DESCRIPTION OF THE RELATED ART

Liver diseases have great impact on human health. Hepatitis is a kind of liver diseases, which is caused by liver inflammation due to infection of a variety of pathogens, which include, but are not limited to, viruses, bacteria, fungi, and protozoa. Hepatitis can be categorized as acute, chronic, or fulminant.

Viral hepatitis is an enterically transmitted liver disease due to viral infection. The major transmission means for viral hepatitis is through ingestion. Viral hepatitis can also be transmitted through blood transfusion or similar means of hepatitis-virus-carrying blood or blood product such as blood plasma. Viral hepatitis is widespread around the world. For example, there are approximately thirty million (30,000,000) viral hepatitis patients in China including an estimated number of nine million (9,000,000) new patients each year, and about one hundred million (100,000,000) hepatitis B virus (HBV) carriers. It is estimated that 10% of the pregnant women in China are HBV carriers. About one hundred thousand (100,000) people in China die of liver cancer originated as liver diseases each year. Depending on the major etiologic agent, viral hepatitis is categorized into Hepatitis A,

Hepatitis B, Hepatitis C, Hepatitis D, and Hepatitis E. Hepatitis A is caused by hepatitis A virus (HAV); Hepatitis A can affect anyone and occur in isolated cases as well as widespread epidemics. Hepatitis B is a serious disease caused by hepatitis B virus (HBV). HBV attacks the liver and can cause lifelong infection, cirrhosis (scarring) of the liver, liver cancer, liver failure, and death. Flepatitis C is caused by hepatitis C virus (HCV). Hepatitis D is caused by the hepatitis D virus (HDV) which is a defective single-stranded RNA virus that requires the helper function of HBV to replicate and to synthesize envelope protein composed of HBsAg to encapsulate HDV's genome. Hepatitis E is caused by hepatitis E virus (HBV), which is an etiologic agent of enterically transmitted non-A, non-B hepatitis. HEV is a spherical, non-enveloped, single-stranded RNA virus of approximately 32 to 34 nm in diameter. HEV has been provisionally classified in the Ccdiciviridae family; however, the organization of the HEV genome is substantially different from that of other Caliciviruses. and HEV may eventually be classified in a separate family. The most common types of viral hepatitis are Hepatitis A, Hepatitis B, Hepatitis C. and Hepatitis E, which have similar major symptoms including decreased appetite, nausea, unease upper abdomen, lack of strength, etc. Acute jaundice is also one of the common symptoms. Chronic hepatitis is very difficult to cure. Severe hepatitis often comes on quickly and results in high mortality. Traditional Chinese herbal compositions have been developed and shown success for preventing and treating various liver diseases. The types of traditional Chinese herbal medicine for treating hepatitis include medications having single or multiple herbal components and medications made of active ingredients extracted from the herbs.

For example, Qianglining injection solution is made of glycyrrhizic acid extracted from licorice {Glycyrrhiza). Glycyrrhizic acid reacts with ammonia to form a water-soluble ammonium salt of glycyrrhizic acid, which then can compound with amino acids. The injection solution is useful for treating chronic viral hepatitis, liver cirrhosis, and hepatoma. The total effective rate of qianglining injection solution is about 87.5%>. in which 64.1% is significant, according to clinical studies conducted on hepatitis patients provided by Shanghai Huashan Hospital, Shanghai, China.

Yanhuanglian injection solution is derived from ground herb Yanhuanglian grown in Guangxi Province in China. The solution is useful for treating various types of hepatitis, liver cirrhosis, and liver cancer, with a reported clinical efficacy rate of 81.47%). The solution has an effective rate of 93.88% in cases involving acute jaundice patients, 87.50% in non- jaundice type hepatitis patients, 87.09% in chronic active type hepatitis patients, 69.23% in prolonged type hepatitis patients, and 80.95% in chronic cirrhosis patients. However, only 17.91%o of the patients show changes of HBV surface antigen from positive to negative. Shandougen {Radix Sophorae Tonkinensis) injection solution is useful for both acute and chronic viral hepatitis, and especially effective for chronic active hepatitis. As studied by Guangxi Medical College in Guangxi province, China, the total effective rate is 91.79% for chronic active hepatitis patients, and the substantial effective rate is 54.23%. Also, 64.93%> of the patients' glutamate-pyruvate transaminase (GPT) level returns to normal in two (2) months after the treatment. However, some patients show recurring symptoms of hepatitis after the treatment is discontinued.

