When garlic (Allium sativum) was administered to rat per os simultaneously with cadmium, methylmercury and phenylmercury to detect the protective effect against the heavy metal poisoning, accumulation of heavy metals in liver, kidneys, bone and testes were decreased, and histopathological damages and the inhibition of serum alkaline phosphatase activities by heavy metals were reduced. Such effect of garlic was not shown in the 1.7% garlic treated group and most remarkable in the 6.7% garlic treated group. The protective effect of garlic was superior to those of 2,3 dimercapto-1-propanol (BAL) and D-penicillamine (PEN), and nearly similar to those of 2,3-dimercaptosuccinic acid (DMSA) and N-acetyl-DL-penicillamine (APEN), the current remedies, while garlic was not effective as a curative agent for heavy metal poisoning. The excretion of cadmium was enhanced, more through feces than urine by garlic but the effect to the urinary excretion of cadmium was not significant comparing with DMSA or APEN when cadmium was ip injected in the first 3 days during the 12 days of oral administration of DMSA, APEN or garlic.

The effect of tetrathiomolybdate (TM), disodium calcium ethylenediamine tetraacetate (EDTA), D-penicillamine (PEN), 2-3 dimercapto-1-propanol (BAL) and dimethyl dithiocarbamate (DDC) administration on biliary and urinary excretion of copper (Cu), zinc (Zn) and iron (Fe) was investigated in sheep on a low Cu diet (Group A) and a high Cu diet (Group B). Only biliary Cu excretion increased significantly (P<0.01) with TM treatment. Urinary Cu excretion increased (P<0.01) following PEN treatment. TM, EDTA, PEN, BAL and DDC adminstration increased Cu excretion via bile and urine by 254, 11, 266, 46 and 16%, respectively in Group A sheep, and by 354, 13, 196, 20 and (-) 31% in Group B sheep. Urinary Zn excretion increased (P<0.01) following EDTA and PEN treatments. Only urinary Fe excretion increased (P<0.01) with EDTA treatment. The results show that TM and PEN are the most efficient decoppering agents, but PEN unlike TM also removes Zn. The major routes of excretion of Cu chelates by TM and PEN are different. TM increases Cu excretion significantly (P<0.05 in Group A and P<0.01 in Group B) in bile with only a slight increase in urinary Cu whereas PEN increases Cu excretion significantly (P<0.01) in urine. Therefore from a therapeutic view, a combination therapy of TM and PEN would be useful to maximize Cu removal from the body.

A 2:1 molar ratio preparation of bismuth with a lipophilic dithiol (3-dimercapto-1-propanol, BAL) significantly reduced extracellular polymeric substances (EPS) expression by Brevundimonas diminuta in suspended cultures at levels just below the minimum inhibitory concentration (MIC). Total polysaccharides and proteins secreted by B. diminuta decreased by approximately 95% over a 5-day period when exposed to the bismuth-BAL chelate (BisBAL) at near MIC (12 microM). Fourier-transform infrared spectroscopy (FTIR) suggested that a possible mechanism of biofilm disruption by BisBAL is the inhibition of carbohydrate O-acetylation. FTIR also revealed extensive homology between EPS samples with and without BisBAL treatment, with proteins, polysaccharides, and peptides varying predominantly only in the amount expressed. EPS secretion decreased following BisBAL treatment as verified by atomic force microscopy and scanning electron microscopy. Without BisBAL treatment, a slime-like EPS matrix secreted by B. diminuta resulted in biofouling and inefficient hydrodynamic backwashing of microfiltration membranes.

A sequential analytical method was developed for the detection of arsenite, arsenate, and methylarsenate in human urine by gas chromatography-mass spectrometry (GC-MS). The combination of a derivatization of trivalent arsenic compounds by 2,3-dithio-1-propanol (British antilewisite; BAL) and a reduction of pentavalent arsenic compounds (arsenate and methylarsenate) were accomplished to carry out the analysis of arsenic compounds in urine. The arsenic derivatives obtained using BAL were extracted in a stepwise manner using a monolithic spin column and analyzed by GC-MS. A linear curve was observed for concentrations of arsenic compounds of 2.0 to 200 ng/mL, where the correlation coefficients of calibration curves were greater than 0.996 (for a signal-to-noise (S/N) ratio >10). The detection limits were 1 ng/mL (S/N > 3). Recoveries of the targets in urine were in the range 91.9-106.5%, and RSDs of the intra- and interday assay for urine samples containing 5, 50, and 150 ng/mL of arsenic compounds varied between 2.95 and 13.4%. The results from real samples obtained from a patient suspected of having ingested As containing medications using this proposed method were in good agreement with those obtained using high-performance liquid chromatography with inductively coupled plasma mass spectrometry.
