A study on various symptoms of chronic hepatitis treated with radix astragali and its regulative effect to levels of serum hormone 下载免费PDF全文
Ke-zhou Liu Zhong-hang Tong Ming-tai Zhang Wei-zheng Gu Zhi-rong Huang Bi-he Shen Pei-ren Cai Gui-lang Zhu Wen-nan He Lan-sheng Feng Lie-ming Ding Zhi Chen Jian-hua Jin Xiu-zhi Zhang Qian-yan Yu Shui-jin Tong Ping Ye 《中国结合医学杂志》1995,1(2):118-121
Sixty-seven cases of chronic hepatitis were treated with Radix Astragali. After treatment (2-month course), the clinical improvement rate in 38 cases of the Stagnation of the Liver-Qi and Deficiency of the Spleen type was 92.1%, and in 26 cases of the Deficiency of Liver Yin and Kidney Yin type was 88.5%, more effective than in the control group (P<0.05). The regulative effect to the levels of serum hormone was observed in the patients of the Stagnation of the Liver-Qi and Deficiency of the Spleen type treated with this medicine. The results showed that the levels of serum triiodothyronine, estradiol (female) and testosterone (male) were increased after treatment (1.40±1.38 ng/dl, 129.30±1.23 pg/ml and 496.24±1.47 ng/dl). Pre-treatment levels were 1.22±1.49 ng/dl, 104.60±1.45 pg/ml and 398. 17±1.55 ng/dl respectively (P<0.05); however, the level of serum prolactin (2.75±4.46 ng/ml) was lower after treatment than before treatment (3.20±3.82 ng/ml,P<0.05). No obvious changes were observed in the levels of serum follicle stimulating hormone, luteinizing hormone, thyroid stimulating hormone, thyroxine, triiodothyronine uptake ratio and cortisol after treatment. 相似文献

本文就宁夏医学院附属医院肿瘤外科1984~1994年6月收治的603例胃癌中的5例残胃癌患者,结合文献对其发病年龄,部位,发病率,生物学行为、临床表现、早期诊断以及残胃癌与胃大部切除术式的关系等进行了探讨,认为:1.以外科手术为主的综合治疗是残胃癌的治疗原则;2.定期随诊是早期发现残胃癌的关键,3.B-Ⅰ式吻合或Roux-en-Y式吻台取代B-Ⅱ式吻合,可避免十二指肠液返流入残胃,减缓残胃癌的发生。 相似文献

Microtubules were purified by using two cycles of assembly and disassembly processes on fresh brain homogenates from 30 guinea pigs. The yield was about 60 mg. The effect of tetrandrine on tubulin was determined by spectrophotometric analysis and electron microscopy. In addition, we used the indirect immunofluorescent method including tubulin antibody to locate the presence of microtubules in 3T3 cells by fluorescence microscopy. The effects of colchicine and P204 were studied for comparison at the same time. The results showed that colchicine can effectively depolymerize microtubules, while tetrandrine showed aggregation, and in a different manner. The shape and structure of microtubules were definitely destroyed by colchicine, but were not affected by P204 which protected against the destructive effect of tetrandrine. This result indicated the safety of using a combination of P204 and tetrandrine in the treatment of silicosis. 相似文献

In vitro metabolic study of temsirolimus: preparation, isolation, and identification of the metabolites. 总被引:1,自引:0,他引:1
The in vitro metabolism of temsirolimus, (rapamycin-42-[2,2-bis-(hydroxymethyl)]-propionate), an antineoplastic agent, was studied using human liver microsomes as well as recombinant human cytochrome P450s, namely CYP3A4, 1A2, 2A6, 2C8, 2C9, 2C19, and 2E1. Fifteen metabolites were detected by liquid chromatography (LC)-tandem mass spectrometry (MS/MS or MS/MS/MS). CYP3A4 was identified as the main enzyme responsible for the metabolism of the compound. Incubation of temsirolimus with recombinant CYP3A4 produced most of the metabolites detected from incubation with human liver microsomes, which was used for large-scale preparation of the metabolites. By silica gel chromatography followed by semipreparative reverse-phase high-performance liquid chromatography, individual metabolites were separated and purified for structural elucidation and bioactivity studies. The minor metabolites (peaks 1-7) were identified as hydroxylated or desmethylated macrolide ring-opened temsirolimus derivatives by both positive and negative mass spectrometry (MS) and MS/MS spectroscopic methods. Because these compounds were unstable and only present in trace amounts, no further investigations were conducted. Six major metabolites were identified as 36-hydroxyl temsirolimus (M8), 35-hydroxyl temsirolimus (M9), 11-hydroxyl temsirolimus with an opened hemiketal ring (M10 and M11), N- oxide temsirolimus (M12), and 32-O-desmethyl temsirolimus (M13) using combined LC-MS, MS/MS, MS/MS/MS, and NMR techniques. Compared with the parent compound, these metabolites showed dramatically decreased activity against LNCaP cellular proliferation. 相似文献

Since 1985, on the basis of anatomic study of dorsal pedal artery, thumb and radial side of palm reconstruction have been successfully performed in one stage by using opposite composite dorsal pedal flap including the second toe, the second metatarsal and the first toe web. Because they were all distributed by dorsal pedal artery and great saphenous vein, dissecting these tissues was not difficult. Good function and cosmetic appearance were achieved following reconstruction. 相似文献
