Ono K, Hasegawa K, Naiki H, Yamada M (2004) J Neurosci Res 75:742 Chapter 3 Research into Isofavonoid Phyto-oestrogens in Plant Cell Cultures M. The physiological and pharmacological properties of isofavones are discussed in the Introduc- tion. The accumulation of phyto-oestrogens by plant cell and tissue cultures is reviewed. A special emphasis is put on the infuence of basic experimental me- dia and physiological factors on the production of isofavonoids in in vitro cul- tures. The potential role of the transformation process as well as the techniques (including infection with bacteria and particle bombardment) and the various technological procedures (elicitation, feeding experiments) in isofavone bio- synthesis is discussed. Moreover, this chapter deals with the in vitro cultures of legume plants oriented for selective accumulation of phyto-oestrogens. Strictly controlled conditions and constant access to stable biological material made it possible to conduct basic research into plant physiology on a much larger scale than before, leading to the expla- nation of numerous biochemical processes that constitute primary and second- ary tissue metabolism [3, 4]. It was also proved that plant biomasses cultivated in vitro are capable of biosynthesis of secondary metabolites typical for intact plants, or that they may serve as sources of entirely new substances not identi- fed in nature [3–10]. In effect, a path was opened for intensive biotechnological research into the potential use of in vitro cultures to produce highly valuable secondary metabolites, including compounds for which medical applications could be found [10–13]. Statistical research indicated that even in developed countries, where the broadly understood chemical synthesis is the basis for the pharmaceutical in- dustry as such, still as much as 25 % of all medicines are compounds of natural origin. Steady degradation of the environment, slow growth of plants, com- mon problems with low concentrations of active substances in the cultivated plants are only some of the factors that make it diffcult to obtain biologically active substances from natural sources. With the aforementioned obstacles and the need to cultivate tropical species in a temperate climate, in vitro cultures came to be seen as an alternative method for producing secondary metabolites with particularly valuable therapeutic properties [3, 14]. Among the numerous secondary metabolites, it is isofavonoids, together with alkaloids and terpenoids, that are natural compounds most commonly re- searched under in vitro conditions [9, 10, 15]. The reason for this may be seen in their multidirectional biological activity [16, 17]. Isofavones, being recognised phytoalexins and phytoanticipins, play a key role in the defence mechanisms in plants of Fabaceae family. That is why plant biomasses obtained from various species of legume plants became model systems for testing the defence response of plants to broadly defned environmental stresses [18, 19]. Isofavones are, in addition, secondary metabolites with broad health-promoting activity. In ad- dition to the anti-infammatory, antifungal and anti-free-radical activities that are typical for the whole group of biofavonoids, they also have features typical for compounds that inhibit oestrogen β receptors in mammals [16, 17, 20–22]. For this reason, among other applications, they are commonly recommended for the treatment of menopause symptoms [21, 23]. Moreover, some consider- ation is given to the possible using isofavones in the prevention and treatment of neoplasms related to the distortion of hormonal balance in the body [16, 17, 22, 24, 25]. Predominantly limited to soy-bean products, the natural sources of isofavones do not permit mass production of substantial amounts of these compounds, not only for the pharmaceutical industry, but also for the compre- hensive pharmacological and toxicological research of the isolated substances Chapter 3 Research into Isofavonoid Phyto-oestrogens in Plant Cell Cultures 57 . Therefore, in recent years, only very few reports dealing with biotechno- logical research indicated the possibility of using in vitro cultures of certain species of the Fabaceae family for large-scale production of phyto-oestrogens [27, 28]. Irrespective of the main goal of a research project, the biosynthesis and metabolism of isofavonoids is stimulated in in vitro cultures by using both traditional as well as more advanced biotechnological strategies [15, 26]. Such procedures as the modifcation of the basic composition of the experimental medium, with a focus on growth regulators [29–33] and the regulation of the growth conditions by controlled lighting and temperature, should be mentioned [30, 34, 35]. The natural enzymatic potential of the investigated biomass is also used to induce broadly understood bioconversion with the use of direct and indirect precursors, in order to obtain the fnal product [36–38]. Based on the fact that isofavones belong to a class of substances that play an active role in defence processes [18, 19], the biosynthesis and metabolism of these compounds in plant cells is regulated using a wide range of biotic and abiotic elicitors [39–43]. Sample tests of isofavone accumulation in various types of in vitro cultures (callus, suspension, roots and shoots) provide prelimi- nary insight into the production potential of the particular types of cultures [27, 28, 31–33, 44]. The metabolism of isofavones was also investigated using transgenic biomasses (suspensions, hairy roots, regenerated organs) obtained through genetic transformation with wild or pre-designed strains of bacteria [31, 45–47], or particle bombardment [48, 49].

