MARKET SAMPLE SURVEY OF CROCUS SATIVUS LINN. TO ASSESS THE GENUINITY FOR USING ANTIOXIDANT ACTIVITY, TOTAL PHENOLIC CONTENT AND HIGH-PRESSURE THIN LAYER CHROMATOGRAPHY USING DETECTION OF FLAVONOIDS

Objective: Herbalism is a traditional medicine or folk medicine practice based on the use of plants and plant extracts. Many of the drugs used in conventional medicine are dried from herbs. Despite the fluctuation in prices in international markets, saffron was still remained the most expensive spice. The main aim of this study is to examine the antioxidant activity, total phenolic content, high-pressure thin layer chromatography using flavanoid analysis and adulteration detection of saffron. Crocus sativus. Linn is a perennial stemless herb of the Iridaceae family. Saffron stigmas of sample1, sample2, sample3and sample4 are collected from different rates of the market sample from Thrissur district, sample5 collected from the Oushadhi premises, and it is collected from Himachal Pradesh. Methods: In this study detecting the antioxidant activity, total phenolic content, high-pressure thin layer chromatography using flavanoid analysis of different samples of saffron stigmas. The extracts were prepared by using ethanol as a solvent. Results: Safranal is present only in s5 sample. It is the main essential volatile oil responsible for the saffron characteristic such as odour. Phenolic content is varied in different market samples. The amount of phenolic compounds in the saffron extract was determined using the Folin-ciocalteau reagent. Total phenolic content is the help to detect the pure and fake saffron. The phenolic content is higher in S5. Sample S5 showed 0.737 mg/ml phenolic content. Lowest level of phenolic content in sample S3. Sample S3 showed 0.0887 mg/ml phenolic content. Sample S4 showed 0.564 mg/ml total phenolic content. Sample S1 showed 0.416 mg/ml total phenolic content and sample S2 showed 0.267 mg/ml phenolic content. Antioxidant activity is higher in sample s5. and it is different in different market samples. Sample 5 stigma posses higher antioxidant activity. Sample S5 showing 14.88% antioxidant activity in 100 mg/ml concentration, 7.26% in 80 mg/ml concentration, 2.23% in 60 mg/ml concentration, 2.21% in 40 mg/ml and 1.01% in 20 mg/ml concentration. Sample S3 showed the lower antioxidant activity in 0.1% in 60 mg/ml concentration and 0.1% in 80 mg/ml. Ascorbic acid standard showing 14.89% in 100 mg/ml concentration, 7.26% in 80 mg/ml concentration, 4.56% in 60 mg/ml concentration, and 3.1% in 40 mg/ml concentration, and 1% in 20 mg/ml concentration. Flavonoid content is different in different samples. It is present highly present in sample s1 and s5. sample s3 do not contain the Flavanoid. The quality of the samples depend on the price values. Conclusion: The authenticity of saffron is an extremely important matter for the industry and for the consumers in view of security and protection,quality assurance, active properties and last but not least, economic impact. Despite the fluctuation in prices in international markets, saffron was and still remains the most expensive spice. The genuine saffron samples possess higher price value. The fake saffron available in the market with lower price value. The quality of the saffron depends upon the price values. These observations would be of immense value in the botanical identification and standardization of the drug in crude form and would help to distinguish the drug from its other spices

Home delivery and newborn care practices among urban women in western Nepal: a questionnaire survey

