Specific anti-venom used to treat scorpion envenomation is usually obtained from horses after hyperimmunization with crude scorpion venom. However, immunized animals often become ill because of the toxic effects of the immunogens used. This study was conducted to evaluate the toxic and immunogenic activities of crude and detoxified Tityus serrulatus (Ts) venom in sheep during the production of anti-scorpionic anti-venom. Sheep were categorized into three groups: G1, control, immunized with... -

Transvaginal ultrasound-guided follicle aspiration is one method of obtaining recipient oocytes for equine somatic cell nuclear transfer (SCNT). This study was conducted: (1) to evaluate the possibility of oocyte aspiration from pre-ovulatory follicles using a short disposable needle system (14-G) by comparing the oocyte recovery rate with that of a long double lumen needle (12-G); (2) to investigate the developmental competence of recovered oocytes after SCNT and embryo transfer. The recovery... -

Clostridium (C.) difficile is a common cause of nosocomial diarrhea in horses. Vancomycin and metronidazole have been used as standard treatments but are only moderately effective, which highlights the need for a novel alternative therapy. In the current study, we prepared antiserum of equine origin against both C. difficile toxins A and B as well as whole-cell bacteria. The toxin-neutralizing activities of the antibodies were evaluated in vitro and the prophylactic effects of in vivo passive... -
A simplified one-step nuclear transfer procedure alters the gene expression patterns and developmental potential of cloned porcine embryos

대한수의학회 Journal of Veterinary Science 2014, 제 15권 제 1호 8 73-80 (8 pages)
Various somatic cell nuclear transfer (SCNT) techniques for mammalian species have been developed to adjust species-specific procedures to oocyte-associated differences among species. Species-specific SCNT protocols may result in different expression levels of developmentally important genes that may affect embryonic development and pregnancy. In the present study, porcine oocytes were treated with demecolcine that facilitated enucleation with protruding genetic material. Enucleation and donor... -

The effect of NaCl plus 3% chitosan on the systolic blood pressure of spontaneously hypertensive rats (SHR) were evaluated and compared with NaCl plus KCl (NaCl, 49.36% + KCl 49.36%) and chitosan or NaCl treatment alone. In SHR, administration of NaCl plus chitosan (44 mM Na/day) for two months significantly decreased the systolic blood pressure greater than of NaCl plus KCl and NaCl alone. NaCl plus chitosan resulted, though not statistically significant, in decreased urinary Na excretion and... -

Cholesterol-lowering effect of lactic acid bacteria (LAB: Streptococcus, Lactobacillus and Bifidobacterium) is well-known. Thus, we investigated LAB isolated from human intestine on the cholesterol-lowering effect in vitro. Seven Streptococcus (61.1%), 11 Lactobacillus (71.8%) and 7 Bifidobacterium (27.9%) were isolated as acid (pH 2.5 and 3.0) and bile (0.3% oxgall) tolerant strains. Streptococcus HJS-1, Lactobacillus HJL-37 and Bifidobacterium HJB-4 were finally selected as probiotic strains... -

The cadmium concentrations in mineral mixtures used in beef cattle feed in the states of Sao Paulo and Parana, Brazil was measured. The cadmium concentration was determined by inductively coupled plasma atomic emission spectrometry. Of the 36 analyzed samples, 35 had values > 0.5 ppm (range 0.5 to 11.2 ppm), which is the maximum concentration recommended [4, 18]. These findings show the necessity for careful industrial monitoring, as some mineral mixtures contain sufficient cadmium to cause... -

Polyphenols can easily react with reactive oxygen species (ROS) resulting in powerful antioxidant activity. Pyrogallol is a polyphenol found in a variety of fruits and vegetables. Therefore, plants containing pyrogallol can be used for their antioxidant, anti-bacterial, anti-fungal, anti-allergic, and anti-inflammatory properties. However, its effectiveness as an antioxidant is still a matter of debate because pyrogallol is also a superoxide anion generator and induces superoxide anion-mediated... -

In this study we aim to extensively investigate the anti-influenza virus immune responses in human pharyngeal epithelial cell line (Hep-2) and evaluate the protective role of Toll-like receptor (TLR) ligands in seasonal influenza A H1N1 (sH1N1) infections in vitro. We first investigated the expression of the TLRs and cytokines genes in resting and sH1N1 infected Hep-2 cells. Clear expressions of TLR3, TLR9, interleukin (IL)-6, tumour necrosis factor (TNF)-α and interferon (IFN)-β were detected... -

