Prevalence of chronic kidney disease risk factors among low birth weight adolescents.

BACKGROUND: By adulthood, low birth weight infants have an increased risk for chronic kidney disease (CKD). The extent to which objective CKD risk factors are present at earlier ages is unclear. METHODS: We analyzed 5352 participants aged 12-15 years in the National Health and Nutrition Examination Survey, 1999-2012. Participants were classified as low birth weight (LBW; < 2500 g), very low birth weight (VLBW; < 1500 g), or normal (2500-4000 g) by parental/proxy recall. Albuminuria (albumin/creatinine 30 - <300 mg/g), decreased estimated glomerular filtration rate (eGFR; < 90 ml/min/1.73 m(2); Counahan-Barratt), and elevated systolic blood pressure (BP; ≥ 95th percentile for age, height, and sex) were considered CKD risk factors. RESULTS: While albuminuria did not vary by birth weight, elevated blood pressure (BP) and decreased eGFR occurred more frequently in LBW/VLBW adolescents (elevated BP: LBW 6.0 %, VLBW 11.2 %, normal 2.4 %; decreased eGFR: LBW 23.2 %, VLBW 32.5 %, normal 16.1 %). After multivariable adjustment, LBW/VLBW adolescents had greater odds for both elevated BP (LBW: OR 2.90, 95 % CI 1.48-5.71; VLBW: 5.23; 1.11-24.74) and decreased eGFR (LBW: 1.49, 95 % CI 1.06-2.10; VLBW 2.49, 95 % CI 1.20-5.18). CONCLUSIONS: In the U.S. population, both decreased eGFR and elevated systolic BP occur frequently among adolescents with history of LBW/VLBW.

Examining the Backpack Weight Relative to Students' Body Weight Among Urban and Rural Schoolchildren: A Cross-Sectional Study.

Background Schoolbags or backpacks have been an essential part of the education system for a long time. However, a hefty backpack causes the child to arch the back excessively or bend their head and trunk forward to withstand the weight of the schoolbag. If the student carries the backpack on one shoulder, he/she bends to the opposite side to compensate for the extra weight, which may damage the shoulders and spine. Considering these factors, the main aim of this study was to investigate the percentage of backpack weight in proportion to the student's body weight regarding the new guidelines among urban and rural schoolchildren aged 12 to 15 years in Bangalore, Karnataka. Methodology In southern India, over a year, a cross-sectional study was conducted with 500 students who voluntarily participated after providing written consent. They completed a questionnaire, underwent vital and anthropometric measurements, and had their weights measured, including the weights of their backpacks. Sample bags were inspected to determine contributing weight factors and evaluate adherence to timetables. Results The average weight carried by children of all ages was 6.53 kg, averaging 13.53% of their body weight. Among males, the percentage carrying backpacks weighing over 10% of their body weight was 80.9%, while among females, it was 85.7%. Of all the males carrying bags weighing more than 10% of their body weight, 67.7% attended government schools, while 32.3% attended private schools. Among females studying in government schools, 63.6% carried backpacks weighing more than 10% of their body weight, while among those in private schools, 36.4% carried bags exceeding that weight. Conclusions The study concluded that despite regulations being implemented on backpack weight for children, a significant number still carry bags exceeding 10% of their body weight among both urban and rural school children. This could elevate pressure on neck and back muscles, leading to excessive fatigue and potential damage to the skeletal system, ultimately contributing to spinal deformities.

Clinical, Radiological, and Lung Function Characteristics of Post-tuberculosis Bronchiectasis: An Experience From a Tertiary Care Center in India.

