To begin to understand the potential role of SPARC in lung injury, we studied the development of pulmonary fibrosis induced by bleomycin in mice deficient in SPARC. It was observed that bleomycin administered intratracheally induced a more exuberant inflammatory and fibrotic response in the lungs of SPARCdeficient than in wild-type control mice. In contrast, the pattern and severity of pulmonary fibrosis as well as the degree of leukocyte accumulation were similar in wild-type and mutant mice after intraperitoneal bleomycin treatment. Furthermore, increased neutrophil accumulation was observed in SPARC-deficient mice after acute chemical peritonitis. Together, these findings not only provide evidence of a role for SPARC in the host response to pulmonary insults that is likely to be complex and context specific, but they also implicate SPARC in modifying the recruitment of neutrophils into sites of acute inflammation. SPARC, an 40-kDa protein secreted by a number of cell types including macrophages and fibroblasts, is found in the matrix of tissues responding to or recovering from injury 18 ; . Its importance in these processes is suggested by a variety of in vitro studies that have shown that SPARC disrupts cell adhesion, modifies the extracellular matrix, inhibits the cell cycle, and antagonizes the effects of growth factors 5, 8 ; . Although its specific role in the host response to lung injury is not known, the recent observation by Strandjord et al. 23 ; that intratracheal bleomycin-induced lung injury in mice resulted in an 3-fold increase in SPARC mRNA suggests that SPARC may participate in these processes. However, understanding the physiological role s ; of SPARC has proved difficult because of a lack of readily available reagents capable of antagonizing the function of SPARC in vivo. Thus the generation of mice deficient in SPARC provides an important vehicle for studying the function of this protein in vivo. Pulmonary injury induced by bleomycin delivered intratracheally or intraperitoneally provides two wellestablished models of lung fibrosis 4, 24 ; . With these systems, we observed that the fibrosis that results from the intratracheal instillation of bleomycin assessed histologically and by collagen content ; was greater in mice deficient in SPARC compared with that in wildtype animals, whereas the absence of SPARC did not alter the pattern and severity of fibrosis that developed after the intraperitoneal administration of bleomycin. These findings suggest that the role of SPARC in lung injury is dependent on the type, intensity, and duration of insult. To evaluate this proposal further, pulmonary fibrosis in other models of lung injury, e.g., silica-induced injury 15 ; , need to be the subject of future investigations. Our findings of increased injury and fibrosis in SPARC-null mice after intratracheal bleomycin treatment differ from those of Strandjord et al. 23 ; , who reported that intratracheal instillation of bleomycin in these mutant mice resulted in less fibrosis as assessed.

Some patients improve upon discontinuing therapy with a hormone that has lost its effectiveness. ~Ihis withdrawal remission should he fully utilized before changing to another form of treatment. Something is always kept in reserve for that time when the disease will he refractory to the currently employed therapy. Only minor differences exist in application of the several therapeutic modalities to the pre- and post-meno pausal patient. In the premenopausal pa tient, irradiation is the best form of ther apy whether the lesion is in bone, skin, soft tissue, liver or brain. In case of pro gression of disease"development of new or advance of old lesions"while radiation is being used, castration, preferably sur gical, is the next therapeutic step. Irradia tion castration, often incomplete, should be reserved for patients who refuse or can not tolerate surgical procedure. Castra tion should not he used as a prophylactic measure hut reserved until symptoms ap pear. If the disease continues to progress after irradiation and castration, andro genie or estrogenic therapy is begun. Tes tosterone and ethinyl estradiol are the recommended products. About 20 per cent of patients are benefited objectively by androgen therapy, and many more are improved subjectively. Estrogens are used especially in older patients with soft tissue lesions. When hormone therapy becomes ineffective, adrenalectomy or hy pophvsec tomy is indicated. The latter procedure is recently being preferred in spite of the hazard of complicating diabetes insipidus. And finally cortisone, after all else fails, may carry a semiterminal patient in com parative comfort for a considerable period and boniva. Bleomycin scuba 8: 52AM AN.00005 High resolution simulations of the single-wavelength Richtmyer-Meshkov flow1 , PRAVEEN RAMAPRABHU, CNLS, Los Alamos National Laboratory, GUY DIMONTE, Los Alamos National Laboratory -- The single-mode RichtmyerMeshkov RM ; instability was investigated in three dimensions, using the compressible FLASH code, with Adaptive Mesh Refinement with effective resolution of up to 256 zones , where is the wavelength of perturbation. The massively parallel capability of this code permitted investigation of this flow in computationally difficult regimes: Mach numbers up to 15, small initial amplitudes to ensure linearity of perturbations, and fluids with starkly different compressibilities. Linear and nonlinear theories of RM were evaluated under these conditions, and our findings will be presented. Other effects such as dimensionality, and Atwood number dependence were also studied.

Possible heat treatment and interference of blood flow, the results of Marmor et a!. 12 ; can be interpreted in several ways: a ; the effective bleomycin concentrations have accumulated before the microvascular damage occurs; b ; during the heating and short initial 43# C period, hyperthenmia actually increases the blood flow; or c ; 30 minutes at 43# C not sufficient is to damage the microvascular structure in KHT tumors. Our 57Co-bleomycin scanning data summarized in TABLE I strongly suggest that despite the fact that the microvascular structure of the heated tumor may have been damaged, the rate of accumulation of 57Cobleomycin is insignificantly changed from that of unheated tumors.

The remaining lifespan of patients with symptomatic malignant pleural effusions is very limited. The goal of treatment should be rapid and durable relief of symptoms. In all but the most seriously ill patients, palliative pleurodesis is the management of choice. The ideal procedure should be simple, safe, well tolerated, of lifelong success, and cost effective in combining a low initial expense and minimal recurrence rate. The present study is to our knowledge the first to directly compare thoracoscopic talc poudrage under local anesthesia with bleomycin instillation via a small-bore chest tube for pleurodesis. It demonstrates the superior efficacy and cost effectiveness of thoracoscopic talc pleurodesis. Our study was a comparison of two standard procedures used in many European hospitals. It has to be taken into consideration that different substances and methods of application were used in our two study groups. Bleomycin pleurodesis is esteemed by many clinicians for its simplicity and rapid availability. In our study, bleomycin pleurodesis was safe and well tolerated. Although its short-term success rate was acceptable 59% ; , its long-term efficacy was disappointing, with almost half of the patients treated with it requiring repeated treatments within half a year. In contrast, we observed only two early failures of thoracoscopic talc pleurodesis under local anesthesia, both within the first month after therapy. One of.
