PURPOSE: This study aimed to compare differences on sexual satisfaction between non-smokers and smokers of Korean adult males. METHOD: The subjects of this study were 304 current smokers and 331 current non-smokers(stop smokers, never smokers) (58.0%). Because of the nature of the study, the participants were recruited through a home page advertisement of a brand newspaper company in Korea, and the survey was done through Internet system. The tool to measure participant's sexual satisfaction was adopted from the Arizona Sexual Experience Scale-Male. RESULT: Participant's age ranged from 20 to 49, mostly in their 30s-40s(96.1%). They were smoking average of 15 cigarettes per day. There were no significant difference on sexual satisfaction between current smokers and non- smokers(t=-.55, p>.05). However, there were significant difference on sexual satisfaction between ever smokers(n=481) and never smokers(n=154) (t=2.10, p<.05). There were significant differences an erectile and orgasm satisfaction according to number of cigarettes they smoked per day. 54.5% smokers who said that they have difficulty in keeping erectile state considered on smoking cessation within 30 days whereas 24.2% in those who said that keeping erectile state was easy. CONCLUSION: Informing about the high risk of sexual dysfunction with cigarette smoking should become a important part of smoking cessation education and for smoking adolescents.

PURPOSE: To characterize strain-specific differences in radiation response in murine tissues with different radiosensitivity. MATERIALS AND METHODS: Six-week old male mice of 2 strains, C57Bl/6J and C3H/HeJ, were given whole body gamma-radiation with a single dose of 10 or 25 Gy. At different times after irradiation, mice were killed and tissues with different radiosensitivity, thymus and liver, were collected. Each tissue sample was stained with hematoxylin and eosin and apoptotic cells were scored. Expression of p53, Bcl-2, Bcl-x, and Bax was analysed by western blotting and densitometry. RESULTS: Radiation induced massive apoptosis in thymus with a peak level at 8 h after radiation. With 10 Gy irradiation, apoptotic indices in C57Bl/6J and C3H/HeJ were 81.0 2.5% and 59.4 4.0%, respectively (p<0.05). Radiation upregulated the expression of p53, Bcl-x, and Bax, but not Bcl-2; p53 with a peak level of 2.5 fold (C57Bl/6J) and 1.4 fold (C3H/HeJ) at 4 h, Bax with a peak level of 2.6 fold (C57Bl/6J) and 1.3 fold (C3H/HeJ) at 8 h, and Bcl-x with a peak level of 11.1 fold (C57Bl/6J) and 8.2 fold (C3H/HeJ) at 8 h after radiation. In liver, however, radiation-induced apoptosis was minimal (peak apoptotic index of 2.1% in C57Bl/6J and 1.7% in C3H/HeJ). None of p53, Bcl-2, Bcl-x, and Bax was significantly increased. CONCLUSIONS: Induction of apoptosis and regulation of related genes by radiation were tissue specific. Strain difference of radiation-induced apoptosis was well coupled with theinduction of related genes in thymus, a radiosensitive tissue. This study shows that quantitative difference of radiation induced apoptosis by strain is regulated at the gene level with the involvement of multiple genes.

PURPOSE: The purpose of this study was to identify the uses of complementary and alternative therapies(CAT), pain, and quality of life(QOL) in patients with chronic back pain. METHOD: A descriptive survey was conducted using convenient sample. One hundred sixty two patients with chronic back pain participated in this study. Types and satisfaction of CAT, pattern of back pain, and QOL were investigated. RESULT: 83.3% of all participants reported in the use of CAT. The most common types of CAT used were acupuncture and half-bath. Yoga were the most high satisfaction among the types. The mean score of back pain was 4.12, QOL was 3.10, that was mostly low score. There was no significant difference back pain and QOL between CAT user and nonuser. Correlation with satisfaction of CAT according the most using types were a negative correlation with back pain and a positive correlation with QOL. CONCLUSION: These result indicate that the mostly patients with back pain feels the satisfaction of CAT use. It is important that provide the obvious information about CAT which can be helpful to patient.

