ABSTRACT
Abstract

Introduction:

Submandibular glands are exposed to many effects due to diseases and therapeutic interventions. A study evaluating the effect of submandibular gland dysfunction on the parotid gland has not been presented in the literature.

Objective:

The aim of this study was to evaluate the histopathological changes in the parotid gland following submandibular gland failure.

Methods:

Three groups of seven randomly selected female New Zealand rabbits weighing 2500-3000 g were studied. Unilateral and bilateral submandibular glands were removed in Groups 1 and 2, respectively. No procedure was performed in Group III, the control group. The parotid glands were removed 30 days later. Histological parameters were evaluated and graded between 0 (none) and 3 (severe). Differences between groups were compared using the Mann-Whitney U test.

Results:

Mean mucus accumulation in acinar cells was 2.57 ± 0.53 and 1.71 ± 0.75 in Groups 1 and 2, respectively (p < 0.05). This value was 0.57 ± 0.53 in Group 3, which was significantly lower than in Groups 1 and 2 (p < 0.05). Mean dilatation of the intercalated ducts' lumen was 1.28 ± 0.48 and 1.57 ± 0.53 in Groups 1 and 2, respectively (p > 0.05). This value was 0.28 ± 0.48 in Group 3, which was significantly lower than in Groups 1 and 2 (p < 0.05). Mean mucus accumulation in the intercalated ducts' lumen was 2.00 ± 0.81 and 1.00 ± 0.57 in Groups 2 and 3, respectively (p < 0.05).

Conclusion:

The findings of this study indicate that only 1 month after submandibular gland failure, the parotid glands exhibit significant changes.
RESUMO
Resumo

Introdução:

As glândulas submandibulares estão expostas a muitos efeitos causados por doenças e intervenções terapêuticas. Estudos que avaliam o efeito da disfunção da glândula submandibular na glândula parótida ainda não foram reportados na literatura.

Objetivo:

O objetivo deste estudo foi avaliar as alterações histopatológicas na glândula parótida após insuficiência da glândula submandibular.

Método:

Três grupos de sete coelhas fêmeas da raça Nova Zelândia, selecionadas aleatoriamente, pesando entre 2.500 e 3.000 gramas foram estudadas. As glândulas submandibulares unilaterais e bilaterais foram removidas nos Grupos 1 e 2, respectivamente. Nenhum procedimento foi realizado no Grupo III, o grupo controle. As glândulas parótidas foram removidas 30 dias depois. Os parâmetros histológicos foram avaliados e classificados entre 0 (nenhum) e 3 (grave). As diferenças entre os grupos foram comparadas usando o teste U de Mann-Whitney.

Resultados:

O acúmulo médio de muco nas células acinares foi de 2,57 ± 0,53 e 1,71 ± 0,75 nos Grupos 1 e 2, respectivamente (p < 0,05). Esse valor foi de 0,57 ± 0,53 no Grupo 3, significativamente menor do que nos Grupos 1 e 2 (p < 0,05). A dilatação média do lúmen dos dutos intercalados foi de 1,28 ± 0,48 e 1,57 ± 0,53 nos Grupos 1 e 2, respectivamente (p > 0,05). Esse valor foi de 0,28 ± 0,48 no Grupo 3, significativamente menor do que nos Grupos 1 e 2 (p < 0,05). O acúmulo médio de muco no lúmen dos dutos intercalados foi 2,00 ± 0,81 e 1,00 ± 0,57 nos Grupos 2 e 3, respectivamente (p < 0,05).

Conclusão:

Os achados deste estudo indicam que apenas um mês após a insuficiência da glândula submandibular as glândulas parótidas apresentam alterações significativas.
