Abstract
INTRODUCTION Respiratory infections and wheeze have a considerable impact on the health of young children and consume significant healthcare resources. We aimed to evaluate the effect of environmental factors on respiratory infections and symptoms in early childhood. METHODS Environmental risk factors including: daycare attendance; breastfeeding; siblings; damp within the home; environmental tobacco smoke (ETS); child's bedroom flooring; animal exposure; road traffic density around child's home; and solid fuel pollution within home were assessed in children recruited to the GO-CHILD multicentre prospective birth cohort study. Follow-up information on respiratory infections (bronchiolitis, pneumonia, otitis media and cold or flu), wheeze and cough symptoms, healthcare utilisation and medication prescription was collected by postal questionnaires at 12 and 24 months. Log binomial and ordered logistic regression models were fitted to the data. RESULTS Follow-up was obtained on 1344 children. Daycare was associated with increased odds of pneumonia (odds ratio [OR] = 2.39, 95% confidence interval [CI]: 1.04-5.49), bronchiolitis (OR = 1.40, 1.02-1.90), otitis media (OR = 1.68, 1.32-2.14) and emergency department attendance for wheeze (RR = 1.81, 1.17-2.80). Breastfeeding beyond 6 months was associated with a reduced odds of bronchiolitis (OR = 0.55, 0.39-0.77) and otitis media (OR = 0.75, 0.59-0.99). Siblings at home was associated with an increased odds of bronchiolitis (OR = 1.65, 1.18-2.32) and risk of reliever inhaler prescription (RR = 1.37, 1.02-1.85). Visible damp was associated with an increased odds of wheeze (OR = 1.85, 1.11-3.19), and risk of reliever inhaler (RR = 1.73, 1.04-2.89) and inhaled corticosteroid prescription (RR = 2.61, 1.03-6.59). ETS exposure was associated with an increased odds of primary care attendance for cough or wheeze (OR = 1.52, 1.11-2.08). Dense traffic around the child's home was associated with an increased odds of bronchiolitis (OR = 1.32, 1.08-2.29). CONCLUSION Environmental factors likely influence the wide variation in infection frequency and symptoms observed in early childhood. Larger population studies are necessary to further inform and guide public health policy to decrease the burden of respiratory infections and wheeze in young children.

Abstract
BACKGROUND Mannose-binding lectin (MBL) is an important component of the innate immune system. Polymorphisms in the MBL2 gene and promoter region are directly associated with MBL-deficiency. We sought to determine the association between MBL genotype on the frequency of common childhood respiratory infections, respiratory symptoms, and atopic outcomes in early childhood. METHODS MBL2 gene variants were analyzed in newborns recruited to the GO-CHILD multicenter prospective cohort study. Follow-up for respiratory infection and atopy diagnoses and symptoms, healthcare utilization, and medication prescription were conducted by postal questionnaires at 12 and 24 months. RESULTS Genotyping and follow-up were completed in 1004 children. Genotypes associated with MBL-deficiency were associated with an increased risk of bronchiolitis (relative risk [RR] 1.95, 95% confidence interval [CI] 1.33-2.85) and pneumonia (RR 2.46, 95% CI 1.16-5.22). MBL-deficient genotypes were associated with an increased risk of wheeze with shortness of breath episodes (RR 1.22, 95% CI 1.04-1.43), emergency department attendance (RR 1.90 95% CI 1.13-3.19), and hospital admission (RR 2.01, 95% CI 1.04-3.89) for wheeze. MBL-deficient genotypes were associated with a reduced risk of developing atopic dermatitis (RR 0.72, 95% CI 0.53-0.98). CONCLUSION The positive association between MBL-deficient genotypes and bronchiolitis and pneumonia, as well as a severe wheeze phenotype in some young children, supports the hypothesis that MBL is an important component of innate immunity in the vulnerable period before the maturation of the adaptive immune system. Identification of disease-modifying genotypes may help target preventative strategies in high-risk infants.