It is difficult to distinguish benign from malignant, pulmonary nodule by conventional roentgenologic examination. But CT makes it easier to evaluate adjacent parencymal invasion, pleural or mediastinal extenstion,or early metastasis to intra- or extrathoracic lymph node as well as distant organs, although only a solitaryperipheral pulmonary nodule is seen on plain radiograph. Authors reviewed CT of 22 cases of histopathologically confirmed primary lung cancer seen as a solitary peripheral pulmonary mass from May 1980 to Sep. 1984 at DongsanMedical Center, Keimyung University. The results are as follows: 1.The incidence was most common in the 6thdecade(36%). Male to female ratio was 10:1 and 2 females all had bronchioloalveolar cell carcinoma. 2. Thedistributions of histologic cell type were as follows: squamous cell carcinoma 40%, adenocarcinoma, small cellcarcinoma, bronchioloalveolar cell carcinoma and unclassified carcinoma 14% in each cases, and adenoid cysticcarcinoma 4% . 3. The CT findings were as follows: a) Superior and posterior basal segments of both lower lobeswere most frequently involved(68%). b) The mean diameter of the mass was 48mm, and most common in the range of30-49 mm in the greatest dimension(46%). c) The mean CT atttenuation value was 57 H.U., and most common in thegroup of 41-70 H.U. (64%). d) Lymph node metastasis was found in 13 (59%) of 22 cases, and the involved nodes wereas follows: hilar nodes 10 cases, paratracheal nodes 8 cases, subcarinal nodes 7 cases and extrathoracic nodes 3cases. In 2 of 3 cases with small cell carcinoma, diffuse multiple lymph nodes were involved. e) Distantmetastasis was seen relatively early in 3 cases; cerebral metastasis in 1 case of squamous cell carcinoma, rightaderenal metastasis without intrathoracic lymph node metastasis or invasion of adjacent structures in 1 case ofbronchioloalveolar cell carcinoma, and liver and bone metastases in 1 case of unclassified carcinoma. f) Adjacentpleural or mediastinal invasion was found in 7 cases(32%): pleural invasion along chest wall in 4 cases, andinvasion of adjacent mediastinal pleura in 3 cases of 2 squamous cell carcinoma and 1 unclassifed carcinoma. g)Calcifications witihin the mass were found in 5 cases (23%), and most common in squamous cell carcinoma(3 cases).In all cases, a few granular calcification were seen along the peripheral margin of the mass. h) Tumor necrosiswas seen in 4 cases(18%), and 3 cases were squamous cell carcinoma, and one of them showed irregular centralcavitation. i) The margins of tumor were irregularly lobulated with radiating spiculations in all except one ofadenoid cystic carcinoma, which revealed oval shaped, smooth clear margin. j) In 9(41%) of 22 cases, someenlargement of pulmonary vessels with perivascular linear infiltrations were found in the adjacent lungparenchymes of the mass, which were thought to be retrograde perivascular lymphangitic spread along pulmonaryvessels.

Phospholipase C (PLC) plays a pivotal role in transmembrane signal transduction pathway for cellular proliferation differentiation and growth. Thus far, there have been few reports in which PLC activity was investigated in human malignant neoplastic tissues. In the present study, we evaluated PLC activity in 23 human gastric cancer tissues and normal mucosal tissues to investigate whether alteration of PLC activity is associated with gastric cancer. The amount of [14C] diacylglycerol, one of the earliest products of inositol phospholipid hydrolysis by PLC, was measured by thin layer chromatography. Also, expression of PLC-gamma1, which is one of the most important PLC isozymes,was examined by immunohistochemistry using specific monoclonal antibody directed against PLC-gamma1. The results are summarized as follows. PLC activity in all 23 gastric cancer tissues (1.35+/-1.04 units/mg of protein) was significantly higher than normal mucosal tissues (0.28+/-0.21 units/mg of protein) (P<0.001). PLC activity in gastric cancer tissues was not correlated with histologic grade (P>0.05). PLC-gamma1 immunoreactivity was detected in all of 23 cases studied. The intensity and extent of PLC-gamma1 immunoreactivity was not correlated with PLC enzyme activity, although stronger intensity was demonstrated in malignant cells in comparison to normal gland epithelial cells. The present study provides the first evidence of significant elevation of PLC activity in human stomach cancer tissues. Our results strongly suggest that PLC might be involved in tumorigenesis and/or progression(uncontrolled continuous cycling of cells) of human gastric cancer. Further studies are needed to elucidate the role of elevated PLC activity in cancer tissues.

The effects of Norepinephrine(NE), Isoproterenol(ISO) and Nitroglycerin(NTG) on the hemodynamic, arterial and venous blood gas analysis changes in air embolized cats were investigated. Under general anesthesia with Halothane, cats were injected 1ml/kg of air acutely to decrease mean arterial pressure(MAP) about 30 to 40 percent of control value through superior vena cava. 14 cats were divided into two groups of 7 each (group 1 and 2). Group 1 cats received NE and then NE with NTG therapies. In group 2, ISO and then ISO with NTG therapies were taken. The results were as follows: 1) Hemodynamic changes. Group 1: NE increased the MAP from 69+/-8 mmHg(mean+/-SD) to 116+/-14mmHg(p<0.05), decreased the right atrial pressure(RAP) from 18+/-4mmHg to 11+/-3mmHg(p<0.05). Combined therapy with NTG decreased the MAP from 116+/-14 mmHg to 101+/-10 mmHg(p<0.05), the HR from 167+/-16 beats/min(bpm) to 150+/-4 bpm(p<0.05), the RAP from 11+/-3 mmHg to 8+/-3mmHg(p<0.05). Group 2: ISO increased the MAP from 81+/-8mmHg to 112+/-14 mmHg(p<0.05), and the HR from 152+/-21 bpm to 190+/-24 bpm(p<0.05). Combined therpy with NTG decreased the HR from 190+/-24 bpm to 174+/-19 bpm(p<0.05), the CVP from 14+/-7mmHg to 14+/-3mmHg(p<0.05), and the RAP from 13+/-3mmHg to 12+/-3mmHg(p<0.05). 2) Blood gas analysis changes. Group 1: NE with NTG combined therapy increased the arterial oxygen tension from 335+/-54 mmHg to 372+/-49mmHg, decreased the venous CO2 tension from 52+/-9mmHg to 47+/-4mmHg. Group 2: ISO with NTG combined therapy increased the arterial oxygen tension from 344+/-85mmHg to 375+/-50mmHgIp<0.05). (paired t-test, p<0.05). In conclusion, NE and ISO increased MAP in venous air embolism with moderately decreased MAP. Inotropic agent with NTG therapy improved arterial oxygenation.
