Study on 100 gastroduodenal ulcer patients treated at Can Tho General Hospital between March and December 2001. Results: the prevalence of gastric ulcer was high (58%), followed by duodenal ulcer (39%) and the prevalence of gastroduodenal ulcer was low (3%). The rate of H.pylori positive was 66.66% in duodenal ulcer patients, 55.17% in gastric ulcer patients. The rate of H.pylori infection was 33.33% in gastroduodenal ulcer patients. H.pylori was still sensitive with amoxicillin (97.29%), tetracycline (94.6%), clarythromycine and erythromycin (72.97%), but was highly resistant with metronidazole (91%).

Wound infection is one of the most important surgical infection and is a high percentage of hospital infection. In general surgical deparment at Can Tho General Hospital from 2001-2002, 110 samples of wound infection were isolated and tested antibiogram. Total of 133 microbial strains were isolated, multi infection is 19.09%, the highest of number of bacterial strain in a sample is 3. E. coli is the most common isolated (26.34%), Klebsiella sp 16.55%, Staphylococcus aureus: 9.78%. The result of antibiogram showed that among cocci gram positive group, lowest resistance antibiotic are vancomycin (6.24%), ciprofloxacin (55.3%); among bacilli negative group most of antibiotic tested were resistant in more than 50%, antibiotics nearly completely resistant were ampicillin (95.92%) and amoxicillin+clavulanic acid (82.35%), amikacin (75.29%). For Pseudomonas, antibiotica are still good effect are ciprofloxacin (90%), colistin (80%). Pseudomonas are still reristant to other antibiotics (50-70%).

Background: There are many methods used in epidemiological studies of tuberculosis (TB) bacteria but Spoligotyping method is widely used with high accuracy, simple procedure, and carried out on strains containing a little of IS6110 segment \r\n', u'Objectives: To improve Spoligotyping technique and apply this technique to classify Mycobacterium tuberculosis\r\n', u'Subjects and method: Subjects and methods: The study included 12 medical waste samples collected at Thai Binh Hospital of Tuberculosis and 19 samples obtained from the The Hanoi Institute for Tuberculosis and Lung Diseases. Spoligo model of 31 samples were analyzed based on Spotclust and SpoIDB4 database and divided up into family and subfamily.\r\n', u'Results: Spoligotyping technique has good results with the PCR product amplified 40 cycles and presented the film in 18 hours. Obtained results in 31 medical waste samples belong to 4 families: Beijing, EAI, T1 and H3-LAM9. EAI and Beijing are dominant families with 45.16% and 38.7%), respectively. T1 and H3-LAM9 are 12.9% and 3.22%, respectively. The number of samples in the study is little but the obtained rate of different spoligo models of strains are quite diversified (41.9%)\r\n', u'Conclusion: This result is relatively appropriate with previous studies on the distribution of EAI and Beijing families in Vietnam and the world. Spligotyping technique distinguished samples belonging to Beijing or non-Beijing families, which support for clinical treatment and development of new vaccines.\r\n', u'\r\n', u'\r\n', u'

A new compound, 3β-acetoxylanosta-7,9(11),24-triene-26-al (3), and seven known compounds (1 – 2 and 4 – 8) were isolated from Ganoderma tropicum (Jung.) Bres. collected in Tay Nguyen, Vietnam. The structures of these compounds were determined by one- and two-dimensional nuclear magnetic resonance spectroscopy, electrospray ionization mass spectrometry (ESI-MS), and high-resolution ESI-MS, and by comparison with literature data. All of the isolated compounds were tested for nitroblue tetrazolium (NBT) reduction activity in Saccharomyces cerevisiae-stimulated RAW 246.7 cells. Among them, compounds 2 – 4 and 6 – 8 enhanced the NBT reduction in a dose-dependent manner.

Background: s/Aims: Parenchymal-sparing anatomical hepatectomy (Ps–AH) based on portal ramification of the right anterior section (RAS) is a new technique to avoid unnecessarily transecting too much liver parenchyma, especially in cases of major anatomical hepatectomy. Methods: We prospectively assessed 26 patients with primary hepatic malignancies having undergone major Ps–AH based on portal ramification of the RAS from August 2018 to August 2022 (48 months). The perioperative indications, clinical data, intra-operative index, pathological postoperative specimens, postoperative complications, and follow-up results were retrospectively evaluated. Results: Among the 26 patients analyzed, there was just one case that had intrahepatic cholangiocarcinoma The preoperative level of α– Fetoprotein was 25.2 ng/mL. All cases (100%) had Child–Pugh A liver function preoperatively. The ventral/dorsal RAS was preserved in 19 and 7 patients, respectively. The mean surgical margin was 6.2 mm. The mean surgical time was 228.5 minutes, while the mean blood loss was 255 mL. In pathology, 5 cases (19.2%) had microvascular invasion, and in the group of HCC patients, 92% of all cases had moderate or poor tumor differentiation. Six cases (23.1%) of postoperative complications were graded over III according to the Clavien–Dindo system, including in three patients resistant ascites or intra-abdominal abscess that required intervention. Conclusions Parenchymal-sparing anatomical hepatectomy based on portal ramification of the RAS to achieve R0-resection was safe and effective, with favorable short-term outcomes. This technique can be used widely in clinical practice.
