BRAIN ANGIOGENESIS IN DYSTROPHIC MDX MICE IS MEDIATED BY AN INCREASED PROTEOLYTIC ACTIVITY AND VEGF EXPRESSION Beatrice Nico, Domenica Mangieri, Patrizia Corsi, Roberto Ria, Angelo Vacca, Domenico Ribatti, Luisa Roncali Department of Human Anatomy and Histology, Department of Physiology and Pharmacology, Department of Biomedical Sciences and Human Oncology, University of Bari Medical School Dottorato di Ricerca in Scienze e Tecnologie Cellulari-XIX ciclo Sede: Universit degli Studi di Bari e-mail: d.mangieri histology ba In the Duchenne muscular dystrophy DMD ; and in the mdx mice, an experimental model of DMD, brain alterations involving the microvasculature with an increment in vascular density and permeability, opening of the tight junctions and damages of the perivascular glial cells have been reported Nico et al., 2002, 2003 ; . An enhanced expression of the vascular endothelial growth factor VEGF ; and of its receptor-2 VEGFR-2 ; has been reported in the mdx brain, suggesting a role of VEGF in mdx brain angiogenesis. In order to estabilish a correlation between the extent of the angiogenesis and proteolytic activity, we investigated in the brain of 20 month old mdx mice and in the controls: 1 ; the expression of VEGF and matrix metalloproteinase-2 and 9 MMP-2; MMP-9 ; by immunohistochemistry and western blot; 2 ; the expression of MMP-2 and MMP-9 mRNA by in situ ibridation and RT-PCR and their activity by zimography; 3 ; the vessels ultrastructure and permeability by electron microscopy and by horseradish peroxidase HRP ; intracardiac injenction. Results showed that in the mdx mouse, compared to the control one, an higher expression of MMP2 and MMP-9 content was detected by western blot in the brain and in the choroidal plexuses. In situ hibridation revealed MMP-2 and MMP-9 mRNA in the epithelial cells of choroidal plexuses and in the endothelial cells. Gelatin zymography demonstrated an increased acivity of both MMP-2 and MMP-9 in mdx brain respect to control. Immunohistochemistry showed a strong labelling of the mdx vessels and choroidal epithelial cells with both anti-MMP-2 and anti-MMP-9 antibodies. Higher expression of VEGF was detected by western blot in the mdx brain. Ultrastructurally, the vessels appeared lined by irregular endothelial cells, with numerous vesicles and vacuoles and opened TJs, and were enveloped by swollen and discontinuous glial endfeet. Finally, the vessels were higly permeable to HRP, as demonstrated by numerous areas of perivascular escape of the marker. These results suggest that in the mdx brain the absence of dystrophin induces an increment of VEGF expression and MMP-2 and MMP-9 proteolytic activity, wich in turn might be responsible of an increment of the brain angiogenesis and vascular permeability. 1 ; Nico B. et al.

Think big pharmaceutical companies still face a big problem in terms of growth of pipelines relative to the rate of patent expirations, which are still going to be enormous over the next several years. PAUL GINSBURG, PH.D.: ready for questions. Thank you. We're just about. It also appears that a sulfhydryl-binding agent can not only induce bleb formation but can in some way further alter the properties of the plasma membrane. This is illustrated by N-ethylmaleimide, which at first produced typical scallop blebs; but these rapidly increased in size to become elongated, distorted, sausage-like structures ~xith considerable plasticity Fig. 6 ; . These may detach fl'om the cell and float through the medium, assuming bizarre shapes while rapidly expanding and collapsing. In addition to those of sarcoma 37, the cells of 6 additional mouse ascites tumors, 2 rat ascites tumors, plus 4 h u malignant, 2 mouse malig n a n and 3 normal cell lines grown i * ~ vitro also yielded blebs of all three types when exposed to active bleb-forming agents. These cells and their bleb responses arc listed in Tables V and VI. Inspection of these tables discloses some dill'er ences in certain cases with regard to the type of bleb induced by a specific blebbing agent on a specific : ell. The cells of Yoshida sarcoma, HcLa, D189, D164, and D227 produced acentric rather than symmetrical blebs in response to Protargol; P288 and leukemia L1210 tended to give rise to symmetrical and acentric blebs rather than acentrie blebs alone when exposed to Ncohydrin; and symmetrical plus acentric blebs rather than scallop blebs to both p-arsenosobenzoic acid and N-ethyl-maleimide. P288 yielded symmetrical rather than scallop blebs to both p arsenosobenzoic acid and N-ethyl-maleimide. ~l'hc significance of these differences in behavior is not apparent. The induction of these cell blebs is i n the tonicitv of the m e d which they are contained, i.e., bleb lormation is not due to changes in osmotic pressure per se.

