Serum cardiac troponin T (cTnT) and CKMB (mass) were analysed in three groups of patients. The first group (n=32) were patients
with acute coronary syndromes including myocardial infarction. The second group (n=35)were patients with hypertension. The
third group (n=24) were patients who had succumbed to non cardiac diseases. In all 3 groups, cardiac troponin T was elevated
when compared with controls (p<0.001). However, CKMB elevation was not significant in all groups. CKMB levels correlated well
with troponin T levels only when CKMB was greater than 50 ng/ml (r=1.00). Small elevations of troponin T identifies minimal
cardiac necrosis and patients can benefit from early invasive therapy. 相似文献

Bone metastases are a serious problem in patients with advanced cancer disease and their presence usually signifies serious morbidity prior to the patient’s death. In breast cancer patients the incidence of bone metastasis is observed to be very high at 70 %, as seen during post-mortem examination. Bone metastasis is difficult to diagnose, treat or follow clinically without radiological tools. This study was designed to evaluate the utility of a novel bone resorption marker–serum tartrate-resistant acid phosphatase 5b (TRACP5b) and the bone formation marker such as serum total alkaline phosphatase (ALP), in comparison with whole body skeletal scintigraphy with Technetium99m MDP for the diagnosis of bone metastases (BM) in breast cancer (BC) patients. This study is intended to help the clinician to diagnose bone metastasis without resorting to radiological tools, as they are not cost effective and carry the risk of radiation. Experimental design: Four groups of samples were analysed. 1st group consists 52 normal female (cancer free women), 2nd group consists 38 BC patients without bone metastasis, 3rd group consists 27 breast cancer patients with limited bone metastasis (3 or less than 3 skeletal lesions) and 4th group consists 35 breast cancer patients with extensive bone metastasis (4 or more than 4 skeletal lesions), conformed by whole body skeletal scintigraphy with Technetium99m MDP. One way ANOVA was used to compare serum TRACP5b and serum ALP among these groups. Both serum TRACP5b and serum ALP are not markedly elevated in limited bone metastasis but are strongly elevated in extensive bone metastasis (p < 0.0001). As seen in this study the biochemical bone resorption marker, serum TRACP5b, abnormally increased in extensive bone metastasis of breast cancer patients and can be used as a specific marker for bone metastasis in lieu of radiological tools. 相似文献

The present study was carried out to explore the altered lipid, lipoprotein and apoprotein abnormalities along with lipoprotein
(a) in chronic kidney disease patients with stage I to V which were further divided into group 1 (stage I and II), group 2
(stage III and IV) and group 3 (stage V). 50 chronic kidney disease patients with stage I to V and 20 healthy normal subjects
as controls were recruited for this study. Among the various parameters tested triglyceride levels were high in group 1 and
2, whereas VLDL cholesterol, Lp (a) and apo B levels were significantly high in all the groups when compared to controls (P<0.05).
However, LDL cholesterol level was significantly low in group 3 only as compared to control group (P<0.05). Apoprotein AI
values also showed significant decrease in all groups as compared to controls (P<0.05). Though total cholesterol levels in
group 1 and LDL levels in group 1 and 2 were higher than controls, but the values attained not statistically significant (P>0.05).
In conclusion high levels of VLDL cholesterol, Lp (a), apo B and low levels of apoprotein AI as reported in this study are
the major lipid disorders in the development of cardiovascular complications at all the stages in these patients. 相似文献

In the present study primary involution osteoporosis and vitamin D levels were studied in 60 subjects including thirty controls.
The biochemical analysis of serum calcium, phosphorus, ALP, albumin and vitamin D3 (1,25-(OH)2 D3) levels were significantly decreased in osteoporotic patients when compared to non-osteoporotic control group. There was
a significant correlation of magnitude of sun exposure with 1,25-(OH)2 D3 levels. Similarly, vitamin D intake in the diet has a significant correlation with 1,25-(OH)2 D3 concentration. However, no correlation could be obtained between vitamin D3 levels with increasing age. Among the biochemical markers serum calcium, phosphorus, ALP and albumin could not be correlated
with 1,25-(OH)2 D3 levels. 相似文献

