Tibial dyschondroplasia (TD) cases has not been reported in Tibetan chickens (TBCs), but it is commonly seen in commercial broilers characterized by lameness. The underlying mechanism remains unclear. Hypoxia-inducible factors (HIFs) are important regulators of cellular adaptation to hypoxic conditions. In this study, we investigated the role of HIF-1α, -2α, and -3α in hypoxia and thiram-induced TD and their effect on tibial growth plate development in Arbor Acres chickens (AACs) and TBCs.... -

A monoclonal antibody (mAb) against zearalenone (ZEN) was produced using ZEN-carboxymethoxylamine and -BSA conjugates. Antibody produced by one clone showing a very high binding ability was selected and found to have a higher affinity for ZEN compared to a commerciall ZEN antibody. We developed two direct competitive ELISA systems using the selected antibody (ZEN-coated and anti-ZEN antibody-coated ELISA). Quantitative ranges for the anti-ZEN antibody-coated ELISA and ZEN-coated ELISA were from... -

The Pogo mouse is an autosomal recessive ataxic mutant that arose spontaneously in the inbred KJR/MsKist strain derived originally from Korean wild mice. The ataxic phenotype is characterized by difficulty in maintaining posture and side to side stability, faulty coordination between limbs and trunk, and the consequent inability to walk straight. In the present study, the cerebellar concentrations of glutamate and GABA were analyzed, since glutamate is a most prevalent excitatory... -

Epilepsy is a chronic disease occurring in approximately 1.0% of the world's population. About 30% of the epileptic patients treated with availably antiepileptic drugs (AEDs) continue to have seizures and are considered therapy-resistant or refractory patients. The ultimate goal for the use of AEDs is complete cessation of seizures without side effects. Because of a narrow therapeutic index of AEDs, a complete understanding of its clinical pharmacokinetics is essential for understanding of the... -

Sun-HeeKim, Chang-SubJung 대한생리학회-대한약리학회 The Korean Journal of Physiology & Pharmacology 5 Pages
대한생리학회-대한약리학회 The Korean Journal of Physiology & Pharmacology 2010, Vol.14 No.6 10 413-417 (5 pages)
For black and gray stripes, only black leading edges stimulated an ETR in all three light illumination levels. We observed less OMR and ETR results using the sine wave pattern compared to using the square wave pattern. From these results, we deduced that the goldfish tend to prefer tracking the leading edge of the pattern. The goldfish can also detect the color of the moving pattern under photopic luminance conditions. We decided that ETR is an intriguing factor in OMR, and is suitable as a... -

Induced activation of the gamma-aminobutyric acidA (GABAA) receptor in the retina of goldfish caused the fish to rotate in the opposite direction to that of the spinning pattern during an optomotor response (OMR) measurement. Muscimol, a GABAA receptor agonist, modified OMR in a concentration- dependent manner. The GABAB receptor agonist baclofen and GABAC receptor agonist CACA did not affect OMR. The observed modifications in OMR included decreased anterograde rotation... -

Sodium retention is a hallmark of nephrotic syndrome. We investigated whether sodium retention is associated with changes of natriuretic peptide system at different stages (i.e., a sodium retaining stage and a compensatory stage) of nephrotic syndrome. At day 7 after PAN (puromycin aminonucleoside) injection, the urinary excretion of sodium was decreased, along with the development of ascites and positive sodium balance. The plasma and urinary ANP (atrial natriuretic peptide) immunoreactivities... -

Glutamate and γ-aminobutyric acid (GABA) are major excitatory and inhibitory neurotransmitters in the vertebrate retina, respectively. Using the whole-cell patch clamp technique and a rapid solution changer, glutamate and GABA receptors have been extensively investigated in carp retina. Glutamate receptors on both horizontal and amacrine cells may be an AMPA preferring subtype, which predominantly consists of flop splice variants. GABAA and GABAC receptors coexist in bipolar cells and they... -
기억 기능은 단순한 기억 기능으로만 분리되지 않고 다른 뇌기능이 실제로 작동하는데 가장 기초적 이고 중요한 역할을 한다. 그러므로 기억 기능은 거의 대부분의 뇌기능과 관계되며 피질과 피질하의 대부분의 구조와 회로가 관여되고 있다. 그러므로 기억의 뇌기전을 이해하는 것은 기억 기능뿐만 아니 라 뇌기능과 뇌의 정보처리를 전체적으로 이해하는데 아주 중요하다. 기억은 실제로 세포간의 구조적 변화를 통해 형성된다. 어떠한 대상과 사건의 기억은 별도의 사항으로 기억되는 것이 아니라 그 사건 의 구성요소와 높은...

