Effects of oral administration with fermented product from sewage in land-based seawater fish farm on haematological disturbance in the olive flounder, Paralichthys olivaceus was investigated. After 4 weeks of conditioning with a basal diet, fish were divided into 4 groups and provided experimental diet (0.1, 0.5, 1.0 and 2.0%) supplement of fermented sewage for 80 days. Proximal analysis was performed for the product of sewage which was fermented by lactic acid and yeast. RBC count, hemoglobin concentration and hematocrit value were increased according to the treated periods, however, no statistical difference was observed between control and treatment groups. There were no significant difference in serum organic, inorganic compounds and enzyme activities between control and treatment groups. This study hypothesized that the supplement of fermented product from sewage in land-based seawater fish farm might be an additive supplement for source of fish diet in view of haematological examination. Recycling of the sewage may be an economic artificial sources of diet for fish aquaculture practices.
"The Golden Mirror of Medicine(醫宗金鑑)" was compiled by the medical officers of the Qing government, headed by Wu-Qian(吳謙)."The Elimination &Supplement about the Famous Prescription Comments(刪補名醫方論)", a collection of notes written by famous scholars, is one part of "The Golden Mirror of Medicine(醫宗金鑑)" . Through the translation and comparative study of invigorative prescription(補氣方劑) in "The Elimination & Supplement about the Famous Prescription Comments(刪補名醫方論)" of "The Golden Mirror of Medicine(醫宗金鑑)" with "The Famous Prescription Comments on Ancient and Modem Times(古今名醫方論)" , we confirmed that many sentences of "The Famous Prescription Comments on Ancient and Modern Times(古今名醫方論)" were quoted, but that most of the text was not quoted as the same: it was revised and supplemented. In organization, invigoration prescriptions are placed at the head of the chapter, indicating their importance. In classification, prescriptions for reinforcing middle-jiao(中焦) and replenishing qi(補中益氣湯類 方劑) were usually included in the invigoration prescriptions(補氣方劑), which is explained in chapter II, thereby clearly distinguishing between treatments of deficiency of qi(氣虛) and combining it with the sinking of qi of middle-jiao(中氣下陷).
Purified rat liver aryl sulfotransferase IV (AST IV) was found to be inhibited in vitro by zinc, copper, cadmium and terbium. Among these four elements, zinc, copper and cadmium were all strongly inhibitory to the AST IV activity at very low concentrations (2.5 $\mu$M to 0.025 $\mu$M). In rat liver cytosol, zinc, copper and cadmium at 25 $\mu$M to 0.025 $\mu$M also decreased the AST IV activity to $50\%$ of the controls. In order to assess the possible effects of these metals on the AST IV activity recovery pattern in vivo, studies on the relationship between these minerals and dietary 2-acetylaminofluorene were conducted. Total of forty rats were fed one of five diets for 6 weeks: diet 1, Control diet plus 2-acetlyaminofluorene ($0.05\%$); diet 2, zinc-deficient diet plus 2-acetlyaminofluorene; diet 3, zinc-supplement diet plus 2-acetylaminofluorene; diet 4, copper-supplement diet plus 2-acetylaminofluorene; diet 5, cadmium-supplement diet plus 2-acetylaminofluorene. Half of the rats from each diet were changed to individual diet after 3 weeks of 2-acetylaminofluorene feeding. Placement of rats on the control diet following one cycle of 2-acetylaminofluorene feeding of 3 weeks without 2-acetylaminofluorene resulted in nearly full recovery of AST IV activity within 3 or 4 weeks. However, the rats fed diets that supplemented with zinc, copper or cadmium without 2-acetylaminofluorene showed a new pattern of lowered AST IV activity as early as the first cycle. Also, lowering in cytosolic AST IV contents was appeared in the livers from the rats, following one cycle of 2-acetylaminofluorene feeding of 3 weeks, fed one of the diets that supplemented with copper, cadmium or zinc without 2-acetylaminofluorene for ensuing 3 weeks.

