Its antiserum was prepared by using rabbit, the end the dilution point ( titer ) of antiserum was 1/ 512. The efficiency of antiserum was tested by agglutination, and agar double diffusion tests .

The ability of three types of transport media (Tris-HCl— EDTA fluid , Normal saline and Reduced transport media) to transfer oral treponema samples was investigated , in addition to the capability of relying five types of nutritional media (New oral spirochetes, Supplumented pleupneumolike organism, Thioglycolate medium, Pepton- yeast extract- glucose, and Trypton- yeast extract- glucose- volatile fatty acid-serum medium) and two types of solidified culture media (Thioglycolate-BHI agar and Trypton- yeast extract- glucose- volatile fatty acid-serum agar) for the primary isolation and subculturing of these organisms reaching the most necessary supplements required to support the growth of these organisms. The efficacy of the three types of transport media in transport and maintenance of the vaibilty of these organisms was shown, also the efficacy of primary isolation and subculturing media to support the organisms' growth was proved after supplementing these media with the necessary growth elements. Hence it was possible to provide the optimal anaerobic conditions for the growth by the addition of reducing agents (Sodium thioglycolate and L-cystein) to the culture media and incubation in anaerobic jar, furthermore, introducing the necessary elements of long chain fatty acid by the addition of isobutyric acid and serum, and we confirm the ability of three types of serum (Rabbit serum, Fetal calf serum and Fetal bovin serum) to support the culture media. We had showing possibility of depending upon the selection isolation method by the addition the antibiotic rifampicin. Moreover, it was observed two forms of growth of these organisms: the turbidity after two days of inocubation and the sediment form with the shot silk after four days of incubation, and the variation in colonies form on the solid media was also clear.

The role of some growth regulators in the initiation and callus growth from seedling's stem explants of tamarind (Tamarindus indica L.) was carried out.Benzyladenine (BA) was used at concentrations (0.0, 0.5, 1.0, 1.5, 2.0) mg/l, while Naphthaleneacetic acid (NAA), Dichlorophenoxyacetic acid (2,4-D) and Indolebutyric acid (IBA) for each were used at various concentrations (0.0, 0.5, 1.0, 1.5, 2.0) mg/l.
The result indicated that the best medium for growth callus was the MS medium containing 1.0 mg/l BA, depending on callus fresh weight after 90days of growth. The addition of 3% of sucrose to MS medium stimulated the initiation of callus well.
Moreover, shoot development occurred on callus grown on medium containing BA (1.5mg/l) after 70 days of growth. The differentiated callus was subcultured on hormone-free medium and then the plants developed can be readily transferred to the soil after harding

This paper describes the development of a spectrophotometric method for the determination of chlorpromazine hydrochloride drug via oxidation reduction method which based on the reduction of iron (III) by the chlorpromazine hydrochloride to iron(II) which gives a soluble colored complex when reacts with the reagent 2,2`-bipyridyl at room temperature having maximum absorption at 521 nm against reagent blank. Beer´s law was obeyed over the concentration range of 2.5 to 300 µg/25 ml with an apparent molar absorptivity of 1.054 x 104 l.mol-1cm-1 and Sandell`s sensitivity of 0.033 µg.cm-2. The relative error is ranged from -0.1 to -1.66% and relative standard deviation from ±0.2 to ±1.37% . The method has been applied successfully to the determination of chlorpromazine hydrochloride in two dosage forms : tablets and ampoules. Additives and excipients normally found in dosage forms do not interfere
