( B. ) nodosa sp. nov. , Ⅰ. ( B ) ellipso-ides sp. nov. , Ⅰ. ( B. ) sp.nov. ( l), Paracerithium pentagonum sp.nov., Ceri-thinella sp. , Pileolus circularis sp.nov., Trochaliella conica gen. et sp. nov. , Fibuloptyxis ngariensis sp. nov. , Laevi nerinea planohercosa sp. nov. , Adi- ozoptyxis cylindrica sp. nov., A. subcylindrica sp.nov. , Nerineopsis sp., Nerinea paradomaensis sp. nov,, N. parahicoriensis sp. nov., Tomyris quin-quelirata sp. nov., Omphalotrochus whitneyi (Meek), Euspira rect ilabrum (Conrad ) , Pseudamaura lepta Sohl, Lunatia? ampullaria ( Sowerby ) .The oldest gas-tropods in this region are represented by the Pararaphistoma assemblage of Early to Middle Ordovician in age. The species Straparollus dionysii de Montfort collected from Zanda Co. is believed to be of Early Carboniferous, as it was first described from the Namwrian of Belgium. The Early Permian Mourlonia assemblage associated with the bivalve Eurydesma represents a cold-water fauna in the Tethys and is also closely related to gastropods from the Productus limestone of ihe Salt Range. The Triassic gastropods so far identified consist of only two species from Zanda Co, : Omphalotrochus whitneyi (Meek) and Lunatia? ampullaria ( Sowerby ) .The Cretaceous of Ngari contains a gastropod fauna which is remarkably abundant and diversified. Three distinct assemblages are recognized from separate localities. ( 1 ) Itieria-Laevine rineaassemblage, which occurs in shelly limestone in Jiagang Group, is characterized by a number of new species and it seems to be restricted in geographical distribution. ( 2 ) Adiozoptyxis assemblage marked by very large cylindrical shells, which is also found in Jiagang Group, is widely distributed in the Cretaceous rocks of Europe and Asia including Northern Xizang. It may be compared to Northern Xizang forms of Aptian age. ( 3 ) Nerinea paradomaensis assemblage(inclu-ding N. paradomaensis sp. nov. and N. parahicoriensis sp. nov. ) occurs in dark thick shelly limestone, but it is not associated with any other fossils of definite age; however, N. parahicoriensis may be related to N. hicoriensis Cra-gin from the Comanche faunas of Texas, hence it is tentatively assigned to Late Aptian to Cenomanian in age. Tertiary gastropods occur more sporadically, and only two taxa have been identified: Tomyris guiguelirata sp. nov.and Pseudamaura lepta Sohl of Eocene in age.

Fluorescent Ca2+ indicators Quin2 and Indo-1 were employed to investigate the increase of free cytosolic Ca2+ concentration of T lymphocytes stimulated by Con A. It was observed that increase of [Ca2 +]i of T lymphocytes occurred within 30 seconds after Con A addition and reached maximum at 2-3 minutes, then slightly declined to a plateau, which showed that the [Ca2+]i was about 100nM higher than the resting level.

Fluorescent Ca2+ indicators Quin2 and Indo-1 were employed to investigate the increase of free cytosolic Ca2+ concentration of T lymphocytes stimulated by Con A. It was observed that increase of [Ca2 +]i of T lymphocytes occurred within 30 seconds after Con A addition and reached maximum at 2-3 minutes, then slightly declined to a plateau, which showed that the [Ca2+]i was about 100nM higher than the resting level. It was also shown that the increase in [Ca2+]i induced by Con A stimulation was due to both increased net influx of Ca2+ across the plasma membrane and the release from intracellular calcium stores. The influx is relatively large and is responsible for the sustained plateau,whereas the release of Ca2+ from intracellular calcium stores is small and transient. The increase in [Ca2+]i induced by Con A could be blocked by vera-pamil. Neither K+ channel blocker TEA nor depolarization of the membrane by K+-riched PBS could inhibit the Con A-induced increase in [Ca2+]i. These results imply that the influx of Ca2+ is membrane potential insensitive and would depend on a kind of Receptor- Operated Ca2+ Channel rather than Potential-Operated Ca2+ Channel. In addition, the Con A-induced increase in [Ca2+]i can be enlarged by cytochalasin B.

本文分别应用荧光Ca~(2+)指示剂Quin2和Indo-1研究了Con A刺激的T淋巴细胞[Ca~(2+)]i升高过程及其发生机制.结果表明Con A与T淋巴细胞作用可导致细胞[Ca~(2+)]i的迅速升高.这种增加的胞内游离Ca~(2+)不仅来自胞外Ca~(2+)的内流,也来源于胞内钙库的释放.其中Ca~(2+)内流与T细胞钙通道的开放有关.可被钙通道抑制剂戊脉胺抑制,细胞的去极化及钾通道阻断剂四乙胺均不能阻断Ca~(2+)的内流,提示Ca~(2+)内流不是通过电位操纵的钙通道实现的,也与拥通道的开闭无关.Ca~(2+)内流可能是通过Con A受体活化的受体操纵的钙通道而实现的.
