Title of the Research Study

A STUDY ON THE ALLERGY CAUSED BY PRAWNS/SHRIMPS (Crustaceans – Shell Fish)

Abstract:

Allergy reactions by consumption of foods has been the serious questions, doesn’t matter it consumed as nutritional food or value. In the doctrine studies related to the allergy, consumption of foods like, peanuts, ginger, cilantro, prawns etc create chemical reactions inside the body.  The objective of the study is to analyses here about ‘Allergy causing by Prawns/Shrimps’. There are so many mislead and wrong perception on allergic part by normal or we can say regular people, normally there are 4 types of Allergen, immediate, cytotoxic, immune-complex mediated and delayed hypersensitivity reactions. Thus, reducing the allergen city of shrimp will be helpful to every individuals whose immune or consumption system are very sensitive to shrimp and for this reason the characteristics of each allergen need to be studied. There is certain allopathy, Ayurvedic, herbal medicine to cure after getting trigger by prawns/shrimps. But, the researchers are on why, after consumption of prawns/shrimps get Tingling sensation or itching in and around the mouth, Swelling of the lips, tongue, face, throat or other parts of the body, Hives, itching or eczema, Cough, wheezing or trouble breathing,  Nasal congestion, Abdominal pain, nausea, vomiting, diarrhoea, Dizziness, light headedness or fainting, Anaphylaxis. This review will provide a better understanding of each allergen derived from shrimp which subsequently will help to reduce the allergen city.

Key Words: Crustaceans, Shell fish, allergy, allergen, prawns, shrimp

Introduction:

Reaction in and on the human body has become the regular aspect in human life majorly, prawns. Prawns has lots of nutrition’s like it contain vitamins (A & E, B12, B6) and minerals like calcium, phosphorous, potassium, etc and niacin. It is also a rich source of iron. Prawns allergies are said to be more often, the prawns lover who want to eat but could not able to take due to the immune system’s which response to a protein found in a prawns muscles which is called tropomyosin(contractile protein). To fight with the tropomysin, Antibodies release chemicals called histamines to attack the tropomyosin. The histamine release leads to a number of symptoms which effects within the body, like contraction of smooth muscle tissues of the lungs, uterus, and stomach, the dilation of blood vessels, the stimulation of gastric acid, a range from mild to life-threatening.

Review of literature:

Lead researcher Li Zhenxing (Copyright 2007) says his team found treating prawns with a combination of heat and irradiation significantly reduced the level of reactive proteins called allergens. They took blood from patients with shrimp allergies, added samples of treated and untreated prawn and measured how antibodies in the blood reacted. They found that levels of one of the major allergens decreased 20-fold after treatment. The research is reported in the magazine Chemistry & Industry.

Claveland Stae University, Ohio, report say that “If you have a shellfish allergy, you may need to remove all shellfish from your diet to avoid uncomfortable and potentially life-threatening symptoms”. The good news is that a shellfish allergy is very manageable. By avoiding shellfish and taking some precautions, you can enjoy an active, healthy life. Anyone can develop a shellfish allergy — even if you’ve had shellfish before without any problems. Although it can occur at any age, it appears more often in adults than in children. About 60% of people who have a shellfish allergy first get symptoms as an adult. The reason may be that children typically don’t eat shellfish. People often eat shellfish for the first time as adults, which may be why symptoms appear later in life.

Mayo Clinic,13400 E. Shea Blvd.Scottsdale, AZ 85259  Shellfish allergy is an abnormal response by the body’s immune system to proteins in certain marine animals. Marine animals in the shellfish category include crustaceans and mollusks, such as shrimp, crab, lobster, squid, oysters, scallops and others.Some people with shellfish allergy react to all shellfish; others react to only certain kinds. Reactions range from mild symptoms — such as hives or a stuffy nose — to severe and even life-threatening.

 Medically reviewed by Elaine K. Luo, M.D. — Written by Michael Kerr — Updated on March 8, 2019: Most people who are allergic to one type of shellfish are also allergic to the other type. There’s a chance you may be able to eat some varieties. However, doctors usually recommend that people with shellfish allergies avoid all varieties to be safe. A shellfish allergy is different from other allergies in other ways, as well. For example, allergic reactions to shellfish are unpredictable, sometimes occurring long after a person has consumed the allergen and has shown no other symptoms. Allergic reactions to shellfish also often become more severe with each exposure.

Objectives: The main aim of the study is to understand and evaluate the allergen study and give a bright awareness to the consumers. Considering the broad objective following points are specifically framed.

• To Understand the protein level in human body
• To Understand the different symptom to different person
• To understand the tropomyosin (protein found in prawns)
• To understand, the effect of histamines-the antibodies within the body
• To understand whether shell fish – prawns can able to balance the proteins in our body

 Hypothesis:

H0: There is no effect

H1: There is no significant system, prawns do balance the protein system by releasing histamine which is the antibodies.

H1: There is positive and negative effect. Prawns has immense level of vitamins (A & E, B12, B6) and minerals like calcium, phosphorous, potassium, etc and niacin but at the same time protein found in the prawns called tropomysin give negative response to the human body that is because of Low immunity system.

HO: Tropomysin in Shell fish – prawns cannot balance proteins in our body