Taking tsmsulosin under fasted conditions results in a 30% increase in bioavailability auc ; and 40 to 70% increase in peak concentration c max ; compared to fed conditions and flunarizine and tamsulosin.
Tamsulosin, at oral doses causing maternal toxicity, was not embryotoxic or teratogenic when administered during gestation in rats doses up to 300 mg kg day ; or rabbits doses up to 50 mg kg day.

Residual volume and 1 acute retention, that might be explained by the high amount of toxin used for this indication, have been also noted. As opposed, Radzieszweski and Borkowski observed marked improvement of bladder overactivity in 12 patients at 1 month follow up without change in the residual volume by using 300 Dysport units [60]. In another prospective study, BoNT was tested on 16 patients suffering from incontinence with motor 9 patients ; or sensory urge 7 patients ; with or without a neurological impairments. After treatment with 200 Botox units into the detrusor muscle, 13 patients were dry and 3 patients with sensory incontinence remained incontinent. Nine of the treated patients were free of urge symptoms. Seven patients 1 with motor and 6 with sensory urge ; noted no clinical improvement. URINARY RETENTION Recent reports clearly demonstrated that BoNT might be effective in reducing urethral resistance and facilitate voiding efficiency in patients who had either cauda equina lesion or peripheral neuropathy, as well as in those with detrusor failure and poor relaxing urethral sphincter. The role of BoNT injections into the external urethral sphincter for a variety of bladder outlet obstructions and to decrease outlet resistance in patients with acontractile detrusor wishing to void by Valsalva manoeuvre has been studied by Phelan et al. [61]. After injection of 100 Botox units, 20 patients were able to void without catheterization. Kuo et al. [62] repeated the experience in 20 patients with dysuria or urinary retention due to detrusor underactivity and non-relaxing urethral sphincter, who were refractory to conservative treatment. After treatment, spontaneous voiding resumed in 11 patients and significantly improved in 5. As opposed to Kuo and Phelan reports, Fowler et al. [43] found no significant improvement of micturition in 6 women who had difficulties in voiding or complete urinary retention due to abnormal myotonic-like activity in the striated urethral sphincter and who were treated with transperineal BoNT injection. However, the actual controversial results strongly suggest that further studies are necessary to clarify the exact therapeutic role of BoNT injections in these cases. PROSTATIC INDICATIONS Chronic Prostatic Pain Chronic prostatic pain is a common situation confronting the practising urologist. Up to now, the different therapies of this syndrome and their longstanding results are mostly frustrating. Recently, 4 consecutive men with chronic nonbacterial prostatitis and poor bladder emptying because of spastic external urethral sphincter mean duration of symptoms 18 3 months ; , who failed to respond to tamsuloxin 0.4 mg once daily for more than 4 months were treated with 30 Botox units. All the patients had uroflowmetric studies to assess times of urinary flow TQ ; and maximum urinary flow TQmax ; , maximum flow Qmax ; , average flow Qave ; , and total urinary volume Vcomp ; . An increased value of TQ and TQmax with a normal value of Qmax was taken to be indicative of incomplete relaxation of bladder neck. Within 1 week of and flupenthixol.
