Background: Transfer of pesticides from environment to animal products is inevitable, so the purpose of the present work was to evaluate phosalone consumption via feeding with or without sodium bentonite (SB) on performance, blood metabolites and its transition to milk of Iranian Baluchi sheep. Methods: Twenty Baluchi ewes were divided into four treatments (P1 as control, P2, P3, and P4) of five animals in which phosalone, an organophosphate pesticide, was given via diet (only for P2 and P3) at a dose of 280 mg/sheep/day for 63 consecutive days. The SB (32 g/sheep/day; for P3 and P4) was also evaluated for its ability to reduce deleterious effects of phosalone in the sheep diets. The control group (P1) did not receive any phosalone and SB during the experiment. Sampling was conducted in two periods of time including weeks 5 and 9. Results: Phosalone residues were observed in the milk samples of P2 and P3 groups during two sampling periods. During period 1, the transfer rate of phosalone from feed to milk was 0.23 and 0.02%, respectively for the contaminated diets (P2 and P3), which is relatively similar to period 2 (0.22 and 0.02%). Only 0.34 (period 1) and 0. 36% (period 2) of phosalone residue are excreted in the feces of P2 group following its daily consumption. Transfer of phosalone from feed to milk was affected (P < 0.05) by the dietary inclusion of a commercial SB, as it (SB) decreased excretion of phosalone via milk (P3). The phosalone and SB alone or together had no significant effect (P > 0.05) on the dry matter intake (DMI) and body weight (BW) gain, but feed efficiency, milk production, milk fat, dry matter (DM) and organic matter (OM) digestibility, acetylcholinesterase (AChE) inhibitory activity, hemoglobin (Hb), red blood cell (RBC), serum glutamic pyruvic transaminase (SGPT), serum glutamic oxaloacetic transaminase (SGOT), albumin and mean corpuscular hemoglobin concentration (MCHC) affected by the treatments in period 1 or 2 (P < 0.05). The Hb, RBC, and MCHC were significantly decreased (P < 0.05) by about 9.72, 20.77, and 9.71%, respectively in the group P2 as compared to those of the control group during period 1. The AChE inhibitory activity (period 1 and 2) significantly increased when phosalone administered via the diet (P < 0.05). Conclusions: Although there were no adverse effects on the performance of sheep following the intake of phosalone alone (P2 vs. P1), but other research on the long and short times to the phosalone in high and low doses with more animals is suggested. Overall, compared to the control group, addition of SB in the diet of sheep improved nutrient digestibility, animal performance, and milk health.

The study was done to investigate the effects of the extracts from the different parts of Lythrum salicaria (LS) on liver protective activities in chronically alcohol-treated rats. SD male rats except normal animals were administrated with alcohol ($30m{\ell}$ of 30%~40% ethanol/kg/day) and the extracts (300 mg/kg/day) for 10 weeks. Chronic alcohol administration decreased body weight, high density lipoprotein (HDL)-cholesterol and the reduced form-glutathione (GSH), whereas increased the ethanol content, glutamic-oxaloacetic transaminase (GOT), total cholesterol, low density lipoprotein (LDL)- cholesterol, triglyceride in blood/serum and the ratio of the oxidized form of glutathione (GSSG) and total GSH (GSSG/total GSH) in liver tissue. Groups treated with the extracts of leaf, root and stem, showed decrease in GOT, total cholesterol and GSSG/total GSH and increase in hepatic aldehyde dehydrogenase (ALDH), total GSH and serum albumin. Administration with the root extract of LS decreased blood ethanol content compared with the other part extracts. But, serum triglyceride values in rats treated with root and stem extract were higher than that of the negative control animals. Flower extract-fed group showed decrease in body weight and serum triglyceride, but increase in the ratio of GOT and glutamic-pyruvic transaminase (GPT), and GSSG/total GSH. From the results, we conclude that the extracts of root and leaf among the plant parts of LS might be useful for the amelioration of the chronic alcohol-induced liver demage of rat.