The current study examined the effect of quercetin supplements on the lipid-lowering and antioxidant metabolism in ethanol-fed rats. The control $group(E_8)$ received ethanol only diet for 8 wks, whereas the other group$(E_8Q_4)$ received a diet including quercetin supplementation(0.05% wt/wt) for 4 wks while on the ethanol diet for 8wks. The hepatic alcohol dehydrogenase activity was significantly higher in the $E_8Q_4$ group than in the $E_8$ group. Supplementation with quercetin significantly elevated the HDL- cholesterol concentration, the HDL-C/total-C ratio, and lowered the atherogenic index(AI) compared to the $E_8$ group. The hepatic triglyceride and cholesterol contents were significantly lowered by the quercetin supplement compared to those of the control group. The hepatic HMG-CoA reductase and ACAT activities of the $E_8Q_4$ group were significantly lower than those of the $E_8$ group. The overall potential for antioxidant defense was significantly enhanced by the quercetin supplement, as indicated by a decrease in plasma and hepatic TBARS levels. The hepatic GSH-Px and G6PD activities were significantly higher in the $E_8Q_4$ group compared to the $E_8$ group. The current results suggest that dietary quercetin leads to the inhibition of HMG-CoA reductase and ACAT, which in turn lowers cholesterol levels and normalizes antioxidant enzyme activities.

The objective of this study is to investigate the effect of dietary glucose oxidase (GOx) supplementation on the reproductive performance, litter performance, total tract digestibility, and blood profile of lactating sows fed corn- wheat-based diet. A total of twenty multiparous sows (Landrace × Yorkshire) were allocated into one of four treatments with five replicates per treatment. The dietary treatments were as follows: CON (Basal diet), GO1 (basal diet + 200 U GOx/kg), GO2 (basal diet + 300 U GOx/kg), GO3 (basal diet + 400 U Gox/kg). Dietary GOx supplementation did not affect lactating sow's reproduction performance as well as body weight, backfat thickness, and body condition score during pre and post farrowing, and at weaning (p > 0.05). However, after farrowing to weaning period lactating sow's fed GOx supplement has linearly (p = 0.0196) decreased the bodyweight loss. While, there were no effects (p > 0.05) observed on sows backfat thickness loss, average daily feed intake, and estrus interval among treatment groups. Dietary supplementation of GOx has linearly improved the body weight gain (p = 0.049) and average daily gain (p = 0.040) of suckling piglets. The total tract digestibility of dry matter and nitrogen was linearly increased with the graded level of GOx supplement. Also, a linear effect was observed on the glucose and superoxide dismutase of blood profile with the dietary inclusion of GOx. In summary, our finding indicates that the dietary inclusion of GOx supplement with corn- wheat-based diet had a beneficial effect on the nutrient digestibility and blood profile of lactating sows and improved the growth performance of suckling piglets.

Thermal stress is a tremendous health predicament encountered by poultry farmers with adverse effects on the performance, product stature, health condition, survival, and overall welfare of poultry birds, and so requires urgent dietary user-friendly strategy to curb. This study was conducted with 200-day old broilers for the purpose of investigating the potential of phytogenics in refining the negative effects of heat stress on broiler chicken. Moringa, Phyllanthus and mistletoe leaves were processed as phytogenic supplements and incorporated into standard ration for broilers as treatments B1 (control), B2, B3 and B4 diet during the peak of thermal discomfort in humid tropics. Growth and carcass indices were monitored in a 49-day trial and blood samples were harvested at the end of the ordeal period to assess haematology, serum biochemical and oxidative stress markers with the use of standard procedures. The results obtained showed that the prevailing environmental condition in the study site indicated that the birds were exposed to heat stress. Birds fed on moringa and mistletoe supplements had higher performance index than birds without supplementation during heat stress condition, while birds fed on mistletoe supplement had the highest survival rate across the treatments. The liveweight, slaughter weight, dressed weight and eviscerated weight of heat stressed birds fed on moringa, phyllanthus and mistletoe supplements were significantly higher than birds on control treatment. Heterophyl/lymphocyte ratio of heat stressed birds without supplement were higher than birds on phytogenic supplements, with least values recorded in phyllanthus and mistletoe fed birds. Birds on phytogenic supplement tend to have lower cholesterol profile, lipid peroxidation and better antioxidant profile than birds on control treatment during heat stress conditions. Mistletoe supplementation in broiler ration enhances the survival rate, as well as promotes growth indices better among the phytogenic supplements. However, phytogenic supplements did ameliorate the negative effects of thermal discomfort on performance, physiological and oxidative stress in heat-stressed broiler chicken.
[Purpose] This study aimed to investigate the effects of branched-chain amino acid (BCAA) supplement on delayed onset muscle soreness (DOMS) by analyzing the maximum muscle strength and indicators of muscle damage. [Methods] Twelve men with majors in physical education were assigned to the BCAA group and placebo group in a double-blinded design, and repeated measurements were conducted. DOMS was induced with an isokinetic exercise. Following BCAA administration, the changes in the knee extension peak torque, flexion peak torque, aspartate aminotransferase (AST), creatine kinase (CK), and lactate dehydrogenase (LDH) concentrations were analyzed. The maximum knee muscle strength was measured at the baseline (pre-D0) following BCAA administration for 5 days before exercise (-D5, -4D, -3D, -2D, -1D). In contrast, the post-treatment measurements (D3) were recorded after BCAA administration for 3 days (post-D0, D1, D2). Blood samples were obtained before (pre-D0), immediately after (post-D0), 24 h (D1), 48 h (D2), and 72 h (D3) after the exercise to analyze the indicators of muscle strength. BCAA was administered twice daily for 8 days (5 days and 3 days before inducing DOMS and during the experimental period, respectively). [Results] There was no difference in the flexion peak torque between the groups. However, the BCAA group showed a significantly higher extension peak torque at D3 (second isokinetic exercise), compared to the placebo group (p<.05). There was no difference in AST changes between the groups. Nonetheless, the CK and LDH were significantly reduced in the BCAA group, compared to the placebo group. There was no correlation between the extension peak torque and flexion peak torque. However, the CK and LDH increased proportionately in DOMS. Moreover, their concentrations significantly increased with a decreasing peak torque (p<.01). [Conclusion] An exercise-induced DOMS results in a decrease in the peak torque and a proportional increase in the CK and LDH concentrations. Moreover, the administration of BCAA inhibits the reduction of the extension peak torque and elevation of CK and LDH concentrations. Therefore, BCAA might be administered as a supplement to maintain the muscle strength and prevent muscle damage during vigorous exercises that may induce DOMS in sports settings.

