Pro-inflammatory mediators produced during inflammatory response have been demonstrated to initiate and aggravate pathological
development of several chronic diseases. Plant bioactive constituents have been reported to exert anti-inflammatory activities.
Various parts of Moringa oleifera have long been used as habitual diets and traditional remedy along the tropical region. Anti-inflammatory activity of boiled
M. oleifera pod extract was assessed by measuring pro-inflammatory mediator expression in the lipopolysaccharide-induced murine RAW264.7
macrophage cells. Prior treatment with 31–250 μg/mL M. oleifera extract for 1 h inhibited elevation of mRNA and protein level of interleukine-6, tumor necrosis factor-alpha, inducible nitric
oxide synthase, and cyclooxygenease-2, induced by lipopolysaccharide for 24 h in a dose-dependent manner. The suppressive
effect was mediated partly by inhibiting phosphorylation of inhibitor kappa B protein and mitogen-activated protein kinases.
These results indicate that the anti-inflammatory activity from bioactive compounds present in the M. oleifera pod constituents may contribute to ameliorate the pathogenesis of inflammatory-associated chronic diseases. 相似文献

Methylmalonic acidemia is an inborn error of organic acid metabolism resulting from defects in methylmalonyl CoA mutase. Analysis of plasma free amino acids in a 15-month-old Thai infant by HPLC showed marked elevation of glycine. HPLC analysis of urinary organic acids showed high levels of methylmalonic acid. 相似文献

The incidence of inborn errors of metabolism (IEM) in Thailand is yet unknown. However, by estimation it is generally accepted to be 1 in 5,000. From a survey in 7 medical schools from different parts of the country and a large pediatric hospital in Bangkok, we found numerous cases of IEM nationwidc. Thesc were amino acid disorders, carbohydrate disorders, urea cycle defects, peroxisomal, lysosomal storage disorders, and many others. Since Thais are quite homogeneous in their genetic make-up; it is, therefore, very likely that IEM is much more prevalent than we realized. With the exception of thalassemias, IFAM is probably very common in Thailand and other countries in the Asia-Pacific region. IEM identified were amino acid disorders eg phenylketonuria, maple syrup urine disease: urea cycle disorders eg ornithine transcarbamylase deficincy (OTC), argininosuccinic lyase deficiency (ALD), argininosuccinic acid synthetasc deficiency (ASD); glycogen storage disorders eg Pompe's discase, Von Gierkc's; organic acid disorders eg, isovaleric acidemia, methylmalonic acidemia. Lysosmal storagc disorders identified were GM1 gangliosidosis, mucolipidosis II, Hurler, Hunter, Maroteaux-Lamy, Sialidosis (neuraminidase deficicncy), Sly, Scheie, Gaucher, Niemann-Pick, Sandhoff and many other neurodegeneraative disorders identified were rhizomelic chondrodysplasia punctata (RCDP) and Zellweger. Recently fatty acid oxidation disorders: MCAD, translocase deficiency and multiple carbosxylase deficiency 9biotinidase deficiency) were also identified. 相似文献

Correct human beta-globin mRNA has been restored in erythroid cells from transgenic mice carrying the human gene with beta-globin IVS2-654 splice mutation and from thalassemia patients with the IVS2-654/beta(E) genotype. This was accomplished in a dose- and time-dependent manner by free uptake of morpholino oligonucleotide antisense to the aberrant splice site at position 652 of intron 2 in beta-globin pre-mRNA. Under optimal conditions of oligonucleotide uptake, the maximal levels of correct human beta-globin mRNA and hemoglobin A in patients' erythroid cells were 77 and 54%, respectively. These levels of correction were equal to, if not higher than, those obtained by syringe loading of the oligonucleotide into the cells. Comparison of splicing correction results with the cellular uptake of fluorescein-labeled oligonucleotide indicated that the levels of mRNA and hemoglobin A correlate well with the nuclear localization of the oligonucleotide and the degree of erythroid differentiation of cultured cells. Similar but not as pronounced results were obtained after the oligonucleotide treatment of bone marrow cells from IVS2-654 mouse. The effectiveness of the free antisense morpholino oligonucleotide in restoration of correct splicing of IVS2-654 pre-mRNA in cultured erythropoietic cells from transgenic mice and thalassemic patients suggests the applicability of this or similar compounds in in vivo experiments and possibly in treatment of thalassemia. 相似文献

