Abstract:

Background: Acyclovir [9-(2-hydroxyethoxymethyl)guanine; ACV], an acyclic nucleoside analogue, has shown a potent antiviral activity. It is known to inhibit the replication of herpes viruses including herpes simplex virus type 1 (HSV-1) and type 2 (HSV-2), varicellazoster virus, and Epstein-Barr virus in cell cultures and in animals. ACV is khown to be toxic to gonads,then the aim of the present study was to evaluate effect of ACV on potential fertility in rat. Materials and Methods: In this study thirty-two adult male wistar rats (220 ± 20 g) were randomly divided into four groups (n=8 each) with one group serving as control sham (distilled water i.p.), in the drug treated groups Acyclovir administered (4, 16, 48 mg/kg/day i.p.) for 15 days . 11 days after the last injection four males from each group was placed in an individual cage with two super-ovulated same strain females. The presence of vaginal plugs and as well observation of sperm in the smears in the following morning was an indication, that mating had occurred and this was designated day 1 of gestation. The number of pergnent female rats bred to ACV treated male rats and untreated rats and also the number of offspring was recorded. Results: Female mated by male rats exposed to ACV showed significantly lower pregnancy rate. There were no significant changes in the mean number of the offspring at any dose-level of ACV in comparsion with those of control sham group. Conclusion: Taking collectively, present study suggests that ACV plays negative roles on reproductive system and function in male rats.

ADHD-like behaviour in the offspring of female rats exposed to low chlorpyrifos doses before pregnancy.

The aim of this study was to investigate how chronic low-dose chlorpyrifos exposure of female Wistar rats before and during pregnancy affects behavioural parameters in their offspring. Four months before pregnancy, we exposed three groups of rats to chlorpyrifos doses of 5, 10, and 15 mg kg-1 body weight every day for 30 days, whereas one group received a single 30 mg kg-1 dose on gestational d...

P-52: Acyclovir Induced Sperm and Hormonal Disorders in Male Rats

Background: Acyclovir is asynthetic purin nucleoside analog,which has been reported to be very effective against the treatment of herpes simplex and varicella zoster infections. Acyclovir is known to be toxic to gonads, but available literature fails to provide the indepth analyses of damage.The aim of the present study was to evaluate the effect of Acyclovir on DNA damage and nuclear maturatio...

P-44: Effects of Nano Zinc Oxide Supplementation on Testicular Oxidative Stress in Adult Male Rats Exposed to Endurance Exercise

Background: Physical activity has a range of effects on male reproductive function depending upon the intensity and duration of the activity. Materials and Methods: In order to investigate the protective effects of nano zinc oxide on endurance exercise induced testicular oxidative stress, 30 adult male Wistar rats were randomly divided into the following groups: control group (n=10); exercised ...

Coping strategies in male and female rats exposed to multiple stressors.

Because of the pathogenic effects of chronic stress exposure, it is important to identify factors, such as effective coping strategies, that mitigate stress-induced pathology. Of interest in the present study was the consistency of behavioral responses across a diverse array of stressors. Sixteen male and 16 female Long-Evans rats were assigned to either a stress or control group. The stressed ...
