ABSTRACT
Abstract The present study aimed to determine the effect of different levels of protein on the growth, body composition, amino acid profile and serology of Channa marulius fingerlings. The experiment was conducted in ten happas installed in earthen ponds, each stocked with 10 fishes for 90 days. Four commercial fish feeds having 25%, 30%, 32% and 40% crude protein (CP) levels were fed to fish at 3% of their wet body weight three times a day. The results of the study revealed that highest weight gain, feed conversion ratio and survival rate were observed in 30% protein feed. Meanwhile, moisture content was higher in fish fed with 30% CP feed while highest crude protein was recorded in 40% CP fed fish. Lowest fat content was observed in 32% CP feed. Amino acid profile of fish revealed better results in 30% CP feed. Total protein, glucose and globulin were also highest in fish feeding 30% CP feed, while albumin was highest in 40% CP feed. It is concluded that 30% CP feed showed better results in terms of growth, amino acid profile and serological parameters without effecting fish body composition.
Resumo O presente estudo teve como objetivo determinar o efeito de diferentes níveis de proteína sobre o crescimento, composição corporal, perfil de aminoácidos e sorologia de alevinos de Channa marulius. O experimento foi conduzido em dez happas instalados em tanques de terra, cada um abastecido com 10 peixes, por 90 dias. Quatro alimentos para peixes comerciais com níveis de 25%, 30%, 32% e 40% de proteína bruta (PB) foram dados aos peixes com 3% de seu peso corporal úmido três vezes ao dia. Os resultados do estudo revelaram que maior ganho de peso, taxa de conversão alimentar e taxa de sobrevivência foram observados em 30% de proteína alimentar. Enquanto isso, o conteúdo de umidade foi maior em peixes alimentados com 30% de PB, enquanto a proteína bruta mais alta foi registrada em peixes alimentados com 40% de PB. O menor conteúdo de gordura foi observado em rações com 32% de PB. O perfil de aminoácidos dos peixes revelou melhores resultados na ração com 30% de PB. Proteína total, glicose e globulina também foram maiores em peixes alimentados com ração com 30% de PB, enquanto a albumina foi mais alta com 40% de PB. Conclui-se que a ração com 30% de PB apresentou melhores resultados em termos de crescimento, perfil de aminoácidos e parâmetros sorológicos sem afetar a composição corporal dos peixes.
ABSTRACT
Abstract Growth of plants is severely reduced due to water stress by affecting photosynthesis including photosystem II (PSII) activity and electron transport. This study emphasised on comparative and priority targeted changes in PSII activity due to progressive drought in seven populations of Panicum antidotale (P. antidotale) collected from Cholistan Desert and non-Cholistan regions. Tillers of equal growth of seven populations of P. antidotale grown in plastic pots filled with soil were subjected progressive drought by withholding water irrigation for three weeks. Progressive drought reduced the soil moisture content, leaf relative water content, photosynthetic pigments and fresh and dry biomass of shoots in all seven populations. Populations from Dingarh Fort, Dingarh Grassland and Haiderwali had higher growth than those of other populations. Cholistani populations especially in Dingarh Grassland and Haiderwali had greater ability of osmotic adjustment as reflected by osmotic potential and greater accumulation of total soluble proteins. Maximum H2O2 under water stress was observed in populations from Muzaffargarh and Khanewal but these were intermediate in MDA content. Under water stress, populations from Muzaffargarh and Dingarh Fort had greater K+ accumulation in their leaves. During progressive drought, non-Cholistani populations showed complete leaf rolling after 23 days of drought, and these populations could not withstand with more water stress condition while Cholistani populations tolerated more water stress condition for 31 days. Moreover, progressive drought caused PSII damages after 19 days and it became severe after 23 days in non-Cholistani populations of P. antidotale than in Cholistani populations.
