ABSTRACT

Multiple short-term and long-term complications might occur after liver transplantation. In the early stage after liver transplantation, the incidence of multidrug-resistant bacteria is likely to cause different types of infection, one of which is intestinal flora imbalance. In the recent decade, a series of studies have demonstrated that intestinal flora plays an important role in maintaining intestinal homeostasis. Intestinal flora may interact with other organs via multiple patterns. Among which, gut-liver axis is one of the most critical channels for regulating microenvironment of the host. Changes in the quantity and composition of intestinal flora could lead to intestinal flora imbalance. In both local and systemic systems, extensive interaction exists between intestinal flora and immune system. In this article, the risk factors of intestinal flora imbalance after liver transplantation, influence of intestinal flora imbalance on liver transplant recipients and relevant treatment strategies were reviewed.

ABSTRACT

Studies on community structures of earthworms of rubber (Hevea brasiliensis) plantations and their adjacent mixed forests in West Tripura (India) revealed that both the studied sites harvoured 10 earthworm species. Nine species (Pontoscolex corethrurus, Kanchuria sp 1, Metaphire houlleti, Drawida papillifer papillifer, Drawida assamensis, Gordiodrilus elegans, Eutyphoeus assamensis, Eutyphoeus comillahnus and Eutyphoeus gigas) were common to both. While Octochaetona beatrix was found only in the rubber plantations, Dichogaster affinis was restricted to the mixed forest only. Earthworms were found mostly within 15 cm depth of soils having mean temperature of 27ºC, moisture of 23%, pH of 4.57, organic matter of 1.34% and water holding capacity of 36%. Mean earthworm density in rubber plantations (115 ind. m-2) was significantly higher (p = 0.003, t = 3.83) than that in the mixed forests (69 ind. m-2) due to dominance of Pontoscolex corethrurus, an exotic species. Numbers of dominant species were two (P. corethrurus and D. assamensis) in the rubber plantations and five (P. corethrurus D. assamensis, D. papillifer papillifer, M. houlleti and Kanchuria sp 1) in the mixed forests. Compared to the mixed forests, significantly low (p<0.05) Shannon diversity index (H) and species evenness and high index of dominance in the rubber plantation were evaluated.
