Tetsuri Kondo et al.
We obtained flow-volume (F-V) curves in anesthetized rats by applying positive pressure on the body surface. To obtain the best curve, tracheal intubation with either a 12 or 13 gauge catheter and a surface pressure greater than 56 cmH(2)O ...
Open-loop dynamic and static characteristics of the carotid sinus baroreflex in rats with chronic heart failure after myocardial infarction [0.03%]
心肌梗死后慢性心力衰竭大鼠颈动脉窦压力感受器开放环路动态和静态特性研究
Toru Kawada,Meihua Li,Atsunori Kamiya et al.
Toru Kawada et al.
We estimated open-loop dynamic characteristics of the carotid sinus baroreflex in normal control rats and chronic heart failure (CHF) rats after myocardial infarction. First, the neural arc transfer function from carotid sinus pressure to s...
Estrogens inhibit food intake in CCK-1 receptor-deficient rats [0.03%]
雌激素在胆囊收缩素-1受体基因敲除大鼠中的摄食抑制作用研究
Shuichi Okamoto,Maki Shimizu,Akiko Mizuno et al.
Shuichi Okamoto et al.
In human and many other animals, estrogens inhibit food intake and increases spontaneous activity. Previous studies hypothesized that the anorexigenic effect of estrogens is mediated by the cholecystokinin (CCK)-induced satiety effect. In t...
HCO(3) (-)-dependent transient acidification induced by ionomycin in rat submandibular acinar cells [0.03%]
离子霉素诱发的大鼠下颌下腺泡细胞瞬时酸化与HCO(3)(-)有关
Hideyo Yoshida,Chikao Shimamoto,Shigenori Ito et al.
Hideyo Yoshida et al.
Ionomycin (IM, 5 microM), which exchanges 1 Ca2+ for 1 H+, changed intracellular pH (pHi) with Ca2+ entry into rat submandibular acinar cells. IM-induced changes in pHi consisted of two components: the first is an HCO3--dependent transient ...
Late sodium current contributes to diastolic cell Ca2+ accumulation in chronic heart failure [0.03%]
迟发性钠电流对慢性心力衰竭中舒张期细胞内钙离子聚集的贡献作用
Nidas A Undrovinas,Victor A Maltsev,Luiz Belardinelli et al.
Nidas A Undrovinas et al.
We elucidate the role of late Na+ current (INaL) for diastolic intracellular Ca2+ (DCa) accumulation in chronic heart failure (HF). HF was induced in 19 dogs by multiple coronary artery microembolizations; 6 normal dogs served as control. C...
Frequency analysis of electroencephalogram recorded from a bottlenose dolphin (Tursiops truncatus) with a novel method during transportation by truck [0.03%]
一种新的频率分析方法在瓶鼻海豚(Tursiops truncatus)陆地运输过程中记录脑电波中的应用分析
Fuyuko Hashio,Shinichi Tamura,Yasunori Okada et al.
Fuyuko Hashio et al.
In order to obtain information regarding the correlation between an electroencephalogram (EEG) and the state of a dolphin, we developed a noninvasive recording method of EEG of a bottlenose dolphin (Tursiops truncatus) and an extraction met...
The absence of cardiomyopathy is accompanied by increased activities of CAT, MnSOD and GST in long-term diabetes in rats [0.03%]
长期糖尿病大鼠心肌中超氧化物歧化酶等抗氧化酶活性增强与其未发生心肌病的关系研究
Svetlana Ivanović-Matić,Mirjana Mihailović,Svetlana Dinić et al.
Svetlana Ivanović-Matić et al.
The activities of the antioxidant enzymes superoxide dismutase (SOD), catalase (CAT) and glutathione S-transferase (GST), the incidence of DNA damage, the activation of poly (ADP-ribose) polymerase-1 (PARP-1), a marker of DNA repair, and co...
Spontaneous respiratory rhythm generation in in vitro upper cervical slice preparations of neonatal mice [0.03%]
新生小鼠上颈椎切片中的自发性呼吸节律产生
Suguru Kobayashi,Yutaka Fujito,Kiyoji Matsuyama et al.
Suguru Kobayashi et al.
Isolated upper cervical slice preparations were prepared from neonatal mice to examine whether spontaneous respiratory activity could be generated in the preparations. By using brainstem-spinal cord preparations, we first recorded from the ...
Dexamethasone acutely accelerates pleural fluid absorption in mice hydrothoraces [0.03%]
甲基强的松龙急性促进小鼠胸腔积液吸收作用的研究

Sotirios Zarogiannis et al.
This study assessed the effect of corticosteroid treatment in the clearance of hydrothoraces in mice. Twenty-four C57BL/6 mice were divided into four groups and were injected intrapleurally with 500 microL sterilized PBS-BSA 1% to create is...