Introduction Among chronic respiratory diseases, bronchiectasis is one of the important causes of mortality and morbidity in developing countries. Objective This study aimed to assess the clinical, radiological, microbiological, and pulmonary function profiles of adult patients with post-tubercular bronchiectasis. Methods We enrolled 138 patients with bronchiectasis confirmed by high-resolution CT scans from July 2017 to August 2018. Results A total of 138 patients with bronchiectasis were enrolled. The data from 132 patients were analyzed; six patients were excluded from the study. The mean age of post-TB bronchiectasis (post-tuberculosis bronchiectasis) patients was 36.08±13.08, which was lower than the non-tuberculosis bronchiectasis group. The proportion of the male population was more in the post-TB bronchiectasis group (54.55% vs. 37.88%, p=0.48). Smoking prevalence was high in post-TB bronchiectasis (27.27% vs. 12.12%, p=0.04). The predominant symptom was cough in the post-tubercular bronchiectasis group (48.5% vs. 41.7%, p=0.019). The history of the recurrent common cold was seen most frequently in non-post-tubercular bronchiectasis (40.9% vs. 12.9%, p=0.001). The most common radiological variant of bronchiectasis found in all patients was a cystic type (75%). The most common site of involvement was the left lower lobe, followed by the lingula in all patients and post-tuberculosis bronchiectasis patients. Pulmonary function on spirometry revealed obstructive, restrictive, and mixed patterns in 55%, 25%, and 15%, respectively. Patients with post-tuberculosis bronchiectasis had lower lung function post-FEV1/FVC (forced expiratory volume in one second/forced vital capacity) ratio (70.31±15.56 vs. 76.85±11.82, p=0.015). Binary multivariate logistic regression analysis showed that only recurrent cough cold was a significant independent risk factor for post-TB bronchiectasis. Conclusion Post-tuberculosis, and bronchiectasis followed by post-infectious causes, were the most common causes of bronchiectasis and poor lung function.

Characterization and development of transcriptome-derived novel EST-SSR markers to assess genetic diversity in Chaetomium globosum.

Chaetomium globosum Kunze, an internationally recognized biocontrol fungus. It mycoparasitizes various plant pathogens and produce antifungal metabolites to suppress the growth of pathogenic fungi. Lack of detailed genome level diversity studies has delimited the development and utilization of potential C. globosum strains. The present study was taken to reveal the distribution, identification, and characterization of expressed sequence tag-simple sequence repeats (EST-SSRs) in C. globosum. RNA-Seq experiment was performed for C. globosum potential isolate Cg2 (AY429049) using Illumina HiSeq 2500. Reference-guided de novo assembly yielded 45,582 transcripts containing 27,957 unigenes. We generated a new set of 8485 EST-SSR markers distributed in 5908 unigene sequences with one SSR locus distribution density per 6.1 kb. Six distinct classes of SSR repeat motifs were identified. The most abundant were mononucleotide repeats (51.67%), followed by tri-nucleotides (36.61%). Out of 5034 EST-SSR primers, 50 primer pairs were selected and validated for the polymorphic study of 15 C. globosum isolates. Twenty-two SSR markers showed average genetic polymorphism among C. globosum isolates. The number of alleles (Na) per marker ranges from 2 to 4, with a total of 74 alleles detected for 22 markers with a mean polymorphism information content (PIC) value of 0.4. UPGMA hierarchical clustering analysis generated three main clusters of C. globosum isolates and exhibited a lower similarity index range from 0.59 to 0.85. Thus, the newly developed EST-SSR markers could replace traditional methods for determining diversity. The study will also enhance the genomic research in C. globosum to explore its biocontrol potential against phytopathogens.

Polysaccharide and monosaccharide guided liver delivery of Sorafenib Tosylate - A nano-strategic approach and comparative assessment of hepatospecificity.

Hepatospecific delivery by ligand based receptor targeting is an established strategy to augment therapy associated with liver diseases and disorders. Previously, we have investigated the effect of ligand headgroup on cellular uptake mediated by the asialoglycoprotein receptor by in silico and in vitro approach. In this paper, we report the design of agarose based liposomes for delivery to liver cancer cells and provide a proof of concept of the targeting efficiency against galactose liposomes using an in vivo approach. Sorafenib Tosylate loaded targeting liposomes were developed and optimized using factorial design. Comparative evaluation including cell cytotoxicity, pharmacokinetics and biodistribution and hepatospecific uptake was performed for both the liposomal systems. The formulations possessed a particle size of 150 - 180 nm and a zeta potential of 30 - 60 mV depending on the amount of ligand and drug loading, with more than 90% entrapment efficiency. A two-fold increase in cytotoxicity was observed with agarose-based liposomes as compared to galactose based liposomes. In vivo PK evaluation indicated a reduction in half life of drug when loaded in agarose ligand loaded system, probably due to greater uptake in the liver as evidenced in biodistribution study. Intrahepatic disposition revealed a higher PC/NPC uptake ratio with the targeted systems as compared to conventional liposomes, although the agarose-based system resulted in highest uptake ratio. A biocompatible platform for specific delivery of drugs to hepatocytes was established validating a rational approach to design liver targeting systems.

