Card Set Information
What is diff in terms of phosphate homeostasis with PTH and Vitamin D?
PTH--increases Phosphate exretion in kidney
Vitamin D-increases phosphate absorption in intestine
4 PTH function
ca and po4 resorption
increase po4 exrection in kidney
increases ca absorption in DCT
upregulate alpha 1 hydroxylase--which activated VITAMin D which reabsorbs ca from intestine
Coniviptan --blocks V1 and V2
ADH and oxytocin are produced where?
supraoptic and paraventricular nuclei
Tx for pit. adenoma
octerotride--somatostatin analog block GH
In case of hypo. ant. pit. what hormone goes down first?
Which one should be treated?
GnRH--sexual dysfunction ensues
ACTH def. should be treated with cortisol to maintain sugar level and BP
TX for Lithium induced DI?
Tx for DI?
Somatostatin has 2 roles in two diff places? WHat releases it?
hypothalamus--blocks GH and TSH
D cells of pancreas- stop insulin, glucagon, pancreatic enzymes
GI-block gastrin, pepsinogen
What effect does lithium have on Na level ?
decreases it via displacement

2 Drugs that cause DI?
2 Tx for neurogenic DI?
desmopressin-releases vwf factor from endothelium
3 Strategies for post menopausal osteoporosis?

low ca---> high PTH
Coniviptan blocks which receptors?
V1 and V2
What ADh receptor does Vasoconstriction?
Measurment of what tells you about levels of GH?
Somatomedin c /IGF-1
Excess GH production in Kids?
In normal pts, glucose has what effect on GH?
low glucose high GH
high Glucose, low GH
GH receptor antagonist for gigantism?
Drug to diagnose ACTh deficiency?
Metyrapone--inhibit cortisol production which should increase acth
Somatostatin analog for acromegaly, carcinoid, glucagonoma, gastrinoma?
5 Releasing HR from Hypothalamus?
How to diagnose GH deficiency?
give insulin--> low glucose--> should increase GH
3 Causes for Hypo. Ant. Pit?
