A Love Drug? Oxytocin, the 'Cuddle Chemical' to Scientists, Makes Mothers More
Kind, Say Researchers - ABC News, 1/11/12 - "There
is hope that the hormone could be used to help patients suffering from a range
of psychiatric disorders that affect social interactions, including autism and
schizophrenia ... They found a clear correlation between the levels of
oxytocin and the amount of attention each new
mother paid to her baby. The first trimester of the pregnancy turned out to be
the most important because higher levels of the hormone during that period
coincided with much more bonding and affection after the birth ... At about the
same time as the Israel study, Paul Zak of Claremont University in California
was giving doses of oxytocin, and a placebo, to participants who were instructed
to split a sum of money with a stranger. The results were "overwhelming,"
according to that study. Those given oxytocin offered 80 percent more money than
those given a placebo ... in the first hour or two after getting the hormone,
the monkeys actually became more selfish. It took a couple of hours for them to
become more social and compassionate" -

New
role for hormone oxytocin in brain - Science Daily, 11/2/11 -
"Much of the body's chemistry is controlled by the
brain -- from blood pressure to appetite to food metabolism ... a team of
scientists led by Dr. Gil Levkowitz of the Weizmann Institute has revealed
the exact structure of one crucial brain area in which biochemical commands
are passed from the brain cells to the bloodstream and from there to the
body. In the process, they discovered a surprising new role for the "hormone
of love," showing that it helps to direct the development of this brain
structure ... The scientists showed that oxytocin, one of the two major
hormones secreted in the adult neurohypophysis, is involved in the
development of this brain area already in the embryo. At this stage, the
oxytocin governs the formation of new blood vessels" - Note:

Hormone oxytocin flies off shelves as a his-and-hers sex drug - The
Daily, 10/10/11 - "“Absolutely, it’s worth a try,”
Eric Braverman, a New York physician who recommends an oxytocin supplement
to patients struggling in relationships, told The Daily. “And we know that
people produce less oxytocin as they get older, so for them to stay
intimate, a supplement can be a godsend.” ... But while some couples swear
by the supplement, experts caution that there’s not enough evidence to show
that synthetic oxytocin — the kind sold over-the-counter, as opposed to that
produced by the human body or used by hospitals to induce labor — can
actually impact the brain" - Related article:

Psychologists discover oxytocin receptor gene's link to optimism,
self-esteem - Science Daily, 9/14/11 - "UCLA
life scientists have identified for the first time a particular gene's link
to optimism, self-esteem and "mastery," the belief that one has control over
one's own life -- three critical psychological resources for coping well
with stress and depression ... The gene Taylor and her colleagues identified
is the oxytocin receptor gene (OXTR). Oxytocin is a hormone that increases
in response to stress and is associated with good social skills such as
empathy and enjoying the company of others ... An increase in oxytocin tends
to lead to more social behavior, especially under stress and especially in
females, earlier research has indicated ... OXTR likely interacts with other
genes"

Low Oxytocin Linked to Postpartum Depression - WebMD, 5/11/11 -
"Sometimes called the “cuddle hormone” or the
“hormone of love,” oxytocin has been the subject of much research interest
for its ability to foster feelings of bonding and attachment ... New fathers
who are given a whiff of oxytocin nasal spray, for example, are more likely
to encourage their children to explore during playtime and are less likely
to be hostile, compared to fathers given a placebo ... Lower oxytocin levels
before birth were associated with a greater risk of postpartum depression"

hormone' may treat daily headaches - MSNBC, 12/20/10 -
"Of patients given a dose of oxytocin as a nasal
spray, 50 percent reported their headache pain was reduced by half, and an
additional 27 percent of these patients reported no pain after four hours.
By comparison, 11 percent of patients who were given a placebo spray said
their headache pain was cut by half after four hours, and none reported
complete pain relief"

'Love
Hormone' could help treat severe mental illness - MSNBC, 12.3.10 -
"A small study published Oct. 1 in the journal
Biological Psychiatry found that patients with schizophreniawho took
oxytocin for three weeks along with their regular antipsychotic medication
improved in their symptoms and hallucinated less than those who took a
placebo with their antipsychotic ... Oxytocin is also being tested in
clinical trials as a treatment for depression, borderline personality
disorder and alcohol withdrawal ... One hypothesis is that oxytocin dampens
the activity of the brain's fear center, the amygdala, thereby easing stress
and anxiety ... Because of oxytocin's proposed blunting effects on the
amygdala's activity, scientists have also hypothesized it would help those
with PTSD ... oxytocin's trust effect could help those with schizophrenia,
making them less paranoid ... researchers are investigating oxytocin's
potential benefit for a number of other ailments, including headaches,
constipation and skin damage"

Oxytocin makes people trusting, but not gullible, study suggests -
Science Daily, 8/24/10 - "Oxytocin (OT) is a hormone
that plays an important role in social behavior—it has even been nicknamed
“the love hormone” and “liquid trust.” Increased levels of OT have been
associated with greater caring, generosity, and trust ... volunteers who
received the OT nasal spray were more trusting of the computer and the
reliable partners—that is, they offered more money to the computer and the
reliable partner than did volunteers who received the placebo nasal spray.
However, OT did not have an effect when it came to sharing with a seemingly
unreliable partner—the volunteers were not generous towards a potentially
unreliable partner, regardless of which nasal spray they received. ... These
findings suggest that OT fosters trust, but not gullibility: OT may make
individuals more trusting, but only in certain situations"

line is it improved the ability of people to learn when they had positive

Abstracts:
- A
link between oxytocin and serotonin in humans: Supporting evidence from
peripheral markers - Eur Neuropsychopharmacol. 2012 Jan 30 -
"Pharmacological studies indicate a functional
interaction between the serotonergic and oxytocinergic systems. In
particular, some selective serotonin (5-HT) reuptake inhibitors, such as
citalopram and fluvoxamine, seem to exert part of their antidepressant
effects through oxytocin (OT) release. Further, the administration of
fenfluramine, a serotonergic agonist, to healthy subjects increases plasma
OT levels. Interestingly, immunocytochemical and double-immunofluorescent
techniques revealed a high degree of overlap between 5-HT transporter (SERT)-labeled
fibers and OT-containing cells ... This result represents the first evidence
of an interaction between OT and SERT, as measured by [(3)H]-Par binding, at
peripheral levels in humans. Given the several activities mediated by both
OT and 5-HT, such a relationship might provide new perspectives and insights
into psychiatric disorders and/or social relationship disturbances, as well
as novel treatment strategies overcoming and/or integrating the serotonergic
paradigm"

Oxytocin
Mediates Social Neuroprotection After Cerebral Ischemia - Stroke. 2011
Sep 29 - "In the present study, adult male mice were
socially isolated (housed individually) or socially paired (housed with an
ovariectomized female); social pairing increased hypothalamic OT gene
expression. To determine whether a causal relationship exists between
increased OT and improved stroke outcome, mice were treated with exogenous
OT or OT receptor antagonist beginning 1 week before induction of
experimental stroke via middle cerebral artery occlusion ... Relative to
social isolation, social housing attenuated infarct size, neuroinflammation,
and oxidative stress following experimental stroke; the neuroprotective
effect of social housing was eliminated by receptor antagonist treatment. In
contrast, administration of OT to socially isolated mice reproduced the
neuroprotection conferred by social housing. We further report evidence for
a direct suppressive action of OT on cultured microglia, which is a key
instigator in the development of neuroinflammation after cerebral ischemia"