Temporal transcriptome of tomato elucidates the signaling pathways of induced systemic resistance and systemic acquired resistance activated by Chaetomium globosum.

C. globosum is an endophytic fungus, which is recorded effective against several fungal and bacterial diseases in plants. The exclusively induce defense as mechanism of biocontrol for C. globosum against phyto-pathogens is reported. Our pervious study states the effectiveness of induced defense by C. globosum (Cg), in tomato against Alternaria solani. In this study the temporal transcriptome analysis of tomato plants after treatment with C. globosum was performed for time points at 0 hpCi, 12 hpCi, 24 hpCi and 96 phCi. The temporal expression analysis of genes belonging to defense signaling pathways indicates the maximum expression of genes at 12 h post Cg inoculation. The sequential progression in JA signaling pathway is marked by upregulation of downstream genes (Solyc10g011660, Solyc01g005440) of JA signaling at 24 hpCi and continued to express at same level upto 96 hpCi. However, the NPR1 (Solyc07g040690), the key regulator of SA signaling is activated at 12 h and repressed in later stages. The sequential expression of phenylpropanoid pathway genes (Solyc09g007920, Solyc12g011330, Solyc05g047530) marks the activation of pathway with course of time after Cg treatment that results in lignin formation. The plant defense signaling progresses in sequential manner with time course after Cg treatment. The results revealed the involvement of signaling pathways of ISR and SAR in systemic resistance induced by Cg in tomato, but with temporal variation.

Smart access development for classifying lung disease with chest x-ray images using deep learning.

Recently the world has come across a pandemic disease known as covid-19. The presence of symptoms of covid-19 and pneumonia may be alike to other types of lung illnesses. So, because of this, it is difficult for the affected person or medical experts to identify the condition. Chest x-ray provides general orientation which can be an initial investigative study in the analysis of lung diseases. Information from retenogram studies help the finding of covid-19 and pneumonia affecting the lungs. We use a Convolution Neural Network (CNN) in Tensor Flow and Keras based covid-19, pneumonia classification. The best fit model of CNN is then deployed in the Django framework for providing a better user interface and predicting the output.

Transcriptome Reprogramming of Tomato Orchestrate the Hormone Signaling Network of Systemic Resistance Induced by Chaetomium globosum.

Chaetomium globosum is a potential biological control agent effective against various plant pathogens. Several reports are available on the mycoparastism and antibiosis mechanisms of C. globosum against plant pathogenic fungi, whereas a few states induced resistance. The potential induced defense component of C. globosum (Cg-2) was evaluated against early blight disease of tomato (Solanum lycopersicum) and further, global RNA sequencing was performed to gain deep insight into its mechanism. The expression of marker genes of hormone signaling pathways, such as PR1, PiII, PS, PAL, Le4, and GluB were analyzed using real-time quantitative reverse transcription PCR (qRT-PCR) to determine the best time point for RNA sequencing. The transcriptome data revealed that 22,473 differentially expressed genes (DEGs) were expressed in tomato at 12 h post Cg-2 inoculation as compared with control plants and among these 922 DEGs had a fold change of -2 to +2 with p < 0.05. The Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis revealed that most of the DEGs were belonging to metabolic pathways, biosynthesis of secondary metabolites, plant-pathogen interaction, chlorophyll metabolism, and plant hormone signal transduction. Gene Ontology (GO) analysis revealed that DEGs were enriched mainly related to binding activity (GO:0005488), catalytic activity (GO:0003824), metabolic process (GO:0008152), cellular process (GO:0009987), response to stimulus (GO:0050896), biological regulation (GO:0065007), and transcription regulator activity (GO:0140110). The gene modulations in hormone signaling transduction, phenylpropanoid biosynthesis, and mitogen-activated protein kinases (MPK) signaling indicated the upregulation of genes in these pathways. The results revealed active participation of jasmonic acid (JA) and salicylic acid (SA) signaling transduction pathways which further indicated the involvement of induced systemic resistance (ISR) and systemic acquired resistance (SAR) in the systemic resistance induced by Cg-2 in tomato.

Transcriptome Profiling Provides Insights Into Potential Antagonistic Mechanisms Involved in Chaetomium globosum Against Bipolaris sorokiniana.

