OBJECTIVES To determine the effect of acetylcholine (ACh), pilocarpine, and atropine on pain evoked responses of pain excited neurons (PEN) and pain inhibited neurons (PIN) in hippocampal CA3 region of morphine addicted rats. MATERIALS AND METHODS Female Wistar rats, weighing between 230-260 g were used in this study. Morphine addicted rats were generated(More)
AIM To study the influences of cyproheptadine (Cyp) on the endocrine functions of pituitary-thyroid axis and pancreatic beta cells in rats. METHODS The effects of Cyp on functions of pituitary-thyroid axis and pancreatic beta cells were observed by radioimmunoassay, biochemical analysis, and electron microscope. RESULTS Cyp 2.3 mg.kg-1 ig for 10 d(More)
AIM To study the effects of MK-447 on aggregation release reaction and intracellular calcium mobilization by thrombin. METHODS Aggregation and release reaction were assessed by light transmission and ATP content in rabbit citrate platelet-rich plasma (PRP), and cytosolic-free calcium was measured by fluorescence and imaging. RESULTS MK-447(More)
OBJECTIVE To study the feasibility of the formation of allogeneic tissue-engineered cartilage of certain shape in immunocompetent animal using the injectable biomaterial. METHODS Fresh newborn rabbits' articular cartilages were obtained under sterile condition (< 6 hours after death) and incubated in the sterile 0.3% type II collagenase solution. After(More)
OBJECTIVE To investigate the effect of free cartilage fragment in repair of cricoid cartilage defect. METHOD One-third of cricoid cartilage was cut and repaired with free thyroid cartilage fragment and pedicled cartilage in rabbits. The pathological changes of the cartilages were observed. RESULT 1. The free thyroid cartilage fragments were absorbed in(More)
Fetal hearts taken from the 17 day pregnant mice were cultured in minimum essential medium (MEM) + 0.5 ug ml of Na2SeO, and in MEM alone with oxygen for 24 h, and then the hearts in groups were exposed to 15, 20, 30, 40 min, 1 h, 3h and long term of anoxia respectively. The results showed that the survival and beating of the cultured fetal mouse hearts with(More)
