[Ear-acupuncture and endocrine secretion].

We have investigated the possible influence of auricolar puncture over hormonal secretion. We have studied in 5 subjects the course of hormonal incretion determinable by only auricolar puncture and the second time making the same methodology united with the test of hypophyseal stimulation by "LH-RH-insulina-TRH". The results show that it is not get any changes of the plasmatic rates of hypophiseal hormones, while we have observed a decrease of the plasmatic hydrocortisone rate when it was practised the only auricolar puncture.

[Statistical analysis of risk factors for hypertension in obese children].

The aim of this work is the recognition, if any, of connection of arterial hypertension and some risk factors in obese children. In the schools of two little towns of our Region 114 subjects were selected, 57 males and 57 females, aged between 6, 5 and 15 years, with a body weight superior to that corresponding to the 95th percentils in the same age class. The blood pressure values were related to age and height and it was decided to consider hypertese those children whose pressure values corresponded to 95th and 97, 5th, respectively in the same class of age and height. The number of hypertese children in our group demonstrate that diastolic pressure in the height scale results especially increased among the age group 13-15 years in connection to size (females 75%, males 41, 7%). The connection between family diabetes and family hypertension have been shown significant. It can be pointed out that the risk factors for hypertension may be: age over 13 years, feminine, sex, family diabetes, family hypertension.

[Effect of sex on annual variations in plasma LH and FSH levels in prepubertal subjects].

We studied, from 1977 to 1979, 61 females and 72 males (aged 6 to 10 years) in order to demonstrate the occurrence of FSH and LH circannual variations. The data were fitted a cosine function by least square method in order to describe any rhythm and to estimate its parameters:mesor, amplitude, acrophase. Our data suggest that in prepubertal age the behaviour of FSH secretion is different in two sexes, but without circannual rhythm. LH instead shows a statistically significant circannual rhythm in both groups, without differences in mean levels between the two sexes.

[Annual variations in plasma testosterone levels in prepuberal subjects].

40 prepubertal boys, aged 6 to 10 years, were studied from 1977 to 1979 in order to evidence any circannual rhythm in the testosterone plasmatic levels. The patients observed in the following life schedule: nocturnal rest from 2200 to 0600 circa, meals at 0800, 1300, 1900. Plasma samples were taken at 0800 and testosterone was assayed by RIA. Testosterone data were fitted a cosine function, by least square method in order to describe any rhythm and to estimate its parameters:mesor, amplitude, acrophase. A significative circannual rhythm in the testosterone levels is present (P= 0.008) with Acrophase in July (-198.38 degrees +/- 18.26 ES). Our study suggests that a significative testosterone rhythm, with circannual periodicity, is present also in prepubertal age.

[Symptomatologic value of skin evaporimetry].

Skin significantly contributes to water turnover excreting 300-600 ml/Day, this aliquot being under the control of several factors, including psychologic factors. The cutaneous evaporimetry offers semeiological parameters useful to study water balance. Our work is an extension of the classic experiments of G.E. Nilsson and coworkers. In the present report evaporimetric measurements are related to 15 normal subjects at ours climatic conditions.
