Keywords: Dust, heavy metal, peninsular Malaysia
Abstract: The dust samples of table fans and ceiling fans were collected from 30 sites including residential areas near cities and remote areas from Peninsular Malaysia. These dust samples were analysed for the concentrations of Cd, Cu, Ni, Pb and Zn. The Cd concentrations ranged from 2.48 to 20.76 ?g/g (mean:6.87+ 0.80?g/g) while the Cu concentrations ranged fro 27.12 to 3264 ?g/g (mean: 273.45 + 106.89 ?g/g). For Zn, they ranged from 101.84 to 1848 ?g/g (mean: 691.33+ 61.20 ?g/g). For Pb, they ranged from 165 to 843?g/g (mean: 464.01+ 30.89 ?g/g) while for Ni, they ranged from 16.8 to 1927 ?g/g (mean 117.11+ 62.65 ?g/g).The wide ranges of heavy metal concentrations in the dust samples indicated that they received varies sources of anthropogenic inputs including vehicular combustion, house cooking smokes, smokers ' smokes and industries. From the results obtained it can be concluded that the residential areas near major cities had the highest level of heavy metals. On the other hand, sites near forest and recreational areas were found to have low levels of heavy metals in the dust samples. This study signified the significant sources of heavy metal pollution due to anthropogenic sources namely vehicles and industrials. These findings are useful assessing the potential health hazards in humans.

Keywords: Lamellidens marginalis, chlorphyrifos, histology
Abstract: In the present study the freshwater mussel Lamellidens marginalis was exposed to sub-lethal concentration (5 ppm) of an organophosphorus insecticide, chlorphyrifos for 30 days. Mussel gill cells are attractive models in ecotoxicological studies because gills are the first uptake site for many toxicant in the aquatic environment; gill cells are thus often affected by exposure to pollutants. The gills of the mussels were dissected out and processed for light microscopy studies. Chlorpyrifos exposed mussels were found to result in several alterations in the histoarchitecture of gills. The alterations included: the bulging of primary filament gill tips, curling of secondary filament, fusion of gill lamellae, hyperplasia, necrotic and clavateglobate lamellae of the gills. The results suggest that the gills of mussels exposed to chorpyrifos were structurally altered. Such alterations could affect vital physicological functions, such as respiration, nutrient uptake and ionic regulation of the gills, which turn could ultimately affect the growth and survival of Lamellidens marginalis.

Keywords: Cadmium, RBD, WBC,Hemoglobin, Haematocrit
Abstract: Cadmium is designed as "The dissipated element" because of its potential for uncontrolled widespread introduction into the environment (Fulkerson et al., 1973). Cadmium toxicity depends on the dose, the route of administration, and duration of exposure. Cadmium causes renal failure by tubular and glomerular damages in kidney. This changes effects the alterations in RBC, WBC, Haematocrit and hemoglobin. The sub cutaneous injection of Wistar rats with 16 ?M cadmium chloride (CdCl2) leads to the significant increase levels of RBC (F=123.61), WBC (F=99.78), Haematocrit (F=248.33) and hemoglobin (10.871). The alterations in the blood indicate the hematotoxicity of cadmium.

Abstract: Nisin is an antimicrobial polypeptide produced by Lactococcus lactis and has been used internationally as a food preservative. However, purified nisin has become quite expensive in the current marketplace. Therefore, the study is directed to isolate Lactococcus lactis from raw milk and to produce nisin. Two multi-drug resistant strains of L. lactis isolated in the presence study were grown in four different media (MRS broth, Complex medium, BHI + 31% yeast extract medium and Skimmed milk medium) to produce nisin. Samples of nisin from these media were partially purified by employing 60% ammonium sulfate saturation and dialyzed through a membrane with a cut-off of 10,000 Da. The inhibitory effect of nisin and Listeria monocytogenes, Listeria ivanovii and Listeria grayi was studied by agar well diffusion assay. Nisin showed a significant inhibition against Listeria spp. tested. Nisin thus produced by L. lactis could be used as food preservative or the producer strian could be used as the starter culture in fermentation to inhibit the growth of Listeria spp., especially Listeria monocytogenes, which entes through post pasteurization contamination.

