Objective: The aim of this study was to explore change and significance of serum carcino-embryonic antigen (CEA) before and after gefitinib therapy in patients with advanced non-small-cell lung cancer (NSCLC). Methods: Forty patients with advanced NSCLCs in III~IV stages were selected as study objects given gefitinib therapy combined with routine local radiotherapy until tumor progression or intolerable toxicity. After treatment, all patients were divided into control and non-control groups according to the results of evaluation based on RECIST 1.1 (Response Evaluation Criteria in Solid Tumors in 2009). Peripheral fasting blood from all patients was collected in the early morning and serum CEA was assessed by electro-chemiluminescence immunoassay (ECLIA) before and after treatment. Before treatment, patients were divided into high CEA group (CEA level > 50 ng/mL) and low CEA group (CEA level ${\leq}$ 50 ng/mL). Adverse reactions were noted and progression-free survival (PFS) in both groups was recorded after long-term follow-up that ended in December, 2012. Results: There was no difference between control and non-control groups in CEA level before treatment (P>0.05), whereas serum CEA decreased more markedly lower in the control group after treatment (P<0.01). All patients were divided into high CEA group (26) and low CEA group (14) according to serum CEA level. There was no statistically significant difference between two groups in adverse reactions (P>0.05) but the rate in former group was lower. Additionally, survival rates at 9 and 12 months in high CEA group were clearly higher than in the low CEA group (P<0.01). Conclusions: Serum CEA level can serve as a biochemical index to evaluate the prognosis with gefitinib treatment for NSCLC.

Bovine respiratory syncytial virus (BRSV) and bovine viral diarrhea virus (BVDV) are the main viral contributors to bovine respiratory disease (BRD) with high mortality and morbidity. BRD control measures include vaccination that modulates immunological profiles reflected in blood cells, serum, and body secretions, such as milk. This study evaluated the immune responses to an inactivated BRD vaccine in lactating cows reared in a natural environment on a dairy farm. The cows were intramuscularly inoculated with the vaccine, and serum, blood, and milk were collected pre-and post-vaccination. Our study revealed a prominent increase in BRSV-specific antibodies both in serum and milk, while the change in BVDV-specific antibodies was insignificant. Serum interleukin (IL)-1β and IL-6 levels significantly decreased, but this change was not reflected in milk. Evaluation of pattern recognition receptors (PRRs) via RT-qPCR revealed downregulation of nucleotide-binding oligomerization domain 2 (NOD2). The concentrations of BRSV antibodies, BVDV antibodies, IL-2, and IL-17A in serum and milk were strongly correlated, implying a concurrent influence on both body fluids. Thus, immunological factors modulated as a result of vaccination generally measured in serum were reflected in milk, demonstrating the suitability of milk evaluation as an alternative approach for immunological observations. Furthermore, the correlation between BRSV antibodies and NOD2 and that between BVDV antibodies and toll-like receptor (TLR) 2, TLR3, TLR4, and TLR5 imply the possible role of PRRs for the assessment of the immune response developed in immunized cows reared on the farm.

In recent years with development of immuno-electrophoresis, more acurate analysis of the serum protein became possible. However, there is few reports in the literature which investigated the changes of the immunoglobulin compared with electrophoretically fractioned serum thyroglobulin in the patients with various thyroid diseases. The purpose of this report is to investigate the changes of thyroglobulin in various thyroid diseases by the method of immuno-electrophoresis and to compare the results with.serum protein fractionated by the method of agar-gel micro-electrophoresis. Materials and Methods: Sera from 9 patients with diffuse toxic goiter, 2 nodular nontoxic goiter, 2 thyroiditis, 3 hypothy, roidism, 1 thyroid cancer, 7 cystic degeneration of the thyroid gland, and 10 normal subject were taken. All cases were confirmed by various laboratory thyroid function tests and thyroid needle biopsy. Immuno-electrophoretic analysis of the serum were performed by Scheidegger's modified micro-immuno-electrophoretic method. The antiserum was obtained from the Travenol Laboratories International, Hyland Products Division and was rabbit anti-human thyroglobulin. Microscope slide agar-gel electrophoresis for serum protein fractionation was performed at $4^{\circ}C$ using veronal buffer, pH 8.6 and ionic strength 0.05, with 54 volts and 2.8 mA for 60 minutes. The fractionated slide was stained with 0.1% thiazine red. The results were as follows: 1) Increase of immune-globulin macroglobulin (IgM), alphaglobulin, and immune-globulin A (IgA) by 95.8%, 100%, 29.2% respectively was found in the serum from various thyroid diseases. 2) Thyroglobulin fraction was found to be increased in 50%, no change in 41.7%, and no line in 8.3% with all of the various goiter patients. On the other hand, 10 normal control group showed only 2 cases of increase, 5 cases of no change and 3 cases of no line.

Objectives: Taxi drivers are exposed to various hazards, such as long periods of sedentary work and traffic-related air pollutants. However, studies on the health effects among taxi drivers in South Korea are insufficient. Methods: To assess subclinical hematologic change related to cardiovascular disease among male taxi drivers, we analyzed data from the second Korean National Environmental Health Survey. Fifty-nine taxi drivers and 1,912 controls were included in the analysis. Propensity score matching was performed to adjust for age, body mass index, and urinary cotinine. A total of 295 subjects were matched with 59 taxi drivers. Leukocyte count, platelet count, hematocrit, triglyceride, total cholesterol, HDL cholesterol land total IgE of the taxi drivers were compared with the control groups. Results: Taxi drivers showed significantly elevated blood leukocytes and platelets. Serum total IgE was significantly reduced in taxi drivers. However, blood leukocytes, platelets, and serum total IgE were not significantly correlated with work period among taxi drivers. Conclusions: Regarding the change of the blood leukocyte count, platelet count, and serum total IgE, taxi driving has the possibility to be associated with peripheral inflammation, humoral immunity and cardiovascular risk.

