Concentração de nitrito endometrial e a ocorrência de patologias uterinas em vacas / Endometrial nitrite concentration and the occurrence of uterine pathologies of cows

RESUMO

Relacionou-se a concentração de nitrito com a ocorrência de enfermidades uterinas. Lavado intrauterino de 1ml de PBS foi realizado em 25 peças uterinas de vacas vazias para mensuração da concentração de nitrito pela reação de Griess. Elevada concentração de nitrito exibiu relação significativa com distrofia angiomatosa (157,57±108,80mM), endometrite (102,96±87,58mM) e fibrose periglandular (99,15±89,75mM); e não significativa com e hiperplasida endometrial cística (94,07±18,89mM) e adenomiose (77,40±81,25mM). Contudo, elevada concentração de nitrito mostrou relação significativa com adenomiose acentuada profunda pelo teste t. Os resultados indicam que a síntese de óxido nítrico está elevada nessas enfermidades.

ABSTRACT

The occurrence of uterine pathologies was evaluated considering uterine nitrite concentration. The uterus of 25 non pregnant cows was washed with 1ml of PBS to measure the nitrite concentration using the Griess reaction . There was significant relationship between high nitrite concentration with angiomatosis dystrophy (157,57 ±108,80mM), endometritis (102,96±87,58mM) and periglandular fibrosis (99,15±89,75mM). No relation was found between nitrite concentration and cystic endometrial hyperplasia (94,07±18,89mM) and adenomyosis (77,40±81,25mM). However, high nitrite concentration showed a significant relationship with deep accentuate adenomyosis by t test. The data suggest that nitric oxide synthesis is elevated in these illnesses.
