摘要
为了研究食品用蜡对大白鼠肠道黏膜及其相关淋巴组织的影响,运用解剖学、组织学方法对巴西棕榈蜡、液体石蜡处理的大白鼠与对照组的肠道黏膜形态、淋巴滤泡数量和杯状细胞数量进行比较研究。解剖学结果:试验组与对照组肠道黏膜无病理变化,黏膜表面淋巴集结(PP)的形态特征和数量无明显差异;小肠内PP的形态呈结节状,主要分布于空肠和回肠的黏膜表面;大肠内PP的形态呈火山口状和结节状,主要分布于盲肠和结肠的黏膜表面。组织学结果:巴西棕榈蜡试验组与对照组对比,肠绒毛有轻微脱落,淋巴滤泡和杯状细胞的数量无显著差异(P>0.05);液体石蜡试验组与对照组对比,肠绒毛脱落严重,淋巴滤泡数量无显著差异(P>0.05),杯状细胞的数量差异显著(P<0.05),结果显示,杯状细胞数量增多。食品用蜡对大白鼠肠道黏膜有不同程度的损伤,对肠道黏膜相关淋巴组织无明显影响,巴西棕榈蜡相比与液体石蜡对大白鼠肠道黏膜损伤小,选用巴西棕榈蜡作为食品用蜡比液体石蜡对肠道的影响小。
In order to Study the effects of food wax on intestinal mucosa and its related lymphoid tissue in rats,the morphology of intestinal mucosa, the number of lymphoid follicles and the number of goblet cells in rats treated with carnauba wax and liquid paraf- fin were compared with those in the control group by means of anatomy and histology. Anatomical results showed that there were no pathological changes in intestinal mucosa, and there was no significant difference in the morphological characteristics and quantity of lymphoid aggregation (PP) on the surface of intestinal mucosa between the experimental group and the control group. The morpholo- gy of PP in the small intestine was nodular, mainly distributed on the mucous surface of the jejunum and ileum. The morphology of PP in large intestine was crater and nodular, which was mainly distributed on the mucous surface of cecum and colon. The histological results showed that the intestinal villi fell off slightly, the number of lymphoid follicles and goblet cells had no significant difference between the experimental group and the control group (P >0. 05), and the intestinal villi fell off seriously in the liquid paraffin group compared with the control group. There was no significant difference in the number of lymphatic follicles (P > 0. 05), but there was significant difference in the number of goblet cells (P < 0. 05). The results showed that the number of goblet cells in- creased. Food wax had different degrees of damage to intestinal mucosa in rats, but had no significant effect on intestinal mucosa-associated lymphoid tissue. Brazilian palm wax had less damage to intestinal mucosa than liquid paraffin wax. Using Brazilian palm wax as food wax has less effect on intestinal tract than liquid paraffin.
