Serum and urine samples from 513 patients clinically suspected of monoclonal gammopathies over a period of five years (1992–97) were subjected to various immunological procedures viz, electrophoresis, immunoelectrophoresis and immunoglobulin estimations. Laboratory investigations confirmed gammopathies in 10.33%. It was observed that overall age of incidence for monoclonal gammopathies in both sexes was between 42–72 years with a male to female ratio of 1.4∶1. Predominant paraprotein detected was IgG type (75.47%) followed by IgA (16.98%) and Bence Jones proteins (7.55%). Amongst positive patients, 64.16% were having kappa (k) type light chains and 35.84% lambda (δ) type light chains. 69.39% patients with serum M component (IgG and IgA) had Bence Jones proteinuria. Densitometric scanning revealed that majority of IgG type paraprotein was found in the slow gamma globulin region and majority of IgA type paraprotein was found equally distributed between beta and fast gamma globulin regions. Both types had decreased albumin and alpha-2-globulin concentrations as compared to normal controls. Immunoglobulin levels in patients with paraprotein had very high levels of serum IgG (6467.0 mg%) and IgA (2714.0 mg%) in respective types of monoclonal gammopathies; the rest of immunoglobulin classes were either at normal or decreased levels.  相似文献

We have studied the expression of lactate dehydrogenase and its isoforms in gall bladder cancer, cholelithiasis and chronic cholecystitis. Quantitative and qualitative assays of lactate dehydrogenase and its various isoforms were carried out in the blood sera of patients and healthy controls along with parallel estimation of various liver function test enzymes. Statistical analysis was done using the software Graph Pad Prism. Significantly high expression of lactate dehydrogenase along with alkaline phosphatase and total bilirubin (P ≤ 0.05) was observed in all the three clinical conditions as compared to controls. LDH showed an increasing trend from stage I to stage IV of GBC indicating a significant positive association with the disease progression. The levels of LDH 3 and 4 isoforms appeared significantly more elevated in GBC than cholelithiasis or chronic cholecystitis. We suggest that a careful estimation of total LDH and its isoforms 3 and 4 alone or along with alkaline phosphatase and total bilirubin during different clinical stages, like chronic cholecystitis, cholelithiasis and GBC, may prove to be a potentially useful biomarker in the prognostic management of gall bladder diseases, specifically GBC.  相似文献

Circadian rhythm of serum glucose, pyruvate, lactate and lactate dehydrogenase (LDH) was studied in normal healthy young volunteers at the onset (I Group, 7 cases) and peak (II Group, 8 cases) of winters in India with highly varied temperature. There was a significant difference, in the circadian rhythm of glucose, pyruvate and lactate dehydrogenase (LDH) of the two groups. A clockwise shift was observed in acrophase except in serum lactate, which is related to the energy demand in association with time qualified changes in diurnal activity of the individuals and change in photoperiod.  相似文献

L-asparaginase isolated in our laboratory fromAeromonas has been found to be antileukaemic. In the present study changes in the levels of serum enzymes in leukaemic mice and under treatment withAeromonas L-asparaginase has been compared. A significant increase in the levels of serum lactate dehydrogenase with tumour growth and a decrease during therapy was observed. A significant decrease in alanine transaminase activity during tumour growth and an increase during treatment was noticed. Increased levels of aspartate transaminase and alkaline phosphatase was observed during enzyme therapy. Total acid phosphatase was found to be increased during tumour growth and decreased considerably during treatment.  相似文献

Apart from the biochemical parameters routinely used like Vanillyl Mandellic Acid for the patients with neuroblastoma the parameters like neuron specific enolase, ferritin, lactate dehydrogenase, gamma glutamyl transferase were also studied to assess the utility in diagnosing the patients with neuroblastoma. The study involved 40 healthy ambulatory subjects and 30 untreated cases of histologically proved neuroblastoma referred to the Tata Memorial Hospital for further management and treatment. The urinary Vanillyl Mandellic Acid levels and the serum levels of neuron specific enolase, ferritin, lactate dehydrogenase had increased significantly, p<0.001 whereas the gamma glutamyl transferase had decreased significantly p<0.001, as compared to the normal. Serum neuron specific enolase, ferritin, lactate dehydrogenase alongwith urinary Vanillyl Mandellic Acid could be of help in diagnosing the patients with neuroblastoma.  相似文献

