As long as the problem is not directed to sight, by using "human body model" to examine the visual acuity of albino rat, the potential process of eye-brain cooperative action has never been considered. So, if we want to analyze the foundation of our vision, what will we find? Is there a simple network of interconnected neurons that simply passes information from the periphery to the brain? Observation techniques are very complex and sensitive to conformational changes in the eye.
Samples of 75 male albino rats weighing 155 ± 5 grams were selected randomly from a rat group of pet science psychology animal farms at Rohatak's Maharsi-Dyanand College. Rats were randomly assigned to five different groups (15 / group). Identification marks were assigned to each animal and they were housed in a wire cage according to a free feeding schedule. Design Active - Passive Avoidance Device: This device consists of slotted channels. Since there is a gap of 1 cm at the bottom, urine and feces automatically fall. It is divided into two compartments by 1 inch thick wooden walls of length 60 and 30 cm. On the partition wall there is a circular hole with a sliding door that allows the mouse to enter the other compartment. The inner surface of the device can be connected to shock It is covered with aluminum plate
Adolescent female rats are paired with adult male rats, female rats using a model called SCAR (Sexual Attack Reaction), or left for 30 minutes a day in an unfamiliar cage. When raised together with adult male rats, adolescent females are positively fixed and attached while trying to escape. The team found that adolescent female rats not only felt great pressure when male rats tried to climb but also weakened their ability to learn to take care of their offspring. For example, if you are bred with a newly born mouse, females raised with adult male will not give birth or newborn within 17 days. In addition, these female rats retain fewer neoplastic cells in the hippocampus (an area important for memory and learning).
Design: 18 male albino rats were divided into 3 groups. The first group is fully managed. Group II and III rats received a subcutaneous injection of 0.3 mg / kg L-thyroxine (LT 4) daily for 12 consecutive days. On day 13, animals of group III (PTU treatment with hyperthyroidism) were injected with 5 mL / kg propylthiouracil (PTU) and an equal amount of LT4 in Group II animals (for additional 15 days) . Group II animals (control for hyperthyroidism) continued to receive LT4. At the end date (day 28 of LT 4 treatment), the animals were decapitated overnight (12 h) under ether anesthesia and fasted.
