For someone who has been blogging since high school, I was actually thrilled when our Clinical Chemistry professor told us that EduBlogging will be one of our requirements. I was excited since I really love customizing and doing blog-related stuff…in my case, it’s like doing something you love and earning points for it. But then, it hit me. I realized that I have never blogged anything about endocrinology, toxicology, or anything related to my future profession in my 5 years of blogging. As soon as I thought of this, I knew I won’t do well.

And as I was doing my first post, I realized that this is very much different from the usual blogging which I’m used to doing. But since it’s a REQUIREMENT, I needed to do it. And so I was one of the last people who posts one minute before the deadline. Yes, I’m exaggerating. But the point is, it suddenly became something new for me. But that didn’t stop me. I took it seriously and unexpectedly, I learned a lot from it. With that being said, I’d like to share a few NEW things I learned and did in EduBlogging, which makes it different from my usual personal blogging:

EduBlogging is not just about writing what you feel or what you want. It’s not about writing what you did throughout the day… it’s about writing what you’ve LEARNED. You can’t just post whatever you want. You need to listen, read, and read more to be able to do a blog post. Unlike personal blogs, one post takes lots of reading and listening to be able to make one. As they say, patience is a virtue. You need patience to be able to do a single post. You need to be careful not to give out wrong information.

Yes, thick. EduBlogging is based on books, journals, and what we learn inside the classroom. We don’t base our posts what we want to write, or what other people want On my personal blog, I express myself freely on how I actually act in reality. People are different… in actions, in words, and in interests. There may be people who would agree with you, and there will always be someone who would disagree. There are no right or wrong posts; it’s just that you can’t please everybody… that’s for personal blogs. But in EduBlogging, there ARE wrong posts. You can’t just post any information that you, yourself, are not sure of.  If so, you might end up giving the wrong information to other people. We need references for this. It’s not what you think is right. It’s WHAT IS RIGHT. It’s not exactly about pleasing everybody, though. It’s about giving the right information to everybody.

Reblogging is not a crime, but plagiarism is. Unlike on other blog types where you are free to reblog and post photos, videos, and quotes, you can’t just put anything on your blog which is originally from another blog. Come to think of it, even personal blogs give credit to the owners. No, you can’t just copy something and paste it on your blog. Admit it, we don’t really learn anything for the “copy-paste” thing. EduBlogging is about learning. Not just for the readers, but for the writers, too. What’s the sense of the “Edu” in Edublogging if you don’t learn anything from it… even the basic rule “DO NOT COPY”?

. In my personal blog, a photo post without a caption is enough to show what I love or what I did. And there are actually people who are after the images, not on words. And long paragraphs might just scare them away. But in EduBlogging, there will always be a deeper meaning behind every photo you include in your post. Explanation is the key. And it’s okay to have a long one. As long as you give much information as your readers will need. You wouldn’t want to confuse your readers on why that certain photo is included in your post. Share everything you know. As long as it’s right, of course.

If you’re doing an EduBlog without having fun reading, browsing and thinking of ways on how to make your post interesting and informative at the same time, might as well give it up. This might be one of the few similarities on why bloggers blog. It’s about having fun and making your readers satisfied and happy when they read your posts. And when you do, good information, great feedbacks, good grades, and incentives will come along.

I have always considered my personal blog, scarletpotion, as my masterpiece. But ccblognotebyfaith, for me, is an achievement and is something that I can be proud of. It helped me learn not just things about endocrinology and toxicology, but also about formal writing, and giving out good information. EduBlogging is definitely BLOGGING... WITH A TWIST!

To our professor who encouraged us to do this, you always tell us to keep it up. But now, let me be the one to say this, KEEP IT UP, MA’AM. You have taught us a lot with this activity… not just about Clinical Chemistry, but also how we need patience, understanding and perseverance. THANK YOU. J

TOXICOLOGY: A Taste of Poison Paradise

For students, the word TOXIC is not unfamiliar. Not just because of Britney’s famous song, but it’s also because this is what we say whenever we’re stressed out by all those schoolworks. I, myself, am guilty of saying this too often. And I am pretty sure that you have told this to someone, or someone had told you this before because of stress. With that, this made me curious. Why do we always relate this word to stress? What’s the actual meaning of this? Let’s take a quick glance on Toxicology in order to answer all those bugging questions in our minds. 


