A histopathological study of lymphnodes in 43 cases of leprosy. | Eighty cases of leprosy including 60 cases of lepromatous type and 20 cases of tuberculoid type, during the period of 1974-75, have been examined for evidence of lymphnode enlargement. Of the 52 cases of enlarged lymphnodes, lymphnode biopsy was done in 43 cases including 38 cases of lepromatous type and 5 cases of tub... | 672,191 | [

Observations on the deep lymphatic circulation of the limbs and on its function: (the deep lymphatic vessels in the post-phlebitic syndrome of the lower extremities). | In 60% of patients with post-phlebitic syndrome lymphography of the lower extremity shows involvement of the deep system. In 77% of the patients there was increase in the number and caliber of the deep lymphatic vessels. They frequently appear elongated, tortuous, and ectatic but usually do not show signs of insufficie... | 672,257 | [

Toxicity and mutagenicity of radiation from fluorescent lamps and a sunlamp in L5178y mouse lymphoma cells. | Unfiltered broad spectrum radiation emitted by black light, cool white, and black light blue fluorescent lamps and a sunlamp, is both toxic and mutagenic to L5178Y mouse lymphoma cells when the cells are irradiated in phosphate-buffered saline. The increase in mutant frequency seen after exposure of the cells is linear... | 672,925 | [

A surprising property of electrical spread in the network of rods in the turtle's retina. | Flashing a localised stimulus onto a turtle's retina produces an intracellular potential wave which spreads through electrical connections from illuminated to unilluminated photoreceptors.

Measurement of total lung capacity by a roentgenography-planimetry method in children 4-16 years of age. | We have demonstrated the reliability of the planimetric method for the determination of total lung capacity (TCL) in children aged 4-16 in comparison with TLC measured by the plethysmography method. We have found power function formulas to be of greater potential usefulness than linear, logarithmic or exponential formu... | 674,863 | [
