Diversity, distribution and density of estuarine phytoplankton from nine sites under four Ranges of the Sundarban Mangrove Forests (SMF), Bangladesh have been studied. The phytoplankton communities represented by 36 species which belonged to Chlorophyceae (3), Euglenophyceae (2), Bacillariophyceae (30) and Xanthophyceae (1). Occurrence of taxa and their densities were highest near the confluence of Hangsha River (R) with the river Murdat at Patcosta. Shannon-Wiener diversity index was also highest (H = 3.494) in this area. Lowest density of phytoplankton and diversity indices (H = 1.661) were found in Bal R., Bisandri Khal and Kalabogi R. Oocystis pusilla, Coscinodiscus excentricus, C. lineatus and Navicula brekkeansis occurred abundantly, while Cyclotella comta, Thalassionema nitzschioides and Lioloma delicatula were common. Coscinodiscus lineatus was distributed in all the nine sites including high and low tides indicating its high capacity to tolerate habitat fluctuations. Chaetoceros socialis was found only in Passur R. with low salinity, conductivity and total dissolved solids. The total numbers of phytoplankton individuals per liter were generally higher during low tide than those of high one. Principal Component Analysis (PCA) showed the relationship between pH and some species of phytoplankton DOI: http://dx.doi.org/10.3329/bjb.v41i1.11086 Bangladesh J. Bot. 41(1): 87-95, 2012 (June)

SummaryIntravenous administration of arachidonic acid to guinea-pigs caused a dose-related, rapid accumulation of 51Cr-labelled platelets in the thorax. Inhibitors of cyclooxygenase inhibited the platelet accumulation, induced by arachidonic acid (30 mg/kg), at doses which did not alter the thoracic blood volume (as measured by 131I-labelled human albumin). Thromboxane synthetase inhibitors had different effects on platelet accumulation depending on the dose. CGS 12970 (3 mg/kg) and N(1-carboxyheptyl) imidazole (100 mg/kg) reduced platelet accumulation. High doses of CGS 12970 and CGS 13080 caused an apparent enhancement of platelet accumulation which was associated with pooling of blood in the thorax, as measured by either 131I-labelled human albumin or 51Cr-labelled erythrocytes. This increase in thoracic blood volume was abolished if the guinea-pigs were also pretreated with diclofenac (1 mg/kg) in addition to the thromboxane synthetase inhibitor. Increases in thoracic blood volume were also obtained following infusions of PGI2 but not PGD2 or PGE2.
