  • Objectives The purpose of this study was investigating effects of Jengjengamiyijin-tang (zhengzhuanjiaweierchentang) (JGYT) on lowering lipid, antioxidation and production of inflammatory mediators being used rats fed on high oxidized fat. Methods We divided fat Sprague-Dawley rats fed on high oxidized into 4 groups. Each of 8 rats was divided into a control group and experimental groups. We fed a control group of rats a basal diet and administered normal saline (100 mg/kg, 1 time/1 day) for 4 weeks. And We fed each experimental group of rats basal diet and administered an extract of JGYT extracts (100 mg/kg, 200 mg/kg, 300 mg/kg, 1 time/1 day) for 4 weeks. At the end of the experiment, the rats were sacrificed to determine their chemical composition. We measured lipid of plasma and liver, concentration of proinflammatory cytokines, antioxidative activity and plasma tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$), plasma interleukin-6 (IL-6), Apo-B, Apo-E and Leptin gene expression. Results 1. Concentration of plasma FFA, LDL-cholesterol, plasma and liver total cholesterol showed a significant decrement in JGYT groups. However, concentration of plasma HDL-cholesterol showed a significant increment in JGYT groups. 2. Concentration of plasma and liver TG, TBARS showed a significant decrement in JGYT groups. However, concentration of liver GSH-Px, SOD and CAT showed a significant increment in JGYT groups. 3. Plasma GPT activity and concentration of plasma IL-6, TNF-${\alpha}$, NO, Ceruloplasmin, ${\alpha}1$-acid glycoprotein showed a significant decrement in JGYT groups. 4. In the analysis of RT-PCR, gene expression of Apo-B and Apo-E in the JGYT groups showed a low expression than that of control group. However, the gene expression of leptin showed no difference in all the treatment groups. 5. The ratio of leptin expression per ${\beta}$-actin expression showed no significant difference among all treatment groups. However, The ratio of Apo-B and Apo-E expression per ${\beta}$-actin expression showed a significant decrement in JGYT groups. Conclusions According to this study, extract of JGYT showed a positive effect in lowering lipid, antioxidation and control of inflammatory mediators production.

  • Objective: This study was conducted to investigate the effects of normal and heat stress environments on growth performance and, selected physiological and immunological parameters, caecal microflora and meat quality in Cobb 500 and Ross 308 broilers. Methods: One-hundred-and-twenty male broiler chicks from each strain (one-day-old) were randomly assigned in groups of 10 to 24 battery cages. Ambient temperature on day (d) 1 was set at 32℃ and gradually reduced to 23℃ on d 21. From d 22 to 35, equal numbers of birds from each strain were exposed to a temperature of either 23℃ throughout (normal) or 34℃ for 6 h (heat stress). Results: From d 1 to 21, strain had no effect (p>0.05) on feed intake (FI), body weight gain (BWG), or the feed conversion ratio (FCR). Except for creatine kinase, no strain×temperature interactions were observed for all the parameters measured. Regardless of strain, heat exposure significantly (p<0.05) reduced FI and BWG (d 22 to 35 and 1 to 35), immunoglobulin Y (IgY) and IgM, while increased FCR (d 22 to 35 and 1 to 35) and serum levels of glucose and acute phase proteins (APPs). Regardless of temperature, the Ross 308 birds had significantly (p<0.05) lower IgA and higher finisher and overall BWG compared to Cobb 500. Conclusion: The present study suggests that the detrimental effects of heat stress are consistent across commercial broiler strains because there were no significant strain×temperature interactions for growth performance, serum APPs and immunoglobulin responses, meat quality, and ceacal microflora population.