Serum lipid levels and fatty acid composition of serum phospholipids(PL) were investigated in 24 healthy male subjects who consumed either corn oil(CO) rich In linoleic acid(LA), perilla oil(PO) rich in $\alpha$-linolenic acid($\alpha$-LNA), or canola oil acid(OA) as a major fat source fir 5 weeks. The PO and the CNO groups showed significant(P <0.05) increases in serum high density lipoprotein-cholesterol(HDL-C) levels and in ratios of HDL- C/total cholesterol(TC) compared with initial values measured at the beginning of the study. Significantly(p <0.05) increased concentrations of serum triglycerides(TG) ware observed after 5 weeks of the CO based diet compared with both its intial value and the concentration observed after 5 weeks with the PO-based diet. fatty acid composition of serum PL reflected changes in dietary fatty acid composition and metabolism. Compared with the initial levels, significandy increased contents of eicosapentaenoic acid(EPA) and docosahexaenoic acid(DHA) were observed in serum PL of the PO group and significantly increased contents of $\alpha$-LNA and EPA were observed in the CNO group. Arachidonic acid(AA) content of serum PL did not change in the CO group during the study period, although, the increase in LA was significant(P <0.05). Compared with the CO-based diet, both the PO and the CNO-based diets seem to have beneficial effects on atherosclerosis by influencing the serum lipid profile and fatty acid composition of serum PL.

Low power laser and neuromuscular electrical stimulation have been utilized in many clinical applications for the treatment of musculoskeletal lesion. This study was to investigate the effects of low power He-Ne IR laser and neuromuscular electrical stimulation on the change of the serum biochemical components in experimentally induced muscle injured rats. The twenty Sprague-Dawley male rats were randomly assigned to the 4 groups: the normal group (n=5), the control group (n=5), the low power laser irradiation group (LLI) (n=5) and the neuromuscular electrical stimulation group (NMES) (n=5). The experimentally induced muscle injury was induced by the subcutaneous injection of a 0.1 ml Freund's Complete Adjuvant into the right hind paw and calf muscles in control, LLI and NMES groups. The LLI group was irradiated with He-Ne IR laser for 5 minutes every day during 10 days. Also, the NMES group was electrically stimulated 15 minutes every day during 10 days. The normal and control groups were not received with any therapeutic intervention. The authors performed tests which were the concentration of the serum biochemical components to detect the effects of therapeutic interventions. The results were as follows: 1. The level of the aspartate aminotransferase (AST) was significantly decreased in the LLI and NMES groups compare to the control group. 2. The level of the serum lactate dehydrogenase (LDH) was significantly decreased in the LLI and NMES groups compare to the control group. 3. The level of the serum creatine kinase (CK) was significantly decreased in the LLI and NMES groups compare to the control group. From the results, we could come to the conclusion that low power laser and neuromuscular electrical stimulation could be accelerating healing processes of skeletal muscle injury and further clinical work will be required.

Objectives: Recently, angiogenesis has gained an increasing interest as a prognostic factor in breast cancer. In this study we aimed to assess the anti angiogenic effects of HAD, a botanical anticancer remedy which has been prescribed in Daejeon University Oriental Hospital in Korea, on patients with breast carcinoma by measuring the serum vascular endothelial growth factor (VEGF), basic fibroblast growth factor (b-FGF) and platelets levels. Methods: The study included 26 consecutive breast cancer patients (mean age$\pm$standard deviation: 47.5$\pm$8.7 years) with stage II to IV disease who were treated with HAD (mean duration $\pm$ standard deviation: 264.5$\pm$121.6 days). In addition to routine laboratory and staging procedures, serum VEGF, b-FGF levels and platelet counts were determined as antiangiogenic markers. The antiangiogenic effects of HAD were evaluated by analyzing the differences between the values of the antiangiogenic markers before and after the treatment with HAD. Results: Serum b-FGF concentrations were significantly reduced after the treatment with HAD (P=0.042). Serum VEGF concentrations were found to have a somewhat decreasing change, though the change was not statistically significant (P=0.229). Platelet counts had little changes (P=O.80). Conclusions: It is supposed that HAD has effects on decreasing the serum b-FGF levels related with the clinical outcome of breast cancer patients.

The aim of the study was to determine whether vitamin E supplementation in three experimental model rats with impaired glucse tolerance could change serum insulin concentration and lipid distribution. The three groups were adult(AS) and neonatal (NS) streptozotocin-induced groups, and a high sucrose diet(HS) group. Each group was divided into control and vitamin E supplementatino groups at the age of 9 weeks. The level of vitamin E supplementation was 5g/kg diet. Blood and organ samples were taken at 5 and 10 weeks and were examined for changes in the level of serum insulin, glucose, lipids, liver lipids, and oxidative status. Vitamin E supplementation significantly reduced serum insulin in the HS group and caused the significant beneficial changes in serum lipids and triglycerides in As grouop at 10 weeks . In all groups, serum vitamin E was increased and malondialdehyde(MDA) in serumand liver were decreased significantly by vitamin E supplementation. The results suggest that vitamin E supplementation improves lipid distribution in adult streptozotocin-induced rats and serum insulin concentration in high sucrose diet-induced rats. Vitamin E might prevent on reduce oxidative injury in all experimental model rats with impaired glucose tolerance.