Resumo O crescimento das plantas é severamente reduzido devido ao estresse hídrico, afetando a fotossíntese, incluindo a atividade do fotossistema II (PSII) e o transporte de elétrons. Este estudo enfatizou as mudanças comparativas e prioritárias na atividade do PSII devido à seca progressiva em sete populações de Panicum antidotale (P. antidotale) coletadas no Deserto do Cholistão e regiões fora do Cholistão. Perfilhos de igual crescimento de sete populações de P. antidotale cultivadas em vasos de plástico cheios de solo foram submetidos à seca progressiva, retendo a irrigação com água por três semanas. A seca progressiva reduziu o teor de umidade do solo, teor de água relativo nas folhas, pigmentos fotossintéticos e biomassa fresca e seca dos brotos em todas as sete populações. Populações de Dingarh Fort, Dingarh Grassland e Haiderwali tiveram maior crescimento do que as de outras populações. As populações de Cholistani, especialmente em Dingarh Grassland e Haiderwali, apresentaram maior capacidade de ajuste osmótico, refletido pelo potencial osmótico e maior acúmulo de proteínas solúveis totais. H2O2 máximo sob estresse hídrico foi observado em populações de Muzaffargarh e Khanewal, mas estas foram intermediárias no conteúdo de MDA. Sob estresse hídrico, as populações de Muzaffargarh e Dingarh Fort tiveram maior acúmulo de K+ em suas folhas. Durante a seca progressiva, as populações não cholistanesas mostraram rolagem completa das folhas após 23 dias de seca, e essas populações não conseguiram suportar mais condições de estresse hídrico, enquanto as populações cholistani toleraram mais condições de estresse hídrico por 31 dias. Além disso, a seca progressiva causou danos ao PSII após 19 dias e tornou-se severa após 23 dias em populações não cholistanesas de P. antidotale do que em populações cholistanesas.

Background & objectives: The Government of India has initiated a population based screening (PBS) for noncommunicable diseases (NCDs). A health technology assessment agency in India commissioned a study to assess the cost-effectiveness of screening diabetes and hypertension. The present study was undertaken to estimate the cost of PBS for Type II diabetes and hypertension. Second, out-of-pocket expenditure (OOPE) for outpatient care and health-related quality of life (HRQoL) among diabetes and hypertension patients were estimated. Methods: Economic cost of PBS of diabetes and hypertension was assessed using micro-costing methodology from a health system perspective in two States. A total of 165 outpatients with diabetes, 300 with hypertension and 497 with both were recruited to collect data on OOPE and HRQoL. Results: On coverage of 50 per cent, the PBS of diabetes and hypertension incurred a cost of ? 45.2 per person screened. The mean OOPE on outpatient consultation for a patient with diabetes, hypertension and both diabetes and hypertension was ? 4381 (95% confidence interval [CI]: 3786-4976), ? 1427 (95% CI: 1278-1576) and ? 3932 (95% CI: 3614-4250), respectively. Catastrophic health expenditure was incurred by 20, 1.3 and 14.8 per cent of patients with diabetes, hypertension and both diabetes and hypertension, respectively. The mean HRQoL score of patients with diabetes, hypertension and both was 0.76 (95% CI: 0.72-0.8), 0.89 (95% CI: 0.87-0.91) and 0.68 (95% CI: 0.66-0.7), respectively. Interpretations & conclusions: The findings of our study are useful for assessing cost-effectiveness of screening strategies for diabetes and hypertension.
ABSTRACT
Background: Warts, the most common manifestation caused by human papillomaviruses. Treatment is needed because of risk of transmission, cosmetic point of view, multiple, painful, and disfigurement caused by warts. Aims and Objectives: In this study, two techniques of autologous therapy are compared in terms of safety and efficacy. Falknor’s needling and autoimplantation, both are minimally invasive procedures with the aim of treating one wart and inducing immunity against the viral infected cells. Materials and Methods: Forty patients of clinically diagnosed cutaneous warts were randomly divided into two groups. In Group A, Falknor’s needling was performed on a single lesion in each patient. In Group B, autoimplantation was done by harvesting a single lesion and then implanting the tissue in subcutaneous tissue of the patient at other body site. Results: Data were analyzed using SPSS software v. 23 (IBM Statistics, Chicago, USA) and Microsoft Office 2007. Both the modalities showed excellent response (P = 0.504) in the treatment of warts with Grade 4 improvement in 85% (17 patients each) in both the modalities, with 5% of the patients showing Grade 2 and Grade 3 improvement each in needling group. Conclusion: Both the modalities of autologous therapy are simple, easy to perform, safe, and cheap modalities with excellent results in the treatment of cutaneous warts.
