摘要:[目的]觀察牡蠣、石決明、瓦楞子、珍珠母、紫貝齒、蛤殼 6 種介類中藥對大鼠甲狀腺腫大的影響。[方法]72 只健康 SD 大鼠隨機(jī)分為 9 組:正常組、模型組、陽性組及 6 個介類中藥組。每日灌胃丙硫氧嘧啶(0.15g·kg-1),連續(xù)造模 10d,稱量甲狀腺濕重,酶聯(lián)免疫法測血清 T3、T4、TSH 含量,觀察光鏡下甲狀腺的形態(tài)變化。[結(jié)果]模型組大鼠較正常組甲狀腺相對重量增加,T3、T4 含量降低,且均有顯著性差異(P<0.01),甲狀腺濾泡上皮細(xì)胞增生明顯;與模型組比較,牡蠣、蛤殼組使大鼠 T3、T4 含量均回升,且均有顯著性差異(P<0.05);牡蠣、蛤殼組甲狀腺濾泡上皮細(xì)胞增生不明顯,其他 4 種介類中藥組均有不同程度的增生。[結(jié)論]牡蠣、蛤殼對甲狀腺腫模型大鼠甲狀腺功能均有較好的改善作用。

Experimental Study of Six Testacean TCM "Endometriosis" Role on Goiter Model Rats Peng Qianqian, Hong Yin, Liao Guanghui Pharmacological College of Zhejiang Chinese Medical University, Hangzhou(310053)
Abstract:[Objective] To observe the effects of Oysters, Abalone shell, Concha arcae, Mother-of-pearl, Concha cypraeae, Clamshell, these six testacean TCM on the goiter rats. [Method] 72 healthy SD rats were randomly divided into nine groups: normal group, model group, positive group and six testacean TCM groups. Rats were given daily propylthiouracil (0.15 g·kg-1), continuous modeling for 10d, weighing thyroid wet weight,assaying T3, T4 and TSH contents in serum by ELISA, observing the morphological changes of thyroid under light microscope. [Result] Rats in the model group compared with normal group in - creased the relative weight of thyroid, reduced the content of T3,T4, and there was a significant difference( P<0.01), thyroid follicular epithelial cell hyperplasia
was obvious; compared with the model group, Oysters and Clamshell group made the content of T3,T4 in rat rebound, and there was a significant difference (P<0.05);Oyster and Clamshell group’s thyroid follicular cell hyperplasia were not obvious, while the hyperplasia had different levels for the other 4 kinds of testacean TCM. [Conclusion] Oysters and Clamshell were better to improve the thyroid function of the goiter model rats.

介類指有甲殼的蟲類或水族,介類中藥是指將介類之殼、甲作為藥用部分,在中醫(yī)藥理論體系指導(dǎo)下運(yùn)用的藥物。藥性多偏寒涼,大多味咸,主入肝經(jīng), 性均沉降。其使用主要受“介類潛陽”“咸能軟堅(jiān)”等藥性理論指導(dǎo),功效表達(dá)主要為平肝潛陽、軟堅(jiān)散結(jié)、滋陰安神、煅用內(nèi)服“制酸止痛”、外用“斂瘡生肌”等。本文基于介類中藥多味咸而具軟堅(jiān)散結(jié)作用,選定臨床常用的 6 種介類中藥,通過甲狀腺腫模型大鼠,來探討介類中藥對大鼠甲狀腺腫大的療效影響,以期能為臨床準(zhǔn)確的運(yùn)用介類中藥及“咸能軟堅(jiān)”理論提供實(shí)驗(yàn)依據(jù)。
