The direct measurements of AVP during water deprivation and salt loading demonstrate the inability of the direct water deprivation test to distinguish accurately between several forms of polyuria. Polyuria and polydipsia are commonly formed disorders in the dog and can be caused by osmotic diuresis; deficient release of anti-diuretic hormone-arginine vasopressin (AVP); a decreased renal response to AVP; excessive water intake. The differentiation between these forms often requires a water deprivation test followed by administration of vasopressin. ⋯ With this it is usually possible to differentiate total neurogenic diabetes insipidus and total nephrogenic diabetes insipidus. However, several dipsogenic forms and partial diabetes insipidus forms are still very difficult to distinguish from each other and only the direct measurement of plasma AVP (PAVP) can give conclusive information. The role of AVP in osmoregulation was investigated by measuring plasma osmolality (Posm) and PAVP during; hypertonic saline infusions; water deprivation in both healthy experimental dogs and in dogs with polyuria.

In Part II of this review, recent aspects in shock therapy are discussed. Treatment of an animal in a state of shock is not an easy task, it is time-consuming and expensive. The basic aims of shock therapy are to remove the inciting cause (wherever possible), to increase the circulating blood volume in order to stimulate the cardiac output and tissue perfusion (by infusion of fluids and eventually vasoactive substances), and to reduce or correct the injurious effects of shock (oxygenation, corticosteroids, antibiotics, energy or substrates, vasoactive substances, diuretics, regulation of the acid-base balance, stimulation of RES, and treatment of DIC).

The question whether the editors of scientific journals should apply ethical criteria in addition to scientific and stylistic standards in assessing copy submitted, is discussed. This applies particularly to studies which cannot be justified by arguments that appeal to a large majority. ⋯ The instruments available to the editors in this case are (1) refusing the paper or (2) accepting the paper with a view to provoking a discussion of the questionable point. The last-named possibility offers the additional advantage that those who are not directly involved will also be able to express an opinion.

Comparative Study[The use of the problem-oriented medical record in veterinary medicine].
The problem-oriented medical record is compared with the classical, source-oriented record, with special reference to the following aspects: --as an aid in the treatment of patients; --as an aid in the communication between clinicians; --as an aid in retrospective studies; --as an aid in veterinary medical education. The problem-oriented medical record is found to be superior to the classical record in every aspect, though keeping records is time-consuming, which holds good particularly for the input of information. This interferes with large-scale acceptance, but introducing some elements of the system is worth considering. This is particularly true of the diagnostic and therapeutic scripts, which constitute a valuable addition to any type of medical record.

Those forms of behaviour in which cats use their claws are reviewed. Forms of undesirable use of the claws and possible solutions to this problem are discussed. ⋯ Approximately seventy-five per cent of the veterinarians taking part in the inquiry advocated that the Royal Netherlands Veterinary Association should state its position with regard to declawing. It is concluded by the present author that declawing is unacceptable for ethical and ethological reasons.