Abstract
OBJECTIVE The analysis of intraepithelial lymphocytes (IELs) by flow cytometry of duodenal biopsies-the 'IEL' lymphogram-has been proposed as a diagnostic test for coeliac disease. However, its clinical applicability has been limited due to variability in methods and definitions. This study set out to define useful parameters for the application of the IEL lymphogram to the diagnosis of coeliac disease. DESIGN Flow cytometry was performed on 117 sets of duodenal biopsies in 107 adult patients with active coeliac disease, long-term coeliac disease on a gluten free diet and a control group. The initial 95 samples were used for hypothesis generation for the subsequent samples comprising 12 patients with coeliac disease and 10 controls. RESULTS Rather than using single linear cut-offs for CD3 and T-cell receptor γδ (TCRγδ)+ve IELs, a discriminant function was identified as %CD3+ve IELs+2x(%TCRγδ+IELs)>100. This differentiated coeliac disease from control biopsies in the hypothesis generating group. These results were replicated in the validation group and found to be independent of histology in patients on long-term gluten free diet up to 12 years (combined sensitivity, 98.5%; specificity, 97.7%). CONCLUSIONS Flow cytometric analysis of IELs is a highly sensitive and specific adjunct to serology and histological examination for the diagnosis of coeliac disease, even in individuals with coeliac disease following a gluten free diet who exhibit normal duodenal histology.

Abstract
A systematic review of pharmacogenomic studies capturing adverse drug reactions (ADRs) related to asthma medications was undertaken, and a survey of Pharmacogenomics in Childhood Asthma (PiCA) consortia members was conducted. Studies were eligible if genetic polymorphisms were compared with suspected ADR(s) in a patient with asthma, as either a primary or secondary outcome. Five studies met the inclusion criteria. The ADRs and polymorphisms identified were change in lung function tests (rs1042713), adrenal suppression (rs591118), and decreased bone mineral density (rs6461639) and accretion (rs9896933, rs2074439). Two of these polymorphisms were replicated within the paper, but none had external replication. Priorities from PiCA consortia members (representing 15 institution in eight countries) for future studies were tachycardia (SABA/LABA), adrenal suppression/crisis and growth suppression (corticosteroids), sleep/behaviour disturbances (leukotriene receptor antagonists), and nausea and vomiting (theophylline). Future pharmacogenomic studies in asthma should collect relevant ADR data as well as markers of efficacy.

Abstract
BACKGROUND The Gly-to-Arg substitution at the 16 position (rs1042713) in the β2-adrenoceptor gene (ADRB2) is associated with enhanced downregulation and uncoupling of β2-receptors. OBJECTIVES We sought to undertake a meta-analysis to test the hypothesis that there is an interaction between the A allele of rs1042713 (Arg16 amino acid) and long-acting β-agonist (LABA) exposure for asthma exacerbations in children. METHODS Children with diagnosed asthma were recruited in 5 populations (BREATHE, Genes-Environments and Admixture in Latino Americans II, PACMAN, the Paediatric Asthma Gene Environment Study, and the Pharmacogenetics of Adrenal Suppression with Inhaled Steroid Study). A history of recent exacerbation and asthma treatment was determined from questionnaire data. DNA was extracted, and the Gly16Arg genotype was determined. RESULTS Data from 4226 children of white Northern European and Latino origin were analyzed, and the odds ratio for exacerbation increased by 1.52 (95% CI, 1.17-1.99; P = .0021) for each copy of the A allele among the 637 children treated with inhaled corticosteroids (ICSs) plus LABAs but not for treatment with ICSs alone (n = 1758) or ICSs plus leukotriene receptor antagonist (LTRAs; n = 354) or ICSs plus LABAs plus LTRAs (n = 569). CONCLUSIONS The use of a LABA but not an LTRA as an "add-on controller" is associated with increased risk of asthma exacerbation in children carrying 1 or 2 A alleles at rs1042713. Prospective genotype-stratified clinical trials are now required to explore the potential role of rs1042713 genotyping for personalized asthma therapy in children.

Abstract
Hyperpolarized singlet states provide the opportunity for polarization storage over periods significantly longer than T1. Here, we show how the singlet state in a chemically equivalent proton spin system can be revealed by a weak power spin-lock. This procedure allowed the measurement of the lifetimes of the singlet state in protic solvents. The contributions of different intra- and intermolecular relaxation mechanisms to singlet lifetimes are investigated with this procedure.

