In addition, the introduction of the effect of mode locking process using frequency modulation in order to get a stream ultrashort pulses. Selecting an suitable frequency modulated pulses achieved the stream could reach the stage of stability according to a certain number of trips round-trip (RT), since the highest frequency accompanied by a number less than the RT. On the other hand, the increase in R adversely affect the output pulses stream. The interval time between resulted pulses is inversely proportional to frequency modulated. stream pulses can be stable in the energy and pulse width with RT appropriate. increase factor 2  contribute to stability of pulses energy while 3  did not show any effects. The effect of the pumping energy represent of the 0 g worker showed that resulting energy increases with increases this factor.

Paracetamol (PCM) overdose can cause hepatotoxicity with oxidative stress as one of the possible mechanisms mediating the event. In present study, the effects of Fluvastatin(10mg/kg) and (20mg/kg) on PCM-induced hepatotoxicity were examined. Rats were divided randomly into five groups containing 9 rats each. The control group received normal saline (the vehicle). Other groups were treated with Fluvastain alone (20mg/kg), PCM alone (600mg/kg), (600mg/kg PCM + 10mg/kg Fluvastatin), and (20mg/kg PCM + 20mg/kg Fluvastatin) respectively, for 4 weeks. Paracetamol induced male rat hepatotoxicity represented by significant decline in the serum total albumin (P< 0.05). However, the study appeared significantly increment (P< 0.0001), bilirubin, ALT, AST and ALP as shown in group2 (induction group) in comparison with group1 (control group). However, simultaneous administration of fluvastatin (10mg/kg and 20mg/kg) with paracetamol, significantely was attenuated the adverse changes in the serum total albumin, bilirubin, ALT IU/L, AST, and ALP. \u0000On the other hand, the biochemical observations were supported by histopathological examination of liver sections.

Abnormal release of DA will contribute to some diseases such as Alzheimer’s and Parkinson's disease. Therefore, the sensitive determination of DA becomes increasingly significant in the field of clinical disease diagnosis and the research of physiological functions. Progesterone is an essential for the development and cyclical regulation of hormone responsive tissues including the breast and reproductive tract. In the breast, progesterone acts in concert with estrogen to promote proliferative and pro-survival gene programs. Progesterone has actions in breast cancer. This paper shows a spectrophotometric method for determination dopamine and progesterone concentration in serum samples, fifty six veins blood samples collected from healthy control and breast cancer patient groups. The analytical data obtained by using UV-Spectrophotometer (  max = 250, 266 nm), linearity (0.5 - 2.0, 0.25 - 1.5 ng/ml) for dopamine, progesterone respectively.
