A study on hemocyte in peripheral blood of women ages of 18 and above in some suburb communes in Th¸i B×nh province has shown that level of average Hb is about 120 - 130 g/l, highest level of it is in ages of 18 -30 (141, 44 g/l) and lowest in ages of 70 and above (123,66g/l). The rate of subjects with Hb level less than average normal threshold (120% g/l) is 24,76%. This rate is 20,16% in ages of 41 -50 and highest rate is 48,48% in ages of 70 and above mild anemia (most common); moderate anemia: uncommon; and severe anemia: 0.

“Quy ty hoan” is a remedy which is used in traditional medicine as digestive and cardiac tonic. Hemolytic aneamia models on rabbits and malnutrition-bleeding aneamia were used in this study. Results showed Phenylhydrazin and malnutrition-bleeding decreased erythrocyte number and hemoglobin concentration significantly in blood of rabbits. These models could be used in treatment of anemia. “Quy ty hoan” in dose of 8g/kg b.w.per os decreased hemolytic effects of phenylhydrazin and recovered quickly erythrocyte number, hemoglobin concentration and increased albumin and iron in blood after malnutrition bleeding.

The research was conducted on the women with anemia from Vu Hoi, Vu Thu, Thai Binh. The participants, with age ranged from 18-49 years, were divided into 2 groups. One group was given Quy Ty pills and other received iron pills. The diet of participants was not directed. Rate of hematological symptom resolution (74.5%) in Quy Ty group and (51.4%) in iron pill group was higher than placebo group. Rate of serum iron and ferritin deficiencies was lowered significantly in both Quy Ty and iron pill groups.

The aim of this study is to delineate ‘admixed hybrid’ and ‘introgressive’ Fasciola genotypes present in the Fasciola population in Vietnam. Adult liver flukes collected from ruminants in 18 Provinces were morphologically sorted out by naked eyes for small (S), medium (M) and large (L) body shapes; and human samples (n=14) from patients. Nuclear ribosomal (rDNA) ITS1 and ITS2, and mitochondrial (mtDNA) nad1 markers were used for determination of their genetic status. Total 4,725 worm samples of ruminants were tentatively classified by their size: 6% (n=284) small (S)-, 13% (n=614) medium (M)-, and 81% (n=3,827) large (L)-forms. All the representative (n=120, as 40 each group) and 14 human specimens, possessed maternal mtDNA of only F. gigantica and none of F. hepatica. Paternally, all (100%) of the L-(n=40) and 77.5% (n=31) of the M-flukes had single F. gigantica rDNA indicating ‘pure’ F. gigantica. A majority (90%, n=36) of the S- and 15% (n=6) of the M-worms had single F. hepatica rDNA, indicating their introgressive; the rest (10%, n=4) of the S- and 7.5% (n=3) of the M-flukes had mixture of both F. gigantica and F. hepatica rDNAs, confirming their admixed hybrid genetic status. Fourteen human samples revealed 9 (64%) of pure F. gigantica, 3 (22%) of introgressive and 2 (14%) of admixed hybrid Fasciola spp. By the present study, it was confirmed that the small worms, which are morphologically identical with F. hepatica, are admixed and/or introgressive hybrids of Fasciola spp., and able to be the pathogens of human fascioliasis.

Objective: To investigate the cause of a foodborne outbreak that occurred in Dong Nai province, Viet Nam, in 2024, and implement control measures. Methods: An initial investigation was conducted to confirm the outbreak, which was followed by epidemiological and environmental investigations to find the plausible causative food item. Clinical specimens and food samples were tested to identify the pathogen. Results: A total of 547 symptomatic cases were recorded, of whom two were in severe condition requiring extracorporeal membrane oxygenation and ventilation, one of whom died. Among 99 interviewed cases, the mean incubation time was 9 hours (range 2–24 hours), with the main symptoms being fever, abdominal pain, diarrhoea and vomiting. All patients had eaten banh mi from a local bakery. Salmonella spp. were identified in food samples and clinical specimens. The bakery halted production, and the outbreak ended after 1 week. Discussion: All the patients were exposed to only one food in common, which facilitated the investigation process. This outbreak is a reminder to small retailers and take-away shops of the importance of food safety management in preventing similar future outbreaks. All food handlers must comply with food hygiene principles, especially in hot temperatures, which boosts bacterial growth.
