Die tierische Zelle in Zellkultur
Die ersten erfolgreichen Versuche zur Züchtung tierischer Zellen außerhalb des Organismus reichen zurück in den Beginn unseres Jahrhunderts. 1907 gelang HARRI SON durch Explantation von Gewebsstücken aus Froschembryonen der Nachweis, daß in der Embryonalentwicklung die Neuriten als Fortsätze der Nervenzelle ohne Be teiligung anderer Zellen gebildet werden, und daß damit eine spezifische celluläre Funktion auch außerhalb des Gesamtorganismus zu beobachten ist [310,311].
Port-Site and Wound Recurrences in Cancer Surgery: Incidence - Pathogenesis - Prevention
Prior to now nine years, experiences of 'port-site' deposits following laparoscopic surgical procedure for malignancy, in particular laparoscopic resection of colonic melanoma, have forged a shadow at the knowledge of the laparoscopic technique within the surgical guy agement in sufferers with melanoma. these studies of port-site deposits, a few ninety instances pronounced within the literature as much as 1999, have opened a 'can of worms' and highlighted the shortage of our wisdom on melanoma telephone migration from good tu mors and the criteria that underlie their profitable implantation in surgical wounds either within the presence and shortage of a good strain pneumoperito neum.

Benefits in elderly women In many older women, the presence of concurrent illness complicates the identification of optimal local and systemic treatments. 9 The reduction in rates of recurrence is substantial, and these women tolerate the drug well. In elderly women, tamoxifen may not be an adequate substitute for definitive surgical treatment, since trials comparing tamoxifen alone as primary therapy versus tamoxifen plus surgery demon- strate a higher local failure rate with tamoxifen alone. 24,25 However, many of these trials included women who were ERnegative or whose ER status was unknown, and in some cases tamoxifen was only given for 1–2 years.
