Learng Pid Samud (LPS) recipe is a traditional remedy in Thai folk medicine to ease the common diarrhea. The anti-diarrheal potential of LPS recipe was herein examined in vitro using a guinea-pig ileum model. The LPS exerted an inhibitory effect on acetylcholine-induced smooth muscle contraction in the guinea pig ileum. Significantly, not only did the LPS reduce the total amount of feces in the induced diarrhea rats, but also the intestinal transit in the charcoal meal test. A single oral administration with the recipe at 5,000 mg/kg did not cause acute toxicity and the daily oral administration (1,000, 2,000 and 4,000 mg/kg) for 90 days in rats did not produce any toxic signs and symptoms. In conclusion, the Learng Pid Samud recipe remedy is evidently safe and effective for the anti-diarrheal treatment which supports its therapeutic uses in the alternative medicine. 相似文献

In order to characterize A/H5N1 viral sequences, a bioinformatics approach accurately identified viral sequences from discovery of a sequence signature, which provided enough distinctive information for sequence identification. Eight highly pathogenic H5N1 viral isolations were collected from different areas of Thailand between 2003 and 2006, and were used for analysis of H5N1 genotypic testing with a semiconductor-based oligonucleotide microarray. All H5N1 samples and H1N1, H4N8 negative controls were correctly subtyped. Sensitivity of the eight oligonucleotide probes, with optimized cut-offs, ranged from 70% (95% CI 65–75) to 87% (95% CI 84–91), and the corresponding Kappa values ranged from 0.76 (95% CI 0.72–0.80) to 0.86 (95% CI 0.83–0.89). Semi-conductor-based oligonucleotide array and oligonucleotide probes corresponded well when detecting H5N1. After fully correcting the subtype from the result of microarray signal intensity, the microarray output method combined with bioinformatics tools, identified and monitored genetic variations of H5N1. Capability of distinguishing different strains of H5N1 from Thailand was the outstanding feature of this assay. Ninety percent of HA and NA (4/5) genes were sequenced correctly, in accordance with previous examinations performed by classical diagnostic methods. The low-medium-high bioinformatics resolutions were able to predict an epidemic strain of H5N1. This study also showed the advantage of using a large genotypic database to predict the epidemic strain of H5N1. However, the monitoring protocol of this new strain has been recommended for further study with a large-scale sample. 相似文献

Two distinct clinical patterns, encephalitic (furious) and paralytic (dumb), have been recognized in human rabies. It has been postulated that different rabies virus variants associated with particular vectors may be responsible for these different clinical manifestations. Analysis of the glycoprotein (G), nucleoprotein (N), and phosphoprotein (P) genes of rabies viruses from 2 human cases of encephalitic rabies and from 2 human cases of paralytic rabies demonstrated only minor nucleotide differences. Deduced amino-acid patterns of the N protein were identical in both human and canine samples that came from the same geographic location, regardless of the clinical form. All differences in amino-acid patterns of the G protein were found outside the ectodomain, in either the signal peptide or the transmembrane and endodomains. None of the amino-acid differences of the P protein was within the interactive site with dynein. These findings support the concept that clinical manifestations of rabies are not explained solely by the associated rabies virus variant. 相似文献

In the age of a pandemic, such as the ongoing one caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the world faces a limited supply of tests, personal protective equipment, and factories and supply chains are struggling to meet the growing demands. This study aimed to evaluate the efficacy of specimen pooling for testing of SARS-CoV-2 virus, to determine whether costs and resource savings could be achieved without impacting the sensitivity of the testing. Ten previously tested nasopharyngeal and throat swab specimens by real-time polymerase chain reaction (PCR), were pooled for testing, containing either one or two known positive specimens of varying viral concentrations. Specimen pooling did not affect the sensitivity of detecting SARS-CoV-2 when the PCR cycle threshold (Ct) of original specimen was lower than 35. In specimens with low viral load (Ct > 35), 2 of 15 pools (13.3%) were false negative. Pooling specimens to test for Coronavirus Disease 2019 infection in low prevalence (≤1%) areas or in low risk populations can dramatically decrease the resource burden on laboratory operations by up to 80%. This paves the way for large-scale population screening, allowing for assured policy decisions by governmental bodies to ease lockdown restrictions in areas with a low incidence of infection, or with lower-risk populations. 相似文献

Monomorphic epitheliotropic intestinal T‐cell lymphoma (MEITL), also known as Type II enteropathy‐associated T‐cell lymphoma (EATL), is an aggressive peripheral T‐cell lymphoma. EATL generally presents in adults with gastrointestinal symptoms. Skin involvement is very rare, found only in approximately five percent of patients. The authors report a 67‐year‐old Asian male who presented with chronic diarrhea and developed erythema multiforme‐like cutaneous lesions. A skin biopsy revealed extensive pagetoid spread of atypical lymphocytes in the epidermis. The results of an immunohistochemistry test led to a diagnosis of MEITL. This report points to the need for dermatologists and dermatopathologists to consider a possible diagnosis of MEITL when encountering similar cases. 相似文献
