Abstract:AIM: The present study aimed to investigate the histomorphometric and immunohistochemical impacts of vitamin K2 on guided bone regeneration (GBR) in calvarial critical-size defects (CSDs) in diabetic rats.
METHODS: A total of 30 rats were used in this study, comprising 12 non-diabetic (control) rats and 18 with streptozotocin-nicotinamide-induced experimental Diabetes mellitus (DM).在所有大鼠中,都创建了两个颅骨CSD:一个缺陷(e),othER用牛衍生的骨移植物和基于胶原蛋白的可吸收膜(GM)处理。研究组如下:对照大鼠施用盐水(n = 6,C-E和C-gm组)或维生素K2(n = 6,CK-E和CK-GM组)和糖尿病大鼠施用盐水(n = 6,DM-E和DM-GM组)或DM-GM组)或维生素K2或维生素K2(n = 6,DMK-E和DMK-E和DMK-E和DMK-e-e)。盐水或维生素K2给药4周后,将大鼠安乐死。 Bone defect healing and new bone formation were assessed histomorphometrically, and osteocalcin and osteopontin levels were examined immunohistochemically.
RESULTS: Percentage of new bone formation was greater in CK-GM vs. CK-E and in DMK-GM vs. DMK-E [D = 3.86(95%CI = 16.38-28.61),d = 1.86,(95%CI = 10.74-38.58),p <.05]。 CK-GM与CK-E的骨缺损愈合评分较高,DMK-GM与DMK-E [D = 2.69(95%CI = -2.12至-0.87),d = 3.28(95%CI = 0.98-1.91),分别为p <.05]。在CK-GM与CK-E中,骨钙素的表达水平升高,DMK-GM与DMK-E [D = 1.19(95%CI = 0.08-1.41),d = 1.10(95%CI = 0.02-1.22),分别为P <.05]。维生素K2在DMK-E与DM-E中增强了骨钙素的表达水平[D = 2.78,(95%CI = 0.56-1.53),p <.05],在DMK-gm vs. DM-gm中[d = 2.43,(95%ci = 0.65-2.10),p <.05],p <.05]。在用GM与E缺陷处理的缺陷中增强了骨桥蛋白的表达[C-GM与C-E,D = 1.56(95%CI = 0.38-2.01); CK-GM与CK-E,d = 1.91(95%CI = 0.49-1.72); DM-GM与DM-E,D = 2.34(95%CI = -1.12至-0.50); DMK-GM与DMK-E,D = 2.00(95%CI = 0.58-1.91),P <.05]。骨再生策略。
