Cryosurgical treatment of epitheliomas using the cone-spray technique.
By use of cone-shaped devices to confine liquid nitrogen spray to a restricted area on the skin surface, it is practical to treat selected epitheliomas without the aid of thermocouples. "Depth dose" is estimated by measuring the lateral spread of freezing on the surface beyond the restricted area, timing the duration of freeze, and from this information calculating the depth of freeze and the relationship of various isotherms (such as the --25 degrees C isotherm) with the frozen mass.

Blood and tissue fluid levels of a new non-steroidal anti-inflammatory preparation of nabumetone.
The pharmacokinetic properties of a new non-steroidal anti-inflammatory preparation of nabumetone have been studied in both plasma and extravascular fluids. The skin suction blister technique was used on six healthy volunteers on two separate occasions and gave good, reproducible results. A single oral dose of 1 g nabumetone achieved significant blood and skin suction blister fluid concentrations. The partition index (area under the concentration curve for the skin suction blister/area under the concentration curve for blood) showed that the orally administered drug was well diffused within the body.

Nevirapine or efavirenz combined with two nucleoside reverse transcriptase inhibitors compared to HAART: a meta-analysis of randomized clinical trials.
PURPOSE: A meta-analysis of randomized controlled trials (RCTs) was performed to evaluate effectiveness and tolerability of triple antiretroviral therapy regimens in HIV-infected patients. METHOD: RCTs including the nonnucleoside reverse transcriptase inhibitors (NNRTIs) nevirapine (NVP) or efavirenz (EFV) compared to two nucleoside reverse transcriptase inhibitor (NRTI) regimens and to three-drug regimens based on two NRTIs and one protease inhibitor (PI; highly active antiretroviral therapy [HAART]) were analyzed by Peto's method. RESULTS: A significant virological response was observed in patients treated with NNRTIs (odds ratio [OR] 3.6; 95% CI, 2.2-6.0), particularly in naïve patients (OR 7.4; 95% CI, 4.1-13.5). A fair reduction of HIV disease progression was also observed in patients treated with NNRTIs (OR 0.8; 95% CI, 0.6-1.0). Moreover, a significantly lower rate of HIV progression was observed in patients with a CD4 + lymphocyte count below 100/mm(3). Five RCTs comparing two NRTIs and one NNRTI to HAART were subsequently evaluated. A slightly higher rate of virological response was observed with NNRTIs (OR 1.6; 95% CI, 1.1-2.1), whereas no difference was observed concerning progression of HIV disease. CONCLUSION: Antiretroviral therapy including NVP or EFV was more effective in reducing viral load than therapy with only two NRTIs and was slightly more effective than HAART. Effectiveness in delaying HIV disease progression was less evident, even though lower rate of progression was observed in patients with advanced HIV infection compared to two NRTIs alone.

Serum levels of interleukin-18 in patients with uncomplicated Plasmodium falciparum malaria.
Interleukin (IL)-18, a newly discovered cytokine produced primarily by macrophages, has been shown to induce gamma interferon (IFN-gamma) production by natural killer cells, to induce the T helper type 1 response. To further elucidate the role of this cytokine in uncomplicated malaria caused by Plasmodium falciparum, serum levels of IL-18, and gamma interferon (IFN-gamma), determined by an immunoenzymatic assay, were analyzed in 40 adult patients, and in 15 healthy control subjects. A significant increase in serum levels of IL-18 was observed in patients with uncomplicated P. falciparum malaria on admission, whereas serum levels of IFN-gamma tended to increase although not significantly. Serum levels of IL-18 decreased three days later, but still remained significantly high, whereas IFN-gamma levels returned to normal levels compared to the controls. No significant correlation was found between parasitemia and serum levels of IL-18 and IFN-gamma. The increase of IL-18 levels during acute and recovery phases of uncomplicated P. falciparum malaria may reflect a proinflammatory role of IL-18 in these patients. An early and effective immune response regulated by proinflammatory Th1 cytokines, including tumor necrosis factor (TNF), interleukin (IL)-12, and possibly IFN-gamma may limit the progression from uncomplicated malaria to severe and life-threatening complications.

Effects of interleukin-8 on suppression of human lymphocyte polarization and migration by anti-LFA-1 antibody.
We investigated the role of lymphocyte function-associated antigen 1 (LFA-1) in human T cell polarization and migration assay by using monoclonal antibody specific to beta chain (CD18) and alpha chain (CD11a). T cell polarization in response to fetal calf serum (FCS) and colchicine was suppressed by the addition of CD18 and CD11a antibodies. Furthermore, T cell migration in response to lymphocyte chemotactic factor (LCF) and casein was markedly depressed by the addition of CD18 and CD11a antibodies. Additional studies to evaluate effects of interleukin 8 (IL-8) on polarization and migration of T cells preincubated with CD18 or CD11a antibody showed that IL-8 restored the capability of migration of T cells, whereas did not restore polarization activity of such cells. These studies indicate that LFA-1 plays a role in the polarization and migration of T cells and that IL-8 may positively interfer with LFA-1-adhesion molecules.

[Effects of hypoxia on the production of angiotensin converting enzyme in decompensated liver cirrhosis].
The high angiotensin-converting activity, in 13 of the 17 patients afflicted with hepatic cirrhosis, has been put in relation to the hypoxia influence. The insufficient cession of O2 seems to stimulate the enzyme activity, especially for the patients who simultaneously present low values of blood pseudo-cholinesterase. The AA think that this behaviour is to be ascribed to a deficiency of the hepatic proteic synthesis of vasoactive substances, such as the angiotensins.