In the present study, monoclonal gammapathy was identified in a total of 245 patients of plasma cell dyscrasias during period of 1987 to 2000. The monoclonal band was identified in serum by agar gel electrophoresis in all the cases and in urine in a few cases. Characterization of paraprotein (monoclonal immunoglobulin class and light chain type) was carried out by employing immunoelectrophoresis and/or immunofixation electrophoresis using heavy chain specific gamma, alpha, mu, delta and epsilon and light chain specific kappa (K), lambda (λ) antisera. Serum immunoglobulins Ig G, Ig A, and Ig M were estimated by immunoturbidometry. Serum urea, creatinine, uric acid, alkaline phosphatase, total proteins, albumin, calcium and phosphorus were estimated by using routine biochemical methods. Among the 245 cases, 73.1% monoclonal gammapathies were of secretory type and 7.3% were non-secretory. Monoclonal gammapathies were associated with 80.4% of multiple myeloma, 8.9% of solitary plasmacytoma, 4.1% of extra-medullary plasmacytoma, 3.3% of lymphoma and 2.9% of plasma cell leukemia. Classification of secretory monoclonal immunoglobulin revealed monoclonal immunoglobulin Ig G in 74%, Ig A 15% and Ig M in 2.9% cases.  相似文献

The serum and hepatic enzymes of rats were studied after exposed to country made liquor (CML) along with two chelating agents (glutathione and Selenium). There was a significant increase in several serum enzyme levels (viz., aspartate transaminase, alanine transaminase, alkaline phosphatase, sorbitol dehydrogenase, glutamate dehydrogenase, bilirubin) and decrease in various hepatic enzymes (Succinic dehydrogenase, Glucose 6-phosphatase, 5'Nucleotiease, Acid phosphatase, Acid ribonuclease, Cytochrome P-450) due to repeated administration of CML (2ml/100g of body weight). Results of this study revealed that the GSH and Se could give a significant protective action in serum and hepatic enzymes of CML exposed rats.  相似文献

Bacopa monniera, a medicinal plant distributed throughout India. Cytosine arabinoside (1-β-arabinofuranosylcytosine; Ara-C) is the most important antimetabolite chemotherapeutic drug used for acute leukemia. In this study we examined the chemoprotective property of an ethanolic extract of Bacopa monniera on biochemical changes in chick embryo. CA caused biochemical changes in a concentration and time dependent manner in amniotic fluid, liver and heart tissues. Ethanolic extract of BM given to chick embryo at doses of 2, 4, 6 mg per egg. There is significant decrease in biochemical levels of glucose, protein, urea, uric acid, creatinine and inorganic phosphorus. Enzymatic activities of alkaline phosphatase, lactate dehydrogenase, serum glutamate oxaloacetate transaminase, serum glutamate pyruvate transaminase and malatedehydrogenase were also decreased with dose dependent manner in amniotic fluid, liver and heart tissues.  相似文献

A clinical study was carried out on an antiprogestin, a synthetic steroid, 17 Hyroxy-11 β-(4-dimethyl amino-phenyl-1)—17 (Prop-1-ynyl-estra—4, 9, dien-3-one) for the termination of pregnancies in female subjects within 14 days of missed menstrual period and with positive urine pregnancy test (Gravindex Test). The compound was tested for its efficacy as an abortifacient and its acceptance by human subjects was assessed by measuring various biochemical parameters before and after introduction of the drug. The parameters measured in the subjects included, fasting blood sugar, blood urea, SGOT, SGPT, serum alkaline phosphatase, serum bilirubin, serum creatinine, serum proteins, A/G ratio and serum Na+, K+. Statistically insignificant variation was noted in all the parameters studied. This clearly shows that the drug is very well accepted by human subjects. 70% of the subjects tested in the pilot study aborted within 4 days of introduction of the drug. Overall, 90% of the subjects tested aborted as a result of introduction of the drug.  相似文献

The microbicidal capacity of polymorphonuclear (PMN) leukocytes of normal human subjects was evaluated by estimating the release of lysosomal enzymes from normal cells and cells rendered incapable of ingesting particles by treatment with cytochalasin B, on exposure to a particulate stimulus-serum treated zymosan (STZ). The release of lysosomal enzymes namely beta-glucuronidase, lysozyme, acid phosphatase, alkaline phosphatase was found to be 16.28%, 27.84%, 20.54%, 15.40% respectively. The cells rendered incapable of ingesting particles showed enhanced response. The percentage release of beta-glucuronidase, lysozyme, acid and alkaline phosphatase was increased to 20.58%, 37.95%, 25.87% and 33.04% respectively. This type of response in cytochalasin B treated PMN leukocytes is due to the conversion of these cells into “secretory cells”, which release lysosomal enzymes outside the cell, by the process of reverse endocytosis.  相似文献

