ABSTRACT
BACKGROUND: The trauma resulting from liposuction damages the subcutaneous cellular tissue and subsequently the lymphatic structures. In turn, this damage can reduce lymphatic drainage, which may or may not appear clinically as some degree of edema. OBJECTIVE: It is possible to evaluate the function of the lymphatic system using lymphoscintigraphy. We conducted a study to evaluate the lymphatic system using this technique both before and after liposuction of the lower limbs. METHODS: The study included seven women ranging from 18 to 42 years of age, all of whom were diagnosed with lipodystrophy solely in the lateral and medial regions of the upper third of the thighs. This study was conducted in three stages: preoperative lymphoscintigraphy, liposuction, and postoperative lymphoscintigraphy three months postoperatively. The Wilcoxon signed-rank test was used for the statistical analysis of the results. RESULTS: A comparison of values for the average time of the radiopharmaceutical acquisition curve and clearance in the areas of lymphoscintigraphic interest both before and three months after liposuction did not reveal significant results. CONCLUSIONS: A comparison of preoperative and postoperative lymphoscintigraphic findings showed no significant damage to the lymphatic system associated with liposuction of the lower limbs.

Velvet bean plants (Mucuna pruriens) are used widely outside the U.S. as a cover crop. The beans (VB), high in protein, contain toxic substances that possibly can be destroyed by heating. Few data are available on the use of VB in poultry nutrition. We examined the effects of raw and dry-roasted VB on broiler performance in two experiments. In Experiment 1, 10, 20, and 30% raw VB were substituted into nutritionally balanced rations fed 0 to 42 d of age. Raw VB caused progressive reductions in growth; at 42 d of age, broilers fed 30% VB weighed 39% of controls. Feed intake declined significantly only with 30% VB. Feed efficiency decreased significantly with 20 and 30% VB. In Experiment 2, 10% raw VB and 10, 20, and 30% heated VB were fed 0 to 42 d. With 10% raw VB, broilers grew significantly slower but feed intake was unchanged. Inclusion of 10% heated VB allowed better growth than raw VB, and by 42 d of age, growth was not significantly different from that of controls. At 20 and 30%, heated VB promoted much better growth and efficiency than raw VB in Experiment 1, but values were significantly lower than those of controls. With 30% heated VB, broilers grew to 66% of control, a marked improvement over raw VB. Carcass yield was unaffected. Trypsin inhibitor activity but not L-3,4-dihydroxyphenylalanine (L-DOPA) in VB was destroyed by heating. We conclude that dry heating of VB partially destroys its growth-inhibiting factor(s), allowing successful use of 10% heated VB in broiler rations. Higher levels of heated VB reduced broiler performance, although results were much better than those of raw VB.

Para avaliar o efeito da compressäo pneumática intermitente sequencial sobre o transporte do Dextran marcado com tecnécio 99m em pacientes com linfedema de extremidades inferiores estudamos 11 pacientes.Foram oito mulheres e três homens com idade média de 44,6 anos.Foram realizadas duas linfocintilografias: a primeira considerada o controle (sem compresäo); a segunda foi realizada com compressäo pneumática de três horas, iniciada logo após a injeçäo do radioisótopo.Antes do início da compressäo e logo após o término foram feitas medidas em seis locais marcados para verificar a efetividade da compressäo na reduçäo do volume da extremidade.A análise quantitativa foi realizada pelo cálculo do "clearance" do radioisótopo em quatro locais determinados (perna, joelho, coxa e regiäo inguinal) em ambas as linfocintilografias.Observou-se reduçäo significante entre dos diâmetros das extremidades, porém näo foi observada diferença significativa entre os valores do "clearance" sem e com compressäo.Concluímos que a compressäo pneumática intermitente sequencial foi efetiva para reduzier o diâmetro, porém näo alterou o transporte do radioisótopo nas extremidades estudadas, em três horas de compressäo.

Subjective and objective systems are used to quantify cataract at The Center for Clinical Cataract Research. We have described each system and its use, presented data on reproducibility and validity, and for objective systems, demonstrated the correlation to the subjective grade of the cataract as defined by the Lens Opacities Classification Systems, Versions II and III (LOCS II and III). The subjective systems are used to classify nuclear color, nuclear opalescence, cortical cataract, and posterior subcapsular cataract. Reported kappa scores for LOCS II range from 0.85 to 1.0. Intraclass correlation coefficients for LOCS III (r1) range from 0.67 to 0.94. The computerized objective system are: (1) fast spectral scanning colorimetry (FSSC) for assessment of nuclear color (r1 = 0.96 to 0.98); (2) nuclear mean density (NMD) for assessment of nuclear opalescence (r1 = 0.97); and (3) percent area opacity (anterior = a; posterior = p) (OPAC-a and OPAC-p) for assessment of cortical and posterior subcapsular cataract (r1 = 0.92 to 0.96).