Toxicology is the study of the adverse effects of chemicals, drugs, food and beverage additives on humans, its symptoms, mechanisms, detection and treatment of poisoning. Poisoning may occur when a substance is introduced to a human body which causes death or injury.

Toxicologists focus on the adverse effects of these chemicals which may be referred to as:

  • Toxins—toxic chemicals which are produced within living organisms(e.g. Hemotoxin)
  • Toxicants—toxic chemicals which are made by humans and introduced to the environment(e.g. pesticides)
  • Poison—toxicants that may cause death or injury when taken in small amounts.

The LD50 is used to determine that kills half of the animals tested. This is a standard measure used to compare the toxicity of chemicals.


Toxicokinetics is the study of how the body handles poisons. This is composed of four processes:

Toxicodynamics, on the other hand, focuses on what poisons may do to the body. Poisons may give different effects to the body:

  • Acute Effects—these are short term consequences of exposure to the body.
  • Chonic Effects—these relate to much longer time

The higher the exposure to certain substances, the worse it could affect the body.


Prevention may be done by practicing good occupational hygiene, in which one controls and evaluates health hazards in the working environment in order to protect the worker and the community.
For the treatment, one can do/take any of the following:

  • Decontamination—when exposedphysically, one can do decontamintation through eye washes or showers
  • Antidotes—these are procedures or medications given to counteract the poison
  • Emetics—these could only be administered to conscious patients, and never in cases where corrosives are involved

Definitely, all of us had a taste of poison paradise. Good thing “stress” is the only poison we experience. That’s one thing we should be thankful of! With knowledge and information, we can avoid exposure to other toxic substances. So let’s be cautious and learn how to take care of ourselves and other people.

Thanks for reading! Tune in for other TOXIC topics! :)

The Endocrine System: A Messenger

Whenever we experience changes in our body, mood swings or other things which are quite hard to explain, it's impossible not to hear this one familiar word: HORMONES. Does it explain everything? Does it make us understand why these things happen? We must admit, it actually gives us more questions in mind. To learn more about HORMONES, we need to know more about Endocrinology. 


The word endocrine comes from two Greeks words: endo which means "within" and krino which means "to separate". This means that chemical signals are produced within and secreted from the endocrine glands. The endocrine system is responsible for the production and secretion of hormones which would release chemical signals into the circulatory system to carry these signals to the different parts of the body, affecting one or more organs.With this, theSome of the main functions of the endocrine system include:
  • Regulation of water balance. The endocrine system makes this possible by controlling the solute concentration of the blood.
  • Regulation of uterine contractions during delivery of a newborn and stimulation of milk release from the breasts of a lactating mother.
  • Regulation of growth of many tissues, metabolism and tissue maturation. The endocrine system regulates the growth of different tissues such as bone and muscle tissues. The endocrine system also influences the maturation of tissues resulting in the development of adult features and behavior.
  • Regulation of Na+, K+ and Ca+ concentrations in the blood. With this said, the endocrine system helps in ion regulation.
  • Regulation of heart rate, blood pressure and blood glucose. 
  • Immune system regulation. The production and functions of the immune cells are also controlled by the endocrine system.
  • Control of reproductive functions. The endocrine system also controls the reproductive functions of both males and females.

The word hormone is derived from the Greek word hormon, meaning "set into motion", and hormones "set responses by cells into motion". Hormones are the fluids produced by endocrine glands These are the "messengers" which will travel in the circulatory system to send signals to the different parts of the body. Hormones may be classified by chemical structure into three classes: (1) steroid hormones, (2) amino acid derivatives, and (3) peptide hormones.

Glands are responsible for producing and storing fluids which the body needs; but the endocrine glands are not like other glands in the body, since they have no tubes where their secretions would flow through, and thus they are called ductless glands.  Without these tubes, endocrine glands will directly secrete the fluids(hormones) to the circulatory system, to be able to send signals to the different parts of the body.

The major endocrine glands found in the body are the pituitary gland, hypothalamus, thyroid glands, parathyroids, adrenals, pineal bodies, and the ovaries and testes.
