In this study, we investigated the effects of ostrich extract combined with Korean herb medicine(OEKHM) on the serum parameters in carageenan induced paw edema in rats. Carageenan causes enhanced edema formation which contributes to the pathophysiology of inflammation. Male Sprague-Dawley rats were used. There were four groups of treatments: OEKHMs and the control. After treatment with oral doses of 3 mL/180 g BW. 3 kinds of OEKHMs were processed which were ostrich bone with flesh meat with herb medicine(BFH), ostrich bone with flesh meat(BF), and ostrich bone with internal organs(BI). The contents of crude fat of the BFH was lower, but crude protein and crude ash of the BFH were significantly higher than those of the BF and the BI. In case of the levels of minerals(Ca, P, Mg, Fe, Cu and Zn ) of the BFH were significantly higher than those of BF and BI. And the heavy metals(Pb and Cd) were not detected in the OEKHM. The serum level of triglyceride in the BFH treated group decreased compared to that of the edema induced group. The serum levels of HDL-cholesterol concentration in the BFH supplemented group increased compared to that of the other groups. The serum levels of minerals(Ca, Mg, Fe, Cu and Zn) of the BFH treated group significantly increased than those of other groups(p<0.05).

Objectives : This study was undertaken to compare the effect of Foeniculi Fructus and Lonicerae Flos extract on the cerulein-induced acute pancreatitis in rats. Methods : Acute pancreatitis was induced by intraperitoneal injection of cerulein. Foeniculi Fructus extract (FE; 300 mg/kg) and Lonicerae Flos extract (LE; 300 mg/kg) were injected 2hr before induction of acute pancreatitis. Rats were sacrificed 6hr after first injection of cerulein. The severity of pancreatitis was assessed by measuring pancreatic weight/body weight ratio, neutrophil, lymphocyte, serum amylase activity, platelet activating factor (PAF) activity, tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$) activity, interleukin 6 (IL-6) activity and by histological assessments of inflammatory cell infiltration. Results : 1. The pancreatic weight/body weight ratios of FE and LE group compared with the control group were decreased significantly. 2. The neutrophil content ratio of FE and LE group compared with the control group were decreased. 3. The lymphocyte content ratio of FE and LE group compared with the control group were increased significantly. 4. The activities of serum amylase of FE and LE group compared with the control group were decreased significantly. 5. The activities of serum PAF of FE and LE group compared with the control group were decreased significantly. 6. The activities of TNF-${\alpha}$ of FE and LE group compared with the control group were decreased significantly. 7. The activities of IL-6 of FE and LE group compared with the control group were decreased significantly. 8. The pancreas injected with FE and LE showed reduction of swelling of acinar cells, inflammation and vacuolization than the control group on light microscopic observation. Conclusions : These results suggest that Foeniculi Fructus and Lonicerae Flos extract have an effect to suppress inflammation on cerulein-induced acute pancreatitis in rats. But there are no significant differences between Foeniculi Fructus extract and Lonicerae Flos extract.

In order to elucidate the correlation between the lipid peroxidation and hepatotoxicity, the formation of malondialdehyde (MDA) in liver homogenate and serum, and the transaminase activities were determined in intoxicated by ascorbic acid-Fe$\^$2+/-ADP in rat. In a model of ascorbic acid-Fe$\^$2+/-ADP hepatotoxicity, G009, which was obtained from Ganoderma lucidum IY009, exhibited anti-lipid peroxidative effect in rat liver homogenate, and that MDA values of the liver homogenate decreased from 48.1% to 74.8% in comparision to controls (p<0.01) Also, the MDA formation in serum inhibited 66.5% at 100 mg/kg of G009. Serum levels of glutamic oxaloacetic transaminase(GOT) and glutamic pyruvic transaminase(GPT) in peroxidizer-induced rats treated with G009 was decreased compared with control. Especially, The formation of lipid peroxides in serum was related to GPT levels. These results that G009 has a protective effect on ascorbic acid-Fe$\^$2+/-ADP-induced hepatic injury through an inhibition of lipid peroxidation in liver.

