A Study on the Prevalence of Indoor Mycoflora in Air Conditioned Buses.

Aim: To study the presence of indoor mycoflora in A/c Buses to know the commuters risk of exposure to fungal spores. Place and Duration: Chennai Mofussil Bus Terminus (CMBT), Koyambedu, Chennai, India. Study was conducted from November 2011 to April 2012. Methodology: Airborne fungi from 50 A/c buses were studied using Reuter Centrifugal Sampler (Biotest, Germany), fungi from the surfaces of air vents through swab sample and bus seats by rubbing sterile petridishes on the seats. Sabourauds Dextrose Agar (SDA) was used for the isolation of fungi from different buses. The collected data were statistically analyzed. Results: A total of 38 species classified in 21 genera were recorded. Among which, Zygomycetes was represented by 4 species, Ascomycetes and Coelomycetes by single species each and the remaining belongs to Hyphomycetes. The genus, Aspergillus was represented by maximum number of species (11 species) followed by Penicillium (5 species). A total average of 713 CFU/m3 of air was recorded within the buses. Aspergillus niger was the first dominant fungi in the order of dominance followed by Chrysonilia sitophila, Alternaria alternata and Aspergillus flavus in that order. From the surface of bus seats, Aspergillus niger, A. flavus, Rhizopus stolonifer and A. japonicus were recorded as dominant. However, different mycofloral composition was recorded from air vents. Cladosporium chlorocephalum and Curvularia lunata dominated the surface of air vents. Conclusion: The study demonstrates the presence of potential fungal species which pose exposure risk to the immune compromised commuters.

Studies on Phytochemistry of 100 Plants in Chennai, India.

Aims: Knowledge on the plant phytochemistry provides a fundamental use of plants as a reservoir of chemical agents. Hence, the study on the presence of Phytochemicals in the aqueous extract of 100 different plant species belonging to 44 families collected from Chennai, India was detected. Place and Duration: Plants distributed in the Chennai district of Tamil Nadu state in India were studied. The study was conducted during the period of November 2012 to January 2013. Methods: Leaves of around 100 plant species belonging to different habit like trees, shrubs, herbs and creepers or climbers from Chennai and its surround districts of India were collected. The aqueous extract of air dried, pulverized leaf samples of collected plants were examined for the presence of Tannins, Phlobatannins, Saponins, Flavonoids, Terpenoids, Cardiac glycosides and Steroids using the standard techniques proposed by Evans (1996). The presence of individual secondary metabolites was calculated in percentage and their prevalence in different plant habit was studied. Results: Around 29%, 20%, 23%, 48%, 22%, 30% and 44% of plants showed the presence of Tannins, Phlobatannins, Saponins, Flavonoids, Terpenoids, Cardiac glycosides and Steroids in that order. Further, the presence of secondary metabolites according to the plant habit like, tree, shrub, herb and creeper or climber was detected. Conclusion: It was evident that the presence of Tannin, Phlobatannin, Flavonoids and Cardiac glycosides are found prevalent in trees, Steroids in herbs and Terpenoids in shrubs. However, further study on this aspect is recommended.

Genetic analysis of scattered populations of the Indian eri silkworm, Samia cynthia ricini Donovan: differentiation of subpopulations

Deforestation and exploitation has led to the fragmentation of habitats and scattering of populations of the economically important eri silkworm, Samia cynthia ricini, in north-east India. Genetic analysis of 15 eri populations, using ISSR markers, showed 98 percent inter-population, and 23 percent to 58 percent intra-population polymorphism. Nei's genetic distance between populations increased significantly with altitude (R² = 0.71) and geographic distance (R² = 0.78). On the dendrogram, the lower and upper Assam populations were clustered separately, with intermediate grouping of those from Barpathar and Chuchuyimlang, consistent with geographical distribution. The Nei's gene diversity index was 0.350 in total populations and 0.121 in subpopulations. The genetic differentiation estimate (Gst) was 0.276 among scattered populations. Neutrality tests showed deviation of 118 loci from Hardy-Weinberg equilibrium. The number of loci that deviated from neutrality increased with altitude (R² = 0.63). Test of linkage disequilibrium showed greater contribution of variance among eri subpopulations to total variance. D'2IS exceeded D'2ST, showed significant contribution of random genetic drift to the increase in variance of disequilibrium in subpopulations. In the Lakhimpur population, the peripheral part was separated from the core by a genetic distance of 0.260. Patchy habitats promoted low genetic variability, high linkage disequilibrium and colonization by new subpopulations. Increased gene flow and habitat-area expansion are required to maintain higher genetic variability and conservation of the original S. c. ricini gene pool.