Abstract
Aims: In the present study acute leukemic children were studied to determine the incidence and principal site of infection, correlation with absolute neutrophil count, causative organisms and to standardize the initial empirical anti microbial therapy. Materials and methods: A total 40 children in the age group 6 month to 12 year with acute leukemia relapse were included in this study. A total 82 infectious episodes including 61 febrile episodes were investigated for infectious etiology. Results: We found that the frequency of infections increased significantly with the degree of immunocompromisation specially neutropenia (ANC < 500/cmm). The skin and soft tissue was the commonest site of infection (26.83%), followed by respiratory tract (21.95%). Staphylococcus nonhemolytic coagulase-negative (34%), followed by Klebsiella (17%) were the most common organisms isolated from blood. Staphylococcus non-hemolytic coagulase-negative was also the commonest isolate (26%) from other sites of infection. Most strains were sensitive to Cloxacillin, cephalosporin and aminoglycosides. Conclusion: For the treatment of febrile episodes, empirical use of beta-lactamase resistant penicillin e.g. Cloxacillin or cephalosporin combined with an aminoglycosides with a broad spectrum antifungal like fluconazole in selective cases at the first sign of infection is recommended.

Abstract
The Atacama pathfinder experiment Sunyaev-Zel'dovich (APEX-SZ) instrument is a millimeter-wave cryogenic receiver designed to observe galaxy clusters via the Sunyaev-Zel'dovich effect from the 12 m APEX telescope on the Atacama plateau in Chile. The receiver contains a focal plane of 280 superconducting transition-edge sensor (TES) bolometers instrumented with a frequency-domain multiplexed readout system. The bolometers are cooled to 280 mK via a three-stage helium sorption refrigerator and a mechanical pulse-tube cooler. Three warm mirrors, two 4 K lenses, and a horn array couple the TES bolometers to the telescope. APEX-SZ observes in a single frequency band at 150 GHz with 1' angular resolution and a 22' field-of-view, all well suited for cluster mapping. The APEX-SZ receiver has played a key role in the introduction of several new technologies including TES bolometers, the frequency-domain multiplexed readout, and the use of a pulse-tube cooler with bolometers. As a result of these new technologies, the instrument has a higher instantaneous sensitivity and covers a larger field-of-view than earlier generations of Sunyaev-Zel'dovich instruments. The TES bolometers have a median sensitivity of 890 μK(CMB)√s (NEy of 3.5 × 10(-4) √s). We have also demonstrated upgraded detectors with improved sensitivity of 530 μK(CMB)√s (NEy of 2.2 × 10(-4) √s). Since its commissioning in April 2007, APEX-SZ has been used to map 48 clusters. We describe the design of the receiver and its performance when installed on the APEX telescope.

Abstract
BACKGROUND Using cyclodextrin with budesonide enables it to be formulated in a solution for nebulization. OBJECTIVE To observe the effects of a Captisol-enabled budesonide solution (CBIS), 60 microg twice daily, delivered via a nebulizer (eFlow), compared with a conventional budesonide suspension (Pulmicort Respules), 250 microg twice daily, delivered via another nebulizer (LC Plus), using fraction of exhaled nitric oxide (FE(NO)) and overnight urinary cortisol to creatinine ratio as the primary outcomes for efficacy and systemic bioactivity. METHODS A randomized, open-label, crossover study was conducted in 12 children with mild-to-moderate persistent asthma (aged 5-12 years). Measurements were performed after a 2-week steroid washout at baseline and at the end of each 2-week randomized treatment. RESULTS The nebulization time was shorter (95% confidence interval [CI], 0.83-5.63 minutes; P = .03) with CBIS (mean, 1.77 minutes) than with Pulmicort Respules (mean, 5.01 minutes). The reduction in FE(NO) with CBIS from pooled baseline was 2.45-fold (95% CI, 1.87-3.21; P < .001); and with Pulmicort Respules, 3.18-fold (95% CI, 2.26-4.47; P < .001). No statistically significant changes from pooled baseline in lung function and overnight urinary cortisol to creatinine ratio were observed with either treatment. CONCLUSIONS The nebulization time was shorter with CBIS compared with Pulmicort Respules. Both formulations exhibited similar anti-inflammatory activity in terms of reducing FE(NO), with no detectable difference between them when used in a putative microgram nominal dose ratio of 1:4. Neither formulation produced significant adrenal suppression.

