ABSTRACT
The aim of this study was to substitute costly and hazardous compound- xylene, used as clearing agent, with less costly compounds (mixture of xylene and kerosene) having less toxicity and without compromising the cellular integrity and staining characteristics of the sections. Tissues (liver and kidney) obtained from a presumable healthy adult Wistar rat, were fixed in 10 percent formol saline, separated in to five groups (A, B, C, D and E) and processed for light microscopic study adopting H & E staining procedure. During the clearing section, groups A, B, C, D and E were respectively cleared in solvent 1 (xylene only), solvent 2 (70ml xylene 30ml kerosene), solvent 3 (50ml xylene 50ml kerosene), solvent 4 (30ml xylene 70ml kerosene) and solvent 5 (kerosene only). Our result revealed that tissues in groups A, B and C were properly cleared without any morphological impairment. The staining characteristics were also observed to be very bright. Groups D and E however presented poor staining intensity with reduced cellular details. Semi-stained transparent patches were also noticed. It is inferred from the present investigation that a mixture of xylene and kerosene could be employed in the clearing of tissues only at the prescribed ratio i.e. solvent 2 and solvent 3 without posing any health risk or compromising the cellular integrity.
RESUMEN
El objetivo de este estudio fue el de sustituir el costoso y peligroso compuesto xileno, utilizado como agente de aclaramiento, por un compuesto menos costoso (mezcla de kerosene y xileno), con menor toxicidad y sin comprometer la integridad celular ni las características de tinción de las secciones. Los tejidos (hígado y riñon) fueron obtenidos a partir de una rata Wistar adulta presumiblemente sana, los que fueron fijados en solución de formalina salina al 10 por ciento, y separadas en cinco grupos (A, B, C, D y E) y tratadas para estudio con microscópico de luz, con tinción H & E. Durante el aclaramiento de las secciones histológicas, los grupos A, B, C, D y E, fueron, respectivamente, aclarados con el disolvente 1 (sólo xileno), solvente 2 (70ml de xileno 30ml Kerosene), solvente 3 (50ml de xileno 50ml Kerosene), solvente 4 (30ml xileno 70ml kerosene) y solvente 5 (sólo el kerosene). Los resultados revelaron que los tejidos de los grupos A, B y C fueron aclarados correctamente sin alteraciones morfológicas. En la tinción también se observó como característica, ser muy brillante. Los grupos D y E, sin embargo presentaron una tinción de pobre intensidad con la reducción de los detalles celulares. Zonas con manchas semitransparentes también fueron observadas. Se infiere que una mezcla de xileno y kerosene podría ser empleado en el aclaramiento de los tejidos, sólo prescrito en la proporción del solvente 2 y 3, sin suponer ningún riesgo para la salud o comprometer la integridad celular.