ABSTRACT
Economic valuation of ecosystem services is a new concept in forest management. Economic valuation provides basis for payment for ecosystem services (PES). Therefore, objective of this study was to evaluate eco-tourism and carbon stock services of the Maindam valley, District Swat, Pakistan. For the carbon stock calculation, a sample size of 155 plots of 0.1 hectare (Ha) was taken using preliminary survey at 95% confidence interval and 10% allowable error. The data for tourism services was collected from owners of all the hotels, 100 tourists and key informants of the area at 10% sampling intensity on pretested questionnaire for twenty years period (1997-2017). Results showed that Miandam valley has carbon stock worth US$ 16,306,000 while the value of eco-tourism was US$ 1,578,458 on annual basis. The results also showed that trend of tourism has drastically declined after the 9/11 incident for foreigners and locals and the situation was further deteriorated during the era of Talibanization or militancy from 2008-2011. This study recommends implementation of PES strategy at the rate of 5%, thus a total of US$ 78,922 can be earned from eco-tourism and carbon crediting in the study area annually, which could play important role in sustainable forest management.
A valoração econômica dos serviços ecossistêmicos é um novo conceito no manejo florestal. A avaliação econômica fornece base para o pagamento por serviços ecossistêmicos (PES). Portanto, o objetivo deste estudo foi avaliar o ecoturismo e os serviços de estoque de carbono do vale de Miandam, distrito Swat, Paquistão. Para o cálculo do estoque de carbono, um tamanho de amostra de 155 parcelas de 0,1 hectare (ha) foi tirado, usando pesquisa preliminar com intervalo de confiança de 95% e erro admissível de 10%. Os dados para serviços de turismo foram coletados de proprietários de todos os hotéis, 100 turistas e informantes-chave da área em 10% de intensidade de amostragem em questionário pré-testado para um período de 20 anos (1997-2017). Os resultados mostraram que o vale de Miandam tem estoque de carbono no valor de US$ 16.306.000, enquanto o valor do ecoturismo foi de US$ 1.578.458 anualmente. Os resultados também mostraram que a tendência do turismo diminuiu drasticamente para estrangeiros e locais após o incidente de 11 de Setembro, e a situação se agravou ainda mais durante a era da talibanização ou militância de 2008-2011. Este estudo recomenda a implementação da estratégia de PES na taxa de 5%, portanto um total de US$ 78.922 pode ser ganho com ecoturismo e crédito de carbono na área de estudo anualmente, o que pode desempenhar um papel importante no manejo florestal sustentável.

