Ursodeoxycholic acid (UDCA), also known as ursodiol, is a secondary bile acid, produced in humans and most other species from metabolism by intestinal bacteria. It is synthesized in the liver in some species, and was first identified in bile of bears of genus Ursus , from which its name derived. [ 8 ]
Hepatic veno-occlusive disease (VOD) or veno-occlusive disease with immunodeficiency is a potentially life-threatening condition in which some of the small veins in the liver are obstructed. It is a complication of high-dose chemotherapy given before a bone marrow transplant or excessive exposure to hepatotoxic pyrrolizidine alkaloids .
For the drugs administered by oral and dermal route, the units of threshold dose are mg/kg body-weight/day (dose of the drug in mg per body weight in kg per day) or ppm (parts per million), while the threshold dose of drugs by inhalation delivery has the unit of mg/L 6h/day (amount of drug in mg in 1L of air, for 6 hours per day).
Post-exposure prophylaxis, also known as post-exposure prevention (PEP), is any preventive medical treatment started after exposure to a pathogen in order to prevent the infection from occurring. It should be contrasted with pre-exposure prophylaxis , which is used before the patient has been exposed to the infective agent.
Antimicrobial use has been common practice for at least 2000 years. Ancient Egyptians and ancient Greeks used specific molds and plant extracts to treat infection. [5]In the 19th century, microbiologists such as Louis Pasteur and Jules Francois Joubert observed antagonism between some bacteria and discussed the merits of controlling these interactions in medicine.

Antivenoms are purified from animal serum by several processes and may contain other serum proteins that can act as immunogens.Some individuals may react to the antivenom with an immediate hypersensitivity reaction (anaphylaxis) or a delayed hypersensitivity (serum sickness) reaction, and antivenom should, therefore, be used with caution.
Additionally, vascular endothelial growth factor (VEGF) levels in the retina were examined and showed lower levels in the ursodoxicoltaurine treated group compared to the control group, whereas no effect in the UDCA treated group. ursodoxicoltaurine and UDCA may suppress CNV formation, which may be associated with its anti-inflammatory effects.
Melioidosis is an infectious disease caused by a gram-negative bacterium called Burkholderia pseudomallei. [1] Most people exposed to B. pseudomallei experience no symptoms; however, those who do experience symptoms have signs and symptoms that range from mild, such as fever and skin changes, to severe with pneumonia, abscesses, and septic shock that could cause death.
