Abstract: We studied 119 members of 22 asthmatic multiplex
families. Incuded were 44 parents ( seven were asthmatics),
48 sthmatics (23 were undergoing an attack at the time
of sampling and 27 normal siblings. The following investigations were carried out on all subjects :1)
detection of total T lymphocytes, helper cells, and
suppressor cells, using monoclonal antibodies (OKt3,
OKT4 and OkT8), 2)study of nonspecific T-lymphocyte
blast transformation induced by PHA, and 3) HLA-A,B
and DR antigen determination using the microcytotoxicity technique. The results were compared with normal ranges
and data for normal group and statistically and genetically annalyzed. They indicat : 1)The number of T-cells was low
in asymptomatic asthmatics and normal in asthmatics in
attack; 2) There were fewer helper and normal suppressor
cells (that is , a low H:S ratio )in asymptomatic asthmatics ,
and a normal amount of helper and suooressor cells ( a normal H:S ratio ) in those experienccing an attack; 3)
there was a percentage of a lymphocyte transformation in
both groups of asthmatics; 4)whereas the T-helper cells
pressor cells during an attack, which points to deficient
function of suppressor cells; 5) the disorder is inherted
and the gene controlling this fysfunction is HLA-linked
and probably dominate.

Summery :Previous work on the inheritance of disease has often
used certain measures of HLA haplotype concordance ( such as the
number of haplotypes " identical by descent," IBD ) among affected
siblings from each of a number sibships, each of which contains
at least two affected siblings. Here we interduce a a new measure of
measure of HLAhaplotypes discordance betwen the affected and
unafected siblings of each sibship ( provided that there is at least one
at each). we show how the measure can be used to give a simple
test for inheritance which we examplify with data.

An exact test for HNBUE CLASS OF LIFE DISTRIBUTIONS. Journal Of Statistics AndComputional Simulation.Vol.60, pp.261-275.(1995). (UK)
This paper introduces an exact test for testing : F is exponential against is harmonic new better than used in expectation ( HNBUE ) or F is harmonic new worse than used in expectation ( HNWUE ) on complete data.Selected critical values are tabulated for size n =5(1)60. An asymptotic test is made available for large values of n. The standard normal table can be used for the above testing problem. Power of the test is estimated by simulation. The problem when right censored data is available is also handled. An example of 81 patients of melanoma disease demonstrated the practical application of the proposed test in medical Scences.

Better Than Used In Expectation Class Of Life Distribution
Based on the Total Time on Test Transform . Journal Of The Egyptian Statistical Society.Vol.17, No.1 , pp.28-38.(2001).
Let F be a life distribution with survival function and finite mean
The scaled total time on test transform is defined by and the properties of for harmonic new renewal (worse) than used in expectation are investigated. Test statistics for testing exponentiality against harmonic
new new renewal better (worse) than used in expectation are proposed. The percentiles of these test statistics are tabulated for small samples
sizes. These tables can be used by reliability engineers to chick whether
a set of life data has the harmonic new renewal better than used property
or its dual. Powers of the tests are estimated by simulation. A set of real
data are used as an example to elucidate the use of the proposed test statistics for practical reliability analysis.