Objective: An experiment was conducted to determine the effects of supplementing graded concentrations of inorganic sulphur (S) without and with folic acid (FA) in maize-soybean meal diets on performance, slaughter and anti-oxidant variables, immune responses and serum protein fractions in broiler chicken. Methods: Inorganic S was supplemented at 0.05%, 0.10%, 0.15%, and 0.20% alone or in combination with FA (4 mg/kg) in basal diet (BD) containing no supplemental methionine (Met) and FA. A control group was fed with the recommended concentration of Met. Each diet was offered to 10 pens of 5 male broiler chicks (Cobb 400) and fed ad libitum from day 1 to 42. Results: The broilers fed the BD had lower body weight gain (BWG), feed efficiency (FE), higher lipid peroxidation (LP), lower activity of glutathione peroxidase (GSHPx), lower lymphocyte proliferation ratio (LPR), and reduced concentrations of total protein, albumin, and globulin in serum. Supplementation of FA and S to the BD improved the BWG (all concentrations of S) and FE (0.20% S) similar to the control group. Similarly, the combination of S and FA significantly improved the concentrations of total protein, albumin, and globulin in serum, reduced the LP and increased the activity of GSHPx and LPR. However, responses in the above parameters were related to the concentration of S in the diet. The slaughter variables and antibody titres against the Newcastle disease were not affected with the treatments. Conclusion: Based on the results, it is concluded that the combination of S (0.2%) and FA (4 mg/kg) improved the BWG and FE, similarly supplementation of these nutrients improved the concentration of protein fractions and reduced the stress (reduced LP and improved GSHPx) variables in serum and improved the cell mediated immune response (LPR) in broilers fed sub-optimal concentrations of Met in diet.

This study was undertaken to investigate the effect on the Cd accumulation in long-term Cd poisoned rats. 40 male weaning Sprague Dawley rats weighting 80-90g were divided into 4 groups (LCuLFeCd : low Cu, Fe and Cd group, ACuLFeCd : adequate Cu, low Fe and Cd group, ACuAFeCd : adequate Cu, adequate Fe and Cd group) according to Cu and Fe levels (Cu 0.5ppm, 8.5ppm : Fe 6ppm, 40ppm) for 12 weeks. There were no significant difference in water intake, feed intake, and body weight gain according to dietary Cu and Fe consumption. But the mean food intake and body weight gain of adequate Fe groups(LCuAFeCd, ACuAFeCd) were higher than those of deficient Fe groups (ACuLFeCd, LCuFeCd)in long-term Cd poisoned rats. The mean Cd levels of serum, liver, kidney, and urine in ACuAFeCd group were lower than those of Cu and /or Fe deficient groups. But the mean fecal Cd excretion of ACuAFeCd group was higher than that of Cu and/or Fe deficient groups. And the mean Cd retention amount of ACuAFeCd group was lower than those of Cu and/or Fe deficinet groups. In conclusion, these results provide an evidence that adequate Cu and Fe intakes can decrease Cd accumulation in rats. Therefore, in the point of increasing environmental Cd contamination, adequate Cu and Fe intakes must be suggested to prevent Cd accumulations.

