Abstract

This study was aimed to micropropagate Lisianthus Eustoma grandiflora plant which is one of the important cut flowers. The study included many experiments, at the initiation stage, the effect of the two auxins Indole butyric acid (IBA) and Naphthalene acetic acid (NAA) supplemented to Murashige and Skoog medium (MS) containing 0.3 mg/l of Benzyladenine (BA) were investigated for their effect on mean number of initiated shoots and length. type of explant were used namely, leaf discs. The effect of different strengths of MS and B5 media on mean number of multiplied shoots was also studied. During acclimatization, different mixture ratios of peat moss and river sand were examined in their effect on plantlets survival. Results showed that IBA achieved the highest mean shoot number formed on the three explants types under investigation reached 6.8 shoots with a mean length of 2.75 cm. Maximum mean shoot number reached 7.3 at the concentration 0.1 mg/l of IBA while maximum mean shoot number reached 6.4 at the concentration 0.0 mg/l of NAA. Results also revealed that MS medium was better than B5 medium in sustaining shoots yielding 8.8 and 6.6 for both media respectively. A significant reduction in mean number of shoots occurred with reducing the medium salt strength. Shoots transferred to MS medium supplemented with 1.0 mg/l of IBA produced the highest mean root number, length and rooting percentage reached 5.5 roots, 2.5 cm and 70% respectively while rooting percentage did not exceed 20% when the same medium was supplemented with 1.0 mg/l of NAA. Plantlets were successfully acclimatized achiving 90% survival when grown on agricultural medium consisted of river sand : peat moss (2:1)v/v.

Abstract

This research was conducted to measure the safety of heat stable enterotoxin a (STa) produced by enterotoxigenic Escherichia coli, through studying its toxic effect on mice since it showed a promising effect in reducing the proliferation of colorectal cancer cells. The cytogenetic effect was determined after giving five different doses (100, 200, 400, 800 and 1600)µg/Kg in comparison with negative (phosphate buffer saline / PBS) and positive (mitomycin C/ MMC, at doses of 2 and 5µg/Kg) controls on mouse bone marrow cells by employing the following parameters: mitotic index, chromosomal aberrations and micronucleus, also, the serum level of liver functional enzymes (GOT, GPT, ALP) was recorded. In addition, lethal dose 50 (LD 50) with certain clinicopathological changes in five organs (colon, kidney, liver, stomach and lung) was also determined after oral administration of STa for ten successive days and at two doses (500 and 1000) µg/Kg. Results showed that, none of the five different doses of STa caused any significant changes in the three examined cytogenetic parameters in the mouse bone marrow cells; precisely, neither the low dose nor the high one of STa caused reduction or induction in these parameters. In fact, clear effect in decreasing mitotic activity and increasing spontaneous frequencies of both chromosomal aberrations and micronucleus was revealed after MMC treatment. Furthermore, significant differences in mouse serum level of the three enzymes were not seen at any doses of STa, while significant reduction in the levels of these enzymes was noticed after treatment with the two doses of MMC. In this study the LD 50 test was used to investigate the lethal effect of the partially purified STa, and it was shown to be not lethal to mice at both doses of (500 and 1000) µg/Kg, since death was not recorded, moreover, no clinicopathological effects were indicated in the all examined mouse tissues, however the only noticed clinical sign was diarrhea with all doses, which was observed after three days of STa treatment.

Abstract

The aim of this study was to evaluate the genotoxic effects of copper on Cucumis sativus L., fife levels of copper sulfate as aqueous solutions were added as a total concentrate of the soil using the concentrations (100, 200, 300, 400, 500) milligrams per one kilogram of soil, the control soil were using without additional copper sulfate. Random amplified polymorphic DNA (RAPD) technique was used for detection of genotoxic produced by this metal. Twenty one primers were used, of which three did not amplify, three gave extremely faint and ambiguous bands and the rest of fifteen primers generated single and polymorphic bands. All genomic DNA of Cucumis sativus L. exposed to copper sulfate solutions displayed polymorphic fragments which were not detectable in DNA of unexposed plants, but high concentration (500 mg/kg soil) of copper sulfate had the strongest effect on genomic DNA of Cucumis sativus L. when compared with other concentrations. Thus, this study confirmed that RAPD markers, as a fast, and simple technique can be used for detection of genotoxic effects of copper on Cucumis sativus L. plants which are growing in heavy metal polluted soils.

The effect was studied in mammalian system in mice depended on evaluating the enzymatic activity of three hepatic enzymes: Alanine Transaminase(ALT), Aspartate Transaminase (AST) and Alkaline Phosphate (ALP).Two concentrations of pure cinnamic acid (60,30) mg/body weight were tested to choose the suitable concentration which compared with negative control, positive control and comparative group of Vitamin C. In order to use in the interaction experiments, included two types of treatments pre-trichlorfon and post-trichlorfon in order to determine the mechanisms of the pure cinnamic acid, showed no toxic and hepatotoxicity influence in biological system and it showed highly performance in prevention or reduction in hepatotoxicity of trichlorfon. Cinnamic acid increased the ALT, AST and ALP enzymes with normal levels especially with dose of 30 mg/body weight. The positive effect of cinnamic acid was higher when used as post-trichlorfon treatments and to less extent in pre-trichlorfon treatments, therefore, cinnamic acid can be considered as a cure hepatocytes from acute liver damage also work protective to cardiac, skeletal muscle and placental tissue protective.