  • The acute phase serum protein response is a well-known general indicator of inflammation, trauma or other pathological conditions and its relevance for the monitoring of the health status of domestic animals is being increasingly realized. The changes in serum protein composition which occur after tissue damage represent a part of the systemic response of the injured animals which is mediated by pro-inflammatory cytokines such as TNF-$\alpha$, IL-6 and IL-1. These responses play a vital role in containing the tissue damage and enhancing the processes of repair and resolution. From a clinical perspective, the assay of acute phase proteins can provide a method for detecting inflammation. In animals, the most sensitive acute phase proteins are haptoglogin, serum amyloid A and at-acid glycoprotein in response to inflammatory condition. The aim of this study was to assess the diagnostic value of the concentrations of serum amyloid A(SAA) and haptoglobin(HP) in serum of pigs infected with Aujeszky's disease virus(ADV). Fifty pigs infected with ADV and 5 normal pigs were used in this experiment. The mean serum concentration of Shh of pigs infected with ADV was 96.8 $\pm$ 7.1 $\mu\textrm{g}$/㎖(range, 36.0∼187.5 $\mu\textrm{g}$/㎖) and that of normal pigs was 42.9$\pm$3.3 $\mu\textrm{g}$/㎖(range, 17.3∼127.8 $\mu\textrm{g}$/㎖). The mean serum concentration of HP of pigs infected with ADV was 1,164.4 $\pm$ 96.9 $\mu\textrm{g}$/㎖ (range, 790.2∼l,769.2 $\mu\textrm{g}$/㎖) and that of normal pigs was 675.4 $\pm$ 56.3 $\mu\textrm{g}$/㎖ (range, 650.0-690.4 $\mu\textrm{g}$/㎖). The mean concentrations of SAA and HP in serum of pigs infected with ADV compared with those of normal pigs showed approximately a two-fold. It was concluded that the concentrations of Shh and HP in serum may proved to be diagnostic marker of Aujeszky's disease.

  • Coccidiosis control programs such as vaccines or in-feed anticoccidials are commonly practiced in the poultry industry to improve growth performance and health of commercial broiler chickens. In this study, we assessed the effects of various coccidiosis control programs (e.g., in ovo vaccination, synthetic chemicals, and antibiotic ionophores) on immune status of broiler chickens vaccinated against infectious bronchitis virus and Newcastle disease virus (ND) and raised on an Eimeria-contaminated used litter. In general, the levels of ${\alpha}$-1-acid glycoprotein, an acute phase protein, were altered by the treatments when measured at 34 days of age. Splenocyte subpopulations and serum antibody titers against ND were altered by various coccidiosis control programs. In-ovo-vaccinated chickens exhibited highest mitogenic response when their spleen cells were stimulated with concanavalin A (Con A) at 7 days of age. It is clear from this study that the type of coccidiosis control program influenced various aspects of innate and adaptive immune parameters of broiler chickens. Further studies will be necessary to delineate the underlying relationship between the type of coccidiosis control program and host immune system and to understand the role of other external environmental factors such as gut microbiota on host-pathogen interaction in various disease control programs.

  • This review summarizes gender differences in pharmacokinetics, pharmacodynamics, and adverse drug reactions. Gender differences in pharmacokinetics are categorized by four major factors: absorption/bioavailability, distribution, metabolism, and elimination. There are sex-based differences in gastric emptying time, gastric alcohol dehydrogenase activity, apparent volume of distribution, ${\alpha}1$-acid glycoprotein level, phase I (CYP) and phase II metabolizing enzymes, glomerular filtration rate, and drug transporters. This review also reports gender differences in pharmacokinetics and pharmacodynamics of cardiovascular agents, central nervous system acting agents and antiviral agents. In addition, it has been reported that females experience more adverse reactions such as coughing, tachycardia, nausea, vomiting, rash, hypersensitivity, hepatotoxicity, and metabolic disorder after taking cardiovascular, central nervous system acting and antiviral agents. Therefore, in order to provide optimal drug dosage regimens both in male and female, gender differences in pharmacokinetics, pharmacodynamics, and adverse drug reactions must be considered.

  • 황소의 정액에서 베타 굴룩유로니다아제를 부분적으로 정제하였다. 이 정제과정에는 $(NH_4)_2SO_4$ 의 분획분리법, 두개의 연속적인 DEAE-셀루로오즈 콜럼 및 등전초점화법(pH4-6) 및 세파덱스 G-200의 절여과 방법이 쓰여졌다. 등전초점화(lsoelectric focusing)법을 사용했을때 pH5.13에서 베타 굴룩유로니다아제는 한 형태의 단백질로 존재하였다. 고도로 정제된 베타 굴룩유로니다아제는 전기영동법에 의해 한개의 주된 띠와 약간의 불순물의 띠로 나타났고 특수활동도는 34Units/mg 단백질로 나타났다. 이 효소는 pH 5.2 와 $48^{\circ}C$ 에서 가장 높은 활동도를 나타냈다. 알부민이나 0.15M 소금용액에서 베타 굴룩유로니다아제는 활동도가 상승됐다. 페놀프타레인-모노-베타-굴룩 유로닉산을 기질로 사용했을때 km값은 2.9mM 이었고 Vmax값은 $0.8{\mu}$mole/min 이었다. 대두의 콘카나발린 A에 흡착하는 것으로 보아 이 효소는 당단백질임이 확인됐다. 토끼, 사람의 정자 아크롬좀 추출물 및 정액에서 이 효소는 높은 활성도를 나타냈다.
