ABSTRACT

BACKGROUND:

The aim of present study is to compare the effectiveness, side-effect potential of different doses of sericin pleurodesis.

METHODS:

Adult, male, 12-week-old, Wistar-albino rats (n = 52), were randomly-divided into four-groups, referred to A, B, C and D. Sericin was administrated at different doses through left thoracotomy, with 15mg sericin to Group-A, 30 mg to Group-B and 45 mg to Group-C. Group-D was assigned as control group. The rats were sacrificed 12 days later. Left-hemithorax, heart, liver and kidney were examined pathologically.

RESULTS:

No foreign body reaction in the parenchyma was observed in any of the rats, while emphysema was least common in Group-B (P < .05). Multi-layer mesothelium of both pleura was most common in Group-B, while fibrosis and fibrin organization within the visceral-pleura was more successful in all of sericin treated groups than in control group (P < .05), with neither Group-A, Group-B nor Group-C being superior to each other. In the examination of collagen fibers using Masson's trichrome, "dense collagen fibers" were found in all three sericin treated groups, and differences between Groups-A, -B, -C and the control group were significant (P < .05). The probability of observing pyknotic nucleus and balloon degeneration in liver increased with increasing sericin doses (P < .05). Glomerular degeneration in kidney and the findings of pericarditis were most common in Group-C (P < .05).

CONCLUSION:

The target should be to maximize efficacy while minimizing the likelihood of side-effects. The intrapleural administration of sericin 30 mg performs better due to multi-layer mesothelial reaction being higher and emphysema being lower in Group-B, to the fewer side-effects affecting the kidney and heart, and liver toxicity not being higher
RESUMEN

INTRODUCCIÓN:

El objetivo de este estudio es comparar la efectividad y los posibles efectos secundarios de diferentes dosis del agente pleurodésico sericina.

MÉTODOS:

Se utilizaron ratas macho albinas Wistar de 12 meses de edad (n = 52) que se dividieron aleatoriamente en 4 grupos, referidos como A, B, C y D. Se administró sericina a diferentes dosis a través de toracotomía izquierda 15 mg al grupo A, 30 mg al grupo B y 45 mg al grupo C. El grupo D se utilizó como grupo control. Las ratas se sacrificaron 12 días más tarde. Se realizó examen patológico del hemitórax izquierdo, el hígado y el riñón.

RESULTADOS:

No se observaron reacciones a cuerpo extraño en el parénquima de ninguna de las ratas. El enfisema fue menos común en el grupo B (p < 0,05). El mesotelio multicapa en ambas pleuras fue más frecuente en el grupo B, mientras que la fibrosis y la organización de la fibrina en la pleura visceral tuvieron una mayor tasa de éxito en todos los grupos tratados con sericina que en el control (p < 0,05), sin ser mayor en ninguno de los grupos. Cuando se examinaron las fibras de colágeno mediante el tricrómico de Masson, se encontraron «fibras densas de colágeno» en los 3 grupos tratados con sericina, existiendo diferencias significativas entre los grupos A, B y C (p < 0,05). La probabilidad de observar núcleos picnóticos y degeneración «en globo» en el hígado se incrementó con el aumento de las dosis de sericina (p < 0,05). La degeneración glomerular en el riñón, y los hallazgos de pericarditis fueron más frecuentes en el grupo C (p < 0,05).

CONCLUSIÓN:

El objetivo debería ser maximizar la eficacia a la vez que se minimiza la probabilidad de efectos secundarios. La administración intrapleural de 30 mg de sericina resulta más eficaz debido a una mayor reacción mesotelial multicapa y a menor incidencia de enfisema (como se observa en el grupo B), así como a un menor número de efectos adversos que afectan al riñón y al corazón sin incremento concomitante de la toxicidad hepática
