The analysis of biochemical parameters in 162 patients with various neoplastic disorders along with 50 normal subjects showed significant rise in serum alkaline phosphatase and lactate dehydrogenase as compared to normal subjects. 21 patients with other monoclonal gammopathies which include infection and immunological diseases were also studied. Parameters such as serum calcium, uric acid, total protein, albumin and globulin were also analyzed in 42 (26%) cases of multiple myeloma, 27 (17%) cases of gastro-intestinal malignancies, 22 (14%) cases of urogenital malignancies, 11 (6%) cases of carcinoma breast, 4 (2%) cases of bone tumors, 21 (12%) cases of other monoclonal gammopathies, including 7 (4%) cases of infection and 14 (8%) cases of immunological diseases. The results indicate use of enzymes alkaline phosphatase and lactate dehydrogenase in neoplastic disorders. 相似文献

Colostrum, the mammary secretion during first 2–4 days of lactation, provides all the essential components of nutrition and
passive immunity required by the newborn. Pregnancy induced hypertension (PIH), glucose intolerance and anaemia are common
medical complications observed during pregnancy in Indian women and their effects were studied on the composition of colostrum
collected within 24 hours of delivery from lactating women included in the study. PIH during pregnancy significantly decreased
colostrum IgA and total proteins, but showed a significant increase in K+ levels, where as women with glucose intolerance showed a significant decrease in total lipids and lactose and an increase
in Na+ levels in colostrum compared to normal controls. The group with anaemia also showed a significant decrease in colostrum IgA
and total protein levels when compared with the control group. Awareness about the changes that occur in the composition of
colostrum during complicated pregnancies can be an important and useful tool for preventive and protective paediatrics. 相似文献

Nineteen subjects of non-insulin dependent diabetes mellitus (NIDDM) between the age group of 30–60 yrs were studied to see
the effect of specific yoga asanas on fasting and postprandial blood glucose (FBG, PPG), serum malondialdehyde (MDA) and glycosylated
hemoglobin (HbA1) in addition to drug treatment and diet control. The duration of diabetes ranged from 1–10 years. Patients with renal, cardiac
and proliferative retinal diseases were excluded from the study. The same patients served as their own control. Subjects were
called in the morning to the cardio-respiratory laboratory and were given training by a yoga expert. Yoga asanas included
Suryanamskar, Tadasan, TriKonasan, Padmasan, Pranayam, Paschimottanasan, Ardhmatsyendrasan, Pavanmukthasan, Sarpasan and Shavasan.
The asanas were done every day for 40 days for 30–40 min. FBG, PPG, serum MDA and HbA1 were estimated before and after 40 days of yoga asanas regimen. Significant reduction was seen in FBG from 220 mg/dl to 162
mg/dl, PPG from 311 mg/dl to 255 mg/dl, MDA from 6 nmol/l to 3 nmol/l and HbA1, from 8.8% to 6.4%. Subjects felt better and were relieved of their stresses and had an improvement in their day to day performance.
The decrease was statistically significant (p<0.0001 for FBG and PPG, p<0.001 for MDA and for HbA1). 相似文献

It has been shown (Lawrence, S. (2001). Online or invisible? Nature, 411, 521) that journal articles which have been posted without charge on the internet are more heavily cited than those which have not been. Using data from the NASA Astrophysics Data System (ads.harvard.edu) and from the ArXiv e-print archive at Cornell University (arXiv.org) we examine the causes of this effect. 相似文献

Our study aimed at comparing lead and zinc protoporphyrin (ZPP) levels in capillary and venous blood samples in a small population
and to employ an easier method of sample collection for a major screening program in school children in major Indian cities.
An awareness program on lead and its effects was conducted in two different schools. A total of thirty urban school children
from South India, with an age group between 4–12 years consented for dual blood sampling and reported for the study. Venous
and capillary blood samples were obtained simultaneously. Blood lead and zinc protoporphyrin (ZPP) levels were estimated using
ESA Lead Analyzer and Haematofluorometer respectively. A significant correlation between capillary and venous ZPP (r=0.98)
and lead (r=0.99) was observed. Rank sum test showed that there is no statistically significant difference between capillary
and venous ZPP (P=0.891) and lead (P=0.672) values. This pilot study recommends that screening for lead may be done using
capillary blood samples since significant correlation is observed between capillary and venous blood measurements. Obtaining
samples using this mode is a non-invasive, less expensive, quick and easy method in children. Appropriately performed capillary
sampling may be considered as an acceptable alternative to venipuncture for screening of blood for lead poisoning both in
children and adults. 相似文献

The present study was undertaken in 100 subjects, 30 diabetics without complication (group I), 40 diabetics with retinopathy
(group II) and 30 non diabetic as normal control group (group III). Blood sugar levels, magnesium, cholesterol and triglyceride
were analyzed from plasma and serum. The results were correlated with degree of diabetic control from the levels of glycosylated
hemoglobin. Serum magnesium levels in group II were found to be significantly lowered than in group I. There was also significant
difference in magnesium levels of group I and group III. We found a significant correlation between the glycosylated hemoglobin
and magnesium levels in our study.
The results also indicate that the patients with diabetic retinopathy showed significant rise in serum cholesterol and triglyceride.
Probably hypomagnesemia and increased serum cholesterol and triglyceride levels are responsible for microvascular changes
in diabetes leading to retinopathy. The purpose of this study was thus to gather information about the degree of control of
diabetes and magnesium status. 相似文献

The problem factorizing (separating) the transfer function of a given SISO 3-D discrete system, ie of a system depending on three independent variables, is considered. The 3-D system is assumed to be available in its transfer function representation, which is converted to a canonical state-space model by a simple inspection procedure. Then applying state-feedback to this canonical model we choose the feedback matrix gain (under certain conditions) such that the transfer function of the closed-loop system has the desireed factorized form, ie a product of three 1-D transfer functions each one being dependent on a single variable. The method is illustrated by a nontrivial numerical example. 相似文献
