Book Description
Ultrastructure in Biological Systems, Volume 2: Ultrastructure of the Kidney provides an overview of the state of knowledge on the ultrastructure of the mammalian kidney. The application of the electron microscope to studies of the kidney resulted in the demonstration of the hitherto undetected early thickening of the basement membrane of glomerular capillaries in glomerulonephritis. Yet many problems remain, particularly in relation to the correlation between function and the ultrastructure of components of the kidney—mesangium, glomerulus, juxtaglomerular apparatus, and the renal tubules. It is only recently that the mesangium has come to be accepted as real, and many questions remain as to the function of its cells. The existence of true membranes between foot processes of the epithelial cells of glomeruli is a newly established fact; but what this has to do with glomerular filtration is not known at present. Granules apparently secretory in nature have been identified in cells of the juxtaglomerular apparatus, but so far their presence has not been correlated with specific functional change. Artifacts introduced at fixation are now known to have considerable relevance in interpreting the ultrastructure of the normal nephron. These are paraphrased views of the contributors to this monograph who, while acquainting the reader with the research being carried on in these areas, have also brought into focus the many problems still awaiting solution.

Book Description
This volume, focusing on the ureter and the diseases which involve it, is an updated second edition. Many journals and textbooks deal with the physiology, pathology, diagnosis, and therapy of derangements of the urinary tract. In most instances, however, the discussion properly centers on the disease process itself and its primary aspects, with only a tan gential description of effects on the ureter. The editor is therefore correct that the ureter itself should be considered a major organ. Though it has been regarded in the recent past as a simple muscular tube, reacting to stretching or filling by contraction, this simplistic view of ureteral phys iology is changing fast. With expanded knowledge of ureteral physiology, a pharmacology is developing which is becoming useful to the clinician in many ways. One of the most interesting aspects of the ureter is its role in inducing the permanent kidney, the metanephros. Relatively slight displacements in the origin of the ureteral bud result in ectopic ureteral orifices and a wide range of congenital anomalies. An ureteral bud which arises medial to the normal position at the genu of the mesonephric duct results in a lateral, and usually incompetent, ureterovesical junction after the duct is taken up to form a portion ofthe trigone. This appears certainly to be the developmental mechanism which results in primary reflux.

Book Description
The Kidney: Morphology, Biochemistry, Physiology, Volume I focuses on present knowledge about the kidney under normal and pathological conditions, as manifested by morphological, biochemical, and physiological studies. The selection first takes a look at the embryonic kidney and the general anatomy and histology of the kidney. Discussions focus on the morphogenesis of transient kidneys, physiology of the fetal nephron, renal malformations, vascularization of the kidney, uriniferous tubules, and innervation of the kidney. The book then examines the histochemistry of the kidney and ultrastructure of the normal and pathological glomerulus. The manuscript ponders on electron microscopy of uriniferous tubules and ultrastructural pathology of tubules and interstitial tissue. Topics include proximal convoluted tubule, basement membranes of the tubules, capillaries, interstitial cells, morphology and functions of the tubular epithelium, fixation and preparation of tissues for electron microscopy, and structure of the submammalian vertebrate tubule. The selection is highly recommended for morphologists, biochemists, physiologists, pathologists, pharmacologists, and clinicians.

Book Description
An account of the different morphologies of vertebrate respiratory organs and structures. It explains the essence of different functional designs and strategies that have adaptively developed for the acquisition of molecular oxygen and elimination of carbon dioxide. The origins of the various respiratory systems are presented and debated from evolutionary, phylogenetic, behavioural and ecological perspectives. The book carefully outlines the interactions between the environment (the physical realm) and evolution and adaptation (the biological domain) that have set the composition and patterning of extant animal life.

Book Description
In one golden age of medicine epitomized by William Osler, the physician also aspired to mastery of gross and microscopic pathologic anatomy. Now another such age has dawned in which ultrastructure and immunopathology provide insights into mysterious diseases of the kidney, connective tissues, joints, and muscles, among other sites. Dr. Anil K. MandaI has a background in clinical nephrology, experimental pathology, and diagnostic pathology of renal diseases that suits him well for his chosen task. This is to explain clearly the clinicopathologic entities seen by nephrologists, using the full range of available morphologic techniques. His ap proach is brisk and incisive. To read his monograph as a pathologist is to make oneself a better clinician, and as a physician is to improve one's grasp of pa thology. Such correlative knowledge seems at present the means most likely to lead to the ultimate control of some crippling chronic renal diseases. Sheldon C. Sommers, M.D.
