According to the pharmaceutical affairs law order reminyl 8 mg with visa medicine tablets, the Japanese deﬁnition of a cosmetic is as follows: The term cosmetic means any article intended to be used by means of rub- bing generic reminyl 4 mg medicine 2 times a day, sprinkling or by similar application to the human body for cleansing, beautifying, promoting attractiveness and altering appearance of the human body, and for keeping the skin and hair healthy, provided that the action of the article on the human body is mild. The Japanese deﬁnition is only slightly different from the deﬁnition of a cosmetic within Europe. Both deﬁnitions allow a cosmetic to have mild activity and possess pharmaceutical activity. Moreover, in article 7a of the European cosmetics directive, which de- scribes the product information requirement, it is stated that a proof of effect should be included (2). In the United States, however, a product would be re- garded as a drug if a proof of effect was mentioned. Extensive research on the physiological activity of the skin has provided evidence that even small changes in the environment can modify the activity of skin tissue (3,4). As mentioned by Gilchrest, the Food and Drug Administration asked her to deﬁne water as a drug, when water was applied on the skin under experimental condi- tions (7). Registration of a product as a drug requires many elaborate and costly procedures; therefore, the manufacturer of a product with pharmaceutical activity would prefer to have the product registered as a cosmetic. This might mean that the pharmaceutical activity of the product is not mentioned and/or investigated, and, as a result of these confusing and old-fashioned regulatory rules, important information is not given to the public. The introduction of the term ‘‘cosmeceutical’’ enables us to classify more precisely a product with an activity that is intended to treat or prevent a (mild) skin (abnormality). In order to avoid introducing new deﬁnition criteria, we sug- gest that cosmeceuticals are only regarded as a subclass within the domain of a Deﬁnition 11 Table 1 Cosmeceuticals as a Subclass of Cosmetics (Europe and Japan) and as a Subclass of Drugs (U. In Europe and Japan, cosmeceuticals can be regarded as a subclass of cosmetics; however, in the United States cosmeceuticals can only be regarded as a subclass of drugs. Cosmeceuticals could be characterized as fol- lows: (1) The product has pharmaceutical activity and can be used on normal or near-normal skin. The deﬁnition of minor skin disorders or mild skin abnormalities is difﬁcult and can be regarded as cosmetic indications. Even socioeconomic factors may have an impact on whether a skin disorder is regarded as a disease or as a cosmetic indication (8,9). Nevertheless, in most western countries there is no written consensus that skin abnormalities that are treated by over-the-counter drugs may be regarded as mild skin disorders or may be termed cosmetic indications (9,10). The procedure for registration of a cosmeceutical should not be as cumber- some as for drugs. The intended activity of the cosmeceutical for treatment of a minor skin disorder should be demonstrated by clinical studies within the frame- work of good clinical practice. Moreover, it should be shown that safety require- ments are optimal and that no side effects can be expected (11). The safety evalua- tion is mandatory for cosmetics in Europe, according to articles 2, 12, and 13. In the United States, this would mean that a subclass of drugs (cosmeceuti- cals) are registered in a similar manner as over-the-counter products (12). It would be beneﬁcial if these countries could agree on the deﬁnitions of cosmetics and drugs and, in so doing, deﬁne cosmeceuticals as a subclass of cosmetics. This would prevent the current situation in which certain products are registered as drugs in the United States (sunscreens) and as cosmetics or cosmeceuticals in Europe and Japan. Evidence that cell shedding from plantar stratum corneum in vitro involves endogenous proteolysis of desmosomal protein desmogein. Aging skin was to be accepted as an inevitable, irreversible, and trivial conse- quence of getting old. These observations have coincided with several pertinent phenomena: (1) the incredible growth of scientiﬁc knowl- edge in recent years; (2) people in western populations living longer and spending increased leisure time exposed to sun in outdoor activities; and (3) the rampant cosmetic claims for products that will ‘‘turn back the clock’’ to youth overnight. One is the northern hemisphere, where life is rigid, cold scientiﬁc proof is difﬁcult, and only the hardiest survive in the frozen tundras of pharmaceutical bureaucracy and governmental regulation. The southern hemisphere is friendly and warm and things that make you ‘‘feel’’ better are considered good, rather than inherently evil because they are not ‘‘natural’’ and may prevent us from looking our age. Advocacy of the term cosmeceutical, as an attempt to compromise and bridge the gap between cosmetic and pharmaceutical, greatly enlivened the de- bate. In fact, the debate has forced us to reevaluate what we truly believe, even made us iconoclasts, willing to listen to new ideas. It has taken place during an era of unprecedented discovery about the structure and functioning of the skin, and the discussion has begun to rise above the former shrill hysteria and is now on a higher plane of logic and scientiﬁc facts. On one hand, appearance of the facial skin makes this condition so obvious to the subject and observers, which in turn makes the use of cosmetic products so appealing.