BACKGROUND: About 98% of newborn deaths occur in developing countries, where most newborns deaths occur at home. In Nepal, approximately, 90% of deliveries take place at home. Information about reasons for delivering at home and newborn care practices in urban areas of Nepal is lacking and such information will be useful for policy makers. METHODS: A cross-sectional survey was carried out in the immunisation clinics of Pokhara city, western Nepal during January and February, 2006. Two trained health workers administered a semi-structured questionnaire to the mothers who had delivered at home. RESULTS: A total of 240 mothers were interviewed. Planned home deliveries were 140 (58.3%) and 100 (41.7%) were unplanned. Only 6.2% of deliveries had a skilled birth attendant present and 38 (15.8%) mothers gave birth alone. Only 46 (16.2%) women had used a clean home delivery kit and only 92 (38.3%) birth attendants had washed their hands. The umbilical cord was cut after expulsion of placenta in 154 (64.2%) deliveries and cord was cut using a new/boiled blade in 217 (90.4%) deliveries. Mustard oil was applied to the umbilical cord in 53 (22.1%) deliveries. Birth place was heated throughout the delivery in 88 (64.2%) deliveries. Only 100 (45.8%) newborns were wrapped within 10 minutes and 233 (97.1%) were wrapped within 30 minutes. Majority (93.8%) of the newborns were given a bath soon after birth. Mustard oil massage of the newborns was a common practice (144, 60%). Sixteen (10.8%) mothers did not feed colostrum to their babies. Prelacteal feeds were given to 37(15.2%) newborns. Initiation rates of breast-feeding were 57.9% within one hour and 85.4% within 24 hours. Main reasons cited for delivering at home were 'preference' (25.7%), 'ease and convenience' (21.4%) for planned deliveries while 'precipitate labor' (51%), 'lack of transportation' (18%) and 'lack of escort' during labor (11%) were cited for the unplanned ones. CONCLUSION: High-risk home delivery and newborn care practices are common in urban population also. In-depth qualitative studies are needed to explore the reasons for delivering at home. Community-based interventions are required to improve the number of families engaging a skilled attendant and hygiene during delivery. The high-risk traditional newborn care practices like delayed wrapping, bathing, mustard oil massage, prelacteal feeding and discarding colostrum need to be addressed by culturally acceptable community-based health education programmes

Care seeking behaviour for childhood illness- a questionnaire survey in western Nepal

BACKGROUND: The World Health Organization estimates that seeking prompt and appropriate care could reduce child deaths due to acute respiratory infections by 20%. The purpose of our study was to assess care seeking behaviour of the mothers during childhood illness and to determine the predictors of mother's care seeking behaviour. METHODS: A cross-sectional survey was conducted in the immunization clinics of Pokhara city, Kaski district, western Nepal. A trained health worker interviewed the mothers of children suffering from illness during the preceding 15 days. RESULTS: A total of 292 mothers were interviewed. Pharmacies (46.2%) were the most common facilities where care was sought followed by allopathic medical practitioners (26.4%). No care was sought for 8 (2.7%) children and 26 (8.9%) children received traditional/home remedies. 'Appropriate', 'prompt' and 'appropriate and prompt' care was sought by 77 (26.4%), 166 (56.8%) and 33 (11.3%) mothers respectively. The mothers were aware of fever (51%), child becoming sicker (45.2%) and drinking poorly (42.5%) as the danger signs of childhood illness. By multiple logistic regression analysis total family income, number of symptoms, mothers' education and perceived severity of illness were the predictors of care seeking behaviour. CONCLUSION: The results of the present study show that the mothers were more likely to seek care when they perceived the illness as 'serious'. Poor maternal knowledge of danger signs of childhood illness warrants the need for a complementary introduction of community-based Integrated Management of Childhood Illness programmes to improve family's care seeking behaviour and their ability to recognize danger signs of childhood illness. Socioeconomic development of the urban poor may overcome their financial constraints to seek 'appropriate' and 'prompt' care during the childhood illness

Human Metapneumovirus in Turkey Poults

This study was conducted to reexamine the hypothesis that human metapneumovirus (hMPV) will not infect turkeys. Six groups of 2-week-old turkeys (20 per group) were inoculated oculonasally with 1 of the following: noninfected cell suspension; hMPV genotype A1, A2, B1, or B2; or avian metapneumovirus (aMPV) subtype C. Poults inoculated with hMPV showed nasal discharge days 4–9 postexposure. Specific viral RNA and antigen were detected by reverse-transcription PCR and immunohistochemical evaluation, respectively, in nasal turbinates of birds exposed to hMPV. Nasal turbinates of hMPV-infected turkeys showed inflammatory changes and mucus accumulation. Each of the 4 hMPV genotypes caused a transient infection in turkeys as evidenced by clinical signs, detection of hMPV in turbinates, and histopathologic examination. Detailed investigation of cross-species pathogenicity of hMPV and aMPV and its importance for human and animal health is needed

Shallow water marine sediment bacterial community shifts along a natural CO2 gradient in the Mediterranean Sea off Vulcano, Italy.

