In this research, 67 patients with acute viral hepatitis are divided in two groups: one group of 33 patients used Chµm TÝa infusion, the other of 34 patients didn't use it. We studied both their clinical and paraclinical changes and made the comparisons. The results are shown as follows: Good effect has been demonstrated in the group of moderately severe patients with typical acute viral hepatitis at dose of 90g of fresh leaves. Chµm tÝa has decreased more rapidly these symptoms: tiredness, poor appetite, dyspepsia, jaundice. These improvements are significant with p< 0.05. Chµm TÝa has normalized the total bilirubinemia, ASAT, ALAT, more rapidly in comparison with the control group and it has shortened significantly the treatment course (p<0.05).

The study was conducted on the morphological and epidemiological characteristics of 7 types of viral hepatitis including A,B,C,D,E,G,TTV and a multi-infected hepatitis (infected by C and B virus). The prevalence of various type were different between various areas because of diverse factors of social, economy and living customs, these prevalences were higher in developing countries than developed countries

The diagnosis of viral hepatitis were based mainly on the determination of inflammation status and the necrosis of liver cells, the ruling out of non-viral causes of inflammation such as INH, acetaminophen, pneumococcus,…, and the examinations of epidemiology, clinics, biochemistry, immunology and micrology. The classification of the causes of viral hepatitis relies mainly on the serological, immunological and microbiological tests

30 patients with the active chronic hepatitis B and 30 patients with the ascitic cirrhosis due to hepatitis B from the Army Central Hospital 108 and the National Institute of Clinical Medicine and tropical diseases participated to a study. The results have shown that the coagulation factors II, V, VII, and X in patients with the active chronic hepatitis B were moderately reduced during the exacerbation of the disease and gradually recovered to a normal level or almost normal level during the stable disease. While these factors in the patients with ascitic cirrhosis were severely, unreversible reduced through the progress of disease. During the exacerbation of the diseases. The extend of reduction of the above coagulation factors in patients of the ascitic cirrhosis was more severe than these in patients with the active chronic hepatitis B.

A cross-sectional study was performed from April to December 1999 to evaluate the changes in antibody levels after HBV infection. 242 medical students were screened. Among these, 49 students (mean age 20.7+/-1.25 years, weight 52.3+/-8.1kg) were infected with wild HBV, as confirmed by presence of anti-HBs and anti-HBc and absence of HBsAg. In the first visit, the mean serum concentration of anti-HBs was 323mUI/mL. After 9 months, there was insignificant change in this antibody level with the mean was 303mUI/mL (p=1).

An analysis of 58/218 patients with the possitive HBsAg(+) consulted in the Ngoc Khanh medical and health advice center was implemented. The objective of the study was to find the clinical and paraclinical features, discuss some aspects of the early detection according to the a typical symptoms, the high rate of both HBsAg (+) and antiHBs(+) as well as the transmission resources and treatment in the future.

The most common infected disease in the world in known as hepatitis virus, especially hepatitis B virus (HBV). Vietnam is a country that has a high ratio of HBV infected people. In this experiment, we tested 927 workers from 18 to 25 years old. HBsAg, detected by ELISA techniques, is used by many researcher as a sigh to detect nonsymptom HBsAg carries. The common HBsAg ratio is 3.56%. The highest infected aged group ranged from 20 to 30 years old (3.96%). The lowest aged group up to 20 years old (2.00%). The HBsAg(+) ratio of male (4.31%) is higher than of female (1.74%) with p<0.05. Hanoi is the city that has the lowest HBsAg (+) ratio (2.73%), and Ha Tay is highest (5.17%).

An investigation were carried out on 42 patients of acute hepatitis B (male: 34; female: 8; age: 17-50) at Institute of Clinical Medicine and Tropical Diseases from May to Dec, 1997. Hematology biochemistry tests are determined. The results: the increased concentration of AFP in serum of acute hepatitis B patients (87,95 +/_ 12,89 ng/ml) in compared with normal person. The high level of AFP of 10ng/ml on 20/42 patients (47, 6%). There is a correlation of AFP level, transaminase with AST in the phases I and III and ALT in the phases III. AFP correlates with bilirubin TP during acute hepatitis.

Hepatitis B is a common disease in Vietnam; 15-20% of population carries HbsAg. The investigation of etiology and prognosis should consider the circulate immunal complex (CIC). A study on 65 patients with ages of 17-60 in the Institute of Clinical Medicine and Tropical Diseases during 1997-1998 has shown that the CIC in patients with acute hepatitis B was significantly increased comparing with this normal people. 63% of patients with acute hepatitis B experienced the increase of CIC 250. There was a relation between CIC and some hepatic functional tests in the same time.

A study aimed to compare some clinical features and hepatic functional tests in patients with common acute hepatitis B and patients with long-lasting acute hepatitis B from which to find factors that contributing to prognosis of hepatitis B. 101 patients with ages of 16-30 in the Institute of Clinical Medicine and Tropical Diseases during 9/1997 -10/1998 participated to the study have shown that the most of patients had a moderate disease and disease's symptoms were improved within 6 weeks. The disease occurred in men higher than in women. The duration of before jaundice in patients with common acute hepatitis was shorter than this in patients with long-lasting acute hepatitis B. The clinical symptoms in patients with the long-lasting acute hepatitis B were tired, small liver, edema in limbs, ascities and hepatic coma.