Chaetomium globosum Kunze is recognized as a potential biocontrol fungus against spot blotch of wheat caused by Bipolaris sorokiniana. Its molecular mechanism of biocontrol activity and the biosynthetic pathways involved have not been yet elucidated. Here, global transcriptome profiling of C. globosum strain Cg2 during interaction with B. sorokiniana isolate BS112 using RNA-seq was performed in order to gain insights into the potential mechanisms of antagonism. The Illumina HiSeq platform (2 × 150 bp) yielded an average of 20-22 million reads with 50-58% GC. De novo assembly generated 45,582 transcripts with 27,957 unigenes. Transcriptome analysis displayed distinct expression profiles in the interaction (Cg2-BS112), out of which 6,109 unique differentially expressed genes were present. The predominant transcripts classified as genes involved in "catalytic activity" constituted 45.06%, of which 10.02% were associated with "hydrolytic activity" (GO:0008152), and similarly, in the biological process, 29.18% of transcripts were involved in "metabolic activity" (GO:0004096 and GO:0006979). Heat map and cluster categorization suggested an increase in the expression levels of genes encoding secondary metabolites like polyketide synthase (GO:0009058), S-hydroxymethyl glutathione dehydrogenase (GO:0006069), terpene cyclase (EC 4.2.3.-), aminotran_1_2 domain-containing protein (GO:0009058), and other hydrolytic CAZYmes such as the glycosyl hydrolase (GH) family (GH 13, GH 2, GH 31, and GH 81; GO:0005975), cellulase domain-containing protein, chitinases, ß-1, 3-glucanases (GO:0004565), glucan endo-1,3-beta-glucanase (GO:0052861), and proteases (GO:0004177). The obtained RNA-seq data were validated by RT-qPCR using 20 randomly chosen genes, showing consistency with the RNA-seq results. The present work is worldwide the first effort to unravel the biocontrol mechanism of C. globosum against B. sorokiniana. It generated a novel dataset for further studies and facilitated improvement of the gene annotation models in the C. globosum draft genome.

Curious case of primary pulmonary mucoepidermoid carcinoma.

Pulmonary mucoepidermoid carcinoma (MEC) is an uncommon tumor constituting only 0.1% to 0.2% of all lung carcinoma. It is classified under "salivary gland type" tumors in the World Health Organization (WHO) classification of lung cancers. It generally carries a better prognosis than the more common small cell and nonsmall cell lung carcinomas. It is pathologically classified into high-grade and low-grade tumors. High-grade tumors are usually unresectable at presentation. However, surgery is the mainstay of treatment, which aims at surgically negative margins for a complete cure. In our patient, pulmonary MEC presented with intrathoracic mass with pericardial effusion. It came out to be low-grade neoplasm, which was treated with platinum-based doublet chemotherapy and responded well with near-total disappearance of tumor, like a vanishing lung tumor.

Clinical, demographic and radiological profile of smoker COPD versus nonsmoker COPD patients at a tertiary care center in North India.

INTRODUCTION: Cigarette smoking is the most predominant risk factor for development of chronic obstructive pulmonary disease (COPD). However, a considerable amount of patients do develop COPD without exposure to cigarette smoking. We aimed to analyze the incidence, demographic and clinical profile of nonsmoker COPD subjects at a tertiary care center. METHODS: In this prospective observational study, 410 patients were screened for dyspnea. On the basis of spirometry findings, 360 patients were diagnosed as COPD and enrolled into the study. Patients were categorized into 2 groups on the basis of smoking habits (smoker and nonsmoker COPD). Clinical and demographic attributes were compared in between these two groups. This study was conducted over a period of one year, from August 2014 to July 2015. All statistical analyses were performed using Statistical Package for the Social Sciences version 19.0 (SPSS Inc, Chicago, IL, USA). Values were considered to be statistically significant at P < 0.05. RESULTS: Out of 360 COPD cases, about 2/3rd (60%) were smokers and the rest nonsmokers. Majority of the patients were in the age group of 51-70 years. The mean age of smokers with COPD was significantly higher than nonsmokers with COPD (59.29 ± 10.28 years vs. 53.90 ± 8.77 years; P = 0.0001). Overall, males were predominant (57.2%) but there were higher number of female patients in nonsmoker group (25% vs. 70%; P = 0.001). At presentation, majority of nonsmoker with COPD were in GOLD severity grade II while in the smoking cohort majority were in GOLD severity Grade III. Among the 144 nonsmoker COPD patients, the most important and statistically significant risk factor was exposure to biomass smoke (68.06%). Other risk factors were long-standing asthma (37.50%), lower respiratory tract infection in childhood (32.60%), exposure to outdoor air pollution (17.92%). CONCLUSION: Nonsmoker COPD is emerging as a distinctive phenotype. They have less impairment in airflow limitation, and a lower prevalence of emphysema, chronic cough, and sputum compared with their smoking counterparts.