The indigenous Khasis inhabit different geographical and climatic locations of Meghalaya. In this study, we intended to find out whether habitation in moderately high altitude place has any effect on the lipid and liver profile amongst the aged Khasis. The level of various serum parameters under lipid and liver profile were analyzed and compared from aged (65–70 years) male Khasi residents of moderately high (Shillong city) and low (Byrnihat) altitude places. Results obtained from the lipid profile data show decreased total serum cholesterol (29%), triglyceride (27%) and LDL-cholesterol (42%) level in the old Khasis of Shillong compared to Byrnihat. Furthermore, the alkaline phosphatase activity was significantly raised (47%) in the old Khasis from Shillong as against Byrnihat. The decreased level of total cholesterol, triglyceride and LDL-cholesterol in old Khasis from Shillong may be due to living and acclimatization in high altitude with low annual temperature. Moderately high elevation could have acted as a stressor, thereby reducing the level of serum cholesterol, triglyceride and LDL-cholesterol, which may put them at a lower risk of cardiovascular diseases. In comparison, old residents of Byrnihat with high cholesterol, triglyceride and LDL-cholesterol levels may elevate their risk of coronary complications. The raised alkaline phosphatase activity amongst the old Khasis of Shillong could be due to increased bone and/or intestinal turnover as a result of living in high altitude, which, however, may elevate the risk of osteoporosis. Taken together, we conclude that low cholesterol, triglyceride and LDL-cholesterol levels, accompanied with high alkaline phosphatase activity amongst the old Khasis of Shillong, could be due to the influence of high altitude and mild climatic conditions that prevails.  相似文献

Psychiatric disorders especially depression are associated with a variety of changes in immunity parameters. In this work, an attempt was carried out to make estimation about the correlation between immunity and depression through the measuring of IgG, IgA, and IgM and complements (C3 and C4) levels in the serum of patients and comparing them with the corresponding levels of healthy control group. The results showed a significant increase in serum level of C3, C4, cortisol, IgG and no significant differences were noticed in the level of IgA and IgM in the depressed patients group as compared with control group. A slight positive correlation was observed between cortisol versus IgG in depressed patients that is not found in normal subjects. Thus in depression, human body defenses psychologically and sometimes this defense transformed into immunological resistance that is expressed as different measurable changes in immunological parameters.  相似文献

The continuous use of synthetic hormones as contraceptive pill or hormonal replacement therapy among women is increasing day by day. The widespread use of different formulations as oral contraceptives by women throughout their reproductive cycle has given rise to a serious concern for studying the effects of oral contraceptives on enzymatic profile and DNA damage in peripheral blood lymphocytes among users. The present study was carried out on women taking oral contraceptives. The study was based on the questionnaire having the information of reproductive history, fasting, age, health, nature of menstrual cycle, bleeding and other disease. The profile of the blood serum enzymes i.e. alkaline phosphatase (ALP), gamma glutamyl transferase (GGT), lactate dehydrogenase (LDH), aminotransferases (SGOT and SGPT), serum proteins (albumin and globulin) and DNA damage in lymphocytes was studied among users and non-users. The results of the present study suggest that OCs not only effects enzymatic activity but also results in DNA damage that may vary with the duration of using oral contraceptives. A significant increase in LDH, GGT, SGPT, SGOT, globulin and decrease in ALP as well as albumin was found among users as compared to non-users. The observed DNA damage was more in users as compared to non-users. Hormonal contraceptives seem to exert DNA damage and also have significant effects on blood serum enzymes.  相似文献

The influence of Crataeva nurvala bark decoction was studied in calcium oxalate stone forming rats, in relation to oxalate metabolism in liver. The activities of the major oxalate synthesizing enzymes in liver namely, glycollate oxidase (GAO) and lactate dehydrogenase (LDH) were significantly increased in the calculogenic group. Bark decoction treatment lowered the liver GAO activity considerably. Transport ATPases (Na+, K+ and Ca2+-ATPases) and alkaline phosphatase were enhanced in rats fed calculi producing diet, while the activities of acid phosphatase, inorganic pyrophosphatase and aminotransferases were slightly reduced. Bark decoction administration produced a marginal decrease in Na+, K+-ATPase and increase in aspartate aminotransferase activities, without significantly altering other enzyme activities. The decrease in liver GAO activity seen during bark decoction treatment, with concomitant decrease in kidney oxalate level, may prove beneficial as a prophylactic measure in preventing stone recurrence.  相似文献

