The

United

States

government

’

s

Office

of

Research

on

Women

’

s

health

is

observing

its

tenth

anniversary.

During

those

ten

years

it

has

made

important

discoveries

about

differences in the

health of

men

and

women.

Studies

organized

by

the

Office

of

Research

on

Women

’

s

Health

have

shown

that

differences

between

men

and

women

can

influence

medical

treatment.

For

example,

researchers

learned

that

men

and

women

can

react

differently

to

a

heart

attack.

Men

usually

have

chest

pain.

But

women

may

not.

Instead,

they

may

suffer

pain in the abdomen

. They also may

have

stomach

sickness

and

feel

very

tired. Women may not recognize that

they are having a heart attack.

Research

also

has

shown

that

the

brains

of

men

and

women

use

the

chemical

serotonin

differently.

Serotonin helps prevent the condition

of

continued

severe

sadness

called

depression.

Men

’

s

brains

use

serotonin much more effectively than

women

’

s

brains

do.

This

may

help

explain why women suffer

depression

two

or

three

times

more

often

than

men do.

Other research

shows

that alcohol

affects

men

and

women

differently.

Men

and

women

in

one

experiment

drank

the

same

amount

of

alcoholic

drinks.

Then

researchers

measured

their

blood

for

alcohol

levels.

The

women

had

higher

levels

of

alcohol

in

their

blood

.

Women

produce

less

of

substance

called

gastric

alcohol

dehydrogenase.

This

causes

them

to

break down alcohol

more slowly

than

man.