Obstructive sleep apnea risk for driving license applicants in India - A community based study.

OBJECTIVES: To determine the risk of obstructive sleep apnea (OSA) for male permanent driving license (DL) applicants of Lucknow, India. MATERIAL AND METHODS: In this cross-sectional community based, study body mass index, waist-hip ratio, blood pressure of each subject were determined as an anthropometric parameter along with the history of habit of smoking, tobacco chewing, alcohol consumption. STOP-Bang (Snoring, Tired or sleepy, Observed apnea, high blood Pressure, Body mass index, Age, Neck, Gender) Questionnaire - a scoring risk assessment tool - was applied for assessment of OSA risk (high OSA risk defined by score ≥ 3) for 542 male DL recipients at 2 Regional Transport Office (RTO) centers in Lucknow, India. The statistical software SPSS 17.0 was applied to the testing. RESULTS: In total 23% (N = 125) of participants were found with the risk of OSA. High blood pressure (≥ 140/90 mm Hg) was found for the maximum number of participants (40.5%) followed by neck circumference > 40 cm (17.1%), age (> 50 years old) (15.3%), snoring (12.3%) and tired/sleepy (10.5%). Mean values of age, anthropometric measurements and blood pressure were observed significantly higher (p < 0.001) for participants with the OSA risk. In this population the risk of OSA risk (STOP-Bang score ≥ 3) was observed for 6.7% of young (< 35 years old), 34% of middle (35-45 years old) and 73% of elder age adults (> 45 years old). CONCLUSIONS: In view of findings of this study a high number of male driving license applicants were observed with the risk of OSA. Therefore efforts should be made to develop a national screening guideline/protocol for the OSA risk assessment for driving license applicants in India. This may reduce the possibility of road traffic accidents due to the OSA-associated fatigue and drowsiness behind the wheels. Int J Occup Med Environ Health 2018;31(1):25-36.

Multiple abdominal abscesses - A not so common presentation of NTM.

Non-tuberculous Mycobacteria/Mycobacterium other than tuberculosis (MOTT) are ubiquitous organisms. They are acid fast bacilli often giving trouble to the physician to distinguish it from Mycobacterium tuberculosis. These organisms are a menace for the treating physician as when to treat and when not to treat. They are often difficult to diagnose and may present in a variety of forms with propensity to cause number of infections of different body parts and organs. They are more common in immunocompromised individuals e.g. HIV infection. Here we are reporting a not so common manifestation of NTM which presented as multiple abdominal abscesses in a middle aged female probably secondary to surgical site infection, however she responded dramatically to the designed treatment.

Study of oxidative stress biomarkers in chronic obstructive pulmonary disease and their correlation with disease severity in north Indian population cohort.

BACKGROUND: Oxidant-antioxidant imbalance forms a prime component in pathogenesis of chronic obstructive pulmonary disease (COPD). Studies of oxidative stress markers in South Asians were sparse. METHODS: One hundred and eighty COPD patients and eighty healthy nonsmokers were enrolled in the study. Serum malondialdehyde (MDA) and iron levels were estimated for oxidative stress. Three antioxidant markers evaluated-catalase, superoxide dismutase (SOD), and serum copper. Patients on antioxidant therapy and with sepsis and chronic illness were excluded from the study. RESULTS: The mean age of COPD patients was 59.29 ± 10.3 years. Serum levels of MDA and iron were significantly higher in COPD patients compared to controls (5.21 ± 1.9 vs. 0.71 ± 0.29 nmol MDA/ml, P = 0.0001 and 69.85 ± 85.49 vs. 79.32 ± 24.39 µg/dl, P = 0.0001, respectively). Mean level of all antioxidant enzymes catalase, SOD, and copper were significantly diminished in cases when compared to control population (P = 0.001). Levels of MDA and iron were found to be significantly elevated in higher Global Initiative for Chronic Obstructive Lung Disease (GOLD) classes (III, IV) when compared to lower GOLD Classes (I, II). The levels of serum antioxidants were significantly depleted in higher GOLD grades too. COPD patients who were male and smoked had significantly higher levels of oxidants and depleted antioxidant levels compared to female and nonsmoking compatriots. Serum MDA levels negatively correlated with forced expiratory volume 1 s and forced vital capacity (r = -0.19 and r = -0.21, P ≤ 0.01). The presence of a cough significantly correlated with higher levels of MDA and iron (P = 0.001). The levels of MDA negatively correlated with SOD and catalase levels. CONCLUSION: Oxidative markers (MDA and iron) are higher whereas antioxidants (catalase, copper, and SOD) are significantly reduced in patients of COPD. Serum MDA levels correlate with lung functions and disease severity.

