Objectives : To evaluate the long-term survival effects of traditional Korean medicine (TKM) on refractory metastatic lung cancer and small cell lung cancer (SCLC), which have historically poor survival rates. Methods : A retrospective study was conducted using the medical records of two patients in Daejeon University hospital. The first patient, with SCLC, was treated from January 2000 to December 2009 and the other, with metastatic pulmonary cancer from primary hepatocellular carcinoma (HCC), was treated from September 2004 to February 2014. The patients were treated with herbal medicines at one-month intervals. During hospitalization, acupuncture and indirect moxibustion were performed concurrent with the administration of Western therapy. Treatment efficacy was assessed monthly using chest radiography, chest computed tomography, and laboratory examination data, and by measuring patient performance status. Results : Both patients exhibited a stable disease course for more than 9 years after the initial diagnosis of intractable lung cancer, suggesting that their disease status was controlled by TKM. Conclusions : We suggest that a combination of TKM with conventional Western therapy for refractory lung cancer patients is effective in controlling various symptoms related to lung cancer and improving quality of life, and may potentially prolong overall survival.

We analyzed the effects of temperature on the survival, development, and reproduction of the non-diapause Asian corn borer, Ostrinia furnacalis (Lepidoptera: Crambidae). A 16:8 h light:dark photoperiod was supplied to the non-diapause stages of O. furnacalis. The insects were raised on an artificial diet at seven constant temperatures between 15 and 35℃ for immature stages, and eight temperatures between 13 and 33℃ for the adult stage. The survival rate of eggs exceeded 70% at all temperatures, whereas survival of larvae was as low as 7.4% at 15℃. The developmental periods of the immature stages decreased with increasing temperature, but the larval period did not decrease further at 35℃. The pupal weight increased with increasing temperature, but the female weight decreased at 35℃. Variations with different last larval instars within the colonies at different temperatures were observed. Adults produced offspring at all tested temperatures. Adult longevity and the pre-oviposition and oviposition periods decreased with increasing temperature, but the pre-oviposition period increased at 33℃. Total fecundity exceeded 400 viable eggs at 22℃ and 31℃. The mean daily fecundity during the oviposition period and the mean daily fecundity on the day of oviposition increased with increasing temperature, but decreased at 33℃. Daily fecundity sharply increased at earlier adult ages and slowly decreased thereafter. The simulated oviposition frequency was greatest at 22℃. The lower developmental threshold temperatures were estimated to be the lowest at 9.7℃ for the first instar larva and the highest at 14.7℃ for the 5th to last instar larval stage, using a linear model.