In malarial country regions this agent will be more often indicated than in the city order reminyl 4 mg medications you can crush, as the habits and environment of city life are more apt to induce extremely opposite conditions to those which indicate Podophyllin order reminyl 4 mg otc treatment skin cancer. Administration—The physiological action does not suggest to a great degree the uses which our experience has taught us to make of this remedy. The drastic cathartic influence we do not need, as it is too harsh in its active influence. From five to thirty drops of the tincture in a four ounce mixture, or from one two hundredths to the one-twentieth grain of Podophyllin, will be found sufficiently active. Specific Symptomatology—This agent is demanded in inactive, conditions of the gastro-intestinal tract, indicated by a heavily coated tongue, which is thick, broad and pale, and the coat of dirty yellow color especially at the base, together with perhaps vertigo, complete anorexia, and dull, heavy headache. The circulation is full and sluggish, and the abdominal viscera is in a plethoric condition. Therapy—These conditions will suggest the use of the agent whatever Ellingwood’s American Materia Medica, Therapeutics and Pharmacognosy - Page 355 the name of the existing disease. In acute inflammatory conditions, or in irritable conditions of the stomach or bowels, it is contra-indicated in active doses. In the condition known as biliousness, with markedly inactive liver, sallow skin and conjunctiva, constipation, highly colored urine containing uric acid, urates in great excess, and bile, it is of value. In these cases the following formula, although unpleasant to the taste, will be of great service: Tincture of podophyllum, tincture of leptandra, of each half a dram; tincture of capsicum twenty minims; syrup of liquorice. If there is enlargement of the liver, with general indisposition, soreness over the liver and pain through the right side and under the right scapula, it is the remedy. In inactivity of the liver characterized by constipation, the feces when passed being solid or hard and of a grayish or clay color, and floating upon water, with general indisposition, podophyllin may be given in doses of one-fiftieth of a grain every two or three hours. If there is a great sluggishness with obstinate constipation, one-tenth of a grain may be given for two or three doses, the smaller doses to follow. If given for its cathartic influence it should be combined with hyocyamus or belladonna, or it may be given in conjunction with leptandra virginica. Podophyllin, in from one-half to one grain doses repeated once or twice, and followed by half a pint of pure olive oil, is reasonably sure treatment in the removal of gall stones. The agent in minute doses will permanently cure some conditions which cause chronic constipation, but if desired for this purpose, like cascara, it must at no time be given in full active doses. Locke advises a teaspoonful of a mixture of thirty grains of the second decimal trituration in a half glass of water to be given a child three times each day for constipation. In minute doses it will stimulate intestinal secretion and peristaltic action in children, and overcome dry stools, and constipation and Ellingwood’s American Materia Medica, Therapeutics and Pharmacognosy - Page 356 bloated bowels, with erratic colicy pains. In the treatment of hemorrhoids accompanied with constipation from deficient peristalsis and general abdominal plethora, podophyllum is of direct service. It can be given in conjunction with collinsonia and the effects are marked from the first. The writer has prescribed the tincture or fluid extract of podophyllum for several years as an alterative. If the plethoric conditions named as indicating it are present, it is much more active, and is always to be given in doses sufficiently small to avoid any irritating or cathartic effects. In skin diseases of childhood, such as cracked and fissured conditions of the skin of the face, or eczema, or persistent pustular conditions, it is of value. It may be prescribed with most happy results with other alteratives in scrofula or syphilis, or in the eruptions which result from these disorders. Younkin is authority for the use of this agent in one-sixth of a grain doses, with ten grains of the potassium bitartrate, given every two hours in gonorrheal epididymitis, of which it relieves the pains and abridges the inflammation. Physiological Action—Senega has sustained a reputation in the past, as an antidote to the poison of venomous reptiles. It is an alterative of much power, exercising a marked influence upon both the skin and mucous membranes, notably the latter. Ellingwood’s American Materia Medica, Therapeutics and Pharmacognosy - Page 357 It causes a sensation