PubHealth.info® (a subsidiary of PakMed) presents scientific information mainly based on abstracts of articles published on a variety of public health issues/topics, particularly encompassing population planning, disease prevention, maternal and child health, and communicable and non-communicable diseases (like HIV AIDS, malaria, etc) that are affecting a significant portion of population in developing and developed countries. Here you can find abstracts of articles published on a variety of public health topics under category "Contraception (Birth Control) and Family Planning". Contraception (birth control) is a regimen of one or more actions, devices, or medications followed in order to deliberately prevent or reduce the likelihood of a woman becoming pregnant or giving birth. Therefore contraception is the utilization of various and sundry surgical procedures, devices, practices, agents, or drugs with the intention of preventing conception or impregnation (pregnancy). Methods and intentions typically termed birth control may be considered a pivotal ingredient to family planning. Birth control is a controversial political and ethical issue in many cultures and religions, and although it is generally less controversial than abortion specifically.

ABSTRACT

A prospective study to evaluate the extent of altered sympathetic nervous system activity in relation to oral

contraceptive (OC) hypertension, as reflected by changes in dopamine-beta-hydroxylase (DBH) activity, is presented.

41 OC users and 12 controls were examined for precontraceptive and postcontraceptive levels of blood pressure,

plasma renin activity, DBH activity, and changes in body weight. Increased, but normotensive, blood pressure was

observed in 44% of the OC users, and 17% showed obvious hypertension. Patients with OC-produced increases in

arterial pressure also had significant increases in DBH activity (p less than .05). The positive values of mean arterial

pressure in relation to DBH activity were significantly higher for OC users than the negative values found in the

control group (p less than .05). It is speculated that OCs cause a rise in circulating brain substrate that results in a

simultaneous increase of angiotensin 2 generation, and thus an increased peripheral arterial pressure and

circulating DBH activity. (PubHealth.info Document ID: CONT7T 3061-06)