Many soil microorganisms' i.e., bacteria and fungi produce secondary metabolites called antibiotics. These are used for the treatment of some of the bacterial, fungal and protozoal diseases of humans. There is a need for isolation of a broad spectrum of antibiotics from microorganisms due to the emergence of antibiotic resistance. In the present study two antibiotic producing bacteria Klebsiella pneumoniae and Bacillus cereus were isolated from pharmaceutical and poultry feed industry of Hattar, Haripur Pakistan. Total 10 waste samples were collected from different industries (Marble, Ghee, Soap, Mineral, Steel, Poultry Feed, Pharmaceutical, Qarshi, Cosmetic and Glass). Thirty-three bacterial strains were isolated from industrial wastes of these ten different industries. Fourteen out of thirty-three bacterial strains exhibited antimicrobial activities against at least one of the test microbes considered in this study including Escherchia coli, Staphylococcus aureus and Salmonella typhi. The bacteria were isolated by standard serial dilution spread plate technique. Morphological characterization of the isolates was done by Gram staining. Nine bacterial isolates out of fourteen were initially identified as B. cereus and five as K. pneumoniae through biochemical characterization. The antibacterial activities were tested by well diffusion method. Maximum number of antibiotic producing bacteria were isolated from pharmaceutical and poultry feed industry based on the results of primary screening, the most potential isolates S9, S19, S20, S22 and S23 were selected for secondary screening. The maximum activity against E. coli and S. aureus was recorded by bacterial isolate S19 i.e zones of inhibition of 6.5mm and 9mm while S20 showed 7.5mm and 6mm zones respectively. Molecular identification was carried out on the basis of 16S rRNA sequence [...].

The maximum activity against E. coli and S. aureus was recorded by bacterial isolate S19 i.e zones of inhibition of 6.5mm and 9mm while S20 showed 7.5mm and 6mm zones respectively. Molecular identification was carried out on the basis of 16S rRNA sequence analysis. Finally, the isolates were identified as B. cereus accession number LC538271and K. pneumoniae accession number MT078679. Analysis of bacterial extract S20 through GC-MS indicated the presence of 8 compounds of diverse nature and structure. Present study suggests that wastes of pharmaceutical and poultry feed industry may have antibiotic producing bacteria. These bacteria could be utilized for the production of antibiotics. B. cereus and K. pneumoniae isolated from wastes of poultry feed and pharmaceutical industries have the potential to produce antibiotics and could be used to control the microbial growth.

O número máximo de bactérias produtoras de antibióticos foi isolado da indústria farmacêutica e de ração avícola com base nos resultados da triagem primária, os isolados mais potenciais S9, S19, S20, S22 e S23 foram selecionados para a triagem secundária. A atividade máxima contra E. coli e S. aureus foi registrada pelo isolado bacteriano S19, ou seja, zonas de inibição de 6,5 mm e 9 mm, enquanto S20 mostrou zonas de 7,5 mm e 6 mm, respectivamente. A identificação molecular foi realizada com base na análise da sequência 16S rRNA. Finalmente, os isolados foram identificados como B. cereus número de acesso LC538271 e K. pneumoniae número de acesso MT078679. A análise do extrato bacteriano S20 por meio de GC-MS indicou a presença de oito compostos de natureza e estrutura diversas. O presente estudo sugere que resíduos da indústria farmacêutica e de ração para aves podem conter bactérias produtoras de antibióticos. Essas bactérias podem ser utilizadas para a produção de antibióticos B. cereus e K. pneumoniae isolados de resíduos de rações de aves e indústrias farmacêuticas têm potencial para produzir antibióticos e podem ser usados para controlar o crescimento microbiano.

Abstract Economic valuation of ecosystem services is a new concept in forest management. Economic valuation provides basis for payment for ecosystem services (PES). Therefore, objective of this study was to evaluate eco-tourism and carbon stock services of the Maindam valley, District Swat, Pakistan. For the carbon stock calculation, a sample size of 155 plots of 0.1 hectare (Ha) was taken using preliminary survey at 95% confidence interval and 10% allowable error. The data for tourism services was collected from owners of all the hotels, 100 tourists and key informants of the area at 10% sampling intensity on pretested questionnaire for twenty years period (1997-2017). Results showed that Miandam valley has carbon stock worth US$ 16,306,000 while the value of eco-tourism was US$ 1,578,458 on annual basis. The results also showed that trend of tourism has drastically declined after the 9/11 incident for foreigners and locals and the situation was further deteriorated during the era of Talibanization or militancy from 2008-2011. This study recommends implementation of PES strategy at the rate of 5%, thus a total of US$ 78,922 can be earned from eco-tourism and carbon crediting in the study area annually, which could play important role in sustainable forest management.
