Objective: To observe the efficacy and toxicity of nanoparticle albumin bound paclitaxel (nab-paclitaxel) plus platinum agent (cisplatin or carboplatin) as first line treatment for stage III/IV squamous non-small-cell lung cancer (NSCLC). Methods: Forty chemotherapy naive patients with stage III/IV squamous NSCLC received nab-paclitaxel $125mg/m^2$ on day 1 and day 8, cisplatin $75mg/m^2$ on day 1, carboplatin area under the concentration-time curve of 5 (AUC=5) on day 1. One cycle of treatment was 3 weeks, and at least two were completed in each case. Results: Of the 40 patients who participated in the study, 25 achieved partial responses (PR), 12 reached a stage of stable disease (SD), and 3 suffered progressive disease (PD). The overall response rate (ORR) was 62.5% and the disease control rate (DCR) was 92.5%. Of the 20 patients without surgery or radiotherapy, 10 achieved PR, 7 reached a stage of SD, and 3 PD. The ORR was 50.0% and the DCR was 85.0%. The median progression-free survival time (PFS) of patients without surgery or radiotherapy was 5.0 months. Of the 20 patients receiving surgery or radiotherapy, 15 had PR and 5 p had SD, with an ORR of 75.0% and a DCR of 85.0%. Specifically, the DDP arm demonstrated a significantly higher ORR than the CBP arm (100%vs 54.5%, P<0.05). Common treatment related adverse events were myelosuppression, gastrointestinal response, baldness and neurotoxicity, most of which were grade 1 to 2. Conclusion: Nab-paclitaxel plus platinum agent (cisplatin or carboplatin) is effective as a first-line chemotheraphy for stage III/IV squamous NSCLC, and its adverse effects are tolerable.

Mineralization of Daehwa and Donsan W-Mo deposits can be devided into three distinct depositional stages on the basis of mineral paragenesis and flnid inclusion studies; stage I, deposition of oxides and silicates ; stage II, deposition of base-metal sulfides and sulfosalts with carbonates; stage III, deposition of barren calcite and fluorite. Tungsten, molybdenum and tin mineralization occurred in stage I. Fluid inclusion studies reveal that ore fluid of stage I were homogeneous $H_2O-CO_2$ fluids containing 3.5~14.6 mol % $CO_2$. Minimum temperature and pressure of stage I ore fluids were $240^{\circ}C$ and 500 bars respectively. Salinities of aqueous type I inclusions in minerals of stage I range from 3.7 to 7.6 wt. % equi. NaCl. whereas those of $CO_2$-containing type III inclusions range from 0.3 to 4.4 wt. %. Temperatures of stage II ore fluids range from 200 to $305^{\circ}C$ on the whole and salinities were in the range of 3.2~7.2 wt. %. Homogenization temperatures of fluid inclusions in calcite and fluorite of stage III range from 114 to $186^{\circ}C$ and salinities were in the range of 0.9~4.3 wt. %. Sulfur fugacities during stage II deduced from mineral assemblages and tamperature data from fluid inclusions declined from earlier to later in the range of $10^{-11}{\sim}10^{-18}atm$. Fluid inclusion evidences suggest that the dominance of $CO_2$ in ore fluid during W-Mo mineralization is the characteristic features of Cretaceous W-Mo deposits of central district of Korea compared to those of Kyeongsang basin district.

226 patients with carcinoma of the uterine cervix treated with curative radiation therapy at the Department of Therapeutic Radiology, Dongsan hospital, Keimyung university, School of medicine, from July,1988 to May,1991 were evaluated. The patients with all stages of the disease were included in this study. The maximum and mean follow up durations were 60 and 43 months. The radiation therapy consisted of external irradiation to the whole pelvis (2700~4500 cGy) and boost parametrial doses (for a total of 4500~6300 cGy)with midline shild $(4{\times}10\;cm),$ and combined with intracavitary irradiation (5700~7500 cGy to point A). The distribution of patients according to the stage was as follows: stage IB 37 $(16.4\%),$ stage IIA 91 $(40.3\%),$ stage IIB 58 $(25.7\%),$ stage III 32 $(13.8\%),$ stage IV 8 $(3.5\%).$ The overall failure rate was $23.9\%$ (54 patients). The failure rate increased as a function of stage from $13.5\%$ in stage IB to $15.4\%$ in stage IIA, $25.9\%$ in stage IIB, $46.9\%$ in stage III, and $62.5\%$ in stage UV. The pelvic failure alone were 32 patients and 11 patients were as a components of other failure, and remaining 11 patients had distant metastasis only. Among the 43 patients of locoregional failure,28 patients were not controlled initially and in other words nearly half of total failures were due to residual tumor. The mean medial paracervical (point A) doses were 6700 cGy in stage IIB,7200 cGy in stage IIA,7450 cGy in stage IIB,7600 cGy in stage III and 8100 cGy in stage IV. The medial paracervical doses showed some correlation with tumor control rate in early stage of disease (stage Ib, IIA), but there were higher central failure rate in advanced stage in spite of higher paracervical doses. In advanced stage, failure were not reduced by simple increment of paracervical doses. To improve a locoregional control rate in advanced stages, it is necessary to give additional treatment such as concomitant chemoradiation.

