There are four types of matter in the cosmos, and plasma is the most common. By heating the compressed air or inert gases to create negatively and positively charged particles known as ions, electrically neutral particles in their natural state are formed. Many scientists are currently focusing their e®orts on the development of arti¯cial plasma and the possible advantages it may have for humankind in the near future. In the literature, there is a scarcity of information regarding plasma applications. It's the goal of this page to describe particular methods for creating and using plasma, which may be used in a variety of sectors, including electrical, mechanical, chemical and medicinal ones. Creating and using plasma is possible in a variety of settings. Here are a few examples: Production of hydrogen from alcohol. Plasma technology's market value in the medical sector is increasing at a fast rate, which is reducing the discrepancy between the bene¯ts of plasma technology and the cost of the equipment necessary to create and maintain it.

Direct application of plasma is preferred in medical functions, so, direct application of cold plasma has obtained by the floating electrode dielectric barrier discharge (FE-DBD) system. The purpose of this paper to review the effect of (CAP) on the reproductive hormones (testosterone, LH, E2, progesterone, for male rats. The study appeared that no significant effect on E2 and progesterone hormone for all time of exposure, besides this significant difference in LH hormone (P<0.05) at 15 sec, (P<0.0001) at 30, 90 sec and (P<0.001) at 60 sec of exposure to plasma. Added to that significant difference (P<0.01) at 15, 30, 60 sec and no significant differences at 90 sec for testosterone hormone.

or on the organism for curative purposes. Cold plasma is both effective in disrupting a wide range
of microorganisms including multiple drug resistant ones (MDRs) and to stimulate proliferation of
mammalian cells. It has obtained by Floating Electrode Dielectric Barrier Discharge (FE-DBD)
system . The present study aimed to show the effected of cold plasma on the fertility hormones LH,
Prolactin, Estrogen, and Testosterone hormones for healthy adult female rats (Albino) / bulb c).
There are divided into many groups according to time exposure of plasma (15, 30, 60, and 90
second) and a reference group (without plasma exposure), with different time intervals after
exposure (1, 2, 3, 7, 14, 28 days). The concentration of hormones was measured using Enzyme
Linked Immunosorbent Assay (ELISA). The results showed that, the CAP effected slightly on the
Luteinizing Hormone (LH) and Estradiol Hormone (E2) the concentration levels slightly
increased and stay near to the reference value for all times. Prolactin hormone (PRL) was effected
significantly from the first day after exposure to CAP for all times, it was increased significantly
(P < 0.0001) for short time of exposure (15, 30 sec) than control group value, and it was
decreased significantly (P < 0.0001) than control value for time of exposure ( 60 , 90 sec). The
result of testosterone hormone is decreased significantly from the first day after exposure to CAP
for all time exposure (15, 30, 60, and 90 sec).

As plasma directly contact with organism, so the effect of non-thermal atmospheric pressure plasma that generated by
Floating Electrode Dielectric Barrier Discharge (FE-DBD) would influence levels of triiodothronine (T3), thyroxin (T4)
and thyroid stimulating hormone (TSH) hormones in healthy adult male rats (Albino) / bulb c), which have been divided
into groups according to time exposure of plasma (15, 30, 60, and 90 second) and control group (without plasma
exposure), with different time intervals after exposure (1, 2, 3, 7, 14, 28 days). The concentration of T3, T4 and TSH
hormones are measured by using Enzyme Linked Immunosorbent Assay (ELISA). Our observations show that T3, T4 and
TSH are affected by plasma from the first day of exposure. More specifically, group of (30 sec) shows a significant
increase in T3, T4 accompanied with a significant decrease in TSH and conserving in body weight (relative body weight
retention) compared to the control. Consistently, there was a significant increase in T4, with a significant decrease in TSH
and body weight in group of (60 sec), however, there was no significant change in the level of T3. Moreover, group (90
sec) shows a significant increase in T4 level starts from day one of exposure and reached to control value in the fourth
week, with significant decrease in TSH and body weight. Furthermore, group (15 sec) shows slight different in T3 and T4
levels compared to control, with a significant decrease in TSH that concomitant with normal increase of body weight.
This result indicates that the plasma effected is different depending on the time exposure, and the time exposure (30, 60,
and 90 sec) are effective with maintaining body weight, there is little increase compared to control group.

This study is based on optical emission spectroscopy (OES). Spectroscopic diagnostic method using the Boltzmann plot to calculate these parameters measured. Generally, the results show the value of Te ranged from 1.53 to 1.78 (eV) depending on the gas flow rates, electron density ranges from 2.63 to 3.12 Â 10 17 (cm À3). The plasma parameters such as (λ D , N D , and ω p) related to electron temperature and electron density was also measured. The plasma was produced at a different flow rate the impacts on Debye length, plasma frequency, and the number of particles on the surface of Debye, all of which rise with an increase in gas flow rate, are significantly influenced by an increase in gas flow rate on the plasma properties of the density and temperature of an electron.
