Ter bepaling van de vitamin B12 voorziening

De verhoogde detectie van methylmalonzuur in de urine vormt een indirecte marker van een vitamine B12-defici�ntie. Het maakt het mogelijk om conclusies te trekken over het metabool beschikbare vitamine B12. Vitamine B12 fungeert als een co-enzym van methylmalonyl-CoA mutase die in de citroenzuurcyclus methylmalonyl-CoA katalyseert tot succinyl-CoA. Wanneer deze stofwisselingsroute bijv. ten gevolge van een verminderd aanbod van vitamine B12 verstoord is treed een verhoogde excretie van methylmalonzuur op.

De bepaling van methylmalonzuur in de urine is te verkiezen boven de bepaling in het serum: het is eenvoudiger en gevoeliger. De diagnostische waarde van de parameters in serum wordt vaak beperkt doordat vitaminen in het serum gebonden zijn aan bindingseiwitten waardoor de vitamine B12-verzorging op cellulair niveau niet altijd voldoende kan worden bepaald.

Veelvoorkomende oorzaken van een vitamine B12-tekort zijn gastro-intestinale aandoeningen chronische atrofische gastritis en misbruik van alcohol en/of� medicijnen. De gevolgen van het gebrek uiten zich met name in stoornissen in de erytropo�se (megaloblastaire anemie) glossitis gastritis obstipatie en in neurodegeneratieve en psychiatrische symptomen (neuropathie dementie geheugenstoornissen en psychosen).

De uitslagen dienen als basis voor een individuele therapie en moeten met een arts of therapeut worden besproken.

Indicaties:
- bij het vermoeden van een vitamine B12 tekort

Quality product for the right dog...
Color: Orange
Honestly it's a really cool product well constructed and moves around on its own with several different modes. The design id brilliant with a tough rubber ball that unscrew to expose the element that makes it move in the middle. The dog won't be able to unscrew it but you can if you ever need to replace the ball for any reason but it would take some work for a dog to destroy the outer ball. Almost like "Kong" type material. The ball is about the size of a softball and the element inside is about the size of a golf ball. I thought my dog would love this but she was afraid of it, which is strange because she's afraid of nothing. Anyways I gave it to my neighbor upstairs and she has a yorkshire terrier who plays with it all the time so it all worked out great. Quality product . Good job!

Thought it was a good idea but not for my dog
Color: Blue
Seemed great but my dog continued to bark at it. Finally she hid it and I haven’t looked for it.

Durability
Color: Blue, Color: Blue
won’t give this product 1 star because my dog still had a good time with it for a few hours. After opening and preparing it, I gave it to my dog and it definitely caught his interest. However, when he chewed on it, plastic pieces started breaking off and he began swallowing them. This product is definitely not suitable for aggressive chewers.

Winner !!!
Color: Orange
This amazed us. For perspective, we're talking about a three year old white german shepherd who if he's in the mood, has and can kill a toy within minutes or oddly enough be gentle with furry balls and carry them around as if they are his babies. He's an odd duck. Anyway, since he was a pup, and to this day, he'll play and entertain himself, he'll grab a ball, throw it up in the air, then pounce on it as if it's from outer space. It's really quite cute and funny. Because of those two things I was looking for something interactive that would entertain him and confuse him....let's be honest, watching a confused dog is one of life's great pleasures. I tried two other interactive balls and they were crushed immediately. After reading a lot of reviews, people with german shepherds said this ball actually had a life span. I thought the third time could be the charm and ordered one. Well, I think it actually may be from outer space because he's obsessed with it and hasn't taken a bite out of it. He hasn't once chewed it or even teared little pieces off. The three settings are great. Sometimes he likes one better than another, then forgets about the others. I'll change it up to one he hasn't seen in a while and the whole game starts over again. He'll throw it up in the air as he does with his others, watch it and try to figure out which way it's going to go. And yes, he will pounce on it if he times it right. The size is perfect, it's heavier than your average ball but, that's what make it sturdy. I have to sneak it away when he isn't paying attention to charge it, otherwise he'll sit, stare and cry if he knows it's on the counter charging. It's a lot of fun for all of us. I'm so happy I bought it...... I say give this ball a chance even if you have a beast with killer instincts. I'm buying another for a friends 2 year old golden retriever granddog. Thank you Cheerble.

Perfect Size for Tiny Dogs
Style: 14" Length Sport Launcher, Style: 14" Length Sport Launcher
Excellent size for tiny dogs who can only manage the tiny tennis balls. The launcher is easy to use, even for my 8 year old. It’s pretty much revolutionized ball time for the dogs and the kids - they actually like taking him out to play fetch now. It’s super light but still lets you toss the balls a lot farther than just throwing it. Great value for your money and it’s helps strong for weeks of repeated used, super durable.
