The effect of two new chelating agents-Tiron (4,5-dihydroxy-1,3-benzene disulphonic acid disodium salt) and succinic acid--on the mobilization of beryllium was studied. Animals were exposed to beryllium nitrate (1 mg kg(-1) i.p.) daily for 21 days. Administration of beryllium nitrate showed a marked decrease in haemoglobin percentage, blood sugar, serum alkaline phosphatase and serum protein and a significant increase in the activity of transaminases. Tissue protein and glycogen contents and the activity of alkaline phosphatase, adenosine triphosphatase and succinic dehydrogenase showed significantly decreased values, but beryllium nitrate provoked a considerable increase in the activity of acid phosphatase and glucose-6-phosphatase in the vital and reproductive organs. Significant improvement in the haematological and biochemical parameters was observed with Tiron but no therapeutic effect was seen with succinic acid. Atomic absorption spectrophotometry (AAS) also showed a decreased level of beryllium concentration in the liver and kidney after Tiron therapy.

The efficacy of Tiron (4,5-dihydroxybenzene 1,3-disulfonic acid disodium salt) was examined in the treatment of beryllium-induced maternal and developmental toxicity in rats. Single administration of beryllium nitrate at a dose of 50 mg/kg (i.m.) on day 13 of gestation caused reductions in fetal and placental weights, the number of implantation sites and number of corpora lutea, as well as causing post-implantation loss, stunted growth, increase in the number of resorptions, and also a disturbed sex ratio. Maternal toxicity was demonstrated by reduction in body weight gain. Administration of beryllium also showed significant alteration in the hematological and biochemical indices of the mother as well as the fetus. Marked decreases were recorded in hemoglobin percentage, blood sugar levels, serum protein contents and serum alkaline phosphatase activity. By contrast, significant elevation was found in the activity of transaminases (aspartate aminotransferase and alanine aminotransferase). Tissue protein contents, glycogen contents, activities of alkaline phosphatase, adenosine triphosphatase and succinic dehydrogenase of kidney, lungs and uterus, and maternal and fetal liver all showed significantly decreased values after beryllium exposure, and remarkable elevation was observed in acid phosphatase, glucose-6-phosphatase and hepatic lipid peroxidation. These parameters were restored considerably with administration of 471 mg/kg i.m. Tiron from days 14 to 18 of gestation. Atomic absorption spectrophotometry also revealed a high concentration of beryllium in different organs of pregnant rats. Interestingly, a small amount of metal ion was also detected in the fetus and reduced accumulation of beryllium was noticed after Tiron treatment.

Protective effect of emodin (1,3,8-trihydroxy-6-methyl anthraquinone), an active compound of Ventilago madraspatana Gaertn., was evaluated against acetaminophen-induced biochemical and histological alterations in rats. Acetaminophen (2g/kg, po) administration caused significant elevation in the release of serum transaminases, alkaline phosphatase, lactate dehydrogenase, serum bilirubin and serum protein with concomitant decrease in hemoglobin and blood sugar after 24h of its administration. Toxicant exposure intensified the lipid peroxidation and altered glutathione status, activities of adenosine triphosphatase, acid phosphatase, alkaline phosphatase as well as major cellular constituents i.e., protein, glycogen and total cholesterol in liver and kidney. Treatment of emodin (20, 30 and 40 mg/kg, po) significantly lessened the toxicity by protecting acetaminophen-induced alterations in various blood and tissue biochemical variables after 24h of its administration. Acetaminophen administration initiated histological damage in liver. Some degree of protection was seen after emodin therapy in a dose-dependent manner. Emodin at doses of 30 and 40 mg/kg effectively reversed toxic events induced by acetaminophen as same as silymarin (50mg/kg, po). Thus, the study concluded that emodin at a dose of 30 mg/kg (po) possesses optimum hepatoprotective ability against acetaminophen-induced toxicity.

A 60-day experiment was carried out to study the effect of sub-lethal concentration of cypermethrin (1/10th of LC(50)) exposure on haematological and biochemical parameters of the Indian major carp, Catla catla fingerlings. Under exposure, the total erythrocyte count, total leucocyte count, haemoglobin content and haematocrit were decreased. All the studied serum parameters viz. total serum protein, albumin, globulin contents and albumin-globulin ratio were significantly decreased in cypermethrin-exposed fishes. A marked increase was recorded in alanine aminotransferase and aspartate aminotransferase activities in liver, whereas lactate dehydrogenase activity of muscle and acetylcholine esterase activity in brain were inhibited in cypermethrin-exposed fish. The membrane transport enzymes (total adenosine triphosphatase, sodium-potassium adenosine triphosphatase and magnesium adenosine triphosphatase) activities were decreased significantly in the gills of C. catla exposed to sub-lethal concentration of cypermethrin. The present study indicates that sub-lethal exposure of C. catla fingerlings to cypermethrin alters the haematological and biochemical parameters.
