Respon Hormon

Page 13: 2009 HORMON

Hormon Oxytocin• Secreted by hypophysis posterior Uterine smooth mucle contract by release Prostaglandin & leucotrine, also G protein reseptor coupled calcium phosphoinositol.

• Contraction myoepithel sorounding alveoli of mamary gland Milk ejection

• High concentration antidiuretic effect

Fungsi Oxytocin :Labor induction

Toxicity rare, excessive uterine contract foetal distress, rupture uterine, placental abruption

Page 14: 2009 HORMON

Vasopressin (ADH)Release by hipophysis posterior

untuk terapi diabetes insupidus. Reseptor V1 terdapat pada pembuluh darah, trombosit, ginjal melibatkan fosfolifase C vasocontricsiReseptor V2 sel ductus coligentes merangsang adenylcyclase. peningkatan permiabilitas membran sel ductus.

HISTAMIN & ANTIHISTAMINHISTAMIN & ANTIHISTAMIN

Histamin Histamin Histos = Jaringan Histos = JaringanDitemukan Ditemukan 1937 (Sir Henry Dale) 1937 (Sir Henry Dale)Peranan : Peranan : Alergi, Imflamasi, Alergi, Imflamasi, Sekresi Sekresi

asam lambung dan kelenjarasam lambung dan kelenjar Sistem Sistem

cardiovasculer dan cardiovasculer dan Sistem pencernaan.Sistem pencernaan.Dibentuk : asam amino Histidin Dibentuk : asam amino Histidin mllmll histidin dekraboxilase histidin dekraboxilaseDiinaktivasi oleh transferase dan Diinaktivasi oleh transferase dan E. coli.E. coli.

Page 18: 2009 HORMON

Jaringan penghasil dan penyimpan :Lung, Kulit, GIT dan Basofil (darah).

Release Histamin :1. Imunologis reaction2. Cel destruction (toxin bacteri, trauma, gigit insecta, cold)3. Drug used Morfin,Penicillin, Tetracyclin ect.4. Radiasi, 5. Chemical toxicity,detergent .

Page 19: 2009 HORMON

Histamin Receptor ada 4 (H1,2,3 & 4)

Terpenting Receptor H1 & H2H1 GIT, Urology, Cardiovasculer, Otak Endothel, limfosit

H2 Exocrin gland ; HCl, Pancreas, Saliva, Bronchus.

H3 Pada Otak (presinap) sintesis & release histamin di otak.

H4 Pada Imun Sistem

Page 20: 2009 HORMON

EFEK HISTAMIN1. Pada sistem saraf sensorik nyeri &

gatal2. Pada Sistem Cardiovasculer Tensi sangat

turun (vaso dilatasi arteriol & vena) hanya diantagonis physiologis. Permiabilitas kapiler meningkat, Cor tidak banyak berpengaruh

3. GIT diare, Asam lambung meningkat4. Bronchus Constricsi, Sekresi Kel

meningkat5. Intradermal triple respon Lewis

(odema, flare, merah merata)

Page 21: 2009 HORMON

PENGGUNAAN HISTAMIN1. Tes fungsi paru2. Sekresi asam lambung3. Integritas saraf sensoris

Lepra4. Pheocromocytoma kel Adrenal.

Kontra Indikasi Asma bronchial & Hipotensi

Page 22: 2009 HORMON

HISTAMIN ANTAGONIS1. Antagonis Fisiologis :

Adrenalin intravena, pada pemberian i.m. muncul efek reseptor beta2 terjadi vasodilatasi menyebabkan nekrosis jaringan.

2. Penghambat Release Histamin :Chromolin, Beta2 agonis spt.Salbutamol, metaproterenol, terbutalin, ritodrin,

3. Antihistamin
