Regional thrombolysis in lower limb ischemia: new pharmacological and non-pharmacological aspects.

Regional thrombolytic therapy for arterial occlusion of the limbs uses several catheter-guided techniques and various infusion methods and therapeutic schemes. There is no definite proof of superiority of any agent in terms of efficacy and safety. A meta-analysis of randomized trials comparing surgery to thrombolysis in leg ischemia shows no significant difference in major amputation and mortality between these two management options. Major bleeding is the main complication. Recent developments include the introduction of new thrombolytic agents, associated infusion of glycoprotein IIb-IIIa blockers and use of ultrasound to disrupt thrombi or facilitate thrombolysis.

The chemistry, pharmacology and clinical pharmacology of diflunisal.

Studies are reviewed on diflunisal, a new analgesic agent with an improved therapeutic index, compared with acetylsalicylic acid, in animals and humans. Pharmacokinetic data indicate that a twice-daily dosage regimen of diflunisal is adequate for therapeutic purposes. Diflunisal inhibits prostaglandin E synthesis, but in humans at clinically effective doses it does not alter bleeding time or platelet aggregation. Diflunisal is uricosuric at clinically effective doses. No clinically important drug interactions with diflunisal have been found to date, although some slight alterations in blood and urine drug levels have been noted. The slight increase in prothrombin time seen when diflunisal and acenocoumarol were co-administered is not considered to be of major clinical importance.

Postexposure management and treatment of anthrax in dogs--executive councils of the American Academy of Veterinary Pharmacology and Therapeutics and the American College of Veterinary Clinical Pharmacology.

Dogs are generally at low risk of developing disease following exposure to anthrax. When disease does occur, it appears associated with oral exposure to the bacteria leading to massive swelling of the head, neck, and mediastinal regions. Death is due to toxemia and shock. For animals at high risk, such as search and rescue dogs with a known exposure, doxycycline at 5 mg/kg orally once daily for 45 to 60 days is suggested as a prophylactic treatment. Additional information on the diagnosis, prevention, and treatment of the disease in dogs is presented.

Studies on pharmacological activation of human serum immunoglobulin G by chemical modification and active subfragments. IV. Induction of anti-inflammatory activity by chemical cleavage of interchain disulfide bonds in human immunoglobulin G and pharmacological activity of alkylated subfragments.

Commercially available human serum immunoglobulin G (IgG, native IgG) was separated into two fractions (Fr.I and II) using a diethylaminoethyl cellulose column. Heavy and light chains containing fractions were obtained from these two fractions after carboxamide-methylation. Thus, these fractions were subjected to an anti-inflammatory screening procedure and were shown to have a potent inhibitory activity against rat carrageenin induced paw edema, while no effect was observed in native IgG, Fr.I or II. The reduction and alkylation of the interchain disulfide bonds were essential to induce the anti-inflammatory activity. The anti-inflammatory activity of alkylated heavy and light chains of Fr.I (Fr.I-H and I-L) was also noted in subacute inflammation caused by the felt pellet and croton oil granuloma methods. Moreover, strong membrane stabilizing activities of Fr.I-H and I-L were demonstrated in vitro using rat red blood cell membrane and liver lysosomal membrane.
