Apothecary bottles found in a collectibles shop

// August 21st, 2010 // No Comments » // Drugs

About a week ago I was in Gulgong, a small town in New South Wales near the wine region of Mudgee. The main road was spelled Mayne Road, and was brown stone rather than tarmac. Along the footpaths were old stone troughs for watering horses. Key landmarks included the Ten Dollar Motel and the Gulgong Butchers Cafe. It was an old gold mining town which had lost its gold but kept its rural charm.

Wandering the streets I came across a collectibles shop filled with coloured glass jugs and gold rimmed plates. Amongst the copper kettles I found these old bottles from an apothecary, dated around the 1800′s I believe.

Old Apothecary Bottles

The craftsmanship is stunning, and they teased my imagination. What were these drugs used for? What did they look like, when those bottles were filled, and who was the chemist who filled them?

I have since looked into some of the medicines written on the bottles.

Iodoformum is now called tri-iodomethane (CHI3). The crystals are lemon yellow and have a disagreeable odour and taste. I think it was used to treat tuberculosis, and is still used in homeopathy for a range of ailments. Hexamine may have been mixed with hippuric acid to make methenamine hippurate, which was used to treat lower urinary tract infections. Salol was a white powder derived from salicylic acid, the active ingredient in willow bark, which we take as acetylsalicylic acid in asprin. It was used to reduce pain and fever. Menthol you probably recognise from chest rubs. It comes from mint oil, though it can be made synthetically. As well as clearing sinuses it can ease sore throats and muscle pains, and is one of the ingredients in tiger balm.

While researching I found an issue of the British Medical Journal from September 5, 1885 which is an interesting read.

Hallucinogenic drugs, animal studies and explosm

// May 18th, 2010 // 3 Comments » // Drugs, Just for Fun

So I have had a really busy week in the lovely sunshine coast, and haven’t had a chance to track down the quality science content you know and love. Instead, I have comics of drugs.

WAIT!!! THIS IS SCIENCE! Because sometimes scientists give hallucinogenic drugs to animals to see what happens to them, and to find out how the drug works. Studying hallucinogens can give insights into how the mind works and manages itself.

There are a few famous cases of animal drug studies. The first is the spider web experiment, where spiders were given LSD, caffeine, cannabis or mescaline and the resulting webs were photographed. Another one is the elephant on acid, which happened in the 60′s (or 70′s) when LSD was new and being tried on EVERYTHING. They tried giving it to an elephant at about 400 times the human dose to see if it would go into musth, if it did it would prove LSD induced a kind of psychosis. The elephant didn’t go into musth, it actually died. And they were in a zoo and everything, not cool.

So here are the drug comics. Enjoy!

Absinthe drinking makes Homer something something

// January 15th, 2010 // 6 Comments » // Drugs, Poisons

When I was but a lass, freshly ID’d and able to finally hit the local tavern, there was a rumour around that Absinthe was THE drink if you wanted to get drunk fast, and as a bonus, if you could get the proper stuff, it causes hallucinations. OMG terribly exciting. I could feel jolts of electricity down my spine as I tremulously ordered (with much nudging from my friends) a round of Absinthe.

And oh, the DRAMA of it all! Green liquid, a sugar cube on a special spoon, and all of it on fire! We could only afford one each, before our pockets resolutely returned us to ordering jugs of Sangria. The bitter licorice taste lingered on though, and we were rollickingly tipsy.

Ah, the folly of youth. ‘Tis all a lie!

At the core of the myth is that Absinthe contains essential oil from the Wormwood plant, which is psychoactive and hallucinogenic. It’s true that Wormwood does contain thujole, which is a GABA antagonist (it blocks the effect of the neurotransmitter GABA), but it’s more likely to cause seizures than hallucinations. Also the amount of thujole in Absinthe is very low because of the way the spirit is made, and nowadays there are rules about what percentage of thujole is allowed. People have studied old bottles of the stuff too, and it wasn’t found to be super-thujolated. It was very popular with poets and artists; they said the green fairy helped them be more creative.

