Six consecutive day and night urine samples from 25 renal stone patients and 25 comparabe controls were collected and analysed for total mucoproteins, Tamm-Horsfall mucoprotein, & creatinine. In normal subjects the 24 hour, day and night urinary excretion of mucoprotein was 101.4±34.5, 58.2±20.1 and 40.5±19.3 mg respectively. The Tamm-Horsfall mucoprotein excretion was 43.9±18.4, 21.5±8.6 and 20.6±9.9 mg in respective samples. Stone formers excreted significantly higher amount of mucoprotein but not the Tamm-Horsfall mucoprotein. Furthermore, the diurnal variations was visible only for in case of total mucoprotein in both the groups. 相似文献

Total amylase activity, its isoenzymes and pancreatic to salivary ratio were studied in 33 healthy subjects and 52 patients with hepatobiliary and pancreatic malignancies of which 12 were with hepatocellular carcinoma, 12 with liver metastases, 9 with carcinoma of gall bladder, 6 with obstructive jaundice, 7 with periampullary carcinoma and 6 cases with carcinoma of pancreas. Total amylase was found to be elevated in carcinoma of pancreas and periampullary carcinoma compared to normal whereas in obstructive jaundice the values were decreased significantly (p<0.001). P (Pancreatic) fraction was found to be elevated significantly in all except in carcinoma of pancreas and obstructive jaundice. S (Salivary) fraction was decreased significantly in all except in carcinoma of pancreas. P/S ratio was elevated in hepatocellular carcinoma, obstructive jaundice, metastatic liver disease, gall bladder carcinoma and periampullary carcinoma (p<0.001) but in carcinoma of pancreas P/S ratio was low as compared to normal. This simple test of total serum amylase, P fraction and S fraction, P/S ratio can be utilised in differentiating various hepatobiliary and pancreatic malignancies. 相似文献

To examine the possible involvement of human B cell leukemia/lymphoma 2 (Bcl-2), CD4+ cells, hepatocyte growth factor (HGF), and metalloproteinase-9 (MMP-9), as biomarkers in early diagnosis of hepatocellular carcinoma (HCC), activities of these biomarkers in serum were demonstrated by the method of Enzyme Linked Immunosorbant Assay. Two groups of subjects (60 for each), were examined in this study; healthy controls and patients with HCC. The present results declare that, significant decrease in Bcl-2 (p ≤ 0.0001), and CD 4+ (p ≤ 0.001), while significant increase in HGF and MMP-9 (p ≤ 0.05). These findings imply an influence of these biomarkers by the existence of hepatic carcinoma that might reflect the progression of disease and a distinction between the pathological mechanisms involved in hepatic carcinoma. Since, the serum MMP-9 activity was significantly varied between each stage of HCC. An individual profile of the present investigated parameters was detected that might serve as an easy accessing serum marker to monitor the progression of hepatic cell disorders. 相似文献

Serum and amniotic fluid mucoprotein concentrations were estimated in normal and toxaemic pregnant women. The levels were
found to be higher in preeclampsia and eclampsia than the normal controls. Comparatively higher concentrations were observed
in amniotic fluid than serum. Data suggest that the estimation of serum and amniotic fluid mucoproteins may be useful in assessing
the severity of toxaemia of pregnancy and fetal well being. 相似文献

Zinc (Zn), copper (Cu), magnesium (Mg) and retinol levels were studied in serum and tissue of the patients with prostatic carcinoma (Ca), benign hyperplasia (BHP) and control subjects. Zinc and retinol levels were low in both serum and tissues of patients with carcinoma, while in BHP, both zinc and retinol level were decreased. Copper levels were high in serum and tissues of both BHP as well as carcinoma patients. Magnesium levels were elevated in both serum and tissues of cancerous patients. The results indicate that Zn, Cu, and Mg metabolism is disturbed in malignancy. 相似文献

