药敏纸片的质量控制研究

目的：探讨和研究药敏纸片质量控制的方法。方法：以克拉霉素药敏纸片为例，参照美国临床实验室标准化委员会(NCCLS)和联邦法规全书(CFR)的方法，建立一套药敏纸片质量控制的指标，包括鉴别、检查及含量测定。结果：采用专属性较强、灵敏度较高的TLC法进行鉴别，最低检出量为50μg；制订纸片的的直径、重量差异、含量均匀性及干燥失重作为检查项，采用短小芽孢杆菌(Bacillus pumilus)[CMCC(B)63202]作为检定菌，进行含量测定。结论：建立的克拉霉素药敏纸片质量标准能够控制其质量，可作为其他抗生素药敏纸片建立质量标准的参考。     

A study on the expression of TGF-beta 1/T beta R II in laryngeal carcinoma]

OBJECTIVE: To explore the expression of TGF-beta 1/T beta R II in laryngeal carcinoma. METHOD: Immunohistochemical study using SP kit in 53 cases. RESULT: The expression of TGF-beta 1 was decreased in carcinoma tissues when compared with peri-cancer controls (P < 0.05). There wasn't difference in T beta R II expression when compared with peri cancer controls (P > 0.05). But it was correlated with the stage, differentiation and lymph node metastasis of laryngeal carcinoma. CONCLUSION: TGF-beta 1/T beta R II may involve in the histogenesis and development of laryngeal carcinoma. The decreased expression of TGF-beta 1/T beta R II may serve as an important molecular marker of laryngeal carcinoma.     

喉鳞癌瘤内微血管及微淋巴管形态计量研究及临床意义

目的:研究喉鳞癌瘤内微血管和微淋巴管形态、分布、密度,以及相关临床意义。方法:采用5’-Nase-AlPase双重酶组织化学法和HE染色对40侧喉鳞癌标本冰冻切片进行研究。结果:光镜下微血管呈蓝色,微淋巴管呈棕色。除转移组微血管密度显著高于未转移组外,与其余临床指标均未见相关性。结论:瘤内微血管密度与淋巴转移有明显相关,而微淋巴管密度未发现明显临床意义,其机制待深入研究。

Potassium increases intracellular calcium simulating progesterone action in human sperm

Progesterone (P) and zona pellucida are known to induce acrosome reaction in human sperm by increasing cytosolic calcium. High concentrations of potassium ions (K+) improve the rate of acrosome reaction in human sperm in vitro. This article determined whether the effect of K+ on the acrosome in human sperm is mediated by increasing intracellular calcium ([Ca2+]i). The effect of K+ on [Ca2+]i was examined by using Fura 2 as the fluorescent indicator. The effect of K+ and P on [Ca2+]i in sperm and the involvement of ion channels was compared. Motile sperm were collected by the swim-up method from semen of healthy volunteers and capacitated overnight in BWW containing 0.5% BSA. Incubation of capacitated sperm with different concentrations of potassium chloride (1.25-20 mM) resulted in dose-dependent increase in [Ca2+]i similar to that observed with P. The increase in [Ca2+]i by K+ and P was blocked by the addition of EGTA, a Ca2+ chelator. K+-induced change in [Ca2+] was not altered by the addition of dihydropyridine derivatives. The combined treatment of K+ (20 mM) and P (0.75 microg/mL) caused an additive effect on the increase in [Ca2+]i. It would appear that human sperm plasma membrane possess different Ca2+ channels responsive to P and K+.
