Abstract
BACKGROUND/AIM We investigated the beneficial effects of drinking tomato juice (TJ) rich in antioxidant carotenoids on irradiated skin following radiotherapy (RT) in breast cancer patients. PATIENTS/METHODS Twenty-three patients agreed to drink TJ (160 g/day for six months) after the completion of RT. Early and late adverse events (AEs) of irradiated skin were evaluated according to the Common Terminology Criteria for AEs and the European Organization for Research and Treatment of Cancer Global Cosmetic Rating System, respectively. RESULTS With regard to early AEs, acute radiodermatitis of grade 1 was observed in most patients (22/23) at the end of RT. However, the grade of radiodermatitis rapidly changed to 0, 1 month after RT and starting TJ consumption. With regard to late AEs, most patients were in good or excellent dermal condition. CONCLUSION TJ consumption could help in relieving and recovering from early AEs and decreasing the severity of late AEs of irradiated skin.

Abstract
Dosou-se a concentração plasmática de progesterona (P4) em ovelhas Santa Inês (SI), Suffolk (SU) e Romney Marsh (RM) em anestro sazonal e submetidas ao efeito-macho, as quais receberam ou não suplementação alimentar. Machos vasectomizados foram introduzidos no grupo de fêmeas após um período prévio de isolamento de 60 dias, e amostras de sangue foram colhidas antes e após a introdução dos machos. Houve efeito (P<0,01) de período, raça, interação período x raça e interação suplementação x período x raça sobre a concentração de P4. Nas ovelhas SI ocorreu aumento (P<0,01) da concentração de P4 após a introdução do macho, indicando que houve aumento na atividade cíclica reprodutiva desse grupo. A suplementação, neste caso, potencializou este aumento. Nas ovelhas SU e RM não ocorreram modificações na concentração de P4 (P>0,01) após a introdução dos machos, nem houve efeito de suplementação. O efeito-macho foi eficaz em induzir a atividade reprodutiva durante o anestro sazonal em ovelhas SI, mas não em ovelhas SU e RM, e a associação dessa prática com a suplementação alimentar é recomendada para ovelhas da raça nativa SI.

Abstract
Para verificar o efeito do estresse calórico (EC) nas concentrações plasmáticas de testosterona, triiodotironina (T3) e tiroxina (T4), oito bodes, das raças Saanen (n=4) e Alpina (n=4), foram mantidos em câmara bioclimática, sob condições de termoneutralidade (13,0ºC a 26,7ºC) durante 30 dias e, após um período (60 dias) de descanso, submetidos ao EC (23,7ºC a 34,0ºC) por 30 dias. Para minimizar as variações sazonais nos perfis hormonais devido ao fotoperíodo, durante toda fase experimental, incluindo a de adaptação em condições de termoneutralidade (30 dias), o fotoperíodo foi controlado utilizando-se alternância de dias longos (16h de luz e 8h de escuro) e de dias curtos (8h de luz e 16h de escuro) a cada 30 dias. As amostras de sangue foram coletadas duas vezes por semana durante cinco semanas. No conjunto das raças, o EC não influenciou (P>0,05) as concentrações de testosterona (1,8±0,2 vs 1,3±0,2ng/ml) e nem a de T4 (52,7±2,8 vs 50,0±2,8ng/ml). Houve declínio (P<0,01) das concentrações de T3 nos animais submetidos ao experimento (1,3±0,1 vs 1,0±0,1ng/ml), mas a redução foi observada somente nos bodes Saanen. Em ambas as raças, as concentrações de T3 e T4 variaram (P<0,01) conforme o dia da coleta das amostras de sangue. O EC foi suficiente para produzir uma resposta fisiológica com redução das concentrações plasmáticas de T3 em bodes das raças Saanen, mas não da raça Alpina, assim como não foi capaz de alterar os níveis plasmáticos de testosterona e nem de T4.

Abstract
To study the annual pattern of plasma melatonin and progesterone concentrations in hair [Santa Inês (SI)] and wool [Romney Marsh (RM) and Suffolk (SU)] ewe lambs kept under natural photoperiods at 21 degrees 59'S, 12 ewe lambs (four/breed) were used. For melatonin, blood samples were collected monthly throughout the year at the onset (17:00, 19:00 and 21:00 hr) and end (04:00, 06:00 and 08:00 hr) of the night, and for progesterone the samples were collected in the morning, two to three times a week throughout the year. Plasma melatonin concentrations at different times of the day changed according to the season. In diurnal periods (17:00 and 8:00 hr) no seasonal differences were observed but they became evident in the nocturnal intervals (21:00 and 4:00 hr) and transitional night-day (6:00 hr) times. The patterns of melatonin secretion were higher in winter and autumn than in spring and summer. The patterns of plasma progesterone secretion were affected by interaction between breed and season. There was no seasonal variation in plasma progesterone concentrations for SI females. The progesterone pattern for RM and SU females varied with season. The plasma levels were higher in autumn and winter than in spring and summer. At 21 degrees 59'S hair and wool ewe lambs showed the same annual pattern of plasma melatonin concentration while the annual progesterone profiles were quite different. For SI females this pattern was constant along all seasons and for RM and SU females this pattern was higher during autumn and winter than spring and summer.

