Abstract

The aim of the study was to investigate the influences of sodium fluoride on the body weight, lipid metabolism functional improvement, blood glucose level, protein component in the sera of rats which fed experimental diets for 5 weeks. Body weight gain of rats was higher in the NF25 group, NF30 group and NF50 group showed a significant difference from the basal diet group (BD group). The changes of the liver and the heart of each argan weights were observed compared to the BD group tends to appear lower in the oral NaF groups (p<0.05). Organ weight of each group of the others showed no significant difference (p<0.05). Serum concentrations of total cholesterol, low-density lipoprotein (LDL)-cholesterol, free cholesterol, triglyceride (TG), phospholipid (PL) and blood glucose were lower in BD group than basal diet plus sodium fluoride groups. Conversely depending on the concentration of sodium fluoride for the high-density lipoprotein (HDL)-cholesterol level, it showed lower results. Serum total protein was observed low showed a significant difference in the NF50 group, there was no significant difference in the other groups (p<0.05). globulin and albumin concentration levels also showed the lowest results in the NF50 group.

NaF를 용량별로 Sprague Dawley계 수컷 흰쥐에 경구 투여했을 때, 체중 및 장기 중량, 혈청 지질성분, 혈당 및 단백질 함량과 기본식이를 급여한 대조군인 BD군을 비롯하여 기본식이에 농도별 NaF를 경구 투여한 군들로 나누어 5주간 실험 사육한 결과, 흰쥐의 체중 증가량은 NF25군, NF30군 및 NF50군에서 대조군보다 유의적인 차이를 보이며 높게 나타났다(p<0.05). 각 장기무게에서의 변화 중 간장과 심장에서는 대조군에 비해 NaF 경구 투여 군에서 낮게 나타나는 경향이 관찰 되었으며(p<0.05), 폐, 뇌, 신장, 비장 및 고환에서의 각 군의 장기무게는 유의적인 차이가 없었다(p<0.05). 혈청 중 총 콜레스테롤, LDL 콜레스테롤, 유리 콜레스테롤, 중성지방, 인지질, 혈당 농도는 대조군보다 NaF 경구 투여한 군에서 NaF 농도가 높아짐에 따라 증가하였고, HDL 콜레스테롤 농도는 NaF 농도에 따라 점차 감소하는 것으로 관찰되었다. 혈청 중 총 단백질은 NF50군에서 유의적인 차이를 보이며 낮게 나타났으나 나머지 군에서 유의적 차이가 없는 것으로 나타났으며(p<0.05), 알부민 농도와 글로불린 농도 또한 NF50군에서 가장 낮은 결과치로 나타났다. 반면 알부민/글로불린 비는 NaF 농도와 관계가 없는 것으로 관찰되었다. 따라서 일정 이상 농도의 NaF 경구 투여는 흰쥐의 체중 및 지질성분을 증가시키는 것으로 판단되며, 이는 비만 및 이상지질혈증을 초래할 수 있을 것으로 추정된다.
