SUMMARY

In the last decade of this century XX, huge transformations occur on the world and consequently changes the people’ lives. Knowing agents that act in this process, analyze the tendencies check effects and results, had become essential for rational work with this communities. Certain social categories has less flexibility, so they are more damage than others. With the open market, globalism, electronic communication and e-commerce very efficient, the professional procedures must present a compatible profile with the new world. Research was accomplished in the community of the Barbarians and in the partnership places that the producing of the community used, in the period of May to November of 1999 in stratum of properties with area of up to 50 there is, that corresponds at 98,6% of the community’s strata. The results showed tendency of substitution of the cultures of cereals for vegetables in the small ones and minipropriedades and as smaller the property more quickly these changes are processed. It was verified that would seem her it is need of the mini and small producers for reduction of risks and modernization of the production systems. The changes happened in the activities coincide with the market changes, negotiation with MERCOSUL and globalização. The size of the property defines the culture type with tendency in them personal computer and small properties to the disappearance of the cultivation of cereals. Smaller properties are diversified.

SUMMARY

The Mushroom of the Sun (Agaricus blazei), has arisen an important scientific and economical interest on a world scale, mainly after some studies developed in Japan allowed the discovery and isolation of some substances of that mushroom, with antitumour activity. In the present study the muisture was determined by the indirect process (stove at 105ºC), lipids or ether extract (Soxhlet), proteins (Kjeldahl), ash or fixed mineral residue (at 550ºC), fiber (rude fiber), macro and micro minerals and glucides (nifext). The method of Weende that is usually used in the analyses of centesimal composition foods, was utilized. With the obtained values it was concluded that the mushroom of the sun is a food of high nutritional value, rich in proteins, fibers, minerals and with a low content of lipids.

SUMMARY

This work was designed to promote the in vitro etiolation of shoots of pineapple cultivar Perola for further recovery of those shoots. The stems utilized as explants were obtained from shoots which were already established in vitro, from which leaves were removed. The MS medium supplemented with 0.1 mg L -1 of ANA and 0.5 mg L -1 of BAP, MS medium supplemented with 1.8 mg L -1 of ANA and 2.0 mg L -1 of BAP and MS without growth regulators. Etiolation was induced by putting the explants into test tubes of 150 x 25 mm, containing the referred culture media in the dark for 20, 40 and 80 days . After that time , the etiolated shoots were removed from the tubes for evaluations of the length and number of etiolated shoots. For the varying number of shoots, the best medium was that of MS + 1.8 mg L -1 of ANA and 2.0 mg L -1 of BAP, where a mean of 10.78 shoots at 49.3 days in the dark was obtained but those shoots presented a length less than 1.0 cm. For the variable length of etiolated shoots, the MS medium without growth regulators was significantly better when the explants were kept for 80 days in the dark presenting an average length of 10.86 cm.

SUMMARY

Carcinoid tumor is a rare malign neoplasm and most oftem are asymptomatic, it originates from the neuroendocrine system, in different places of digestive tract, commonly located in 50% the ceccal appendix 50%, presenting an incidence approximately of 0.06% occuring predominantly in female adults. The carcinoid tumor of appendix area usually is assymptomatic or may simulate an acute abdominal disease, looking like acute peritonitis. It’s almost always diagnosed during an exploratory surgical act of an acute abdominal process. The size of the pathological findings almost never excedes 1.0 centimeter in diameter, being the a pendictomy the handling of choice. In presence of liver metastases the treatment of choice is chemioembolization of hepatic artery. The carnerstone of cancer diagnosis is a precocious and precise anatomical diagnosis in carcinoid tumors, tthis rule is no exception. And it is essential to have a good prognosis necessary to detect carcinoid tumors precociously and to perform anadequate surgical act as soon as possible.

SUMMARY

The last step on the cavity preparation is the bacterial reduction of this procedure. It constitutes in cleaning the debris of the walls and the margins of the preparation which may interfere in both the adaptation of the restorative material and in the carious infection which was previously installed. The high selectivity of the high intensity laser light associated with delivery systems such as optical fibers enables the therapeutical use of this light on the bacterial reduction on the cavity preparations. Aiming to understand in order to compare the different ways of interaction between these two high intensity laser systems which are largely used in Restorative Dentistry nowadays, Nd:YAG laser and Er:YAG laser, two clinical case studies will be related showing the clinical applicability and viability of both laser systems in the clinic as a decontaminant agent in cavity preparations.

SUMMARY

This work reports a study about drug consumption carried out within a population of academic students from two colleges in Alfenas, Minas Gerais state. Either licit or illicit drugs were considered. After a wide revision of the concerning bibliography and a questionnaire with about 23% of the academic students (total 6500) we concluded that there is a significative consumption of such drugs. However, the pattern of drug consuption found was similar to that of other studies condutedbefore either in Brazil or other countries. Infact, 55% of college studentsmake use drugs. The most surprising finding though was that the majority of the students who answered “ yes “ to the proposed question “ Have you ever triel any kind of drugs, including alcohol and cigarete? “ spontaneously (88%)revealed that they had consumed such drugs, and these these, before the admission to the college. This finding clearly suggests that the occurrence of na aggregation of young people into universitary cities does not represent itself the starting point to drug consumption.
