Inhibition of HBsAg secretion from Alexander cell line by Phyllanthus amarus.

Alexander cell line, an human hepatocellular carcinoma derived cell line which has the property of secreting HBsAg in the supernatant was used to study the antiviral property of phyllanthus amarus. Aquous extract of Phyllanthus amarus was evaluated for its in vitro ability to inhibit HBsAg secretion on a dose dependent manner. It was seen that P. amarus at 1mg/ml concentration on a single dose inhibited the secretion of HBsAg for a period of 48 hours. This experiment proved the anti hepatitis B virus property of P. amarus at cellular level and further confirmed its beneficial use in the treatment of acute and chronic hepatitis B and healthy carriers of HBV.

Non-organ specific & organ-specific auto-antibodies in hepatitis-B virus associated glomerulonephropathies.

Eighty eight patients of glomerulonephropathies (HBsAg positive 67; HBsAg negative 21) and 88 matched and healthy controls were screened for non-organ specific autoantibodies-ANA, AMA, ASMA and APCA by indirect immunofluorescent technique. The 2.3 per cent positivity in the test group and the 8 per cent positivity in the control group did not suggest the involvement of hepatitis-B virus (HBV), as an influencing or associated agent. When 48 patients with glomerulonephropathies and 23 controls were screened for liver cell membrane (LMA) and renal cell membrane antibodies (RMA) by indirect immunofluorescent technique using isolated rat hepatocytes and renal cells, 79.2 per cent LMA positivity was seen in the HBsAg positive group and 41.7 per cent in the negative group and RMA positivity was 58 per cent in the positive group and 25 per cent in the negative group. Simultaneous positivity for both LMA and RMA was recorded in 50 per cent of the HBsAg positive patients and 15.7 per cent of the negative ones. The results suggest the possibility of an organ specific autoimmune trigger more frequently in HBV associated glomerulonephropathy.