In the study, we investigated the effect of Taurine-F^TM, which is a commercially available fishery nutritional supplements complex, on anti-hepatotoxicity stressed with thioacetamide (TAA) and innate immune responses in olive flounder. To investigate the change in liver toxicity, firstly, TAA (30 ppm/100 g of fish) was intraperitoneally (i.p.) administered 12 hr after the intramuscular (i.m.) injection of Taurine-F^TM (0.02 ml/100 g of fish)(Taurine/TAA). Secondly, Taurine-F^TM was i.m. injected 24 hr after the administration of TAA (TAA/Taurine). Finally, TAA was administered simultaneously with Taurine-F^TM (TAA+Taurine). All blood samples were collected 24 hr after injection. GOT level in group Taurine/TAA appeared similar to the control, whereas group TAA/Taurine and TAA+Taurine showed significantly increased (p<0.05) levels compared to the control. In GPT level, group Taurine/TAA and TAA/Taurine showed elevated levels compared to the control, whereas no significant difference was observed between group TAA+Taurine and the control. Serum ACH₅₀ activity was significantly (p<0.05) augmented 24 hr after Taurine-F^TM injection compared to the control group, whereas no significant increase was observed 48 hr after Taurine-F^TM injection. On the other hand, serum lysozyme activity elevated in an acute stressed condition appeared significantly down-regulated 24 and 48 hr after Taurine-F^TM injection compared to the control. In conclusion, i.m. injected Taurine-F^TM augmented flounder serum complement activity and decreased a possible handling stress resulting in reducing a serum lysozyme activity and recovering hepatotoxicity. Thus, it is assumed that i.m. injection of Taurine-F^TM mixed with antibiotics or available vaccines could be utilized as an anti-hepatotoxic recipe in fish culture industry.

In order to investigate the effects of Kyegyoksan on antitumor effects after Sarcoma 180 cells transplantation into the peritoneal cavity or left groin in mice, and immune depression in mice induced by methotrexate, the extracts of its herbal medicines were orally administered for 14 or 21 days. Experimental studies were performed for measureance of $IC_{50}$ in MTT assay, mean survival days, tumor and body weights for antitumor effects, delayed type hypersensitivity, hemagglutinine titer, hemolysin titer, rosette forming cells, interleukin-2 productivity, lymphocyte transformation, natural killer cell activity and phagocytic activity for immune responses in the immune depressed ICR mice, and SGOT, SGPT, BUN and creatinine for liver and kidney protective function in SO-rats. The results were obtained as follows: 1. From the results of MTT assay, the Kyegyoksan exstracts for SUN-1 and SUN-C4 were inhibited cell viability. 2. Mean survival time in Kyegyoksan-treated group was slightly increased with no effectiveness, as compared with the control group. 3. Tumor weight in Kyegyoksan-treated group was depressed with the statistical significance, as compared with the control group(p<0.01). 4. Body weight in Kyegyoksan-treated group was incresed with the statistical significance, as compared with the control group(p<0.05). 5. Delayed type hypersensitivity in Kyegyoksan-treated group was slightly incresed with no effctiveness, as compared with the control group. 6. Hemagglutinin titer in Kyegyoksan-treated group was incresed with the statistical significance(p<0.05), but hemolysin titer was slightly incresed with no effectiveness, as compared with the control group. 7. Rosette forming cells in Kyegyoksan-treated group was incresed with the statistical significance, as compared with the control group(p<0.001). 8. Interleukin-2 productivity in Kyegyoksan-treated group was incresed with the statistical significance, as compared with the control group(p<0.001). 9. Lymphocyte transfomation in Kyegyoksan-treated group was incresed with the statistical significance, as compared with the control group(p<0.01). 10. Natural killer cell activity in Kyegyoksan-treated group at E/T ratio 100 : 1 was incresed with the statistical significance(p<0.01), but at E/T ratio 50 : 1 and 10 : 1 was slightly incresed with no effectiveness, as compared with the control group. 11. Phagocytic activity in Kyegyoksan-treated group was slightly incresed with no effectiveness, as compared with the control group. 12. The levels of serum glutamic oxalacetic transaminase, serum glutamic pyruvic transaminase, blood urea nitrogen and serum creatinine in Kyegyoksan-treated group were not effective change, as compared with the control group. According to the above results, it could be suggested that Kyegyoksan have prominent antitumor effects, enhance both cellular and humoral immunity, and have no injury to liver and kidney functions.