Oxacillin would be the drug of choice only if the incidence of methicillin-resistant staph is very low generic myambutol 600mg fast delivery x3 antimicrobial hand sanitizer. Quinolones are often useful in the treatment of community-acquired pneumonia buy myambutol 800mg virus mutation rate, but they would not be effec- tive against methicillin-resistant staph. Sputum culture and sensitivity can direct specific antibiotic therapy for the patient as well as provide epidemiologic information for the community as a whole. A good sputum sample showing many polymorphonuclear leuko- cytes and few squamous epithelial cells can give important clues to etiology. A Gram stain that shows gram-positive lancet-shaped diplococci intracellu- larly is good evidence for pneumococcal infection. Empirical antibiotic ther- apy becomes more difficult in community-acquired pneumonia as more pathogens are recognized and as the pneumococcus develops resistance to penicillin, macrolides, and even quinolones. Treat- ment of high-risk patients, such as this patient, should be supervised, and multidrug resistance should be assumed. Ingestion of and infection with this organism may result in a spec- trum of illnesses, including mild diarrhea, hemorrhagic colitis with bloody diarrhea, acute renal failure, and death. Infection has been associated with ingestion of contaminated beef (in particular ground beef), ingestion of raw milk, and contamination via the fecal-oral route. Cooking ground beef so that it is no longer pink is an effective means of preventing infection, as are hand washing and pasteurization of milk. As the ability to more rapidly diagnose some of these diseases increases, their likelihood of causing undi- agnosed persistent fever lessens. Self-limited infections such as influenza should not cause fever that persists for many weeks. Since conditions such as systemic lupus erythematosus are more easily diagnosed today, they are less frequent causes of this syndrome. Factitious fever is most com- mon among young adults employed in health-related positions. A prior psychiatric history or multiple hospitalizations at other institutions may be clues to this condition. Such patients may induce infections by self- injection of nonsterile material, with resultant multiple abscesses or polymicrobial infections. In these cases, a discrepancy between temperature and pulse or between oral temperature and witnessed rectal temperature will be observed. Following cardiac catheterization, blood cultures obtained from a distal vein are rarely positive. Thus, prophylactic antibiotics are not currently recommended for cardiac catheterization. Bacteremia commonly occurs following other procedures such as periodontal surgery, tonsillectomy, and prostate surgery. The animals that present the most danger are wild skunks and bats; foxes are also possible carriers. Raccoons are responsible for an increasing num- ber of cases in the mid-Atlantic states. The incubation period ranges from 4 days to many years, but is usually between 20 and 90 days. The incuba- tion period is usually shorter with a bite to the head than with one to an extremity. In humans, only four definite recoveries from established infec- tion have been reported. Nonimmunized animals that have been bitten should be killed and their brains submitted for virus by immunofluores- cent antibody examination. A negative fluorescent test removes the need to treat the bite victim either actively or passively. This disease most com- monly affects children between the ages of 5 and 14 years, but it can also occur in adults. The disease is characterized by a slapped-cheek rash, which may follow a prodrome of low-grade fever. Complications in adults include arthralgias, arthritis, aplastic crisis in patients with chronic hemolytic anemia, spontaneous abortion, and hydrops fetalis.