Serum alkaline phosphatase (ALP) (EC 3.1.3.1), 5′nucleotidase (5′NT) (EC 3.1.3.5), aldolase (ALD) (EC 4.1.2.13) and sorbitol dehydrogenase (SDH) (EC 1.1.1.14) were estimated in infective hepatitis, alcoholic hepatitis, chronic active hepatitis, obstructive jaundice, cirrhosis of liver and amoebic liver abscess. It was observed that serum ALP and 5′NT were significantly increased in all cases of chronic active hepatitis and obstructive hepatic disease. However, the elevation observed in the latter was much higher than the former. Serum SDH and ALD levels were elevated in all cases of infective hepatitis, studied though increase in the former was much higher than the latter, suggesting its significance in the diagnostic confirmation of this disease. Results presented suggest 5′NT and SDH as more reliable diagnostic test compared to ALP and ALD for obstructive jaundice and infective hepatitis respectively.  相似文献

The present study conducted on twenty-five uncomplicated cases of acute myocardial infarction diagnosed by clinical and electrocardiographic findings indicated significantly increased level of cardiac Troponin-T and increased activities of the enzymes total creatine kinase, creatine kinase-MB, aspartate transaminase and lactate dehydrogenase as compared to the twenty-five healthy control subjects. The level of cardiac Troponin-T and the activities of the enzymes total creatine kinase, creatine kinase-MB, aspartate transaminase and lactate dehydrogenase was found to be higher in “Q” wave myocardial infarction patients as compared to the non-“Q” wave and the controls. Since cardiac Troponin-T has been shown to increase in unstable angina and renal failure without cardiac disease and creatine kinase-MB activity has been found to be normal in patients with unstable angina and increase very slightly in patients with renal failure, it was concluded that a combination of cardiac Troponin-T and creatine kinase-MB activity was sufficient for the early diagnosis of acute myocardial infarction.  相似文献

This paper presents certain simple procedures for assessing the most common types of interference, due to haemolysis, icterus or lipaemic serum in 19 routine Clinical Chemistry tests and suggests steps to overcome the problem in some tests. A change in the measured concentration, to be analytically significant, had to exceed 2.8 X % coefficient of variation (cv) of the intra-assay analytical variation of each assay. Haemolysis caused interference in 10 of the 19 assays investigated. A haemolysate haemoglobin concentration of 0.29 g/dl, visible to the eye, caused an analytically significant increase in creatinine kinase MB subunit (CKMB), lactate dehydrogenase (LDH), total protein, triglyceride, uric acid and urea, and a significant decrease in alkaline phosphatase (ALP), and total bilirubin. A higher concentration of haemoglobin (0.68 g/ dl) caused an additional significant increase in CK, and a decrease in direct bilirubin. Addition of bilirubin caused interference in all the peroxidase linked reactions as well as in the creatinine assay. At a serum concentration of 5.2 mg/dl it caused a decrease in creatinine, glucose, triglyceride and uric acid. At a higher concentration (15.9 mg/dl) it also decreased cholesterol. Lipaemia interference affected the least number of assays. An added triglyceride of 537–561 mg/dl caused an increase in glucose, uric acid, and amylase. At a level of 1122 mg/dl it also increased CKMB, and at a value of 2244 mg/dl it increased total and direct bilirubin. At the highest levels of haemolysis and lipaemia, the serum glutamate oxaloacetate transaminase (GOT) and giutamate pyruvate transaminase (GPT) gave erratic results. Overall uric acid and CKMB were the analytes most susceptible to interference, while serum caicium and phosphate did not suffer from any. The interference depends on the exact assay conditions used and the susceptibility of each individual laboratory's tests should be determined by them. The reasons for the interferences described are discussed.  相似文献

Tumor lysis syndrome has been observed in patients with malignancies with high cellular burden and high cell turnover, tumor sensitive to therapy, especially after initiating medical treatment. It very rarely occurs spontaneously. The case described here is of 6 months male infant who presented with fever since 1 month and loose stools associated with blood since 15 days. The laboratory investigations showed lactate dehydrogenase (LDH) of 6,192 IU/L and serum uric acid 18.2 mg/dl along with pancytopenia. The infant presented with electrolyte abnormalities and renal failure.  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

The biological activity of the mineralocorticoid antagonist, spironolactone depend upon its metabolism. In this study the effect of diuretic drug compound spironolactone on the acid and alkaline phosphatase in the testes of albino rat. The drug spironolactone was administered orally daily for 7th, 14th and 21st days at the dose of 100 mg/kg body weight. Among them, the side effects of drug are that the degradation of alkaline phosphatase in the testes; while acid phosphatase increased significantly may be due to 7a-thiospironolactone is a tissue metabolite of spironolactone and may contribute to the testicular enzymes, therapeutic actions and some other side effects. It is suggested that the decrease and increase of alkaline and acid phosphatase in the testes of albino rat are the due to the side effects of spironolactone drug compound.  相似文献
