Resettling,disconnecting or displacing? Attending to local sociality,culture and history in disaster settings

In many disaster settings, top‐down responses emphasise ‘expert‐led’ solutions that often involve relocating disaster‐affected communities. While the intention might be to move people from harm's way and facilitate recovery, failure to attend to local pre‐disaster circumstances as well as the interplay between power, resilience and vulnerability within and around affected communities often sees resettlement reconfigure as displacement or disconnection. This oversight may even usher in a new phase of dispossession and disadvantage for marginalised groups (particularly in colonial settings). This paper explores experiences in Australia, Japan and Taiwan to reflect on what issues of local sociality, local culture and local resilience need to be attended to in framing ‘better’ disaster responses.     

Degradation of ioxynil by a soil fungus, Fusarium solani

A fungus, Fusarium solani, isolated from the soil, degraded ioxynil (3,5-diiodo-4-hydroxyben-zonitrile) in pure culture into at least eight products. Five products were detected in the organic fractions extracted from a culture grown in [¹⁴C]cyano-labeled ioxynil. Three additional products were separated by ion-exchange chromatography of the acidified aqueous phase. Cultures grown in the presence of [¹⁴C]ring-labeled ioxynil produced the same products in the organic extract and four to five products in the aqueous phase. The cyano-carbon of ioxynil was released as CO₂ at a faster rate than that of ring-carbons and was released after the initial ring cleavage. Two of the metabolites were identified as 3,5-diiodo-4-hydroxybenzamide and 3,5-diiodo-4-hydroxybenzoic acid.     

Ovarian hemangioma in swine

Eighteen (3.9%) ovarian hemangiomas were diagnosed in a survey of reproductive disorders in 460 sows from two to eight years of age during a three-year study. Ovarian hemangiomas only were observed in sows aged over 30 months, and no such neoplasms were found in 42 gilts. The incidence of ovarian hemangioma was highest at five to eight years of age. Of the 18 sows with ovarian hemangioma, one was purebred and 17 were crossbred pigs; of these, twelve had farrowed 12 to 15 litters, four had farrowed six to 11 litters and two had farrowed three litters. All 18 sows with ovarian hemangioma had one or more clinical signs related to reproductive disorders including small litter size, agalactia, fertilization failure, fetal death, silent estrus, anestrus, abortion, and stillbirth. The pathological features of the neoplasms in sows were similar to those described previously in swine and in man. Spontaneous ovarian hemangioma might provide a model for investigation of the etiology and pathogenesis of ovarian hemangioma in man.     

Use of hyperimmune serum, vaccination, and certain management procedures for control of pseudorabies in swine

A program involving use of hyperimmune serum, vaccination, and certain management procedures for the control of pseudorabies was evaluated on several farms on which the disease was enzootic. Neonatal mortality and reproductive failures on farms utilizing the program were compared with death losses and reproductive failures on farms not utilizing the program. The reduction in preweaning mortality and reproductive failures between the treated and nontreated groups were 42.1% and 39.6%, respectively.     

Antibacterial effect of chloramphenicol, thiamphenicol and florfenicol against aquatic animal bacteria

The minimum inhibitory concentration (MIC) was measured to evaluate the antibacterial activities of chloramphenicol (CP), thiamphenicol (TP) and florfenicol (FFC) against the aquatic bacterial isolates from soft-shell turtles, fish and shellfish. Amoxicillin (AMPC), oxytetracycline (OTC) and oxolinic acid (OA) were included to compare with above protein synthesis inhibitors. The results showed that the order of MIC range of the isolates from soft-shell turtles for tested drugs was OA>FFC, CP>TP> AMPC, OTC. The percentage of the resistant strains indicated that OA was the lowest (7.14%) and OTC was the highest (85.07%). The order of antibacterial activity against the isolates from fish was OA>FFC>CP>AMPC>OTC>TP. The percentage of the resistant strains revealed that OA (13.64%) and OTC (80.91%) were the lowest and the highest, respectively. For the isolates from shellfish, the order of antimicrobial activity was OA>CP, FFC>AMPC, OTC, TP. TP showed the greatest percentage of the resistant strains (58.7%), but that of OA was the lowest (4.35%). The most common resistant patterns of the isolates from turtles, fish and shellfish were AMPC-OTC, CP-TP-AMPC-OTC, and FFC-CP-TP-AMPC-OTC, respectively. There were partially-complete resistance of the resistant isolates among CP, TP and FFC. The findings indicated that previous treatment might affect the choice of drug to use for aquatic bacterial diseases.     

含莫纳可林K红曲降低鸡蛋胆固醇效果的研究

48只68周龄的海兰褐蛋鸡分成三组，按0.5％和10％比例分别添加含0．4％莫纳可林K红曲于各组日粮内，饲喂22d，观测其对鸡蛋胆固醇变化的影响。结果表明，投药后5—6d，10％添加组和5％添加组蛋黄胆固醇开始下降；15—22d的胆固醇含量与1～5d相比，10％添加组和5％添加组分别下降了9．02％和5．10％，而对照组升高了5．22％。

Lymphoid neoplasia in the koala

Objective Correlation of immunophenotype with history, anatomical and morphological features of lymphoid neoplasia in the koala.
Methods Routine necropsies were performed on 51 koalas with suspected lymphoid neoplasia between 1986 and 1997 in New South Wales and Queensland. Immuno-phenotyping was by an immunoperoxidase method utilising species cross-reactive antibodies raised against human lymphocytes and an antibody raised against koala IgG. Cases were classified according to organs and tissues affected and the morphological features of neoplastic cells.
Results Twenty-six (51%) of the cases were of the T cell immunophenotype, 12 (24%) were of B cell immunopheno-type and 13 (25%) did not stain. The age and sex of koalas did not correlate with immunophenotype (P = 0.686 and P = 1.000, respectively). Thirty-two cases were leukaemic and 36 had multiple organ involvement, probably reflecting presenta tion of koalas at advanced stages of disease. Abdominal tissue involvement was most common (44 cases), followed by nodal (32), atypical (21) and cervicomediastinal (14). The T cell immunophenotype was over-represented among the leukaemic cases (P = 0.013). Generally, the T cell immunophenotype predominated except for many affected atypical tissues. Neoplastic cells were mostly of medium nuclear size with round to oval nuclei. No correlations were found for cell morphology, mitotic index and immunopheno-type.
Conclusion The prognostic value of an immunopheno-typic, anatomical and morphological basis for the classifica tion of lymphoid neoplasia in the koala currently is limited by the need to detect these neoplasms at an early age, the requirement for freshly fixed tissues and the restricted range of available cross-reacting antibodies.
