目的 观察六味地黄汤及三个“一补一泻”药对对肾阴虚模型小鼠下丘脑-垂体-肾上腺(HPA)轴功能及肾上腺形态的影响.方法 将小鼠随机分为空白组、模型组和给药组(六味地黄汤组、山茱萸-牡丹皮组、熟地黄-泽泻组、山药-茯苓组)共6个试验组;连续9d分别灌胃给予以上对应药物;第5～9天,除空白组灌胃蒸馏水外,其他各组按50 mg/kg体质量每天灌胃氢化可的松注射液,称体质量,测定环磷酸腺苷(cAMP)、环磷酸鸟苷(cGMP)、促肾上腺皮质激素(ACTH)、皮质醇(Cor.)含量,观察肾上腺病理切片.结果 肾阴虚模型小鼠体质量、血浆cGMP含量降低,血浆cAMP、血清ACTH、Cor.含量升高,与空白组比较,差异有统计学意义(P＜0.01),肾上腺组织受损;与模型组比较,六味地黄汤能上调模型小鼠体质量、血浆cGMP含量,下调血浆cAMP含量、血清ACTH、Cor.含量(P＜0.05,P＜0.01),修复受损肾上腺组织;山茱萸-牡丹皮药对能下调模型小鼠血浆cAMP、血清ACTH含量(P＜0.01),修复受损肾上腺组织.结论 六味地黄汤能改善肾阴虚证,其作用机制可能与其降低垂体分泌的ACTH含量、下调肾上腺分泌的Cor.含量,改善HPA轴的功能及肾上腺形态有关.其中山茱萸-牡丹皮药对是该方改善肾阴虚证的主要药效物质基础.     

30例妊娠高血压综合征患者锌、铜、镉的测定分析

本文研究了30例不同程度的妊高征患者,并以同期正常孕妇30例作相应对照。共采集母血清、脐血清、胎盘标本各60份,采用原子吸收分光光度计测定其中锌、铜、镉的含量。结果表明:妊高征孕产妇组(实验组)母血清锌明显低于正常孕产妇组(对照组),(P<0.01),铜及铜/锌比值高于正常孕产妇组(铜值P<0.05,铜/锌比值P<0.01)。实验组母血清和胎盘中镉高于对照组(P<0.05);实验组与对照组的脐血清和胎盘中锌、铜及铜/锌比值无统计学差异,(P>0.05);实验组和对照组母血清、脐血清和胎盘中锌、铜、铜/锌比值无相关关系(r<0.05,P>0.05);脐血清与胎盘中锌及铜/锌比值部分呈现相关关系(锌值r=0.44,P<0.05;铜/锌比值r=0.38,P<0.05)。两组的胎盘锌含量明显高于母血清和脐血清锌含量,(P<0.01)。结果提示:母血清锌、铜/锌比值,母血清镉及胎盘镉可能与妊高征的发生有一定关系;胎盘有积锌现象;妊高征患者母血清锌降低并不影响胎盘和胎儿锌水平;胎盘锌、铜变化可能较母血清锌、铜变化更能反映胎儿锌状况。

硒与铜、锌、锰对小鼠肝脏中谷胱甘肽含量的共同影响

为探讨硒与铜、锌、锰共存时对小鼠肝脏中谷胱甘肽(GSH)含量的影响,使用氢化物原子化法及高效液相色谱法(HPLC)分别测定了在基础饲料中以不同组合拌入4种微量元素和对照各组小鼠肝脏中硒及GSH的含量。结果表明,1.铜+硒组、锌+硒组、锰+硒组肝脏中硒的含量均显著低于纯硒组(P<0.01),说明铜,锌,锰对硒的吸收有拮抗作用,提示在使用硒制剂时,若铜,锌,锰共存应适当增加硒的用量2.4组肝脏中GSH含量显著低于正常组(P<0.01),硒可促进还原型的GSH转化为氧化型的谷耽甘肽(GSSG),加锌后对此转化有叠加作用,加锰则有抑制作用,加铜无影响。

The alteration of plasma's zinc and copper levels in patients with burn injuries and the relationship to the time after burn injuries

INTRODUCTION: Burn injury is a medical problem as well as a social burden on the national health services in developing countries. Trace elements have important roles in wound healing and act as antioxidants. In this study, zinc (Zn) and copper (Cu) levels in plasma of burned patients and their relationship with the burn surface area and time-related pattern are determined in the admitted patients after burn injury. METHODS: 37 patients were divided into two groups: Group 1 consisted of 16 patients with burn injuries less than 20 percent of the total burn surface area, and Group 2 consisted of 21 patients with burn injuries between 20 and 40 percent of the total burn surface area. The control group consisted of 20 subjects. The Zn and Cu levels were determined one, three, seven and 14 days after the occurrence of burn injury. These trace elements were determined using atomic absorption spectrophotometer. RESULTS: These trace elements in plasma significantly decreased on all days after admission and the levels were lower than those of the control group. There was no significant relationship between Groups 1 and 2 in Cu and Zn concentrations on different days. We did not find any difference between burn surface area and Zn and Cu concentrations in these groups. CONCLUSION: Based on the critical role of plasma's Zn and Cu rate in wound healing and their relationship in decreasing the burn injury, it is important that patients having burn types II and III take Zn and Cu supplements continuously as micronutrients after burn injury.

