264 mones. The chapter on nutrition and growth and on steroids in particular summarize clearly a large number ofexpriments. The cfkcts of ~t~t~n on hormones and 6rowth involves many variables, andthe chapter by Phillips is valuable fbr categorizing the many intemc~, and evaluating the

experimental work that has been done in this area. Knowledge of endocrine control of growth should continua to grow as increased supplies of human growth hnrmow becomeavailable through genetic engi~~n~. und as more is learned about

The third section deals with cancer treatment with a brief review of tbe current status of immunotherapy. Some novel methods for assessing i~~~~ulat~ activity are presented and in the same section John Hadden has summed up the current statoof-the-arl (why not put such a summing up at the end of the volume?f. Three articles on thymic hormones cover some deveiopments in modification of T-cell fu~tion and treatmenl of ~rnun~ proliferative disease. Inflammatory mechanisms get a look in as does aracbidonic acid metabolism in the context of nl~~~~ and basil products and r,!guIation of lymphocyte hmction. ChemcQxis, degmmdation and microbicidal act&m of rteutmphils and macro. phages are &o discussed in some detail both as biochemical phenomena and as potential immune/inflammatory models. These sections concentrate to a great

extent on mechanisms of action and, as such, provide the background for an inlmu~t~a~utic approach. A section on ‘selected (sic) topics inch&s a mixture of articles on cytotoxicity. monoclonal antibodies, allergy, CNS. ~mgens, immune suppressor substauces, and schistosomes. Finally, the summaries of ‘Therapy Communication Sessions’ again cover a wide area in&ding immu~~entiati~, interferon. mummy1 dipeptides. lymphokines and transfer fao 101. In conclusion, this book contains much useful specialist information but overall leaves one somewhat confused; indeed in this it seems to accurately retlect both the Brighton ~fem~~ and the current state of immunophannaco1ogy. However, out of such confusion order may yet come.

Tribute to excellence

The opening chapter, by Cabella. on the structure of smooth muscles is complete. well-illustrated and authoritative. Next there is a description, by Bolton. Tomita and Vassort, of the application of the voltage clamp method to smooth muscle. It is lucid and not over-technical, yet explains clearly the many problems associated with attempts to measure ionic conductances in smooth muscle. Tke inclusion of this soti of healthily scepticsl. yet not destructive. dis cussion of experimental methods is an excellent idea; there is little point in emcting elaborate hypotheses if the fallibility of tlte methods used to obtain the data is not understood. T.he same sort of healthy step tlcism is noticeable in Brading’s chapter on ionic distribution in smooth muscle. After reading it, one is left in no doubt about the problems that surround the ~~~~nt of such a basic, and apparently straightforward, quantity as the intracellular sodium concentration. Yet one also gets a good survey of the present state of knoll. The chapters by BoIton, Tomita and Vassort, and by Brading, combine review with anelementofcritical teaching which is just what is needed near the start of such a comprehensive book. The rest of the chap ters have a mom conventional review for-

I found the volume somewL1 confusing to read and feel that whilst repmducing the authors typescripts ditectly ma:! speed up publication (if one year is to be considered f&t) it does nor make for easy digestion.

one comes across a large, multi-author volume about which one can be so enthusiastic; frequently such books consist of a series of di~on~ct~ papers of variable standard. wrth many duplications and omissions. This style of publication reaches, I suppose, its nadir in the pub liihed proceedings of some symposia, in which one has the impression that a large proportion of the contributions should have a title like ‘Some snippets from my last few papers’. The new edition of Smooth MuscIe is nothing like that. It gives the impression ~~~it~have~j~~k~t~~r the 2Ocontributions. but have organized the chapter contents in a way that makes the book read like a coherent whole. And the chapters am written as mviews of the current state of research, not just as a synopsis of the authors’ own contributions.

A book which unapologeticallytackles the problems inherent in applying mathematical models to empirical biological data thereforemustat&e interest.espy clally when a treatmentof both kineticsand dynamics is found between the same covers. The purposeof Toxicants and Drugs Kinetics and Dynamics, according to its preface, is ‘to bridge the gap between pure mathematical theory. at the one extreme. and the indiscriminateapplicationof simple standardmodels to data they may not ade quately describe.at the other’. In thisobjective it is successful. Chapter I is an introduction (for the matbemalically rusty) to tbe mathemalics of kinetics and is prefaced with a useful glossaryof symbols. With admirable logic. the mathematics of saturable systems. as such, is dealt with in Cblpter 2 before all these techniques are applied in Chapters 3-5 to the kinetics of the processes of absorption. distribution and elimination under variousconditions. The theme of the three remaining chapters is pharma codynamics. covering receptor theory and time-effect and dosorrsponse relationships. II is rightly retnarked that the principle5 consideredare common to both pharmacology and toxicology. This book could be read with great profit by studentsand most otherswho work in theseareas. Each chap ter is refecnced, begins with tirst princ:L pies, is developedthroughto impurtantanu’ more complex concepts and is concluded with a wealth of problems aften derived from the Iiter;lture. but. alas. no solutions