Abstract

This study was conducted to evaluate the efficiency of Benzol thaidazole-7carbothioic acid-S-methyl ester (BTH or Bion) to induce systemic resistance in tomato, Solanum lycopersicum L. to root knot nematodes, Meloidogyne spp in tomato plants 30d after treatments. Results showed that Bion was efficient in inducing systemic resistance to root knot nematodes in tomato plants. Foliage spraying or soil drenching at 50 mgL-1 were superior over the other test concentrations and seed soaking treatments. At this concentration gall index was 2.11 compared with 5 in control. Root fresh weight and root dry weigh were 6.25 and 0.62, 8.40 and 0.70g for treated and control plants respectively. Shoot fresh weight and dry weight recorded 23.60, 2.29, 17.42 and 1.42g for treated and control plants respectively. The number of second stage juveniles penetrating the roots was 51.33 and 114.88 in treated and control plants respectively. Application of Bion at this concentration also reduced gall index to 2.88 compared with 5 in control. At 50 mgL-1 of Bion root fresh and dry weight was 4.68, 0.44 and 21.40, 2.52g compared with 8.58, 0.69, and 26.21, 4.45g in control plants respectively. At this treatment also a significantly less juveniles, 75.55 entered the roots of treated plants compared with 116.66 juveniles in control.

Abstract

Pleurotus ostreatus produced 2.93 U/mg of laccase in solid state fermentation (SSF) using barley bran as substrate under optimum conditions. The optimum SSF conditions were: pH 6.5; temperature, 25Cº; inoculums size 3.5 mm and moisture content, 1:1.5 w/v. Laccase was partially purified 8.29 fold with specific activity 17.5 U/mg by ion exchange chromatography after curd enzyme concentrated by dialysis against the solid sucrose. Partially purified laccase had an optimum pH of 6.5 and was stable in the pH range from 6.5 to 7.5. The optimum temperature was 45 Cº and it displayed considerable stability within the range 15 to 45 Cº with 1h incubation as well as The ability of partial purified laccase to decolorize of textile dyes showed that the blue H3R dye was completely decolorized in all concentrations within first min while yellow FG and red 3B dyes were decolorized in different percentage.

Abstract

In vitro technique was used to propagate Narcissus tazetta L. Two approaches were used. The first explants of basal discs and scale leaves from bulbs were cultured in MS medium containing different concentrations of BA and NAA. Cultures were incubated in light and dark. Results showed that a significant increasing in shoot numbers and lengths in both types lf explants. Treatments including; light + 7.0 mg / L BA + 0.0 mg / L NAA (15.8 shoots) and light + 3.0 mg / L BA + 1.0 mg/L NAA (9.04 cm) were significant for the basal disc. while the treatments: light + 3.0 mg / L BA + 0.0 mg /L NAA (12.5 shoots ) and light + 1.0 mg / L BA + 0.0 mg / L NAA (5.02 cm) were the best for scale leaves. Callus was induced largely in explants cultured in dark and high concentrations of NAA. The second experiment: shoots from above were cultured in MS medium containing sucrose 3 or 6% with IBA 0.5, 1.0 , 1.5 mg / L for bulb lets formation. The highest numbers of bulb lets 3.2, 3.4 were observed in: 3% sucrose + 1.5 mg / L IBA and 6% sucrose + 1.0 mg / L IBA respective. On the other hand, the bulb let diameter 7.42 mm and weight 320.4 mg were observed in: 3% sucrose + 1.5 mg/ L IBA and 3% sucrose + 0.5 mg / L IBA respectively. The formed bulb lets were transferred to peat moss plus river soil media, which then successfully grown and gave vegetative shoots in the percent 98%.

Abstract

This study was carried out to assess the protective immune effect of mixed culture of Lactobacillus acidophilus and Lactobacillus gasseri in mice infected with Salmonella typhimurium. Parameters of evaluation were total and absolute count of leukocyte and phagocytosis. Fifteen albino mice divided into five groups and designated as follows: CG used as negative control, SG was infected with 0.1 ml Salmonella typhimurium 2.5×107 cfu/ml and used as a positive control, AC was treated with 0.1ml Lactobacillus acidophilus 1×109 cfu/ml and infected with Salmonella typhimurium 2.5×107 cfu/ml, GG was doused with Lactobacillus gasseri and infected with Salmonella typhimurium, AG was fed with 0.1 ml mixed culture of Lactobacillus acidophilus and Lactobacillus gasseri 1×109 cfu/ml and infected with Salmonella typhimurium 2.5×107 cfu/ml. Results indicated that mice treated with viable Lb.acidophilus and Lb.gasseri showed a significant protective immune effect compared with positive and negative control, while mice fed with mixed culture of Lb.acidophilus and Lb.gasseri exhibited less protective effect against Salmonella typhimurium compared with groups fed with monoculture of Lactobacillus.

Abstract

The breast cancer is the most common non-skin malignancy in women. Prognostic factors are important in predicting disease. Malignant tumors are composed of a small population of distinct cancer cells, termed cancer stem cells (CSCs) possess characteristics of both stem cells and cancer cells, in that they have the properties of self-renewal, asymmetric cell division, resistance to apoptosis, independent growth, tumourigenicity and metastatic potential. Objective of this studythat detect cancer stem cell of breast cancer patients by using CD44 and study the compares between patients with breast cancer and patients with benign breast lesions. This study which included 31 patients with breast cancer and 19 patients with benign breast lesions Prognostic factors were registered including: age, histopathological subtype, degree of differentiation. Results of this was Positive expression ofCD44 was observed in 16 cases, while 15cases were negative expression of CD44 out of 31samplesof breast cancer. In Benign1cases were positive expression, while 18 cases were negative expression. CD44 expression showed high significant difference between malignant breast samples and benign samples (P <0.001).
