Morphologic evidence for vaginal toxicity of Delfen contraceptive cream in the rat

Toxicology Letters
L Tryphonas, H S Buttar


The morphologic effects of Delfen contraceptive cream on the female genital tract were evaluated in young female rats given a single per vaginum application (0.1 g/100 g) of this spermicidal agent. Control rats received intravaginal instillates of 0.1 ml/100 g of physiological saline. Immediately after dosing, the vulvas of one-half of the treated and control females were shut by metallic clips to prevent leakage of the material. The females were killed 24 h post-treatment. The genital tracts of all control females were unremarkable. Treated females, with or without vulvar labial apposition, developed acute cervico-vaginitis of varied intensity, but as many as half of those without labial apposition failed to develop any pathologic changes. It was concluded that Delfen cream is capable of causing genital tract injury in rats similar to that induced by an aqueous solution of the active ingredient, nonoxynol-9, and that the incidence of this effect is enhanced if leakage of the cream is prevented by application of vulvar clips.

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Neural Activity: Imaging

Imaging of neural activity in vivo has developed rapidly recently with the advancement of fluorescence microscopy, including new applications using miniaturized microscopes (miniscopes). This feed follows the progress in this growing field.

The Tendon Seed Network

Tendons are rich in the extracellular matrix and are abundant throughout the body providing essential roles including structure and mobility. The transcriptome of tendons is being compiled to understand the micro-anatomical functioning of tendons. Discover the latest research pertaining to the Tendon Seed Network here.

Myocardial Stunning

Myocardial stunning is a mechanical dysfunction that persists after reperfusion of previously ischemic tissue in the absence of irreversible damage including myocardial necrosis. Here is the latest research.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.


Incretins are metabolic hormones that stimulate a decrease in glucose levels in the blood and they have been implicated in glycemic regulation in the remission phase of type 1 diabetes. Here is the latest research.

Long COVID-19

“Long Covid-19” describes illness in patients who are reporting long-lasting effects of the SARS-CoV-19 infection, often long after they have recovered from acute Covid-19. Ongoing health issues often reported include low exercise tolerance and breathing difficulties, chronic tiredness, and mental health problems such as post-traumatic stress disorder and depression. This feed follows the latest research into Long Covid.