Matrix metalloproteinases (MMPs) play important role in the pathogenesis of coronary artery disease (CAD). 5A allele of -1612 5A/6A polymorphism of MMP-3 is associated with two fold higher activity than 6A allele. Present study was designed to analyse the association of this polymorphism with CAD in Indian population. Subjects included in the study were patients with stable angina (n=35), unstable angina (n=53), patients with recent event of myocardial infarction (MI) (MI Group-1, n=56) and patients at presentation of the acute MI (MI Group-2, n=49). Controls were healthy individuals (n=99). Genotyping of MMP-3 5A/6A polymorphism was carried out by PCR-based restriction digestion method. The genotype distribution of patient groups did not deviate from controls. Serum MMP-3 levels were significantly elevated at presentation of the acute MI by 36.8% (P=0.031) as compared to controls and more associated with 6A genotype suggesting discrepancy between in vitro transfection experiment and peripheral MMP-3 levels. 相似文献

The present study comprised 100 patients of essential hypertension who were screened for fasting hyperinsulinemia, which was
detected in 77% cases. Twenty such hyperinsulinemic cases were subjected to 4 weeks of dietary control phase followed by 6
weeks of omega-3 fatty acids substitution [either 0.6 g/d (group 1) or 1.2 g/d (group 2)]. The mean basal fasting plasma insulin
levels were significantly higher (p<0.001) in patients of hypertension when compared to normal controls (126.51±80.36 and
19.35±12.61 μU/ml respectively). At the end of 4 weeks of diet control only, no significant change was observed in any parameter.
After substitution of omega-3 fatty acid, a significant reduction of fasting plasma insulin levels in both group 1 (29%) and
group 2 (22.8%) was observed (p<0.001). Significant reduction of systolic and diastolic blood pressure (16.4% and 25% respectively),
serum cholesterol, triglycerides and low density lipoprotein was also noted in both groups (p<0.001), while high density lipoprotein
increased by ∼8 mg% in both groups. Thus omega-3 fatty acid substituion in low dose along-with curtailment of dietary omega-6
fatty acid may be used as an adjunctive measure in the management of essential hypertension. 相似文献

Based on our demonstration earlier that ethanol extract, water extract and a compound purified from garlic possessedin vitro antitubercular activity against drug resistant and susceptibleMycobacterium tuberculosis, we tried the effect of garlic extract in 30 patients of tubercular lymphadenitis. For ethical considerations, two groups
of patients, 30 each, were given antitubercular therapy (ATT) consisting of isoniazid, rifampicin, ethambutol and pyrazinamide
for 30 days. For the next 15 days (31 to 45 days) group 1 patients received 3–6 garlic pearls per day in addition to ATT while
group 2 patients received ATT only. From 46th day onwards both the groups received ATT only for 6–8 months. Antitubercular
activity of the serum samples collected on 45th day was assessed by its effect on the growth ofM. tuberculois. The serum of group 1 patients showed significantly much higher antitubercular activity than that of group 2 patients. Further,
there was relief of dyspeptic symptoms caused by ATT therapy in patients of group 1 with garlic plus ATT therapy but no change
in group 2 patients with ATT only. Liver function and hematological tests were normal in both the groups after 6 months of
therapy. Garlic extracts or compounds have a good potential as antitubercular(s) drug if given as a supplement to ATT. 相似文献

老鸦瓣群(Amana群)是百合科中的一个东亚特有类群,仅分布在中国中东部、日本和朝鲜半岛。该类群在形态上与广义郁金香属Tulipa L.相似,但也具有与子房近等长的花柱以及2-3(-4)个苞片等与郁金香属不同的形态特征。有关该类群是否应置于郁金香属中或是否应独立为属的问题长期以来存在争议。为了澄清该问题,我们对产于中国的Amana群进行了广泛的标本室和野外形态观察,并采用分支系统学方法,对该类群3个种以及郁金香属的其他15种植物(包括土耳其的3个种)的28个形态性状数据进行了分支分析。结果表明广义郁金香属并非是一个单系类群。Amana群与广义郁金香属的其他4个组sect. Orithyia、sect. Eriostemones、sect. Leiostemones、sect. Tulipanum以及Lloydia属的两个种共同构成一个大支的3个分支。我们对广义郁金香属5个组共19种植物的ITS以及trnL-F分子序列综合分析的结果也表明：sect. Tulipanum、sect. Leiostemones、sect. Eriostemones和sect. Orithyia构成一大支,Amana群和猪牙花属的Erythronium sibiricum构成另一大支。因此,我们认为Amana群应从广义郁金香属中独立出来,恢复其老鸦瓣属Amana Honda作为属的分类地位。 相似文献

