ln this study several tests showed that high level of iron either in sera from patients with rheumatoid arthritis, th alassaemia major or in standard iron solutions, have inhibitory effect oil capsule production of cryptococcus neotormans. this work is concerned with the probable role of iron in pigeon's natural resistance against cryptococcal infection: no protease activity was detected in eit...

Richardson & Hogan (1946) produced hydrocephalus in rats by feeding a purified casein diet containing all the vitamins available at that time. Almost 2 % of the young from females fed the experimental diet were hydrocephalic; female rats fed the same diet supplemented with liver extract gave birth to normal young. It is now thought that this diet was marginally deficient in vitamin B12 (Newbern...

Two D-?-A-A sensitizers (AZ6-B20 and AZ6-B21) were synthesized by inserting the benzoxazole group as an auxiliary acceptor between ?-linker acceptor. And a D-A-?-A sensitizer (AZ6-B19) was also in our previous works insertion of donor ?-linker. The effects groups on properties at different sites dye distinguishing. Their light harvest abilities investigated UV–vis spectra both solution films. r...

Background: Opium addiction is a global problem which has implicated many societies. Opium addiction and drug abuse is related to harmful consequences which affect life style, biochemical factors, and vitamins values, and also is considered as a risk for heart diseases. Folate and B12 levels are related to homocysteine and studies about their levels in opium addicts are controversial; therefore...

we assessed a collection of 47 fluorescent pseudomonas spp., some with known biological     control activity against certain soil-borne phytopathogenic fungi such as, macrophomina phaseolina, rhizoctonia solani, phytophthora nicotianae var. parasitica, pythium sp. and  fusarium sp. in vitro and the potential to produce known secondary metabolites such as, siderophore, hcn and protease. the resu...

HLA class I antigen distribution of Sikh population from Punjab is presented. A total of 404 individual of Sikh community who were either donors for renal transplant recipients or staff in PGIMER Chandigarh were selected. HLA class I antigens (A and B) were identified using the standard National Institute of Health two stage micro lymphocytotoxicity assay. The phenotypic frequencies of HLA-A10 ...

The standard double-isotope Schilling test was used to study vitamin B12 absorption in seven patients with obstructive jaundice and 10 with T-tube bile duct drainage after cholecystectomy and bile duct exploration. In three and five of these patients respectively absorption was impaired. In the second group six patients were restudied after removal of the T tube, and in each case absorption was...
