Effect of dimethyl - - propiothetin on growth , molting and osmoregulation of litopenaeus vannamei juveniles 蜕壳和渗透调节的影响

Potassium ions balance anions and organic acids , and are thus important in osmoregulation , the control of stomatal opening , and leaf movements ( through their effects on the turgor of pulvini ) 钾离子平衡阴离子和有机酸，因此在渗透调节、控制气孔的开闭以及叶运动（通过叶枕膨大的影响）中很重要。

Conclusions : the present results indicated that the brain areas involving in the heperosmotic regulation mainly located in mvz son and pvn . the neurons and astrocytes might be very active following hyperosmotic pressure and n - asc as a functional unit might serve to modulate osmotic pressure . there was reciprocal osmoregulation pathways between the mvz and son or pvn in the brain 结论：参与大鼠高渗性渗透压调节的中枢主要位于mvz 、 son和pvn等核团，神经元和ast以n asc的形式共同参与渗透压调节反应，体内存在mvz和son或pvn之间往返的渗透压调节通路。

Methods : hyperosmotic pressure animal model was established by administering 3 % sodium chloride as drinking water to rats or increasing osmotic pressure of the culture medium . osmoregulation positions in the brain , reciprocal projection pathways between the medullary visceral zone ( mvz ) and supraoptic nucleus ( son ) or hypothalamic paraventricular nucleus ( pvn ) , oscillation of intracellular calcium in cultured neurons and astrocytes were studied by means of anti - fos , glial fibrillary acidic protein ( gfap ) , tyrosine hydroxylase ( th ) or vasopressin ( vp ) multiple imrnunohistochemical staining , immuno - electronic microscope , wga - hrp retrogradely tracing and cell culture methods . results : ( 1 ) fos positive neurons within the mvz , parabrachial nuclei , locus ceruleus , pvn , son , subfomical organ increased markedly 方法：通过给予大鼠饮用3氯化钠或提高培养基渗透压浓度的方法复制高渗刺激模型，主要采用抗fos 、胶质原纤维酸性蛋白( gfap )和酪氨酸羟化酶( th ) (或加压素? vp )免疫组织化学多重染色、免疫电镜、 wga - hrp束路追踪结合免疫组织化学多重染色、细胞培养等实验方法，系统观察了中枢参与渗透压反射的调控部位、下丘脑视上核( son )神经元? ast超微结构的变化、延髓内脏带( mvz )和son及下丘脑室旁核( pvn )之间往返投射通路和神经元的性质及其与ast的关系、培养神经元和ast内钙波的变化。

( 1 ) wheatgrass could remove the active oxygen by heightening the activity of the enzymes and protect the plants from damage at light stress . ( 2 ) wheatgrass could keep turgor pressure by osmoregulation and flexibility of cells to maintain plants developing in drought stress , some osmregulatory substance , such as the proline and the soluble sugar , increased 2 、冰草植株在渗透胁迫条件下会增加渗透调节物质如脯氨酸、可溶性糖类以降低细胞渗透势，使其在高渗溶液中仍能够保持一定水分的吸收，植株能够维持生命活动。

Shrub drought resistance mechanism , including of the relationships and changes of drought shrub growth character , anatomical structure , membrane penetration , photosynthetic characteristics and osmoregulation substance ( soluble sugar , praline , betaine and abio - hydroninm ) , aba and lea albumen , were summarized 摘要从灌木生长性状、形态结构、细胞质膜透性、光合、渗透调节（可溶性糖、脯氨酸、甜菜碱和无机离子） 、 aba和lea蛋白变化及其与灌木抗旱性的关系方面，综述了灌木抗旱机理研究。
