AIM: To investigate the mRNA changes of L-type Ca~(2+) channel ?_(1C) subunit (CaL-?_(1C)) and Na~+-Ca~(2+) exchanger (NCX) in the atria of renovascular hypertensive rats. METHODS: Two-kidney one-clip Goldblatt hypertensive Sprague-Dawley rats were divided into three groups 1 week after operation, HD group was treated with 250 mg/d diltiazem, LD group was treated with 50 mg/d diltiazem, control group (C group) was treated with vehicle. After 4 weeks treatment, semiquantitative RT-PCR was used to estimate the mRNA changes of CaL-?_(1C) and NCX, and GAPDH was used as internal control. RESULTS: Systolic blood pressure in LD group was comparable with C group, and that in HD group was decreased to normal level after diltiazem treatment. In C group, CaL-?_(1C) mRNA level were 2.5, 2.4 and 2.1 times of S, HD and LD group, and NCX mRNA level were 1.9, 1.6 and 2.1 times of S, HD and LD group. There were no significant difference in the mRNA level of CaL-?_(1C) and NCX among S, HD and LD group. CONCLUSION: The mRNA levels of CaL-?_(1C) and NCX are upregulated in the atria of hypertensive rats. Ca~(2+) antagonist inhibits their upregulation independent of blood pressure.

We developed a novel method for the rapid determination of lysozyme using a new fluorogenic substrate that consists of a cationic aluminum phthalocyanine ( tetra ( trimethylammonio ) aluminum phthalocyanine, TTMAAlPc ) , and an anionic mucopolysaccharide ( heparin, HP ) . We found that fluorescence from the cationic aluminum phthalocyanine, a red-region fluorescence probe, was quenched significantly in acidic media in the presence of low concentrations of anionic mucopolysaccharide heparin ( HP) bearing anionic sulfonic acid groups, because of induced aggregation. The practically non-fluorescent substrate degraded into small molecular fragments upon the hydrolysis of lysozyme, and thus the phthalocyanine molecules aggregated in HP were released, resulting in significant fluorescence recovery in the reaction system. This phenomenon forms the foundation of the proposed method. The reaction mechanism was determined using fluorescence spectroscopy and fluorescence anisotropy techniques. Factors that affected the determination were investigated. Under optimal conditions, the linear range was 0. 2-2 mg/L, and the detection limit was 0. 015 mg/L. The developed method is easy to operate and has good selectivity and sensitivity. This method was used in the analysis of practical samples of lysozyme, and the results were in agreement with those determined by a conventional turbidimetric method.
