In general the success of biosystem depends on its flora . Human represents superorganism as it contains variable microbial flora which called human microbiome. The latter divided into core microbiome and variable microbiome . Distribution of human microbiome concentrated in systems and organs exposed to the outer environments, such as ; skin, mouth , nose, digestive channel , urogenital channel .Vagina represents one of the secondary environment in the body responsible for reproductive health . and since it exposes to the external environment it should have some sorts of defenses . The components of vaginal defenses are: vaginal epithelial cells and its associates which excretes some defensins. Vagina has its own innate immunity, presence of IgG, IgA. In the vagina, there is some enzymes or enzyme inhibitors such as Stable serine protease inhibitor (SLPI) . In addition there are some more defense facilities such as Mannose binding lectins (MBL) , Chaperone (HSPs) which increased upon infections and inflammations , antimicrobial peptides. The main natural flora of the vagina is Lactobacilli, which classified into Lactobacillus acidophilus complex using routine rout and can be differentiated more using molecular route . These bacteria are responsible for setting the acidic reaction of the vagina . It can protects vagina against different infections and can be used to restore the unbalanced vaginal conditions if it selected carefully according to certain criteria .

Olive oil extract was studied for diabetes mellitus that induced by alloxan in mice to development herbal medicine against the non communicable disease. We have measured the fasting blood glucose level (serum). Hyperglycemia and hyperlipidemia are two important characters of diabetes mellitus. Hyperlipidemia developed in these experimental diabetic mice was assessed by quantification of total cholesterol (TC), high-density lipoprotein cholesterol (HDLc), and triglyceride (TG) in serum, so the extract of olive oil have some remedial effects against alloxan-induced diabetic mice. Forty five adult male mice used in this study, animals were divided into three equal groups :Control without any treatment (A), alloxan treated (B) and group(C) induced diabetic and treated with the extract of olive oil (0.5ml/100g B.W). All animals were sacrificed 2,4,6 weeks post treatment respectively. After treatment of extract of olive oil in alloxan-induced diabetic mice the result showed a significant remedial effect on blood glucose level, None of the extract has any metabolic toxicity induction in general (by measuring level of GPT, GOT and ALP).

In this study, two polymerase chain reaction (PCR) assays were performed individually for the molecular detection of Pseudomonas aeruginosa obtained from wound and burn samples. Two gene were targeted as specific markers for P. aeruginosa namely the exotoxin A (exoA) gene and the outer membrane lipoprotein (oprI) gene. Seven isolates for each of P. aeruginosa and other Pseudomonas species were employed in this study and boiled bacterial suspension was used as a DNA template. Results showed that all P. aeruginosa isolates gave positive PCR product for oprI gene with amplified size (196 bp) while only 4isolates were harboring exo A gene with amplified size (396 bp). Results for PCR product for Pseudomonas sp. Revealed that none of the seven isolates were positive for exo A gene and only 4 were positive for opr I gene. This research may indicates that molecular detection of P. aeruginosa from wound and burn samples employing exo A and opr I genes by using PCR technique is a rapid method.

This study was designed to investigate the effect of different concentrations of Camellia sinensis methanol extract on the growth of human lymphocytes in vitro. The lymphocytes were isolated from healthy person free of any infection and unhealthy persons suffering from leukemia. The results showed that the extract of C. sinensis has no inhibitory effect on the growth of lymphocytes of the healthy person, or at least maintain their growth. At the same time, this extract has a distinct inhibitory effect on the total count of lymphocytes of leukemic origin when compared with the control that represents untreated human lymphocytes. It was concluded that the extracts of C. sinensis may play a role in maintenance the normal lymphocyte growth and possess inhibitory effect on the growth of human leukemic lymphocytes.

We found that the specification of raw water for Tigris river in Baghdad city ( approximately from the midpoint of water stream in the city ) was a good and need no effective treatments because the main pollutants are the turbidity and Total Suspended Solids (TSS) which represent the major pollutants only. These could be treated efficiently through the use of the new chemical treatment other than the alum and producing a large quantity of drinking water with high quality. The work included the collection and analysis of raw water samples from Tigris river during the first six months of 2011 at Alwahda project laboratories and our laboratories in university of technology . analysis results for raw water during this period showed that a number of determinants were within the acceptable range of the Iraqi drinking water specification ( especially the Total Hardness TH , 260 – 500 mg / l ; Alkalinity , 150 – 170 mg / l as CaCO3 and Total Dissolved Solids TDS , less than 800 mg / l) . The Turbidity and Total Suspended Solids ( TSS ) were not within acceptable values of Iraqi specification for drinking water and ranged between 14 -180 NTU and 27 – 362 mg / l respectively . We have used in our study a group of coagulant agents and flocculents like ferric chloride , wood ash and also the new manufactured organic compounds named ( XX-1 and poly XX-1 ) which have a good affinity to the heavy metals . The results showed that treatment the alum with ferric chloride at concentrations of 8 mg / l and 4 mg / l respectively and treatment with ferric chloride in concentration 8 mg /l were the best in decreasing the turbidity and TSS .The treatment with ferric chloride and the mixture of XX-1 and Ash gave negative results .The results showed the ability of synthetic organic XX-1 to remove the heavy metals from raw water , but have less ability to reduce the turbidity and TSS . It also observed the effect of ash in decreasing the turbidity and suspended solids when used with a alum .The clearness time was reduced to less than one hour after treatment with ferric chloride compared with alum (that use in Alwahda project ) . The results showed high efficiency for ferric chloride in reducing microbial contaminants especially the Total Viable Count (TVC) and coliform viable count . The effect of ferric chloride was started from 10 mg / l compared with the alum treatment . Microbial contamination decreased about 4 log by using 20 mg / l of ferric chloride to become 102 cell / 100 ml compared with the alum treatment (106 cell / 100 ml )

The aim of the present study was assess the cytotoxic activity of seed oil on two cell lines (RD and L20B), through different exposure time (24 , 48 and 72 hrs.) and different concentration of seed oil (1.3 , 2.6 , 5.2 , 10.4 , 20.8 , 41.6 , 83.2 and 166.4 µg / ml) in vitro. The results showed that rapeseed ( Brassica napus L.) seeds oil has toxic effect on RD cancer cell line at high concentrations (83.2 and 166.4 µg/ ml) during 48 and 72 hrs. in comparison with the control. On the other side the result showed that there is no significant effect of these seed oil on the L20B transformed cells, except the treatment with higher concentration (166.4µg/ml) after 48 hrs. exposure time. In conclusion, the oil was shows selective (cell line – dependant) inhibitory effect on cancer cell lines and the plant may be a promising anticancer drug. Other biological properties should be appeared through the use of this oil extracted from the seeds of rapeseed.
