2 group of 45 women each, 60-70 years of age, were recruited for this study during 6 months. All women did morning physical exercise regularly. The first group received a daily suplementation of 50g biscuits cotaining 400mg calcium gluconate and the second group received the same amount of biscuits without calcium addition. The bone mineral density was measured at baseline and after 6 months. The results: in the calcium group, there was a significant increase of bone mineral density compared to the control group. The mean systolic and mean diastolic blood pressures found decreased in the calcium group and increased in the control group.

A public nutritional intervention trial on 45 women (ages of 60-70) by using the calcium complemented cakes and 45 women by using common cakes in Namdong and Giang vo communes, Hanoi capital aimed at evaluating the bone density and cardiovascular indices after intervention. The results have shown that the use of calcium supplemented cakes increased the T score of 0,1g/cm2 in the arm and T score of 0,17g/cm2 in the leg of menopausal women and reduced the systolic and diastolic pressure 2,9mmHg and 3,9 mmHg, respectively.

Introduction: Diabetes is a serious metabolic disease with chronic and acute complications, especially atherosclerosis. The increase of blood homocystein level is obviously related to blood injuries\u2019 in a number of diseases including diabetes. In Vietnam, blood Homocystein in Diabetics has not been comprehensively studied. \r\n', u'Objectives: The study was conducted with two surveyed groups. Determination of blood homocystein concentration in type 2 diabetics in comparison with a group of normal people. \r\n', u'Subjects and method: The study was conducted on a sample of 57 type 2 diabetics according to WHO-2001 standards and a group of 46 normal people. Concentration of blood homocystein was assayed by a competition fluorescence immunoassay, and by other experiments according to normal biochemical methods.\r\n', u'Results: The tHcy concentration in diabetics is 12.19 \xb1 3.47 mmo/L and in the normal group is 7.87 \xb1 2.26 IJmo/L. \r\n', u'Conclusion: The tHcy concentration in the 57 type 2 diabetics group has a statistically increasing mean in comparison with the normal group for both men and women. However, there is no comparative difference in the tHcy concentration of diabetics in gender and age categories. \r\n', u'

Background: Morphological structure of dental enamel-cement border of the 7th tooth is of great interest to many dentists with various different meanings. Study of the border of the 7th tooth allows the visual description of the morphological structure of this region. Objectives: To highlight the structure of dental enamel-cement border as well as its application in the endodontic treatment. Subjects and methods: The team used screening electronic microscopy to investigate the morphology and structure of twenty, second molar of adults who are between 18 and 35 year old. These teeth were extracted due to dental correction or caries (on chewing face). The study was conducted on both non-demineralized and demineralized teeth. Results: There are 3 kinds of connection in the enamel-cement border area of second molar: cement covering enamel, enamel-mineralized peridental ligament there is a gap between enamel and cement without exposing dentine. The kind of cement covering enamel connection is characteristic for dental interior face. The kind of enamel-mineralized peridental ligament is characteristic for the proximal, distal and middle dental face, the kind of enamel and cement without exposing dentine is characteristic for external face. Conclusion: Research conducted on only a small amount of tooth No. 7, further studies should be carried out on other teeth to have a more accurate description. \r\n', u'\r\n', u'

Background:Cerebral vasospasm is a proved reaction and nimodipin revolutionised the treatment of subarrachnoid hemorrhage in adult. However, the effectiveness of Nimodipin in cerebral vasospasm remained controversial in intracranial hemorrhage (lCH) in children. Objectives:This study aims to estimate the effectiveness of nimodipin in treatment of children with intracranial hemorrhage.Subjects and method:A descriptive, prospective study was conducted on all children patients diagnosed intracranial hemorrhage and treated at Neurology department of National Hospital for Pediatric, Vietnam from 2004 to June 2007. They applied the Transcranial Doppler sonography (TCD) in diagnosis of vasospasm in intracranial hemorrhage in children and follow-up the evolution after treatment with nimodipin. Results:The results showed that cerebral vasospasm with hight resistance index (RI) on TCD (RI = 0.78 \xb1 0.08) and cerebral ischemie with low systolic velocity (Vs = 68 \xb1 12.2 crn/s) and hight pulsality index (PI = 1.4 \xb1 0.13) were observed in 100% of cases after 3 days with ICH. Nimodipine improved clinical status (71.2%) and CT scan (52%), also RI, PI, Vs returned to normal when used nimodipin within 7 days of ICH. Conclusion: The treatment method for intracranial hemorrhage with nimodipin supplement had proved to have initial effecacy in comparison with traditional method.