Purpose: This study was performed to evaluate three-dimensional positional change of the condyle using 3D CT after bilateral sagittal split ramus osteotomy (BSSRO) in skeletal class III patients. Patients and methods: Nine patients who underwent BSSRO for mandibular set-back in skeletal class III malocclusion without facial asymmetry were examined. Miniplates were used for the fixation after BSSRO. 3-D CT was taken before, immediately after, and 6 months after undergoing BSSRO. After creating 3D-CT images using V-works $4.0^{TM}$ program, axial plane, coronal plane, & sagittal plane were configured. Three dimensional positional change, from each plane to the condyle, of the nine patients was measured before, immediately after, and 6 months after undergoing BSSRO. Results: 1. The mean value of mandibular set-back for nine mandibular prognathism patients was 7.36 mm (${\pm}\;2.42\;mm$). 2. In the axial view, condyle is rotated inward immediately after BSSRO (p < 0.05), comparing with preoperative but outward 6 months after BSSRO comparing with postoperative (p < 0.05). 3. In the axial view, condyle is moved laterally immediately after BSSRO (p < 0.05), comparing with preoperative but regressed 6 months after BSSRO comparing with preoperative (p > 0.05). 4. In the frontal & coronal view, there is changed immediately after and 6 months after BSSRO, comparing with preoperative but no statistical difference. Conclusion: These results indicate that three-dimensional positional change of the condyle in skeletal class III patients is observed lateral displacement & inward rotation immediate after BSSRO, but the condyle in 6 months after BSSRO tends to regress to preoperative position.

Though the endometriosis is not always related with infertility, endometriosis causes infertility in some patients. There are many treatment modalities of infertile patients who have endometriosis. In recent years, Assisted Reproductive Technology(ART) have been widely accepted as being a useful tool for the treatment of infertile endometriotic patients. The objective of this study was to evaluate the outcome of ART in infertile endometriotic patients who have been carried out IVF-ET from Jan, 1992 to Dec, 1994 and to compare the results between COH/IUI and IVF-ET in the patients with endometriosis stage I. Tubal disease only patients were grouped(308 patient, 956 cycles) as a control. Endometriosis group was subdivided into 4 groups according to American Fertility Society classification; endometriosis stage I (45 patients, 61 cycles), stage II (26 patients, 39 cycles), stage III (26 pateitns, 37 cycles), stage IV (33 patients, 50 cycles). The outcomes of IVF-ET in endometriosis patients were as follows; The oocyte recovery rates were significantly lower in stage III, IV endometriosis. In case of stage III endometriosis, the fertilization rate was significantly lower than other stages of endometriosis. Clinical pregnancy rates per cycle were not different between the tubal group(22%) and the endometriosis group(25%). According to endometriosis stage, the implantation rate and clinical pregnancy rate were significantly lower in stage IV (5.6%, 16%) compared with other stages (I; 10.0%, 26%, II;9.8%, 31%, III;12.6%, 32%). It suggests that some factor like autoantibodies may inhibit implantation of embryos in stage IV endometriosis. To evaluate the possibility that simply increasing the number of gametes at the site of fertilization might account for pregnancies attributed to IVF-ET, the authors retrospectively analyzed the outcome of couples undergoing IUI during hMG cycles and CC cycles between 1992 and 1994 in the women with endometriosis stage 1. In case of stage I endometriosis, though the COH/IUI group showed lower FSH level and lesser age profile than IVF-ET group, IUI group has resulted in lower pregnancy rates(19.2%) compared with the IVF-ET group(26.2%). In conclusion, endometriotic infertile patients can get comparable pregnancy rates with the tubal factor infertility patients during IVF-ET program. Moreover even in stage I endometriosis, IVF-ET may be an more effective treatment modality than COH/IUI.