Abstract
Cases of Acquired Aplastic Anaemia (AAA) in patients with a long history of pesticide exposure from agricultural fields have been investigated in our laboratory using an immunological approach. These patients showed moderate to severe degrees of bone marrow aplasia as a result of 9-12 years protracted exposure to pesticides which were mainly comprised of organophosphorous and organochloride compounds. The bone marrow aspirate culture was found to be severely deficient both in terms of differentiation and proliferation, and cell mediated immune function (CMI). We attempted ex vivo manipulation of the bone marrow population of patients in two different protocols: in one, stem cell factor (SCF), interleukin-3 (IL-3), and granulocyte-colony stimulating factor (G-CSF) were administered and, in the second set, cord blood-derived plasma factors (CBPF) were supplemented to evaluate the effects, if any. Simultaneously, two control groups including one for healthy normal control (N) and the second, for non-pesticide induced aplastic anaemia group of patients (NPAA) was also investigated for all the above parameters. Active colony formation and improved cellular immune activity (CMI) was observed more frequently in the CBPF treated group rather than that in the cytokine treated group. Surprisingly, administration of cytokines in the first set and CBPF in the second set triggered CD34 (+) cell generation as revealed through flow cytometric analysis (FACS). The effect was more pronounced in the second set. Investigations carried out with NPAA showed relatively insignificant effects with both cytokine and CBPF set up. The investigations indicated that AAA as induced by pesticides could be therapeutically manipulated by exogenous cytokines and growth factors and, more efficiently, by CBPF by way of immunopotentiation through microenvironmental supplementation.

Abstract
In Nephrotic Syndrome the amount of protein excretion is a reflection of activity of disease. Quantitative measurement of proteinuria by a 24-hour urine collection has been the accepted method of evaluation. Recent studies have shown that calculation of protein/creatinine ratio in a spot urine sample correlates well with the 24-hour urine protein (24-HUP) excretion. A study was conducted to compare the accuracy of a spot urinary protein/creatinine ratio (P/C ratio) and urinary dipstick with the 24-hour urine protein. Fifty two samples from 26 patients of nephrotic syndrome were collected. This included a 24-hour urine sample followed by the next voided random spot sample. The protein/creatinine ratio was calculated and dipstick was performed on the spot sample. This was compared with the 24-hour urine protein excretion. The correlation between the three samples was statistically highly significant (p<0.001) for all levels of proteinuria. The normal value of protein/creatinine ratio in Indian children was also estimated on 50 normal children admitted in the ward without any renal diseases calculated to be 0.053 (SE of mean+/-0.003).

Abstract
BACKGROUND Filaggrin (FLG) null mutations are important genetic predisposing factors for atopic asthma and have recently been shown to influence controller and reliever medication needs in asthmatic children. Our objective was to study the role of FLG null alleles in asthma exacerbations. METHODS FLG mutations R501X and 2282del4 were assayed in 1135 individuals ranging from 3 to 22 years old with asthma from Tayside and Dumfries, Scotland. Asthma exacerbations over the previous 6 months were also studied. RESULTS The FLG mutations were significantly associated with greater risk of exacerbations in children with asthma. Exacerbations were significant for the R501X but not the 2282del4 mutation and the combined genotype compared to the wild-type with odds ratios of 1.97 (95% CI, 1.19-3.22; P = 0.009) and 1.61 (95% CI, 1.08-2.40; P = 0.021), respectively. Individuals with FLG null alleles were more likely to require oral steroids (31.4%vs 19.5%; OR = 1.89; P = 0.021) for their exacerbations. There was also a 1.71-fold increased risk (42.6%vs 30%; P = 0.041) of school absence owing to asthma exacerbations in asthmatic individuals with FLG null mutation. On sub-group analysis, the effect of FLG mutations on asthma exacerbations is significant (P = 0.045) only for participants with relatively mild asthma controlled on inhaled steroids, with inhaled albuterol according to need. CONCLUSION In addition to their effect on asthma medication requirements reported previously, there is an association between the presence of FLG null mutations and the risk of asthma exacerbations in asthmatic children and young adults.

