Intraperitoneal gelatin sponge implants were used in guinea-pigs to examine the effect of D-penicillamine on the delayed hypersensitivity reaction in vivo. When it was administered daily in a dose of 200 mg/kg for 14 days before sensitisation or for 14 or 30 days before challenge, D-penicillamine increased the number of exudate cells during the onset of the delayed hypersensitivity reaction. Ab...

PURPOSE (64)Cu-diacetyl-bis (N (4)-methylthiosemicarbazone) ((64)Cu-ATSM) is a promising theranostic agent that targets hypoxic regions in tumors related to malignant characteristics. Its diagnostic usefulness has been recognized in clinical studies. Internal radiotherapy (IRT) with (64)Cu-ATSM is reportedly effective in preclinical studies; however, for clinical applications, improvements to r...

High thiophillicicity of the Au-nanoparticle (Au NP) surface leads to covalent attachment of D-penicillamine molecules to Au NPs to form biocompatible D-penicillamine conjugated Au NPs. The latter are highly water-dispersible, exhibit no cytotoxicity, and can readily penetrate the cell membrane to target intracellular free copper ions for selective copper detoxification in the presence of the o...

Red cell aplasia developed in a case of Wilson's disease following an increase in D-penicillamine dosage after 14 years' treatment. In vitro study of the effect of D-penicillamine on 59Fe incorporation by marrow cells did not suggest that the patient's erythropoiesis was particularly sensitive to D-penicillamine or determine the mechanism of drug toxicity. However, three weeks after the drug wa...

Forty-six patients with rheumatoid arthritis, 22 receiving D-penicillamine and 2j alclofenac, took part in a 6-month single-bind external observer trial to compare the efficacy and toxicity of these drugs in the treatment of severe rheumatoid arthritis. Both drugs were active and similar in their efficacy at 6 months as judged by clinical and laboratory measurements. Penicillamine was active th...

Clinoptilolite is used as an adsorbent to remove heavy metal cations due its function a molecular sieve. This sieve characteristic has made it possible study the efficiency of clinoptilolite and D-Penicillamine in comparative way terms adsorption metals (especially copper) from biological medium. For this purpose, was subjected grinding produce homogenized micronized powder two sizes with d90=7...

Preliminary observations on the effect of D(-)penicillamine on chronic antigen-induced experimental arthritis in rabbits are reported. Daily oral administration of penicillamine, at a dose equivalent to that usually administered to rheumatoid arthritis patients, diminished the arthritis in 2 out of 3 animals as assessed by both measurement of joint circumference and histological examination.

A case of severe diffuse systemic sclerosis with cardiomegaly and cardiac failure is described. Treatment with D-penicillamine caused a pronounced decrease in heart size, together with clinical improvement. The use of penicillamine in scleroderma heart has not previously been reported.

Two patients with rheumatoid arthritis developed evidence of hepatotoxicity while receiving D-penicillamine. Both recovered after withdrawal of the drug. These cases and a review of the literature suggested that hepatotoxicity, though rare, should be added to the list of adverse reactions to D-penicillamine.