Purpose : This study was Performed to identify the histopathologic feature by the reevaluation of the Pathologic specimen of the cervical tumors and to evaluate the clinical findings and the treatment results of the patients with small cell carcinoma of the cervix treated by radiotherapy. Materials and Methods : 2890 patients with cervical carcinoma received radiotherapy at the Department of Radiation Oncology. Yonsei Cancer Center, Yonsei University College of Medicine between October 1981 and April 1995. Of the 2890 patients in this data base, sixty were found to have small cell carcinomas $(2.08\%)$. Among them thirty six patients were transferred from other hospitals. the biopsy specimens of those Patients were not available. So we could review the slides of the other twenty four patients who were diagnosed at our hospital. Twenty four patients with small cell carcinoma of the cervix were analyzed retrospectively based on the assessment of H & E staining and other four immunohistochemical stains for neuroendocrine differentiation (neuron specific enolase, chromogranin. synaptophysin and Grimelius stain). And we also evaluate the Patients and tumor characteristics. response to radiation. patterns of failures, 5 year overall and disease free survival rates. Results : Thirteen tumors were neuroendocrine carcinomas(13/24 = $54.2\%$) and eleven tumors were squamous carcinomas, small cell type (11/24 = $47.8\%$) based on the assessment of H & E staining and other four neuroendocrine marker studies. So we classified the Patients two groups as neuroendocrine carcinoma and small cell type of squamous carcinoma, Among the 13 neuroendocrine carcinomas, five were well to moderately differentiated tumors and the other eight were Poorly differentiated or undifferentiated ones. The median age was 54 years old (range 23-79 years). Eight Patients had FIGO stage IB disease, 12 had stage 11, 3 had stage III and one had stage IV disease, Pelvic lymph node metastases were found in five Patients $(20.8\%)$. three of them were diagnosed by surgical histologic examination and the other two were diagnosed by CT scan. There was no difference between two histopathologic groups in terms of patients and tumor characteristics. response to radiation. 5 year overall and disease free survival rates. However the distant metastases rate was higher in neuroendocrine carcinoma Patients (6/13:$46.2\%$) than in small cell type of squamous carcinoma Patients (2/11:$18.2\%$), but there was no statistically significant difference because of the small number of patients (P>0.05). Conclusion : More than half of the small cell carcinoma of the cervix patients were neuroendocrine carcinoma (13/24 : $54.1\%$) by reevaluation of the biopsy specimen of the cervical tumors. The tendency of distant metastases of the neurolndocrine carcinoma was greater than those of the small cell type of squamous carcinoma $(46.2\%\;vs.\;18.2\%)$. But there were no differences in the patients and tumor characteristics and other clinical treatment results in both groups. These data suggest that radical local treatment such as radiotherapy or radical surgery combined with combination systemic cytotoxic chemotherapy might provide these patients with the best chance for cure.

The following conclusions were obtained after bibliographic investigation on the therapy of lung cancer by western, oriental, and integrated oriental and western medicine. 1. Lung cancer is classified into small cell lung cancer(SCLC) or non small cell lung cancer(NSCLC) in the treatment by western medicine, and applied with the means of surgery, radiotherapy and chemotherapy alone or combined, depending on the stage and the symptom. 2. Treatment by oriental medicine includes the means of strengthening body resistance to dispel pathogenic factors(扶正祛邪), combined approach of reinforcement and expulsion(攻補兼施), and reinforcing both qi and blood(氣血雙補), depending on the initial, middle, and terminal stage. And also treatment based on differentiation of symptom(辨證施治) is applied according to the type of symptom; deficiency of qi of both lung and spleen(肺脾氣虛), heat symptom of lung by deficiency of yin(肺熱陰虛), stagnation of damp-phlegm and blood(濕痰瘀阻), stagnation of qi and blood(氣血瘀滯), deficiency of both qi and yin(氣陰兩虛). Single or combined herb drug is used according to the symptom. 3. Treatment by integrated oriental and western medicine improved survival rate and quality of life. It promoted recovery and improved survival rate in the patients receiving surgery. Integrated radiotherapy and oriental medicine treatment reduced adverse effect by radiotherapy and improved therapeutic effect and survival rate. Integrated chemotherapy with oriental medicine treatment reduced side effect by chemotherapy and improved quality of life and survival rate. These results suggest that therapy of lung cancer should be applied with integrated oriental and western medicine from diagnosis to treatment for promoting therapeutic effect. And further study on this therapy should be ensued.

Fertilized eggs of red seabream, Pagrus major were subjected to cold shock with various initial treatment times and durations. Cold shocks at $3^{\circ}C$ for 20 minutes and 30 minutes at 6 minutes after fertilization yielded the highest triploid incidence with 100%. Triploidy was confirmed by erythrocyte measurements and chromosome counts. Diploid ad 48 acrocentric chromosomes. while triploid had 72 acrocentrics. Triploids revealed increased erythrocyte size compared to their diploids and early growth rates of triploids from 10 days to 34 days after hatching were slightly lower than that of their controls.

To induce an early spawning, the adult red sea bream, Pagrus major, were exposed to predesignated condition of photoperiod and water temperature during February 21 to June 30, 1988. Spawning began from April 20, a month earlier than that in the natural condition, when the photoperiod and water temperature were controlled at 14L: l0D and $17.0^{\circ}C$, respectively, and the spawning continued until June 15, 1988. There were no particular differences between fish under the controlled condition and those in natural condition in terms of the fertilization rate, surface floating rate, the number of oil glouble and the hatching rate.

