Cannabidiol, from Past to Present: a Review

The cannabis plant contains the naturally occurring substance cannabidiol, also known as CBD. As opposed to its more widely known relative, tetrahydrocannabinol (THC), cannabidiol (CBD), does not possess any psychoactive or euphoria-inducing properties, and is widely regarded as harmless and nonaddictive. Due to its alleged medicinal advantages, which are thought to include pain relief, anxiety reduction, epilepsy management and anti-inflammatory characteristics, CBD has attracted a lot of attention in recent years, in both human and veterinary medicine. The different kinds of CBD products available include oils, tinctures, capsules, lotions, and even edibles in the form of cookies and candy. In the field of veterinary medicine, the use of CBD has become more and more prevalent in recent years, and a formulation of treats for dogs and cats containing varying quantities of cannabidiol have been put on the market. Despite growing in popularity, CBD's legal status is still a little hazy in many nations, and more study is required to fully comprehend both its advantages and disadvantages. This article aims to review CBD’s history, mechanisms of action, potential therapeutic roles as well as adverse effects that have been encountered thus far in clinical studies

Urinary N-Acetyl-Beta-D-Glucosaminidase Index Activity Normal Values in Healthy Wistar Rats

Reference values have a major importance in describing the diversity of healthy individuals variables. These are population reference ranges (RIs) that comprise 95% of the healthy population. The determination of biological markers, like urinary NAG and creatinine, is considered a simple, rapid and non-invasive method for detecting and monitoring renal tubular function under different conditions. Calculation of the urinary NAG index provides a good estimate of the excretion of the two markers over a 24 hour period. An increase of the urinary NAG index may precede increases in standard parameters used in the diagnosis of renal disease, especially in cases of acute tubular lesions. With the purpose of detecting deviations of the urinary NAG index, this study established the reference values in Wistar rats. Urine samples were collected from 100 healthy Wistar rats, 50 males and 50 females. NAG and creatinine were determined, and subsequently the NAG index was calculated for reference value establishing. The mean value of NAG index was found to be 5.81±1.68 (U / g) for healthy females and 4.10±0.90 (U / g) for healthy males

The Effects of Cannabidiol on Canine Epilepsy and Arthritis – a Case Study

Cannabidiol oil (CBD) has gained notoriety in recent years due to its effectiveness as an adjuvant therapy in many pathologies.The purpose of this study is to evaluate the effects of CBD in the management of pain and the associated pathologies of epilepsy and arthritis, on a single subject, a female Labrador, 12.5 years old at the beginning of the study. The therapeutic protocol used was the administration of CBD oil, sublingually, in doses of 2.25 mg/kg/day. Hematology and biochemistry were performed at 3, 6 and 12 months. Radiology was performed before the study began and after 6 months.After the first month, a decrease in the number and severity of epilepsy crises was observed. Beginning with the first 2 weeks of CBD oil administration, the patient was already experiencing an improvement in her mobility along with general pain remittance and the amelioration of her 3rd degree lameness, quantified by the Colorado Pain Scale. After 5 months of CBD administration, with no seizures recorded, phenytoin therapy was ceased. After 8 months, phenobarbital was also excluded from the therapeutic protocol, thus making CBD an independent the rapeutic molecule. CBD appears to be a useful molecule in managing both pain and epilepsy
