Multiple medical problems following agent orange exposure.

A patient exposed to agent orange and a gunshot wound during the Vietnam War has developed multiple medical problems including nocardiosis, onychomycosis (Trichophyton rubrum), multiple thromboembolic episodes, hemochromatosis, diabetes mellitus type 2, diabetic neuropathy, activated protein C resistance (without Leyden V 1st mutation), degree A-V block, lung cancer (metastatic adenocarcinoma), carpal tunnel syndrome and arthritis.

New approaches to the treatment of AIDS with special reference to overcoming interferon resistance.

This is a brief review on studies of attacking HIV through a new angle. In previous studies, we have found that many patients with AIDS are resistant to interferon (IFN) therapy, and some develop resistance during therapy. Four factors were found to be responsible for the resistance of untreated patients: (a).

Effect of increasing thiolation of the polycytidylic acid strand of poly I:poly C on the alpha, beta and gamma interferon-inducing properties, antiviral and antiproliferative activities.

Double-stranded RNAs induce interferons and cause the development of antiviral and antiproliferative activities. Antiviral activity is related to the production of interferons and other proteins that stimulate various immunologic activities, which appear to contribute to their overall antiproliferative activity. The most active double-stranded RNA, polyI:polyC, was shown to be too toxic for therapeutic use.

Resistance to interferons.

Extract: Interferons alpha, beta and gamma are a group of structurally and functionally related proteins, produced in response to viruses or double-stranded RNA and defined by their ability to establish an antiviral state in cells. They were originally discovered by Isaacs and Lindenmann (1957). Since their original discovery, several interferon genes and proteins have been identified.

Interferons and interferon inhibitory activity in disease and therapy.

Interferon (IFN) resistance is an important factor in the pathophysiology of neoplastic disorders, certain viral infections (e.g., AIDS), and autoimmune diseases (e.

Free interferon-alpha/beta receptors in the circulation of patients with adenocarcinoma.

Background: Many viral and neoplastic diseases are resistant to interferon-alpha/beta (IFN-alpha/beta) therapy or develop resistance during the course of IFN treatment. In patients with viral diseases, the authors identified four IFN inhibitors, of which the most important, most likely is a free IFN receptor of type 1 appearing in the circulation that captures and neutralizes IFN-alpha/beta.

Methods: Ninety-one cancer patients and 25 healthy individuals were studied.

[Ultra-high dosage lysis of deep venous thrombosis in ipsipedal administration along with compression].

The ipsipedal application of UHSK leads to a decisive increase of recanalisation. The fibrinolyticum will be brought in a greater quantity to the thrombotic region. The adjuvant supramalleolar compression and the increase of volume seems to be beneficial.

Improved large scale purification procedure of natural human fibroblast interferon.

Human fibroblast interferon, produced in tissue culture by a superinduction procedure, was purified 10,000-fold by chromatography to ca 50% purity as judged by SDS-PAGE. The specific activity of the interferon preparation is 2 X 10(8) and the yield is 70%. The interferon preparation is suitable for clinical use.