Purpose : This study was tried to evaluate the Potential benefits of concurrent chemoradiation therapy (low dose daily cisplatin combined with split course radiation therapy) compared with conventional radiation therapy alone in stage III non-small cell lung cancer. The end points of analyses were response rate. overall survival, survival without locoregional failure, survival without distant metastasis, prognostic factors affecting survival and treatment related toxicities. Materials and Methods : Between April 1992 and March 1994, 32 patients who had stage III non-small cell lung cancer were treated with concurrent chemoradiation therapy. Radiation therapy for 2 weeks (300 cGy given 10 times up to 3000 cGy) followed by a 3 weeks rest period and then radiation therapy for 2 more weeks (250 cGy given 10 times up to 2500 cGy) was combined with $6mg/m^2$ of cisplatin. Follow-up period ranged from 13 months to 48 months with median of 24 months. Historical control group consisted of 32 patients who had stage III non-small cell lung cancer were received conventionally fractionated (daily 170-200 cGy) radiation therapy alone. Total radiation dose ranged from 5580 cGy to 7000 cGy with median of 5940 cGy. Follow-up Period ranged from 36 months to 105 months with median of 62 months. Result : Complete reponse rate was higher in chemoradiation therapy (CRT) group than radiation therapy (RT) group (18.8% vs. 6.3%, CRT group showed lower in-field failure rate compared with RT group(25% vs. 47%. The overall survival rate had no significant differences in between CRT group and RT group (17.5% vs. 9.4% at 2 years). The survival without locoregional failure (16.5% vs. 5.3% at 2 years) and survival without distant metastasis (17% vs. 4.6% at 2 years) also had no significant differences. In subgroup analyses for Patients with good performance status (Karnofsky performance scale 80), CRT group showed significantly higher overall survival rate compared with RT group (62.5% vs. 15.6% at 2 years). The prognostic factors affecting survival rate were performance status and pathologic subtype (squamous cell cancer vs. nonsquamous cell cancer) in CRT group. In RT alone group, performance status and stage (IIIa vs IIIb) were identified as a Prognostic factors. RTOG/EORTC grade 2-3 nausea and vomiting(22% vs 6% and bone marrow toxicities (25% vs. 15.6% were significantly higher in CRT group compared with RT alone group. The incidence of RTOG/EORTC grade 3-4 pulmonary toxicity had no significant differences in between CRT group and RT group (16% vs. 6%. The incidence of WHO grade 3-4 pulmonary fibrosis also had no significant differences in both group (38% vs. 25%. In analyses for relationship of field size and Pulmonary toxicity, the Patients who treated with field size beyond 200cm2 had significantly higher rates of pulmonary toxicities. Conclusion : The CRT group showed significantly higher local control rate than RT group. There were no significant differences of survival rate in between two groups. The subgroup of patients who had good performance status showed higher overall survival rate in CRT group than RT group. In spite of higher incidence of acute toxicities with concurrent chemoradiation therapy, the survival gain in subgroup of patients with good performance status were encouraging. CRT group showed higher rate of early death within 1 year, higher 2 year survival rate compared with RT group Therefore, to evaluate the accurate effect on survival of concurrent chemoradiation therapy, systematic follow-up for long term survivors are needed.

