blood samples (291857) from 24 provinces of iran were tested for abo and rh groups. the rh complexes as well as kell, duffy, kidd, lutheran, kp and xg blood groups were tested only on a part of the material from tehran. results show a great deal of heterogeneity for abo and rh groups in various provinces of iran. the calculated gene frequencies are compared with those of other investigations in...

background: the goal of the present work was to determine frequencies of different finger patterns of a population in hamadan (one of the western cities of iran) in 1997. methods: in a cross-sectional study, the .prints of the first phalanx of both hands of 717 randomly selected hamadan students (i88 men, 529 women) have taken, by using standard method (stamp ink). the fingerprints were classif...

the photoanthropometric method was used to study the facial features in 136 iranian children with down syndrome, aged 4 to 14 years. nineteen parameters were investigated and compared to an age related control group of 100 normal iranian children. the obtained measurements were related to reference values in the same faces. the normal range was defined by age related index values between the 20...

angiotensin converting enzyme (ace; omim: 106180) has an important role in the conversion of angiotensin i to angiotensin ii and degradation of bradykinin. genetic polymorphism i/d (rs4646994) in the gene encoding ace has been well defined. to get more insight into the genetic structure of iranian populations, the distribution of the ace i/d polymorphism among iranians was compared with each ot...

background: previous studies have revealed significant differences between populations for genotypic frequencies of glutathione s-transferase t1 ( gstt1 ) and m1 ( gstm1 ) polymorphisms. in order to find the frequency of the null genotypes of gstm1 and gstt1 in iranian populations, the present study was carried out. methods: the total study subjects consisted of 1340 unrelated healthy muslims/i...

background: essential hypertension tends to a familial mode. its pattern of inheritance is heterogeneous, but the frequencies of different mode of inheritance vary in different populations. determining of the mode of inheritance in each family is the basic information that is needed for the risk estimation in those family members. determination of pattern of inheritance in families with at leas...

background: the variable numbers of tandem-repeat (vntr) alleles at the phenylalanine hydroxylase (pah) gene have been used in carrier detection and prenatal diagnosis in phenylketonuria families. this study was carried out to analyze vntr alleles at the pah gene in iranian azeri turkish population. methods: in this study, 200 alleles from general population were studied by pcr. results: the fr...

common kilka clupeonella cultriventris (nordmann, 1840) is a brackish water and small pelagic fish species and is one of the most abundant fishes that live gregariously in the caspian sea. a total of 60 specimens of adult common kilka were sampled from two seasons. fifteen pairs of microsatellites previously developed for a.sapidissima, c. pallasi, c.harengus, and s. pilchardus were tested for ...