More creative, or more deadly? One tale tells of a man who killed his family in 1906 and claimed Absinthe drove him crazy. He was actually excessively drunk from a number of drinks, and was found guilty. After this and the subsequent public outcry, Absinthe was prohibited in Switzerland. France and the USA followed suit. Nonetheless, it’s the remarkably high alcohol content in Absinthe that makes it a dangerous drink, you’d definitely die from alcohol poisoning before dying from Wormwood poisoning.

The scariest story by far is the one in Eurotrip where a guy makes out with his sister after an Absinthe bender. “Dude, you kissed your sister!” That’s way worse then killing your family!

So by all means, if you like Absinthe (I’m not a fan) then drink it, but any mind-alterations are probably just your imagination. You’re supposed to mix it with water to let the flavours come out. Has anyone actually done this? Apparently it makes the clear green liquid go cloudy, because the essential oils are not soluble in water. Now that’s science.

Spoons Will Kill You

// January 6th, 2010 // 3 Comments » // Recent Research, Science Communication, Science at Home, Unethics

The deadly spoon, it makes a knife look tame by comparison. Indeed, only a meat cleaver attached to a hand beater is more dangerous.

Being a lover of spoons (not literally thank you very much. I’m just fond of them, okay? Nothing wrong with that) I am skeptical of this research which suggests that spoon dosing of medication is a major health risk. Yes sir, skeptical I am. This is the first time I’ve disagreed openly with research, so here’s hoping it doesn’t bite me in the ass like my last parrot did.

So I found this story in Science Daily today – “Can Kitchen Spoons Be Dangerous Spoons? Too Little or Too Much Medicine, Depending on Spoon Size” which takes you through to this press release and this swanky picture

Made by this swanky photographer.

With a shoot like this, you know you’re onto some quality research, and oh yes, it’s been picked up by several news sources. To quote the press release (as so many of these news articles did) using kitchen spoons to measure liquid medication tends to lead to significantly over- or underdosing “beneath the point of effectiveness” according to Dr. Wansick.

Here’s the method they used: They took 195 university students, and asked them to measure out a teaspoon of cough medicine into three spoons in order: 1. A teaspoon. 2. A medium sized tablespoon. 3. A large spoon. Then the researchers measured how much liquid they poured. The conclusion: In the medium spoon they underestimated by 8%, in the large spoon they overestimated by 11%. Over time this could add up to an overdose.

Why I think it’s crap
In the paper and especially the press release they say this is an important health risk. Is it? The first line of their report says that “spoon dosing has been identified as 1 of the 3 major causes of dosing errors and pediatric poisonings,” but when you read the report they’re referencing, it says the cause is people giving a child a whole tablespoon worth of medicine rather than a teaspoon (because of the confusing tsp / tbsp shorthand.) It’s not parents taking a tablespoon and try to measure out a teaspoon of medicine in it!

Who in their right mind would do that anyway? Why not just use a teaspoon, particularly if giving it to a child? Is the “I’ll measure it sort-of teaspoonish that’s close enough” thing a common issue in poisonings? Not according to the paper they reference in that first line. How many people use teaspoons to measure medicine nowadays? The report doesn’t say.

All this paper concludes is that people are crap at estimating how much a teaspoon of liquid is when they use a tablespoon to measure it. Big whoop.

What I have a problem is, is how they’ve marketed it with a press release and a photo shoot to say that spoons are dangerous, based on no clear evidence to suggest this is a real health threat as there’s nothing to say PEOPLE ARE EVEN DOING IT let alone getting sick from it!

This crappy example of science communication made me snap my peg leg in half. Now I’m going to eat a bowl of jelly to console myself, and I’ll enjoy every damn spoonful.

Oven baked pizza that gets you baked!

// December 17th, 2009 // No Comments » // Drugs, Just for Fun

Dude this pizza has weed in it

You’d expect it in Amsterdam, but now the trend has reached America. Pizza, lasagna, cheesecake with a good helping of weed. It’s not illegal if it’s medical!

