Question
Lab 9: Immune system What was hypothesized/predicted in the plant extract and human extract experiment? What is a zone of inhibition? What were the results and expected results? (tears have a lot of lysozymes, sweat has some lysozymes, spit encourages bacteria, plants need antibacterial properties to prevent herbivory and also disease) Blood histology: be able to identify erythrocytes, neutrophils, lymphocytes, and monocytes on slides. . . Be able to identify all of the blood cell types using the models Which of the blood cells specialize in phagocytosis? Note: all will do it, but not all have the main purpose to do phagocytosis. Compare leukemia blood vs normal blood smears Reticular fibers function Location and function of . . o Bone marrow o Leukocytes o Thymus o Lymph nodes o Spleen o TonsilsExplanation / Answer
Ques-1:
The plant extracts are derived from the several ‘plants with anti-cancer properties’ to examine their pharmacological effects on the tumor cells. These plants are selected based on the ethnobotanical sources. The molecules can produce pharmacological effects on the human cancer cells. Thus, the antitumor activities are produced by the activity of plant extracts.
The animal extracts to prepare anisera have meticulously done using specific protocols. These antisera are generated from mouse models, horse models to boost immunization in the people.
Ques-2:
We can test the effectiveness of a disinfectant an antiseptic against the bacteria by incubating the microbes in the presence of the test compound (disinfectant or antiseptic). This is also known as “zone of inhibition test.”
The filter papers soaked in the test chemicals are placed in the tryptamine soy agar medium (TSA) containing a specific bacterial strain and the temperature is maintained at 370C.
After 24 to 48 hours, examine the disks for the growth of organism and measure the zone of inhibition.