포만중추 (satiety center)를 자극하여 음식섭취를 억제한다고 알려진 CCK-8을 흰쥐 복강에 투여하여, 흰쥐 뇌의 도파민 변화에 대한 CCK-8의 효과를 관찰하였다. 흰쥐 뇌의 부위별 도파민 함량은 HPLC-ECD방법으로 측정하였으며, 시상하부와 흑질에서의 TH-immunoreactive neuron은 면역조직화학법과 영상분석법을 시행하였다. 굶긴 쥐에서는 정상 쥐에 비하여, 도파민 함량이 전두 피질, 해마, 시상하부 및 편도체에서 각각 감소하였다. CCK-8을 투여한 쥐는 정상 쥐와 굶긴 쥐에 비하여, 도파민 함량이 시상하부에서 의미있게... -

배외측 뇌교의 전기자극은 척수 수준에서 동통의 역치를 증가시키고, 또한 말초로 부터 오는 유해성 자극에 의해 야기되는 척수후각세포의 흥분성을 억제하여 진통효과를 나타낸다. 이러한 진통효과는 noradrdnergic 원심신경을 매개로 한다고 하였지만, 이직까지 이를 직접적으로 뒷받침하는 신경화학적인 증거는 보고되지 않았다. 따라서 본 실험은 뇌교에 위치한 청반핵(Locus coeruleus)의 전기자극시, 척수 수준에서 일어나는 동통조절효과를 쥐꼬리 회피 반사(Tail Flick Reflex)를 이용해 관찰하고, 이러한 동통조절효과는 어떤... -

This study was to investigate defense mechanisms on cassava induced by salicylic acid formulation (SA) against anthracnose disease. Our results indicated that the SA could reduce anthracnose severity in cassava plants up to 33.3% under the greenhouse condition. The β-1,3-glucanase and chitinase enzyme activities were significantly increased at 24 hours after inocula- tion (HAI) and decrease at 48 HAI after Colletotrichum gloeosporioides challenge inoculation, respectively, for cassava treated... -

Rice sheath blight (ShB), caused by Rhizoctonia solani Kühn AG1-IA, is one of the destructive rice diseases worldwide. The aims of this study were to develop bio- control strategies focusing on field sanitation and foliar application with a biocontrol agent for ShB manage- ment. Streptomyces padanus PMS-702 showed a great antagonistic activity against R. solani. Fungichromin produced by S. padanus PMS-702, at 3.07 mg/l inhib- ited 50% mycelial growth, caused leakage of cytoplasm, and... -

Root-knot nematodes (RKNs) are among the most destructive plant-parasites worldwide, and RKN control has been attempted mainly using chemical nematicides. However, these chemical nematicides have negative effects on humans and the environment, thus necessitating the search for eco-friendly alternative RKN control methods. Here, we screened nematicidal lactic acid bacteria (LAB) isolated from kimchi and evaluated their efficacy as biocontrol agents against RKNs. Of 237 bacterial strains,... -

Fusarium asiaticum of the F. graminearum species complex causes head blight in small-grain cereals. The nivalenol (NIV) chemotypes of F. asiaticum is more common than the deoxynivalenol (DON) chemotypes of F. asiaticum or F. graminearum in Korea. To understand the prevalence of F. asiaticum–NIV in Korean cereals, we characterized the biological traits of 80 cereal isolates of F. asiaticum producing NIV or 3-acetyl-deoxynivalenol (3-ADON), and 54 F. graminearum with 3-ADON or... -

efficacy of downy mildew severity, particularly when applied at 24 h before inoculation or co-applied with inoculum. Fungichromin at 50 μg/ml induced phytotoxicity showing minor necrosis surrounded with light yellowish halos on cucumber leaves. The concentration that leads to 90% inhibition (IC90) of sporangial germination was estimated to be around 10 μg/ml. The results provide a strong possibility of using the S. padanus PMS-702 strain as a biocontrol agent to control other plant pathogens. -

The antimicrobial activity of acetone, hexane, dichloromethane, and methanol extracts from leaves, stems, immature green fruits, and red fruits of tomato plants was examined against six phytopathogens. The minimum inhibitory concentration (MIC) of the acetonic extracts from these four plant parts was lower than that of the other solvents. Among the acetonic extracts, tomato leaves had a lower MIC than the other tomato parts. The acetonic extract from tomato leaves was therefore selected as a...
