Association of neutrophil gelatinase associated lipocalin, ischemia modified albumin with uric acid in the etiopathogenesis of preeclampsia.

OBJECTIVES: Preeclampsia is a multisystem illness that manifests in the third trimester of pregnancy after 20 weeks of gestation and is marked by proteinuria and hypertension (PE). Changes in lifestyle, such as eating a high-calorie diet and delaying delivery, have raised the likelihood of developing PE. Eclampsia, abrupt renal failure, thromboembolic episodes leading to cardiac and brain problems, pulmonary embolism, and coagulopathy associated with HELLP syndrome are a few of the complications that might follow preeclampsia in pregnant moms. The objects of this study is to estimate and correlate the levels of NGAL (neutrophil gelatinase associated lipocalin), IMA (ischemia modified albumin) and Uric acid in prreclampsia. METHODS: 40 diagnosed cases of preeclampsia and 40 healthy age and gestational age matched healthy controls were included in the study. Blood samples were collected from them and serum NGAL, IMA and Uric acid levels were estimated. Estimation of NGAL (neutrophil gelatinase associated lipocalin), IMA (ischemia modified albumin) was done by commercially available ELISA kits standard spectrophotometry methods in autoanalyzer Mind ray BS300 using commercially available kits. RESULTS: The parameters of NGAL and IMA were significantly increased in patients with PE (p<0.001) when compared with the healthy control subjects. γ-glutamyl transferases and OPN were found in patients with ALD (p<0.001) when compared with the control subjects. OPN showed significant positive correlations with AST (r=0.76, p<0.001), ALT (r=0.64 p<0.001), ALP (r=0.68, p<0.001), and GGT (r=0.61, p<0.001). CONCLUSIONS: The current study focuses on the roles of NGAL and IMA, two sensitive markers of kidney injury that are particularly useful in identifying widespread endothelial dysfunction. As a result, the pattern of elevated NGAL and IMA levels can be useful for diagnosis.

A study on serum homocysteine and oxidized LDL as markers of cardiovascular risk in patients with overt hypothyroidism.

OBJECTIVES: Hypothyroidism is the most common endocrine disorder worldwide. Hypothyroisim increases cardiovascular risk, thus the study focuses on the assessment of cardiovascular risk factors such as serum Homocysteine, serum Oxidized LDL and Lipid profile and their correlation with TSH levels. Timely evaluation of these risk predictors would help in reducing cardiovascular disease morbidity and mortality in hypothyroidism. METHODS: This was a hospital based cross-sectional study consisting of Forty newly diagnosed patients with overt hypothyroidism in the age group of 20-60 years attending Medicine OPD were included as cases and Fifty healthy age and gender matched healthy controls participated as controls in the study. A written and informed consent to all the participants of both the groups was taken after explaining the purpose and details of the study. The Thyroid profile was assessed by CLIA-based MAGLUMI- 1000 analyzer and Serum total cholesterol, triglycerides and high-density lipoproteins were analyzed in Fully automated clinical chemistry analyzer EM-200 by using commercially available kits. LDL was calculated indirectly using Friedwalds equation. Commercially available ELISA-based kits were used for analysis of serum Homocysteine and serum oxidized-LDL. RESULTS: Elevated levels of serum homocysteine (p<0.0001), Oxidized LDL (p<0.0001) were found in newly diagnosed overt hypothyroid patients as compared to controls whereas significant elevated levelsof TC, TG, LDL, and VLDL (p<0.0001) and decrease in HDLcholesterol (p<0.0001) were reported in newly diagnosed newly diagnosed overt hypothyroid patients. CONCLUSIONS: We concluded that the association of hyperhomocysteinemia and lipid abnormalities occurring in hypothyroidism may represent a dynamic atherogenic state and thyroid hormone failed to completely normalize Hcy levels. Thus, elevated plasma homocysteine levels may be an independent risk factor for the accelerated atherosclerosis seen in hypothyroidism. In addition, we found that the circulating ox-LDL levels were elevated in untreated hypothyroidism and they tend to be higher in thyroid dysfunction.

Vermiconversion of wastewater sludge from textile mill mixed with anaerobically digested biogas plant slurry employing Eisenia foetida.

Vermicomposting is commonly used for the management of organic wastes. We have investigated the potential of an epigeic earthworm, Eisenia foetida, to transform solid textile mill sludge (STMS) spiked with anaerobically digested biogas plant slurry (BPS) into vermicompost to evaluate the feasibility of vermicomposting in industries for waste management. The growth and reproduction of E. foetida was monitored in a range of different feed mixtures for 15 weeks in laboratory under controlled experimental conditions. E. foetida did not survive in fresh STMS. But worms grew and reproduced in STMS spiked with BPS feed mixtures. A greater percentage of STMS in feed mixture affected biomass gain and cocoon production by earthworms. The maximum growth was recorded in 100% BPS. The net weight gain by E. foetida in 100% BPS was two-four-fold higher than STMS-containing feed mixtures. After 15 weeks, maximum cocoons (78) were counted in 100% BPS and minimum (26) in 60% BPS+40% STMS feed. Vermicomposting resulted in pH shift toward acidic, significant reduction in C:N ratio, and increase in nitrogen, phosphorus, and potassium contents. Microbial activity measured as dehydrogenase activity increased with time up to day 75 but decreased on day 90, indicating the exhaustion of feed and decrease in microbial activity. These experiments demonstrate that vermicomposting can be an alternate technology for the recycling and environmentally safe disposal/management of textile mill sludge using an epigeic earthworm, E. foetida, if mixed with anaerobically digested BPS in appropriate ratios.