It’s a medical marijuana dispensary slash eatery called Ganja Gourmet, and it just opened in Denver. You need a card from a doctor to buy the food, as written on the tie-dyed shirts of employees “Our food is so great, you need a license to eat it!!!” On the other hand, 90% of the food has been take away for the first week, so how well are they controlling that? According to this, the council is considering making eating or smoking cannabis on site illegal – so take away only. Isn’t that only going to make it worse?

Aside from possible issues in dosage control I think this is a great idea, particularly for people with cancer who feel nauseas and have trouble eating. Plus where does it say we have to take all the fun out of medicine? Do we have to grind everything up into a flavourless pill for maximum un-enjoyment? The health benefits of having fun, laughing and sharing a meal shouldn’t be underestimated, think of clown doctors! And with all the crappy drugs and hospital stays and radiation and chemo and hairloss and all that goes with cancer treatment, they SHOULD get a special pass to a groovy cafe where they can take drugs no one else is allowed to take. There has to be some silver lining!

So take away or dine in, you can have your high and eat it too.

Hat tip to Dr_Leigh on Twitter. Picture from somewhere in Cambodia, not connected to Ganja Gourmet. Apparently they’ve been doing the special topping for a while now!

A recipe for eggnog, and notes on the spice-drug nutmeg

// November 30th, 2009 // 2 Comments » // Drugs, Just for Fun, Science at Home

Eggnog

Arr, it be that time of the year when all the good cabin boys hang their stockings off the mainsail and cook gets busy making eggnog.

My harbour is in Australia, so eggnog is not a favourite of mine. The rich, milkiness of the drink is ill-suited for the hot Yuletides we experience, and a glass of ice-cold fermented grape is better suited for the clime.

All the same, eggnog is TRADITION, and is a particularly piratey tradition when you make it with RUM! Here be a recipe for the delicious December drink, made piratey by your Captain but sourced from yon landlubber website.

6 eggs (parrot)
2.5 cups whipping cream
2 cups whole milk (powdered variety easiest for storage)
1 cup caster sugar
0.5 cup dark rum
0.5 cup brandy (substitute with more rum if you can)
0.5 teaspoon vanilla extract
0.5 teaspoon nutmeg, freshly grated

Beat the eggs until frothy (the eggs, not your mouth), add sugar and beat, sprinkle in nutmeg and vanilla and beat, add in the whipped cream slowly while beating, add the grog and beat. Chill for an hour belowdecks and serve cold to your shipmates.

Beating is the best way to mix ingredients as it lets out your inner anger and anguish which otherwise may turn rancid and make you bitter inside. If Ahab had made eggnog during his voyage on the Pequod it is likely that the events leading to his death would never have occurred, and he would be living to this day a happy one-legged individual. Beating also gives you most excellent biceps that will strike fear into the hearts of your enemies.

Ye may notice a certain buzz upon drinking your concoction, which ye may blame on the rum (you DID add extra rum, right? Don’t stop at a measly half a cup.) Well ye are most likely right, but all the same, did ye know nutmeg can be a drug? That’s right, melange is not the only spice-drug. Nutmeg be a creepy looking thing, a seed wrapped tightly by bright red tentacles of another spice called mace.

Nutmeg and Mace

Nutmeg is in certain doses hallucinogenic. The effects, by all accounts, are not enjoyable. You see, nutmeg contains myristicin, which is a weak monoamine oxidase inhibitor – you may be familiar with that term as a class of antidepressant. In high doses (of a couple of tablespoons) nutmeg can cause hallucinations and euphoria, but before you go reaching for that spice rack let me tell you of the side-effects, including nausea, bloodshot eyes, dry mouth, anxiety, convulsions and palpitations. Plus it kicks in after three hours (making it a likely candidate for a this-isn’t-working-try-more overdose) and lasts for about five hours. Plus the bragging rights are non-existent. “Oh dude, I did like two tablespoons of nutmeg this weekend!” HARDCORE!

All things considered, I’ll be sticking to my rum-filled eggnog, and adding spice-drug just for flavour. This one’s to yer health.

