Ameliorating Role of Lycopene, Tomato Puree, and Spirulina + Tomato Puree on the Hematology of Fluoride-Exposed Swiss Albino Mice.

Plant species rich in antioxidants (vitamins, flavonoids, lignans, and carotenoids) have been explored for complementary therapy of chronic diseases (cancers, coronary heart disease) and mitigation of pollutant toxicity. This article investigates their ameliorative role on selective hematological and serum biochemical parameters in fluoride-exposed (190 mg/kg body weight) Swiss albino mice pretreated with the antioxidant-rich diet supplements tomato puree (with and without peels), spirulina (cyanobacteria), and lycopene (present in tomato) for 45 days prior to entry into experimental protocol. Compared with standard feed control, diet-modulated controls had more hairy and lustrous white fur, hemodilution, increase in platelet counts (2- to 5-fold), red blood cell (RBC) size (11%-14%), mean corpuscular hemoglobin (Hb) concentration (MCHC; 5%-14%), and serum albumin (23%-27%).

Role of Spirulina in mitigating hemato-toxicity in Swiss albino mice exposed to aluminum and aluminum fluoride.

Aluminum is ingested through foods, water, air, and even drugs. Its intake is potentiated further through foods and tea prepared in aluminum utensils and Al salt added in the drinking water for removal of suspended impurities and also fluoride in the affected areas. The ameliorating role of a blue green alga Spirulina is well documented to various pollutants in the animal models.

Protective role of diet supplements Spirulina and Tamarind fruit pulp on kidney in sodium fluoride exposed Swiss albino mice: Histological and biochemical indices.

Fluoride toxicity through potable water, particularly ground water, is not uncommon in countries such as India, China, Iran, Iraq, Turkey, parts of Africa and Afghanistan. Kidney being the main organ involved in fluoride removal, it accumulates considerable amount of fluoride. Here, we report toxic effects of oral exposure of Swiss albino mice to fluoride (sub-acute: 190 mg/kg body wt.

Exploring fish bioassay of textile dye wastewaters and their selected constituents in terms of mortality and erythrocyte disorders.

Acute (4 day) and short-term (7 day) toxicity studies (at 1/5th and 1/10th of LC(50)) of textile dye wastewaters and their selected ingredients (azo dye methyl red and heavy metals Cd, Cu, Ni and Zn) were made on a freshwater fish Gambusia affinis under laboratory conditions. LC(50) value was found to be the lowest in four cases, and the EC(50) value for reduction in erythrocyte counts in the remaining four tests. Thus, the reduction in erythrocyte counts to the 50% level was similar in sensitivity to fish mortality.

Impact of distillery soil leachate on haematology of Swiss albino mice (Mus musculus).

This study reports significant alterations in various haematological parameters such as red and white blood corpuscles counts, haemoglobin content and packed cell volume in adult Swiss albino mice orally administered with diluted distillery soil leachate (5%-20%) for 30 days. Soil leachate also affected red blood cell morphology (poikilocytosis). The haematology of exposed mice improved in the reversal groups.

A comparative study on characterization of textile wastewaters (untreated and treated) toxicity by chemical and biological tests.

Toxicity of textile wastewaters (untreated and treated) and their ingredient chemicals was quantified in terms of their chemical characteristics, fish (Gambusia affinis) mortality and end point growth responses of duckweed (Lemna aequinoctialis) in short-term bioassays. Other parameters of fish bioassay were erythrocyte morphology and its counts. Despite of a definite correlation between data of biological tests (LC/EC(50) values) with that of chemical tests, biological tests were found to be relatively more sensitive to both wastewaters and ingredient chemicals.

A comparative study on the toxic effects of textile dye wastewaters (untreated and treated) on mortality and RBC of a freshwater fish Gambusia affinis (Baird and Gerard).

Comparative toxicological studies of textile dye wastewater (untreated and treated) on a freshwater fish, Gambusia affinis, revealed a marked reduction in mortality and cytotoxic effects on RBCs, measured as reduction in their counts and percent changes in their shape (poikilocytosis) and variation in their size (anisocytosis)}, after subjecting them to both physicochemical and biological treatments. On comparing the data of mortality and the cytotoxic effects on RBCs, we found poikilocytosis is a better indicator for toxicity measurement of both untreated as well as treated wastewater, especially at their lowest concentrations where percent mortality was found to be either nil or lowerer than the percentage of poikilocytic RBCs. Although percent reduction in RBC counts and changes in their size (anisocytosis) indicated toxic effects of wastewaters, but EC5o values for RBC counts were usually higher than those for poikilocytosis and mortality, and non-calculable for anisocytosis suggesting their lesser sensitivity to pollutants.

Identification of a sensitive index during fish bioassay of an azo dye methyl red (untreated and treated).

Acute and chronic toxicity of methyl red (untreated) was examined on a freshwater fish Poecilia reticulata, using indices viz; mortality, reduction in RBC counts and their morphological abnormality (poikilocytosis and anisocytosis). Similar studies (acute toxicity) were also made in physicochemically and biologically treated methyl red. Data comparison of these four indices revealed poikilocytosis as the most sensitive index, since it measured higher toxicity of methyl red when fish mortality was either minimum at its low concentration (5 ppm) during both acute and chronic toxicity or even nil in the biologically treated 100 ppm methyl red, during acute toxicity.

Effect of an acute and chronic toxicity of four commercial detergents on the freshwater fish Gambusia affinis Baird & Gerard.

The toxic effects of four commercial detergents (two washing powders and two cakes) are reported in this paper on behavior, mortality and RBC counts of a freshwater fish Gambusia affinis. During acute toxicity studies (96h), surface movements of fish increased markedly for 24h, only at higher concentrations (>10 ppm) of all the four detergents. Thereafter, they were lethargic and bottom dwellers similar to those exposed for a period of 30 days in the longterm ecotoxicological studies made on detergent powders at a sublethal concentration (10 ppm).

Protective role of Spirulina feed in a freshwater fish (Poecilia reticulata Peters) exposed to an azo dye-methyl red.

Acute toxicity of an azo dye-methyl red (5-40 ppm) was examined under starving conditions, on two groups of Poecilia reticulata--a freshwater fish, fed on different diets prior to their exposure to dye. Besides natural feed, fish of group-1 also received Spirulina feed for one month (feed population), whereas those of group-2 received only natural feed (non-feed population). The mortality data revealed non-feed population to be more tolerant to feed stress during acute toxicity study, whereas feed population exhibited better tolerance to the combined stress of both feed and methyl red; especially at higher concentrations of the latter.

Acute toxicity of textile dye wastewaters (untreated and treated) of Sanganer on male reproductive systems of albino rats and mice.

This study reports on the toxic effects of 15-days oral administration of untreated (Influent) and treated (Effluent) textile dye wastewaters on male reproductive systems of adult Swiss albino rats (age: 85-90 days) and mice (40-50 days). Textile dye wastewaters decreased body weight (7-25%) and reproductive organ weight (testis, epididymis, prostate gland and seminal vesicle, 2-48%). Similar trends were noted for total protein (14-70%), cholesterol (14-91%) and total lipid (10-30%) content of reproductive organs and spermatozoa, and for fructose levels in seminal vesicle (18-44%).

Certain haematological responses in Swiss albino mice following exposure to textile dye wastewater.

Adults Swiss mice were administered 5% solution of textile industry wastewater orally for 25 days and haematological parameters like RBC, WBC, Hb, and PCV were studied. Red cell indices like MCV, MCH and MCHC were calculated. Results indicate significant reduction in RBC, Hb and PCV levels.
