Background : Although patients with stage IV non-small cell lung cancer are known to have a poor prognosis, the prognostic factors for survival have not been well evaluated. Such factors may be different from those for overall survival. This study was performed to analyze the prognostic factors for survuval and the variation of survival according to metastatic organ, in patients with stage IV non-small cell lung cancer. Materials and Methods : From January 1997 to December 2000, 151 patients with confirmed stage IV non-small cell lung cancer were enrolled into this study retrospectively. The clinical and laboratory data were analyzed using univareate Kaplan-Meied and Multivariate Cox regression models. Results : On univariate analysis, age, performance status, serum albumin level, weight loss, forced expiratory volume in one second (FEV1), systemic chemotherapy, the number of metastatic organs and serum lactate dehydrogenase (LDH) level were significant factors (p<0.05). In multivariate analysis, important factors for survival were ECOG performance (relative risk of death [RR]: 2.709), systemic chemotherapy (RR: 1.944), serum LDH level (RR: 1.819) and FEV1 (RR: 1.774) (p<0.05), Metastasis to the brain and liver was also a significant factor on univariate analysis). The presence of single lung metastasis was associated with better survival than that of other metastatic organs (p=0.000). Conclusion : We confirmed that performance status and systemic chemotherapy were independent prognostic factors, as has been recognized. The survival of stage IV non-small cell lung cancer patients was different according to the metastatic organs. Among the metastatic sites, only patients with metastasis to the lung showed bettrer survival than that of other sites, while metastasis of the brain or liver was associated with worse survival than that of other sites.

Objectives : In the present study, anti-metastatic properties of the methanol extract of L. obtusiloba (MLO) were evaluated. Methods : To determine the effect of MLO on cancer metastasis, we checked matrix metalloproteinase-2 (MMP-2) and matrix metalloproteinase-9 (MMP-9) activities and expressions in B16F10 melanoma cells. In addition, we performed cell migration assay as well as invasion assay using Matrigel. Finally, we used an in vivo lung metastasis model to confirm the anti-metastatic activity of MLO. Results : 1. MLO showed potent inhibitory effects on MMP-2 and MMP-9 activities and expressions via down-regulation of activation of NF-${\kappa}B$ in B16F10 melanoma cells. 2. Melanoma cell migration and invasion were down-regulated by MLO treatment. 3. Not only in vitro model, but MLO also significantly suppressed lung metastasis in vivo. Conclusions : The present results indicate that MLO has strong inhibitory effect on cancer metastasis. Therefore, L. obtusiloba could be a valuable anti-metastatic agent.

Nickel oxide was recovered through roasting of a spent catalyst for hydrogenation reaction. Nickel on Kieselguhr catalysts were prepared by a precipitation method after a treatment of the recovered-nickel oxide with an acid. Effects of roasting temperature of the spent catalyst on recovery of nickel oxide was investigated. Most of nickel oxide could be recovered through roasting of the spent catalyst at $1000^{\circ}C$. In regeneration of catalysts by the precipitation method after the treatment of nickel oxide with an acid, the effect of promoter, precipitation condition and reduction condition on catalytic performance in vegetable oil hydrogenation were investigated. The addition of CaO or $Ce_2$$O_3$ resulted in an increase of catalytic activity.

A case of inflammatory pseudotumor of the entire lung In a 61-ycar-old man is prcscntcd. The respiratory symptoms developed 2 months ago and progressed rapidly and the diagnosis of chronic pneumonia with ateletectasis of the entire lung, destroyed lung by tuberculosis and sepsis hAd to be ruled out The operative finding was different from our expectation. This case suggests that the Inflammatory pseudotumor can manifest as a whole lung-involving ass. Inflammatory pseudotumor is a nonneoplastic reactive pulmonary mass lesion that resembles tumor but shows little or no growth. Thc inflammatory pseudotufor usually present as a solitary round lung mass but in this casts progressed rapidly and destroyed the whole lung, which is rare. The patient was discharged with no problem and with outpatient followup.

Magnetic separation was carried out in order to improve the magnetite grade of the spent iron oxide catalyst, that was composed with magnetite, ceria and soluble alkaline salt. The recovery of magnetite from the spent iron oxide catalyst was over 99%, and the magnetite contents was upgraded to about 80% from 70% via wet type magnetic separation at 500 Gauss. This improvement was due to the removal of alkaline salt by water instead of the magnetic separation.

Background: Pulmonary sclerosing hemangioma is rare, but still the second most common benign lung tumor, occurring most1y in middle-aged women. Methods: From January 1985 through April 1993, we experienced eight cases of solitary pulmonary sclerosing hemangioma. Results: Subjects studied were 7 female and 1 male patients. They ranged from 14 to 63 years of age(mean age, 43.8 years) at the time of operation. The patients were frequently asymptomatic and the tumor was often shown to be a large lobulated mass on radiographic examination. The tumor can usually be diagnosed on operation because of its subtle clinical and radiographic presentation. All eight cases were diagnosed intraoperatively. The mean interval between initial radiographic detection and operation was 7.9 months. Out of 8 cases, preoperative impression of benign tumor was made in 4 cases, whereas malignant tumor was suspected in the remaining 4 cases. Enucleation, wedge resection or lobectomy was performed which appropriate in each patient. Conclusion: Surgical removal of the tumor preserving as much lung parenchyma as possible is indicated for proper diagnosis and treatment of this condition.

Pulmonary blastoma are a family of tumors in which the glands or mesenchyme composing the neoplasm are primitive or emb yonal in appearance. We report a pulmonary blastoma occurring in a 31 years old man. An abnormal shadow was detected in the right lower lung field in a routine chest X-ray film. The preoperative imaging films showed about a 5cm sized well circumscribed solid tumor of the right lung. A preoperative clinical diagnosis of primary lung cancer was considerd. The operative field showed that the hard, round mass, 6$\times$5$\times$4cm in diameter was localized in middle lobe of the right lung, and partially adhered to the upper lobe, pericardium and diaphragm. Right middle lobe lobectomy, right upper lobe wedge resection, partial pericardiectomy and diaphragm resection with plication was performed with radical Iymph node dissection. Histopathologic diagnosis was pulmonary blastoma (Biphasic blastoma). It is considered that the prognosis of biphasic blastoma is worse than WDFA(well differentiated fetal adenocarcinoma). There are no other available treatments except for surgical resection. It is suggeste that it is necessary to collect as many cases as possible, to make definite classifications and to examine the clinical course and prognosis of pulmonary blastoma.

A basic study on the recovery of heavy metals such as Zn, Ni, Cu and Fe ions from wastewater was carried out with the spent iron oxide catalyst, which was used in the Styrene Monomer(SM) production company. The heavy metals could be recovered more than 98％ with the spent iron oxide catalyst. The alkaline components of the spent catalyst could be precipitated the metal ions of the wastewater as metal hydroxides at the higher pH 10.6 in Ni, pH 8.0 in Cu, pH 6.5 in Fe, pH 8.5 in Zn. But the metal ions are adsorbed physically on the surface of the spent catalyst in the range of the pH of the metal hydroxides and pH 3.0, which is the isoelectric point of the iron oxide catalyst.

Immunoglobulin G4 (IgG4)-related lung disease can have various clinical courses. To our knowledge, reports of IgG4-related lung disease with waxing and waning pulmonary infiltrates only are very rare. A few lung nodules and ground glass opacities were incidentally found in a pre-operative evaluation in a 36-year-old female. The lung lesions showed waxing and waning in the follow-up chest CT. She underwent a surgical biopsy, and IgG4-related lung disease was confirmed.
