effects of monosodium glutamate on the histology of fallopian tube in female rats

ABSTRACT

To investigate the effects of orally administered monosodium glutamate [MSG] on the fallopian tube histology in adult female Wistar rat model. Experimental/Analytical study. Animal House, Isra University Hyderabad from May to November 2013. Forty adult male Wistar rats were divided into three groups; Group A. controls received 0.9% isotonic saline, Group B. received MSG orally [1.5 mg/kg], and Group C. received MSG orally [3 mg/kg]. The animals were sacrificed after six weeks. Fallopian tubes were fixed in 4% formaldehyde, and were embedded in paraffin. Tissue sections of 5micro thicknesses were subjected to haematoxylin and eosin staining and were assessed by light microscopy. The fallopian tubes [FT] of the control group A showed normal histological features. The fallopian tubes of the treated groups showed some cellular hypertrophy of the columnar epithelium, distortion of the basement membrane separating the endosalpinx from the myosalpinx. There were degenerative and atrophic changes observed in some parts; these were more pronounced in those that received 3 mg/kg body weight of MSG. There were marked vacuolations and lysed red blood cells, [3 mg/kg body weight treated rats] appearing in the stroma cells. The monosodium glutamate may have deleterious effects on the fallopian tube histology in adult female Wistar rats particularly in high dose. Therefore caution must be taken for its frequent use in female because of possibility of female infertility
