Journal of Medical Research 2007;49(3):90-95
Background: AH product is a herbal remedy containing of twelve plant extracts, which has a good hepatoprotective effect in two models inducing acute liver injury by carbon tetraclorid (CCl4) and paracetamol. Objective: To evaluate antioxidant activity in vitro and in vivo of AH product. Subjects and methods: Evaluation of antioxidant activity through a reduction of anion superoxide level in vitro and MDA concentration in liver tissue in vitro and in vivo. Results: AH product reduced anion superoxide level, IC50 was 26.60\xb5g/ml. In vitro, AH product at concentration of 125\xb5g/ml reduced formation of MDA 53.70%. The higher the concentration, the stronger the inhibition. In vivo, models of acute liver injuries induced by CCI4 and PAR in mice, AH product at two different doses (4.8 tablets/kg and 9.6 tablets/kg) reduced MDA concentration in liver tissue (33,9 - 36,6 % in CCI4 model and 21,4 - 25,3 % in PAR model) in comparison with group which used hepatotoxins but didn't use any drug. Conclusions: AH product containing many remedies was demonstrated having antioxidant activity which contributed to mechanism of hepatoprotection of this product. \r\n", u'\r\n', u'

In traditional medicine, there are many remedies to treat the hemorrhage syndrome in aplastic anemic patients, such as \u201cBao nguyen thang\u201d, \u201cNhi tien thang\u201d, \u201cNhi chi hoan\u201d, \u201cO ke bach Phuong hoan\u201d, \u201cQuy ty thang\u201d herbal remedies\u2026 Objectives: To research the effects of supplemental treatment for hemorrhage syndrome by \u201cDuong quy bo huyet thang\u201d herbal remedy on aplastic anemic patients. Subjects and method: A study was carried out on 60 aplastic anemic patients at Bach Mai Hospital from October 2006 to October 2007. The subjects were divided into two groups: group I was treated with blood transfusion, corticoid and supplemental treatment by \u201cDuong quy bo huyet thang\u201d remedy; group II was only treated with blood transfusion and corticoid. This was a controlled, randomized clinical trial. Results: The average age of the patients was 40.57 +/- 16.77 years in group I and 41.73 +/- 17.14 years in group II (p>0.05). The male-female ratio was 1.07. The number of patients with hemorrhage syndrome decreased from 66.7% to 36.7% after 60 days of treatment.

Background: Peritoneal tuberculosis (PT) and peritoneal malignancy (PM) are the most frequent causes of exsudate ascitic fluid but the different diagnosis between the former and the latter is also difficult and elusive. Objective: To study the difference of clinical and laparoscopic features between PT and PM. Subjects and method: 76 patients with PT and 50 with PM were diagnosed by laparoscopy and peritoneal biopsy. Ascitic mycobacterium tuberculosis was detected by PCR analysis. Exsudate ascites was confirmed according to criteria of Light. Results and Conclusions: Average age of PT was younger than of PM (p < 0.001). The frequency of fever, pleural effusion in the patients with PT was higher than those in PM (p < 0.001 and 0.05). The anemia and abdominal tumefaction in those of PM was more frequent than in those of PT (p < 0.05 and 0.001). High protein ascitic fluid and numerous lymphocytes in the patients with PT was frequent than in those with PM (p < 0.05). Laparoscopic features: In those patients with PT the white "miliary nodules" or adhesions between abdominal wall was more frequent than in those with PM (p < 0,05) and in patients with PM omental thickening, tumor formation was more than in those with PT.

To investigated the protective potential of ethanol extracts of Scutellaria baicalensis (S. baicalensis ) against lipopolysaccharide (LPS)-induced liver injury. Methods: Dried roots of S. baicalensis were extracted with ethanol and concentrated to yield a dry residue. Mice were administered 200 mg/kg of the ethanol extracts orally once daily for one week. Animals were subsequently administered a single dose of LPS (5 mg/kg of body weight, intraperitoneal injection). Both protein and mRNA levels of cytokines, such as tumor necrosis factor alpha, interleukin-1β, and interleukin-6 in liver tissues were evaluated by ELISA assay and quantitative PCR. Cyclooxygenase-2, inducible nitric oxide synthase, and nuclear factor-κB protein levels in liver tissues were analyzed by western blotting. Results: Liver injury induced by LPS significantly increased necrosis factor alpha, interleukin-1β, interleukin-6, cyclooxygenase-2, inducible nitric oxide synthase, and nuclear factor-κB in liver tissues. Treatment with ethanol extracts of S. baicalensis prevented all of these observed changes associated with LPS-induced injury in liver mice. Conclusions: Our study showed that S. baicalensis is potentially protective against LPS-induced liver injury in mice.

Background: With the help of Japan, the Center for Research and Production of vaccines and biologicals, Hanoi has received a WHO standard measles vaccine production technology, including techniques in the examination of vaccine quality. Therefore, it is needed to be initiative on production of measles antibody. Objective: Study on production of measles antibody in rabbits and selecting the appropriate antibody for production of high titre antibody, which meets the standard of vaccine quality control in Vietnam. Subject and methods: Using the measles antigen from Edmonston and AIK-C strains, which were provided by the Kitasato Institute, to produce measles antibody. Making immunoreaction in rabbits and determination of neutralization antibody titre. Results and Conclusion: Measles antigen of Edmonston Vero 7/P2 strain used in the production of measles antibody in rabbit created the highest antibody titre in comparison with AIK-C strain from vero cell and FL cell supplied by the Kitasato Institute of Japan. Antibody titre of Edmonston Vero 7/P2 strain reached up to 1/8192 and met the sera standard required for measles vaccine quality control, it is similar to the measles sera to be produced from the Kitasato Institute.

Objective: To evaluate the antitumor activity both in vitro and in vivo of saponin–phospholipid complex of Panax notoginseng. Methods: The in vitro cytotoxic effect of saponins extract and saponin–phospholipid complex against human lung cancer NCI-H460 and breast cancer cell lines BT474 was examined using MTS assay. For in vivo evaluation of antitumor potential, saponin and saponin–phospholipid complex were administered orally in rats induced mammary carcinogenesis by 7,12-dimethylbenz(a)anthracene, for 30 days. Results: Our data showed that saponin–phospholipid complex had stronger anticancer effect compared to saponin extract. The IC50 values of saponin–phospholipid complex and saponin extract for NCI-H460 cell lines were 28.47μg/mL and 47.97μg/mL, respectively and these values for BT474 cells were 53.18μg/mL and 86.24μg/mL, respectively. In vivo experiments, administration of saponin, saponin–phospholipid complex and paclitaxel (positive control) effectively suppressed 7,12-dimethylbenz(a) anthracene-induced breast cancer evidenced by a decrease in tumor volume, the reduction of lipid peroxidation level and increase in the body weight, and elevated the enzymatic antioxidant activities of su-peroxide dismutase, catalase, glutathione peroxidase in rat breast tissue. Conclusions: Our study suggests that saponin extract from Panax notoginseng and saponin–phospholipid complex have potential to prevent cancer, especially breast cancer.
