uses of leeches in microsurgery?
101569
They have been using leeches for their medicial properties for thousands of years. When they latch onto the affected tissue they produce a situation that is much like regular venous circulation in that area.  They secrete an anticoagulant that keeps the blood from clotting as well as a local vasodilator that opens up the vessels in the affected area.  Most hospital pharmacies carry a bucket of leaches for use in surgery's and they are even billed to the patient through the pharmacy just like other drugs they receive.

Yeah, it's called a scalpel.  Seriously, though, you should talk to your doctor about it.

First we have to understand why leeches need blood to survive.  Blood is made up of rich proteins and lipids that allow a leech to live quite well.  Second, we need to understand the mechanism by which leeches are attracted to their "prey" Basically, all mammals (both warm and cold blooded) are privy to leech attachment.  It has been widely discussed that the exact attraction of leeches to a mammal involves secretion of pheromones and other biological chemicals that a leech's detectors will recognize.  Since other leeches don't secrete these biological chemicals, they are safe from "attack".

That's a great question!\n\nMy first thought was No, but I googled and found a great piece on worm hearts (see link below).\n\nIt turns out they have something that does a similar job, but is not a heart like we mammals have. Follow the link below for all the details.

Ask a specialist or a person whose job is to do such things.\nSorry, but I do not believe anyone here can be precise.

I work for a LASIK and cataract surgeon so I feel I can give you some advise.  \n\nThe majority of complications associated with LASIK surgery involve the process of making the flap on the cornea.  In LASIK there are two main methods for making the flap.  One is with a devise called a microkeratome, which is basically a blade that is used to cut a flap in the cornea. The other devise is a femtosecond laser called Intralase that is used to make a flap.\n\nIt is proven that the Intralase system greatly reduses the accuracy of making the flap and the chances of any significant complications with the surgery.\n\nSo the main thing that I would recommend is going with a doctor that uses Intralase rather then a microkeratome.  You should be able to find a doctor doing this in most major metropolitan areas.\n\nAnd also don't settle for the bargain basement LASIK centers.  In life, you get what you pay for.  And do you really want to buy a surgery that's on sale?\n\nWell good luck on your decision.  LASIK is definately not for everyone, but it is amazing for those that qualify for it!

I have had one removed with lazers. They numb up the area first then they cut it out with lazers. My wound bled badly and the wart is comming back. Just so you know a wart is a defect in the immune system thats what causes them. Your daughter might have them for the rest of her life. But she is young so her immune systme might take care of the problem eventually. I wouldn't recomed the sugery unless the wart is very large and noticable it is very painful about a day after the sugery. Hope this helps you make a decision.

Neosporin and a band aid.

In the lab we used to enlarge the hole on micropipette tips when pipetting things like glycerol. Just cut off a little bit of the tip with a razor blade. With samples over 1 mL we were just patient because the plastic disposable pipettes tend to shatter if you try to trim them a little.

***\n\nThere are two types of Cataract Surgeries...\n\nPhacoemulsification (Also called small incision cataract surgery.) - This, most common, type of cataract removal procedure involves the surgeon making a small incision on the side of the cornea - the clear, dome-shaped surface that covers the front of the eye - where a tiny probe emits ultrasound waves to soften and break up the cloudy center of the lens. The cataract is then removed by suction through the same incision. \n\nExtracapsular surgery - During this procedure, a longer incision is made on the side of the cornea to remove the hard center of the lens; the remainder of the lens is then removed by suction. \n\n***\n\nThe best way to remove the cataract is through surgery. This is how it is performed...\n\nAfter drops are used to numb the eye, a small, less than 3mm, incision is made. Special microsurgical instruments are used to break up and suction the lens fragments from the eye (phacoemulsification). The back portion of the lens capsule is left in place and polished for clarity. A small foldable intraocular lens will be inserted through the wound and unfolded in place of the natural lens. The incision is self-sealing so that no stitches are needed.\n\n***\n\nCheck out these links too...\n\nhttp://www.healthsystem.virginia.edu/uvahealth/adult_eye/cataract.cfm\nhttp://www.southeasterneyecenter.com/info/catfaq.htm\nhttp://www.lasersurgeryforeyes.com/cataractsurgery.html\nhttp://www.nei.nih.gov/health/cataract/cataract_facts.asp\n\n***

It depends on how big of a mess you make of the 'surgical site'...and congrats on having the temerity to pull that sucker out yourself! \nSterilize the tweezers (use rubbing alcohol), sterilize the area (rubbing alcohol) and sometimes it helps to numb it first with an ice cube (then clean the area). After you've pulled that bad boy out, dab it with hydrogen peroxide, then put some neosporin on it and a small bandage for a day. \nYou should be OK in a few days.

It's fine to try these things, they won't do any damage to the urinary tract. It's worth noting that excessive use of a vib-rator can cause the clitoris to become desensitised though, so while they're fun to use now and then, it's best not to rely on them solely. As for the water in the bath or from the shower head......wow........that's all I can say!

Sounds like you had lazer eye surgery. Yes,No?  If so go get some more ASAP. You need them to help with the healing process. Get some more.

A regular lens microscope can be used. The kind you just might find in a school classroom.\n\nI don't think Har Mites are that small.\n\nYes, I believe Hair Mites move.\n\nI do not have much knowledge of hair mites and therefore, my answers are not completely doubt-less.

You should first use a torniquette upon the area you need to do the cannulation.After engorgement of veins beneath your torniquette and after using antiseptic solutions for cleaning the skin area you have to use an angiocath introducing to your vein , when pushing in piercing the skin in the direction of vein with almost 15 degree slope, you will see blood in the hub , in this time stop going in and hold the metal part firmly and push the plastic part in .then fix the angiocath .\nI think using this way you can successfully perform what you asked.\ngood luck.

Sure there is\nBotulinum toxin injection is one of the best local treatment for this condition\nI'm a neurosurgeon and I manage a lot of cases with excellent results

Not a doctor... but there is a product by Genzyme Corp that is called seprafilm.  They use it in abdominal and other surgeries to prevent adhesions.
