关于中国古代文学史编写的几点思考

我国文学史的编写存在不少问题：一是在文学理念、缟写模式和文体分类上受西方影响太大，而顾度中国文学的实际不够；二是客观叙述不够，议论、阐释、评析太多，未尽可能地还原中国文学的历史面貌；三是在元、明、清文学的璃排上反映出明显的重小说、戏曲，轻诗、文、词、赋的倾向，背离了元、明、清文学仍以诗文为主体的基本事实。

Study of marine microvibrios of Roscoff (Microvibrio marinus roscoffensis)]

Marine microvibrios, predators of E. coli, have been detected worldwide, from equatorial waters to the polar regions. The morphology and behavior of two microvibrios have been studied. Their multiplication and aggressiveness in regard to their bacterial prevy are not impeded by dialysis membranes and manifest themselves, away from all direct contact between the predator and its prey.     

Interaction of cortisol and epinephrine in the regulation of leucine kinetics in man

To assess the interaction of the two major stress hormones epinephrine and cortisol in the regulation of leucine kinetics in man, epinephrine (50 ng/kg/min) was infused either alone or in combination with cortisol (2 micrograms/kg/min) into two groups of 6 postabsorptive normal male subjects during 180 min. Plasma leucine concentrations decreased by 28% (p less than 0.05) from baseline during epinephrine treatment (plasma levels 515 pg/ml); this was due to a decrease of leucine appearance (determined by 1-13C-leucine infusions) by 23% (p less than 0.025); leucine oxidation decreased by 29% (p less than 0.05). However, when plasma cortisol concentrations were elevated to supraphysiological levels (16.3 mumol/l) during epinephrine administration, the decreases of leucine plasma concentrations, appearance and oxidation were abolished. Plasma glucose and FFA concentrations were similarly elevated during both kinds of treatment. Since leucine appearance represents a measurement of total body protein breakdown and leucine disappearance into non-oxidative pathways reflects protein synthesis, the data indicate that plasma epinephrine concentrations during severe stress exert a protein anabolic effect in man which may counteract catabolic properties of elevated plasma cortisol.
