HOW TO DETERMINE PCV (PACKED CELL VOLUME)

The Packed Cell Volume (PCV) Test 1. Objective: This is one of the oldest tests done in medical practice. The objective of this test was to determine the percentage of red blood cells (RBCs) in whole blood. It  also helped to assess the blood’s capacity to carry oxygen. ________________________________________ 2. Principle: The test was based on the principle that when blood was centrifuged, the red blood cells settled at the bottom of the tube, forming a packed column. The ratio of the packed RBC column to the total blood column gave the packed cell volume (PCV), expressed as a percentage. ________________________________________ 3. Materials: • Microhematocrit capillary tubes • Microhematocrit centrifuge • Plasticine or sealing clay • Microhematocrit reader • Lancet • Alcohol swab • Cotton ________________________________________ 4. Procedure (Microhematocrit Method): 1. The fingertip was cleaned with an alcohol swab and pricked with a sterile lancet. 2. Blood was collected into ...

ANTIMICROBIAL ABUSE IN LIVESTOCK FARMING

What problem could one encounter while consuming livestock?


First, antibiotics are used to prevent,treat and control bacterial infections in livestock. Just like humans, animals can contract infections, such as pneumonia.


As a case study,Pork is the world's second most consumed meat, accounting for roughly 35% of total meat consumption.


China, the United States, and the European Union are the world's largest pork producers, accounting for roughly 80% of total pork production.


A study published in the Proceedings of the National Academy of Sciences found that pork had significantly higher levels of antibiotics than chicken, beef, and lamb.

Antibiotics are used in the breeding process primarily because they reduce disease and mortality in pigs while also rapidly increasing pig weight.


In the United States, roughly 27.1 percent of Medically important antibiotics are used in the pig industry, and China uses more medically important antibiotics than the United States and the European Union.


According to related reports, the antibiotic content of pork in China is twice that of chicken and five times that of beef.


Overall, medically important antibiotics accounted for 62% of all antibiotics sold for use in food-producing animals in 2015. Approximately 70% of all medically important antibiotics in the United States are sold for use in animals.


Currently, the scientific community is of the opinion that a large number of antibiotics entering the body will increase bacterial resistance, posing potential health risks.


This acquired antimicrobial resistance from animals would then go on to become the leading cause of death from preventable infections in the 21st century .

HOW LONG DOES TETRAHYDROCANNABINOL, THC LAST IN THE BODY? Tetrahydrocannabinol is the principal psychoactive constituent of cannabis and one of at least 113 total cannabinoids identified on the plant.THC is the main psychoactive compound in marijuana. It's what makes people feel "high."  THC and its metabolites are stored in body fat before finally clearing out through the kidneys.  For someone who has used it daily for so long, your body will be completely saturated with the stuff for some time after quitting.  At 83 days, you're pretty much right on the edge of having it out of your system but just aren't quite there yet.  One-time use will usually stay in your system for 5-8 days. If you use cannabis 2-4 times per week and then stop, you'll test positive for 11-18 days. Long-time heavy users should expect positive results for at least 90 days after cessation and even up to 120 days for those who are larger or with a slow metabolism.  HOW TO REDUCE THC IN TH...
