Summary: The investigation was carried twice: 1984 and then 1988, on
asample of 36 and 38 healthy women in the area of Zagreb. Se wasdetermined
by hydride generation of flame AAS. The mean value in1984 was 58 +- 6 ug
Se/l and in 1988 was 79 +- 11 ug Se/l (P lessthan 0,01). The increase in Se
concentration may be related tothe addition to animal forage, particulary
in fattened chickens.Se has been added to poultry feed for several years
and at thesame time per capita consumption of poultry products hasincreased
steadily

Summary: Se and estradiol were determined in the blood serum of
29healthy women in order to evaluate a possible relation. Se rangedfrom 33
- 85 ug/l and estradiol 18,1 - 268,7 pg/ml. The resultsfailo to show
significant dependence of these two factors inhealthy women (P.n.s.). It is
known that in neoplastic diseasesSe is lowered and estrogen level is raised
in blood. This studyindicates that it is not the case in healthy
individuals.

Summary: In our study 41 semen donors were examined: 23
normospermatic and18 with a low sperm count (oligospermatic and
azoospertmatic).Serum Se blood level was determined by flameless ASS.
Spermiogramcriteria were in accordance with the World Health
Organization,1980. Serem Se blood levels in normospermatic men ( 71,00
+-3,69 ug Se/l) and in man with low sperm counts (57,72 +- 2,83 ugSe/l)
differed significantly (P less than 0,01).

Summary: A group of 63 healthy children, ages 8-15 yr, were
examined. Mean+- SD of the serum Se conc. was 57 +- 9 ug/l; age and
geographicarea have no effect on the Se status of children, but
thedifference between boys and girls was sifnificant ( P less than0,05). A
group of 23 men from Zagreb, ages 22-37 yr, were alsoexamined. The mean Se
conc. was 69 +- 18 ug/l, and astatistically significant difference was
found only between thegroup of adults and the group of children (P less
than 0,05).

Summary: The Se content in dark muscle and liver was determined in
chickenmeat of three big Croatian meat producers. The samples were
wetdigested (mixture of HNO3 and HClO4) and Se was analyzed byhydride
genetation of AAS with the recovery of 97,8 - 98,2%. Uponcomparison with
fluorimetric method the correlation coeficient of0,976 was obtained. Mean
+- ST of Se concentration (ng Se/g dryweight) was 1330+-20, 2000+-30 and
2090 +- 30 in liver and 560+-50, 520+-70 and 740+-50 in dark muscle.

Title: Selenium in the foodstufs of animal origin

Summary: For our study two kinds of meat were chosen: the liver
andskeletal muscle (steak) of three species of animals - poultry,pigs and
beef. Liver and muscle was taken because liver is theindicator of body Se
level and steak is nutritively higherquality meat. According to the results
poultry meat was found tobe highest in Se. Its level in the chicken liver
and dark musclemakes this foodstufs the most significant source of Se which
is aconsequence of serious and persistent addition of Se to thechicken
food.
The Se level in the liver and muscle of pigs is lower than thatin poultry.
In comparison with the same animal products of otherEuropean countries
which take care of Se distribution in food,pig s meat produced in our
country is considerably lower with Se.Because of the lowest level of Se
found in beef, our country isconsidered the poorest in Europe. It indicates
the lack ofcontrol over the level of Se in animal feed.
