How many tools does a veterinarian need to examine an animal?
For a routine examination for most animals, a stethoscope and a digital thermometer are all that's required. However, for animals with chronic disease, a blood chemistry analyzer or a microscope for histopathologic examination of exudates may be necessary.
How successful are the lung cancer treatments?
Treatment for lung cancer depends upon a variety of factors. The most important factors are the histopathologic (diseased tissue) type of lung cancer and the stage of the cancer. Once the stage of the lung cancer has been determined, the oncology team and the patient work together to develop a treatment plan. It is important for lung cancer patients to discuss the value of different forms of therapy with their oncologist. Other factors that affect lung cancer treatment include the patient's general health, medical conditions that can affect treatment (such as chemotherapy), and tumor characteristics.

How do you diagnose mad cow disease?
You can't really quarantine animals that have this illness, since it is a malady that is very hard to predict which animal has it or not, and there are (currently) no methods to test whether a live animal has BSE or not; there are only tests available for testing deceased animals. The only way you can "get rid of" BSE in your herd is to not feed any animal-by products to cattle.
What is the purpose of a ct guided biopsy?
First of all we should define what is a biopsy. It is derived from the root words "bio" (life) and "opsis" (sight), referring essentially to the evaluation of living tissue. A biopsy is an essential tool in the evaluation of disease conditions and helping to determine the characteristics of tissue changes. There are many different ways to obtain biopsy samples and they vary depending upon where the area to be biopsied is located. A biopsy may be as simple as taking a needle and syringe, using the needle to puncture a superficial growth, swelling, abnormality which is easily visualized (so it can be seen that the needle is actually within the area of interest) and withdrawing a sample. This is referred to as a needle aspirate. The sample can then be placed on a slide and evaluated under the microscope, which is termed cytology, from "cyto" (cell) and "ology" (study of). To aid in the visualization of elements of the sample, special stains are usually applied. However, there are times when the area/lesion that needs to be biopsied is not easily visualized and may be inside the body or part of an internal organ. Trying to take a needle biopsy sample without knowing where the needle is going is extremely dangerous as internal organs, structures, or major blood vessels could be punctured leading to severe complications. In addition, there is no guarantee that the area of interest was even sampled as the placement of the biopsy needle was not seen! The use of the CT or other imaging techniques (such as ultrasound) expedite the procedure so it is safely and accurately accomplished. Using imaging, in addition to special biopsy instruments, the progress of the needle can be followed and guided to the exact location where the sampling needs to be done. Once obtained, cytology may be done, but most often the sample will be sent out for histopathologic analysis; "histo" (tissue), "path" (hurt), "ology" (study of). Histopathology is a very effective and sensitive means of evaluating tissue abnormalities. The samples are sent to a pathologist who then has various means of preparing and evaluating the samples in order to provide an accurate diagnosis.
What is the main term of aspiration pneumonia?
Aspiration pneumonia Classification & external resources Aspiration_pneumonia_(2).jpg Histopathologic image of aspiration pneumonia in an elderly patient with debilitating neurologic illness. Note foreign-body giant cell reaction. Autopsy case. H & E stain. ICD-10 J69.0, P24.9 ICD-9 507, 770.12, 770.14, 770.16, 770.18 MedlinePlus 000121 eMedicine emerg/464 Aspiration pneumonia is bronchopneumonia that develops due to the entrance of foreign material that enter the bronchial tree, usually oral or gastric contents (including food, saliva, or nasal secretions).[1] Depending on the acidity of the aspirate, a chemical pneumonitis can develop, and bacterial pathogens (particularly anaerobic bacteria) may add to the inflammation. Causes Aspiration pneumonia is often caused by an incompetent swallowing mechanism, such as occurs in some forms of neurological disease (a common cause being strokes) or while a person is intoxicated. An iatrogenic cause is during general anaesthesia for an operation and patients are therefore instructed to be nil per OS (NPO) for at least four hours before surgery. Whether aspiration pneumonia represents a true bacterial infection or a chemical inflammatory process remains the subject of significant controversy. Both causes may present with similar symptoms. Location The location is often gravity dependent, and depends on the patient position. Generally the right middle and lower lung lobes are the most common sites of infiltrate formation due to the larger caliber and more vertical orientation of the right mainstem bronchus. Patients who aspirate while standing can have bilateral lower lung lobe infiltrates. The right upper lobe is a common area of consolidation in alcoholics who aspirate in the prone position.[2] Depending on the acidity of the aspirate, a chemical pneumonitis can develop, and bacterial pathogens (particularly anaerobic bacteria) may add to the inflammation.

How toxic is indoxacarb 0.05 percent of 0.14 oz to a 40 lb. dog and what are the symptoms of poisoning?
# Animal DataDuPont Steward InsecticideOral LD50: 3619 mg/kg in male ratsOral LD50: 751 mg/kg in female rats (Slight toxicity)Dermal LD50: >5000 mg/kg in rats (Slight toxicity)Inhalation 4 hour LC50: >2.7 mg/L in rats (Very low toxicity)DuPont Steward Insecticide is a slight to mild skin irritant, and is a skin sensitizer, but is not an eye irritant in animals.DuPont Steward Insecticide in high single oral doses caused gait abnormalities, incoordination, hypoactivity, convulsions, tremors, hypothermia, hair loss, labored respiration, discharge, and vocalization in rats.Single oral dosing studies with DPX-MP062 (containing 75% Indoxacarb, active ingredient) to assess potential neurotoxicity were conducted in male and female rats. The NOEL for neurotoxicity was 100 mg/kg for male rats and 12.5 mg/kg for female rats.Repeated oral dosing with DPX-MP062 (containing 75% Indoxacarb, active ingredient) caused mild hemolytic anemia and reduced body weight gain in male and female rats; additionally, female rats experienced weakness and incoordination while male rats exhibited some changes in clinical chemical measurements. The No-Observed-Effect-Level (NOEL) in a 90-day repeated oral dosing study was 100 ppm for male rats and 25 ppm for female rats.Single inhalation exposure to DuPont Steward Insecticide in rats caused lung noise immediately following exposure; no clinical signs were noted during the 14-day recovery period.Based on animal data from DPX-JW062 (containing 50% Indoxacarb, active ingredient), the following chronic effects may occur in animals with Indoxacarb.Ingestion of DPX-JW062 by dogs for one-year caused hemolytic anemia with secondary histopathological changes and decreased body weights. The NOEL for both male and female dogs was 40 ppm. Effects in male and female rats that were fed DPX-JW062 in their diets for two-years include decreased body weight, in addition femalesalso had some hemolysis. The NOEL for the two-year rat feeding study was 60 ppm for male rats and 40 ppm for female rats. Male and female mice fed DPX-JW062 for eighteen months had decreased body weight, in addition females showed signsof neurotoxicity, some mortality, and a few incidences of histopathologic changes in the brain (probably secondary to seizures). The NOEL for the eighteen month mouse feeding study was 20 ppm in male and female mice.Tests have shown that DPX-MP062 (containing 75% Indoxacarb, active ingredient) does not cause genetic damage in bacterial or mammalian cell cultures or in animals.Based on animal data from DPX-JW062 (containing 50% Indoxacarb, active ingredient) Indoxacarb is not considered a carcinogenic or reproductive hazard.Indoxacarb is not considered a developmental hazard. The maternal and developmental NOEL was 2.0 mg/kg.
