Ciprofloxacin Does Not Exert Nephrotoxicity in Rats

Ciprofloxacin, a member of the fluoroquinolone class, is an antibiotic used as a treatment for infections including the Anthrax bacteria. Studies concerning the safety and efficacy of ciprofloxacin have been controversial with respect to nephrotoxicity. Using rats orally treated with ciprofloxacin (400mg/kg/d), the effects of this drug were analyzed measuring several indications of nephrotoxicity: -NAG, creatinine, blood urea nitrogen, and sodium and potassium levels in blood samples. Additionally, histological analyses were performed. -NAG values, a measure of early renal damage, were significantly increased after 4 and 7 days of treatment (p = 0.001 and p = 0.004, respectively) compared with control rats. However, 7 days post-treatment, -NAG values decreased to control levels indicative that adaptive responses were induced to prevent nephrotoxicity. These results indicate that ciprofloxacin in doses comparable to those commonly prescribed does not induce nephrotoxicity. Altogether, they further support the idea that ciprofloxacin can be safely use

sChronic administration of sildenafil improves erectile function in a rat model of chronic renal failure

The relationship between erectile dysfunction (ED) and chronic renal failure (CRF) has been reported in several studies. This study aimed to investigate whether the chronic use of sildenafil could enhance the erectile capacity in CRF-induced rats. In addition, we assessed the effect of that treatment on certain molecules, which have been suggested to play crucial roles in erectile physiology and CRF-related ED as well. Three groups of animals were utilized: (1) age-matched control rats, (2) CRF-induced rats, (3) CRF-induced rats treated with chronic administration of sildenafil (5 mg kg−1 p.o. for 6 weeks [treatment started after 6 weeks of CRF induction]). At 3 months, all animals underwent cavernosal nerve stimulation (CNS) to assess erectile function. Penile tissue advanced glycation end products (AGE′s)/5-hydroxymethyl-2-furaldehyde, malondialdehyde (MDA), cGMP (ELISA), inducible nitric oxide synthase (iNOS) and neuronal NOS (nNOS) (Western blot) analyses were performed in all rat groups. CRF-induced rats had a significant decrease in erectile function when compared to control rats (P < 0.05). The increase in both intracavernosal pressure (ICP) and area under the curve of CRF-induced rats treated with sildenafil (Group 3) was greater than CRF-induced rats (Group 2). Additionally, sildenafil treatment decreased AGE, MDA and iNOS levels, while it preserved nNOS and cGMP contents in CRF-induced penile tissue. Decreased AGE, MDA, iNOS and increased nNOS, cGMP levels at the sildenafil-treated group increased both ICP and Total ICP to CNS, which led to improve erectile function in CRF-induced rats. The results of the present study revealed the therapeutic effect of chronic sildenafil administration on erectile function in CRF-induced rats

Prevalence of cervical cytological abnormalities in Turkey

Objective: To evaluate retrospectively the prevalence of cervical cytological abnormalities in patient records obtained from healthcare centers in Turkey. Method: Demographic characteristics and data on cervical cytological abnormalities were evaluated from patients who underwent flap tests in healthcare centers in 2007. Results: Data were collected from 33 healthcare centers totaling 140 334 patients. Overall, the prevalence of cervical cytological abnormalities was 1.8%; the prevalence of ASCUS, ASC-H, LSIL, HSIL, and AGC was 1.07%, 0.07%, 0.3%, 0.17%, and 0.08%, respectively. The prevalence of preinvasive cervical neoplasia was 1.7% and the prevalence of cytologically diagnosed invasive neoplasia was 0.06%. Conclusion: The abnormal cervical cytological prevalence rate in Turkey is lower than in Europe and North America. This might be due to sociocultural differences, lack of population-based screening programs, or a lower HPV prevalence rate in Turkey. (C) 2009 International Federation of Gynecology and Obstetrics.