Stage of cervical cancer may adversely affect the quality of life (QOL) among patients. The objective of this study was to predict the QOL among cervical cancer patients by the stage of their cancer. A cross-sectional study from September 2012 until January 2013 was conducted among cervical cancer patients who completed treatment. All patients completed a interviewer-guided questionnaire comprising four sections: (A) socio-demographic data, (B) medical history, (C) QOL measured by general health status questionnaire (QLQ-30) and (D) cervical cancer specific module CX-24 (EORTC) was used to measured patient's functional, symptom scale and their global health status. Results showed that global health status, emotional functioning and pain score were higher in stage III cervical cancer patients while role functioning was higher in stage I cervical cancer patients. Patients with stage IV cancer have a lower mean score in global health status (adjusted b-22.0, 95 CI% -35.6, -8.49) and emotional functioning (adjusted b -22.5, 95CI% -38.1, -6.69) while stage III had lower mean score in role functioning (adjusted b -14.3, 95CI% -25.4, -3.21) but higher mean score in pain (adjusted b 22.1, 95 CI% 8.56, 35.7). In conclusion, stage III and IV cervical cancers mainly affect the QOL of cervical cancer patients. Focus should be given to these subgroups to help in improving the QOL.

This study was carried out to assess the reproductive toxicity of 2-bromopropane (S-BP) using spermatogenesis stage classification and Sertoli cell indices (SCI).Vehicle control olive oil and 2-BP doses of 125, 250 and 500 mg/kg of body weight were injected in the interaperitoneum of 12 weeks male Sprague-Dawley rats for 28 days respectively of SCI on germ cells including the spermatogonia of stages II-III, Ⅵ,Ⅹ, XII, ⅩIII, and spermatocytes of stages VIII (preleptotene), Ⅹ (leptotene), XII (leptotene), V and Ⅵ (pachytene), and the round spermatids of stage Ⅵ. Considering the process of maturation depletion in spermatonesis, spermatogonia may be the primary target cells of 2-BP toxicity.

The ore deposit of the Ohtani mine is one of representatives of plutonic tungsten-tin veins related genetically to acidic magmatism of Late Cretaceous in the Inner zone of Southwest Japan. Based on macrostructures of vein filling, three major mineralization stages are distinguished by major tectonic breaks. The constituents of ore minerals are scheelite, cassiterite, chalcopyrite, pyrrhotite, sphalerite, with small amounts of cubanite, stannite, galena, native bismuth, bismuthinite, arsenopyrite and pyrite. The relationship between the polymorphic variations of pyrrhotite and the kinds of the associated characteristic of ore mineral, in relation with hypogene mineralization, has been demonstrated. Pyrrhotite of stage I is predominantly of the hexagonal phase (Hpo>Mpo). Pyrrhotite of stage II is mainly of the monoclinic phase ($Hpo{\ll}Mpo$). Pyrrhotite of stage III is a single monoclinic phase ($Hpo{\ll}Mpo$). The compositions of the hexagonal pyrrhotite decrease in Fe content ranging from 47.44 atom % Fe in stage I to 46.88 atom % Fe in stage III.

Freshly harvested American ginseng (Panax quinquefolium L.) seeds were stratified at two locations over each of three years. Seed development and temperature in the stratification boxes were investigated until the seed was removed 12 months later and direct-seeded in the field. During stratification and seeding (14 months) three embryo stages were identified. In Stage I of 250 days (Sept. to mid-May) embryo length increased from about 0.5 to 1.0 mm: in Stage II of 100 days (mid-May to late Aug. when seeded) length increased to 2.0 mm and in Stage III (late Aug. to late Nov.) length increased to 5.3 mm. Excerpt split width could also be placed in three stages. Changes in embryo length correlated with embryo endosperm length ratio. Insertion compression tests showed that the excerpt softened rapidly in late Stage II and throughout Stage III. The stratification box temperatures at all depths (10, 25 and 50 cm) never exceeded -2$^{\circ}C$ even when the air temperatures dropped to -13$^{\circ}C$ and were, therefore not damaging to the seeds.
