs of atopic dermatitis and higher levels of serum IgE than the normal subjects. Further studies will be needed to elucidate the relationship between seborrheic dermatitis and atopic dermatitis. (Korea J Dermatol 1999;37(9) : 1269∼1275)

황(sulfur, S)은 모든 식물의 필수 영양원소이며 식물에서 황산염의 형태로 유입되어 체내에서는 황화수소(H2S)로 환원되어 황 함유 아미노산(cysteine, methionine)의 합성에 이용된다. 글루코시놀 레이트(glucosinolate, GSL)는 황과 질소를 함유하며 로켓샐러드, 케일, 브로콜리, 배추, 양배추와 같은 배추과 채소에 함유되어있는 2차 대사산물로, 항암 효과가 있다. 싹이 트는 과정동안 황을 공 급해 주면, 새싹에 있는 GSL 합성이 증가할 수 있고, 식물체 내에서 황 함량이 높을수록 GSL 축적이 많이 되지만 황이 결핍되면 생합성이 활성화 되지 못하여 GSL 함량이 감소한다고 보고되었다. 따라서 본 실험은 배추과 채소(로켓샐러드, 코마츠나, 콜라비, 케일)의 생장 시 시비되는 양액 중 황 성분의 농도에 의해 GSL 함량에 미치는 영향을 조사하였다. 배추과 채소의 재배기간은 2016년 3월 8일부터 2016년 5월 10일까지 총 63일이었으며 이 중 양액 처리기간은 36일이었다. 대조구(S 1.0)와 실험구(S 0.1, 0.5, 2.0, 3.0 mM)로 구분하여 양액 재배하였다. 배추과 채소 내 GSLs는 HPLC로 분리 및 동정 후, 외부 표준물질 sinigrin의 peak area와 각 성분의 response factor를 이용하여 정량하였다. 로켓샐러드와 코마츠나, 콜라비에서 GSL 함량은 S 3.0 mM(21.71; 57.47; 8.95)에서 가장 높았으며, S 0.1 mM(2.41; 2.01; 0.96 μmol·g-1 dry wt.)에서 가장 낮았고, 황 양액 농도가 증가함에 따라 총 GSL 함량이 높아졌다. 그렇지만 케일의 경우 S 2.0 mM에서 가장 높고 (19.19), S 2.0까지는 황 농도가 높아질수록 GSL 함량이 증가하였지만, S 3.0 mM에서는 GSL 함량 (14.80 μmol·g-1 dry wt.)이 감소하였다.

Background:Pain in the form of acute neuritis and postherpetic neuralgia is by far the most frequent and most debilitating complication of herpes zoster. The pain of acute herpes zoster may be severe, but it is usually transitory. Some patients, with the elderly at particular risk, go on to develop postherpetic neuralgia. Postherpetic neuralgia is often severe and, unfortunately, refractory to most forms of treatment. Objective:The purpose of this study was to compare the severity of acute pain and incidence of postherpetic neuralgia by age group, dermatomal distribution and the presence and absence of associated diseases. Methods:We observed the severity of initial pain, changes in severity of pain during treatment, and the incidence of postherpetic neuralgia in 105 patients with herpes zoster with the same therapeutic measures (systemic steroid, acyclovir, analgesics, and tricyclic antidepressant). And we compared them by age group (the young & middle age vs the old age group), dermatomal distribution(trigeminal, cervical, thoracic, and lumbosacral), and the the presence and absence of associated diseases respectively. And we also analyzed the relationship between the incidence of postherpetic neuralgia and the severity of initial pain. Results: 1. Sixty-six patients (63%) of the total number of subjects complained of initial `severe pain', and the incidence of initial `severe pain' was significantly higher in the old age group (78%) compared with the young & middle age group (48%). But, there was no significant difference by dermatomal distribution and the presence and absence of associated diseases. 2. The duration of pain was 2-4 weeks in 27 patients (26%), 1-2weeks in 26 (25%), more than 8 weeks(postherpetic neuralgia) in 24 (23%). 3. The mean comparative value of the severity of pain was 38% of initial pain after 3 days of treatment, 22% 1 week, 15% 2 weeks, 8% 4 weeks, and 5% 8 weeks, respectively. But, there was no significant difference in changes of severity of pain by age group, dermatomal distribution, and the presence and absence of associated diseases. 4. The incidence of postherpetic neuralgia was significantly higher in the old age group (35%) compared with the young & middle age group (11%). But there was no significant difference by dermatomal distribution and presence and absence of associated disease. And the incidence of postherpetic neuralgia was also significantly higher in the initial 'severe' pain group (33.3%) than in the initial 'mild' pain group (14.3%) and the `moderate' pain group (3.1%). Conclusions:Older patients with herpes zoster showed severer initial pain and a higher incidence of postherpetic neuralgia. But there was no significant difference in the severity of initial pain and incidence of postherpetic neuralgia by dermatomal distribution and the presence and absence of associated diseases. And patients with initial severe pain showed a higher incidence of postherpetic neuralgia than those with mild and moderate pain, respectively.

Although a number of remedies like corticosteroids, retinoids, griseofulvin, PUVA, cyclosporine, antibiotics, dapsone, cyclophosphamide, surgery, methotrexate, radiation therapy, antimalarial drugs, psychotharapy and psychiatric medications have been used to treat lichen planus, there were no specific methods until now. We report herein an interesting case of lichen planus in which complete healing was achieved by griseofulvin administration. The patient was a 54-year-old male who for 3 months had variouly sized and shaped, flat-topped, scaly, violaceous papules and plaques on the whole of his body. We confirmed the patients disease as lichen planus by a histopathologic examination of a skin biopsy specimen and gave him 500mg ultramicronized griseofulvin daily in divided dosages. After 12 weeks of the medication nearly all of the skin lesions were regressed, and by 14 weeks all skin lesions had disappeared leaving hyperpigmentation. Up to now, l9 months after discontinuation of the medication, no recurrence of the disease has been noted.
