A number of recent research studies have been done on different species of the plants of the genus Phyllanthus. The plants are widely distributed in most tropical and subtropical countries and have long been used for the treatment of liver diseases in China and India. / Hepatitis B virus (HBV) is a major pathogen of human viral hepatitis. It has been estimated that 350 million people are chronic carriers of HBV throughout the world. Increasing evidence indicates that persistent viral infection of the liver is associated with cirrhosis and hepatocellular carcinoma. Hepatitis B virus belongs to a family of DNA viruses called hepadnaviruses. The current treatments of HBV infection with interferon or lamivudine have several disadvantages, and there appears to be much room for improvement in terms of medical treatment. / My project research focuses on two poorly characterized Indian Phyllanthus species called Phyllanthus nanus ("PN") and Phyllanthus niruri ("PI"). In my studies, random amplified polymorphic DNA ("RAPD") technique and high performance liquid chromatography ("HPLC") fingerprinting were used to authenticate different species of Phyllanthus. Both aqueous and ethanolic extracts of PN and PI were prepared to study their cytotoxicity in hepatoma cell lines. The effect of these extracts on hepatitis B virus was also examined in the HBV-genome integrated cell lines - PLC/PRF/5 (Alexander) and HepG2 2.2.15. Microparticle enzyme immunoassay ("MEIA") and enzyme-linked immunosorbent assay were used to measure the amount of hepatitis B surface antigen ("HBsAg") and hepatitis B e antigen ("HBeAg") secretion from the cell lines. RT-PCR was used to detect the change in HBsAg mRNA's expression level in the drug-treated cell lines. Real-time PCR was also employed to examine the effect of drug treatment on the level of HBV DNA replication and the amount of virions secreted into the medium. The experimental results showed that both the aqueous and ethanolic extracts of PN and PI exerted suppressive effect on HBsAg secretion and HBsAg mRNA level. The PN and PI ethanolic extracts also showed mild suppression of viral replication in vitro. The ethanolic extract of PN seemed to be more potent in suppressing HBV than the other extracts tested.

Immortalized normal hepatocytes AML-12 or primary hepatocytes were cultured in control, and the methionine and choline deficient (MCD) culture medium in the presence or absence of Phyllanthus urinaria for 24 hours. Hepatocyte triglyceride contents, release of alanine aminotransferase, lipoperoxides and reactive oxygen species production were determined in the cell culture study. Age-matched wild-type C57BL/6 and diabetes db/db mice were fed control or MCD diet for 10 days with or without Phyllanthus urinaria. The levels of Hepatic steatosis, necroinflammation, triglycerides and oxidative stress were investigated. Hepatic expression of inflammatory factors and lipid regulatory mediators were assayed. The results demonstrated that Phyllanthus urinaria reduced steatosis and alanine aminotransferase (ALT) levels in culture of hepatocytes in a dose-dependent manner. Phyllanthus urinaria protected the livers against MCD-induced hepatic fat accumulation and steatohepatitis in mice. This effect was associated with repressed levels of hepatic lipid peroxides, reduced expression of cytochrome P450 (CYP) 2e1, pro-inflammatory tumor necrosis factor-alpha (TNF-alpha), interleukin-6 (IL-6), dampened activation of inflammatory C-jun N-teuninal kinase (JNK) and nuclear factor kappaB (NF-kappaB), increased expression of lipolytic Cyp4a10 and suppressed transcriptional activity of lipogenic CCAAT/enhancer binding protein beta (C/EBPbeta). Hepatic acyl co-enzyme A oxidase (ACO) that regulated hepatic beta-oxidation of fatty acid and other lipid regulators were not affected by Phyllanthus urinaria. / Non-alcoholic steatohepatitis (NASH) results from excessive accumulation of hepatic fat (steatosis) and oxidative stress. Therefore, inhibition of fatty acid cytotoxicity and liver inflammtary change is an important goal in the treatment of NASH. Phyllanthus urinaria, a herbal medicine, has been reported to have potential anti-oxidant property. We tested the effects of Phyllanthus urinaria on nutritional steatohepatitis both in vitro and in vivo, and determined the mechanism of its action. / Our study indicated that Phyllanthus urinaria effectively prevented MCD-induced steatohepatitis. This effect were probably mediated through dampening oxidative stress, ameliorating inflammation and decreasing lipid accumulation. Phyllanthus urinaria deserves further evaluation for its potential therapeutic effect on NASH in humans. / Shen, Bo. / Adviser: Henry Ly Chan. / Source: Dissertation Abstracts International, Volume: 70-09, Section: B, page: . / Thesis submitted in: November 2008. / Thesis (Ph.D.)--Chinese University of Hong Kong, 2009. / Includes bibliographical references (leaves 128-142). / Electronic reproduction.

Ganoderma lucidum and Cordyceps sinensis are medicinal fungi commonly used in Chinese medicine. The allied species of G. lucidum, G. sinense and G. tsugae as well as the allied species of C. sinensis, C. militaris are also commercially available as health supplements. The present study aimed at evaluating and comparing the biological activities of the different parts of fruiting bodies of Ganoderma species (whole fruiting body, pileus, stipe, spores and spore oil) and Cordyceps species (whole fruiting body, stroma and larva/pupa). / The extracts of C. sinensis and C. mililaris could stimulate secretion in human airway epithelial cell Calu-3, implying the potentials of these extracts to modulate the mucociliary clearance. The potencies of the stimulatory effects of the stroma of fruiting bodies showed stronger effects than the larva/pupa. All parts of C. sinensis and the stroma of C. mililaris could modulate the proliferation of human peripheral blood mononuclear cells and the different potencies of immunomodulatory effects were also observed. / The results demonstrated that the hot water extracts of G. lucidum, G. sinense and G. tsugae possessed antiproliferative effects on human breast cancer cell lines MCF-7 and MDA-MB-231. The extracts from the stipes showed stronger inhibitory activities on cancer cell proliferation than those from pilei. Furthermore, the extracts from the whole fruiting body and stipe of G. lucidum possessed strong antitumor effects on the nude mice bearing MCF-7 xenografts and the BALB/c mice bearing sarcoma S-180 allografts as well as strong immunomodulatory effects in terms of stimulating splenic lymphocyte proliferative responses. The oral administrations of spores and spore oil did not show significant inhibition on MCF-7 xenografts growth but they inhibited sarcoma allografts growth effectively. / The strong biological effects of the stipe of Ganoderma and the stroma of Cordyceps were showed for the first-time. This study sheds light on how the fruiting bodies of Ganoderma or Cordyceps should be used to achieve the most out of their pharmacological properties. This study also demonstrated the novel application of Cordyceps in promoting secretion in human airway submucosal glands, which reinforces the rationale of using this fungus for treating respiratory diseases. / Yue Gar Lee Grace. / "August 2006." / Advisers: Leung Ping Chung; Kwok Pui Fung; Bik San Clara Lau. / Source: Dissertation Abstracts International, Volume: 68-03, Section: B, page: 1584. / Thesis (Ph.D.)--Chinese University of Hong Kong, 2006. / Includes bibliographical references (p. 318-340). / Electronic reproduction.