Candidate genes for drought tolerance and improved productivity in rice (Oryza sativa L.).

Candidate genes are sequenced genes of known biological action involved in the development or physiology of a trait. Twenty-one putative candidate genes were designed after an exhaustive search in the public databases along with an elaborate literature survey for candidate gene products and/or regulatory sequences associated with enhanced drought resistance. The downloaded sequences were then used to design primers considering the flanking sequences as well. Polymerase chain reaction (PCR) performed on 10 diverse cultivars that involved Japonica, Indica and local accessions, revealed 12 polymorphic candidate genes. Seven polymorphic candidate genes were then utilized to genotype 148 individuals of CT9993 x IR62266 doubled haploid (DH) mapping population. The segregation data were tested for deviation from the expected Mendelian ratio (1:1) using a Chi-square test (less than 1%). Based on this, four candidate genes were assessed to be significant and the remaining three, as non-significant. All the significant candidate genes were biased towards CT9993, the female parent in the DH mapping population. Single-marker analysis strongly associated (less than 1%) them to different traits under both well-watered and low-moisture stress conditions. Two candidate genes, EXP15 and EXP13, were found to be associated with root number and silicon content in the stem respectively, under both well-watered and low-moisture stress conditions.

Chilaiditi syndrome with hypertension.

Chilaiditi syndrome is interposition of the intestine between liver and diaphragm. It is often asymptomatic but there were cases presented as acute pain in the abdomen, needing corrective surgical procedure; or as mistaken renal colic, or as suspected subphrenic abscess, or as pneumoperitonium. The interposition of proximal transverse colon was found to be more common than the small intestine. Chilaiditi syndrome was associated with colonic volvulus. The colonic interposition then progressed from mild abdominal discomfort to intermittent bowel obstruction. Some patients needed surgical operation like hepatic extraperitonealization, after replacement of the dislocated gastroenteric tract, bringing the superior surface of the liver again into direct contact with the related diaphragmatic dome. A rare case of Chilaiditi syndrome incidentally associated with hypertension and ischaemic heart disease, in a male aged 50 years is reported.

Granulocyte macrophage--colony stimulating factor (GM-CSF) as adjunct in induction therapy of acute myeloid leukemia.

Use of growth factors (G-CSF/GM-CSF) as adjunct in induction therapy of AML is controversial. Possible stimulation of leukemia cell clones has been the major cause of concern. We treated 50 cases of AML with GM-CSF as an adjunct during induction therapy. 35 patients (70%) achieved complete remission out of which 13 patients relapsed at a median relapse period of 15 months. Average duration of neutropenia was 10.5 days. (15 days in the control) Febrile episodes were fewer and antibiotic support was required for an average period of only 7.6 days (16.9 days in the control). The benefits including the economic analysis of the role of GM-CSF in this setting is discussed.

Effect of some beta-adrenoceptor blockers and of (+) propranolol on adrenaline-induced pulmonary edema in mice.

(+) Propranolol is considered to prevent adrenaline-induced pulmonary edema (A.P.E.) due to the beta-adrenoceptor blockade. However, local anaesthetics also are known to prevent pulmonary edema. To assess the role of beta-adrenergic blockade in A.P.E., the effect of a beta 1-blocker possessing local anaesthetic action (+/- Metaprolol) and a beta 1-blocker possessing no local anaesthetic action (+/- practolol) was studied along with propranolol derivatives. The study revealed that (+), (-), (+/-) propranolol and (+/-) metaprolol completely prevented A.P.E. whereas (+/-) practolol did not. This shows that local anaesthetic action but not the-beta adrenergic blockade may be responsible for prevention of A.P.E.