Abstract
Para verificar o efeito do estresse calórico (EC) na produção espermática de caprinos, oito machos das raças Saanen (n=4) e Pardo-Alpina (n=4) foram mantidos em câmara bioclimática, sob condições de termoneutralidade (13,0ºC a 26,7ºC) durante 30 dias e, após um período (60 dias) de descanso, submetidos ao EC (23,7ºC a 34,0ºC) por mais 30 dias. Para minimizar as variações sazonais na produção espermática, durante todo o período, o fotoperíodo foi controlado utilizando-se alternância de dias longos (16 horas de luz e 8 horas de escuro) e de dias curtos (8 horas de luz e 16 horas de escuro) a cada 30 dias. Avaliaram-se as temperaturas retal e testicular, o volume do ejaculado, a concentração espermática, as motilidades massal e individual progressiva (MIP), o vigor e a morfologia espermática. Houve aumento (P<0,05) da temperatura do testículo (31,0±1,1 vs. 32,8±0,9ºC) e decréscimos (P<0,01) do volume (0,6±0,3 vs. 0,4±0,3ml), da concentração espermática (5,1±1,8 vs. 4,5±1,5 x10(9)), da motilidade massal (3,5±0,5 vs. 2,9±0,5), da MIP (67,4±14,3 vs. 53,3±13,1%) e do vigor (3,5±0,6 vs.3,0±0,6) quando os animais foram submetidos ao EC. O EC não influenciou (P>0,05) o percentual total de células anormais e nem a temperatura retal. Os machos da raça Saanen apresentaram temperaturas do testículo e retal mais elevadas (P<0,01) e produziram maior volume (P<0,05) de ejaculado. O estresse calórico produzido em câmara bioclimática foi suficiente para afetar, negativamente, algumas características quanti-qualitativas do ejaculado de machos caprinos das raças Saanen e Pardo-Alpina.

Abstract
A fraction of lipid-rich organelles of rat livers was analyzed to study the effect of bile duct ligation on lipid metabolism. The lipid fraction of the control rats consisted mainly of Golgi-derived dense bodies. Three days after the ligation, myelin-like figures and increased phospholipids and cholesterol were characteristic of the fraction. Two weeks ligation resulted in proliferation of lysosomal electron dense bodies. As their volume density expanded, phospholipids and cholesterol increased. Electrophoresis indicated a reduced rate of VLDL assembly after ligation. The Golgi-dominant phase is converted to the lysosomal phase in the heavy subfraction after the bile duct ligation. This subcellular change could be a consequence of secondary lipidosis: hepatocyte lysosomes have been exhausted in sorting accumulated lipids into secretory lipoproteins.

Abstract
An asymptomatic 16-year-old boy was found to have Wilson's disease without Kayser-Fleischer rings. Liver biopsy showed chronic active hepatitis with 1025 micrograms copper/g dry weight. After 19 months of d-penicillamine therapy, the liver histology became almost normal and the copper content decreased to 238 micrograms/g dry weight. The liver specimens obtained before and after treatment were studied by X-ray probe microanalysis. After treatment, both copper and sulfur decreased in hepatocellular lysosomes. The estimated molar ratio of the decreased copper to the decreased sulfur was 32/100. These figures suggest that lysosomal copper exists in the form of metallothionein.

Abstract
Energy dispersive X-ray analysis was performed on the renal tubular cells of two patients with inorganic mercury intoxication. Some lysosomes of these cells consisted of unusual matrices of aggregated electron-dense grains which were positive for mercury, selenium and sulphur. Though maps of the specific X-rays of both mercury and selenium coincided exactly with these lysosomes, the molecular ratio of selenium to mercury ranged between zero and 2.9. It is unlikely that the trace element of selenium and exogenous inorganic mercury are deposited in the lysosomes independent of each other, but rather their coexistence in the characteristic lysosomes strongly suggests a compound formed by binding mercury to the SeH residues of selenoprotein.