of acridity in the throat when a moderate dose is swallowed, and may be employed in chronic pharyngitis, as a local stimulant, where the mucous membrane is relaxed and the secretion abundant. Specific Symptomatology—The agent is indicated in typhoid pneumonitis, capillary bronchitis, in aged and debilitated subjects, chronic bronchitis with profuse secretion, in the declining stages of pneumonitis, bronchitis and croup, when the inflammatory condition has passed off, chronic bronchitis with pain and soreness in the chest and asthma. Therapy—The agent is in use in the treatment of dropsy from obstruction and glandular enlargement, also in rheumatism, syphilis, squamous skin diseases and in amenorrhea. Senega has been employed as a stimulating expectorant in chronic bronchitis, in aged and debilitated subjects, where a stimulating medicine is demanded and in the later stages of pneumonia and catarrhal inflammations.

After its takeover of Boehringer Mannheim, Roche devel- oped the Penzberg site into one of Europe’s biggest bio- technology centres. Finally, its ac- quisition of a majority stake in the Japanese pharmaceu- ticalandbiotechnology com- pany Chugai in 2002 put the Roche Group close behind the world market leader Amgen in terms of biotech sales. Its competitors have fol- lowed a similar course, though in some cases later or with different focuses. Boehringer & Söhne, under- first recombinant drug to be discovered, developed and pro- takes biochemical work in the former Hotel Simson in Tutzing. The resulting expertise has paid off: The Roche Group Syntex and in 1995 converts it into Roche Biosciences. Roche’s returns 42% of the company’s shares to the stock market; the Diagnostics Division supplies over 1700 biotechnology-based monoclonal antibody Herceptin is approved for use in breast products.

Japan: potential in Compared to their counterparts in Europe, the biotechnology pharmaceutical companies of the various Asian countries – which are otherwise so enthusiastic about new technology – were slow to recognise the potential of this new industrial sector. This despite the fact that the Japanese pharmaceutical market is the world’s second largest, after that of 20 Number one in Japanese biotechnology: Chugai Pharma 1925 Juzo Uyeno founds a small pharmaceutical company in Tokyo that becomes increasingly impor- tant nationally over the coming decades.

Moreover, two Japanese companies, Takeda and Sankyo, rank among the 20 largest pharmaceutical companies in the world. In the 1990s Japan set out on the road to catch up, in particular via large-scale support programmes and targeted alliances. The result is that Japanese pharmaceutical companies are now at least on a par with their counterparts in most European coun- tries in terms of sales of biopharmaceutical products. However, the country still lags behind in terms of the number of biotech companies based there, the period of rapid expansion in the 1990s having largely passed Japan by. As yet,Japanese companies devoted exclusively to modern biotechnology have an even smaller slice of the world market than their European competi- tors. Japanese biotechnology is largely in the hands of representatives of classical branches of industry such as the brewery Kirin, the food manufacturer Takara, the chemical manufacturer Kyowa Hakko and variouspharmaceutical companies. Themarket lead- er in modern biotechnology in Japan is Chugai Pharmaceutical Beer for Babylon 21 Co. Milestones along this company’s development in this area were its acquisition of the American biotech company Gen-Probe in 1989 and, a year later, the granting of regulatory approval for its first genetically engineered drug, Epogin (active ingredient: erythropoietin, for use in anemia). Access to the worldwide market for these products is provided by the Roche Group, which acquired a majority stake in Chugai in 2002. The merger between Nippon Roche, Roche’s Japanese subsidi- ary, and Chugai in 2002 led to the formation of Japan’s fifth- largest pharmaceutical company and largest biotech company. Chugai operates as an independent member of the Roche Group and is listed separately on the stock exchange. It is responsible for the sale of all Roche products in Japan and also benefits from the Group’s worldwide sales network; for its part, Roche has li- censee rights to all Chugai products marketed outside of Japan or South Korea. Prospects: As seen from the example of the Roche Group, biotechnology in small, innovative biotech companies are increas- transition ingly entering into alliances with big pharma- ceutical companies. At the same time, the big companies have expanded their portfolios by acquiring majori- ty stakes in biotech companies listed separately on the stock exchange and by entering into alliances in this area.
