Background: Tympanometry findings are considered by many investigators to be associated with passive and active smoking.
Patients and methods: One hundred forty healthy adult men aged (20-50 years). 70 smokers and 70 nonsmokers were recruited for the study. The examination included otoscopy, and screening tympanometry. Smoking history was ascertained by self –report. For each subject, age, smoking status and number of cigarettes per day were noted.
Results: There is a tendency for more negative middle ear pressure in smokers than in non-smokers though this difference may not clinically significant. There were no significant differences in ear canal volume, middle ear compliance and presence of Staped

Experiments were conducted to study axial liquid dispersion coefficient in slurry bubble column of 0.15 m inside diameter and 1.6 m height using perforated plate gas distributor of 54 holes of a size equal to 1 mm diameter and with a 0.24 free area of holes to the cross sectional area of the column. The three phase system consists of air, water and PVC used as the solid phase. The effect of solid loading (0, 30 and 60 kg/m³) and solid diameter (0.7, 1.5 and 3 mm) on the axial liquid dispersion coefficient at different axial location (25, 50 and 75 cm) and superficial gas velocity covered homogeneous-heterogeneous flow regime (1-10 cm/s) were studied in the present work. The results show that the axial liquid dispersion coeffic

ackground :Polyphenolic compounds are groups of naturally occurring compounds in different plants. They are promising product to protect, and prevent leukemia and many types of cancer by different mechanisms.
Objectives: The present study designed to study the effect of polyphenolic compounds [Ellagic acid (EA), Tannic acid (TA) and Caffiec acid (CA)] on GOT,GPT activities and total protein TP concentration in all types of leukemia [acute myeloblastic leukemia (AML), acute lymphoblastic leukemia (ALL), chronic myeloblasti leukemia (CML) and chronic lymphoblastic leukemia (CLL)],in addition to compare the potency of these compounds among each other.
Patients and Methods: Blood samples were collected from a h

    The aim of the current study is to demonstrate the effect of honey on the sperms characteristics (sperm concentration, sperm motility, grade of activity and sperm normal morphology) as well as pregnancy rate in mice. Sperms were obtained from caudal epididymis of male mice and prepared by adding10% of honey to the IVF medium using direct sperms activation technique for 30 minute incubation period before artificial insemination.

    The study revealed a significant (P > 0.05) increase in active sperm motility (grade A and grade B) 49% and pregnancy rate 53.3% in female mice artificially inseminated with sperms. On the other hand, there were no significant differences in sperm con

Smoking is the most noticeably horrible human conduct; it is rehearsed by individuals dependent on nicotine numerous hurtful sicknesses, for example, cancer and liver disorder are brought about by smoking cigarettes. So this study aimed to study some of the liver function represented by the enzymes aspartate aminotransferase (AST or GOT) and alanine aminotransferase (ALT or GPT) in smokers and non-smokers for 50 persons in a group consists of 25 smokers and 25 non-smokers of different ages and to study the effectiveness of cigarette smoking on liver enzymes by checking the secretion of (AST) (35.84± 4.1)U/ 1 (ALT)(51.08±7.286 ) U/1(p<0.05) relative to non-smokers were significantly correlated with heavy cigarette smoking.

Cyanobacteria are prokaryotic photosynthetic communities which are used in biofertilization of many plants especially rice plant. Cyanobacteria play a vital role to increase the plant's ability for salinity tolerance. Salinity is a worldwide problem which affects the growth and productivity of crops. In this work three cyanobacteria strains (Nostoc calcicola, Anabaena variabilis, and Nostoc linkia) were isolated from saline soil at Kafr El-Sheikh Governorate; North Egypt. The propagated cyanobacteria strains were used to withstand salinity of the soil and increase rice plant growth (Giza 178). The length of roots and shoot seedlings was measured for seven and forty days of cultivation, respectively. The results of this investigation showed

Background: Knowledge about the clinical problems during the fast of Ramadan is important in order to opens the way to further research aimed at discovering the significance of Ramadan fasting in patients with heart disease.
Patients and Methods: Eighty-six outpatients with heart disease with intention to fast were studied in the month of Ramadan 2010 (1430 H) at the Ibn Al-bitar Hospital. Detailed clinical and biochemical assessments were performed within 3 days before the start of Ramadan and then on the last day of Ramadan.
Results: There were 54 (62.8%) males and 32 (37.2%) females with a mean age of 56.3 years (range, 17-84 ). Forty-six patients (53%) had coronary artery disease, 23 patients (27%)

Atenolol is one of beta-adrenergic receptor blocking agent. It is widely used for the treatment of hypertension as a selective antihypertensive drug. But long term usage of atenolol may cause one of the cardiovascular diseases like myocardial infarction. To prove the relationship between atenolol and cardiovascular disease, measurement of creatinekinase-MB as a diagnostic indicator in early and long term usage of this drug by hypertensive patients is recommended.  A comparative study was conducted in Al-Yarmouk Teaching Hospital–Emergency Department- on 30 hypertensive patients using atenolol. They were divided into (2) groups A and B according to the duration of the drug usage. Group A- (15) patients with a mean age (56

    The aim of the research was to assess effects of short and long-period exposure to radiation from mobile phone on blood indices in experimental rats. In this study forty mature female rats were used; the animals were divided into two experimental group, each group consists of twenty animals. Short-period group of rats were exposed to cell phone radiation for different duration 30 m, 60 m, and 90 m per day for six weeks. Long-period group of rats were exposed to radiation from mobile phone for different duration 2h, 4h, and 6h per day for three months. The study noticed that there was significant (P≥0.05) elevation in total white blood cells and the study demonstrated significant increment (P≥0.05) in percentage of

Background:The initiation and maintenance of reproductive functions are related to an optimal body weight in women. Body weight affectthe ovarian reserve which is basically an estimate of how many oocytes (eggs) are left in the ovaries.
Objective: To study the relationship between obesity and serum and ultrasound markers of ovarian reserve in mid-reproductive age women (21- 35 years old).
Patients and method:Twenty participants (“obese”) had a body mass index (BMI) of 30 to 35 Kg/m2 and another 20 participants (“non-obese”) had a BMI20-29 kg/m2. The obese women had a mean age of 27.9 years and the non-obese women had a mean age of29.5 years. Blood samples were collected from all participants, a