The main aim of this study is association of serum copper and vascular endothelial growth factor (VEGF-A) in postmenopausal bleeding (PMB) patients. Blood samples were collected from female patients suffering with postmenopausal bleeding (n = 50) as well as healthy females as controls (n = 50). Serum copper levels were estimated by spectrophotometric method and serum VEGF-A by ELISA technique and compared with ultrasonographic measurement of endometrial thickness in both patients and controls. A significant increase in serum copper levels and an almost twofold increase in serum VEGF-A was observed in DUB patients when compared with controls. Correlation (r) between serum VEGF-A levels and endometrial thickness was 0.96. Odds ratio for copper, VEGF-A and combination of copper and VEGF-A was 0.0426, 0.0947 and 0.0313 respectively, in all these cases odds ratio was <1. The abnormal angiogenesis in PMB could be due to increased serum copper levels,which in turn stimulates factors like VEGF-A, thereby causing an increase in endometrial growth. 相似文献

Serum levels of leucine amino peptidase (LAP) was studied along with bilirubin, aspartate transaminase (AST), alanine transaminase
(ALT), gamma glutamyl transpeptidase (GGT), alkaline phosphatase (ALP) and the ratio of AST/ALT and GGT/AST in 25 healthy
subjects and 52 patients with hepatobiliary malignancies of which 12 were with hepatocellular carcinoma, 12 with liver metastasis,
6 with obstructive jaundice, 9 with carcinoma of gall bladder, 6 with carcinoma of pancreas and 7 with periampullary carcinoma.
24 Of the 52 patients studied had jaundice and 28 were without jaundice.
LAP as compared to the other enzymes AST, ALT, GGT, ALP and AST/ALT ratio and GGT/AST ratio showed 100% elevation in obstructive
jaundice, carcinoma of gall bladder and pancreas and periampullary carcinoma, 91.7% elevation in hepatocellular carcinoma
and 83.3% elevation in liver metastasis. On comparing the levels of these enzymes in non jaundiced and jaundiced groups, LAP
was elevated in both jaundiced and non jaundiced groups in 95.8% and 92.9% cases respectively whereas the other enzymes AST
showed increase from 67.9% to 100%, ALT from 21.4% to 83.3%, GGT from 71.4% to 95.4% and ALP from 82.1% to 100% in non jaundiced
and jaundiced groups respectively indicating that LAP rises in hepatic dysfunction due to hepatobiliary malignancy whereas
the other liver function enzymes showed increased hepatic dysfunction due to hepatobiliary malignancy with the onset of jaundice
thereby indicating that LAP is a better indicator of hepatobiliary malignancy as compared to other enzymes.
The quantitative methods used for determination are reliable, accurate, simple, rapid and cost effective and therefore have
better application in a clinical setting. 相似文献

Hypomagnesaemia is common finding in current medical practice mainly in critically ill, post-operative patients and patients
admitted to ICU in tertiary cancer cases. Magnesium has been directly implicated in hypokalemia, hypocalcaemia and dysrrthymias.
We report a case of 60 year old patient, suffering from rectal carcinoma for a period of one year with confirmed hypokalemia,
hypocalcaemia and hyponatremia. Magnesium supplementation corrected the underlying multiple electrolyte disturbances in the
patient thus, establishing a positive correlation of magnesium with sodium, potassium and calcium. 相似文献

Sialic acid, the end moieties of the carbohydrate chains are biologically important and essential for functions of glycoconjugates
and are reported to be altered in cancer patients. Two hundred and twenty five breast cancer (BC) patients, 100 patients with
benign breast disease (BBD) and 100 healthy females (controls) were enrolled for the study. Eight hundred and twenty four
follow-up samples of 225 breast carcinoma patients were also evaluated. The association of sialic acid forms, sialyltransferase
and α-2–6 sialoproteins levels with presence and extent as well as prognosis of breast carcinoma was studied. Serum sialic
acid forms and sialyltransferase revealed significantly elevated levels among untreated breast cancer patients as compared
to the controls, patients with BBD as well as cancer patients in remission. Non-responders showed comparable levels of the
markers with those found in breast cancer patients at the time of diagnosis. Higher levels of sialic acid forms at diagnosis
were associated with poor prognosis. A positive correlation between serum levels of different forms of sialic acids and extent
of malignant disease was observed. The changes in serum proteins with terminal α-2–6 sialic acid correlated well with alterations
in the levels of sialic acid forms and sialyltransferase. Malignant tissues showed elevated levels of sialic acid and sialyltransferase
as compared to surrounding normal tissues.
The results suggested potential utility of these markers in evaluation of clinical outcome. 相似文献

