The effect of monosodium glutamate used as food additive on the fallopian tubes of adult Wistar rat was investigated.
Adult female Wistar rats (n=24) of average weight of 230g were randomly assigned into three groups A, B and C in each group (n=8). The treatment groups (A & B) were given 0.04mg/kg and 0.08mg/kg of monosodium glutamate thoroughly mixed with the growers' mash, respectively on a daily basis. The control group (C) received equal amount of feeds (Growers' mash) without monosodium glutamate added for fourteen days. The growers' mash was obtained from Edo Feeds and Flour Mill Ltd, Ewu, Edo State and the rats were given water liberally. The rats were sacrificed on day fifteen of the experiment. The fallopian tubes were carefully dissected out and quickly fixed in 10% buffered formaldehyde for routine histological procedures.
The histological findings in the treated groups showed evidence of cellular hypertrophy, degenerative and atrophic changes, and lysed red blood cells in lumen with the group that received 0.08mg/kg of monosodium glutamate more severe.
MSG may have some deleterious effects on the fallopian tubes of adult female Wistar rats at higher doses and by extension may contribute to the causes of female infertility. It is recommended that further studies aimed at corroborating these findings be carried out.
研究了用作食品添加剂的味精对成年Wistar大鼠输卵管的影响。
平均体重230g的成年雌性Wistar大鼠(n = 24)随机分为A、B、C三组,每组(n = 8)。治疗组(A和B)分别每天给予与生长育肥料充分混合的0.04mg/kg和0.08mg/kg味精。对照组(C)接受等量未添加味精的饲料(生长育肥料),持续14天。生长育肥料购自江户州埃武的江户饲料和面粉厂有限公司,大鼠可自由饮水。在实验的第15天处死大鼠。小心取出输卵管并迅速固定在10%缓冲甲醛中,进行常规组织学检查。
治疗组的组织学检查结果显示有细胞肥大、退行性和萎缩性变化的证据,且在管腔中有溶解的红细胞,接受0.08mg/kg味精的组变化更严重。
高剂量味精可能对成年雌性Wistar大鼠的输卵管有一些有害影响,进而可能导致女性不孕。建议开展进一步研究以证实这些发现。
