BIOLOGIA

This paper presents a new process for rhamnolipid production from olive oil mill effluent (OOME) by a bacterial strain Pseudomonas sp. A01 isolated from olive oil mill contaminated soil. A biodisc reactor traditionally exploited for waste treatment was used for the production of rhamnolipid. The employed medium contained 10% OOME plus NaNO(3). After optimal physiological conditions were reached using batch culture techniques, they were applied for biodisc reactor. The yield and rhamnolipid production determined at 72 hours of incubation in the biodisc reactor were 0.69 x 10(-9) g/total cell and 0.115 g/L, respectively

KAFKAS UNIVERSITESI VETERINER FAKULTESI DERGISI

This study presents a method for the production of rhamnolipid, a biosurfactant, by Pseudomonas sp. Pseudomonas sp. cells that were grown in nutrient agar were inoculated into sterile liquid medium. Following an incubation period of 24 h, 2 ml of cells were inoculated into a different liquid medium and the results were obtained at the end of 26 hours incubation time. In our study, the effects of temperature, pH, and glucose concentration on rhamnolipid production were also investigated. Later, the same procedure was applied to immobilized cells that were kept away from the free microorganisms. The production of rhamnolipid by free cells was found to be much higher than that of immobilized cells. Free cells could be used for rhamnolipid production effectively

Acute effects of maternal smoking on fetal hemodynamics

Objective: To investigate acute effects of cigarette smoking on fetal hemodynamics. Method: Sixty seven women between 32nd to 40th weeks of gestation were evaluated. Maternal blood pressure and heart rate, fetal heart rate (FHR) tracing, umbilical and fetal middle cerebral arterial (MCA) color Doppler measurements were evaluated. Pre- and postsmoking results were compared with paired t-test. Results: Maternal heart rate significantly increased after smoking. Baseline FHR and FHR variability remained unchanged. The number of participants who had a reactive NST was 60 in 67 before smoking (89.5%) and decreased to 47 after smoking (70.1%) (p=0.009). There were no significant changes between maximum and minimum flow velocities, pulsatility index (PI), resistance index (RI) and systolic/diastolic flow ratio (S/D) of umbilical and middle cerebral arteries. Conclusion: The nicotine toad of a single cigarette may be inadequate to cause a detectable decrease in utero-placental blood flow; however, smoking prior to the FHR recording may alter the FHR reactivity.

Calvarial tuberculosis

We report a six-year-old boy who presented with swelling of the forehead, and had calvarial tuberculosis, a rare form of tuberculosis osteitis

THE IMPACT OF SYSTEMATIC USE OF ORAL REHYDRATION THERAPY ON OUTCOME IN ACUTE DIARRHEAL DISEASE IN CHILDREN

A review of our experience with diarrheal disease (DD) at the University of Istanbul Children's Hospital in Capa, covering the years 1987 to 1989, is presented in this paper. DD is one of the most common conditions encountered among patients presenting to the outpatient clinic (5.9% of all cases)

Group A beta hemolytic streptococcal infections and obsessive-compulsive symptoms in a Turkish pediatric population

The purpose of the present study was to evaluate obsessive-compulsive disease (OCD) in Turkish Children who had group A beta hemolytic streptococcal (GABHS) infections and those who had not. Thirty-one children and adolescents (the study group) were compared with 28 children and adolescents. The Children's Yale-Brown Obsessive-Compulsive Scale (CY-BOCS) scores were rated between study group and control group. The mean score, obsession and compulsion scores of CY-BOCS in the study group were significantly higher than they were in the control group (P < 0.05). The GABHS infections should be assessed in the etiology of OCD in children. Considering GABHS infections may help the treatment of OCD
