Amiloride pharmacokinetics in rat.

The kinetics of amiloride was investigated in plasma, urine, faeces and tissues of rats after oral (10 mg/kg) and i.v. (10 mg/kg bolus and 35 microg/h for 4-days infusion) administration. Initially the experimental data were analyzed by a multiexponential model, then a compartmental model was developed to describe the drug kinetics in plasma, urine, faeces and tissues after the i.v. bolus and the oral administration simultaneously. Aim of the model was also to predict the drug kinetics in plasma and tissues of rats after continuous i.v. infusion. The results of the prediction and the discrepancies between prediction and observed data allowed a deeper insight into the pharmacokinetics of amiloride.

Inhibition of ornithine-decarboxylase produced by S(+) and R(-) ibuprofen in rats.

The differences between the S(+) and R(-) ibuprofen enantiomers in anti-inflammatory activity were assayed by measuring the release of 14CO2 in rats treated with labelled 14COOH-ornithine. Furthermore we investigated in vitro the inhibitory activity on ornithine-decarboxylase and the anti-inflammatory activity of R(-) and S(+) ibuprofen by using the carrageenin-induced paw oedema test in the rat.

Synthesis, binding affinity and selectivity of new beta 1- and beta 2-adrenoceptor blockers.

The synthesis of a new series of sesamol derivatives with beta-adrenergic blocking activity is described. The affinity and selectivity of these compounds for beta 1- and beta 2-adrenoceptors were studied in comparison with those of ICI-118551 and propranolol. Some of the synthesized compounds show very good affinity for the beta 2-receptors of rat lung membranes and two of them provide interesting selectivity.

[Anthropometric nutritional status and food habits of students of the secondary schools of Umbertide (author's transl)].

A survey has been carried out on anthropometric nutritional status and food habits of students of the secondary schools of a little town of Umbria that is now in an economic development. The anthropometric data (body weight and height, skinfolds, diameters, muscle and fat areas and body mass index) show that in the girls the body fat mass is higher than in boys and american girls of the same age. The boys of professional men are fatter than the boys of workmen. The survey of food habits (using the method of frequency of occurrence for three days) shows that milk, eggs, legumes and cheese are not frequently consumed, while meat (particularly beef and veal), alcoholic beverages, animal fats and sucrose occur rather frequently in the diet. The excess of body fat mass and the biological and economic errors in the diet of these children need to be corrected with a nutrition education program. It is well recognized that both diet and physical activity play an important role in the prevention of metabolic degenerative disease and this prevention has to be started as early as possible.

[Model for the regional allocation of the National Health Care Fund].

In 1978 a National Health Service (Servizio Sanitario Nazionale = SSN) was constituted in Italy which exercises jurisdiction in the sector of health care and is duty bound to assist all citizens. Basically speaking, the NHS is organized on three levels (national, regional and local) with the management of direct operations assigned to the (about 700) Local Health Boards (Unità Sanitaria Locale = USL) each of which covers a well determined territorial area. The Authors indicate that rarely discussed or evaluated are the procedures for the regional allocation of health care funding which is determined by Parliament within the ambit of the National Budget (The National Health Care Fund). The current allocation model distributes the available capital resources for each expense item (e.g. hospitalization, pharmaceutical assistance, etc.) on a per capita basis with respect to the regional populations modified in order to allow for differing degrees of health care requirements. The regional populations are subdivided into broad age groups (e.g. children, intermediary, the elderly) with specific weighting factors expressing the different level of health care requirements. The application of these weighting factors alters the regional populations (with no change in the total population of the country) in order to express them in equivalent units with respect to the health care need. Moreover, standardized death rates are introduced into the model as indicators of the different health risk, and their application leads to a further modification in the level of the regional populations so as to express them in equivalent units with respect to the health risk as well. Once the available financial resources have been subdivided in this "theoretical" way, the following corrective factors are applied: a) hospital mobility correction factor: the regions with a credit admissions balance are assigned an additional cost which is borne by the regions with a debit admissions balance; b) historical expenditures correction factor: a comparison is made between the theoretical allocation and the allocation according to expenditures ascertained in 1985, and the final allocation falls into an intermediary position; s) Local Health Board income correction factor: the assignment of funds is reduced in direct proportion to the estimated income specific to the Local Health Boards of each region. The authors point out that even though this model represents a positive evolution when compared to the superficial criteria of past expenditure levels, it does manifest application potential limits.(ABSTRACT TRUNCATED AT 400 WORDS)

[Nicolau syndrome caused by penicillin preparations: review of the literature in search for potential risk factors].

The Authors, who in 1977 published the first Italian case report of the Nicolau syndrome (N.S.) from penicillin preparations in the pediatric field, accomplished a thorough search for similar reports in the world literature finding a total of 102 cases, of whom 80 were less than 12-year old. They made a detailed analysis of each case in that series in order to identify or better define potential risk factors or predisposing circumstances worth being taken in consideration for preventive purposes. Indeed, the possible occurrence of N.S., which may include devastating complications such as limb gangrene, paraplegia, or death and have medico-legal implications, is still largely underrated or unrecognised by both physicians and nurses. It is unfortunate in particular that no acknowledgement of that syndrome is available in the teaching programs and textbooks used in professional nurse schools; in addition physicians are not enough zealous in discouraging unqualified lified people as well as patient's relatives from performing intramuscular injections, mainly using certain kinds of drugs such as crystalline suspensions. On the basis of the findings of their analysis as well as of an overall review of the relevant literature the Authors conclude their paper by making a series of specific recommendations and/or proposals addressed to the various operators involved in the matter (prescribing physicians, managers of nursing schools, nurses, pharmaceutical companies, Regulatory Health Authority), with special emphasis on the precautionary measures to be taken in doing intramuscular injection of long-acting penicillins or other drugs in crystalline suspension.