Although significant progress has been made in the surgical treatment of esophageal carcinoma as well as in the detection of early stage esophageal carcinoma by diagnostic techniques, the prognosis of the esophageal carcinoma patients remain poor. The p53 gene product is known to regulate cell growth and proliferation. And the nm23 gene was identified originally as an anti-metastatic influence whose expression was correlated inversely with tumor metastatic potential in murine melanoma cell lines. This experiment was intended to know the relationship among the p53 and nm23 gene expression versus clinicopahologic characteristics of the esophageal cancer. Total 40 cases were collected from patients who had undergone esophagectomy at St. Mary's Hospital, Catholic university of Korea. Immunohistochemical stain for p53 mutant-type protein and nm23 protein was graded as <10% positive tumor cells: negative; 10∼30% positive tumor cells: ＋ ; 30∼50% positive tumor cells: ＋＋, and >50% positive tumor cells: ＋＋＋. The tumor invasion was grades as none:－ ; mild:＋ ; moderate:＋＋ ; severe: ＋＋＋. Overexpression of p53 protein and nm23 was not associated with the survival and cliniocopathologic characteristics of the esophageal cancer. Moreover, the combination analysis of p53 and nm23 revealed that there was no relationship between the gene expression and the clinicopatholic characteristics of the esophageal cancer.

Doxorubicin is a general chemotherapy drug widely used for a number of cancers. However, the correlation between endogenous nitric oxide ($NO^{\bullet}$) levels and chemoresistance to doxorubicin remains unclear. In this study, we investigated the effect of endogenous $NO^{\bullet}$ on the anticancer activity of doxorubicin in human colon cancer cell lines HCT116 and HT29 with different p53 status. The cells were treated with either doxorubicin alone or in combination with the $NO^{\bullet}$ synthase (NOS) inhibitor $N^G$-monomethyl-L-arginine (NMA). Doxorubicin differentially inhibited the growth of both the HCT116 (p53-WT) and HT29 (p53-MUT) cells, which was mitigated by cotreatment with NMA. Further studies revealed that inhibition of endogenous $NO^{\bullet}$ mitigated doxorubicin-induced apoptosis in the HCT116 and HT29 cells, as evidenced by apoptotic DNA fragmentation and the sub-G1 peak of apoptotic markers. Apoptosis was delayed in the HT29 cells, and its magnitude was greatly reduced, underscoring the importance of the modulation of p53 in the response. RT-PCR analysis revealed that doxorubicin down-regulated levels of inhibitors of the apoptosis family (cellular IAP-1 and-2). Collectively, these data show that induction of apoptosis by doxorubicin in human colon cancer cells is possibly related to modulation of endogenous $NO^{\bullet}$, the expression of the IAP family of genes, and the status of p53. The underlying mechanisms may represent potential targets for adjuvant strategies to improve the efficacy of chemotherapy for colon cancer.

Recently, problems regarding marital adjustment of cancer patients are recognized as serious matter of concern for it had been reported that these issues have severe negative effects on relationship stability within marriage. It is noteworthy how marital adjustment is found to be critical for the cancer patient's mental stability, healing process and chances of survival as reported in the research. Thus, the ultimate goal of this research is to contribute to improvement of the stable relationship and also to formulate the social service related strategy for marriage adjustment for married cancer patient married couples in Korea. Actor and Partner Interdependence Model was formed in order to observe how the communication of the married couple affects marital adjustment and how this has an actor effect as well as partner effect. In order to authenticate this research model, dyadic data which sample the cancer patient and the spouse as a pair. Survey was conducted as the cancer patients who had been diagnosed with cancer and their respective spouses. The survey was taken from 160 married couples which totals to 320 people all together. Results indicated the cancer patient and the spouse have a significant relationship in marital adjustment. Through this, it had been concluded that marital adjustment is not separated but co-dependent with dynamic relationship. And the mutual constructive communication had proven to have a significant positive effect on one's marital adjustment. In demand-withdrawal communication, its negative effect on the self effect was found to be significant in both the patient and the spouse to both of their marital adjustment. Mutual avoidance communication had shown to only cause significant negative effect on self effect to the patient. In verifying the partner effect, significant negative effect was caused by patient's demand-withdrawal communication in partner effect on the spouse's marital adjustment. The results of this study are discussed in term of their implications for clinical interventions for the betterment of marital adjustment among cancer patients and their spouses. The suggestions for future research are discussed also.