Background: Irritable bowel syndrome is a diagnosis of exclusion. It is a functional bowel disorder characterized by chronic abdominal pain, discomfort, bloating, and alteration of bowel habits in the absence of any detectable organic cause."Tu than hoan" is a traditional remedy applied for the treatment of syndromes of traditional medicine which have the similar characteristics to irritable bowel syndrome of diarrhea state of modern medicine. Objectives: The study had two purposes: (1)To evaluate the therapeutic effects of the remedy on the clinical symptoms of patients with irritable bowel syndrome of diarrhea state comparing with Duspatalin; (2)To evaluate the side effects of the remedy. Subjects and method:162 patients diagnosed with irritable bowel syndrome of diarrhea state were treated at Bach Mai hospital from March to August 2005. They divided into 2 groups, the control group included 77 patients and the study group included 85 patients. : clinical test, comparing with controls. Results: 80% of patients recovered from diarrhea; 82.4% of patients with defecation returned to normal; 93.6% stopped mucous feces; 76.5% stopped bellyache. Good therapeutic effect was 61.2% (p < 0.05). Conclusions: Tu than hoan had good therapeutic effects in the treatment of irritable bowel syndrome of diarrhea state. None of patients had to discontinue the medicine due to side effects. \r\n', u' \r\n', u'

Background: In traditional medicine, liquid extract VK2 has good effects in the treatment of osteoarticular pain. This remedy has its origin from \u201cTam ty thang\u201d of the Eastern traditional medicine. Objective: To evaluate the analgesic and acute anti-inflammatory effects of liquid extract VK2. Subjects and method: The trial was performed on white mice (18-22 g body weight) and albino rats (120 +/- 20 g body weight). These animals were healthy. The prescribed amount of VK2 doses were 27.5 g and 55 g per kg body weight of the mice, 19.25 g and 38.5 g per kg body weight of the rats. Results: The liquid extract of VK2 doses had analgesic effect on acetic acide and themal-induced pain in the mice. The liquid extract of VK2 doses had also acute anti-inflammatory effect through inhibiting carrageenine-induced edema in the hind paw. Conclusion: VK2 had analgesic and anti-inflammatory effects on experimental animals.

We demonstrate that glycoprotein isolated from Dioscorea batatas (GDB) has immunostimulatory effects including macrophage activation. Analysis of infiltration of inflammatory cells into peritoneal cavity showed GDB treatment significantly increased the recruitment of macrophages, lymphocytes, neutrophils, and monocytes into the peritoneal cavity. Treatment of spleen cells isolated from C57BL/6 mice with GDB significantly increased the proliferation of B cells and T cells induced by LPS and ConA, respectively. Treatment with GDB significantly increased the cytolytic capacity of NK cells and macrophages against YAC-1 and B16 cells, respectively. In order to further confirm and investigate the mechanism of GDB on macrophage activation, we analyzed the effects of GDB on the cytokine expression including iNOS, IL-1beta, and TNF-alpha in mouse macrophage cell line, RAW 264.7 cells. RT-PCR and ELISA showed that GDB increased the expression of IL-1beta, and TNF-alpha, whereas iNOS was not induced by GDB. Collectively, this series of experiments indicates that GDB stimulates immune system including macrophage activation.
