This study aimed to evaluate the toxicity of Cladophora glomerata and Microspora floccosa ethanolic extracts in rats. Acute toxicity was tested with a single oral administration of the extract at a dose of 25 g/kg bd wt. Mortality, behavior, amount of food intake, body weight, and any abnormalities of the visceral organs, were observed. The results showed that the extract caused neither mortali...

Many fishes are ammonotelic but some species can detoxify ammonia to glutamine or urea. Certain fish species can accumulate high levels of ammonia in the brain or defense against ammonia toxicity by enhancing the effectiveness of ammonia excretion through active NH4+transport, manipulation of ambient pH, or reduction in ammonia permeability through the branchial and cutaneous epithelia. Recent ...

Background: The activity and toxicity of etoposide in women with recurrent ovarian cancer was evaluated in a case series of women with recurrent ovarian cancer who had measurable disease, Methods: All patients had plior platinum-based chemotherapy and developed progressive disease, Etoposide was given as 50mg/day for 21 days every 4 weeks until progression of disease or prohibitive toxicit...

Maridomycin, a new macrolide antibiotic, and tetrahydromaridomycin were acylated into their mono, di, and tri acyl derivatives. These derivatives were compared with the parent antibiotic, maridomycin, for their (i) in vitro antimicrobial activities, (ii) protective effect in mice infected with Staphylococcus aureus (oral administration), (iii) blood levels attained in rats, and (iv) acute toxic...

In continuation of our short-term pilot studies reported earlier, results on certain toxicity biomarkers in volunteers who continued to take the potentized Arsenicum album 200C till 2 years are presented. Out of some 130 "verum"-fed volunteers of pilot study, 96 continued to take the remedy till 6 months, 65 till 1 year and 15 among them continued till 2 years. They provided samples of their ur...

Treatment of head and neck squamous cell carcinoma (HNSCC) by chemoradiotherapy (CRT) often results in high-grade acute organ toxicity (HGAOT). As these adverse effects impair the patients' quality of life and the feasibility of the planned therapy, we sought to analyze immunological parameters in tumor material and blood samples obtained from 48 HNSCC patients in order to assess the potential ...

The present investigation was aimed at studying the possible role of curcumin against N-nitrosodiethylamine (NDEA)-induced toxicity in albino rats. Administration of NDEA to rats at a concentration of 0.1 mg/ml in drinking water ad libitum for 21 days produced toxicity in them, which was evident from histopathological changes in the rat livers, and increased levels of blood serum enzyme markers...

A better understanding of the mechanism(s) of cell mediated toxicity for colon cells in vitro may help clarify the pathogenesis of inflammatory bowel disease (IBD). We have examined both the cytotoxicity of IBD peripheral blood mononuclear cells and the kinetics of induction of such toxicity by soluble plasma factors. Peripheral blood mononuclear cells from IBD patients were found to be cytotox...

to be the same. However, since some samples of blood stored in ACDI in the present study did give satisfactory survival results at 35 and 42 days, it has been suggested that red cells of different individuals may vary in their ability to withstand prolonged storage. It should be noted that the purine nucleosides are metabolized to uric acid. While in healthy volunteers the transfusion of450 ml ...