Abstract: Aloe vera is a semi tropical plant. It is a xerophytic medicinal plant and used worldwide in drug and cosmetic industry. Although, Aloe propagates vegetatively in its natural state, but production rate of aloe leaves is insufficient to meet demand of high quality planting material for commercial cultivation. A micro propagation method has been developed using shoot tip explants in Aloe vera. Shoot proliferation was initiated on MS medium containing different concentrations of BAP ranging from 0.5 mg/L to 2.5 mg/L. Maximum shoot proliferatio was achieved on medium containing BAP 1.0 mg/L within 25 days of culture. In case of rooting, MS medium containing NAA, IBA, IAA at different concentrations were used ranging from 0.1 mg/L to 2.0 mg/L. Combinations were also tried, MS medium containing NAA + IBA, NAA + IAA by varying concentrations of IBA, IAA (0.2 mg/L to 1.0 mg/L) with NAA as constant value of 0.2 mg/L. Optimum rooting was observed at 0.2 mg/L NAA. After transplanting the 45 days old rooted plants into various combinations of soil, survival rate was highest for Sand + coco pit + soil (1:1:2) and no of roots obtained were highest for sand + vermi compost + soil. Regenerated plants after hardening were transferred to soil and they showed 85% survival. The regenerated plants were morphologically similar to the mother plant.

Abstract: A study on the bioaccumulation of zinc, iron, copper, cadmium and aluminum by Chlorella vulgaris, Phacus curvicauda, Euglena acus and Oscillatoria bornettia was carried out for four weeks in the laboratory. There were highly significant correlations for some metals between concentrations in the algae and water; The concentration of Al in Phacus was significantly correlated to that in water; Fe, Cu and Al concentrations in Chlorella were significantly correlated to their concentrations present in water respectively; Fe concentration in Euglena was also signficantly correlated to that in water while Fe and Cd concentrations in Oscillatoria were significantly correlated to their concentrations present in water. Although, others had negative correlation coefficients but they were not significant (at p<0.05). A metal concentration factor was calculated for quantifying the metal removal potential of the test algae. Oscillatoria had the highest metal concentration factors for Zn (0.306), Fe (0.302), Cu (0.091) and Cd (0.276) while Phacus curvicauda and Euglena acus had the same and highest value for Al (0.439).

Abstract: The antifungal activity of the aqueous extracts of Allium sativum, methanolic and ethanolic extracts of Carica papaya and Vernonia amygdalina dried leaves against pure culture of Exophiala dermatitidis, Candida albican and Cryptococcus neoformans were studied. The growth of the organisms as determined by the agar well diffusion method, were inhibited by the aqueous extracts of the Allium sativum. The methanolic and ethanolic and aqueous extracts of Carica papaya and Vernonia amygdalina, how-ever, did not elicit visible inhibitory activity against the three test organisms. The minimum inhibitory concentration (MIC) of the aqueous extracts of Allium sativum on the organisms is 0.5 gm/L. This result suggests that aqueous extracts of Allium sativum may contain ingredients with therapeutic activity.

Abstract: Cadmium is a heavy metal which occurs in the nature in the form of various inorganic compounds and as complexes along with naturally occurring chelating agents. Heavy metals which are released by industries are immutable and non-biodegrable in nature. Among them, cadmium is one of the heavy metal which is used extensively in batteries, coating, electroplating and alloys. Although some cadmium-containing products can be recycled, a large share of the general cadmium pollution is caused by dumping and incineration of cadmium containing wastes. Cadmium is not only industrial pollutant but also found in ores with zinc, copper, and lead. 120 Male Wistar rats and divided in to two groups 10 animals as control Wistar rats (CWR) and the other 110 animals as cadmium chloride induced rats (CDIR). CWR group rats were received normal saline adn the CDIR group received cadmium chloride (10?M). After administration of 10 doses in 10 weeks, i.e., the total dose of the cadmium chloride reaches to 100?M. After 10 injections of cadmium chloride the tissues were collected by sacrificing the animal by cervical dislocation procedure and the cadmium concentration was estimated by using the Flame Atomic Absorption Spectrometry and it was observed in the order of Kidney>Testis>Pancreas>Spleen>Liver.
