What effect will the saline injections have on the control rat's vertebral bone density?

The saline injections will not change the rat's vertebral bone density (indicated by an unchanging T score).

What effect will the saline injections have on the control rat's vertebral bone density quizlet?

The saline injections will not change the rat's vertebral bone density.

What effect did saline injections have on the control rat?

The rats all had osteoporosis since estrogen loss weakens bone growth, which is why they had baseline T scores. What effect did the administration of saline injections have on the control rat? How well did the results compare with your prediction? When saline ejection were administered, no effect occured.

What effect did the administration of calcitonin injections have on the calcitonin treated rat What effect did it have on bone density?

Calcitonin treatment caused a further increase in osteocalcin and P1NP in OVX rats. Calcitonin increases Wnt10b and bone formation but decreases bone resorption in ovariectomized osteoporotic rats.

Which of the following improved the vertebral bone density of the rats?

Parathyroid hormone (1-34) increases vertebral bone mass, compressive strength, and quality in old rats. Bone. 1995 Dec;17(6):507-11. doi: 10.1016/8756-3282(95)00371-1.

What effect will the calcitonin injections have on?

Prolonged administration of parenteral calcitonin, by injections of 100 IU every 1 or 2 days, can prevent postmenopausal or postovariectomy bone loss, and is also able to increase trabecular bone mass among patients presenting an established osteoporosis.

What is the reason that all the rats that were injected with PTU have the lowest metabolic rates?

PTU lowered the normal rat's metabolic rate. Why? Because PTU inhibited the production of thyroid hormone, and less thyroid hormone means a lower metabolic rate.

What do you think will happen after you inject PTU into three rats?

What do you think will happen after you inject PTU into the three rats? The normal rat will become hypothyroidic and develop a goiter.

Which of the rats developed a goiter after injection with PTU?

The Hypox rat became hyperthyroidic and developed a goiter, which is similar to the normal rat. The dose was too large. What was the effect of propylthiouracil (PTU) injections on the normal rat's BMR?

Why was saline injected into the control animals?

Additional measurement of locomotor activity in actometers is needed to check whether drugs used in experiments with elevated plus-maze alter locomotor activity. Injection of saline significantly shortened the latency of reaching one of the closed arms from the free end of an open arm.

What was the effect of TSH on the Thyroidectomized rat?

There was no effect on the thyroidectomized rat's BMR with the injection of TSH because there was no thyroid gland to stimulate.

What are the dangers of taking estrogen?

The health risks of HRT include: Increased risk of endometrial cancer (only when estrogen is taken without progestin) For women who have had a hysterectomy (removal of the uterus), this is not a problem. Increased risk of breast cancer with long-term use. Increased risk of cardiovascular disease (including heart attack ...

Does calcitonin affect bone formation?

Calcitonin inhibits bone removal by the osteoclasts and at the same time promotes bone formation by the osteoblasts.

What hormones will be missing in the rat that was Hypophysectomized?

If an animal has been hypophysectomized, what effect would you expect to see in the hormone levels in its body? TSH levels will be missing because the pituitary gland is removed, so decreased metabolic rate.

How does osteoblasts affect bone density?

First, special bone cells called osteoclasts break down bone. Then, other bone cells called osteoblasts create new bone. Osteoclasts and osteoblasts can coordinate well for most of your life. Eventually, this coordination can break down, and the osteoclasts begin to remove more bone than the osteoblasts can create.