Resumo A valoração econômica dos serviços ecossistêmicos é um novo conceito no manejo florestal. A avaliação econômica fornece base para o pagamento por serviços ecossistêmicos (PES). Portanto, o objetivo deste estudo foi avaliar o ecoturismo e os serviços de estoque de carbono do vale de Miandam, distrito Swat, Paquistão. Para o cálculo do estoque de carbono, um tamanho de amostra de 155 parcelas de 0,1 hectare (ha) foi tirado, usando pesquisa preliminar com intervalo de confiança de 95% e erro admissível de 10%. Os dados para serviços de turismo foram coletados de proprietários de todos os hotéis, 100 turistas e informantes-chave da área em 10% de intensidade de amostragem em questionário pré-testado para um período de 20 anos (1997-2017). Os resultados mostraram que o vale de Miandam tem estoque de carbono no valor de US$ 16.306.000, enquanto o valor do ecoturismo foi de US$ 1.578.458 anualmente. Os resultados também mostraram que a tendência do turismo diminuiu drasticamente para estrangeiros e locais após o incidente de 11 de Setembro, e a situação se agravou ainda mais durante a era da talibanização ou militância de 2008-2011. Este estudo recomenda a implementação da estratégia de PES na taxa de 5%, portanto um total de US$ 78.922 pode ser ganho com ecoturismo e crédito de carbono na área de estudo anualmente, o que pode desempenhar um papel importante no manejo florestal sustentável.

Background: Warts are a common manifestation of infection due to HPV, prevalence more common in developing world. No modality is 100% efficacious in the management of warts. Topical therapy is more preferred method by majority of patients. Trichloroacetic acid (TCA) solution is well established modality in treatment of genital warts. Hydrogen peroxide used in higher concentrations is a good cautery agent. Aim and Objectives: The study was conducted to evaluate and compare the therapeutic efficacy and safety of 40% hydrogen peroxide solution and 80% TCA solution in genital warts. Materials and Methods: Topical 40% hydrogen peroxide and 80% TCA were used in Group A (20 patients) and Group B (20 patients), respectively, for three sittings at 2 weeks interval. Results: About 65% of the patients in TCA and 55% patients in H2O2 group had significant improvement (Grade 4 and Grade 3) (P = 0.311). Descriptive statistical methods and 2-Chi-square relation were used for analyzing data with Statistical Package for the Social Sciences (SPSS) 21 (SPSS Inc., Chicago, IL, USA). Results: About 40% H2O2 and 80% TCA, both are cost-effective and easy to use modalities with 40% H2O2 having better safety profile as compared to 80% TCA. H2O2 group showed decrease in size of lesions 63.33% versus and TCA group 70% (p value 0.311) with 10% of TCA group patients having ulcer formation versus none of the patients having significant adverse effect in H2O2 group. Conclusion: We found both the modalities to be safe and effective. However, we recommend further studies should be carried out to assess the safety and efficacy with bigger sample size and control arms for both the groups topical 40% hydrogen peroxide solution and topical 80% TCA solution.
ABSTRACT
Context: After introducing ‘Treat all policy’ in the country and free ART (Anti-retroviral therapy) for all patients the biggest challenge is to optimize adherence to therapy and ensure viral suppression. The present study is aimed to determine the adherence pattern of HIV positive patients at ART center, Jhansi in Uttar Pradesh and to determine the factors influencing adherence. Methods and Material: This cross-sectional study was conducted in an ART Centre of a teaching hospi-tal. In this study 357 patients were interviewed using a modified version of ACTG questionnaire and ad-herence was calculated by pill count and recall method. Chi square test and logistic regression was done using SPSS. Results: Nearly 72% patients had optimum adherence. On univariate analysis the factors found signifi-cant were sex of the patient, the education, the socioeconomic status, financial constraints, family sup-port, WHO stage at diagnosis, alcohol addiction and tobacco addiction. On logistic regression four factors, having less than college education, WHO stage IV at diagnosis, alcohol intake and lack of family support were found to be predictors of non-adherence. Conclusions: Family support, treatment of alcohol addiction improving education and job opportunities for these patients will improve adherence in HIV positive patients.