Abstract
For a given DNA sequence, it is well known that pair wise alignment schemes are used to determine the similarity with the DNA sequences available in the databanks. The efficiency of the alignment decides the type of amino acids and its corresponding proteins. In order to evaluate the given DNA sequence for its proteomic identity, a pattern matching approach is proposed in this paper. A block based semi-global alignment scheme is introduced to determine the similarity between the DNA sequences (known and given). The two DNA sequences are divided into blocks of equal length and alignment is performed which minimizes the computational complexity. The efficiency of the alignment scheme is evaluated using the parameter, percentage of similarity (POS). Four essential DNA version of the amino acids that emphasize the importance of proteomic functionalities are chosen as patterns and matching is performed with the known and given DNA sequences to determine the similarity between them. The ratio of amino acid counts between the two sequences is estimated and the results are compared with that of the POS value. It is found from the experimental results that higher the POS value and the pattern matching higher are the similarity between the two DNA sequences. The optimal block is also identified based on the POS value and amino acids count.

Abstract
Wilson disease (WD) is an autosomal recessive disorder caused by defects in the copper-transporting P-type ATPase gene (ATP7B) resulting in the accumulation of copper in the liver and the brain. We identified prevalent mutations in the ATP7B of Indian WD patients and attempted to correlate those with the disease phenotype. Patients from 62 unrelated families and their first-degree relatives comprising 200 individuals were enrolled in this study. Three dinucleotide repeat markers flanking WD locus and a few intragenic SNPs were used to determine the genotypes and construct haplotypes of the patients. Seven recurring haplotypes accounting for 58% of the total mutant chromosomes were identified, and four underlying defects in the ATP7B representing 37% of WD chromosomes were detected. In addition, five other rare mutations were characterized. Thus a total of nine mutations including five novel changes were identified in the ATP7B of WD patients. Interestingly, homozygotes for different mutations that would be expected to produce similar defective proteins showed significant disparity in terms of organ involvement and severity of the disease. We also observed WD patients with neurological symptoms with little or no manifestation of hepatic pathogenesis. In one WD family, the proband and a sib had remarkably different phenotypes despite sharing the same pair of mutant chromosomes. These findings suggest a potential role for yet unidentified modifying loci for the observed phenotypic heterogeneity among the WD patients.

Abstract
A hospital based prospective study was carried out from 1st October 1998 to 30th September 1999 on children with clinical diagnosis of bronchiolitis in OPD and indoor patients of the Department of Paediatric Medicine, Medical College Kolkata. The objective of the study was to find out the proportional case rate and clinico epidemiological features of the disease. The effectiveness of nebulized salbutamol among bronchiolitis children was also looked into. The proportional case rate was found to be 4.65%. Low birth weight (LBW)/premature babies (51.11%) malnutrition (40%), nonimmunization (55.55%) & non breastfeeding practices (48.88%) were significant risk factors for severe bronchiolitis. Response to nebulized salbutamol was remarkably higher (70%) in 6m to 12m age group.

Abstract
BACKGROUND Cholelithiasis produces diverse histopathological changes in gallbladder mucosa namely acute inflammation, chronic inflammation, glandular hyperplasia, granulomatous inflammation, cholesterosis, dysplasia, and carcinoma. Gallstones have different chemical composition. They may be cholesterol, pigment or mixed stones. The aim of this prospective study was to see if any correlation existed between the chemistry of gallstones and any particular histopathologic picture. METHODS Between May 1997 and December 1997 we diagnosed and operated on 40 patients with cholelithiasis. Diagnosis was established by ultrasound. After operation gallstones were sent for chemical analysis to detect presence of calcium bilirubinate and cholesterol. Serial sections of gallbladder from fundus to neck were stained by haematoxylin and eosin, and studied. RESULTS Out of 40 patients (n = 40) 29 were females and 11 were males. The mean age of our patients was 38 +/- 21 years with a median of 40 years. Median age of males was 48 years compared to 38 years for females. Twenty-eight patients had mixed stones, 8 had pigment stones and 4 had cholesterol stones. Out of 28 patients with mixed stones 14 had histological picture of chronic cholecystitis, 8 had granulomatous cholecystitis, 4 had adenomatous hyperplasia, 1 had dysplasia and 1 had carcinoma. All 8 patients having pigment gallstones had chronic cholecystitis. Out of 4 patients with cholesterol gallstones, 2 had chronic cholecystitis, 1 had adenomatous hyperplasia and 1 had cholesterosis. Gallbladder having pigment stones were devoid of Rokitansky-Aschoff sinuses. CONCLUSION Adenomatous hyperplasia and Rokitansky-Aschoff sinuses were not seen in gallbladder containing pigment stones but seen in gallbladders containing mixed and cholesterol stones in our study. Cholesterol may be a more potent stimulus for glandular hyperplasia or glandular hyperplasia may responsible for formation of cholesterol rich stones.