Tip of nose tuberculosis: A rare presentation of extra pulmonary tuberculosis.

Tuberculosis is notorious that it affects various sites of the human body and presents in different ways. One of the uncommon or rather rare presentation of extra pulmonary tuberculosis is nasal tuberculosis. The nose apart from its physiological functions also contributes to facial aesthetics and gives a defined appearance and its deformity imparts cosmetic disfigurement and unsightly appearance. Both primary and secondary forms of nasal tuberculosis are rare but should be considered in the differential diagnosis of ulcerative or crusting lesions of the nose. Here we report such a case of nasal tuberculosis, which presented as an ulcerative and crusting lesion over the tip of the nose in a female child. The patient was given antituberculous chemotherapy after establishing the diagnosis and responded well to treatment.

Feasibility of transdermal delivery of fluoxetine.

Feasibility of developing a transdermal drug delivery of fluoxetine has been investigated. Permeation studies of fluoxetine across human cadaver skin were carried out using Franz diffusion cells. The receptor phase consisted of pH 7.4 phosphate buffer maintained at 37 degrees C. Permeation enhancement of fluoxetine, either in the salt or base form, was achieved using various enhancers like azone, SR-38, and ethanol. Various O/W microemulsion systems of fluoxetine were developed to study their effect on the skin permeation of fluoxetine. The results indicated that ethanol at 65% vol/vol was able to increase the permeation of fluoxetine the most, while microemulsion systems showed decrease in the permeation of fluoxetine. The permeation of fluoxetine obtained using a 65% vol/vol ethanolic solution was found to be sufficient to deliver the required dose (20-80 mg) from a patch of feasible size. The results seem promising for developing a transdermal drug delivery system of fluoxetine.

Assessing RNA interactions with proteins by DRaCALA.

Discovery of RNA elements, including riboswitches and regulatory RNAs, has revealed additional regulatory mechanisms for transcript stability, transcript termination, and translational initiation. These regulatory RNA molecules act through direct binding to cellular targets including other RNA molecules, proteins, and low molecular weight metabolites. RNA-RNA interactions based on complementarity can be identified through bioinformatic analysis. However, identification of novel interactions between these regulatory RNA molecules and their partners other than complementary sequences is more challenging. We have developed a technique called Differential Radial Capillary Action of Ligand Assay (DRaCALA) to facilitate the detection of direct binding between RNA elements to proteins or low molecular weight ligands. Previously, we have described the adaptation of this technique to detect the binding interaction between Vc2 riboswitch to a signaling cyclic dinucleotide called cyclic-di-GMP. Here, we describe the adaptation of DRaCALA for identifying sequence-specific RNA-binding proteins directly from E. coli cell lysates expressing the recombinant binding protein. DRaCALA can be used to qualitatively and quantitatively assess RNA-protein interaction in whole cell lysate, determine the kinetics of the binding, and test for competitors. Using DRaCALA in a high-throughput format has the potential to rapidly identify sequence-specific RNA-binding proteins.

Standardization of Gaja Puta and Ardha Gaja Puta in the preparation of Vanga Bhasma.

The Vanga Bhasma is an important one amongst the metallic Bhasmas. Mainly Gaja Puta, Ardhagaja Puta and Laghu Puta have been described for Marana of Vanga. The medicines, which are prepared from Gaja Puta, are said to be the best ones (Mahagunavidhayaka). Gaja Puta is commonly used in the preparation of almost all the Bhasmas. There are a few references found in classics regarding Ardhagaja Puta, but not any reference regarding its detail description, therefore, the effort was made to standardize both the Putas with regard to Vanga Bhasma. In the present study, Vanga Bhasma was prepared by Gaja Puta and Ardhagaja Puta. For Marana of Vanga, it was found that the Ardhagaja Puta is more convenient than Gaja Puta with respect to color and particle size analysis of Bhasma after Jarana procedure of Vanga.
