Cork Oak Seedling Growth under Different Soil Conditions from Fertilisation, Mycorrhizal Fungi and Amino Acid Application
Regeneration process deals with some constrains related with the livestock management, pasture rotations, and
dependence of a sequence of favourable climatic years, among others, which can lead to a continuous delay in
the initiation of the regeneration process. The purpose of this study is to promote an increase of cork oak
seedling growth in order to decrease the time required for regeneration and also to contribute to avoid the effect
of post-transplant stress on cork oak. With this objective, a study was carried out on a greenhouse, where the
effect of fertilisation, mycorrhizal fungi inoculation, and amino acid supply were tested. Results showed that
cork oak seedling capability to growth, expressed as total seedling dry weight, was positively affected by
treatments, except when only fertilisation was applied. We verified that cork oak seedlings inoculated with
mycorrhizal fungi presented better results in terms of aerial structures growth. Any of the treatments was suitable
to contribute positively for tap root and total belowground dry weight accumulation. Only fine roots structures
were sensitive to treatments effects; it was verified that both inoculated and non-inoculated seedlings subjected
to fertilisation were capable to invest largely on the production of these structures (33 and 30%, respectively). To
reinforce the cork oak seedling growth, the equilibrium between fertilisers and mycorrhizal fungi inoculation
would probably be the better option to enhance the cork oak regeneration process. Thus, the balance between
shoot and root systems growth would be guaranteed, fertilisation mainly for root system and mycorrhizal fungi
inoculation for shoot growth

Effects of bromopride on the healing of left colon anastomoses of rats
Objetivo: Avaliar os efeitos da bromoprida sobre a formação de aderências e a cicatrização de anastomoses de cólon esquerdo de
ratos. Métodos: Foram incluídos 40 ratos, divididos em dois grupos contendo 20 animais, para administração de bromoprida (grupo
de estudo- E) ou solução fisiológica (grupo controle- C). Cada grupo foi dividido em subgrupos contendo 10 animais cada, para
eutanásia no terceiro (E3 e C3) ou no sétimo dia (E7 e C7) de pós-operatório. Os ratos foram submetidos à secção do cólon esquerdo
e anastomose término-terminal. No dia da relaparotomia, foi avaliada a quantidade total de aderências e removido um segmento
colônico contendo a anastomose para análise histopatológica, da força de ruptura e da concentração de hidroxiprolina. Resultados:
Não houve diferença entre os grupos em relação à evolução clínica. Dois animais do grupo de estudo apresentaram deiscência
de anastomose bloqueada. Os animais que receberam bromoprida apresentaram número de aderências intracavitárias e aderências
à anastomose semelhantes ao grupo controle. As anastomoses dos animais do grupo E3 apresentaram menor resistência de ruptura
do que as do grupo C3 (p=0,04). Este efeito não ocorreu no sétimo dia de pós-operatório (p=0,37). Não houve diferença significativa
entre os grupos em relação à histopatologia ou concentração de hidroxiprolina das anastomoses. Conclusão: O uso da bromoprida
está associado à diminuição da resistência tênsil de anastomoses do cólon esquerdo de ratos no terceiro dia de pós-operatório.Objective: To evaluate the effects of bromopride on the formation of adhesions and anastomotic healing in the left colon of rats.
Methods: We divided 40 rats into two groups of 20 animals, administration of bromopride (study group-E) or saline (control group-
C). Each group was divided into subgroups containing 10 animals each for euthanasia in the third (C3 and E3) or the seventh (E7 and
C7) postoperative days. The rats were submitted to section of the left colon and end-to-end anastomosis. On the day of reoperation,
we evaluated the total amount of adhesions and removed a colonic segment containing the anastomosis for histopathological
analysis, assessment of rupture strength and hydroxyproline concentration. Results: There was no difference between groups in
relation to clinical outcome. Two animals in the study group had blocked anastomotic leakage. The animals that received bromopride
had the number of intracavitary adhesions and adhesions to the anastomosis similar to the control group. The anastomoses from the
group E3 animals showed lower resistance to rupture the one from the C3 group (p = 0.04). This effect did not occur on the seventh
postoperative day (p = 0.37). There was no significant difference between groups in relation to histopathology and hydroxyproline
concentration in the anastomoses. Conclusion: The use of bromopride was associated with decreased tensile strength of left colon
anastomosis in rats in the third postoperative day