ABSTRACT
Background: Ayushman Bharat – Pradhan Mantri Jan Arogya Yojana has been launched to provide financial protection expenditure to nearly 500 million vulnerable Indians. For expanding the coverage under the scheme, it is necessary to understand the perspective of health care service providers involved in the scheme. Aim & Objective: To find out the bottlenecks in implementation of PMJAY scheme using empanelled hospitals’ perspective Settings and Design: Cross sectional study Methods and Material: 8 Public and 23 Private hospitals were selected through Simple Random Sampling from the list of PMJAY empanelled hospitals. The PMJAY Medical Officer co-ordinators in the empanelled hospitals were interviewed using a predesigned and pretested questionnaire. Statistical analysis used: Data was analysed using descriptive statistics in Epiinfo software. Results: Among the 31 empanelled hospitals studied, 93.5% were satisfied with the process for empanelment under PMJAY. 64.5% hospitals were not satisfied with the Health Benefit Packages. 77.4% hospitals perceived the PMJAY to be poorer as compared to private health insurance with reasons being poor grievance reprisal, poor claim processing and settlement, denial of reimbursement of health packages, poor rates of health packages and little information about the scheme. Conclusions: Various hurdles are being faced in the implementation of the scheme. There definitely remains a huge scope for further improvements so as to enhance the insurance coverage in the country.
ABSTRACT
Background: Infants and pre-school are most susceptible to undernutrition. Integrated Child Development Services is the programme focussing undernourished children by providing them supplementary nutrition. Aim& Objective: To study prevalence of undernutrition in 0-6 year old children and to study factors associated with it. To study impact of supplementary nutrition on undernourished children. Settings and Design: A longitudinal study. Methods and Material: The present longitudinal study was conducted in randomly selected Anganwadis of urban Meerut. Children found to be suffering from under nutrition were followed up at interval of six months to see the impact of supplementary nutrition provided to them at the anganwadi centre. A detailed history of relevant underlying factors responsible for causation of under nutrition were taken from mothers of these children. Statistical analysis used: chi square test was used to find out association between risk factors and undernutrition. Risk factor found statistically significant were further analysed using step wise multiple logistic regression analysis. The impact of supplementary nutrition was assessed using paired t test. Results: Iron folic acid supplementation during pregnancy, exclusive breast feeding in children, immunization and time of initiating complementary feed were found statistically significant on both chi-square and multiple logistic regression analysis. No impact of supplementary nutrition was found on anthropometric measurements of children. Conclusions: The main focus for fighting undernutrition in children (0-6 years) should be on preventing risk factors associated with mothers in antenatal period and during child rearing practices
ABSTRACT
We report on a 24 year old woman presented with low mood, reduced appetite, disturbed sleep and anxiety for which she was prescribed oral medication from a local practitioner in form of antidepressant(SSRI), anxiolytic(BZD) and upon no improvement, she underwent 8 rounds of successful electroconvulsive therapy (ECT) on which she responded partially and was discharged on SSRI. A few days after visited the same doctor and reported of having low mood, crying spells, referential and paranoid ideas and an attempt of suicide for which 10 more sessions of ECT were given. She presented in psychiatry OPD with catatonia where she was advised admission and diagnosed as a case of recurrent depressive disorder with catatonia and was managed with suprathreshold doses of SSRI and responded well.
