Evaluation of intratesticular chlorhexidine gluconate for chemical contraception in dogs

Objective:To investigate the contraceptive effect of intratesticular injection of chlorhexidine gluconate in dogs and compare it with that of zinc gluconate neutralized with arginine.Methods:Twenty-four sexually mature male mongrel dogs were randomly divided by replicate into four groups(n=6 per group).GroupⅡreceived intra-testicular injection of 2 mL zinc gluconate(10 mg/mL)neutralized with arginine.GroupⅡreceived intratesticular injection of 2 mL chlorhexidine gluconate(5%w/v).GroupⅢreceived intratesticular injection of 2 mL chlorhexidine gluconate(4%w/v).GroupⅣdid not receive any treatment and served as the control group.Testicular morphometry was conducted on day 0,7,15 and 30 after treatment.Semen was collected and evaluated on day 0 and 30.Data were analyzed using repeated measures analysis of variance.Results:There was no difference in the mean values of various parameters between dogs treated with zinc gluconate and those treated with chlorhexidine gluconate at any of the time points.In dogs treated with zinc gluconate or chlorhexidine gluconate,there was a significant increase in the testicular morphometric parameters on day 7 followed by a significant reduction thereafter(day 15 and 30).In contrast,there was no change in any of the parameters in the control untreated dogs during the course of the study.Compared to the pre-treatment values,the mean scrotal circumference and the mean paired testicular volume and testicular weight on day 30 were significantly lower in the treated dogs.Semen samples collected on day 30 from treated dogs were found to be azoospermic,whereas no change in semen quality was observed in the control untreated dogs.Conclusions:Intratesticular injection of chlorhexidine gluconate(5%w/v and 4%w/v)is equally as effective as zinc gluconate neutralized with arginine for chemical contraception in dogs.

Skin Disinfection with 2% Chlorine Gluconate-Adine in Autologous Peripheral Hematopoietic Stem Cell Transplantation Patients

Background: Autologous peripheral blood hematopoietic stem cell transplantation is widely used in the treatment of malignant lymphoma. Patients are prone to infection during the transplantation immune deficiency period. There has been a lot of clinical research into how to better manage this period of vulnerability. Objective: This study aims to investigate the efficacy of 2% chlorhexidine gluconate (CHG) for skin disinfection in patients undergoing autologous hematopoietic stem cell transplantation (HSCT) and observe any adverse reactions. Methods: A total of 106 patients receiving autologous hematopoietic stem cell transplantation from November 2019 to December 2020 in our district were selected as the control group. From January 2021 to January 2022, 106 patients with autologous hematopoietic stem cells were included in the experimental group. The control group used the immersion bath method. The experimental group was treated with an improved scrub bath method (including 3M 2% chlorhexidine gluconate medical sanitary wipes to wipe the whole skin once). Results: The bacteria-carrying rate of the improved method (37.74%) was significantly better than that of the traditional soaking method (72.64%), and the difference was statistically significant (P Conclusion: The improved bath/wipe method has a significant positive effect on skin disinfection for patients undergoing HSCT.
