Summary of "Experimental animal study of docetaxel combined with carboplatin in the treatment of retinoblastoma."

The synergistic effects of docetaxel (DTX) combined with carboplatin in the treatment of retinoblastoma (RB) was explored in mouse RB xenografts compared with carboplatin alone and DTX alone groups. Retinoblastoma Y-79 cells (4.0×10/ml) were injected into the vitreous body of the right eye of mice to establish the mouse model of RB xenografts. Then the mice were randomly divided into 4 groups (n=30): DTX combined with carboplatin group (group A), carboplatin group (group B), DTX group (group C) and blank control group (group D). The changes in tumors, the survival time of mice, and the synergistic effects of DTX combined with carboplatin were observed and analyzed. The diameters and weight of the right eyeballs of the Institute for Cancer Research (ICR) mice were significantly larger and higher than those of the left eyeballs in each group, respectively (P<0.05). The diameters and weight in group A were significantly shorter and lighter than those in the other three groups, respectively (P<0.05), and there was no significant difference compared with that of normal eyeballs (P>0.05). There was no difference in diameter and weight between group B and group C (P>0.05), but the diameters and weight were shorter and lighter than those in group D, respectively (P<0.05). The survival time of ICR mice in groups A, B and C was significantly longer than that in group D (P<0.05). The survival time in group A was significantly longer than that in groups B and C (P<0.05). There was no significant difference in the survival time between the group B and group C (P>0.05). DTX, carboplatin and the combination of the two have significant inhibitory effects on RB; however, DTX combined with carboplatin has a better therapeutic effect on RB.

Medical and Biotech [MESH] Definitions

A process involving chance used in therapeutic trials or other research endeavor for allocating experimental subjects, human or animal, between treatment and control groups, or among treatment groups. It may also apply to experiments on inanimate objects.


The killing of animals for reasons of mercy, to control disease transmission or maintain the health of animal populations, or for experimental purposes (ANIMAL EXPERIMENTATION).

Physical manipulation of animals and humans to induce a behavioral or other psychological reaction. In experimental psychology, the animal is handled to induce a stress situation or to study the effects of "gentling" or "mothering".

An experimental animal model for central nervous system demyelinating disease. Inoculation with a white matter emulsion combined with FREUND'S ADJUVANT, myelin basic protein, or purified central myelin triggers a T cell-mediated immune response directed towards central myelin. The pathologic features are similar to MULTIPLE SCLEROSIS, including perivascular and periventricular foci of inflammation and demyelination. Subpial demyelination underlying meningeal infiltrations also occurs, which is also a feature of ENCEPHALOMYELITIS, ACUTE DISSEMINATED. Passive immunization with T-cells from an afflicted animal to a normal animal also induces this condition. (From Immunol Res 1998;17(1-2):217-27; Raine CS, Textbook of Neuropathology, 2nd ed, p604-5)