ABSTRACT
Accumulation of metal in fish flesh is increasing because of heavy metal pollution in rivers of India, which poses significant threat to the consumers’ health. Here, we studied the concentrations of heavy metals [cadmium (Cd), chromium (Cr), copper (Cu), lead (Pb) and zinc (Zn)] in the muscle tissues of Banded or Striped gourami, Trichogaster fasciata Bloch & Schneider collected from the river Ganges and its tributaries in order to assess the risk the consumers are put to. The order of metal accumulation (Zn>Pb>Cu>Cr>Cd) was found to be the same in both the fish muscle and the water samples. Significant values of correlation of coefficient (R = 0.9184-0.9612) of length-weight relationship and mean condition factor ranging between 1.876-2.420 g/cm3 of different populations of the fish were recorded. All metal concentration was negatively correlated with the fish size and condition factor except Zn in Ghaghara and Yamuna (P <0.05) and Pb in the Ganges (P <0.05) and Yamuna (P <0.001). Estimated daily intakes by the fish-eating inhabitants were lower than the maximum tolerable daily intake value except for that of Zn. The target hazard quotient and health index showed that intake of these heavy metals was quite safe by the fish consuming local populations including both the male and females. This study could be used as an essential piece of information for the management purposes of river Ganga to prevent heavy metal pollution and risk associated with it.
ABSTRACT
Background: - COVID-19 is the most important public health problem of recent time. Many people require hospitalization after infection. COVID vaccination is the most effective way to prevent the disease. Due to extensive negative publicity through social media channels/platforms,significant number of individuals are not coming forward for vaccination. Therefore, study is needed to evaluate adverse effects associated with different vaccines available in India. Objectives: - To assess the adverse effects associated with COVID-19 vaccination and compare the side effect of two most commonly used COVID vaccines in India. Methods:- In the current report, a cross sectional study was conducted among beneficiaries of COVID-19 vaccines at the vaccination center of the LLRM Medical college, India. After institutional ethical clearance and informed consent, patients were asked about the symptoms they experienced after vaccination. A very simple random sampling approach was used to select beneficiaries. Information was collected on predesigned Google form and total 391 patients submitted the responses. Results:- Out of total respondents 77 % individuals reported one or more symptoms. Fever was reported to be most common problem (59.3%) followed by body ache (57.5%). Out of total beneficiaries, 68.3% experienced mild symptoms while 23% remain asymptomatic. Only few subjects reported moderate adverse effects (8.7%). None of the respondent reported severe and serious adverse effect. Conclusions:- Vaccine associated adverse effects were found less than 3 days and of mild variety in most of the beneficiaries. There was no difference in adverse effect profile of two commonly used vaccines in India. People must come forward for vaccination in mass without fearing of adverse effects of vaccines.
ABSTRACT
Abstract: Tissue culture technique is one of the best methods to reproduce salvia plant Therefore, the aim of this research was to enhance the in-vitro callus proliferation and production of secondary metabolites of S. moorcroftiana using different combinations of auxin, cytokinin and melatonin. Initially, callus induction was optimized using indole acetic acid (IAA), 2, 4-dichlorophenoxy acetic acid (2,4-D), and naphthalene acetic acid (NAA) applied at different concentrations in combination with 1 mg L-1 of 6-benzylaminopurine (BAP). The results indicates that earliest days to callus induction (14.67 days) was occurred in the media fortified with 2, 4-D+BAP (2.0+1.0 mgL-1). Whereas the highest callus initiation (100%) was induced on MS medium incorporated with 2,4-D+BAP (1+1mgL-1). Furthermore, maximum fresh weight was obtained when 2,4- D + BAP at the rate of (1+ 1mg L-1) was incorporated and dry weight was attained when 2,4- D + BAP at the rate of (2+1 mg L-1) was added to MS media. The maximum fresh and dry weight was obtained when melatonin at rate of 1.5 mg L-1 was supplemented with MS media including 2,4-D + BAP (1+1mg L-1), moreover the maximum DPPH scavenging activity, total phenolic and flavonoid content was noted when supplemented with melatonin at rate of 1.5 mg L-1. In conclusion, among various concentrations of plant growth regulators, 2,4- D + BAP at the rate of (1+ 1mg L-1) along with 1.5 g L-1 melatonin was the best for callus growth and production of secondary metabolites of S. moorcroftiana.