Abstract
Biological Response Modifiers (BRMs) including interleukin-2 (IL-2), interferon-gamma (IFN-gamma) and sheep erythrocytes (SRBC) protected N,N'-ethylnitrosourea (ENU) induced leukaemic mice. Two cell types from the bone marrow were isolated in density specific gradient representing two distinct compartments, the low density cells being more CD34 positive than the high density group. Investigations with the functional efficacy of such compartments revealed significant improvement of cytotoxic efficacy and phagocytic burst at the high density compartment (HDC) level. The high density compartment was found to be more responsive towards the BRMs compared to the cells of the low density compartment (LDC). It was suggested that use of BRMs in vivo can stimulate a potent functional progenitor compartmentalization in normal as well as leukaemic mice. These observations are expected to help a logistic approach towards combined BRM therapy at the clinical level.

Abstract
As networks have proliferated, questions have arisen regarding which structure is optimal. To obtain an answer from the hospital perspective, the authors conducted a survey of New York State hospitals to determine how network integration, complexity, and financial risk sharing relate to measures of financial performance during the period of 1991-1995. Of the 64 hospitals indicating a network affiliation by 1995, 67.2 percent listed some network risk-sharing activity. The least integrated networks were associated with the smallest improvements in throughput, and the most complex were associated with the largest negative changes in operating margins. During the first 2 years of network membership, hospitals joining risk-sharing networks experienced operating margin gains averaging 12 percentage points higher than hospitals joining networks without risk sharing; however, this difference dissipated in later years. Networks with higher levels of integration, lower levels of complexity, and which involve some risk-sharing between affiliates are most likely to experience improved hospital financial performance during the network's initial years.

Abstract
OBJECTIVE Based on the assumption that people without health insurance have limited access to the primary care services needed to prevent unnecessary hospitalizations for asthma, the authors hypothesized that insurance is a factor in the strength of the association between hospital admissions for asthma and exposure to air pollution. They tested this hypothesis with 1991-1994 data from central Los Angeles. METHODS The authors analyzed the effect of insurance status on the association between asthma-related hospital admissions and exposure to atmospheric particulates (PM10) and ozone (O3) using hospital discharge and air quality data for 1991-1994 for central Los Angeles. They used regression techniques with weighted moving averages (simulating distributed lag structures) to measure the effects of exposure on overall hospital admissions, admissions of uninsured patients, admissions for which MediCal (California Medicaid) was the primary payer, and admissions for which the primary payer was another government or private health insurance program. RESULTS No associations were found between asthma admissions and O3 exposure. An estimated increase from 1991 to 1994 of 50 micrograms per cubic meter in PM10 concentrations averaged over eight days was associated with an increase of 21.0% in the number of asthma admissions. An even stronger increase--27.4%--was noted among MediCal asthma admissions. CONCLUSIONS The authors conclude that low family income, as indicated by MediCal coverage, is a better predictor of asthma exacerbations associated with air pollution than lack of insurance and, by implication, a better predictor of insufficient access to primary care.

Abstract
Out of 6319 live born babies, 310 (4.9%) with high risk factors and with clinical suspicion of sepsis were studied for incidence pattern of neonatal infections. Incidence of neonatal infection was 2.56% in normal weight babies and 8.42% in low birth weight babies. Total culture positivity was 48.38%. Klebsiella was the most frequent offender, followed by Staph aureus and Staph epidermidis. Majority of klebsiella species were sensitive to ceftriaxone (86%), amikacin (84%) and ceftazidime (80%). Ceftriaxone was effective against Staph aureus (95%) and Staph epidermidis (95%). Overall fatality was 17.1%, distinctly higher in low birth weight group (22.06%) than normal weight group (6.18%).