Umbellate pore fungus {Polyporus umbellata) injection solution has functions of improving immune function, inhibiting tumor, lowering level of transaminase, and inhibiting replication of hepatitis virus. After treating patients with chronic viral hepatitis with umbellate pore fungus injection solution, 35.6% of the patients return to normal serum GPT (SGPT) level, 76.61%o of the patients show some lowering effects on transaminase level, 38.6%o of the patients show HBV E antigen turning negative, and 13.1%o of the patients show surface antigen turning negative. Qidun fruit acid tablet has a total effective rate of 94.4% in patients with acute jaundice-type hepatitis. The total recovery rate is 64.8%. Qidun fruit acid tablet also shows an effective rate of 69.8% in chronic active hepatitis, in which 43.7% of the patients show a significant effect. The rate for HBsAg positive turning negative is 16.8%.

Gandezhi (Liver-curing) capsule has Wuren alcohol, scutellarin, mulberry fruit-spike (Fnictus Mori Albae), salvia root {Radix Salviae Miltiorrhizae), and licorice {Radix

Glycyrrhizae Uralensis) and is useful for lowering transaminase level. It has an effective rate of 80.0%o for treating prolonged hepatitis and chronic hepatitis, according to studies reported by Guangzhou Zhongshan Medical College Hospital in China. There has been no report which shows that Gandzhi has effect on HBV Antigen turning negative. Danggui (Chinese angelica root) pill is made of Chinese angelica root {Radix

Angelicae Sinensis) and licorice {Radix Glycyrrhizae Uralensis). In a study conducted by Beijing Medical College in China, Danggui pill is effective for treating prolonged hepatitis (with an effective rate of 84.4%), chronic hepatitis (with an effective rate of 79.1%o), and cirrhosis resulted from hepatitis (with an effective rate of 73.6%). Hugang (liver-protecting) tablet is made from schisandra_/rz./7 (Fritctits Sc/iisaiidrcie

Chinensis) alcohol extractant, liver-protecting extractant (including Junchen. Zilui. and woad root (isatis root, Radix Isatidis sen Baphicacanthi)), and biliary powder, etc. It has an effective rate of 95.08%o for treating chronic hepatitis (70%o with significant effect), and 82.5%o for treating cirrhosis (63% with significant effect).

Jigu ("chicken bone") grass pill is made of Jigu grass, billiary powder, and bovine bezoar {Calculus Bovis). As studied by Beijing Children's Hospital in China, Jigu grass pill has a total effective rate of 100%o in patients with acute viral hepatitis, 73.3% in patients with chronic active hepatitis, 70.4% in patients with chronic prolonged type hepatitis. However, Jigu grass pill does not appear to have any effect on other types of prolonged hepatitis. Wuzi ("five ester") capsule is made from schisandra/rz. / (Fructus Schisandrae Chinensis) alcohol extractant. It shows function of lowering GPT level and is useful for treating chronic prolonged hepatitis. The total effective rate of wuzi capsule is 95.33%), in which 74.21% is significant.

