In the last decade it has become quite clear that oxygen free radicals are involved in a vast amount of diseases such as cataract, atherosclerosis, rheumatism, arthritis, Parkinson's disease, reperfusion injuries and many others. The induction of defence systems against certain stresses (heat shock, inflammation) is also mediated by activated oxygen species. Oxygen-activation and -desactivation has to be regulated and well attenuated in aerobic cells and tissues. The biochemical basis of the biological efficacy of oxidants is thus based on a sophisticated balance between catalysis of production and reactivity of oxygen radicals by certain cofactors and transition metals on the one hand and on a reliable detoxification by antioxidants or metabolic chains on the other hand. In this communication, different oxygen activating principles are compared and the biochemical basis for the induction of repair processes by a synthetic heme oxidant, (Tetrachlorodecaoxide, TCDO) is presented.

The antioxidative effect of various drugs on lipid peroxidation in rat serum in the presence of FeSO4 was studied. The concentration of TBA-active products decreased in the presence of carnosine and anticataract drugs (Japanese Catalin, Chinese Baineiting and Finnish Catachrom-OFTAN). Vita-iodurol (France) and Quinax (USA) were completely inert. One of feasible mechanisms underlying certain pathologies (cataract, rheumatism, etc.) is the damage of biomembranes by active oxygen species. The potent antioxidative activity of carnosine reflects the high therapeutic value of this compound.

A 5-year observation over 510 patients with initial senile cataract allowed to attribute to a group of risk relatives of the patients with senile cataract; persons who had suffered endocrine diseases; those with cardiovascular pathology; those who had suffered viral infections, rheumatism, renal and hepatic diseases; such workers, as drivers, founders, smiths, stockers, agricultural workers, teachers, lawyers. After 35 years of age, the patients of the group of risk should be yearly examined by the ophthalmologist. In case of general diseases, the main disease and disturbed turn-over should be treated. For local treatment and prevention of progression of senile cataracts the most effective are drops of catachrome, methyluracil with insulin. As to general treatment, it is recommended to use angioprotectors, methyluracil, tissue therapy.

The study investigated the Taiwanese elderly in two different ethnic groups (Paiwan and Min-Nan) regarding their multifunctional status. The purpose was to make known and compare the subjective and objective health status of these two groups. The results for the objective measurements indicated that an elderly Paiwanese had 2.74 kinds of diseases on average. The most prevalent diseases among the Paiwan elderly were arthritis (rheumatism), circulation troubles in arms or legs, high blood pressure, stomach or intestinal disorders or gall bladder problems, cataract, heart trouble, emphysema (chronic bronchitis), skin disorder (leg ulcers or severe burns), asthma, and digestive system ulcers. Of all disease, five (arthritis, circulation trouble, emphysema, skin disorder, and tuberculosis) were statistically more prevalent among the Paiwan elderly than among the Min-Nan elderly. In terms of health scoring, the two groups were comparable except in the following two aspects: (1) more Paiwan elderly were unable to take medicine by themselves, and (2) the Paiwan elderly had lower cognitive ability ratings. In the subjective arena, the Paiwan elderly had a lower score in self-rating health status. Condensed, the health status of the Paiwan was worse than that of the Min-Nan elderly both in objective and subjective measurements.

Since ancient times, plants and herbal preparations have been used as medicine. Research carried out in last few decades has certified several such claims of use of several plants of traditional medicine. Popularity of Momordica charantia (MC) in various systems of traditional medicine for several ailments (antidiabetic, abortifacient, anthelmintic, contraceptive, dysmenorrhea, eczema, emmenagogue, antimalarial, galactagogue, gout, jaundice, abdominal pain, kidney (stone), laxative, leprosy, leucorrhea, piles, pneumonia, psoriasis, purgative, rheumatism, fever and scabies) focused the investigator's attention on this plant. Over 100 studies using modern techniques have authenticated its use in diabetes and its complications (nephropathy, cataract, insulin resistance), as antibacterial as well as antiviral agent (including HIV infection), as anthelmintic and abortifacient. Traditionally it has also been used in treating peptic ulcers, interestingly in a recent experimental studies have exhibited its potential against Helicobacter pylori. Most importantly, the studies have shown its efficacy in various cancers (lymphoid leukemia, lymphoma, choriocarcinoma, melanoma, breast cancer, skin tumor, prostatic cancer, squamous carcinoma of tongue and larynx, human bladder carcinomas and Hodgkin's disease). There are few reports available on clinical use of MC in diabetes and cancer patients that have shown promising results.

Curcumin is the active ingredient of turmeric that has been consumed as a dietary spice for ages. Turmeric is widely used in traditional Indian medicine to cure biliary disorders, anorexia, cough, diabetic wounds, hepatic disorders, rheumatism, and sinusitis. Extensive investigation over the last five decades has indicated that curcumin reduces blood cholesterol, prevents low-density lipoprotein oxidation, inhibits platelet aggregation, suppresses thrombosis and myocardial infarction, suppresses symptoms associated with type II diabetes, rheumatoid arthritis, multiple sclerosis, and Alzheimer's disease, inhibits HIV replication, enhances wound healing, protects from liver injury, increases bile secretion, protects from cataract formation, and protects from pulmonary toxicity and fibrosis. Evidence indicates that the divergent effects of curcumin are dependent on its pleiotropic molecular effects. These include the regulation of signal transduction pathways and direct modulation of several enzymatic activities. Most of these signaling cascades lead to the activation of transcription factors. Curcumin has been found to modulate the activity of several key transcription factors and, in turn, the cellular expression profiles. Curcumin has been shown to elicit vital cellular responses such as cell cycle arrest, apoptosis, and differentiation by activating a cascade of molecular events. In this chapter, we briefly review the effects of curcumin on transcription factors NF-KB, AP-1, Egr-1, STATs, PPAR-gamma, beta-catenin, nrf2, EpRE, p53, CBP, and androgen receptor (AR) and AR-related cofactors giving major emphasis to the molecular mechanisms of its action.