Mac for 3D Molecular Visualisation. Apple makes Drug Design Sexy

// November 23rd, 2009 // 3 Comments » // Drugs, How Things Work

Drug design seems a glamorous industry full of coloured liquids, crystal bottles and incredibly expensive machines, but the reality involves a lot of repetitive experimentation and number crunching. Taking a lot of data and making it something you can imagine and understand is a freaking hard thing to do! Mac has made it easier (oh mac, how I love thee *hugs*) with sexy 3D visualisations for drug design.

scientist drawing molecule structure

Oh for the days when we could take a natural product and improve it by trial and error! Okay, we still do it a bit, but the trend at the moment is for a premeditated plan of attack – you need to track down active areas on target molecules and imagine a molecule that will fit in the active area, and then find out a way to make that molecule. It’s aptly called rational drug design, computer-assisted drug design or computer-assisted molecular design (CADD and CAMD).

Rational drug design is taking something that works a little bit and creating something else that works better. Identifying that initial “lead” molecule can be done by either using the natural product in the body (if it is known), studying cultural leads (old wives tales often have some truth to them), or by running a big ol’ experiment with a massive library of drugs. OH YEAH!

So we take the lead molecule and find out how well it binds to the molecule to make a benchmark. Then we change it. Add in a bit more positive charge on one end might make it stick better to a negative pocket in the active site. Adding a bit of bulk will make it fit nice and tight, less likely to fall out but if you make it too big then it won’t fit at all. Maybe your active site has two pockets and they need to be linked together a certain distance apart. This is where good old experimenting comes in, and each new trial reveals a little more about how the active site binds to a drug.

Following the molecules down the rabbit hole like this is called QSAR – quantitative structure-activity relationships – measuring the level of activity the drug has (or how well it binds to the target) against changes in structure. In the end we make a fancy-pants equation and use that to create the most effective drug POSSIBLE TO MAN with the least amount of side effects. It takes a long time, but the results include many of the drugs on the market today.

But what about 3D technology?

Imagine the time you can save by having a picture of the active site already! Rather than run hundreds of different drugs for your QSAR, you can pretty much paint a molecule in and try a few variations. By actually having that picture in front of us we can design drugs much more effectively, targeting them to the areas we already know are there. Plus it looks HOT. Check out Tamiflu.

Tamiflu Tamiflu

You can click on it and open up a 3D structure that you can rotate and zoom in on.

3D small molecules aren’t exactly new, but big-ass complex proteins are harder! I know of two journals that are using interactive 3D images of molecular structures: The journal of Biological Chemistry and PloS ONE are using software called iSee to make models of proteins and small molecules that you can move around and zoom in on. The Structural Genomics Consortium (SGC) are a non-for-profit organisation who are creating 3D structures of proteins and releasing them into the public domain for unrestricted use. It’s like open-source science! Having a ready-made starting point like this opens up a massive chunk of lab time and budget, and it’s for freeeeeee! You can download it for freeeeeee here, and have a look at their library. These pictures have come from 3dchem.com which is easy-peasy if you just want to click and enjoy.

The only thing cooler than 3D molecules are 3D molecules that actually look like they’re jumping out the screen at you, like the amazing graphics of Coraline or Up (seriously, 3D movies are way cooler than I remember them! I remember those dodgy red and blue glasses, and thinking that was the best thing since ships biscuits even though it gave me a headache. These movies kick those old ones ASSES!) Seeing a molecule in true 3D is even more amazing, and it’s easier to see all the details. We did it once or twice at Uni in a special mini-cinema they had set up, I think to help people find the best place to drill for oil (under the X, duh). It was awesome seeing all the little enzymes supersized! If you’ve got some of those 3D glasses lying around, check Tamiflu out now! Guess those red and blue glasses were good for something after all!

Tamiflu in 3D

My boyfriend SexyMan blogged about all this here on his site Emerging 3D, albeit sans the science. What he does have is details on how to trick out a mac so it can do stereoscopic 3D and a link to some Mac scientific software. Mac’s are sexy enough, but a tricked out 3D displaying new iMac with the cool new touch-mouse? My mouth is watering just THINKING about it!