DETAILED DESCRIPTION OF THE INVENTION Traditional Chinese medicine has been in existence for more than two thousand years. It has a proven record of success for curing many kinds of diseases. Traditional Chinese medicine utilizes a variety of herbs and natural substances. Each herb/natural substance has its unique characteristics. By combining and balancing the unique characteristics of herbs, a doctor can prescribe a formulation with enhanced medicinal activities and with less or no toxicity by synergizing the medicinal effects among various herbs, while in the meantime, cancelling out or neutralizing the toxic effects of the herbs. This, in Chinese herbal medicine, is regarded as to regulate between negative/hypoactive characteristics ("yin") and positive/hyperactive characteristics ("yang"). Under the definitions set forth in the traditional Chinese medicine, "yin" is defined as drugs which cure cold syndrome (which itself has hot or warm property), and "yang" is defined as drugs which cure heat syndrome (which itself has cold or cool property). The pharmaceutical combination of the present invention comprises fifteen (15) ingredients, in which four (4) ingredients are the core ingredients which contribute to the primary efficacy and healing effect of the composition. They are: (1) diffuse hedyotis/spreading hedyotis (Pharmaceutical name: Herb Hedyotidis diffusae; Botanical name: Hedyotis diffusa Willd.); (2) bistort rhizome (Pharmaceutical name: Rhizoma Bistortae; Botanical name: Polygotiuin bistorta L.); (3) giant knotweed rhizome (Pharmaceutical name: Rhizoma Polygoni Cuspidati; Botanical name: Polygoiiuin cuspidatum Sieb. et Zucc), and (4) Chinese magnoliavine fruit (Pharmaceutical name: Fructus Schisandrae Chinensis; Botanical name: Schisandra chinensis (Turcz.) Baill., S. sphenanthera Rehd. et Wils.). The core ingredients are functioned in dealing heat and toxic substances while improving immune system and circulation, curing symptoms of jaundice, and having beneficial effect on internal organs.

There are six (6) additional ingredients that are used to improve and balance the pharmaceutical activities produced by the above named core ingredients. These six ingredients also have toning effect and can improve blood circulation in the liver. These six ingredients are: (1) Asiatic moonseed ihizome (Phamiaceutical name: Rhizoma Menispermi; Botanical name: Menisermum dauricuiii DC); (2) baical skullcap root (Pharmaceutical name: Radix Scutellariae; Botanical name: Scutellaria baicalensis Georgi); (3) bovine biliary powder (Zoological name: Vesica Fellea Bovus); (4) tumeric root-tuber (Phamiaceutical name: Radix Curcumae; Botanical name: Curcuma wenyujin Y.H. Lee et CI Ling); (5) Hawthorn Fruit (Pharmaceutical name: Fructus Crataegi; Botanical name: Crataegus pinnatifida Bge.); and (6) sanqui (Pharmaceutical name: Radix Notoginseng; Botanical name: Panax notoginseng (Burk.)). Finally, there are additional five (5) ingredients which are used to primarily provide nutrients and energy sources for patients so as to expedite the recovery process. These ingredients include: (1) barbary wolfberry fruit (Pharmaceutical name: Fructus Lycii; Botanical name: Lychim barbarum L.); (3) figwort root (Pharmaceutical name: Radix Scrophulariae; Botanical name: Scrophularia ningpoensis); (4) Chinese angelica (Pharmaceutical name: Radix Angelicae sinensis; Botanical name: Angelica sinensis (01 iv.)

Efficacy of the YGK Herbal Composition on Treatment of Patients with Hepatitis B (HBV) The clinical research was conducted in the Liberty Military Hospital 21 1 in China.

The course of hepatitis B is determined by many factors, including immune response, host genetic factors, and HBV mutations. The chronic hepatitis distinguishes from the acute hepatitis. The acute hepatitis is the active and symptomatic infection of the liver. A patient with the acute hepatitis is contagious. Symptoms of acute HBV infection are non-specific, but may include malaise, anorexia or jaundice. A chroniG hepatitis patient is asymptomatic. The HBV is present in the liver and blood, although there are usually no obvious physical symptoms. Specific blood tests will reveal the presence of the virus, and the patient is also contagious via blood, birth, sex, needles, etc. Cirrhosis is the pathological dysfunctional state of the liver, the hardening of the liver as the result of chronic hepatitis, chronic persistent hepatitis (CPH) and chronic active hepatitis (CAH).

