We report 4 children with encephalitis associated with human bocavirus (HBoV) 1 or 2. All children were severely underweight, and 2 died; 1 of them had a matching HBoV2 nucleotide sequence isolated from serum and bocavirus like particles in the cerebrospinal fluid that were observed with electron microscopy. No further pathogens were detected in the cerebrospinal fluid of these patients. 相似文献

Decreased gastric acid secretion and bacterial colonization of the stomach in severely malnourished Bangladeshi children 总被引:4,自引:0,他引:4

To assess the effect of malnutrition on gastric acidity and gastric bacterial colonization, we studied 35 severely malnourished Bangladeshi children before (0 wk) and after (3 wk) they received nutritional rehabilitation for 3 wk. These results were compared with those obtained from a similarly examined group of 20 better-nourished Bangladeshi children. Gastric acid output, both basal and after betazole stimulation, was significantly lower in the malnourished group at 0 wk compared with the better-nourished children (p less than 0.01): basal 0.22 vs. 0.52 mEq HCl/h and stimulated 0.90 vs. 2.5 mEq HCl/h. Both the concentration of acid and the rate at which gastric juice was secreted were decreased in the malnourished group but serum gastrin levels were not significantly different. After 3 wk, the malnourished children had improved from 61% (+/- 9.0%; SD) to 81% (+/- 8.1%) of expected weight-for-height and were not significantly different than the better-nourished group (86% +/- 11%). Nevertheless, gastric acid concentration remained depressed in the 3-wk group, although the rate of gastric juice secretion equaled levels observed in the better-nourished group. None of the better-nourished children had detectable gram-negative bacterial colonization of their gastric juice. In contrast, 26 of 32 (81%) malnourished children at 0 wk were colonized--even after betazole stimulation, 11 of 33 (33%) gastric juice samples yielded viable organisms--suggesting that the decrease in gastric acid output greatly reduced the gastric acid barrier. Interestingly, only 9 of 20 (45%) better-nourished children had gastric juice with basal pH values below 4.0, suggesting that the gastric acid barrier may be an intermittent defense factor in Bangladeshi children. 相似文献

This paper evaluates the effectiveness of respondent driven sampling (RDS) to sample males who have sex with males (MSM) in
Dhaka, Bangladesh. A major objective for conducting this survey was to determine whether RDS can be a viable sampling method
for future routine serologic and behavioral surveillance of MSM as well as other socially networked, hard to reach populations
in Bangladesh. We assessed the feasibility of RDS (survey duration; MSM social network properties; number and types of initial
recruits) to recruit a diverse group of MSM, the efficacy of an innovative technique (systematic coupon reduction) to manage
the implementation and completion of the RDS recruitment process and reasons why MSM participated or did not participate.
The findings provide useful information for improving RDS field techniques and demonstrate that RDS is an effective sampling
method for recruiting diverse groups of MSM to participate in HIV related serologic and behavioral surveys in Dhaka. 相似文献

A cross sectional work has been done on Bangladeshi females, working in different fibre industries, to study the effect of exposure to fibre dust on pulmonary functions. The ventilatory capacities were measured by VMI ventilometer in 653 apparently healthy women (160, 162 and 167 were jute, textile and garment industry workers, respectively). For the controls 164 females were recruited who never worked in any fibre industry. The observed FVC, FEV1 and PEFR were lower in all groups of fibre industry workers than those of the control. Among the industry workers, the jute mill workers had the lowest ventilatory capacities and garment industry workers had the highest values. The jute and textile mill workers had also significantly lower FEV1 and PEFR than those of garment industry workers. The FEV1 and PEFR were significantly lower in jute mill workers than those of textile ill workers. The low ventilatory capacities were almost proportionate with the length of service of the workers. Thus, the present study indicates that the fibre dust, on regular exposure for longer duration, may limit the lung functions. 相似文献

A series of new steroidal pyrazolones have been synthesized, characterised and evaluated for their in vitro anticancer activity. They were tested against five cancer (SW480, HepG2, A549, HeLa and HL-60) cell lines. The synthesized compounds showed high selectivity and compound 4 showed the strongest inhibitory activity against human SW480 (IC50 = 11.67 μmol L?1). In addition, the synthesized compounds were tested for their antimicrobial activity by disc diffusion assay and MIC by broth micro dilution method against Gram-positive, Gram-negative strains of bacteria as well as fungus strains and we found a correlation between the observed and predicted antimicrobial activities. Docking studies were performed to investigate the hypothetical binding mode of the target compounds. This study provided a new molecular scaffold for the further development of anticancer as well as antimicrobial agents. 相似文献

Allergic Rhinitis (AR) is one of the most common chronic diseases in the developed countries. This study was performed to investigate the effect of CpG-ODN in alteration of T-helper (Th)1/Th2 balance of patients with AR treated with intranasal corticosteroids (INCs) and antihistamines. Peripheral blood mononuclear cells (PBMCs) of 20 patients with AR were isolated before and after 45 days therapy. Cytokine production (IL-4, IL-10, IL-13, IFN-γ) and specific Ch.a IgE in response to CpG co-administration of natural chenopodium album (CpG/Ch.a) or recombinant Ch.a (CpG/rCh.a) allergen were investigated in supernatants.of cultured PBMCs using ELISA Intracellular IL-10 was also assessed in CD4+ cells using flow cytometry. Significant increase in production of IFN-γ and IL-10 and decrease in production of IL-4 were found in supernatants of cultured PBMCs activated with CPG/ch.a and CPG/rch.a. of both CpG/Ch.a and CpG/rCh.a compared to allergens alone, before and after therapy. After therapy, IFN-γ production with CpG/Ch.a was significantly increased in comparison with before (237 vs. 44 pg/ml, p=0.001). IFN-γ and IL-10 production with CpG/rCh.a was significantly increased after therapy compared to before (407.6 vs. 109 pg/ml, p=0.01 for IFN-γ; 171.7 vs. 52.6 pg/ml, p=0.008 for IL-10), whilst IL-4 was significantly decreased (2.1 vs. 5.8 pg/ml, p=0.02). Intracellular IL-10 expression was also significantly increased in response to either CpG/Ch.a or CpG/rCh.a that showed intracellular assay could be more sensitive than ELISA. Also, treatment with intranasal corticosteroids and antihistamines could enhance this CpG effect, in vitro. 相似文献

Human immunodeficiency virus (HIV) infection has been spreading rapidly in the developing countries and vertical transmission also taking place. This study has been done to find out the prevalence of HIV infection among the pregnant women, so that necessity of routine screening test can be identified. It is a cross sectional study. Five hundred two pregnant women were included. Three ml venous blood was taken and then HIV screening test was done by ELISA method. All reactive tests were confirmed by Western blot antibody testing. The positive cases were followed up and necessary treatment was given. Delivery was conducted in this hospital. Baby's blood was tested to see vertical transmission after 18 months. Most of the subject were educated housewife, mean age was 25 years. Six (6%) husband was overseas service holder, 12% were smoker and 1.6% had drug addiction. Eight (8%) subject had previous history of blood transfusion and 49% subject or her husband had history of surgery or got parental therapy. 2% subject gave the history of familial disharmony and 2% had multiple sex partners. HIV infection was found in 2 patients (0.4%). Both of them got infection from their husband. One husband was over seas service holder and another one was injecting drug user. For the prevention of spread, reduction of vertical transmission and providing early management to the positive patient all pregnant women should be screened for HIV routinely. 相似文献
