Animal experiment: | Mice[2]8-12 weeks old C57/BL6 male mice between 23-25 g receive intraperitoneal (i.p.) injections of 50 mg/kg Streptozotocin (STZ), dissolved in 100 mM citrate buffer pH 4.5, for five consecutive days. Diabetic mice (13-week-old) are randomly divided into three groups: 1) untreated group; 2) Nedocromil group, with Nedocromil released at the rate of 30 mg/kg per day from a subcutaneous (s.c.) pellet implantation; and vehicle group, with an inactive pellet implanted. Normal mice (non-diabetic) and normal mice that receive Nedocromil (30 mg/kg per day) are also included in this study for comparison. All sample groups included 15 mice (n=15)[2]. |

Nedocromil suppresses the action or formation of multiple mediators, including histamine, leukotriene C4 (LTC4), and prostaglandin D2 (PGD2).
Nedocromil inhibits the release of histamine, LTC4, and PGD2 from mast cells challenged with antigen (with IC30 values of 2.1 μM, 2.3 μM, and 1.9 μM, respectively) and with anti-human IgE (IC30 values of 4.7 μM, 1.3 μM, and 1.3 μM, respectively)[1].
Nedocromil-treated diabetic mice show significantly improved heart function compared with controls. The contractility and relaxation forces show similar improvements. However, the cardiac function of Nedocromil-treated diabetic mice remains significantly impaired when compared with normal mice. Nedocromil can significantly improve cardiac function in mice with diabetic cardiomyopathy, but the treatment cannot restore normal function[2].

体内配方配制方法:取 μL DMSO母液,加入 μL PEG300,混匀澄清后加入μL Tween 80,混匀澄清后加入 μL saline,混匀澄清。
1. 首先保证母液是澄清的;
2.
一定要按照顺序依次将溶剂加入,进行下一步操作之前必须保证上一步操作得到的是澄清的溶液,可采用涡旋、超声或水浴加热等物理方法助溶。
