Ø  Effect of Some Bio-Regulators on Growth and Yield of Some Wheat Varieties under Newly Cultivated Land Conditions.


Ali A El-Hosary, Gaber Y Hammam, Abdalla El-Morsi, Esmat A Hassan, Mohamed E El-Awadi, Yasser R Abdel-Baky


This investigation was conducted to study the effect of some bio-regulators, tryptophan, cysteine, thiamine, ascorbic acid and yeast extract on growth, yield and its components and some chemical constituents of some wheat varieties; Sakha93, Gemiza7 and Gemiza9 under newly cultivated land conditions. For this purpose two field experiments were carried out during two successive growing seasons (2008\2009 and 2009\2010) at the experimental farm of National Research Center at Nubaria, Egypt. Results revealed that foliar application of different applied growth bio-regulating substances, with different concentrations, significantly increased all growth criteria, plant height, number of tillers and leaves per plant, fresh and dry weight of plant. Grain and straw yield of wheat plants and yield components were also significantly increased as result of foliar application of the used bioregulators. On the other hand Gemiza-7 variety was most effective of all characters under study compared with the other two varieties Gemiza-9 and Sakha-93.


Ø  A Comparison of the Pre-Competition and Post-Competition Anxiety Levels of Taekwondo Athletes.


Behrouz Ghorbanzadeh, Perican Bayar


A total of 468 taekwondo athletes, 231 females and 237 males, in the adult category, who had participated in the 2012 Turkish Taekwondo Championship; with an average age of 20.91 years (Sd=3.66) participated in the present research for the comparison of the pre-competition and post-competition anxiety levels of taekwondo athletes. The research was conducted using the survey technique of data collection and the competitive state anxiety inventory-2 (CSAI-2) (Martens, Burton, Vealey, Bump and Smith 1982) and it was used in the present research to measure the anxiety levels of the sportspeople. The Turkish implementation of the inventory was performed by Koruç (1998). Statistically significant difference cannot be found between the inventory scores of females and males who participated in the research according to their genders (P>0.05). Whether there was a significant difference between the inventory scores of sportspeople according to their ages was tested by one-way analysis of variance, and a statistically significant difference was found between the self-assessment scores of the taekwondo athletes measured 1 day before according to their ages (P<0.05). A significant difference was not found between the selfassessment scores of athletes measured 1 day before according to their sports ages (p>0.05). Consequently, it was observed that the cognitive and somatic anxiety scores of taekwondo athletes increased and their self-confidence scores decreased as the competition drew closer. After the competition, it was detected that the cognitive and somatic anxiety scores decreased and self-confidence scores increased. The anxiety levels of the taekwondo athletes increased just before the competition, but a decrease in anxiety was observed after the competition. Pre-competition and post-competition anxiety levels were found to have an effect on the success of the athletes. All in all, it was observed that the state anxiety measured by CSAI-2 showed pre-competition and post-competition changes and there was a change in anxiety cognition.


Ø  Nutraceuticals from Bitter Leaf (Vernonia amygdalina Del.) Protects against Cadmium Chloride Induced Hypertension in Albino Rats.


Olaiya CO, Choudhary MI, Ogunyemi OM, Nwauzoma AB


In recent years, the consumption of nutraceuticals, natural plant foods, and the use of nutritional therapy and phytotherapy have become progressively popular to improve health, and to prevent and treat diseases. This study investigated the cardioprotective and hepatoprotective effects of some nutraceuticals from Vernonia amygdalina namely, β-sitosterol (BSS), β-sitosterol glucoside (BSSG) and BSS: BSSG mixture on certain parameters in hypertensive wistar albino rats. Hypertension was induced with Cadmium Chloride and the biochemical analyses of serum were carried out following treatment with BSS, BSSG, BSS:BSSG mixture and lisinopril. Serum urea, creatinine, calcium and electrolytes levels were assayed using appropriate standard methods as tests for renal function, while alkaline phosphatase (ALP), aspartate transaminase (AST) and alanine aminotransferase (ALT) served as enzyme indices of the liver function. The effect on the serum lipid profile was also assessed. Data collected were expressed as mean ± SEM and analysed using one-way ANOVA. The sodium levels had a significant (p<0.05) reduction in BSS and BSS:BSSG mixture treated rats. BSS treatment also gave a significant (p<0.05) decrease in triglyceride and total cholesterol levels while BSSG treatment gave 60.4% increase in HDL-Cholesterol levels and increased HDL-Cholesterol: LDL-Cholesterol ratio. Generally, treatments with the phytosterols reduced the levels of serum AST, ALT, ALP and tends to maintain urea and creatinine basal levels while lisinopril significantly increased (p<0.05) serum urea and creatinine levels. Tissue sections from phytosteroltreated groups show no visible lesion as against those from hypertensive rats that show areas of extensive necrosis. This study revealed that these nutraceuticals possess cardioprotective and hepatoprotective properties, with possible practical application in the management of cardiovascular diseases (CVDs).


Ø  Can Ultrasound Be an Effective Imaging Tool in Life Threatening Complications of Pregnancy?.


Gihan Hassan Gamal, Lamyaa M Yosry


Acute life threatening complications can arise during pregnancy and early postpartum period and result in maternal and fetal morbidity and mortality. Common clinical signs are vaginal bleeding and pelvic or abdominal pain. The aim of this work was to improve the role of Ultrasound in identifying the causes, differential diagnosis and management of major acute life threatening complications of pregnancy Sixty eight pregnant women complaining of vaginal bleeding with pelvic or abdominal pain were followed up in the US out patients, US emergency unit at 6th October hospital over a period of one year. Ten cases were in the postpartum period and the remaining cases were at different ages of gestation. They were examined by trans abdominal, using 3.5 MHz sector probe or transvaginal technique according to the suspected clinical examination. Our results could depict, according to US findings, five groups of pregnant complications: ectopic pregnancy, placenta previa, placenta morbid adhesion, placenta abruption and retained product of conception. Conclusion  It was proved that US is an important and helpful tool in investigation and diagnosis of threatening life complications of pregnancy, but should not override the clinical obstetric judgment.

Ø Antioxidant and Trace Metals Levels in Anemia


Saira Baloch, Naila Masood, Imran Ali Shaikh, Ali Raza Memon


Anemia is a disorder characterized by reduction in hemoglobin concentration of blood below the normal level. It is a global problem, mainly affecting poor people in developing countries. For the determination of these metals fifty intravenous blood samples anemic patients and normal subjects were collected and immediately centrifuged to obtain the supernatant liquid, serum of both the groups for analysis. The mean serum levels of magnesium, zinc, copper, and iron and antioxidant activity in anemic patients were 16.05±1.14ppm, 4.33±0.28 ppm, 2.5±0.2ppm, 1.50±0.28ppm and 1.27±0.05ppm respectively. Serum magnesium, zinc, iron and antioxidant levels were significantly lower whereas, the higher level of Copper was observed in anemic patients as compared to the controls. Supplementation with deficient trace elements may reduce the severity of symptoms and complications associated with anemia.
