In our previous studies, we demonstrated that Vascular Endothelial Growth Factor (VEGF) enhances bovine oocyte maturation and early embryonic development in serum supplemented media. In this experiment, to determine the synergistic effect of VEGF with serum components on early embryonic development in vitro in cattle, 1 mg/ml polyvinyl-alcohol (PVA) was replaced with foetal bovine serum (FBS) in maturation and culture media. Bovine oocytes were matured in Synthetic Oviduct Fluid (SOF) supplemented with PVA, PVA+5 ng/ml of VEGF, FBS, or FBS+VEGF. Fertilized oocytes were cultured in the same conditions for 8 days. The development of embryos was examined at 48 h post- insemination and on days 6, 7 and 8. The results were analyzed using repeated measures two- factor ANOVA, in which the effects of VEGF and serum were assigned as two factors. The development rate to 4- to 8-cell embryos at 48 h was significantly higher in the PVA+VEGF group than in the PVA group (44.7% and 31.5%, respectively). However, the highest development rate to 4- to 8-cell embryos was obtained from the FBS+VEGF group (58.8%). On day 8, the blastocyst rates were higher in the PVA+VEGF (22.8%), FBS (32.1%, p<0.05) and FBS+VEGF (42.1%, p<0.05) groups than in the PVA group (17.1%). Two- factor ANOVA of the development rates indicates that VEGF had a significant effect, but had no synergistic effect with serum components on early embryonic development. The results of the present study demonstrate that VEGF improves the in vitro developmental competence of bovine oocytes and/or embryos independent of the effect of serum components.

Rainbow trout (Oncorhynchus mykiss) were treated with ultrasonic (40kHz) and microbubble. The organic serum components, glucose were decreased compared to control at microbubble single treatment (M) and ultrasonic treatment (UL), but glucose concentrations in fish serum of all experimental groups analyzed in this study were also within the normal range. The organic serum components, cholesterol and total protein were no significant change by ultrasonic and microbubble treatment. There were no significant changes in the lysozyme activity on ultrasonic and microbubble treatment. Serum bactericidal activity decreased on ultrasonic single treatment (UL) compared to the control (P<0.05), but the numbers of bacterial colonies were significantly lower than those in the negative (PBS). The results of this study indicate that ultrasonic and microbubble treatment did not have a critical effect on the serum composition and innate immunity of O. mykiss, and that it is a way to do not significant stress on the fish body as a countermeasure against sea lice.

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.

Serum protein and hemoglobin patterns were obtained by cellulose acetate electrophoresis for several anurans. Differences were found both in the number of components from individual animal hemoglobins and in the mobility of these components. Under the conditions employed, toad and R. plancyichosenica had a single component. Other frogs showed 2-component pattern. Sera of all anurans examined contain albumin but no preablumin. Relatively few assayable proteins are found in serum from B. buro gragraizans and differ thereby from most serum patterns examined for frogs, which show complex serum protein bands. Different species have dissimilar patterns although some of bands are apparently homologous between species.

For the study of the effect of dietary phospholipid (PL) on the lipid components of serum and organ tissues in Sprague-Dawley rats, 56 Male-rats were divided into 8 groups, which was composed of 7. One group was fed with basal diet (normal group). And other experimental groups were fed ad libitum with the mixture of carbohydrate. casein salt mixture : vitamin mixture(60:18:4:1) and at the same time fed administratively with 1 gram of phospholipid-free soybean oil, corn oil and sesame oil, and phospholipid-containing soybean oil, corn oil and sesame oil respectively After 60 days the rats were fasted for 12 hours and then decapitated to collect blood and separate organ tissues . The lipid and protein components of serum and organ tissues were analyzed. The results of this study are summarized as follows The supplementation of dietary phospholipid decreases the food efficiency ratio and the growth rate of experimental rats, it increases the level of serum phospholipid and cholesterol ester, but decreases the value of total-cholesterol (T-chol.)/PL ; it decreases the value of albumin/globulin (hyG ratio) of serum protein and it increases the level of phosphatidyl ethanolamine(PE) in serum and organ tissues. And the correlation coefficients among the contents of T-chol., of HDL-chol. and of phospholipid in serum and liver are negative in general. Therefore 1 think that we must eat dietary phospholipid unpurified from vegetable oil to prevent development of atherosclerosis and fat liver.