This study was undertaken to investigate the effects of dietary low (Fe) levels on Fe metabolism of cadmium(Cd) poisoned rats. 40 male Sprague weaning Dawley rats weighing 80-90g were divided into 4 groups(LFe:low Fe, LFeCd:low Fe and Cd, AFe: adequate Fe, AFeCd: adequate Fe and Cd) according to Cd administration(0, 50ppm in drinking water) and Fe levels(Fe:6ppm, 40ppm in diet)for 12 weeks. The food intake and body weight gain of Cd group with low Fe(LFeCd) were significantly lower than those of without Cd group with adequate Fe(AFe)(p<0.01, P<0.05). But there was no significantly difference between Cd groups and without Cd groups in water intake. The blood levels of hemoglobin, hematocrit, and serum levels of Fe of LFeCd were significantly lower than those of AFe(p<0.01, p<0.05, p<0.001). The urinary and fecal excretion of Fe of LFeCd was significantly lower than that of AFe(p<0.05, p0.05). The levels of Fe of liver, spleen in LFeCd were lower than those of AFeCd(p<0.05, p<0.05). These results indicates that adequate iron supplementation to Cd pretreated rats induce protective effects on the reduction of Fe status by Cd poisoning.

Objective: Minerals are one of the important nutrients for supporting the growth of sheep grazing in the highland, northwest of China. The experiment was conducted to investigate the relationship of both macro and micro minerals in sheep grazing in the highlands of six districts located in the Qilian Mountain of China. Methods: Samples of herbage (n = 240) and soil (n = 240) were collected at random in a "W" shape across the area designated for harvesting from 24 farms, where the sheep commonly graze in October (winter) for mineral analyses. In addition, serum samples were taken via jugular vein from 20 sheep per farm from 24 farms (n = 480 samples in total) for serum minerals analyses. Mean values of macro and micro minerals were statistically compared among districts and the correlations among soil-plant-animal were statistically analyzed and correlations were regressed, as well. Results: The results revealed that there were variations for both macro and micro minerals among districts. Statistical analysis of the correlation coefficients between herbage and sheep were significantly different for most of the minerals but not for P, Cu, and Se. Many correlation regression coefficients were found significantly different among minerals of herbage, soil, and sheep serum especially those of K, Na, Fe, Mn, and Zn (between herbage and sheep serum), and Fe and Mn (between herbage and soil), Na, Fe, Mn, and Zn (between soil and sheep serum), respectively. The regression coefficient equations derived under this experiment for prediction of Ca (R² = 0.618), K (R² = 0.803), Mg (R² = 0.767), Na (R² = 0.670), Fe (R² = 0.865),Zn (R² = 0.950), Mn (R² = 0.936), and Se (R² = 0.630), resulted in significant R² values. Conclusion: It is inferred that the winter herbage minerals in all the districts were below the recommended levels for macro minerals which indicated there would be some mineral deficiencies in sheep grazing the herbage in these regions. Supplemental minerals may therefore play an important role in balancing the minerals available from the herbage in winter and would lead to increased productivity in sheep on the highland areas of China. These findings could be potentially applied to the other regions for improving the livestock productivity.

This study was undertaken to investigate the effect of dietary Fe levels on Cd accumulation in Cd poisoned rats. Forty male weaning Sprague Dawley rats weighing 80-90g were divided into 4 groups(LFe : low Fe, LFeCd : low Fe and Cd, AFe : adequate Fe, AFeCd : adequate Fe and Cd) according to Cd administration(Cd : 0 or 50ppm in drinking water) and Fe levels (Fe : 6 or 40ppm in diet) for 12 weeks. The food intake and weight gain of LFe and LFeCd were significantly lower than those of AFe and AFeCd(p<0.01, p<0.001). The water intake was not affected significantly by Cd and Fe, therefore Cd intake was no significant difference between groups. The Cd accumulation of kidney in LFeCd was significantly higher than those of AFeCd(p<0.001). But the Cd accumulations of brain, liver and spleen were not significantly different between Cd groups and without Cd groups. The serum Cd content and urinary Cd excretion of LFeCd was significantly higher than those of AFeCd(p<0.01, p<0.01). But the fecal Cd excretion of LFeCd was significantly lower than that of AFeCd(p<0.001). The Cd retention, Cd retention rate, and apparent Cd digestibility of LFeCd were significantly higher than those of AFeCd(p<0.001, p<0.001, p<0.001). It was concluded that adequate Fe supplementation have protective effects on the long term Cd poisoning in rats.
