目的:研究组蛋白去乙酰化酶抑制剂(histone deacetylase inhibition HDACi):丁酸钠(Sodium Butyrate NaB)腹腔连续给药对
BALB/C小鼠体重增长及器官发育的影响。方法:20 只健康,3 周BALB/C 小鼠随机分成2 组(丁酸钠组和对照组);丁酸钠组腹腔
注射丁酸钠(NaB)1.2 g/ Kg·d,连续21 天;对照组同时间腹腔注射等量生理盐水。21 天后,测量体重;行4 %多聚甲醛灌注、固定,
取心脏,肝脏,脾脏,肺脏,肾脏,脑组织以及小肠组织器官,做石蜡切片,HE 染色两组比较有无器官损害。结果:1. 丁酸钠组与对
照组比较,两组动物体重增长良好,平均增长11 g,两组间无统计学差异(P>0.05)。2.HE 染色见丁酸钠组:心肌细胞无变性,坏死,
无炎性细胞浸润,无肉芽组织形成;脾脏红、白髓结构清晰,脾窦无扩张,未见炎性细胞浸润;肺间质无扩张,充血,未见纤维化,肺
泡无水肿;肾小管上皮细胞无变性坏死,肾间质未见水肿;脑细胞周围间隙和小血管间隙无增宽;肠道纤毛上皮排列整齐,肠壁无
出血,坏死,无渗出;肝细胞围绕中央静脉呈放射状排列,细胞无水肿,无胆汁淤积。未发现上述器官的病理变化。结论:丁酸钠长
期腹腔给药安全,无明显毒副作用。 |

Objective:Research the organ toxicity of Histone deacetylase inhibition (HDACi); SodiumButyrate ( NaB ) through
the continuous iintraperitoneal injection in BALB/C mice.Methods:Twenty healthy, 3W BALB/C mice were randomly divided into 2
groups (NaB group and the control group), Intraperitoneal injection of NaB 1.2 g/Kg·d for 21 days (NaB group); intraperitoneal injection
of equivalent physiological saline for 21 days to be the control group. After measuring the weight gain, 4%paraformaldehyde glutaraldehyde
perfusion fixation, do the HE test of heart, liver, spleen, lung, kidney, brain tissue and intestinal tissue pathological slices.Results:1.
NaB group compared with the control group, average growth in 11 g. There is no statistical difference between the two groups(P>0.05).
2. The organ HE staining of NaB group. Cardiac muscle cell have no degeneration, necrosis, or inflammatory cell infiltration, and granulation
tissue formation; Spleen's red and white pulp structure is clear, there is no expansion of splenic sinus, and inflammatory cell infiltration;
Pulmonary interstitial have no expansion, congestion, or fibrosis, and no alveolar edema; Renal tubular epithelial cells have no
degeneration necrosis, renal interstitial have no edema. Brain cell's peripheral clearance and small vessel have no broaden; Intestinal ciliated
epithelium neatly, intestinal wall without hemorrhage, necrosis, and leakage. liver cells lie in a radial pattern around the central vein,
without edema or cholestasis. Did not observe any pathological changes on the above organ.Conclusion:Sodium butyrate intraperitoneal
injection is safe for a long time, and have no obvious side effects. |
