Save lives Donate Blood

Everyday, thousands of people undergoing major surgeries need blood transfusion. Many people suffering from various conditions like haemophilia (genetic disease that impair the body’s ability to control blood clotting), dengue, severe anaemia, blood cancer, thalaessemia need blood transfusion.

On an average, 3 to 3.5 lakh bags of blood are needed in our country every year. There is always strict advice to transfuse safe blood. But from where these amount of blood will come? Blood is not produced in a factory and yet there is no alternative source for blood. The only source of blood is human body.

Usually, blood from relative is encouraged for transfusion. But if a healthy relative of the same blood group is not available, blood from any healthy voluntary donor of that group may be transfused. In our country, people usually depend on the organisations like Sandhani, Redcresent, Badhon, Quantam etc. for safe and fresh blood. We should remember that these organisations or institutions do not manufacture blood. They are only the media to collect blood from healthy voluntary donors to provide it to the needy people. The more the voluntary donor, the more these organisations will make blood available.

Here the question comes — who can donate blood? Any person within the age group of 18-60 years with a body weight as minimum 45 kg for female and 48 kg for male and having a general well-health is an eligible blood donor. Healthy means that you feel well and can perform normal activities; your blood pressure, pulse, body temperature are normal; and you are free from any blood boarn diseases such as malaria, syphilis, gonorrhoea, hepatitis B, C, AIDS, haemophilia etc.

You may have chronic conditions like diabetes or high blood pressure; but in these cases, healthy means — you are being treated and the condition is under control. Such healthy people can donate one bag (350-450 ml) blood safely every 4 months.

After donating blood, the donor should take rest for 15-20 minutes. Routine work is absolutely fine after the initial rest. Rigorous physical work should be avoided for few hours. After resting for a while a donor should be given some liquid (fluid) to drink, such as water, ORS, milk or fruit juice. The donor needs no special diet other than a routine balanced diet. The body replaces blood volume or plasma within 24 hours.

It is very unfortunate that voluntary blood donation is still not so popular in our country. This is due to the lack of proper awareness, social movement, irrational fear and superstitions about donating blood. Some organisations are working in this field but still the number of voluntary blood donor is not keeping pace with the yearly requirement of blood.

In a study conducted by Sandhani, Dhaka Medical College Unit, it was seen that 62 percent of the population were unaware of the blood-transmitted diseases, 53 percent of people did not even know what their blood group was; 66 percent admitted that their knowledge about blood donation was not sufficient.

For the lack of adequate voluntary donors, many patients are being compelled to buy blood from professional blood donors. Such donors are more likely to carry dangerous infections and their blood is more likely to be of lower standard, as they tend to donate, better to say, trade more frequently.

In Bangladesh, mostly drug addicts sell their blood to get money to buy drugs for addiction. Usually they are under-nourished, having less haemoglobin in their blood. They also suffer from various blood transmissible diseases. So, the patient who is getting that blood, though initially may be benefited, is in risk of having many diseases.

In a research conducted in our country, 22 percent of the professional donor was found having Syphilis and 29 percent having Hepatitis-B. A study conducted in BSMMU showed that 60.1 percent of the patients suffered from hepatitis, who got transmitted unscreened blood from professional donors.

Again, many patients fail to get any kind of blood, not from voluntary donors, not from professional donors even. Voluntary donors’ safe blood and professionals’ unsafe blood collectively fail to fulfill the yearly requirements of Bangladesh.

If only 1% of the population donate blood once a year (though a healthy donor can donate blood 3 times a year safely), the yearly collection stands a satisfactory number which may fulfil the requirement smoothly.

Mathematically it is an easy task but it does not happen in reality. We all need come forward to save thousands of lives dying due to the shortage of blood.

Green Tea is Related to Reductions in Body Fat

Time has come to say, few cups a day — keep the doctor away. I am talking about green tea.

It is produced from the leaves of Camellia Sinensis by some special processes. High in vitamins, minerals, anti-oxidants and a whole swing of anti-aging and cancer fighting compounds, green tea is great. It is wildly being used as a significant part of a healthy diet.

Antioxidants are an important factor in achieving finest health. An antioxidant known as Epigallocatechin Gallate (EGCG) is at least 100 times more effective than vitamin C and 25 times more effective than vitamin E at protecting cells from harmful influence.

Ancient Chinese people have always used it for medical purposes and it is a part of Chinese history. In Japanese tradition, learned scholars wrote whole volumes on the importance of green tea.

Recent studies show that green tea restrains the spread of disease. It has a variety of antibacterial and antiviral properties. It is good to fight against cold to food poisoning. It is good for oral hygiene as it destroys bacteria that cause plaque and bad breath. It closes main receptors that produce allergic reactions.

Studies show that drinking green tea is related to reductions in body fat. According to one Study, green tea can burn 35-43 per cent more fat during the day when one drinks 3-5 cups.

The University of Chicago’s Tang Center for Herbal Medical study shows that it reduces the fat deposits under the skin and in our belly area. Researchers found that Green tea prevents one from gaining weight by stopping the movement of sugar into body’s fat cells and also burns fat by increasing body metabolism.

The International Journal of Obesity states that green tea contains polyphenols which causes body to produce heat that burn body fat. Several polyphenols also keep cancer cells from gaining a foothold in the body. Study after study has found that drinking regular green tea can decrease the risk of breast, stomach, esophagus, colon, and/or prostate cancer. Some green tea studies prove that it lowers blood sugar.

Green tea is involved in reducing thrombosis cases — one of the main causes of strokes and heart attacks. It reduces the level of cholesterol in blood and improves the ratio of good cholesterol to bad cholesterol. It also reduces high blood pressure by repressing angiotensin-II. Polyphenols keep blood vessels from contracting and raising blood pressure. It is said to be useful to treat impaired immune function and rheumatoid arthritis. Green tea also destroys free radicals that cause aging.