Why I am Anti Antibacterials

// November 15th, 2009 // 5 Comments » // How Things Work

Work just bought three lovely new bottles of antibacterial soap. Bummer. One of my very first posts was about how much antibacterial EVERYTHING there is nowadays, and how it will unleash a race of superbugs onto us all, causing the apocalypse.

I’ve settled down a little now, because I went to a talk with a microbiologist (at the RiAus – see my previous post) and asked him what he thought about antibacterials, and he said they were unlikely to cause multiresistant bacteria because it mostly happens in hospitals, where a lot of sick people on a lot of different drugs are crammed together and cross-infect each other (yummy). I still think antibacterials are only helping select the most resilient bacteria out there by giving them an advantage over the weaker bacteria, but he’s probably right about the multiresistant thing.

Anyway, antibacterials are bad for reasons other than creating resistant bacteria. Which I talk about in this video I made to raise awareness, and for funzies :)

Why I am Anti Antibacterials from Captain Skellett on Vimeo.

There were a couple of other things he said which I thought were fantastic. Like that biology is not an exact science. Physics can calculate how to get to the moon, and it will work everytime (excluding Apollo 11 of course) because the moon doesn’t dodge. Bacteria do. With antibacterials we’ve created an environment where evolution steps in and resistance can develop. It’s particularly bad because drug discovery takes about 10 years to take a drug from conception to sale, and bacteria evolve a lot faster than that.

Also, you know how you have e-coli naturally in your gut which help you digest food (I distinctly remember my microbiology teacher telling us that poop was just e-coli with a little bit of colour.) Did you ever wonder where they came from? When you’re born you are e-coli free, the womb is a very sterile environment, but somewhere along the line in the first few weeks you get a whole colony of e-coli. You don’t usually hear people discussing babies, mothers and feces, but that’s the gist of it…

Rejuvenated hopes for an anti-aging pill

// July 9th, 2009 // 2 Comments » // Recent Research

Meet rapamycin, our latest hope for the fountain of youth.

Rapamycin

Check out all those chiral centers, it’s freaking cyclical and everything!!! Can you BELIEVE it???

As published in Nature, the experiment went thusly: Researchers fed rapamycin to 20 month old mice (they were going to start earlier, but had apparently had some issues) and found that they lived much longer than the controls – 14% longer for females and 9% for males. This probably means Jack to you, so let me put it in human terms.

The treatment started when the mice were the equivalent of 60 years old, and it added an average of 13 years to their life. In the words of yon media release “this would be greater than the predicted increase in extra years of life if cancer and heart disease were both cured and prevented.” Wowzers. You couldn’t make that sound more dramatic if you TRIED!!!

As you would expect for something that looks so intricate, it’s made by a microbe. In this case, by a soil-dwelling bacteria called Streptomyces hygroscopicus. It is also known as sirolimus, and was first discovered on Easter Island in stunning want-to-go-there Polynesia.

Yeah, I think I'll do my research here...

The study of aging is called gerontology, and I was interested to read that one method to slow down the aging process is caloric restriction. Eat less, live longer. Now I feel bad about the giant bowl of pasta I had for dinner. Delicious though it may have been, was it really worth a week of my life?

Rapamycin inhibits cell division and the functionality of certain T-cells, and as such is used as an immunosuppressant to prevent post-transplant organ rejection, and is considered a potential chemotherapy agent. It’s also an antifungal. Interested in chemical synthesis? Who isn’t! Check it out here, yet another shameless Wikipedia plug brought to you by Captain Skellett :)

Now before we all get overexcited and start racing for old age, remember that mice are not little people! There are plenty of biological difference between people and mice, and the success of this trial does not mean that the road to a therapeutic will be easy. In fact, seeing as it’s currently being used as an immunosuppressant, it would actually be dangerous. That said, to quote Randy Strong, (love the name) Ph.D. “we believe this is the first convincing evidence that the aging process can be slowed and lifespan can be extended by a drug therapy starting at an advanced age,” and it represents a big-ass milestone on the road, rocky though it might be.
