Nitric oxide (NO) induces apoptotic cell death in murine RAW 264.7 macrophages. To elucidate the roles of SEK1/MKK4, a upstream kinase for both c-Jun N-terminal kinase/stress-activated protein kinase (JNK/SAPK) and p38 kinase, on NO-induced apoptosis, we generated clones of RAW 264.7 cells which stably overexpressd kinase inactive SEK1 (RAW/SEK1-Kl) or wild type SEK1 (RAW/SEK1-WT). Treatment of kinase inactive SEK1 transfected RAW 264.7 cells (RAW/SEK1-Kl) with sodium nitroprusside (SNP), a NO generating agent, significantly decreased the cell viability up to 20% of RAW control cells which were treated with the same amount of SNP. However, RAW/SEK1-WT cells were less susceptible to NO induced apoptosis. For a while, caspase-3 like activity in NO treated RAW/SEK1-Kl cells was significantly increased with parallell to apoptotic death rate. However, caspase1 like activity was not affected by NO in any transfectants. The NO induced apoptosis in RAW/SEK1-Kl cells was significantly prevented by the addition of caspase-3 like inhibitor (N-Ac- DEVD-CHO). In addition, the phosphotransferase activity of JNK1 in NO-treated RAW/SEK1-WT is significantly increased, but not in RAW/SEK1-Kl cells. These results suggest that SEK1 may play anti-apoptotic role in RAW cells from NO-induced apoptosis.

A 6-year-old male patient had been suffering from angular cheilitis and paronychia with fragmentation and dystrophic change of the finger nails. Laboratory findings showed low serum iron level and anemia. Immunologic studies revealed defects in cell mediated immunity. KOH examination and culture of specimens from the lesions showed hyphal elements and growth of Candida albicans respectively. Concomitantly itraconazole and iron sulfate were administered. Four months after treatment he was free of any clinical evidence of the disease.

Trichotillomania is the cllinical syndrome of alopecia resulting from the repetative pulling, plueking and breaking of ones own hair. We report four cases of trichotillomania in 10 year old children. The lesions were limited to the scalp. All of them had psychiatric problems in the school or home according to a psychiatric consultation. The histopathologic examinatiorii revealed a normal number of hair follices, empty hair follicles and no inflammatory reaction. The treatment led to hair growth in three cases but one case did not respond to the treatment.

Clear cell sarcoma of tendon and aponeurosis is a rare malignant tumor. It occurs chiefly in young adults, predominates in women and is most common in the regions of the foot and ankle. We report a case of clear cell sarcoma of tendon and aponeurosis in s 22-year-old man. he pstient had had a asymptomatic, normal skin colored, relativerly hard, dome shsped nodule on the anterior chest for 6 months. Histopsthologic findings revealed uniform pattern composed of compact nests of round or fusiform cells which had clear cytoplasm and were surrounded by delicate framework of fibrocollagenous tissue, and the individual tumor cell had a fairly regular appearance of possessing round to avoid vesicular nucleus with prominent basophilic nucleolus. One year after surgical excision and post operative radiotherapy, there was no recurrence.

The authors studied depression in 5,869 college students (male: 3,893, female: 1,976) using Zung's Self-Rating Depression Scale (SDS). The results are as follows: 1) Female college students showed significantly higher total depression scores than male college students (p<0.001). 2) The items of confusion, indecisiveness, and psychomotor retardation were scored higher in both groups and the items of suicidal rumination, psychomotor agitation, constipation and tachycardia were scored lower in both groups. 3) 18.2% of male college students showed rather serious depression level of score 50 or higher, while 33.1% of female college students showed the same scores. 4) The psychosocial factors relating to pessimistic views to past, present & future self-images showed significantly high depression scores. 5) The depression items of fatigue, anxiousness, tachycardia, apprehension, fear, and body aches & pain were correlated significantly over 0.40 of correlation coefficient.

The authors studied anxiety, using Zung's SelfRating Anxiety Scale (SAS), in the subjects of 3,893 male and 1,976 female college students of Yeungnam University. The authors collected the reports of SAS during the periods from October to November, 1984, and applied ANOVA and ttest on the anxiety scores in order to compare them between various psychosocial factors, and sexes. The results could be summarized as follows: There was significant difference in the mean averages of total anxiety scores between male and female students; male students scored 36.92±7.07, female students scored 39.63±7.51, p<0.001. The anxiety scores relating to the items of sweating, apprehension, restlessness, insomnia, dyspnea were relatively higher in both groups. The anxiety scores in the items of paresthesias, mental disintegration, tremors, faintness, dizziness were lower in both groups. Two hundred and one male students (5.2%) showed seriously high anxiety scores of 50 or higher, while 201 female students (10.2%) showed the same scores. So the authors inferred that the features of anxiety symptoms were much the same in our country, but females showed more various symptoms and higher level of anxiety than males. In a comparison between male students in different school grades, freshmen showed the highest level of anxiety scores and as the grades of the students became higher, the levels of anxiety scores were lower. The female students who resided in dormitory or other residences, and whose educational fees were paid by brothers or sisters, showed higher level of anxiety scores. There was s strong tendency toward higher anxiety scores in the students who were dissatisfied with their colleges or departments, and who had pessimistic views of self-image in the past, present, or future, in both groups.