Cripto-1 (CR-1) is an oncofetal protein with its role as a key factor in early process of carcinoma has been evaluated in cases of various cancers. However, very few studies have reported its role in oral cancer, which is the sixth most common cancer around the world, particularly with high prevalence in developing countries. Oral squamous cell carcinoma (OSCC) is the most predominant (90%) of all the histological types of oral cancer. Late detection, associated with increased morbidity and mortality, is mainly attributed to non-availability of a suitable biomarker for the disease. In the present pilot study, we have evaluated the role of soluble CR-1, in serum as a potential tumor marker for OSCC. CR-1 was estimated using sandwich ELISA in serum samples of 50 biopsy proven OSCC patients (pre and post treatment) along with age and gender matched healthy controls. Immunohistochemistry was also done in corresponding tumor tissue sections to check the expression of CR-1. Pre-treatment CR-1 was found to be 2.25-fold higher in serum of OSCC patients as compared to control (p < 0.0001***), which was reduced to 1.6 folds post treatment (p = 0.0006***). CR-1 levels were comparatively higher in early stage of disease. Upon IHC 80% of the cases were found to be positive for CR-1. This study provides evidence that serum levels of CR-1 are elevated in patients of Oral Squamous Cell Carcinoma, which decrease post treatment. Also, the association of expression of protein with tumor progression predicts CR-1 as a molecule that can be further evaluated as a potential tumor maker in OSCC. 相似文献

Reactive oxygen species (ROS) cause damage to the DNA producing mutations and formation of tumours such as carcinoma of breast. Tumour cells are known to produce ROS at a greater pace than the non-transformed cells. The increased production of reactive oxygen species causes oxidative stress leading to cell proliferation and hence increased inflammatory conditions. The present study was aimed to investigate the role of oxidative stress in the pathogenesis of breast cancer. Females suffering from breast cancer had significantly decreased Superoxide dismutase (SOD) and reduced glutathione (GSH) levels in comparison to normal females. The compromised antioxidant defence system produces the oxidative stress which in turn creates the inflammatory response shown by concomitant increased adenosine deaminase (ADA) activity in female patients. ADA diminishes the protective molecule adenosine. There were significant variations (p < 0.01) in ADA activity with different clinical stages (stage 1–4) of breast cancer suggesting thereby that estimation of ADA activity can be used as a diagnostic tool to detect the stage of cancer along with cytological studies. Mastectomy was performed and post-operatively serum SOD and ADA activity and plasma GSH levels were estimated. There was a statistically significant increase in activity of SOD and levels of GSH while serum ADA activity decreased significantly, suggesting thereby that oxidative stress is responsible for increased cell proliferation and hence the inflammatory conditions in CA breast that got ameliorated post-operatively. 相似文献

Serum Adenosine Deaminase (ADA) activity was studied in 20 control cases and 32 patients with carcinoma breast. In control group the ADA activity ranged from 13–94 IU/L with a mean of 43.75±21.55 IU/L while in patients of carcinoma breast it was 16–95 IU/L with a mean of 47.46±22.54 IU/L, but these values were not statistically different. The ADA activity was also compared with other parameters in patients of carcinoma breast but the difference was not statistically significant in the various parameters like duration of disease, menopausal status, tumor size, hemoglobin level, total leucocyte count, absolute lymphocyte count, total serum proteins, serum albumin, histological grade of tumor and lymphocytic infiltration. The only significant difference in ADA activity was when N1 status of lymph node was compared with N2 status of lymph node. 相似文献

