Resumen
Introducción

El objetivo de nuestro trabajo es estudiar el aclaramiento bacteriano en el trasplante esplénico cervical en ratas según nuestro modelo experimental.

Material y método

Distribución aleatoria de 100 ratas isogénicas tipo Lewis en 4 grupos: grupo control con laparotomía y preservación del bazo, grupo de esplenectomía, grupo de autotrasplante esplénico y grupo de trasplante esplénico heterotópico vascularizado en la región cervical. Se realizó un estudio del aclaramiento bacteriano mediante la determinación del número de colonias/ml de sangre tras infección por neumococos en una dosis de 1 × 107.

Resultados

El grupo de trasplante esplénico presenta un efecto protector frente a la bacteriemia superior al de autotrasplante y esplenectomía; aunque inferior al de control. Estas diferencias son estadísticamente significativas (p < 0,05).

Conclusiones

Nuestro modelo experimental de trasplante esplénico cervical en ratas consigue, en el aclaramiento bacteriano, valores próximos a la normalidad y superiores a los del autotrasplante esplénico.

Introduction

The aim of this study was to analyze bacterial clearance in rats after cervical spleen transplantation using our experimental model.

Material and method

One hundred isogenic Lewis rats were randomly distributed into four groups: control group with laparotomy and spleen preservation, splenectomy group, spleen autotransplantation group, and heterotopic spleen transplant group. Bacterial clearance was assessed by determination of the number of colonies per ml of blood after pneumococcus infection (1 × 107).

Results

The spleen transplantation group presented a higher protective effect against bacteremia than the autotransplant and splenectomy groups, although this effect was lower than in controls. The differences were statistically significant (p < 0.05).

Conclusions

Our experimental model of cervical spleen transplantation in rats maintains bacterial clearance at values that are close to normal levels and are higher than those obtained with spleen autotransplantation.
