trial to estimate unknown person's height by the vertical distance of located earprint in case of bending over in an extreme curve

This study is a trial to create a formula solving the problem of estimation ofperson's height from a located ear print, which was printed while bending overin an extreme curve. This work was performed on 100 volunteers of differentages and both sexes. They were classified into two groups, each of 50volunteers. The first group was the measurements group, each volunteer ofthis group was measured for some distances, then printed his ear four times infour different positions, then the angles of the line of the anterior bordersof these prints were measured. The second group was the application group,each volunteer of this group printed his ear only one print during listening,while bending over in an extreme curve, then the angle between the line ofanterior border of his ear print and the horizontal line was measured, thenhis height was estimated using the proposed formula. The calculated heightswere compared with the actual heights of volunteers

study of lip prints data

This work was performed on 480 lip prints from 60 different lips of 30volunteers. These lip prints were divided into four groups: In groups I andII, the prints were recorded by using slight and moderate pressure of thelips, respectively, and in groups III and IV, the prints were recorded afterone month from recording groups I and II also by using slight and moderatepressure of the lips, respectively. After examining the lip prints andcomparing them with each other, the study concluded that slight pressureof the lip during recording is the best method for obtaining a lip printrecord used for comparison. Lip prints did not change after one month. The proposed method of lip prints identification depends on threefactors [primary lines, secondary lines and the distance between two knownfixed patients]

Effects of lead toxicity on some important immune factors in human and experimental animals

Lead [pb] is the most common environmental and workplace contaminantpresenting health problem following exposure. This study aimed to investigatethe effect of lead on serum immunoglobulins [IgG and IgM] in exposed workersafter detecting its level in their blood and detect IgG and IgM in serumof albino rats after exposure with detecting IgE that bind to specificcell surface receptors on tissue mast cells. Serum IgG and IgM levels wereestimated by an enzyme- linked immunosorbent assay [ELISA]. Rats weresacrificed to study mast cell degranulation. The results showed a significantdecrease in IgG and IgM level together with an increase degranulation of mast.cells

Effect of somkoing on plasminogen

The present work was performed on 80 male volunteers classified into 3 groups; the control [non-smokers] group, the ex-smokers group and the smokers group. The last group was subdivided into 6 subgroups according to age of startsmoking, number of smoked cigarettes/day and duration of smoking. A bloodsample was obtained from each volunteer and examined for plasminogen level. It was found that the most important factor affecting plasminogen level is theage of start smoking and that cessation of smoking returns plasminogen to itsnormal level
