02/01/2013 - "For staging, because orcein staining was not available in this study, 2 criteria (fibrosis and bile duct loss) were independently scored from 0 to 3 on the basis of their degrees, and a final stage score was created from the sum. "
10/01/1980 - "Such a study showed orcein-positive liver cells in 7 out of 33 (21.2%) cases of HCC associated with cirrhosis. "
01/01/2015 - "MT, SR, and orcein staining showed concordant results in 89.6% of cases in staging CHC, without significant difference in both semiquantitative and quantitative evaluations of fibrosis. "
01/01/2015 - "Orcein is the only staining able to evidence the absence of true elastic fibrosis, which is a typical feature of AH. "
06/01/2013 - "Development of cirrhosis-related conditions correlated well with the new staging system compared with the 2 classical staging systems, and in particular, the amount of deposition of orcein-positive granules could reflect development of cirrhosis-related conditions (scores 0-1 versus scores 2-3 groups, P < .0001). "

09/01/1991 - "Results of orcein staining and findings obtained with non-contrast-medium-enhanced computed tomography (CT) and magnetic resonance (MR) imaging (T1- and T2-weighted images) were compared for 53 histologically confirmed hepatocellular carcinomas (HCCs). "
08/01/1989 - "Orcein-positive granules in liver cell carcinoma."
06/29/1979 - "Of the 63 cases of seronegative hepatoma, 3 showed some round orcein-positive inclusion bodies in the cytoplasm of the neoplastic and the non-neoplastic cells; these bodies were not stained by the two immunological methods."
09/01/1978 - "Massive pattern distribution of orcein-positive liver cells was statistically significant in cirrhotic livers with or without hepatoma, but morphological characteristics of orcein-positive liver cells could not be correlated in significance with dysplasia and hepatoma. "
01/01/1977 - "There is a significant difference in the frequency of hepatocellular carcinoma in orcein-positive and orcein-negative cirrhotic livers (28 out of 50, 10 out of 40 respectively). "

07/01/1985 - "Orcein-positive granules were never found in patients with acute liver disease. "
01/01/1983 - "Orcein-positive granules were never found in acute liver disease. "
01/01/1976 - "The occurrence of orcein-positive hepatocellular material in various liver diseases."
09/15/1987 - "Orcein-positive hepatocellular material (OPHM), found in 18 of 44 hepatocellular carcinomas (HCC), was compared histochemically and ultrastructurally with similar granular materials in other liver diseases. "
01/01/1979 - "Histochemical study of orcein-positive hepatocellular material in paraffin sections of liver biopsy samples in the course of various liver diseases."

10/01/1985 - "Orcein-positive material in Kupffer cells appears to consist mainly of lipofuscins developing in the course of acute hepatitis."
10/01/1985 - "Fifty-five (57%) out of 96 cases with orcein-positive Kupffer cells had acute hepatitis, and 46 (84%) of these 55 were in the late stage of their illness. "
07/01/1976 - "In contrast, among the 38 chronic carriers, 25 showed positive cytoplasmic staining with anti-HBs and/or orcein, while one of them (with chronic aggressive hepatitis) also showed nuclear staining with anti-HBc. "
01/01/2015 - "To compare Masson's trichrome (MT), Sirius red (SR) and orcein staining in acute hepatitis (AH) and to correlate them with transient elastography (TE), a noninvasive method to assess hepatic fibrosis. "
10/01/2013 - "They were increased in PBC patients with high degrees of cholangitis activity, a mild degree of hepatitis activity, fibrosis, orcein-positive granules, and early stages. "

07/01/1988 - "In the stroma of colonic carcinomas, vitronectin was often situated in areas in which elastic fibers were visualized by orcein counterstaining. "
04/01/1981 - "Orcein-positive hepatitis B surface antigen and liver carcinoma: their association in an Eastern US population."
01/01/1983 - "[The relation of hepatitis B virus to chronic hepatitis, cirrhosis and primary hepatocellar carcinoma--a study of 367 cases of liver biopsy with orcein staining]."
01/01/1983 - "1063 hepatic cirrhoses, 138 epicirrhotic carcinomas, and 138 carcinomas without cirrhosis from the autopsy material of the Dresden region obtained from 1970 to 1979 were examined for the occurrence of HBsAg by means of reclassification and after-staining of the documented section material with orcein staining according to Shikata. "
01/01/1982 - "The amount and distribution of PAS-, Alcian blue-, or orcein-positive substances on the cell surface and/or in the interstitial elements of the carcinomas differed from that of choroid papillomas examined in our laboratory. "
