This study was carried out at the Department of Plant Production, Sector Horticulture, São Paulo State University-UNESP, Botucatu Campus, São Paulo State, Brazil in order to evaluate the effect of sources and increasing doses of potassium in roots of eggplant. The experimental design was randomized blocks in factorial scheme 2 x 4 (two sources of potassium: KCl and K(2)SO(4) and four doses of K(2)O, 250, 500, 750 and 1000 kg ha(-1)) and three replications. For the experiment, we used Oxisol medium texture (615 g of sand, 45 g of silt and 340 g of clay per kg soil). The soil passed through sieve of 5 mm and packed in plastic pots with a capacity of 32 liters of soil where plants were grown. The pots were distributed with a spacing of 0,63 m between plants and 1,0 m between rows each pot being grown with a plant. The evaluated characteristics were: root dry mass and volume of the root. It was concluded that sources and excessive doses of mineral K(2)O induces stress in eggplants and affect the roots being less harmful K(2)SO(4) source.

O trabalho teve por objetivos verificar as alterações da densidade mineral óssea e as alterações bioquímicas, no hiperparatireoidismo secundário nutricional. Foram utilizados 10 gatos, sem raça definida, com idade inicial entre 2 e 3 meses e peso médio de 820 gramas. Após um período de adaptação de 10 dias, eles foram submetidos a uma dieta composta por coração bovino moído e cru durante 60 dias, sendo os exames efetuados no final do período de adaptação e a cada 15 dias. Empregou-se o método de densitometria óptica em imagens radiográficas, do rádio e ulna direitos. Não foi observada diferença estatística na densidade mineral óssea entre o final do período de adaptação e com 15 dias de alimentação com carne de coração. Aos 30 dias, houve uma diminuição significante estatisticamente, que se manteve no mesmo patamar aos 45 e 60 dias. em nenhum momento de observação ocorreu diferença estatística nos níveis séricos de cálcio e fósforo. Os níveis séricos de fosfatase alcalina variaram e estavam acima dos valores normais no 45º e 60º dia da dieta. Foi possível concluir que a densitometria óptica em imagens radiográficas é um método eficiente de avaliação da desmineralização óssea, ao passo que as análises bioquímicas séricas de cálcio, fósforo e fosfatase alcalina são de valor limitado.

Os debates e as ações feministas em prol da liberalização do aborto no Brasil foram marcados por avanços, recuos e, sobretudo, por inúmeras negociações políticas. da omissão da palavra aborto, em meados dos anos 70, à opção política pela descriminalização e pela realização dos casos previstos por lei, observa-se uma vocação política do feminismo brasileiro para a negociação. Conclui-se que essas negociações tiveram mais êxito em nível político do que social, pois não lograram alcançar e sensibilizar camadas mais amplas da população.

The main goat of this work was to evaluate the effects induced by mannitol- water stress in the initial growing of cotton plants. The experiment was conducted as a completely randomized design, in factorial design 4 x 5, with 3 replications. Treatments were generated by the combination of four cotton cultivars (LD CV Frego; LD CV 02; FMT 701 and IAC 25) and five levels of water stress (0; -0.3; -0.6, -0.9 and -1.2MPa), obtained with mannitol solutions. Water potentials of -0.9 MPa reduced significantly the rate of cotton plants growth. The decrease of the water potential reduced the production of dry mass of the aerial part of all cultivars and increased the production of root dry mass on -0.6MPa potential. LD CV 02 cultivar exhibited a superior performance under water stress.

The aim of this study was to analyze the morphoquantitative features of the nitrergic myenteric neurons from the body of the stomach of diabetic rats. The body of the stomach of five normoglicemic rats and of five diabetic rats were prepared as whole-mounts stained by the histochemical technique of NADPH-diaphorase. Decreased body weight and increased daily ingestion of water, fast glicemia and glycated hemoglobin were verified in diabetic animals. According to the data obtained, significant difference in the density of nitrergic neurons was not observed between the two groups, but the areas of the neuronal cell body profiles in the diabetic rats were significantly larger. Results showed that the streptozotocin that induced diabetes does not accelerate the death of the nitrergic neurons, but increases the expression of these cells.

Many plants, even without scientific confirmation, are used in Brazil as hypoglycemic. The objective of the present work was to study the influence of the Allium sativum treatment, plant known popularly as garlic, on characteristic biochemical parameters in streptozotocin-induced diabetic rats. Female Wistar rats were injected with 40 mg kg-1 streptozotocin (STZ). Oral administration of an aqueous extract of A. sativum was given to the diabetic animals in 2 doses: 200 and 400 mg kg-1 (n=6 animals/group). Diabetic rats given distilled water constituted the control group. After 28 days of treatment, the female rats were anesthetized and died by decapitation for collection of the blood for biochemical determinations and retreat of liver samples for hepatic glycogen dosage. The treatment with Allium sativum in the doses of 200 and 400 mg kg-1 alter no concentrations of total proteins, hepatic glycogen, triglycerides and VLDL, but it promoted reduction in the total cholesterol rate (control=280.5 ± 30.9; 200 mg kg-1 A. sativum =169.9 ± 19.5 and 400 mg kg-1 A. sativum =148.4 ± 26.6 mg dL-1) and LDL (control=128.8± 25.3; 200 mg kg-1 A. sativum = 41.4 ± 16.2 and 400 mg kg-1 A. sativum=42.0 ± 26.0 mg dL-1). The extract presented beneficial effect because it decreased 13.0% of glycemia in the highest dose. Therefore, the of garlic extract reduced the HDL concentration in two tested doses (control= 81.4 ± 30.2; 200 mg kg-1 A. sativum=49.6 ± 14.3 and 400 mg kg-1 A. sativum=41.7 ± 16.1 mg dL -1), presenting impaired effect. Thus, the garlic extract showed efficiency in the analyzed experimental conditions, and it could be used as complementary therapy to diabetic patients.