Prostate Specific Antigen (PSA) has emerged as the most applicable and important tumor marker for carcinoma prostate. In the
present study PSA was determined in serum of healthy subjects, patients of benign prostate hypertrophy (BPH) and Carcinoma
Prostate (Ca−P) to evaluate its diagnostic efficiency in day to day management of prostate cancer patients and in differentiating
patients of early prostate cancer from those with BPH. Receiver operating characteristic curve (ROC) revealed 2 ng/ml and
10 ng/ml cut off serum PSA level for BPH and untreated carcinoma prostate patients (Ca−P). An extremely significant increase
(P<0.0001) was observed in mean PSA concentration in BPH patients and adenocarcinoma prostate patients when compared to healthy
males. Clinical relevance of PSA was highlighted by a case study of cancer patient prior to any therapy till death. 相似文献

There are numerous growing evidences of resemblance between carcinomas of the breast and prostate. A total of 45 cases of
these two hormone-dependent cancers along with appropriate controls were subjected for status of epidermal growth factor receptors
as well as serum lipid profile. Paraffin embedded tissue sections from aforesald tumours were analysed by immunohistochemical
staining for epidermal growth factor receptor (EGF-R), c-erbB-2 oncoprotein, estrogen receptor (ER) and progesterone receptor
(PgR). Sera from same individuals were studied for serum lipid profile analysis. The study revealed that immunoexpression
of all receptor proteins (EGF-R). c-erbB-2 was significantly higher in breast carcinoma. In addition, mean levels of triglycerides,
total cholesterol, LDL-cholesterol were found to be significantly elevated while the level of HDL-cholesterol was observed
to be lower among patients with breast cancer as compared to matched controls. Further, ER-positive breast cancer cases have
significantly higher mean level of HDL-cholesterol when compared with ER-negative breast cancer patients. Contrary to this,
no alteration in different serum lipid fractions was noticed among the patients with prostate cancer. However, a positive
relationship was noticed between immunoexpressions of EGF-R and c-erbB-2 in prostate cancer. 相似文献

Tuberculosis has, in a short span of time, become a major health problem in the third world or developing countries like India.
In view of this, a retrospective study was conducted to study Adenosine deaminase activity in serum and pleural fluid in patients
affected with Pulmonary Tuberculosis and other common non-tubercular chronic respiratory diseases. The study was carried out
on 100 patients suffering from various pulmonary disorders, between January 2002 and August 2002. Thirty-five normal healthy
individuals were included as control subjects. ADA estimation was done by sensitive colorimetric method. The study revealed
that the serum ADA activity was higher in patients of tuberculous pulmonary and pleural diseases and non-tuberculous pulmonary
diseases than in control subjects. The mean serum ADA activity in the patients’ group was 35.5±6.93 u/l as compared to 16.20±2.85
u/l in control group, showing a highly significant (P≪0.001) difference. ADA activity was highest in tuberculous pleuropulmonary
diseases. The pleural fluid ADA activity was higher in pyogenic pleural effusion than in tuberculous pleural effusion. 相似文献

