penetration
The penis entering the female reproductive tract.

pemphigus vegetans
A benign variant of pemphigus vulgaris with two classifications: the Neumann type which may begin and end as PVU and Hallopeau which is thought to be more of a benign form.

pemphigus foliaceus
The most common form of pemphigus recognized in the dog...also seen in the horse and other species.

Lice infestation

pediatric administration set
An adminstration set for intravenous fluid administration. The set has a spike to penetrate the container of fluids, a drip chamber and a long flexible tube that connects to the patient's catheter. The drip set drips 60 drops to deliver one ml of fluid. The drops form in the drip chamber through a rigid needle-like structure. This needle-in-the-drip chamber identifies a pediatric drip set.

Pavletic
A surgical technique used to repair lid defects using skin from the lip.

peak milk
Maximum daily milk yield during lactation. Good peak yield is 100-120 lbs and occurs between 60-90 days in milk.

partial parenteral nutrition
Providing energy and nutritional supplementation to a patient at 50 to 70% of the patient's nutritional needs.

Measure of the diameter of granular feed materials and/or the length of roughage fragments. Particle size can affect mixing of feed ingredients and digestion rate.

parturition
Birth.

parturition
Giving birth.

parturition
The process of giving birth.

paroxysmal
The sudden onset of a symptom that reoccurs. For example paroxysmal seizures begin suddenly and occur more than once.

Inflammation of the nail fold.

parity

parasympathomimetic effects
A drug that produces effects similar to the effects produced by stimulation of parasympathetic nerves.

parasitism
Denotes organisms which survive and persist on or within another living organism. The parasite usually does not harm the animal. The most successful parasites achieve a balance whereby both the parasite and host animal survive. Among the parasites found on or within animals are bacteria, protozoans, fungi, mycoplasmas, rickettsia, and viruses.

parasiticide

parasitism
A specific type of relationship between different organisms, where one organism benefits at the expense of another.

paraphimosis
The inability to retract the penis back into the prepuce. Paraphimosis has been reported following semen collection.

paraphimosis
Paraphimosis is when the penis is extruded from the prepuce and cannot be returned to its normal position. This may occur following breeding or sexual excitement such as being kenneled next to a bitch in heat, or by a traumatic fracture of the os penis.

parakeratosis
Abnormal process of cornification.

paralysis
Abnormal function of nerves resulting in an inability to walk.

paradoxical CSF acidosis
Paradoxical CSF acidosis is a condition caused by the administration of a large amount of bicarbonate to an acidotic patient, which will result in neurologic dysfunction. When one gives bicarbonate, the equation is shifted towards the left of the screen, towards the generation of CO2. CO2 is very diffusible, and will diffuse across the blood brain barrier and then shift the equation in the cerebral spinal fluid towards the right with a generation of hydrogen ions. Even though additional bicarbonate is being generated in the CNS, the neurons perceive the increase in hydrogen ions and malfunction. The bicarbonate that was administered IV cannot cross the blood brain barrier.

papule
A small solid elevation of the skin. Larger lesions are called nodules or tumors and if flat, a plaque.

parabasal cell
A small and round cell with a large and distinct nucleus. Parabasal cells, along with red blood cells (RBCs), are present during proestrus.

parabasal cell
Epithelial cells exfoloiated from the vagina during proestrus. The cells are small and round with large and distinct nuclei. The total area of the cytoplasm of the parabasal cell is smaller than the nucleus.

PAO2
The concentration of oxygen in the blood.

palpebrae
Eyelids

palpebral
Pertaining to the eyelids.

palpebral fissure
The opening between the eyelids.

palpebral or blink reflex
Used to assess sensation and the ability to close the eyelids.

panniculitis
Inflammation of subcutanious fat. Several proposed causes and is sterile in some breeds such as the Dachshund.

pannus
Chronic superficial keratitis presumed to be immune-mediated.

palpation
To examine something by touching and feeling it.

pain
An unpleasant sensory and emotional experience which may cause tissue damage.

palatability
The appeal and acceptability of feedstuffs. Affected by the taste, odour, texture and temperature of the feed.

palliative treatment
Palliative treatment is given to patients with untreatable diseases in order to make them more comfortable. Includes a combination of supportive and symptomatic treatments.

packed RBC
Red blood cells from which much of the plasma has been removed. Used to provide RBCs to patients that may not be able to handle a large fluid load, for example patients with cardiac disease. Separation of cells from plasma also allows for early freezing of the plasma to preserve labile coagulation factors.

ovulation
The release of an egg or eggs from the ovary.

ovulation
The process of releasing eggs (ova) from the ovary.

Oxyglobin
A red blood cell substitute made from polymerized bovine hemoglobin.
