The purpose of this study was to clarify the relationship between myocardial mitochondrial dysfunction and the degree plus duration of restricted coronary blood flow. 135 anesthetized and open-chest dogs were divided into 3 groups according to coronary occlusion time: 10, 20, and 60 min. Regional myocardial blood flow (MBF) was determined in both ischemic(More)
The role of phospholipase (PLase) in the development of heart mitochondrial dysfunction following reperfusion was studied together with the effects of dilazep on the action of PLases and reperfusion injury. In vivo experiment: Seventy six adult mongrel dogs were divided into 3 groups; the control group (n=36), the dilazep 0.5 mg group (n=17) and the dilazep(More)
OBJECTIVE To determine the concentrations of stromal cell-derived factor-1 (SDF-1/CXCL12) and vascular endothelial growth factor (VEGF) in individual human preovulatory follicles in relation to their diameter or volume for clarifying the role of these molecules in folliculogenesis. DESIGN Prospective study. SETTING Research laboratory at Kansai Medical(More)
The results on pharmacological effects of MT-141 were as follows. MT-141 did not exert effect on central nervous system in mice and rabbits but potentiated the anesthetic effect of thiopental at doses above 800 mg/kg i.v. MT-141 slightly raised a level of blood pressure in dogs and also caused a slight increase in the blood flow and heart rate when(More)
Behavioral and electroencephalographic (EEG) effects on a new macrolide antibiotic miokamycin (MOM), 9,3"-diacetylmidecamycin, were investigated in mice, rats and rabbits after oral administration. MOM caused a decrease in the spontaneous motor activity, a slight increase in the effect of megibal seizure at a dose of 1,000 mg (Potency)/kg, and an increase(More)
