Healing of Skin Wounds in Rats Using Creams Based on Symphytum Officinale Extract.

Rosmarinic acid is a well-known natural antioxidant and anti-inflammatory compound, and it is one of the polyphenolic compounds found in comfrey plants. Comfrey root also contains allantoin, which helps with new skin regeneration. This study aimed to investigate the healing and skin regeneration process of skin wounds in Wistar rats using creams based on comfrey extract and to correlate the results with active compounds in the extract. The obtained results showed that comfrey root is rich in bioactive compounds, including allantoin, salvianolic acid, and rosmarinic acid, which are known for their great free radical scavenging activity, and the high antioxidant activity of the extract may be mainly due to these compounds. The obtained extract has an antimicrobial effect on Staphylococcus aureus (1530.76/382.69), Escherichia coli (6123.01/6123.01), and Pseudomonas aeruginosa (6123.01/6123.01). The macroscopic evaluation and the histological analysis of the skin defects 14 days after the intervention showed faster healing and complete healing in the skin excisions treated with oil-in-water cream with 20% extract of comfrey as the active ingredient.

Current Aspects Regarding the Clinical Relevance of Electroacupuncture in Dogs with Spinal Cord Injury: A Literature Review.

In recent years, the use of acupuncture and electroacupuncture has been increasing as more clinical research has been conducted showing positive results in the treatment of animals, particularly dogs. Electroacupuncture is a more complex and specific acupuncture technique that involves electrical stimulation on acupuncture needles. Most of the studies have shown that the beneficial effects of electroacupuncture are more evident than in acupuncture alone. This review included studies focused only on dogs with spinal cord injury. Research facility animals (mice, rats, and rabbits) were avoided. Titles and abstracts of identified articles were read, and outlines were made to be better understood. Clinical applications are discussed and suggested in each section. When specialists use this method, electroacupuncture can be an excellent complementary therapy for veterinary patients' pain control.
