On the unknown postlarval stages of the garfish, Tylosurus strongylurus (Van Hasselt) and the seapike, Sphyraena jello Cuvier

Unknown larval stages of Tylosurus strongylurus and Sphyraena jello have been traced from Vellar Estuary, Porto Novo (lat. 11 degree 29'N; long. 79 degree 46' E). Descriptions of different stages (7-17.5 mm T. strongylurus, and 18 and 22.5 mm S. jello) are given. A thorough ichthyoplankton survey for 2 years (Nov. 1977-Oct. 1979) in the estuary revealed that these larvae were very rare in the estuary and were caught on the occasion (Nov. 1978) only.

A new record of Excirolana Orientalis (Dana, 1853), a cirolanid genus and species (Isopoda, Flabellifera) from the Pakistan coast

Excirolana orienta/is (Dana, 1853) belonging to the Cirolanidae, hitherto unknown from Pakistan, is collected from the rocky intertidal region of Manora Island, Karachi coast The specimens are fully described and illustrated. A list of the known species of the genus Excirolana is also provided since the genus is also first time reported from here.

The effects of CpG-C oligodeoxynucleotides on innate immune responses in Eriocheir sinensis (H. Milne-Edwards, 1853)

CpG oligodeoxynucleotides (ODNs) can stimulate the immune system, and therefore are widely used as a therapeutic vaccination and immune adjuvant in human. In the present study, CpG-C, a combination of A- and B-class ODN, was injected into Chinese mitten crab Eriocheir sinensis at three doses (0.1, 1 and 10 mu g crab-1), and the reactive oxygen species (ROS) levels, activities of total intracellular phenoloxidase (PO) and lysozyme-like activities, the mRNA transcripts of EsproPO, EsCrustin and EsALF were assayed to evaluate its modulating effects on the immune system of crab. The ROS levels in all treated and control groups were significantly increased from 6 to 24 h, except that ROS in 0.1 mu g CpG-C-treated crabs was comparable to that of the blank at 6 h. The PO activity was significantly enhanced and EsproPO transcripts were down-regulated (P < 0.01) at 6 h after the injection of 0.1 mu g CpG-C, with no significant changes in the other dosage treatments. The lysozyme-like activities and EsCrustin transcripts in the CpG-C-treatment groups were significantly higher than those of controls. The mRNA expression of EsALF remained almost constant in all the groups during the treatment. These results collectively suggested that CpG-C could activate the immune responses of E. sinensis, and might be used as a novel immunostimulant for disease control in crabs.

Rondom de Ander in "Na die geliefde land" van Karel Schoeman

The aim of this article is to analyse the novel "Na die geliefde land" (1972) by Karel Schoeman, by interpreting the function of 'hulle' ('they') as a category of alienation/distancing. Schoeman presented a future vision of South Africa controlled by an unidentified group of 'them' and showed Afrikaners as a marginalized group, forced to live on farms. A narrow political interpretation dominated in the reception of this book, which was treated as a simulation of the development of the political situation in South Africa. The key argument of this article is that the indeterminate representation of the situation after the revolution is not a weakness of this novel, but a conscious strategy of the author. The article argues that problems concerning political revolution ('Who', 'Why', 'When') are not that relevant in a reading of the novel because "Na die geliefde land" deals mainly with an Afrikaner community’s reactions to a changed situation.
