The need for warmth, food, love, and sex are all forms of instinct, but the instinct for survival is probably the most powerful.... instinct
Gender is determined by a combination of genetic and environmental factors, in which the in?uence of family upbringing is an important factor. When physical sexual characteristics are ambiguous, the child’s gender identity can usually be established if the child is reared as being clearly male or female. Should, however, the child be confused about its sexual identity, the uncertainty may continue into adult life. Transsexuals generally experience con?icts of identity in childhood, and such problems usually occur by the age of two years. In this type of identity disorder, which occurs in one in 30,000 male births and one in 100,000 female births, the person believes that he or she is the victim of a biological accident, trapped in a body different from what is felt to be his or her true sex.
Treatment is di?cult: psychotherapy and hormone treatment may help, but some affected individuals want surgery to change their body’s sexual organs to match their innately felt sexual gender. The decision to seek a physical sex change raises major social problems for individuals, and ethical problems for their doctors. Surgery, which is not always successful in the long term, requires careful assessment, discussion and planning. It is important to preclude mental illness; results in homosexual men who have undergone surgery are not usually satisfactory.

It is when a particular stress is intense that the immune system may lack the vitality to mobilise the body’s resources against a threat to its safety and well-being.
Adaptogens are concerned with the therapeutic action of the whole plant which is regarded as greater than the sum of its parts. They may affect many different kinds of cells, whereas a chemical drug has a direct action upon a particular tissue or system.
Adaptogens are powerful supportive agents against stress and its effects, initiating processes of regeneration of tissues and fluids. They release innate resources of vitality in their efforts to reinvigorate and protect.
This important group includes: Siberian and Asiatic Ginseng, Borage, Don Quai, Gotu Kola, Lapacho tea, Pollen extracts, Royal Jelly, Sarsaparilla, Shiitake Mushroom, Suma. ... adaptogen
The term innate immunity is given to the protection that we are born with, such as the skin and the mucous membranes that line the mouth, nose, throat, intestines, and vagina. It also includes antibodies, or immunoglobulins (protective proteins), that have been passed to the child from the mother. If microorganisms penetrate these defences, they encounter “cell-devouring” white blood cells called phagocytes, and other types of white cells, such as natural cellkilling (cytotoxic) cells. Microorganisms may also meet naturally produced substances (such as interferon) or a group of blood proteins called the complement system, which act to destroy the invading microorganisms.The 2nd part of the immune system, adaptive immunity, comes into play when the body encounters organisms that overcome the innate defences. The adaptive immune system responds specifically to each type of invading organism, and retains a memory of the invader so that defences can be rallied instantly in the future.
The adaptive immune system first must recognize part of an invading organism or tumour cell as an antigen (a protein that is foreign to the body). One of 2 types of response – humoral or cellular – is then mounted against the antigen.
Humoral immunity is important in the defence against bacteria. After a complex recognition process, certain B-lymphocytes multiply and produce vast numbers of antibodies that bind to antigens. The organisms bearing the antigens are then engulfed by phagocytes. Binding of antibody and antigen may activate the complement system, which increases the efficiency of the phagocytes.
Cellular immunity is particularly important in the defence against viruses, some types of parasites that hide within cells, and, possibly, cancer cells. It involves 2 types of T-lymphocyte: helper cells, which play a role in the recognition of antigens and activate the killer cells (the 2nd type of T-lymphocyte), which destroy the cells that have been invaded.
Disorders of the immune system include immunodeficiency disorders and allergy, in which the immune system has an inappropriate response to usually innocuous antigens such as pollen.
In certain circumstances, such as after tissue transplants, immunosuppressant drugs are used to suppress the immune system and thus prevent rejection of the donor tissue as a foreign organism.... immune system
Treatment of mutism due to psychological causes is now increasingly by behavioural means, such as *prompting: people that the patient does not address are slowly introduced into the situation where the patient does speak. This may be done either alone or in combination with more traditional psychotherapy. Psychotic or depressive mutism or *catatonia are addressed by treating the underlying condition. —mute adj., n.... mutism