[Purpose] The composition of protein supplements, the consumption timing immediately before and after resistance exercise training (RET), and the quantity of protein supplementation may be important factors for the im-provement of muscle mass and function. Although these factors should be considered comprehensively for effective improvement of muscular function in protein supplementation, relatively few studies have focused on this area. Therefore, this study was designed to investigate whether a protein blend supplement before and after resistance exercise for 12 weeks would be effective in increasing muscular function. [Methods] In total, 18 participants were randomly assigned to a placebo (PLA) or protein blend supplement (PRO) group. All subjects followed the same training routine 3 times per week for 12 weeks, taking placebo or protein supplements immediately before and after each exercise session. The protein supplement consisted of 40 g of blend protein, including hydrolyzed whey protein. The RET consisted of lower body (barbell squat, dead lift, seated leg extension, and lying leg curl) and upper body (bench press, barbell rowing, preacher bench biceps curl, and dumbbell shoulder press) exercises. A repetition was defined as three sets of 10-12 times with 80% of one repetition maximum (1RM). [Results] Although the PRO group had a lower protein intake in terms of total food intake than the PLA group, the mean changes in muscle circumference, strength, and exercise volume increased, especially at week 12, compared to the PLA group. [Conclusion] These results suggest that the composition and timing of protein intake are more important than the total amount.

Purpose : This study aimed to introduce a 12-week muscular endurance exercise program and β-glucan consumption to obese elderly people with sarcopenia. We evaluated the program's impact on appendicular skeletal muscle strength and function, muscle function-related physical strength, blood lipids, and IGF-1. The results will serve as foundational data for preventing and improving sarcopenia. Methods : Forty elderly people aged 65 or older were recruited and underwent dual-energy X-ray absorptiometry. Based on criteria related to appendicular skeletal muscle mass (ASM/Height2: less than 5.4 kg/m2) and body fat percentage (at least 30% for women and 25% for men), we selected 24 obese elderly people with sarcopenia and excluded 56 who did not meet the criteria. Variables related to sarcopenia, blood lipids, IGF-1, and muscle function were measured before the 12-week muscular endurance exercise program. Results : In sarcopenic obese elderly participants, the 12-week muscular endurance exercise program significantly increased bone density and muscle mass while decreasing fat mass and percentage (p<.05). This program also improved grip strength, static balance, and SPPB in sarcopenic obese older adults. Furthermore, their 6-minute walk distance significantly increased (p<.05). Conclusion : Muscular endurance exercises combined with supplement intake can increase appendicular skeletal muscle and improve muscle strength and function, thereby improving the daily physical performance of the elderly.