Neonatal screening for phenylketonuria (PKU) was introduced as a pilot project in Thailand from 1992--1995, and mass screening was started in 1996 by the Department of Medical Sciences, Ministry of Public Health. Blood samples were collected by heelprick on filter paper either at 48 hours of life or before discharge from the hospital. Elevated blood phenylalanine was identified by screening with the Guthrie method, then followed by the fluorometric method: All infants with a phenylalanine level equal to or greater than 4 mg/dl were recalled and retested using the fluorometric method and confirmed by plasma amino acid analysis and urinary pterins for tetrahydrobiopterin deficiency. A total of 1,062,676 newborns were screened from October 1992--March 2001, with 5 cases confirmed with PKU. The incidence was 1 in 212,535. All patients have been treated with low phenylalanine diet. The results of this study confirm the benefit of early detection and treatment of PKU through the screening program. 相似文献

Hb Constant Spring [Hb CS, α142(H19)Term] and Hb Paksé [α142(H19)Term] occur from the mutation in the termination codon of the α2-globin gene, TAA>CAA (→Gln) and TAA>TAT (→Tyr), respectively. They are the most common nondeletional α-thalassemia (α-thal) variants causing Hb H disease in Southeast Asia. In this study, 587 cord blood samples were screened for the Hb CS and Hb Paksé mutations by a dot-blot hybridization technique using oligonucleotide probes specific for each mutation. The results showed that the prevalence of Hb CS and Hb Paksé in Central Thailand are 5.80 and 0.51%, respectively, which is in concordance with the results from previous studies. 相似文献

Remarkable improvements in public health, nutrition, hygiene, and availability of medical services in the last 20 years have significantly reduced infant and childhood mortality in Thailand. Therefore, many rare and previously unidentified genetic disorders, which, in the past, usually led to the death of affected infants before a definitive diagnosis, have now been increasingly recognized. Recently, we identified three unrelated patients from Thailand who suffered from citrullinemia, one of five inherited types of urea cycle disorders. All were diagnosed within their first few weeks of life. Biochemical analyses, including plasma amino acid and urine organic acid profiles, are consistent with argininosuccinate synthetase (ASS) deficiency. Extensive mutation study by direct genomic sequencing of ASS demonstrated a homozygous G117S mutation in one patient and homozygous R363W mutations in the other two families. 相似文献

Identification of Hb Lepore-Washington-Boston in association with Hb E [beta 26(B8)Glu----Lys] in a Thai female 总被引:3,自引:0,他引:3
The proposita was a Thai female showing signs of a mild anemia (Hb: 11.4 g/dl; RBC: 4.91 X 10(6)/mm3; reticulocytes: 2.4%; MCV: 70 fl; MCHC: 23.3 g/dl). Hemoglobins were isolated by DEAE-cellulose chromatography in the following relative amounts: Hb E + Hb A2 = 53%; Hb F0 = 30.0%; Hb delta beta-Lepore = 12.7%; Hb F1 = 4.3%. The beta E and delta beta-Lepore chains were isolated by CM-cellulose chromatography and were subjected to tryptic peptide mapping on paper in comparison to normal beta A chains. Amino acid analysis of selected peptides permitted unambiguous identification of the abnormal hemoglobins as Hb E [beta 26(B8)Glu----Lys] and Hb Lepore-Washington-Boston, which has a delta chain sequence for residues 1-87, and a beta chain sequence for residues 116-146. The presence of a Lepore hemoglobin was further confirmed by Pst I digestion of the proposita's DNA. The association of the two hemoglobin variants gave rise to elevated levels of Hb F. 相似文献
