One month later. Serum GH, THT3, THT4 and insulin were determined by using radio-immunity assay. The results demonstrated that both serum GH and insulin raised remarkably in experimental groups. THT4 raised only in peritioneal injection group. Besides these, the four different serum hormones showed no obvious change when the dose of samarium chloride decreased to 0.025 mg/kg with caudal vein injection.展开更多

The new evidence indicates that NPY and the receptor of NPY exist in the field CA3 of the rat hippocampus, but cardiovascular effect of NPY on CA3 of hippocampus is still unknown. We have studied the cardiovascular effect on CA3 in the anaesthetized Wistar rats injected with NPY.Among 6 rats, the basal levels of mean arterial pressure (MAP) and heart rate (HR)展开更多

Its effects on preventing and curing viral diseases have aroused the interest of many clinicians. and its prominent analgesic effect after local injection of interferon around the tumor has been reported. Whether the interferon would create the activity of analgesia is a problem worthy of studying. In order to know its function and reasonable use, we have investigated the analgesic action on the injection of interferon into brain.展开更多