Long-term exposure to organophosphate pesticides (OPs) without acute poisoning can lead to various OPs. Environmental exposure to organophosphate pesticides may be associated with depression and suicide attempts in a population living in a rural agricultural area. Patients (n = 149) suffering from major depressive disorder (with and without attempted suicide) and a control group of healthy individuals (n = 64) who had been living in the same rural district for at least 1 year were selected. Red blood cell acetylcholine esterase (RBC-AChE) activity was examined as the basis of evaluating the degree of chronic environmental exposure to OPs residues. There were negative association between RBC-AChE activity levels and suicide attempts, the number of past suicide attempts and hopelessness levels in the depressive patients. The results of the study may support the idea that environmental exposure to OPs may be associated with mental health in individuals living in agricultural districts who are not farmers or working in occupations with access to OPs. 相似文献

Introduction:
This study aimed to assess whether heart fatty acid-binding protein (H-FABP) and glycogen phosphorylase isoenzyme BB (GPBB) could be used for the accurate diagnosis of acute myocardial infarction (AMI) in acute coronary syndrome (ACS) patients.Materials and methods:
The study included 108 ACS patients admitted to a coronary unit within 3 h after chest pain onset. AMI was distinguished from unstable angina (UA) using a classical cardiac troponin I (cTnI) assay. H-FABP and GPBB were measured by ELISA on admission (0 h) and at 3, 6, 12, and 24 h after admission; their accuracy to diagnose AMI was assessed using statistical methods.Results:
From 92 patients with ACS; 71 had AMI. H-FABP and GPBB had higher peak value after 3 h from admission than cTnI (P = 0.001). Both markers normalized at 24 h. The area under the receiver operating characteristic curves was significantly greater for both markers in AMI patients than in UA patients at all time points tested, including admission (P < 0.001). At admission, the H-FABP (37%) and GPBB (40%) sensitivities were relatively low. They increased at 3 and 6 h after admission for both markers and decreased again after 24 h. It was 40% for H-FABP and approximately 2-times lower for GPBB (P < 0.01). In AMI patients, both biomarkers had similar specificities, positive- and negative-predictive values, positive and negative likelihood ratios, and risk ratios for AIM.Conclusion:
H-FABP and GPBB can contribute to early AMI diagnosis and can distinguish AMI from UA. 相似文献15.

An audit of 2509 patient specimens analyzed for both total thyroxine (TT4) and free thyroxine (FT4) by the ACS-180 automated
chemiluminescence immunoassay analyzer revealed that there were 219 discrepancies (8.7% of the total). A discrepancy was defined
as one analyte within its reference range and the other outside. The discrepant results were divided into 4 groups: group
A: normal TT4, but decreased FT4, 101 patients (4.0%); group B: increased TT4, normal FT4, 78 patients (3.1%); group C: decreased
TT4, normal FT4, 34 patients (1.4%); and group D: normal TT4, increased FT4, 6 patients (0.2%). TSH measurements were available,
by a 3rd generation chemiluminescent assay, in 142 of these patients, and were consistent with the FT4 result in 72 patients, with
TT4 in 61 cases and with neither in 9 patients. The clinical diagnosis was investigated in a subgroup of 43 endocrine patients.
Thirteen of the 20 endocrine patients in group A were diagnosed as hypothyroid, with a measured serum TSH, in 11 of them,
of median 14.6, range 1.2 to 46.2 μlU/ml. Eleven of the 19 endocrine patients in group B were on thyroid replacement, with
a measured serum TSH, in 7 of them of <0.01 μlU/ml. The audit of current laboratory practice led to a suggestion to replace
the current thyroid function screening strategy of measuring both TT4 and FT4 by the combination of FT4 and TSH. The reasons
for the discrepancies and the alternative strategies for screening of thyroid function are discussed. 相似文献