A total of 948 patients with acute HBV, chronic HBV, and liver cirrhosis participated in a clinical comparative study. The patients were divided into two (2) groups. The study group had 642 patients and the comparative group has 306 patients. The data on patients who participated in this study are listed in Table 3. Table 3. Patients Data in the Clinical Study

(* According to the diagnosis criteria of Hepatitis revised at the Shanghai Hepatitis Conference in 1980, Shanghai, China.) The patients were treated according to the following regime:

(1) The patients in the study group were each orally administered eight (8) YGK herbal composition containing the herbal composition of the present invention per day.

(2) The patients in the comparative group were each orally administered four (4) Hugang ("liver protecting") tablets per day. A description of Hugang tablets has been provided in the "Background" section, supra.

The treatment lasts for ninety (90) days. Table 4 shows the results of this clinical comparative study. Table 4. Effects of YGK Capsule Treatment

(pO.01)

: Positive effect means that the hepatitis B envelope antigen (HBeAg) and HBV DNA of the patients turn negative after taking the YGK herbal composition for 90 days.

As indicated in Table 4, approximately 71.03%) of patients who took the YGK herbal composition for 90 days show positive responses to the herbal composition. This is contrary to the comparative group where the patients were given a popular "liver protecting" tablets which were available in the Chinese market. Patients who had taken the "liver protecting" tablets only have an effective rate of approximately 33.98% to show improvement in their liver diseases.

The Hepatitis B virus (HBV) consists of a surface and a core. The core contains a DNA polymerase and an e antigen. The DNA structure is double stranded and circular. HBV has four (4) genes encoding four (4) polypeptides: the S (sui face), the C (core), the P (polymerase), and the X (transcriptional transactivating). The S gene consists of three (3) regions, the pre-Sl region, the pre-S2 region, and the region that encodes the surface protein (HBsAg). Very rarely a mutation occuis in the S gene which aborts the production of HBsAg so that a person maybe HBsAg negative but still has the virus present as determined by HBV DNA. In addition, the HBsAg particles are antigenically complex and the antigenic determinants have been identified as one single common determinant designated a, and four (4) major subdeteπninants designated as d, y, w, and r. Thus, the four (4) major determinants are adw, adr, ayw, and ayr.

The C gene consists of two (2) regions, the pre-core region and the core region, which encodes for two different proteins, the core antigen (HBcAg), and the e antigen (HBeAg). A mutation in the pre-core region may stop the production of HBeAg, thus, a person maybe HBeAg negative, but HBsAg positive and HBV DNA positive. Another type of mutant in the core region is called HBV2. The patients that have HBV2 mutant are HBsAg positive but lack HBeAg and HBV DNA.

Because of the complexity and the antigenic differences among the virus, there are a number of tests available for HBV including:

(1) a test for HBsAg, which is an indicator of the presence of the HBV;

(2) a test for HBeAg, which correlates with the viral replication and infectivity, it indicates a high amount of the virus in the blood, thus, is an indicator of the activity and infectivity of the HBV; and (3) a test for HBV DNA, which is an indication of the virus presence and activity.

Tables 5-7 indicated the change of Hepatitis B envelope Antigen ("HBeAg"), Hepatitis B surface antigen ("HBsAg"), heptomegaly, and splenomegaly in the patients after the treatment.

Table 5. Effect of Herbal Composition on HBeAg in Patients

As indicated in Table 5, the percentages of patients with HBeAg turning negative in all three (3) categories of patients (including acute hepatitis, chronic hepatitis, and cirrhosis) are 2J-3.3 times higher than those of the comparative groups. This demonstrates that the YGK herbal composition had significant effect on HBeAg turning negative and inhibiting HBV activity and infectivity.

Table 6. Effect of Herbal Composition on HBsAg in Patients

As indicated in Table 6, the percentages of patients with HBsAg turning negative in all three (3) categories of patients including acute hepatitis, chronic hepatitis, and cirrhosis were 3.1-4.4 times of those of the comparative groups. This demonstrates that the YGK herbal composition had significant effect on HBsAg turning negative and inhibiting the HBV.

In addition to HBeAg and HBsAg turning negative, the YGf herbal composition also show greater effects on increased appetite and decreased various symptoms of liver diseases than the comparative group using Hugang "liver protecting" tablets.

