Impact of untreated and Sargassum wightii-treated brilliant green dye exposure on Indian major carp, Labeo rohita Ham.: hematology, biochemistry, enzymology and histopathology.

Water pollution due to agricultural and industrial processes may cause adverse biological effects in aquatic organisms such as fishes. The removal of brilliant green (BG) dye from aqueous solution using seaweed Sargassum wightii was carried out. Further, it aimed to evaluate the exposure of BG dye activity on hematological, plasma biochemical, enzymological activities and histopathology of Indian major carp, Labeo rohita as a biomarker. High mortality rate (T2 65%) in the fishes exposed to untreated BG dye shows the toxic nature of the dye. Whereas fishes grown in treated BG dye showed less mortality rate (T3 25%) and (T1 30%) which depicts the less toxicity. The observed behavioral, biochemical, hematological and enzymological parameters were showed a significant increase in the treated BG dye. Extensive histopathological lesions in gill, liver and kidney tissues were observed in untreated BG dye compared to fishes grown in S. wightii-treated BG dye might be due to the stress caused by the toxic presence in the dye. The results concluded that S. wightii-treated BG dye does not have any inhibitory effect which reveals the nontoxic nature.

Kinetic studies on sorption of basic dye using Eichhornia crassipes.

Sorption capacity of different parts of Eichhornia crassipes, such as rhizome, root, lamina and petiole on basic aurophine-o was studied in a batch system. The equilibrium uptake capacity was observed as 13.65 mg/g (using root), 13.5 mg/g (using lamina), 12.9 mg/g (using rhizome) and 12.75 mg/g (using petiole). It was observed that the equilibrium dye uptake capacity using root was found to be more when compared to all other E. crassipes parts used in the present investigation. The shortcut equations developed are accurate and can be used in the place of experimental data. The shortcut equations form the basis for further research. The intra particle diffusion coefficient (K(i)) and effective diffusion coefficient (D(i)) were evaluated for the removal of dye using root, which were found to be more when compared to all other parts of E. crassipes studied such as, lamina, rhizome and petiole.

Accumulation of Acid Orange 7, Acid Red 18 and Reactive Black 5 by growing Schizophyllum commune.

The effect of Acid Orange 7, Acid Red 18 and Reactive Black 5 on the growth and decolorization properties of Schizophyllum commune was studied with respect to the initial pH varying from 1 to 6 and initial dye concentration (10-100 mg/L). The optimum pH value was found to be 2 for both growth and color removal of these azo dyes. Increasing the concentration of azo dyes inhibited the growth of S. commune. It was observed that S. commune was capable of removing Acid Orange 7, Acid Red 18 and Reactive Black 5 with a maximum specific uptake capacity of 44.23, 127.53 and 180.17 (mg/g) respectively for an initial concentration of 100 mg/L of the dye. Higher decolorization was observed at lower concentrations for all the dyes. Finally it was found that the percentage decolorization was more in the case of Reactive Black 5 dye compared to the other two dyes used in the present investigation.

Intramuscular administration of 15(S) methyl prostaglandins F2 alpha for midtrimester abortion.

PIP: This study evaluated the clinical efficacy, safety, and side effects of intramuscular administration of 15(S) methyl F2 alpha for midtrimester pregnancy termination. 25 healthy women, generally in the 14-6th weeks of pregnancy, were given repeated doses of 250 mcg of 15(S) followed by 300-600 mcg at 2-3 hour intervals, depending upon the uterine contractions and side effects. In addition, 15 women were given Lomotil tablets before prostaglandin administration to counteract gastrointestinal side effects. The mean required dosage of prostaglandin was 2.3 mg. The induction-abortion interval was 5-10 hours in 32%, 11-15 hours in 52%, 16-20 hours in 8%, and 21-25 hours in 8%, with a mean abortion time of 13.04 hours. 23 women (92%) has complete and spontaneous abortion. Women treated with Lomotil experienced fewer episodes of vomiting and diarrhea. Other side effects included nausea in 40% of cases, cough in 12%, and fever in 16%. These side effects were mild and well tolerated by the patients, however. It is concluded that serial intramuscular injection of prostaglandin 15(S) methyl F2 alpha is an effective method for midtrimester abortion. In view of the minimal blood loss and asepsis associated with this method, it is particularly suitable for centers where blood transfusion facilities are inadequate.^ieng