The resulting reaction force pushes back on the body and retards its motion—this is the source of ﬂuid friction in air buy reminyl 4mg overnight delivery medicine overdose. We can deduce some of the properties of air friction by sticking our hand outside a moving car order reminyl 8 mg overnight delivery medications management. Clearly, the greater the velocity with respect to the air, the larger is the resistive force. By rotating our hand, we observe that the force is greater when the palms face the direction of motion. We therefore conclude that the resistive force increases with the velocity and the surface area in the direction of motion. Because of air resistance, there are two forces acting on a falling body: the downward force of gravity W and the upward force of air resistance. From Newton’s second law (see Appendix A), we ﬁnd that the equation of motion in this case is W − Fa ma (3. If the body falls from a suﬃciently great height, the velocity reaches a magnitude such that the force due to air resistance is equal to the weight. Past this point, the body is no longer accelerated and continues to fall at a constant velocity, called the terminal velocity vt. At the terminal velocity, the downward force of gravity is canceled by the upward force of air resistance, and the net acceleration of the body is zero. The weight of an object is proportional to the volume, which is in turn proportional to the cube of the linear dimension L of the object, 3 W ∝ L The area is proportional to L2. With proper training, a person can jump from a height of about 10 m 42 Chapter 3 Translational Motion without sustaining serious injury. From this height, a person hits the ground at a speed of v 2gs 14 m/sec (46 ft/sec) Let us assume that this is the speed with which any animal can hit the ground without injury. At this speed, the force of air resistance on an animal the size of man is negligible compared to the weight. A simple calculation shows that a mouse can fall down a 100-m mine shaft without severe injury. Air friction has an important eﬀect on the speed of falling raindrops and hailstones. Without air friction, a 1-cm diameter hailstone, for example, falling from a height of 1000 m would hit the Earth at a speed of about 140 m/sec. As it is, air friction slows the hailstone to a safe terminal velocity of about 8. The energy required to perform the work is obtained from the chemical energy in the food eaten by the animal. In general, only a small fraction of the energy consumed by the muscles is converted to work. For example, in bicycling at a rate of one leg extension per second, the eﬃciency of the muscles is 20%. In other words only one ﬁfth of the chemical energy consumed by the muscle is converted to work. The energy consumed per unit time during a given activity is called the metabolic rate. In most cases, the eﬃciency of the muscles in converting caloric food energy to work is less than 20%. We will calculate the amount of energy consumed by a 70-kg person jump- ing up 60 cm for 10 minutes at a rate of one jump per second. The external mechanical work performed by the leg muscles in each jump is Weight × Height of jump 70 kg × 9. In the calculation, it is assumed that most of the work done in running is due to the leg muscles accelerating each leg to the running speed v, and then decelerating it to 0 velocity as one leg is brought to rest and the 1 2 other leg is accelerated. As is shown in Exercise 3-9, typically, a 70-kg person (leg mass 10 kg) running at 3 m/sec (9-min. Theenergyrequiredtoovercome air resistance in running is calculated in Exercise 3-10. In connection with the energy consumption during physical activity, we should note the diﬀerence between work and muscular eﬀort.
