This study was designed as a part of efforts to investigate the biochemical pollutant markers for diagnosis of maine pollutions by changes in cholinesterase activity of the flounder (Paralichthys olivaceus)in Yellow Sea of Korea. Acetylcholinesterase (AChE) activities in brain and muscle of cultured flounders in Yellow Sea were remarkably lower (40-50% and 40-55%, respectively)than those of wild flounder in Pohang (control) of East Sea, but AChE activities in brain and muscle of wild flounders in Yellow Sea were significantly lower(15-40% and 25-35%, respectively)than those of wild flounder in Pohang of East Sea. Butyrylcholinesterase(BChE) activities in barin and muscle of cultured flounders in Yellow Sea were remarkably lower(70-75% and 65-75%, respectively) than those of wild flounder in Pohang of East Sea, but BChE activities in barin and muscle of wild flounders in Yellow Sea were significantly lower (15-40%and 25-35%, respectively)than those of wild flounder in Pohang of East Sea. Lactate dehydrogenase (LDH) activities in serum of cultured flounders in Yellow Sea were significantly 10-50% higher than those of wild flounder in Pohang of East Sea, but LDH activities in serum of wild flounders in Yellow Sea were significantly 20-25% higher than those of wild flounder in Pohang of East Sea. It suggests that AChE and BChE activities in brain and muscle of cultured and wild flounders of Yellow Sea may be used as the most effective mean in a biochemical markers for diagnosis of pollutant effects by organophosphorus pesticides.

The A-type lamin deficient mouse line ($Lmna^{-/-}$) has become one of the most frequently used models for providing insights into many different aspects of A-type lamin function. To elucidate the function of Lmna in the growth and metabolism of mice, tissue growth and blood biochemistry were monitored in Lmna-deficient mice, heterozygous ($Lmna^{+/-}$) and wide-type ($Lmna^{+/+}$) backcrossed to C57BL/6 background. At 4 weeks after birth, the weight of various organs of the $Lmna^{-/-}$, $Lmna^{+/-}$ and $Lmna^{+/+}$ mice was measured. A panel of biochemical analyses consisting of 15 serological tests was examined. The results showed that Lmna deficient mice had significantly decreased body weight and increased the ratio of organ to body weight in most of tissues. Compared with $Lmna^{+/+}$ and $Lmna^{+/-}$ mice, $Lmna^{-/-}$ mice exhibited lower levels of ALP (alkaline phosphatase), Chol (cholesterol), CR (creatinine), GLU (glucose), HDL (high-density lipoprotein cholesterol) and higher levels of ALT (alanine aminotransferase) (p<0.05). $Lmna^{-/-}$ mice displayed higher AST (aspartate aminotransferase) values and lower LDL (lowdensity lipoprotein cholesterol), CK-MB (creatine kinase-MB) levels than $Lmna^{+/+}$ mice (p<0.05). There were no significant differences among the three groups of mice with respect to BUN (blood urea nitrogen), CK (creatine kinase), Cyc C (cystatin C), TP (total protein), TG (triacylglycerols) and UA (uric acid) levels (p>0.05). These changes of serological parameters may provide an experimental basis for the elucidation of Lmna gene functions.

This experimental study was designed to investigate the effects of Seunggijoui-tang on the weight of obese rats induced by high fat diet. A series of experiments have been conducted in order to measure the effects of above the body weight, serum and fat cell. The measurements have been performed on; (1) the increasing amount of body weight; (2) the quantity of total cholesterol, triglyceride, free fatty acid, total lipid, phospholipid, HDL-cholesterol and LDL-cholesterol in serum; (3) the size of the epididymal fat cell and the fat drops area in hepatic lobule. In the SG I (Group fed high fat diet and administered 42.5mg/100g extract of Seunggijoui-tang during 8 weeks), the weight decreased significantly throughout the whole research period. In the SG I & SG II (Group fed high fat diet and administered 85mg/100g extract of Seunggijoui-tang during 8 weeks), the serum total cholesterol, triglyceride, total lipid, phospholipid, LDL-cholesterol decreased significantly in comparison with control group. In the SG I, the serum free fatty acid decreased significantly in comparison with control group. In the SG I & SG II, the serum HDL-cholesterol decreased in comparison with control group, but this result showed no efficacy. In the SG I, the epididymal fat cell decreased significantly in comparison with control group. In the SG II, the fat drops area in hepatic lobule of rats decreased significantly in comparison with control group. Based on the above result, it is assumed that the clinical application of Seunggijoui-tang can help the treatment of obesity.

