H-Ras Oncogene Expression and Angiogenesis in Experimental Liver Cirrhosis

Table 1

Distribution of mean, standard deviation (SD), median, and ranges of vascular density (VD) and H-ras expression in normal livers (group I), nonfibrotic (group II), fibrotic (group III), and cirrhotic livers (group IV). The Mann-Whitney 𝑈 test was used.

I (𝑛=6)	3.1 ± 0.95	3	0–7	>0.05	0.66 ± 0.58	0	0–4	>0.05
II (𝑛=8)	6.82 ± 2.5	7	2–11	<0.05	13 ± 6.08	12	3–30	<0.05
III (𝑛=8)	11.3 ± 2.4	10	9–16	<0.05	19.6 ± 6.39	22	10–30	<0.05