Treatment of deficiency of spleen energy with zhenqi fuzheng chongji and its effect on Zn, Cu and Mg in serum

This article reports that there is a good response, with an effective rate of 96.2% in the treatment of the deficiency of Spleen energy (DSE) with Zhenqi Fuzheng Chongji (ZQFZCJ). The serous level of ZQFZCJ and the serum concentrations of Zn, Cu and Mg in 53 patients with DSE and in 83 normal subjects were measured with atomic absorption spectrometric analysis. In contrast to the normal subjects, the concentrations of Zn and Mg were decreased and that of Cu and the ratio of Cu/Zn increased in the patients before treatment (P greater than 0.01-0.05). After treatment, however, the concentrations of Zn and Mg became increased (P less than 0.001, P less than 0.05), and the ratio of Cu/Zn decreased (P less than 0.001). The authors conclude that there is some relationship between these three elements and DSE, and the mechanism for the treatment of DSE with ZQFZCJ. ZQFZCJ, rich in trace elements, may provide trace elements for the body, improve the metabolism, transportation and utilization of the trace elements in the body, and activate various enzymes, thus regulating and maintaining the homeostasis, i.e. "supporting in deficient patients".     

Clinical significance of the measurement of trace elements in the gastric mucosa and their oxides in patients with spleen diseases and gastric cancer

The gastric mucosa trace elements and oxides were investigated with X-ray energy disperse analysis system in 41 cases of gastric disease due to Spleen deficiency. The differences in the change of the quantity of Zn, Cu, ZnO and CuO were very significant (P less than 0.05-0.001) in the gastric mucosa between normal area and focal area, between Spleen Qi deficiency and Spleen deficiency with Qi stagnation, and between benign gastric disease and gastric cancer. The experiments showed that: (1) The trace elements in the organism form its own system, the values being within the relatively constant scope. (2) The ratios of Zn/ZnO and Cu/CuO reflected "the rate of effectual utility" of Zn and Cu. (3) There was a very close internal relation between Spleen deficiency with Qi stagnation and gastric cancer. (4) The quantitative changes of Zn, Cu, ZnO, CuO, Zn/ZnO and Cu/CuO were related to pathologic change and the TCM syndrome pattern, and is worthy of further research.

Study on the pathophysiologic basis of classification of ‘spleen’ deficiency in chronic gastritis

Background Most of the studies on traditional Chinese medicine (TCM) ‘spleen’ deficiency syndrome in the recent 30 years were conducted only on the basis of single functional index, neglecting the study on the pathophysiologic internal relationship between spleen deficiency syndrome and gastric diseases in modern medicine. But it was at the subcellular molecular biological level that we explored the pathophysiologic basis of classification of spleen deficiency in chronic gastritis by detecting the bioactive substances in gastric mucosa nuclei and mitochondria. Methods By means of optical microscope, scanning electron microscope (SEM), transmission electron microscopy (TEM) and histochemical staining, we conducted histopathological, subcellular ultrastructural analysis and nuclei and mitochondrial ultrastructural analysis of gastric mucosa of 188 spleen deficiency patients and of 42 voluntary blood donors. At the same time, bioactive substances were measured by means of X-ray energy dispersive analysis system (EDAX) image analysis system, radioimmunoassay method and chemiluminescence method. Results The content of cAMP, superoxide dismutase (SOD), Zn and Cu in gastric mucosa, and the content of Zn and Cu in mitochondria decreased progressively in order of groups: healthy control (HC), spleen Qi deficiency without organic lesion (F-SQD), spleen Yang deficiency without organic lesion (F-SyangD), disease without symptoms group, spleen Qi deficiency with organic lesion (G-SQD), spleen Yang deficiency with organic lesion (G-SyangD), spleen Yin deficiency (SyinD) and spleen deficiency with Qi stagnation (SDQS), chronic spleen deficiency gastritis (CSG) and chronic atrophic gastritis (CAG); decreased in order of HC, intestinal metaplasia (IM)Ⅰa, IMⅠb, IMⅡa and IMⅡb, P&lt;0.05. The content of DNA, Zn and Cu in nuclei progressively increased in order mentioned above, P&lt;0.05.Conclusions The quantitative changes of gastric mucosal cAMP, SOD, Zn, Cu, of mitochondrial Zn, Cu and of nuclear DNA, Zn and Cu are not only the substance base on which the lesion of gastric mucosa tissue structure occurs, but also the substance base on which spleen deficiency is classified. G-SQD and G-SyangD were more likely to be found in low-grade or middle-grade CSG and CAG, while SyinD and SDQS in middle-grade or high-grade CSG, CAG and IMⅡb.