To elucidate the effects of an obesity control program on body composition and serum lipid levels, 31 obese elementary students (male: 25, female: 6) residing in the Gyeonggi area were evaluated and their body composition, serum total cholesterol, HDL-cholesterol, LDL-cholesterol and TG (triglyceride) were analyzed. The average age, height, weight and BMI (body mass index) were $11.52{\pm}1.00\;yrs$, $151.96{\pm}8.04\;cm$, $68.21{\pm}9.03\;kg$ and $29.40{\pm}1.79\;kg/m^2$ for the males, respectively, and $11.17{\pm}1.17\;yrs$, $147.83{\pm}5.15\;cm$, $65.05{\pm}10.86\;kg$ and $29.62{\pm}3.24\;kg/m^2$ for the females, respectively. There was a significant decrease in BMI for males (p<0.001) and females (p<0.05). There were also significant changes in all of the biochemical levels evaluated before and after the study. Specifically, the total cholesterol, LDL-cholesterol and TG level decreased after the obesity control program, while the HDL-cholesterol level increased after the program. These results indicate that obesity control programs do change the BMI, serum total cholesterol, HDL-cholesterol, LDL-cholesterol and TG levels in obese elementary students. Thus, obesity control programs are urgently needed to prevent degenerative disease and decrease obesity among children in elementary school.

A study detennined whether certain biochemical and physiological variables were altered during marginal Zn deficiency. Ten weaned crossbred Hereford Angus heifer calves, weighing $163{\pm}2kg$, were utilized. Five calves were fed a Zn - deficient (- Zn) brome-alfalfa hay diet containing 17 mg Zn/kg diet DM, and five calves were fed a Zn-adequate (+Zn) diet with 23 mg Zn/kg diet DM from $ZnSO_4$ added to the - Zn diet (total diet, 40 mg Zn/kg diet DM), for 32 d. At 21 d the - Zn calves had a reduction (p < .05) in feed efficiency. By 25 d, plasma Zn and alkaline phosphatase concentrations were reduced (p < .05) in the - Zn calves. Blood urea nitrogen, glucose, insulin, IGF-I, Cu plasma concentration and Zn and Cu concentrations of red blood cell (RBC) and liver were not altered (p > .05) by the - Zn diet through 25 d. In response to a single i. m. injection of dexamethasone (20 mg) on d 25, calves fed the two dietary Zn amounts showed no changes (p > .05) in plasma or RBC Zn and Cu concentrations, serum IGF-I, insulin, and glucose when measured at 6, 12, 24, 48, 72, and 96 h after injection. In response to an intradermal injection of phytohemagglutinin on d 30, cell mediated immune (CMI) response was reduced (p < .05) in the - Zn calves. These observations indicate that during a marginal Zn deficiency in calves, there was a decrease in feed efficiency, plasma Zn, serum alkaline phosphatase, and CMI response.

BACKGROUND/OBJECTIVES: Enteral nutrition formulas with immune-enhancing nutrients, such as n-3 fatty acids, may manage patients' nutritional status and pathophysiological processes. The aim of our study was to investigate natural killer (NK) cell activity alterations and related cytokine changes resulting from feeding with soybean oil-containing enteral nutrition formula (control group) and plant-derived n-3 fatty acid-enriched enteral nutrition formula. SUBJECTS/METHODS: Subjects participated for 14 consecutive days and consumed enteral formula containing canola and flaxseed oil (n3EN, test group) in nonsurgical patients hospitalized for rehabilitation. Blood samples were collected on the first day and 14 days after the consumption of each formula daily, and anthropometric parameters were collected. Hematology and biochemical values were analyzed, and NK cell activities and serum cytokine concentration were measured. A total of sixty subjects were included in the analysis, excluding dropouts. RESULTS: No significant differences were found in biochemical parameters. The n3EN group's NK cell activities at effector:tumor cell ratios of 10:1, 5:1, 2.5:1 and 0.625:1 were significantly higher than those of the control group after two weeks (P < 0.05). However, there were no statistically significant differences in serum cytokine interleukin (IL)-12, $interferon-{\gamma}$, $IL-1{\beta}$, IL-6 and tumor necrosis $factor-{\alpha}$ values between the two groups. CONCLUSIONS: In conclusion, this study elucidates the beneficial effects of plant-derived n-3 fatty acid supplementation in enteral formula on NK cell activity.

This study was undertaken to know the effect of fat diet (for eight weeks) on changes of inflammatory markers [tumor necrosis factor (TNF-${\alpha}$) and prostaglandin $E_2$ ($PGE_2$)] and blood coagulation system [platelet aggregation function (PAF), prothrombin time (PT), activated partial thromboplastin time (aPTT)] in rats. Serum TNF-${\alpha}$, $PGE_2$, biochemical markers, PAF, PT, aPTT, and body weight were measured and compared between the control (normal diet-rats) and the fat group (fat diet-rats). The weights in the fat group were higher than those of the control group. TNF-${\alpha}$, $PGE_2$, glucose, aspartate aminotransferase (AST), alanine aminotransferase (ALT), and creatinine levels were greater in the fat group compared with the control group. The degree of platelet aggregation was lower, whereas PT and aPTT levels were longer in the fat group than in the control group. These findings have shown that fat diet may cause inflammatory response, diabetes, liver and renal dysfunction, and disturbances of fibrinolysis and coagulation system.