Effect of textile effluents on growth performance of wheat cultivars.

Laboratory experiments were conducted to study the effect of different concentrations in the range of 0-100% textile effluents (untreated and treated) on seed germination (%), delay index (DI), plant shoot length and root length, plant biomass, chlorophyll content and carotenoid of three different cultivars of wheat. The textile effluent did not show any inhibitory effect on seed germination at low concentration (6.25%). The other reported plant parameters also followed the similar trend. Seeds germinated in undiluted effluents did not survive for longer period. Based on the tolerance to textile effluent, the wheat cultivars have been arranged in the following order: PBW-343 < PBW-373 < WH-147. It has also been concluded that effect of the textile effluent is cultivar specific and due care should be taken before using the textile effluent for irrigation purpose.

Vermistabilization of textile mill sludge spiked with poultry droppings by an epigeic earthworm Eisenia foetida.

Investigations were made to explore the potential of an epigeic earthworm Eisenia foetida to transform textile mill sludge spiked with poultry droppings in to value added product, i.e., vermicompost. The growth and reproduction of E. foetida was monitored in a range of different feed mixtures for 77 days in the laboratory under controlled experimental conditions. The maximum growth was recorded in 100% cow dung (CD). Replacement of poultry droppings by cow dung in feed mixtures and vice versa had little or no effect on worm growth rate and reproduction potential. Worms grew and reproduced favourably in 70% poultry droppings (PD)+30% solid textile mill sludge (STMS) and 60% PD+40% STMS feed mixtures. Greater percentage of STMS in the feed mixture significantly affected the biomass gain and cocoon production. Net weight gain by earthworms in 100% CD was 2.9-18.2 fold higher than different STMS containing feed mixtures. The mean number of cocoon production was between 23.4+/-4.65 (in 100% CD) and 3.6+/-1.04 (in 50% PD+50% STMS) cocoons earthworm(-1) for different feed mixtures tested. Vermicomposting resulted in significant reduction in C:N ratio and increase in nitrogen and phosphorus contents. Total potassium, total calcium and heavy metals (Fe, Zn, Pb and Cd) contents were lower in the final product than initial feed mixtures. Our trials demonstrated vermicomposting as an alternate technology for the recycling and environmentally safe disposal/management of textile mill sludge using an epigeic earthworm E. foetida if mixed with poultry droppings.

Dynamics of biological and chemical parameters during vermicomposting of solid textile mill sludge mixed with cow dung and agricultural residues.

In India, thousands of tons of textile mill sludge are produced every year. We studied the ability of epigeic earthworm Eisenia foetida to transform textile mill sludge mixed with cow dung and/or agricultural residues into value added product, i.e., vermicompost. The growth, maturation, mortality, cocoon production, hatching success and the number of hatchlings were monitored in a range of different feed mixtures for 11 weeks in the laboratory under controlled environmental conditions. The maximum growth and reproduction was obtained in 100% cow dung, but worms grew and reproduced favorably in 80% cow dung + 20% solid textile mill sludge and 70% cow dung + 30% solid textile mill sludge also. Addition of agricultural residues had adverse effects on growth and reproduction of worms. Vermicomposting resulted in significant reduction in C:N ratio and increase in TKN, TP, TK and TCa after 77 days of worm activity in all the feeds. Vermicomposting can be an alternate technology for the management of textile mill sludge if mixed with cow dung in appropriate quantities.

Vermicomposting of mixed solid textile mill sludge and cow dung with the epigeic earthworm Eisenia foetida.

This paper reports the results of a study of vermicomposting with Eisenia foetida of solid textile mill sludge mixed with cow dung in different ratios in a 90 days composting experiment. Vermicomposting resulted in significant reduction in C:N ratio and increase in TKN. Total K and Ca were lower in the final cast than the initial feed mixture. Microbial activity measured as dehydrogenase activity increased up to 75 days and decreased on further incubation. Total P was higher in the final product than the initial feed mixture. Total heavy metal contents were lower in the final product than initial feed mixture. Solid textile mill sludge can be potentially useful as raw substrate in vermicomposting if mixed with up to 30% cow dung (on dry weight basis). The growth and cocoon production of the worm species in different feed mixtures were also investigated.