Since 1982, female agricultural workers are populous than male in Korea. Previous study was suggested that female workers are more sensitive to the agricultural medicine poisoning than male. This study was conducted with the aim of evaluating the impact on plasma components and nutrient intakes in female agricultural workers by the use of pesticides. Data were obtained from 44 females residing in Wonjoo, Kangwon-do area. Analysis for the general characteristics, nutrient intakes, and plasma components of the subjects were performed by physical examination, 24-hour recall method and venous blood sampling. They were divided into 3 groups according to the degree of the pesticide use: 8 in none(Non-expose group), 14 in low(<4/yr)(Low-expose group), and 22 in high$({\geq}4/yr)$(High-expose group). The results are summarized as follows. Serum glucose, SGOT, SGPT, triglyceride, HDL-cholesterol did not correlated with pesticide use and were not different among the groups. But serum total cholesterol was higher in pesticide use group. With increasing the number of pesticide use times, leukocyte count was tended to increased. Eighty two percent of the subjects were hemoglobin less than or equal to 12g/dl. Hematocrit, MCV, MCH, MCHC, serum Fe, Serum ferritin belonged to normal range and did not correlated with pesticide use. Intake of energy, Fe, vitamin $B_2$ were lower than RDA. Fe, K, and vitamin A intake were higher in don't use group than the other groups. There are not many differences according to using the pesticide in anthropometric measurements, nutrient intakes, and blood components, except for serum total cholesterol level and some nutrients intake. But these results suggest the need the systemic researches about the effects the pesticide using on nutritional status in Korean agricultural workers.

The principal objective of this study was to assess the effects of chitosan oligosaccharide supplementation on the improvement of blood glucose, lipid components and enzyme activities in the serum of streptozotocin(STZ, 55 mg/kg B.W., I.P. injection)-induced hyperglycemic rats fed on experimental diets for 5 weeks. The concentrations of blood glucose, total cholesterol, atherosclerotic index, LDL, LDL-cholesterol, free cholesterol, cholesteryl ester ratio, triglycerides(TG) and phospholipids(PL) in serum were remarkably higher in the hyperglycemic group(group BSW) and STZ(I.P.)+chitosan oligosaccharide supplementation group(group ECW) than those in the control group(group BW, basal diet+water). However the concentrations of blood glucose, total cholesterol, atherosclerotic index, LDL, LDL-cholesterol, tree cholesterol, cholesteryl ester ratio, TG and PL in serum were lower in the ECW group than in the BSW group, whereas the ratio of HDL-cholesterol concentration to total cholesterol and HDL-cholesterol concentration in the ECW group were higher than in the BSW group. The activities of alkaline phosphatase(ALP) and aminotransferase(AST, ALT) in serum were lower in the ECW group than in the hyperglycemic BSW group. The results shown above suggested that chitosan oligosaccharide supplementation effectively improves blood glucose, lipid composition and enzyme activities in the sera of STZ-induced hyperglycemic rats.

Background: We aimed to investigate candidates for serological biomarkers of neuropathic pain in individuals with neuromyelitis optica spectrum disorder (NMOSD). Methods: We analyzed 38 sera samples from 38 participants with NMOSD in National Cancer Center. Neuropathic pain was evaluated using the painDETECT questionnaire. Pain with neuropathic components (painDETECT score ≥ 13) was observed in 22 participants, among whom 17 had definite neuropathic pain (painDETECT score ≥ 19). The remaining 16 participants had non-neuropathic pain (painDETECT score < 13). Serum glial fibrillary acidic protein (GFAP) levels were assessed using a single-molecule array assay. Several cytokines, including tumor necrosis factor-alpha (TNF-α), interleukin (IL)-6, IL-10, and IL-17A, were measured by a multiplex bead-based immunoassay. Results: In comparison of NMOSD participants with neuropathic pain components (or definite neuropathic pain) and those with non-neuropathic pain, the absolute values of serum GFAP, TNF-α, IL-6, and IL-10 levels were higher in participants with neuropathic pain components (or definite neuropathic pain), but these findings did not reach statistical significance. Conclusions: Further larger-scale investigations to find reliable serological biomarkers for neuropathic pain in NMOSD are warranted.
