Eruptive vellus hair cysts and steatocystoma multiplex have clinical similarities in terms of age of onset, location and appeararice of the lesions, but histopathologic feitures are distinctively differen-tiated. We present herein a 37-year-old woman with eruptive vellus hair cyst and steatocystoma multiplex as well. The histopathologic sections from 2 different lesions showed features of both eruptive vellus hair cyst with sebaceous gland in and near the cyst wall, and steatocy toma multiplex with rudimentary hair follicle near the cyst wall. This case may support the premie that eruptive vellus hair cyst and steatocystoma multiplex have a common developmental origin.

Acetylcholine is one of the major neurotransmitters in visual system of rats. Cholinergic, serotonergic and gamma-aminobutyric acid(GABA) ergic projections are known as modulators of visual processing. The purpose of this study was to examine the effects of unilateral orbital enucleation on the amount of acetylcholine and its receptor bindings in dorsolateral geniculate body, superior colliculus and visual cortex of rats, and on motor activites. The amount of acetylcholine was measured by gas chromatography; whereas [3H]quinuclidinyl benzilate(QNB) bindings to muscarinic receptors were examined by autoradiography. Motor activity was measured by activity meter for 24 hours. The results of this study were as follows: 1. The amount of acetylcholine in superior colliculus significantly increased at 1 week after enucleation, but it decreased at 2 and 4 weeks after enucleation. In visual cortex, the amount of acetylcholine did not change at 1 week after enucleation, but it significantly decreased at 2 and 4 weeks after enucleation. 2. After enucleation, [3H]-QNB binding to muscarinic receptors gradually decreased over the 4 weeks in dorsolateral geniculate body, superior colliculus and visual cortex. 3. Locomotor activity of rats did not show any change at 1 week after enucleat ion, but it decreased at 2 and 4 weeks after enucleation. In conclusion, unilateral orbital enucleation resulted in a reduction in the amount of acetylcholine and muscarinic receptors in rat visual system, which was speculated to be a major cause of a decrease in physical activity.

Eccrine spiradenoma is a txnign, painful tumor of the skin, which probably originates in the coil of the eccrine sweat glands and presents a characteristic clinical and pa.hological picture. However recently, the weakness and inconsistency of the enzymes histochemican, actions and electron microscopic findings, and the presence of numerous undifferentiated and indetirn, inate cells suggest a rather low degree of differentiation. We present herein four cases of eccrine spiradenoma which show livrse histopat.hologic characteristics including typical rosette-like structure, ductal structure, vacuar structure and mixed type, respectively. This report may support the premise that eccrine spiridinoma is defived not only from the eccrine duct but also from pluripotential stem cells.

Lichen nitidus, characterized by its typical clinical and histopathologic findings, is an uncomrnon chronic dermatosis of unknowned etiology. The distribution of this disease is most often localized, but in some cases it may becorne generalized. Some authors suggested that lichen nitidus is a variant of lichen planus in terms of its coincidence, ultrastructural and immunophenot,ypic studies. We report herein a case of lichen nitidus which presents dark brown linear, grouped, or confluent papules on the face, cheat, and upper extremities, accompanying with the histopathologic findings of pigmentary incontirence in the portion of claw clutching a ball appearance. This report suggests that lichen nitidus shows hyperpigmentation clinically and could be one of the dermatoses which exhibit pigmentavy incontinence in a histopathologic study.

8.The Impact of Alcohol and Caffeine Intake on Body Mass Index, Alcohol Use Disorder, and Quality of Sleep among University Freshmen.
Journal of Korean Biological Nursing Science 2015;17(4):363-371
PURPOSE: The purpose of this study was to assess alcohol and caffeine intake and identify the impact of alcohol and caffeine intake on body mass index, alcohol use disorder, and quality of sleep among university students. METHODS: This study design was accomplished with a cross sectional survey and conducted from May to June 2014. One hundred and twenty-four freshmen of E university in S city, Korea were selected and evaluated by self-administered questionnaires. Alcohol and caffeine intake were measured by self-reported recall. The data were analyzed using descriptive analysis, independent t-test, one-way ANOVA, Pearson's correlation, and multiple linear regression. RESULTS: The average amount of alcohol intake was 175.02 +/- 219.97 g and the proportion of freshmen who took in more than 40g per day of alcohol was 75%. The average amount of caffeine intake was 116.79 +/- 111.14 mg. Factors influencing alcohol use disorder were dwelling type (t=2.25, p=.027) and alcohol intake (t=8.11, p<.001). And, the factor influencing quality of sleep was caffeine intake (t=3.88, p<.001). CONCLUSION: In order to reduce the harmful drinking of university students, preventive activities for freshmen are required and efforts on the part of the school needed.

PURPOSE: We conducted a phase II study in previously untreated patients with unresectable stage IIIB or IV non-small cell lung cancer to evaluate the response rate and toxicity of the combination chemotherapy regimen of etoposide, ifosfamide and cisplatin. MATERIALS AND METHODS: From September 1993 to December 1996, twenty patients with advanced non-small cell lung cancer (stage IIIB 5 and IV 15) (squamous cell 8, adeno- carcinoma 12), were enrolled in this study. There were 13 (65%) males and 7 (35%) females, and median age of patients were 56 years (range: 34~66). Eighteen patients had performance status (ECOG) 0~1, two patients had performance status 2. Treatment was consisted of cisplatin (20 mg/m2 i.v., day 1~4), VP-16 (etoposide) (75 mg/m2 i.v., day 1~4), ifosfamide (1000 mg/m2 i.v., day 1~4) with mesna. This treatment was repeated every four weeks. RESULTS: The overall response rate was 25%. Complete response rate was 5% (1/20) and partial response rate was 20% (4/20). The median cycle of response was 4 (2~6) cycles. The median overall survival time was 28 weeks (9~98 weeks). The median time to progression was 10 weeks (3~50 weeks). Toxicities were evaluated by WHO criteria. Toxicity > GradeIII included: leukopenia 1.6%, thrombocytopenia 3.2%, nausea and vomiting 15%, alopecia 30%, stomatitis 10%. These toxicities were tolerable and reversible. CONCLUSION: VIP regimen was not superior to previous regimens for advanced non-small all lung cancer, and the toxicities were tolerable.

CD44 is a hyaluronic acid receptor that exists as a standard 90-kd form (CD44H) as well as several CD44 variants isoforms are produced through alternative splicing. Alternatively spliced variants of the CD44 molecule have been found to be associated with invasive and metastatic potential of cancer cells and poor prognosis in several types of carcinoma. The purpose of the present study is to define the expression of CD44H and CD44v6 in ovarian tumors and to investigate whether the expression of these molecules is associated with adverse prognosis. We evaluated the expression of CD44 isoforms in 58 ovarian tumors by means of immunohistochemistry, and correlated between CD44 expression and the histologic types, tumor grade, peritoneal implants, pseudomyxoma peritonei and FIGO stage. While the CD44H was commonly expressed in ovarian tumors, the CD44v6 was expressed in a minor proportion of serous tumors in comparison with frequent expression of v6 isoform in mucinous tumors. The CD44H expression was significantly higher in stage I/II than in stage III. However, there was no correlation between the expression of CD44 and the presence of peritoneal implants or pseudomyxoma peritonei. These results suggest that CD44H could play an important role in the adhesive function in the lower stage of the ovarian tumor and reduced expression in the higher stage might be related to the metastasis and widespread invasion of ovarian carcinoma cells.