Table 7. Effect on Hepato-Splenmegaly

Heptomegaly and splenomegaly are related to and possibly Gaused by viral infection.

The reduced hepatomegaly and splenomegaly in patients was indicative to reduced symptoms of viral infection.

In summary, the YKG herbal composition demonstrates effect on treating patients with HBV, which including acute hepatitis B, chronic hepatitis B, and cirrhosis. Example 3

Effects of the YGK Herbal composition on Treatement of Patients with Chronic Hepatitis B (HBV)

The clinical research was conducted in the Liberty Military 302 Hospital, Ninth

Section, China. The research was conducted on treatment effects of the herbal composition of the present invention on chronic hepatitis B patients.

Chronic Hepatitis is an ongoing injury to the cells of the liver with inflammation which lasts for longer than six months. The causes of chronic hepatitis include: viruses, metabolic or immunologic abnormalities and medications. Symptoms resulted from the injury of hepatocytes, the inflammation or from the resulting scarring is called Girrhosis. ChroniG hepatitis may follow acute hepatitis B or C or may develop quietly without an acute illness. Liver biopsy is helpful in that it confirms the diagnosis, aids in establishing the cause

(etiology) and can demonstrate the presence of cirrhosis. It is less helpful in judging the response to treatment. Approximately 25% patients with chronic hepatitis B will develop

Girrhosis, causing permanent and serious liver damage. Chronic carriers of HBV are far more likely to develop hepatocellular carcinoma than non-carriers. It is believed that chronic infections develop as the result of a weak T helper (Th) cell response to the virus, in particular to the HBsAg. The T cell response is responsible for clearing the infected cells in the host's system. When the clearance is inefficient and the infected cells persist in the body, a Ghronic infection develops. As the HBsAg tiler increases, the patient moves into acute, symptomatic disease. When the liter of anti-HBsAg rises, the symptoms of HBV begin to decline and patient reaches the immune state.

Chronic hepatitis has been divided into two categories based on histologic findings: chronic persistent hepatitis (CPH) and chronic active hepatitis (CAH). Characteristically, specimens from liver biopsy identified as CPH show inflammation confined to the portal triad (does not penetrate the limiting plate). Specimens identified as CAH show inflammation that penetrates the limiting plate, extending to the surrounding individual hepatoGyte and yielding piecemeal necrosis. Under this schema, CAH eventually readies a point where lobular architecture is destroyed, and bands of necrosis (bridging necrosis) are replaced by scar tissue (bridging fibrosis), resulting in the characteristic features of cirrhosis.

Sixty (60) patients with chronic hepatitis B are divided into two (2) groups, one group for treatment with YKG herbal composition and the other with Hugang ("Liver protecting") tablets. The study was conducted and maintained for three (3) months. The patients information in the two (2) groups are shown in Table 8:

Table 8. Compositions of the Patients in the Clinical Study

in 1980. Table 9 shows the changes in HBsAg, HBeAg, and HBV-DNA in patients after treatment with the YGK herbal composition (the study group) or Hugang tablets (the comparative group).

As indicated above, HBsAg can be detected in patients with acute infection as well as patients who are chronic HBV carriers. In the serological test, decreased tiler of HBsAg indicates that the symptoms of HBV are lessened and the patient is approaching the immune state.

Table 9. The Changes of HBsAg. HBeAg, and HBV-DNA in Patients

p< 0.05. As indicated in Table 9, the YGK herbal composition has significant effects on chronic hepatitis patients. Patients treated with the YGK herbal composition have Serum Glutamic Pyruvic Transaminase/Serum alanine aminotransferase (SGPT/ALT) recovery rate of 73.33%, HBeAg turning negative rate of 46.15%, HBV-DNA turning negative rate of 60.00%), suggesting that the YGK herbal composition has significant effects on inhibition of HBV replication and presence and depletion of aminotransferase. In addition, there was no toxic adverse reaction on the patients treated with the YGK herbal composition, accodring to clinical obervation.
