Complete Process of Biological Packaging

For protective transfer of crucial biological agents it is necessary to have an enhanced biological packaging process done under stringent standards. There are various forms of biological products which include infectious particles of plants, animals and humans as well as multiple types of toxins which are produced by genetic materials or microbes. Such organic agents may be present in concentrated and purified cultures but may also exist in plenty of distinct types such as body tissues, fluids, sample of soils, solid substances and more. No matter what the form is, it is essential to carry every product in secured form for which an effective packaging process is of utmost relevance.

The main purpose of any sort of packaging methodology is to protect the products which are being shipped from getting reacted with chemicals and toxic substances present in air. So only biological packaging which is framed under rigid standards must be considered by professionals. The packaging must be done in such a way and must be strong enough that it enables easy transportation of crucial elements through all means i.e. air, water or land. There are some products which require certain minimum temperature level even when they are transported in order to protect them from getting spoiled and unsuitable for use. So, even this factor must be considered while carrying the packaging process for these products.

The basic requirements for any type of biological packaging process are that it should be a 'triple packing' process. This implies that it should be primarily receptacle, must be strictly water tight packing as well as totally robust from outer arena. In addition to this, there must be an 'Infectious Substance' label on every product packed in order to protect individuals from getting in direct contact with it. It must be a certified packing methodology and meet all prior tests outlined for it in the USPS, DOT, IATA and PHS regulations. Only after all these functionalities are properly met, a packaging is considered ideal to be used for shipment purposes.

A 'triple' biological packaging process is also required for all clinical specimens. One additional fact however, with packaging of such products is that they must be able to fulfill all performance based examinations and that the packaging must not leak even after carrying a '4-drop test'. Even the items which are employed for packing these materials must be highly powerful and free from all kinds of ill-effects such as leakages, breakages. They must be totally air tight units. Only if the packaging is able to meet rigorous standards, rough handling and can provide protection to hazardous materials from all other toxin materials, it is considered as highly suitable.

Transportation of biological materials poses greater challenges in comparison to shipment of chemical based substances. For this reason, it becomes essential that these products must be packed with highly qualitative and effective packing techniques only. Bottles, vials, rollers, crimps, aluminum seals are some of the items which are used for this process. No matter what product is to be packed, the complete process of biological packaging for it must be done with due diligence.

Wound Healing Process

Wounds are of numerous types-from a simple cut on a finger to a ghastly gash anywhere on the body. Though knowledge of first-aid is essential for attending to accidental injury in an emergency, yet a thorough understanding of the process of wound healing and other accompanying factors can play a significant role in better wound management.

Wound healing is a complex phenomenon which depends upon a number of factors. It is amazing to note that the natural process of healing gears into action as soon as the injury occurs-which could either be an internal injury with bleeding occurring inside the wound site or an external one with the blood oozing out of the open wound.

Bleeding occurs when a blood vessel is damaged. If the vessel is internal, blood seeps into surrounding tissue, and a bruise forms. It has been observed by Doctors that minor bleeding causes no harm because the body soon stops it, by means of three mechanisms that act together:

i. The nearby blood vessels contract and restrict the flow of blood to the area of the wound.
ii. The platelets in the blood gather where the blood vessels are damaged and stick to the vessel walls and to each other to form a plug.
iii. In addition, interlacing strands of material called fibrin form in the damaged area. Blood cells are trapped in the fibrin mesh and form a clot that seals the break and effectively stops the bleeding.

In sharp contrast, when the bleeding is occurring out of an open wound, the healing process primarily involves three phases-which may or may not overlap each other. These healing phases are widely known as:

(a) Inflammatory phase;
(b) Proliferative phase; and
(c) Remodelling phase. Each phase is being discussed as follows:

(a) Inflammatory Phase: This phase gears into action as soon as the injury occurs and continues for approximately five days. The natural clotting mechanism springs into action and platelets (minute bodies in blood) gather to stop the bleeding. After about 24 hours, debridement (removal of damaged or infected tissues) starts due to the action of enzymes-and dead tissues, bacteria and unwanted elements are removed from the wound site. The natural process also allows the passage of beneficial fluids from the blood vessels to the wound. Simultaneously, new blood vessels and tissues begin to form.

(b) Proliferative Phase: This phase begins during the first three weeks of the injury. Different types of cells and collagen (a protein which is a major component of a connective tissue) start to settle in the wound. Granulation (formation of small elevations on the wound surface) occurs in this phase. The wound's opening closes down after it is covered with a new ephthelial layer.

(c) Remodelling Phase: Depending upon the magnitude and gravity of the wound, this last phase may continue up to two years. In this phase, the body is in the process of regaining its original stature which is marred by the formation of a scar at the site of the wound.

It is relevant to point out that while the natural repair process automatically engages into repairing the injured site, there are certain conditions which either hinder or help the healing process. Injuries suffered by a diabetic patient take a very long time to heal-more specifically if the blood sugar is not properly controlled.

On the other hand, proper nutrition certainly helps in speeding up the healing process. The body needs adequate amounts of calories, protein, vitamins and minerals to tone up the immune system to fight back the germs at the site of the wound. Good nutrition does not necessarily imply any special kind of diet. A balanced diet consisting of vegetables, fruits, whole grains and lean meat in the right proportions is all that is required for maintaining a healthy body capable of resisting the onslaught of the maladies.