Two feeding trials were conducted to determine the optimum feeding frequency in growing Korean rockfish, (Sebastes schlegeli) reared at the temperatures of $15^{\circ}C$ and $19^{\circ}C$. Fish averaging $92.2{\pm}0.7$ g (mean${\pm}$standard deviation [SD]) at $15.0{\pm}0.5^{\circ}C$ and $100.2{\pm}0.4g$ ($mean{\pm}SD$) at $19.0{\pm}0.5^{\circ}C$ water temperature were randomly distributed into each of 15 indoor tanks containing 250-L sea water from a semi-recirculation system. A total of five feeding frequency groups were set up in three replicates as follows: one meal in a day at 08:00 hour, two meals a day at 08:00 and 17:00 hours, three meals a day at 08:00, 14:00, and 20:00 hours, four meals a day at 08:00, 12:00, 16:00, and 20:00 hours, and one meal every 2 days at 08:00 hour. Fish were fed at the rate of 1.2% body weight (BW)/d at $15^{\circ}C$ and 1.5% BW/d at $19^{\circ}C$. At the end of 8 wks of feeding trial weight gain and specific growth rate were significantly higher at the fish fed groups of one meal a day and two meals a day at $15^{\circ}C$ and fish fed groups of 1 meal every 2 days at $19^{\circ}C$ were significantly lower than those of all other fish fed groups. Glutamic oxaloacetic transaminase and glutamic pyruvic transaminase of fish fed group at 1 meal every 2 days was significantly higher than those of all other fish fed groups in both experiments. Weight gain, specific growth rate and condition factor were gradually decreased as the feeding frequency increased. The results indicate that growing Korean rockfish 92 and 100 g perform better at $15^{\circ}C$ than $19^{\circ}C$ water temperature. As we expected, current results have indicated that a feeding frequency of 1 meal a day is optimal for the improvement of weight gain in growing Korean rockfish grown from 92 g to 133 g at $15^{\circ}C$ and 100 g to 132 g at $19^{\circ}C$ water temperature.

This study was done to determine the effect of antioxidants added perilla oil diet on the content of cholesterol, vitamin E, and lipid peroxide in serum and tissue of rats. Four groups of experimental diets, such none added perilla oil diet, ascorbic acid added perilla oil diet, vitamin E added perilla oil diet, EDTA added perilla oil diet were fed ad libitum to the 4 weeks white male rats of Sprague-Dawley strain. The results obtained are summarized as follow: 1) The body weight gain in all experimental diet groups was higher than the control gorup and EDTA added diet group was lower than the other experimental diet group, while food intake in vitamin E added diet group was the highest and vitamin C added diet group was the lowest in the control group. 2) Total cholesterol levels in serum of all experimental diet groups were lower than that of the control group and especially the level of total cholesterol in none added diet group and vitamin C added diet group were significantly lower than that of control group. 3) HDL-cholesterol levels of all experimental diet groups were lower than that of the control group and especially none added diet group was significantly lower than that of control group. 4) The activities of glutamic oxaloacetic transaminase (GOT) in serum of all experimental diet group except EDTA added diet group were higher than that of the control group and especially none added diet group was significanly higher than that of the control group. The activites of glutamic pyruvic transaminase (GPT) in serum of all experimental diet groups except vitamin C added group were higher than that of control group. 5) Vitamin E levels in serum of none added diet group and vitamin C added diet group were lower than that of the control group and vitamin E added diet group and EDTA added diet group were higher than that of the control group. 6) Vitamin E levels in liver of all experimental diet groups were higher than that of control group and especially none added diet group and vitamin E added diet group were significantly higher than that of the control group. 7) Lipid peroxide in serum of all experimental diet group were lower than that of control group and especially EDTA added diet group. 8) Lipid peroxide in liver and spleen of all experimental diet groups were higher than that of the control group and lipid peroxide in kidney of all experimental diet groups except EDTA added diet group were higher than that of the control group. Four these results, as vitamin C, vitamin E and EDTA added diets have an effect to lipid peroxide by antioxidants, it could be suggested that perilla oil diet has required to add antioxidant because it has not sufficient vitamin E for antioxidant and intake and overtake level of perilla oil diet should be studied to go ahead.