The effects of increasing atmospheric CO(2) on ocean ecosystems are a major environmental concern, as rapid shoaling of the carbonate saturation horizon is exposing vast areas of marine sediments to corrosive waters worldwide. Natural CO(2) gradients off Vulcano, Italy, have revealed profound ecosystem changes along rocky shore habitats as carbonate saturation levels decrease, but no investigations have yet been made of the sedimentary habitat. Here, we sampled the upper 2 cm of volcanic sand in three zones, ambient (median pCO(2) 419 μatm, minimum Ω(arag) 3.77), moderately CO(2)-enriched (median pCO(2) 592 μatm, minimum Ω(arag) 2.96), and highly CO(2)-enriched (median pCO(2) 1611 μatm, minimum Ω(arag) 0.35). We tested the hypothesis that increasing levels of seawater pCO(2) would cause significant shifts in sediment bacterial community composition, as shown recently in epilithic biofilms at the study site. In this study, 454 pyrosequencing of the V1 to V3 region of the 16S rRNA gene revealed a shift in community composition with increasing pCO(2). The relative abundances of most of the dominant genera were unaffected by the pCO(2) gradient, although there were significant differences for some 5 % of the genera present (viz. Georgenia, Lutibacter, Photobacterium, Acinetobacter, and Paenibacillus), and Shannon Diversity was greatest in sediments subject to long-term acidification (>100 years). Overall, this supports the view that globally increased ocean pCO(2) will be associated with changes in sediment bacterial community composition but that most of these organisms are resilient. However, further work is required to assess whether these results apply to other types of coastal sediments and whether the changes in relative abundance of bacterial taxa that we observed can significantly alter the biogeochemical functions of marine sediments

Glycoprotein gene truncation in avian metapneumovirus subtype C isolates from the United States

The length of the published glycoprotein (G) gene sequences of avian metapneumovirus subtype-C (aMPV-C) isolated from domestic turkeys and wild birds in the United States (1996–2003) remains controversial. To explore the G gene size variation in aMPV-C by the year of isolation and cell culture passage levels, we examined 21 turkey isolates of aMPV-C at different cell culture passages. The early domestic turkey isolates of aMPV-C (aMPV/CO/1996, aMPV/MN/1a-b, and 2a-b/97) had a G gene of 1,798 nucleotides (nt) that coded for a predicted protein of 585 amino acids (aa) and showed >97% nt similarity with that of aMPV-C isolated from Canada geese. This large G gene got truncated upon serial passages in Vero cell cultures by deletion of 1,015 nt near the end of the open reading frame. The recent domestic turkey isolates of aMPV-C lacked the large G gene but instead had a small G gene of 783 nt, irrespective of cell culture passage levels. In some cultures, both large and small genes were detected, indicating the existence of a mixed population of the virus. Apparently, serial passage of aMPV-C in cell cultures and natural passage in turkeys in the field led to truncation of the G gene, which may be a mechanism of virus evolution for survival in a new host or environment

International nosocomial infection control consortium (INICC) report, data summary of 36 countries, for 2004-2009

The results of a surveillance study conducted by the International Nosocomial Infection Control Consortium (INICC) from January 2004 through December 2009 in 422 intensive care units (ICUs) of 36 countries in Latin America, Asia, Africa, and Europe are reported. During the 6-year study period, using Centers for Disease Control and Prevention (CDC) National Healthcare Safety Network (NHSN; formerly the National Nosocomial Infection Surveillance system [NNIS]) definitions for device-associated health care-associated infections, we gathered prospective data from 313,008 patients hospitalized in the consortium's ICUs for an aggregate of 2,194,897 ICU bed-days. Despite the fact that the use of devices in the developing countries' ICUs was remarkably similar to that reported in US ICUs in the CDC's NHSN, rates of device-associated nosocomial infection were significantly higher in the ICUs of the INICC hospitals; the pooled rate of central line-associated bloodstream infection in the INICC ICUs of 6.8 per 1,000 central line-days was more than 3-fold higher than the 2.0 per 1,000 central line-days reported in comparable US ICUs. The overall rate of ventilator-associated pneumonia also was far higher (15.8 vs 3.3 per 1,000 ventilator-days), as was the rate of catheter-associated urinary tract infection (6.3 vs. 3.3 per 1,000 catheter-days). Notably, the frequencies of resistance of Pseudomonas aeruginosa isolates to imipenem (47.2% vs 23.0%), Klebsiella pneumoniae isolates to ceftazidime (76.3% vs 27.1%), Escherichia coli isolates to ceftazidime (66.7% vs 8.1%), Staphylococcus aureus isolates to methicillin (84.4% vs 56.8%), were also higher in the consortium's ICUs, and the crude unadjusted excess mortalities of device-related infections ranged from 7.3% (for catheter-associated urinary tract infection) to 15.2% (for ventilator-associated pneumonia).
