A detailed in vitro multiplication system for rapid micropropagataion of the
Hypericum perforatum L. has been developed. Shoot tips and axillary buds
excised from this plant which were collected from Tartous explants and surface
disinifected then cultured on MS (Murashige and Skoog 1962) medium.
This study ains for the ability of using granite waste emerged by sawing granite in
Syria, which is considered as a negative effect on the environment , which pollutes the air ,
people, animal and planit. The chemical composition of granite waste w
as defined and it
was clear that it is same as the chemical composition of glass . so we did this work by
transforming the waste caused by granite sawmills to the glassy state.
The preparation for the glassy states were done py two methods , the first by adding
sand and sodium carbonate and second by adding borax and sodum cab ronate and the
heattreatment was done at (900-1000 c) . The assurance of getting the glassy state through
the XRD measure to the resulted samples was done . and the chemical composition of glass
resulted by alkaline melting way was identified , then doing the chemical analyses needed
to signify the percentage of oxides of the elements and in the second step of the worke ,
they have made tests on the resulted glass (its intensity, its resistance of acids and bases ).
The decrease of intensity was noticed by the increase of silica concentration , sodium
oxide and borates oxide , and it was noticed the increase of the resistance to the acids and
alkalis by the increase of silica concentration and sodium oxide , but through adding the
borates, the result was a glass less resistant to the acids and bases .
Improving the solubility rate of fursemide in biological media by using self-emulsifying systems and preparing them in the form of tablets in order to improve its bioavailability and reduce variations in treatment between individuals. Fursemide is classified as a fourth-class drug according to the biopharmaceutical classification due to its limited solubility and permeability.
