为研究珠江口东南近海海区污损生物状况,于1.86年5月至1.87年6月,在香港东南约1.4和1.0km,水深为95和1.3m处布设了两个生物浮标站,并对距香港约1.2km,水深为1.5m处的Marex水文气象浮标上的污损生物群落进行调查.此次调查共采集和鉴定出污损生物78种,其中在浸海只有3个月的试板上,主要有柄蔓足类、水螅和藻类,优势种是细板条茗荷、茗荷和直杯螅.至于浸海时间达6～1.个月的浮标(包括沉标)及锚链系统,其上还有相当数量的多种双壳类软体动物、无柄蔓足类和苔藓动物等硬性污损生物附着.在种类垂直分布方面,污损生物群落组成随深度发生明显变化.

We consider a modified Markov branching process incorporating with both state-independent immigration and instantaneous *** existence criterion of the process is firstly *** prove that if the sum of the resurrection rates is finite,then there does not exist any *** existence criterion is then established when the sum of the resurrection rates is *** equivalent criteria,possessing the advantage of being easily checked,are obtained for the latter *** uniqueness criterion for such process is also *** prove that although there exist infinitely many of them,there always exists a unique honest process for a given *** unique honest process is then *** ergodicity property of this honest process is analysed in *** prove that this honest process is always ergodic and the explicit expression for the equilibrium distribution is established.

Objective To investigate the effect of XBXT-2 on the activity of hypothalamic-pituitary-adrenal (HPA) axis in chronic mild stress (CMS) model of *** Using ELISA to test the serum corticos- terone,adrenocorticotropic hormone (ACTH) and corticotropin-releasing hormone (CRH) level in CMS rats;Using western blot to determine hippocampal glucocorticoids receptors (GR) expression in CMS rats. Results Co-administration of XBXT-2 (25,50 mg·kg,p.o.,28 days,the effective doses for behavioral re- sponses) significantly decreased the serum corticosterone and ACTH level in CMS rats,while the CRH level was not markedly affected by chronic stress or ***,XBXT-2 significantly increased the GR ex- pression in the hippocampus of CMS *** same effects were observed in the positive control drug imipramine (1. mg·kg,p.o.).Conclusions The decrease of serum corticosterone and ACTH level,as well as the increase of hippocampal GR expression may be the mechanisms underlying the antidepressant action of XBXT-2,which may associate with HPA axis.