The accumulation of Ղ-amyloid (AՂ) aggregates is a characteristic of Alzheimer's disease (AD). Furthermore, these aggregates have neurotoxic effects on cells, and thus, molecules that inhibit AՂ aggregate formation could be valuable therapeutics for AD. It is well known that aggregation of AՂ depends on its hydrophobicity, and thus, in order to increase the hydrophilicity of AՂ, we considered using citrate, an anionic surfactant with three carboxylic acid groups. We... -

The purpose of this study was to provide a basis for studying the molecular mechanism of pharmacological action of chlorhexidine digluconate. Large unilamellar vesicles (OPGTL) were prepared with total lipids extracted from cultured Porphyromonas gingivalis outer membranes (OPG). The anthroyloxy probes were located at a graded series of depths inside a membrane, depending on its substitution position (n) in the aliphatic chain. Fluorescence polarization of n-(9-anthroyloxy)stearic acid was used... -

The aim of this study was to provide a basis for studying the molecular mechanism of pharmacological action of chlorhexidine digluconate. Fluorescence polarization of n-(9-anthroyloxy)stearic acid was used to examine the effect of chlorhexidine digluconate on differential rotational mobility of different positions of the number of membrane bilayer phospholipid carbon atoms. The six membrane components differed with respect to 2, 3, 6, 9, 12, and 16-(9-anthroyloxy)stearic acid (2-AS, 3-AS, 6-AS,... -

Intracellular accumulation of bile acids in the hepatocytes during cholestasis is thought to be pathogenic in cholestatic liver diseases. The objective of this study was to determine the role of lipid peroxidation and glutathione on the bile acid-induced hepatic cell death mechanism in primary cultured rat hepatocytes. To induce hepatic cell death, we incubated primary cultured rat hepatocytes with glycochenodeoxycholic acid (GCDC; 0∼400μM) for 3 hours. In electron microscopic examination and... -

외인성 taurine이 HOCl, NH2Cl과 그밖의 산화성 물질에 의한 hyaluronic acid의 변성에 미치는 영향을 관찰하였다. HOCl, NH2Cl과 그밖의 산화성 물질에 대한 taurine의 제거 작용을 조사하였다. Taurine의 항 산화 작용을 또한 치올 화합물의 작용과 비교 관찰하였다. Hyaluronic acid의 점성도는 HOCl과 NH2Cl에 의하여 뚜렷하게 용량에 따라 감소하였다. Hyaluronic acid에 대한 HOCl의 변성 효과는 NH2Cl에 의한 것보다 현저하였다. Taurine은 HOCl과 NH2Cl에 의한 hyaluronic acid의 변성을 효과적으로 용량에 따라 억제하였다.... -

Hydroxyl raical(OH⋅)을 생성하는 것으로 알려진 iron-catalyzed Haber-Weiss rocation에서 superoxide anion (O2-⋅)은 주로 Fe+++을 Fe++로 환원시키는 데에 작용하는 것으로 추정하고 있다. 이러한 OH⋅ 의 역할은 다른 환원제들에 의하여 대체가 가능할 것으로 추측되며 생물계의 환원제의 하나로써 ascorbate가 관심의 대상이 되고 있다. 이에 따라 본 연구에서는 Fe++와 H2O2 존재하에서 OH⋅ 을 생성하는 ascorbate 의 역할을 hyaluronic acid의 변성과 methional로 부터 ethylene 생성에 대한 효과로써... -

흰쥐 뇌 미토콘드리아에 의한 O2-⋅ 의 생성과 이 radical의 유해작용 및 그 작용기전을 알아보기 위하여 본실험을 수행하였다. Succinate와 antimycin존재하에서 미토콘드리아는 O2-⋅을 생성하였으며 이는 SOD-inhibitable NBT환원으로 확인되었다. 동일 조건에서 H2O2는 일차생성물인 O2-⋅의 dismutation으로 생성됨을 알수 있었다. 상기조건에서 미토콘드리아의 막지질이 파괴되었고 반응액에 첨가된 isocitrate dehydrogenase와 적혈구에 각각 불활성화와 용혈이 초래되었다. 이같은 작용은 Fe++이 있을때만 관찰...