Abstract
Sodium antimony gluconate (SAG) is the mainstay of treatment for visceral leishmaniasis (VL) or kala-azar. In view of the increasing incidence of refractoriness to SAG in India, we compared the levels of parasite-specific IgG and IgG subclasses in 20 longitudinally followed up kala-azar patients. In both SAG-responsive (n = 10) and unresponsive patients (n = 10), the levels of total IgG, IgG1, IgG2, IgG3 and IgG4 were increased, the rank order being IgG1 > IgG2 > IgG3 = IgG4. Following treatment, a significant decrease in total IgG and the four subclasses occurred in the SAG-responsive group, whereas in the SAG-unresponsive group these levels were unchanged or slightly increased. Therefore, monitoring of IgG1 and IgG2 levels in Indian kala-azar patients is a good serologic alternative to monitoring the disease status.

Abstract
A total of 405 cases of fever who were either admitted to the Hospital or attended in paediatric out patient Department or Emergency of Medical College Hospital, Calcutta between January '95 and November '95 were included in the study. Majority of cases presented with usual features of malaria like fever with chill and rigor, hepatosplenomegaly, pallor. Apart from these, complicated manifestations like shock, convulsion D.I.C and jaundice were also observed. Some unusual presentations with severe diarrhoea, dehydration and features like that of acute viral respiratory tract infection were highly confusing in terms of clinical diagnosis. P. falciparum was observed in 35.5% of cases. Overall therapeutic response to chloroquin was good, However, two patients died of cerebral Malaria. Five cases of severe malaria were caused by P. vivax however, other etiological features could not be found to attribute the severe nature of these illnesses.

Abstract
A prospective study on 90 neonates born to age matched normal mothers (set I) and mothers (set II) with pre-eclamptic toxaemia (PET) was undertaken to assess and compare the humoral immunity status of the neonates. All of them had normal vaginal delivery. IgG, IgA and IgM were estimated by radial immunodiffusion technique from cord blood of neonates. It was observed that IgA and IgM levels were insignificant in the cord blood. IgG level was low in normal birth weight (NBW) neonates born to PET mothers, when compared to that of NBW neonates born to normal mothers. Again low birth weight (LBW) babies of both the sets showed lower values of IgG than that of NBW babies. Apgar scoring showed direct relationship with IgG levels e.g., higher the Apgar score higher the level of IgG. Thus the IgG level was directly related to the birth weight of the neonates of the respective sets as well as with the Apgar scoring of the neonates.

Abstract
Treatment with hepatotoxin namely carbon tetrachloride (CCl4) (0.1 ml/100 g of body weight; twice a week) induced acute hepatic necrosis in Swiss albino mice (male; body weight 30 g +/- 2), with significant alteration in the activities of glutamic oxaloacetic transaminase (GOT); glutamic pyruvic transaminase (GPT); alkaline phosphatase (AP) and serum bilirubin. Administration of a protein fraction isolated from the leaves of C. indicus counteracted the action of CCl4 on transaminase, phosphatase showing hepatoprotection. Daily treatment with a purified protein fraction 'X' from the above plant (0.5 mouse ml i.p; 50-60 micrograms/ml) for a period of 7, 14, 21 days respectively showed decreased activities of serum transaminases alkaline phosphatase and decreased levels of serum bilirubin. These findings were further confirmed by histopathological study of liver.

Abstract
Early neonatal morbidity & mortality were studied in 7972 viable live born babies over one year period in Medical College, Calcutta. Early neonatal morbidity and mortality rate were 66.85 & 32.86 respectively. About 48% of Early neonatal deaths occurred in 1st 48 hours & 80% within first 72 hours of life. Early neonatal mortality rate per 1000 was maximum in babies born of a primi (43.03) and grand multiparous mother (103.89); maternal age less than 20 yrs. (44.15), and more than 30 yrs. (46.04) & in multiple pregnancy (142.85). It was highest in breech delivery (114.28) & with maternal disease like dribling (179), hypertension (146) & APH (116).