Appropriate therapeutic measures can improve the life expectancy of patients with ovarian malignancy. There has been a pressing
need for serodiagnostic assays to enable, the close patient monitoring. Cancer Antigen 125 (CA125) has been described as a
useful marker in patient monitoring for ovarian malignancy. Keeping this in view, the present study was planned. 40 consecutive
female patients of ovarian carcinoma (mean age 52.4±10.7 years) were selected for serum CA125 analysis during the period of
year 1995–2001. The tumour marker concentration was compared with histologic types of ovarian tumour and the FIGO staging
of the disease. 25 healthy females (mean age 35.2–10.4 years) served as control. Mean serum CA125 concentrations in patients
with papillary serous adenocarcinoma(Mean±%CV 1571±121.5 U/ml) was much higher than patients with mucinous adenocarcinoma(775±78U/ml).
Mean serum CA125 concentration in endometrioid carcinoma was very high(2853±136 U/ml). The patient with clear cell carcinoma
however had shown moderate increase(60 U/ml). No correlation was found between serum CA125 concentration and the FIGO staging
of disease.
Quantitation of CA125 was most helpful in monitoring the response of treatment and followup of the patients after completion
of their treatment. Posttherapeutically its concentration showed more than 50% reduction in almost all (91.4%) patients (P<0.001).
Importantly these patients had also shown significant regression of the disease clinically and radiologically. 8.6% of patients
had shown static or increase in serum CA125 concentration which was associated with either clinically static or progressive
disease. Recurrence of the disease was noted in patients who had shown increase in serum CA125 concentration (biochemical
recurrence) in the followup
However, in our test population biochemical recurrence(increase in serum marker concentration) preceded the clinical or radiological
recurrence by an average of 6.5 months.
Kaplan meier survival analysis for evaluation of overall survival in our test subjects showed an overall survival of 32% at
one year and median survival of 9 months with confidence interval of 6.34 to 11.66. We conclude that serum CA125 is a useful
marker for monitoring the treatment and predicting an early recurrence of the disease in ovarian carcinoma patients. A study
in larger number of patients is needed to define its exact role in the management of the carcinoma ovary. 相似文献

Now a days measurement of molecular forms of PSA has gained importance in clinical practice. Several studies have demonstrated
the production of PSA in female tissues, such as breast. The present piece of work has been undertaken with an objective to
estimate the relative proportion of the molecular forms of PSA in serum along with serum testosterone in benign and malignant
breast tumor cases and to analyze their association with the severity of the disease process 34 malignant and 26 benign breast
disease cases along with 33 healthy controls of same age group were enrolled in this study for evaluation. Serum testosterone
was measured by ELISA, whereas serum total PSA (TPSA) and free PSA (FPSA) were estimated by electrochemiluminescence immunoassay.
A significant rise of fasting plasma glucose along with prominent dyslipidemia was observed in breast tumor cases. Marked
rise in serum testosterone as well as TPSA and FPSA was documented in both benign and malignant breast tumor cases. Serum
testosterone revealed a significant positive association with both TPSA and FPSA pointing towards an etiological association
between them. However, surgical removal of tumor mass resulted in a marked decline of presurgical value of both TPSA and FPSA
with a non-significant fall in serum testosterone revealing tumor tissue as the source of FPSA and TPSA. Thus, estimation
of PSA provides prognostic information that may assist in future treatment. 相似文献

This study was conducted to investigate the diagnostic performance characteristics of prostate specific antigen (PSA) by comparing
serum PSA value with histological findings in patients suspevted of having prostate cancer in Aminu Kano Teaching Hospital.
Nigeria. Clinical and Laboratory records were examined and collated for serum PSA values, together with histological findings
of biopsy specimen, clinical diagnosis, age of patients, and mode of presentation. The serum PSA values were determined by
ELECSYS 1010 autoanalysers Roche, Germany based on electrochemiluminescence immunoassay technique. The results show that serum
PSA values increase with age in the assymptomatic non-cancer patients who came for medical check up but were within normal
limit. In prostatic disease conditions PSA values were raised in benign prostatic hyperplasia 35.957± 4.0315ng/ml, in undifferentiated
carcinoma 56.22±4.295ng/ml and adenocarcinoma >100ng/ml as compared to the normal range (0–4ng/ml). These cases were confirmed
by histological diagnosis. It is concluded that PSA evaluations is a sensitive marker for prostate cancer but because of various
other conditions that affect serum PSA concentration, other methods of investigations such as Digital Rectal examination,
Trans Urethral Ultra-Sonography and histological examination should be combined to confirm diagnosis. Prognosis of patients
will be better if early diagnosis is made. 相似文献
